I think this better to be posted to Galaxy S I9000 Android Development.
So I posted it once more at here:

Board Admin, please feel free to delete this.
Hi all,
I took so many from here. It's time for me to contribute little to the community.
The lag issue of Galaxy S bother many ppl.
I tried many different method.
Yes the lag issue was improved and Quadrant score is higher.
But there are always some weird things happen... like sudden lag/black screen.
After I upgraded to firmwre I9000ZSJH1, the lag issue is improved a lot!
But still, there are rooms for improvement.
So I wrote a cmd which will help to generate a .sh file, which will move apps data stored under /data/data/ to the internal NAND memory (/dbdata/data) for faster access.
The Galaxy S built in 1xxMB of fast access NAND memory. It is a waste if we don't utilize them.
However, it is impossible to move all apps' data to the tiny NAND memory.
So here is a tool for you to customize what app's data you want to move.
Recommand to move the core Android apps and the apps that you use frequently.
Like Dialer, Contacts, Dolphin Browser, Facebook, Astro File Explorer......
Steps :
1. open [1.app.list.xls] and edit colume A and B.
colume A should be the data folder name of the apps you want to move.
colume B is the name of the apps (optional)
2. after you've done, simply "copy & paste" everything onto a notepad and save it as [2.apps.list.txt]
3. fireup the [3.Apps2NAND.cmd]
4. within few sec, a file [App2NAND.sh] will be created.
5. use Gscript to load and run the App2NAND.sh file. (the script requires root access. so make sure you have it!)
For experienced user :
Step 1 actually is just for user to manage the apps more clearly.
A user with little cmd knowledge may know the script only requires [2.app.list.txt] to work with.
You can skip Step 1 and directly go to Step 2 to edit the file.
The format should be { app data folder name + <tab> + app name }
Remarks :
Apps that moved to NAND may not be restore with Titanium Backup.
App link will be broken by doing so.
(I also include Linpack and Quadrant to the app list to cheat higher benchmark scores . You may remove it if you don't want to.)
Apps2NAND - fast data access - choose what to move! [added support for Froyo]
update 18 Nov 10:
Found some friends here still want to use this "old school" lagfix
1st of all, thanks to your support.
When I wrote this script, it was still the golden age of Eclair (2.1). So the script is definitely not prepared for Froyo (2.2).
However, just by changing few lines can make this script survives on Froyo. So here I updated a script for Froyo (apps2nand.Froyo.zip).
I haven't tested it since I am very satisfied with the [Spike Speedy Edition v3.0 OC], which comes with more advanced lagfix options (sztupy).
(I wrote something that even myself don't use now.... So it's really suprised and appreciated~)
But this script still has it merit ~~~~~~~~~ simple!
(and battery friendly, just a feeling~ no actually statistic~)
If you are interested in antique and brave enough, try it on Froyo. And let me know if any issues. I will try my best to fix.
===================================================
update 18 Aug 10:
Now included Installation and Uninstallation for this script.
Tried several times on my i9000 and it works.
Please read and follow the readme.txt inside the zip.
One tricky part for this script : it will failed when SU permission is not allowed in time during the script is running.
I have pause the script with 10 secs for you to allow the SU on i9000.
Make sure you allowed it.
If you failed to do so, no worry. it won't change anything.
Just simply re-run the script again.

Is NAND where devices like HTC Desire and Nexus One store their Apps?
well this is almost what paul did some days after the phone got released...

Yes, which is why they needed APPS2SD in Froyo.
So....when are you posting the script?
If you want I'll create a program that spits out the .txt file rather than do it in excel, copy paste etc.

yes. that's what Paul did as I mentioned in my script.
But he simply push everything to NAND which oneday, you will find out of space.
Using my script, you can decide what to move, depending on the frequency of the apps usage.

the excel is just for user to maintain their app list easily.
my script only works with the txt file.
you may skip the excel part if you like.

