[NEED HELP] Help with update-script

I need to copy a single file using an update-script (update.zip's script)
I know that command to copy a dir is
Code:
copy_dir
But if i want to copy only a single file how can i do?

put only a single file in the dir? not sure i get your problem, the script should copy everything from the update.zip to the flash memory, why would there be a need to copy a single file?

Kendon is right. Just
Code:
show_progress 0.1 0
copy_dir PACKAGE:system SYSTEM:
show_progress 0.1 10
is needed to copy a single file into the system directory. That script is from one to install WaveSecure to ROM. All it does is copy the contents of the system folder (which is a folder called app, to that location on the system partition of the phone. As there is only one file in the folder app, that file is added or overwritten. Nothing else is changed.

No, i need to copy only one file form SYSTEM to DATA
Then format SYSTEM and recopy that file from DATA to SYSTEM
How can i do?

i don't think this is possible with update-script, as it wasn't made for this purpose. care to elaborate what your main goal is, maybe we can find other ways?

[KERNEL] Universal external lagfix (btrfs,jfs,ext4,reiserfs)

This lagfix will mount /data /dbdata /cache on your external SD almost whichever
FS you choose.
You must partition your SD with 4 partitions in this order:
primary FAT32 (size you wish)
primary your_FS 2Gb for /data
primary your_FS 128Mb for /dbdata
primary your_FS 30Mb for /cache
Supported filesystems are btrfs, ext4, jfs, reiserfs
Sizes are given as indication
This kernel mounts filesystems noatime,nodiratime
Kernel includes busybox full and su. adbd starts at boot by default.
You can even mix and match FS like reiserfs on dbdata, ext4 on data and jfs on cache
How to do:
1: partition your external SD appropriately and format it (using i.e. http://partedmagic.com/)
2: flash zImage_0.1 as kernel with Heimdall
or alternatively flash zImage_0.1.tar with Odin
Kernel can be found at http://llorien.org/samsung_galaxys/jpm/universal
This will obviously wipe your data, if you don't copy it first.
I only tested this on the international Samsung Galaxy S GT-I9000 running froyo JPM.
NOTE: Do not flash unnumbered versions
If you want to revert back to the normal behavior, just flash a stock jpm kernel and you should be fine.

Well, this seems very promising.
Thank you Nikademus.
+1
What do you mean by unnumbered versions?

And what about battery life on HD2 if filesystem is on SD it drains more battery?

Can you somehow make this automated? Not a lot of people here are on linux & repartitioning is not really everyone's cup of tea.
Thnaks.

Some bugs:
1.Tried o flash zImage_0.1.tar and that did corrupt the phone system, so beware!!
The zImage in the tar file is named zImage_0.1, it should be named zImage (more on this later).
2.Extracted zImage_0.1.tar and renamed zImage_0.1 to zImage and added it to a tar file using 7-zip and tried using Odin, that did not work, Odin would hang on flashing zImage.
3. Downloaded zImage_0.1 and renamed that to zImage and flashed using Heimdall, this worked, but the phone seemed to continue scan the external SD-card.
4. Powered down the phone and did a cache wipe and a factory reset and rebooted the phone, it booted but then got to a black screen with the return-key and menu-key on all the time.
The card was partitioned using Partedmagic in external card-reader.
Will try again now and report back.

eclair or froyo ?
hi
Can't read anywhere.
Is this lagfix for eclair rom or froyo ?
It seems the mounbt point of external sdcard isn't just the same on those roms.
Op, could you make the light, please ?
Thanks

That is planned, although you will probably have to put a config file somewhere to define filesystems you want.

Did you format the filesystems?

@nikademus
Here is the deal...The zImage_0.1.tar that can be downloaded from the link you provided is not a tar file but a Gzip file, when extracted then there is what appears to be a file named zImage_0.1, this is not a file but a tar file, that is missing the tar extension, by adding the tar extension, i.e renaming it to zImage_0.1.tar then it can be flashed using Odin. The majority of us are using windows, and some of us are using Linux and OSX where these archives might be read right by the operating system, but in windows it can only be checked by using winrar or 7-zip.
I'm not a novice Windows or Linux user, I know enough, and offcourse I did format the 3 partitions as jfs.

