[XDA Assist] Demoticator:
Hi all,

Since a few days I have a very frustating problem with my Galaxy S2 (i9100) after I installed some new apps. At first all seemed good, but then the low space warning came. I tried to delete some apps, but the main problem is that, with the low space warning coming, all apps (system ones also) started crashing. The result is that even if I can go into the application management menu and delete some apps (it says uninstall successful and the apps disappear from the menu), in fact the apps don't seem to be uninstalled. When I reboot the phone, the apps are still here and the status is the same (low space and apps crashing). I also tried to wipe the dalvik cache through recovery but that didn't change anything. I also tried the *#9900# code to delete the loigs but nothing happened (I suppose the process crash before deleting anything).

I wanted to uninstall some apps through adb but when I choose the USB debugging option and plug the phone, nothing seems to happen, I can't see the device listed through adb devices. My guess here is that, as system apps are crashing, although the usb debugging appears as set, I can't in fact set it.

Next step was to reboot in recovery mode and try to access the phone through adb, but it seems the stock recovery mode (3e) doesn't allow adb connection.

Then next step is to try to install CWM (which supports adb if I'm not wrong). I can boot the phone in download mode, so I should be able to do the installation through Odin but I have some questions concerning CWM version. In most of the tutorials I saw, they're talking of JB and ICS version for GS2, but my phone is still in gingerbread (2.3.3). The CWM site isn't very clear about the versions (only talking of Recovery and Touch Recovery). From reading some blogs on Internet, it would seem that the 4.0.1.5 shoud be working with Gingerbread but nobody seems affirmative about that.

If even deleting apps through adb doesn't solve the stability issue, I hope to be able to do a full backup of the phone through CWM.

My goals here would be (in the following order) :

a) Get my phone fully operational to be able backup everything (sms, app list, data, ...) and continue to use it as-is (on the short term, time to install some kitkat rom)

b) Get an adb connection to backup everything (you can backup nearly anything through adb (sms, ...) ?) or a recovery installed permitting backup

c) Get a way to at least backup the data

So :

1) Have you ever encountered this behaviour ?

2) Were you able to solve it ? If yes how ?

All the threads I have seen (either on XDA or other forums/websites) talk about deleting apps, deleting logs (either through CLI if root or through the *#9900# code), ... But all these people seem to still have the control of their phone, contrary to me.

I have a few other questions :

3) Can you confirm that the stock recovery mode indeed doesn't support adb connections ?

4) Does CWM indeed support adb connections ?

5) What version of CWM would work with my phone ?

6) What are the risks of using another CWM version (if none work with gingerbread) ?

Thanks in advance for any assistance you could provide.