Is it possible to make a script that automatically moves smaller apps to the nand?
I mean it's not worth moving large games, but anything under 2MB should be considered.
Maybe use some intellegent calculation, if all the apps under XMB use less than 50% of free space on nand, increase X until it is efficiently used up.
Also there is HEAPS of space to be freed in NAND, delete stock ringtones, and other.
seems great
hmm, would moving to nand make those specific apps run faster than they would be if they were previously running under ext2/3/4 partitions provided for by the various lagfixes out there?
What happens if an app in the list is not on the phone, does it just skip it?

sturmeh, that requires more complex scripting skills, which is out of my knowledge...
and I think instead of choosing the apps2NAND depending on size, I think the "Frequency" of using the apps may be more appropriate.
e.g. I use TouchPal IME a lot. So I move it to the NAND.
Now when I type, TouchPal act lightening!!!
MiG123, I haven't done a serious comparison. But as I remembered, Apps2NAND gives me more "smooth" feeling.
Actually, you shouldn't compare Apps2NAND to other Apps2SD or EXT.
Since Apps2NAND only offers you around 1xxMB of app storage space. Way too far from the others experts' methods.
I suggest using this is because I am using the latest 2.1 ROM, I9000TGYJH1 (http://www.multiupload.com/UTKSZPTKCG), which the lag problem seems improved a lot. But on top of it, I don't want to waste that 1xxMB of internal RAM, so I introduce this method.
To let user choose what core apps that should be put into NAND so
- space is not wasted.
- certain apps enjoy even faster response time.

Where's the file? Can't seem to find it on the first page
Anyhow. Do you symlink the old location to the new location, thus being able to keep the link intact? That should sort out any problems with backup solutions such as Titanium Backup.
How do you find the app's data folder name?

mekwall, sorry. removed by mistake.
have uploaded back again now.
yes. it uses symlink method (from Paul's concept) :
ln -s /dbdata/data/appsname /data/data/appsname
i dunno how's Titanium Backup works but it just failed to restore any apps that has used Apps2NAND...
that's why i provide the Uninstallation method to restore it back and then run Titanium Backup to backup all apps and data.
lyno, you may try the Astro File Explorer (market).
It has a function to backup the installed apps out to /sdcard.
The name of the backuped apps will be named exactly the same as it's data folder name.
e.g. Brut's Google Map -> brut.googlemaps.apk
this whoe procedure demands root-access, right?
yes. since it involves moving folders between /dbdata and /data.

I've a strange question that might or might belong in the development thread, but figured since it's a question, I'll try here first.
I'm using a Stock DeOxed Rooted Rom on my EVO.
I recently installed a few more apps and saw this pesky little warning about low on space.
When I went into my "SystemPanel" app to see how much space was left exactly and noticed that my /data folder only had around 30megs out of it's 428M available.
Ok.. time to delete some apps I thought, but then I noticed that my /system folder (Where I presume pre-installed apps live) had almost 1/3 of it's space still available (115 out of 350megs available).
So I'm wondering.....
Is there some method that I can use to install Apps directly to this folder instead of the standard /data that apps appear to go to when installed?
Is it as simple as moving the APK file with Root Explorer, or are there some under the hood items in apps that prevent this sort of thing?
I've a few rather large apps that I cannot move to the SD card due to widget problems and the like but would be perfect for the system folder if I can find a way to move them there easily.
Thoughts?