Well, I don't know how you have got a gzipped file but I can ensure you that the tar file is a real tar file. I don't use windows at all, so it's a little bit hard for me to test on windows to find the reason behind this.

@nikademus

Details when the zImage_0.1.tar is extracted:

He's right. Although it's strange that "tar xvf" would extract without the z option (pipe through gzip), but if you rename the file to .tar.gz, then gunzip will work on it, and more importantly, 'file' identifies it as a gzipped file:
[email protected]:~/Downloads$ ls -l zImage_0.1.tar

then, rename to .tar.gz and gunzip, and identify again:

Thanks, at last
I was trying to point out that the file can be flashed by Heimdall but not by Odin, Odin can only flash tar files, if you flash the file in it's current stat then it will corrupt the system and when the majority here are using Odin this should have been taken seriously, but it appear that it does not matter, unless a member reporting a bug has been spaming the forum and has a load of posts to backup his words.
I'm done testing this release...good luck.

Well, I must admit this is quite strange because this is not gzipped. Which program did you use to download the file? I would say it's probably because the web server compresses pages using gzip to reduce bandwidth and the program who fetched the file did not uncompress the file like it should have done.

I used Google Chrome on Ubuntu Maverick x64. I'll try wget and see what happens, but that's an interesting thought regarding mod_gzip or whatever the apache extension is called.
Regardless, perhaps it would be best to supply a .tgz instead? What's the point in tar-ing a single file ? The idea of tar is to pretty much concatenate multiple files into a single file, without compression, isn't it?

Because Odin only understands .tar format. If you run from linux, just download the zImage_0.1 with tar, you can flash this one with heimdall

Ah, fair enough.
Strange then!

BTW, "tar xvf" *does* still work on the apparently gzipped file. Which is weird. Unless GNU tar is just being 'clever' by detecting the gzip compression..
At first I was just looking at your output from before where you did tar xvf, but I just tried it myself on the supposedly gzip file. Weird.

[03 JAN][IDEA] Ramdisk for CM6 builds with external data.img [NOT BUILD]

Features
- external data.img support.
- update kernel and system files without adb.
- easily update build with update.zip, don't have to re-flash.
- options to set data.img size, lcd density, etc in config file.
To enable external data.img
1. create '.data' folde under sdcard (/sdcard/.data).
2. create 'config.txt' under '.data' directory, add 'data_img=1' into 'config.txt'.
3. copy old data.img to '.data' directory, otherwise a new data.img will be created.
4. boot into Android.
If experiencing issue with 1 and 2, simply copy '.data' from View attachment data.zip to sdcard.
To disable external data.img
- delete 'data_img=1' in config.txt.
- delete config.txt.
To change kernel and modules
1. create 'update' folder under sdcard (/sdcard/update).
2. create 'boot' folder under 'update' directory, put zImage into 'boot'. (reboot is needed after updating)
3. create 'system/lib/modules' under 'update' directory, put bcm4329.ko, tun.ko, etc into 'modules'.
4. boot into Android.
To replace initrd.gz and system files
- same as change kernel and modules.
- put 'initrd.gz' under '/sdcard/update/boot'. (reboot is needed after updating)
- put system files under '/sdcard/update/system'.
To use update.zip
- create an update.sh and compress it with update files to update.zip.
- put update.zip under 'sdcard/update'.
- Try ClockworkMod Recovery for HD2
Downloads
- View attachment leo-initrd-0.1.1.zip
- if you want to test the ramdisk, download this build package. Don't forget to backup your data. (thanks to projection for the kernel)
If you've downloaded LEO-CM6.1.1-NAND-3.zip, to update to 3.1, please download the new initrd file, then try the update method above.
To do
- add desire builds support
- add squashfs support
Changes
0.1.1 - fix a stupid typo, sorry.
0.1 - initial.
About config.txt
Code:
data_img=0
- 0, default, use nand userdata, about 250 MB for cm builds
- 1, enable external data.img support (/sdcard/.data/data.img)
data_size=512
- size of data.img, only work when data.img support enabled and first install
data_sync=1
- 0, fast, default, disable sync option when mount data.img
- 1, safe, enable sync option when mount data.img, use this if experiencing data corruption
lcd_density=240
- size of icons
gps_zone=us
- country code, us, fr, jp, etc
Credit to DarkForces Team and everyone in this thread.

