Is it possible to change partition sizes on Arc? - Xperia Arc Q&A, Help & Troubleshooting

Now that i've finally gotten around to unlocking my bootloader & playing around with custom ROMs, i'm wondering if it's possible to resize the various partitions in the arc's internal storage, to reclaim some of the now unused space in the cache partition (since youre not going to be doing OTA updates on a custom ROM) and the system partition (if you install a cut down/minimal ROM) for apps.
On other phones (e.g. HTC Hero, HTC Desire) it's been possible to achieve this for quite a while now. Had a look around the arc forums but cant see anything that even hints that this being looked at for the arc.
Is it something that nobody's got around to yet (the arc is obviously newer than either of the phones mentioned above, and there are a lot more phones about now, diluting the pool of available geniuses to work on this sort of thing), or is there insufficient information available, or is there something about the arc's hardware that makes this fundamentally impossible?

I am pretty sure this is protected and can't be touched, although Sony allowed the bootloader to be unlocked they still keep some things locked.
I am not a dev so maybe proved wrong.

I can remember that when arc was new on the market, some devs tried changing partition sizes for CWM, and they bricked theyre devices with it.
so yes repartitioning is possible, but i don't recommend you doing so cause doing it could totally brick your arc

Not to much, what can you do is, link dalvik-cache to SDCard.

We could reclaim about 250MB of space!!
Some devs know how to do it for sure. As they do it for x10.
Flashtool devs should be your targets.

Bumping up this question. Is there no working way to do this after many months? Say for my Arc running on Arconium 8.2:
System ROM : 419 MB (201 MB free) = 620MB total capacity
Internal : 440 MB (118 MB free) = 558MB total capacity
Overall TOTAL : 1,178MB
DESIRED:
System ROM : 419 MB (77 MB free)
Internal : 440 MB (242 MB free)
Basically reduce the overall system ROM capacity from 620MB to 496MB, and the free space given to Internal (558MB to 682MB). The overall total remains the same of course.
Any way to do this? Or I am basically stuck at converting user app to system app in order to maximize the capacity?

I don't think that would be possible... Try rooting your phone and install clockwork mod... In tat you could partition your sd card say 500 mb and make it as internal memory via link2sd... Search in arc forum...

Your first calculations are wrong. System ROM has 201 MB free out of 419 MB, and Internal has 118 MB free out of 440 MB, so max is 419 + 440 which is 859 MB. The 1000/1024 difference, you get the 1000 MB of flash memory (hardware) on your phone.

That's correct.
Table can be changed if someone can break Sony's encryption keys.
My HTC Desire runs on changed partition table (cm7r2).

i see, thanks for pointing that out. in any case, i can't do anything but do convert to system app to maximize the usage.

there is not a benchmark thread because most chefs post the bench scores in the roms own thread, this is probably how it needs to be done for android as well.

Sorry for not posting sooner but i'm not sure where the app is doing the test read/write, and until i find that out i don't know if its a useful result, because if its writing to the sdcard then its just the speed of the sdcard itself rather than xfs on the root and data partitions showing the performance boost. There is also umounting issues with xfs, which means it has to be cleaned on startup, Its log is causing lots of extra writes to the sdcard which will shorten its lifespan.
The current method of storing data in the data.img is fine, the only issue is that its in data.img in the first place. I'm frequently messing with my system.img, rootfs.img and data.img and it became time consuming and i had to run lots of commands, i used xfs so that i could just mount the root partition and edit it directly rather than editing the system-cupcake-03 folder, then using cramfs, then mounting the sdcard and copying over the system.img, i hated doing stuff this way, too many long commands.
Its very very very very annoying to have to create a new compressed image just to change a single line or use a new thing, so i wanted everything as a partition and thats how xfs as root and data came about.
[ /sdcard - rest ][ 300mb rootfs.img+system.img combined ][ 200mb data ][ 64mb swap ]
It might be faster with ext2 as root since it doesn't have a journal to write along with the written data but i've always used xfs on my server so i went with it

I would also like to know how you set this up. It is very annoying having system and rootfs has RO, and I would imagine that it slows everything down considerably to have to compress and decompress all the time. You using a custom kernel to enable support?

Then you can create a system.ext2 image and use it rather than the squashfs files. I think rootfs rw, just the system is ro.

If it is that simple, then why is everyone using *.img and *.sqsh files?