/system/app is where system apps are kept. If I remember correctly, any app can be installed into there, but you have to do through flashing an update.zip if I'm remembering properly. You may be able to take the apk that's in /data/app for the app you want to move and move it to /system/app, but I'm not sure if that will work properly or not. Someone who cooks ROMs might know more.
Also, you can partition your sd card and use true apps2sd with most ROMs. Its a little bit of work and will shorten the life of your card, but that gives you a lot more room if you need it.
I don't know that there's a way to move user apps to system. It's very possible there is a way, I've just never seen any posts about it. Apps 2 SD is usually the way to go.
ps. 30 megs?!?! Geez, how many apps do you have?
Sent from my SUPERSONIC
Easy peasy
First, use a true apk backup tool to backup e apk files you want to move. Titanium backup will NOT work because it compresses and distorts, and we need true apk files. I recommend file manager by adao team. Just go to applications, check what you want, and hit backup. Next, get the apk files on your computer by mounting sd and copying files from backups folder. You will lose all app data, but what can you do? Next, adb push the files to system app folder while in recovery mode (just say so if you don't know how to do this and i will tell you) and reboot. Done. Tell me if it works well.
By the way, 30 megs???
Doesn't froyo install to the sdcard if you tell it to?
I thought a2sd was obsolete
You can put apps there after changing the folder's permissions but I wouldn't recommend it. Just not a good idea to put regular apps there.
Just install them to your SD card instead
Sent from my PC36100 using XDA App
go into the android app manager and go through all your programs and click on move to sd card...
they will all still occupy some space on your nand, but not nearly as much.
Thanks for the advice, I thought it might not be as easy as moving them, oh well, just seems a shame for there to be over 100 megs I cannot do anything with.
I already had moved all I could to the SD card prior to posting this, but thanks for that advice as well, I'm sure others forget they can do that with Froyo.
As for the 30 megs I had left.. we'll it's back up to about 70 free which should be plenty for a while. (Remember we only have about 420 to start with).
Some of the big ones which could not be moved to the SD card are:
Swype (Deleted, took over 17megs)
TouchDown (12 megs.. must keep for tasks sync sadly)
Google Maps update (7.6 megs)
Documents to go (8megs)
A few various games that cannot yet be moved to the SD card at around 5megs each..
The rest are just lots of little apps.. I'm sort of an app junkie You should have seen my old Palm Centro... it was amazing!
According to Titanium, I currently have 194 'User apps', though I think a few are simply widgets, icon packs and the like.
Hi all,
I have been a winmob user for over 5 years and i know pretty much everything about them. (see join date) Though 3 days ago i got a a8183 desire.
My god i have a lot to learn about Android. Winmob seemed so much simplier to pick apart with registry and custom roms.
Anyways i have been reading thread after thread for days yet i still have a couple of questions that i cannot get clear answers for.
I have a a8183 telstra desire running on optus. I have updated to the latest offical 2.2 ROM. (Everyone mentions OTA (over the air) though i downloaded it and installed thru windows).
So i would appreciate if someone could help me out with my questions/assumptions.
1. From what i have read you cannot r00t a froyo OS. Is that right? Though i have found an app z4root that will do it temporarily until reboot. Unrevoked doesnt seem to work.
2. To change system files you need not only root though you need the clockworkmod recovery part of the bootloader. (eg. to replace HOST file for adblocking).
3. You need permanent r00t to install the clockworkmod (so i cannot do this).
4. You cannot remove default ROM apps from your phone without the clockworkmod.
5. You need clockworkmod to install custom ROMs.
So from what i gather.. r00t is good. though really only cause it gets you the clockworkmod recovery which is where you can really hack it.
And to get this i need to downgrade to 2.1, r00t, clockwork then use a hacked rom for 2.2?
Your help is greatly appreciated.
hi sage, i too came from windows mobile so i know how you feel, lucky for me i jumped on the android bandwagon earlier with the htc hero, after i got bored with my HD1, anyway your wrong on quite a few points, so i'll point you in the right direction.
1) the latest version of unrevoked (www.unrevoked.com/recovery) is more than able to root the froyo roms, its a one click app and can root your device in minutes
2) to easly modify system files you need s-off (this is equivalent to HSPL on wm devices) after you have rooted, you need to search for alpharev, this is a linux live cd, you just burn it and boot it and it will security unlock your device.
3) when you download and run unrevoked, it will not only root your device but insatall the latest version of clockworkmod recovery. (just hold vol down and power when your device is off to access hboot, and choose recovery from the list) so unrevoked kills 2 birds with one stone
4) to remove the apps in the /system/ partition there are 2 ways, from recovery using adb, or if you flash the s-off mod, you can remove them directly from your device using a file manager.
5) yes you need clockworkmod or another custom recovery to install custom roms, but now you know how to do it, thats not a problem
Hi Sage,
If you're looking for an easier way to get rid of all the Telstra apps (more like a blob of links really ) on your phone you may want to try one of the stock HTC WWE ROMs. It's clean and you can flash it via exe, just like in WM. The latest RUU I believe is the 2.29.405.2. Also, be aware of the risks of rooting your phone.
thanks for your response guys
Ok so i am now r00ted and running Leedroid's WWE ROM! (thank you!) it was actually pretty easy.
I think unrevoked was failing cause i was using a USB HUB.
OK so now i just want to remove some more of the default apps that come with it.
So i will try alpharev to security unlock my device. (is this permanent or if i reflash my rom it will come back?)
once i have done this i can then delete anything i like thru r00t explorer?
At this stage i am trying to just make some more room for apps. As a number of them wont move to SD Card.
A couple of last questions if i may. I have an new SD Card on order. Am i able to simply copy everything from my existing SD to my new and then swap it over in my phone and it will all be ok? Or do i need 'clone' it with some tool?
Where in the system paths do i remove 'shortcuts' within all apps? (or even simply rename them.)
Much appreciate your help. Android is growing on me. I especially love adb logcat!
ok.. i am now security off'd alpharev worked a treat.
i am now using r00t explorer to try and delete items from /system/app though they come up read-only so i cannot delete them
i take when i get to remove these the phone will have more stoage space for apps yeah?
i also still cannot find where the all apps shortcuts sit! (so i can rename/remove).
and lastly now i have the alpharev bootloader so gonna google how to change that
i did use the Leedroid apps2sd ROM. though most of my apps are still going to phone memory and i cant move them across.
Is there a fix for this? i guess once i work out how to delete these read-only files ill be ok anyway.
Unfortunately removing system apps wont give you more space to install apps, they are stored under a different partition, /system and /data are not on the same disk so you can save as much space on /system as you want but it won't affect /data at all.
With running out of space you have a few choices:
Go to settings..applications..then manage and move as many apps to SD as you can. This is fro-yo apps2sd, not all data is moved and not all apps can be moved, so you will probably run out of space again anyway.
Or
Reboot into recovery and partition your sdcard to create an ext partition, when you boot your rom ALL apps will be moved to the ext partition leaving lots of free space. Backup your sdcard before you partition it, you will lose all data.