that will be very usefull one.another massive milestone in android-hd2 development.cheers

I'm just downloading RAM DISK build... why You strike it ? shoudn't I install it ?

it is becoming obvious that this will be essential for euro H2 NAND builds being that there is very little phone space to play with, where this would be best cooked into ROMs more detailed instructions for noobs would be good.

This is a great idea and will help with the euro versions of hd2 with limited space.
I wonder what will happen with sync, will we run into data corruption problems as with sd builds?
Can this be made so as the data can be on a seperate ext 3/4 partition in sync and the rest of the sdcard can be mounted / unmounted etc ?

Please download later since it is not available right now.
The lib and xbin is compressed with squashfs in v2, so you can't edit. That's just for test propose. And squashfs file systems have been removed in v3.

great idea
Is it become to HD2NAND?

I'm new to Android builds configuration, but after some research it looks like it's possible in theory. Personally I do not understand why everyone is so obsessed in data.img file, while it's linux partition in file, that stored on FAT partition. I think actual linux partition on sd card is more elegant solution.

Why I use .data instead of data or data2sd? Just want to keep it hidden.

[Cuestion] Swap Partition on CyanogenMod 7.2

I tried every way, but I can not use the swap partition on my WFS.
I installed the latest version of the ROM and the Kernel, but I can't make it work.
Does anyone know what should I do to run the "Swap Partition" on my phone?

Go through this.
http://wiki.cyanogenmod.com/wiki/Swap_and_Compcache
The cyanogenmod team feels that swap doesn't serve it's purpose on an Android device. To quote them
"This question is hotly debated, but you almost definitely do not need swap or compcache. The only exception to this may be if the device is a first generation device (i.e. HTC Dream or HTC Magic). If you think swap or compcache may make the device faster, feel free to follow the directions below."
Click to expand...
Click to collapse
And the WFS is not a first generation device
If you still want to go ahead with it, that link provides a how-to.

But the problem is that with this ROM my phone does not recognize the swap partition. I would like to post on its own thread, but I can not because I am a new user.

You have to create a mount script and copy it to /system/etc/init.d and give it the same permissions all the other files in init.d
Attached is the code to use if you have swap as the third partition on your SD card. Remove the .txt extension and place it in /system/etc/init.d and give it the appropriate permissions then reboot
Use the command "free" in a terminal session to verify swap is active and working.
It should be pretty straightforward to modify it to be the second if you aren't using an SD Ext partition for programs.
The code is:
Code:
#!/system/bin/sh
#Checks for a swap partition on mount 3 of the SD card and use it for swap partition.
if [ -b /dev/block/mmcblk0p3 ];
then
#Uncomment the line below to adjust swappiness. Default is 60 I believe
# echo 20 > /proc/sys/vm/swappiness;
swapon /dev/block/mmcblk0p3;
fi;
Change the line:
if [ -b /dev/block/mmcblk0p3 ];
to
if [ -b /dev/block/mmcblk0p2 ];
If you only have your FAT32 Primary and your Swap partition and no SDExt

I will try it this evening. Some people told me that oboe is that I created the Swap Partition with the recovery and I have to create it with the PC.
If I get it working I'll post my results. If not you will see me here again.