Well .ext2 images are much bigger and so it'll take much longer to upload those. Also there aren't any benchmarks of the performance difference between squashfs and .ext2 system images. But the issue is this, reading from the sdcard is slow, if its compressed you'll read less and uncompress it, and uncompression is pretty fast. It could mean that overall squashfs is faster than ext2, so without a benchmark i think squashfs is fine.

cross platform?
Hey now everybody.
So this guy I know got himself an HD2 maybe to spite me for buying an N1 and defecting from WinMo. He's talking a lot of trash, won't relent. Me too.
I'd like to engage him in a drag race and I think since we're talking about two very different platforms the simplest way to do this is just to pit how our respective operating systems handle the Snapdragon against each other by means of a Pi fight.
Maybe this isn't the best place to ask but off hand anyone know of a WM equivalent to something like BenchmarkPI or anything else there may be to standardize something about our phones related to math? Or perhaps there's a better way to make my point other than going back and forth about milliamp hours, weight, the virtues of hard buttons and Google versus Microsoft?
Thanks.

everyone knows you can get different speeds based on different browsers.
But the real question Doug, is what resolution is that nexus? Rumor has

{PRO} after installing CM 9.0 its showing less ram?

Hi, like in topic - i've at last installed CM 9.0 FXP 130, but when i enter system info its showing only 360MB of ram, instead of 512 (SEX PRO got 512 as far as i know).
Why is that happening? Is this bug, or i don't know something?
I think you can allocate more RAM to your phone...
That's not bug/issue. 360 mb is user-available from 512

Recommendation for ICS And all other GB Roms

Guys I think everyone tested ICS 4.0.4[BETA6] ,well there are a lot of bugs yet to be solved (thanks for Team PECAN) to do such a good job .well incresing RAM memory is not a big issue i think you all know it but still iam posting this thread so that those who are using this ROM for daily use may not have any problem related to RAM uses .
So by this tutorial you can increase your ram memory
Requirements : 1) Swap it ram expander which i think u can download from 4shared.com - free file sharing and storage
2)Free memory in your SD card upto 2 gb ,well using swap it 2gb is the maximum limit for increasing ram (yeah u can expand your ram upto 2gb )
3)well as we know Rooting and all stuff so iam not writing about all these things .
Steps
1) First of all install Swap it ram expander
2)now open application and in my case i gave 512 mb for expansion u can give upto 2 gb as your wish
3)then tick Swap active and swapiness 90
4)u can tick the Autorun option too if u want to use it after reboot and all stuff (well who doesnt want that )
5)Download Link SWAPit RAM Expander v1.2.1.apk - 4shared.com - online file sharing and storage - download
well after these steps you will get notification that swap it is running !!!!
ENJOY
After performing these steps you will be able to get 72 mb of free ram in ICS which is good enough .
If any how i helped you Press Thanks !!!

[Q] Advices to speed my phone

Hi guys, i would like to know any advice to improve the speed of my Xperia Play. Sometimes i got lags and when i play heavy games like Max Payne or GTA it reboots. My phone settings are:
Stock GB rom 2.3.4
Lupus v5 kernel
Xperia Mix theme
Root and unlocked bootloader
No frills CPU with min. frequency 245 MHz and max frequency 1,2 GHz
Stock micro SD card with a second ext2 partition of 2gb and 6gb of primar partition (4gb occupied and 2gb free)
Internal memory: 169mb free
Ram memory: 120mb free
Can anybody give me some advices to speed the phone, without changing rom or changing the stock rom with another GB rom liveview-compatible?
Thanks in advance!!!!
Your already running stock with a good kernel. Only other thing is overclock it more and maybe get a faster class 6 microsd. And change your i/o scheduler and cpu governor to a more performance based one.
Use a program like LBE Security Master to block programs from auto starting and clear ram before you start the game.

LG G Pad 8.3 (V500) - is it worth to resize system partition?

Hello everybody
Currently my system partition has 2113 MB (it is default size), I have CM 13.0 installed with OpenGapps Pico package on it and only 988 MB is used so it's means that 1125 MB is free. I wonder if it is a good idea to resize this partition to e.g 1113 MB and shift all free 1000 MB to data partition? What's your opinion? Does anyone tried this?
best regards,
The question is "can it be done"? Usually resizing partitions is quite difficult and may brick your device.
hmmm... I didn't think about it like that. I thought that I can resize as I want but I have to keep big enough to put ROM on in.