1) Press on Remount as R/O, this should allow you to delete/replace system stuff & ringtones, fonts...etc.
2)No, because apps install to data/apps & not system/apps.
3)You mean like the applicatiuon menu when we used to delete shortcuts or rename them? Hahaha man that was sooooooooooooo long time ago for me. Anyway, the applications installed are displayer & you can't hide them or rearrange them like Winmo. You might want to try Launcher Pro to hide apps in the apps drawer.
If you need more info, ask freely because 2 years ago I went through the same

Hmm..actually the new MTD partition table hack should be able to free space on the /system, adjusting partitions with less for /system and /cache and more for /data/app should give enough space..Though I'm not sure if he wants to try this right now, since it's considered an advanced task and maybe he'd like to get more accustomed to Android before attempting it? His wish though..
And well, there's yet another method to remove system apps, other than the other two methods. This is to modify the zip file of the custom rom to remove the actual apks from /system and reflashing it on top of the actual flash..

Ohh yes indeed. OP, you can edit the zip before installing it to your device. You can remove/replace application in system/data and fonts...etc. Just remember to change signature verification to off in your recovery.
my god. i have spent days on this baby and im only barely scratching the surface
much appreciate all your help guys!
ok.. so its time to use app2sd i hear that app2sd+ is better though? (it moves more data to SD yeah? appcache?)
i only have 2Gb microsd right now so i might wait until i my 8GB arrives before i flash a new ROM and start again (again!)
i also noticed these online kitchens. http://cookmyrom.co.cc
which look great! tho they are still a version behind the leedroid i am using tho its a good way to get rid of some default apps.
i certainly like the idea of reparitioning the default disk though not quite ready for that yet especially when app2sd+ sounds much more straight forward.
i am dumbfounded that you cant remove 'shortcuts' from the All Apps! or even rename them!! my god. i would think that was first thing available on such an open source OS.
So i have now created a folder called "Folder" to reduce the clutter.. and now i guess i cant even rename it!?? and if i create another one its called "Folder" too!
lol.. this OS is so advanced yet some basic stuff seems to be overlooked.
I did try launcher pro though it removed my HTC Sense (which i like). So i might need to keep looking for an app to help organise my All Apps and my desktop (is desktop what its called?)
And just how do i add ringtones?
love your work guys thanks again.
Create a folder called Ringtones on the root of your SD to have...ringtones.
When you open a folder, long press on the header to rename it.
As for organizing, I stopped caring & started to use search, but maybe if you want you can try an app called folder organizer.