You have to mount system partition as RW to be able to manipulate with files there, big white button "Mounr R/W" in the upper part of the Root explorer app while you are in /system/etc/init.d folder. Then you put there swap.txt file that d33ps1x provided up in the post, rename it just to swap and reboot phone.
I did that with almost every version of cm7 from the begining (in which kernel allowed that) and every time it worked, tnx to d33ps1x

Then the problem can be with kernel on ROM you are using, basic thing is that kernel needs to be abble to support swap for swap to even work... Can't help you much there since you are probably on marvelc version according to you'r country flag, i'm on diferent version. Some1 with same model as yours could help you tough

Is there any way to install another ROM that support swap? which ROM should I use? is there any tutorial?

The [2nd] above post is correct. Swap support is enabled in some custom kernels. If you're looking for another ROM, you're going to primarily ask about the kernel included with that ROM. Stock kernels do NOT support swap. You can enable swap [if you have a supporting kernel] via A2SDGUI or terminal... read up and familiarize yourself with linux swap.. since Android is a branch of Linux; same principles apply

This says it's possible to enable swap and compcache on CM7.2, but the howto wiki link is dead
To answer you question directly, by default the swap and Compcache schemes are disabled, but if you still feel the need to use them, above link provides you with a how-to.
So, yes, the CyanogenMod 7.2 supports swap and its usage needs to be activated.

Any idea how to do this?

For me the same question. I'm investigating since 1 week, tried scripts etc. no chance
Nexus One,
4EXT recovery (needed for correct sd-ext formatting)
CM 7.2
swap partition is there but not used.
What could i do to enable the swap partition?
Regards,
Marc

Hello,
I have the stable release cyanogenmod 7.2.0.
Swap is not working and gives following message:
swapon: /dev/block/mmcblk0p3: Function not implement
I found some notes saying that the problem is the kernel not supporting
swap. Which kernel can I use with cyanogenmod 7.2.0 with swap support?.
Thanks for your help.

[Q] Mounting Stock ROM system.img on W7/8/Linux to view and copy files

- I unzipped e.g. T705XXU1ANF from samdownloads.de.rar.
- Then I opened the T705XXU1ANF7.tar.md5 and extracted the *.img files with winrar.
- Then I tried to mount system.img / recovery.img with OSFMount.
Mounting worked but non of the ext2 tools (Ext2Fsd, ext2explore, explore2fs-1.08beta9, Paragon ExtFS for Windows, LinuReader ) would recognice the mounted image or could mount the image itself to view the files.
For ICS/JB I read about ext4_unpacker. Do we have something like that for Kitkat ? Or is it possible under Linux (I am a noob there)

Basically on Linux, it's really easy.
mount -o loop disk1.iso /mnt/disk
Or wherever that you want it to be.

did one of you mount an system.img from Kitkat Stock Rom already ?? Because I dont think ist about W7/8 .... some of the tools listed should be able to read ext4 ... (ext4_unpacker wont work either !!)

no it cant be mounted that way... I tried under unbuntu LiveDVD. the System.img can be mounted, but there is no readable filesystem. So it must be processed in some form like ext4unpacker did for ICS/JB ...

You're right... I thought it worked out of the box.
Anyway, I used RKwinTools to extract the system.img contents on Windows.
Place system.img in RKwinTools_v133\unpack\firmware\image\
Run the batch file and select option 6 and you'll find the contents under RKwinTools_v133\unpack\System

THX unpacking worked like a charm, but is there also a way of just converting the img to one that is a mountable.ext4. This one I could use under Win and Linux as it would keep permissions ... (Simg2img didnt work)
This is the error:
Code:
*** Please wait... ***
Ext4Extractor version 1.5.2 Created by And_PDA Based on sources ext4_unpacker

Well option 7 will convert the sparse ext4 image to a normal ext4 image. The message shows error but it would seem that it's converted. Find the image in the same location that you placed system.img.
Mount system_ext4.img on linux using
Code:
mount -t ext4 -o loop system_ext4.img /mnt

THX so far, I can mount it on my Linux PC not under Win8
- Linux Rader still cant open it
- I can Mount it with OSFMount, but neither paragon ExtFS nor ext2Mgr recognice the mounted Drive ????

ideas very welcome
