Bootloop

Uzi2 · 07-03-2012, 19:59

I think I'm screwed here - any suggestions gratefully received...

I was trying out loads of different apps from the market and I came across the situation that apps wouldn't install. It claimed it was due to lack of space, but there is plenty of internal memory. Thinking this was likely to be a cache problem, I cleared all caches and rebooted - no joy. So I decided to reinstall. All appeared to go well, but the boot anim just loops. There's probably something in my settings that is causing this, so I want to wipe data, but adb does not work from the recovery. I've tried reinstalling from SD card, but I get the same bootloop.

Is there any combination of key presses to enable access to adb or is the limited recovery the only option available?
I just want to be able to do a full reset prior to booting. Every other android device is capable of this.

P.S. Kizune, can you change the thread title of the link I provided to "z2 Firmware Compilation and Recovery Mode".
Should be very helpful to users who have problems with their device and they want to "Hard Reset"

Yes, I'm aware of how to do this (p19 of the manual), but I want an additional option to perform a full reset (erasing all user data). This is the limited recovery to which I refer.

Kizune mentions wiping via the adb, sadly I never tried it as my device has not gotten to the point of no return yet. Kizune could maybe make a guide but asking him might be the right thing to do if you want it posted here.

@da1: He said in the first post he already tried to use adb.

"so I want to wipe data, but adb does not work from the recovery"

@Uzi2: So did you use the Recovery Menu to re-install the current firmware? It helped for me when my Z2 was caught in a bootloop.

Thanks for your input Kizune. I've tried all options from the recovery menu including the beta firmware installed from SD card. I'm sure the problem is caused by what is on the data partition and not what's on the system partition, which will get wiped by the reinstall/update process. Caches should also be wiped in this process. A recovery should have the option to wipe data (factory reset), which I'm sure would solve my problem.
If it was possible to access adb from recovery, I could wipe it from there.
I think the solution will be to edit the script within the update.zip to wipe data as well as system, but I don't have the linux skills or knowledge of the Z2 partition layout in order to do this.

Good afternoon. Similar problem with Cowon Z2. Trying to establish a market for the instructions (there are 3 files: GoogleServicesFramework-2.3.3-signed.apk, MarketUpdater-1.0-signed.apk, Vending-Google_Play_3.4.6_signed.apk), during installation MarketUpdater-1.0-signed.apk Z2 hovered for an hour, I had to reboot. After that hangs on "PLENUE loading". If you restore a recovery issues:
E: Failed to verify package version
Installation aborted

I downloaded the new firmware 4.35 - Very long did OTA backup, but is successful, no errors. After rebooting again a problem. Downloaded native 4.33 which was installed at purchase. Please - the same thing. Ordered in USA, I live in Kazakhstan, no service. Please tell me what to do. Maybe someone knows how to make VIPe Z2 of recovery?