If i can have one last question. Any way to remap hardware buttons to start an app?
Like when you hold down the search button it launches Google Voice. I want it to launch a different app..
I did a search and found the hardware button remapper though it only does hardware to hardware.. not hardware to app
For Folders(Assuming you're using full HTC Sense), just open it and hold the title bar. Took me some time to figure out. You cannot easily rename the apps in "All apps", but you can remove them(Which is essentially uninstalling them) from Settings > Applications > Manage, unless they are system apps which need to be manually deleted either via S-OFF + Root explorer(OR something similar) or ADB + Custom recovery(Clockworkmod or Amon Ra).
For setting a custom ringtone, open the music app, select the music > Menu > Set as ringtone.
so no love on the hardware remap for apps?
Oh well i have done a lot of googling and it seems it cant be done (well at least not easily).
My last question is when you launch an app from a folder the folder stays open.. any way to force close or change its behaviour?
for those following this. I found the Tasker app remaps hardware buttons amongst doing amazing other things.
Still no love on closing folders though.
i ended up using tasker to create app widgets to replace the folders...
If you want app widgets, there's also "Desktop Visualizer".
In terms of killing of an app, have you tried "Settings -> apps settings -> development" then there's an option there for "stop apps via long press"?
I noticed some threads for different phones with regard to this but didn't see an answer for the EVO so I'll ask here.
I would like more space on my phone as I'm tired of seeing the little low space hard drive icon. I've already moved all the apps to SD via app2SD. I was thinking of installing the latest rooted stock Sprint ROM (3.70.651.1) and then deleting the stock apps that I do not use but I have read elsewhere that this will, in fact, not free up any more space for applications. Is this true?
If so, can I get a recommendation for the "most stock" ROM that's stripped of the Sprint added apps. If it has some ubiquitous and useful add-ons than that is OK
Thanks!
There's a couple of ROMs in the Dev section that are optimized for speed, and I'd recommend those. A lot of them have them already removed, but you can remove the ones that aren't
Thanks for the response... I apologize if I didn't state my question correctly. I understand that I can remove the apps that I want if I'm rooted, what I'm not sure about is if that space will be made available for other applications when I do remove the programs (in ROM) that I do not want.
Hope that clarifies the question.

A small amount of space will be freed. If you move Dalvik Cache to the Cache partition this will free up a lot more space than removing apps.

Thanks again for the info. I did as you suggested and now have 266 MB left where before I had less than 50. Using ap2sd with Azrael ROM and do far have not run into any issues. Keeping my fingers crossed.
Note, however, that most of the stock apps are in your system partition. The free space you care about for installing apps is in the data partition. So removing them doesn't free up the space you care about. Even on ROMs that have removed them, I'm not sure if they actually do (or can) resize the partitions to give you the space where it counts (/data).
You can, however, move apps to the system partition if you want. I've done this with some of the updates to stock apps -- GMail, Qik, and Flash, for example. That's freed some space up.

This sounds like it is worthwhile to learn how to do. Is there a thread or program that you could point me to for some guidance on how to do this?
I've also read that ap2sd can move programs that have not yet been modified to enable the regular android 2.2 "move to SD" function to work; but after flashing that app and using it to move the Dalvik cache I do see any obvious front-end for it.

Basically you just move the APK file from /data/app to /system/app using ES File Explorer (need to enable root mode in prefs) or Root Explorer. Or you can do it with adb or even terminal emulator on the phone if you prefer. I think Titanium Backup Pro (the paid version) has an ability to do this too. You also want to look in /system/app and see if there's an older version under some other name that should be deleted. Titanium Pro may handle this part for you automatically as well. I haven't bought it yet, so I'm not sure (though I plan to, the free version is great and the paid version adds some nice things). I think you can still get updates from the market after you've done this, but the update will go to /data/app. You'd need to move it and delete the prior version again after receiving such an update.
I haven't enabled a2sd yet. My understanding is that it's not so much something you need a front end for. Once you set it up, that's just where your apps go. You don't move your apps to the sd card manually. I could be wrong. I used whatever form of a2sd was available for XDAndroid on my old Touch, but that's been a little while and the DarkStar A2SD that people use might be a little different than that method. I haven't done it at all yet on the evo.
Thank you sir, that's very good info and I'll give it a shot.
Hello fellow I9000 users.
tl;dr - This fixes your low storage notification problems just by flashing it on CWM.
Disclaimer
First of all, I'd like to inform you that this post is a compilation of the work done by drafnel on the CyanogenMod forums, revthanki on the XDA-Developers forum, and as such I take little to no credit in it, as all I've done was ask for drafnel to help me in the cleanup code for me to put it in a flashable zip.

