[WIP] Recovery for Arc [Devs invited]

vegetaleb · Apr 21, 2011

Ok now that we got Root on Arc thanks to our devs (Bin4ry...) it's time to move to the next step...recovery!
All the devs who want to discuss, brainstorm, work on and edit recovery for Arc are all invited here.
I don't consider myself a dev so I will let you begin...

Can you check which
/dev/input/eventX [X is a number]
is the Keys under the display?

On X10 it's
/dev/input/event2

f.e.:
You can try it with:
cat /dev/input/event2

now press the keys, do you see some output? If not just try the next one. Until you find the right one for the keys.

Regards

On mine (unbranded, unlocked, UK version) it's /dev/input/event1

Bin4ry · Apr 21, 2011

Okay,
Flashtool is already prepared for this case!
So we can try it directly. Download latest!!!!! Flashtool (version 2.9.1) and download the chargemon.zip from my attachment.
Flashtool link:
http://xdaforums.com/showthread.php?t=920746

Unzip the file and copy it into flashtool folder:
Flashtool/custom/xRecvery/
overwrite the original chargemon file!

Now open flashtool and and click "Ask Root Permissions", if that had worked you will see that the "xRecovery" Button on the right side gets activated.
Push it now!

When flashtool says -> Recovery installed.
You can reboot the device -> Now push the back button on the device during the booting process. If all works you will be in Recovery

Flashed the recovery, but it doesn't appear to be loading (tried rebooting while holding the back button, and 'adb reboot recovery')

Bin4ry · Apr 21, 2011

adb reboot recovery won't work!

try opening flashtool ->Advanced -> Recovery -> Reboot in recovery.

Does this work?

Regards

chriscpritchard · Apr 21, 2011

Nope, didn't work!

Bin4ry · Apr 21, 2011

ok, thanks for testing.

Can you check if the files are there correctly ?

use adb shell and type:

cat /system/bin/chargemon

do you get a readable text or some weird signs?

Regards

chriscpritchard · Apr 21, 2011

Strange symbols

chriscpritchard · Apr 21, 2011

As an update - I copied the correct version onto the phone (the script) and it still does the same thing

Bin4ry · Apr 21, 2011

Okay thanks,
maybe this will help.Problem is that we cannot run anything from /data/.....
So Flashtool fails to install it :/

Just run the RunMe.bat

File seems to be missing 'sh'. Also, getting permission denied when attempting to copy into /system/bin. (/system/bin permissions are root:shell, 755).

chriscpritchard · Apr 21, 2011

you're missing a file ("sh") and the adb push commands failed - I modified your batch file slightly, but it doesn't work, possibly due to the missing "sh" file

Code:

adb shell su -c "mount -o remount,rw /dev/block/mtdblock0 /system"
adb shell mkdir /system/recovery
adb push files\recoveryLT15.tar.bz2 /sdcard/arcrecovery/recovery/recovery.tar.bz2
adb push files\sh /sdcard/arcrecovery/recovery/sh
adb push files\chargerLT15 /sdcard/arcrecovery/bin/charger
adb push files\model /sdcard/arcrecovery/recovery/model
adb push files\chargemon /sdcard/arcrecovery/bin/chargemon
adb shell su -c "cp -rf sdcard/arcrecovery/* /system"
adb shell su -c "chmod 04755 /system/bin/chargemon"
adb shell su -c "chmod 04755 /system/bin/charger"
adb shell su -c "chmod 04755 /system/recovery/sh"
adb shell su -c "chmod 444 /system/recovery/recovery.tar.bz2"

Ups

Sorry i said before long day today!

Here is one with SH included.

Hope it works for you, if not i have to put it into system.img directly or you have to do all that on your own via shell directly!

Regards

Doesn't appear to be at the moment stuck on the Sony Ericsson screen when I choose reboot into recovery but it boots normally when I adb reboot it.

originlabs · Apr 21, 2011

Powered off, then booted with back button held town, just bootloops

Bin4ry · Apr 21, 2011

well this is quite good!
It seems the phone tries to start the recovery but for some reason it won't start!
It's designed the way that on next reboot it have to reboot normal, so no need to worry about this behaviour, it should be stick on the logo aswell if you push the key during boot now!

Let me think about this tomorrow, i have to think if the problem is the compiled file or the script! If it's the file we will have to wait for Z, he has the sources on the recovery and i'm just too lazy to reconstruct them for the ARC

But you can check if all files are in right place with right permissions and IF they are really the files ?

But if you DONT press a button it boots okay or not ?

Yes, booting with no keys is fine.

Does the recovery mount and filesystems, and if so, does it write a log file?

Bin4ry · Apr 21, 2011

Just look in the chargemon and extract the tar.bz2 to see how it works.
I think that the init from recovery (the recovery itself) is not working because of incompatible compilation.
So it cannot write anything into logs!
But it's good that the script itself is still working, we can create a working recovery now from this base

I go and get some sleep now! cu