http://forum.xda-developers.com/showthread.php?t=1444333
Also, as you should know, you take full responsability should data loss or other kinds of damage occur.
Introduction
Lot's of people have encountered the problem where their /datadata partition fills up and then apps begin force closing. This is often confusing since there is usually a lot of space available on the internal 2GB storage partition. But these are two different partitions on cyanogenmod. The created the datadata partition on the fast internal memory so that apps would start up and run faster (i.e. less lag), but it is only about 170MB (which can't be helped).
One thing that can be done is to move the contents of /datadata onto the 2GB /data partition. That will solve the space problem, but then you have the lag problem. So, what we need is for the files that take up a lot of space to reside on the 2GB partition and the files that are accessed frequently by an app to reside an the fast 170MB partition. The files that are accessed often, or that affect app startup speed are the sqlite database files and the xml preferences files. These reside in the databases and shared_prefs sub-directories in each app directory. Drafnel has written a script to perform these operations.
Requirements
Samsung Galaxy S based phone (GT-I9000, Vibrant, Fascinate, Captivate, etc.)
Kernel that supports init.d scripts
How to use it?
As you would flash a ROM update or a Kernel:
Download the file to your sdcard.
Reboot your phone into CWM.
Choose 'install zip from sdcard', and choose the script from there.
It will run on boot everytime. It's pretty light so your total boot time shouldn't suffer. It will only do the operations if they are needed, and it will clean up after itself. No need to worry about broken links or stale resources.
What it actually does?
On every boot:
Runs a check to see if /data/data is still symlinked to /datadata/
Moves everything that isn't performance critical from /datadata/ to unlinked /data/data/
Cleans up old databases from uninstalled apps
Other stuff to watch out for
Titanium Backup users should tick the Preferences > Troubleshooting settings > Follow all symbolic links option
SlimICS users should follow this procedure
Changelog
11032012 - First working release.
LOL. I posted a request for exactly this script in the mintberry thread a few days ago!
Good work fella, Cheers.
OMG yeah! Was waiting for something like that . Will give it a try next time I'll encounter this problem .
Thanks mate.
Just flashed it. Cheers!

I had HUGE problems with Titanium Backup.
I lose all by backups some weeks ago because symlinked were corrupted after restore!

According to this post, you can now force TB to follow all symbolic links for backup and restore.
what if i already moved all my apps data to sdcard? do i move it back to internal memory then flash the script, or just flash the script then move the data to internal memory? which is the correct way?

Thanks! I'll try
AFAIK, if you have moved your apps to the SD card using the regular method (Apps2SD), the script will still work. This is because there's always leftover data on the phone, which then points to /.android_secure/ on the sdcard.
This script only changes the location of some data, but it's transparent to the phone.
If you don't feel safe about it, a full nandroid backup will restore the system to whatever setup you have now. (it also backs up what's mounted on the sdcard)
Well done! I knew I was never going to get round to this I'll close my old thread and redirect people here. Before I do so:
1) does the stock CM9 kernel support init.d scripts? If not stock kernel users will have to follow the manual method.
2) maybe it's worth putting a capitalised warning in your post to get people to set the option in Titanium Backup to follow all symbolic links
I flashed this script already but the low on space notification is still shown. It's definitely not working.
Do I have to create .nodatadata file inside /datadata and reboot now?
Sent from Ice-Cream flavored SGS GT-I9000 using Tapatalk
Free space in datadata folder,
Before flashing the script = 25mb
After flashing the script = 146mb
Definitely works without any lags.. one might experience lags on the first boot but after another reboot all gonna be super smooth like before!
Thanks a lot!!
It deleted some of my apps like Dolphin HD. I'm running CM9, with IcyGlitch Kernel. Oh well, restored.
Gr8 work
Many Thanks,
i have been waiting for this script ever since Darktremor Apps2SD (2010 !!! )
thank you!!!!!!!!!!!!!!
Great Job!
Excellent, it's very smooth like before, thanks a lot.
aha! that's the reason why all my apps suddenly began to lag like hell and some time after that force close. had only 1MB free space on /datadata partition lol. script works like a charm! thx

I heard some kernels don't load init.d scripts on ICS, might be related to that.
finally......
before script 11mb and after got 168mb free space! thanks!

I am super-curious if & how anyone here is using Link2SD successfully with CM11 (on the Epic 4G, specifically).
I've tried scouring these forums, and the Internet in general, to figure out the best way to get this to work...
But everything that I've tried, it all seems to be working great, only up until the first time that the phone reboots, then it all goes to hell.
I am wondering if there are any extra steps to follow, specifically for the Epic 4G, or any particular pitfalls known to avoid?
That's why I wanted to ask here, specifically to Epic 4G users...
If you are getting Link2SD to work well with CM11, then please chime in here, and can you explain how you got it all set up and working well?
(I feel like this is the one last thing that if I could conquer it, then I could really continue to get a lot of life out of this phone... as it stands, it seems too risky to put much faith in Link2SD, because if the phone happens to spontaneously reboot while I'm out running around, then I'm screwed because so many apps just disappear, and then it's a pain to re-download, re-install, and re-setup each of them...)
Thanks in advance for any help,

I am using Link2SD on my Epic 4G with CM11 with some success. I just did a reboot, and as usual lost any icons that had links created in Link2SD, so I go to the app locker & re-add them to my home screen. This is typical of what happens on a reboot for me. One thing I did notice is that it takes a minute or so for the deleted app icons to show up in the app locker again, so if you are reinstalling them, it may be a matter of waiting for them to show back up. Also on occasion(not this time), Link2SD will prompt me about a problem with the links and then prompt me to reinitiate the partition or something to that affect. Once I do that and it reboots, the app icons are still gone, so I just re-add them. Anyway, I know its not a perfect solution, but with this device its better than running out of RAM. One last thing, needless to say, I only create links for enough apps to free up enough RAM to keep my Epic working properly.
I've finally got a system going that seems to work for me, and so I thought I'd share some things.
I'm on CM11 (as of today, cm-11-20140602-NIGHTLY-epicmtd.zip) and I'm using Link2SD.
HERE'S A "GOTCHA" THAT HAD ME PULLING MY HAIR OUT FOR AT LEAST A DAY OR TWO:
Link2SD was having problems mounting the 2nd partition - it would just say "Mount script cannot be created." or something like that (not a very helpful error message), no matter how many times I rebooted and tried again. What I *finally* figured out (somehow), was that this error was being caused by /system being completely full. When I went and deleted a few things from /system (such as goofy wallpapers or that 'Apollo' app that I never use), then Link2SD was able to successfully create the script, and then I'd reboot and could use the 2nd partition successfully.
It's still a little aggravating that any reboot of the phone will cause all of my "Linked" apps to disappear - I've played with this until I am blue in the face, and have resigned myself to accepting that this is just "how it is" (?) - but I'm now using Titanium Backup as my workaround.
STEPS I TAKE WHEN THE PHONE REBOOTS:
1) Go into Link2Sd and make sure the 2nd partition is usable, otherwise recreate mount scripts (deleting wallpapers/Apollo if necessary)
2) Under Link2SD's "More" menu, perform the following:
a) Clean up the 2nd partition
b) Clean up the dalvik-cache
c) Clear all app caches
3) Restore apps from Titanium Backup
a) starting with Facebook app (the biggest hog) and then immediately go and make Facebook a "Linked" app again
b) restore a few more apps (to internal/phone), then go and shuffle those over to "Linked" apps via Link2SD
c) (repeat step 'b' until all apps are restored and "Linked" via Link2SD
^ This is the only way I've been able to get this to work for me... but now I can put about as many apps on the phone as I'll ever possibly need, and I have to say everything is running pretty smoothly now - but if anyone can see a better way, or how to improve what I'm doing, then I'm all ears... please let me (us) know.
Thanks!
Apex launcher doesn't lose the icons. I can free about 66MB of system space by swapping the launcher, deleting CM wallpapers, live wallpaper and Google keyboard.
I verified link2SD plus was not working properly but free link2SD works as advertised. For me, just installing the plus version will break the working functions of the free version. The free version scripts, links and launcher icons survive reboots. The plus version continually lost mount and wouldn't properly clean up the second partition and was not copying the lib files and placing them in the second partition.
Edit: per the developer's request, after verifying free link2SD was setup and surviving reboots, I added plus link2SD and rebooted: OK so far. Next I linked a file with plus version; OK until reboot. The application was not found except in directories. Dalvik cache cleanup finds the dex link and file in second partition as unneeded files. Had to manually delete all the files and links for the broken application and reinstall it. Also had to uninstall plus link2SD to properly link again. Sent the results back to developer.

Edit: 6/20/2014; link2SD 3.4.8 fixed the reboot issue for the link2SD Plus version for me. Sent email to developer to thank him for the fix.
See post #8.
Update on my last entry:
I emailed the link2SD developer and got a reply asking me to check the plus version again. In my reply back I linked him to this thread.
Another tip to add for nightly flashers that use link2SD and modify the zip prior to flashing: pull the mount script, 11link2SD, found at /system/etc/init.d and move it same location on zip before flashing. If retaining data, ie: dirty flashing; the mount securely retains your apps after flashing new nightly. Just checked with free version of link2SD: works.

I'm using link2SD for all minus 16gb internal android device. Here is what i do in epic 4g, currently on CM11 20140523, use 20131209 gapps. I just write the part involved link2sd :
1. Buy atleast 16gb microSD and class 10 is a must, make 2nd partition (usually about 4gb - 6gb) as ext2 - ext4 (depends on the OS).
2. Device rooted, install titanium backup & root explorer 3.1.3 (make sure the root explorer working). Uninstall system apk (one of the launcher, whisper push, terminal emulator (I prefer use better terminal emulator, install as user app), CM filemanager, etc - still more that can be uninstalled for more space in system.
3. install link2SD, pick ext2 - ext4 (depends), dont restart yet. go to setting, uncheck everything then restart.
4. After back to launcher, open root explorer, go to root/data/, check app & dalvik-cache folder, press copy. Go to sdext2 folder, delete lost&found folder (usually there), and paste. So the app & dalvik-cache folder is there now (you could copy data/data folder too if you really want maximum extra space in internal, but in epic 4g i didn't copy data folder because it's enough space).
5. At the sdext2 folder, long press app folder, select "link to this folder", go to root/data/, press "create link" - "yes". Then go to sdext2 folder again, long press dalvik-cache folder, select "link to this folder", go to root/data/, press "create link" - "yes". Do the same if you copy data/data folder to sdext2 folder.
6. Reboot. Done. Then installing others app or restore with titanium backup.
I hope this is useful. Some Screenshot attached.
Hello
Thanks for that solution.
I`m searching for this solution since 1-2 weeks.
I had the same Problem on xcover 2 Link2SD.
Now it`s clear i have installt Link2SD and works perfect for just 3-4 days then i upgrade to Link2SD plus and then it happend like the Threat above.
I`m wondering that Lin2SD works perfectly on CM11 and if you go to Link2SD plus for money and this don`t work.
Free works perfectly and paid work not.
I have go back and everything its fine.
I hope the autor will fix the problem then i go back to plus.
Thank Thanks Thanks works fine!
regards marle.m
Good news! It appears the link2SD version 3.4.8 released today has a bug fix to survive reboots for linked apps when linking with link2SD plus version.
So far, I've only linked one app with plus version enabled and it survived one reboot. Then Ⓘ linked the data folder and rebooted again which also survived the reboot.
Looks like plus version is fully functional; I'll update if it fails some time later.

Finally had a chance to sit down and mess with this...
Yeah! Success! Freeing up space in /system worked.
Next question...Will I have to remove the bloat prior to flashing from now on? ie no more CyanDelta easy flashing
Anyone have any Scripting-Fu to come up with an automated method of stripping out said bloat?
thx sno

I was thinking the gapps could be modified at the updater-script to remove some system bloat. Then remove some bloat from that as well. Most remove their own bloat choices so maybe a diy tut would be more useful?
I agree, the script would make the nightly flashing easier.

Just realized that if using Link2SD Plus to multi link all folders of an app to sdext2 after a clean install is still broken, if using intended method. Apps linked this way are missing after reboot.
Working on a safer suggested method that focuses more on removing apps from Gapps but also removing some other system apps after flashing a nightly that requires no modification of the nightly zip on a computer. Have to focus on linking only a minimum amount of apps with free Link2SD considered less risky to move, like larger stand alone apps, not needed tools.
I've got a working script and method that works but the risks to be avoided need to be detailed along with the tut to script and tool your own modified Gapps that minimizes the flash to flashing the nightly as-is and then flashing a custom Gapps that includes preferred launcher and restore methods.
Removing CMWallpapers, Apollo music and Trebuchet launcher. Substituting blacked out Google play. Replacing removed apps with Apex beta test launcher for test group, blacked out Pandora (these will be installed at /data partition where they can be easily uninstalled or updated) I use my own borrowed wallpaper.
Along with the removed bloat from Gapps, this frees a bit more than 40 MB of system space.

UPDATE: the latest version of Link2SD (3.5.2) has "fixed the bug that causes linked apps disappear on reboot when internal data is linked".
So... if you've also ponied up the buck or two for Link2SD Plus (as I have), then this finally works again like you'd always hoped it would.
I just loaded a bazillion apps back on the phone, and have been able to reboot multiple times without losing them.
The only time I "lost" them for a moment was after flashing to the latest CM11 nightly, but then doing the "Recreate mount scripts" and reboot brought them right back, with no other shenanigans necessary.
(Just wanted to let people know, because this is such a relief to me now....)
HURRAY!
OK I'm trying this again. Reboots are fine as long as I don't select quick or soft reboots; I lose mount, linked apps not installed.
Now need to try the clean install of nightly.
