[Q] GT-I9100 does no Boot - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
so the main Problem is, my GT-I9100 does not Boot properly, or turns off pretty fast (it somehow does boot, but it turns off while booting).
I'll try to explain step by step what i did so far.
I had a Custom Cyanogenmod 9 Rom on my Phone and it worked for like half a year now (was too lazy to update).
And suddenly it wasn't able to boot anymore as described. I thought it was the Battery so i charged it for a few hours, but still couldn't boot.
After that i tried to start into CW Recovery, wiped Cache, Wiped Dalvik -> still same problem.
Then i just let the phone on on Recovery mode until the Battery was totally empty, recharged to 100% -> still same problem.
So i thought, the rom might got crushed howsoever -> installed Original Kernel with Odin BUT the problem still occured....
That's the point where i am right now.
The Phone starts, the "Samsung Galaxy S2 GT-I9100"-Logo shows, the Boot-Logo shows up (Cyanogenmod logo showd up as well as now the Samsung Logo). On CM the Phone turned off while booting, now it always gets through the Samsung boot Logo, it initialized some apps (cause off Factory Reset) like 9/46 Apps then shuts down, after turning it on again it starts returning to initializing the apps now and again after a few initialized apps like 10/37 it shuts down again.
I kept on turning it on until all apps were initialized and now it tries to instal the initialized apps but shuts down after a short time again. And it is not able to instal a app in that short time, so i wont make any progress anymore with turning it on over and over again...
Don't really know whats wrong, already unplugged SIM. I thought about it being a Hardware Problem... But maybe it's not and you might know some way to fix it
I'll get my HTC One soon, delivery started yesterday, so it's not that much of a problem, but it's a shame 'cause i wanted to give my S2 to my brother

[Q] Problem with Cyanogen 6.1.1 - Please help!

Installed Cyanogen 6.1.1 and GApps yesterday (wiped cache partition, Dalvik cache and battery stats before installing). Was working great all night and most of today. Much faster, not crashing like the JIT was causing my phone to do.
This afternoon the battery seemed to be charging slowly so I restarted the phone. The phone kept getting stuck in the boot screen (with the blue android on a skateboard). I took the battery out and tried again. Same thing happened about 4 times, then finally it went through and started the phone. However, everything started crashing one by one when i got into my phone (force close) and I wasn't able to do anything. I had to pull the battery out again to restart.
It seems to be a toss up now, it either gets stuck in a boot loop or it starts up and everything crashes. I can't even get into XRecovery for some reason so I can't wipe to factory defaults. Seems like the phone is wrote off.
Is there anything I can do? Any help would be appreciated as I am lost without this phone.

[Q] Continuos hangs issue

Hello,
since yesterday my Galaxy S2 (summer 2011) started to act wierdly and I am trying to figure out what is the problem.
I was running the latest Sentinel ROM, and I found it "freezed". So I forced restart long pressing the power button. After the restart, I found it freezed again after some (short) time. It also freeze on the boot process.
Apparently in a random way.
So I tried from recovery a factory reset, full wipe, and reinstalling the ROM. Problem still present.
Today I tried logging with ADB logcat, but I can't figure out the issue from the log. I thought a problem with Mali driver shipped with the ROM, but actually it freezes sometime also on boot (so before loading the drivers)
I tried then to flash back the Samsumg original ROM (JB 4.1.2), which apllied nicely. However it freezes also with Sammie's ROM. Also on boot. By example I one time I got the black screen with the writing "Samsung Galaxy GT-9100" getting grey, with some horizonatl black lines. So frozen.
Flashed again with ODIN, again nicely, but it keeps on freezing on boot.
I am clueless. Could it be some issue with the battery? (it's the original, never replaced)
Any help or suggestion appreciated
Thanks
Update:
I tried to flash it back to GingerBread stock by Samsung with Odin. Applied nicely.
It still keeps on randomly hanging :-|

[Q] Phone/Launcher keeps rebooting

First off all, I'm not sure if this question is answered else where.
I have my S2 almost since the day it came out in NL.
Today a problem occurred. After I boot my phone it keeps rebooting the launcher (not sure if that's the correct name). The phone it self stay's on, I don't go back to the Samsung logo or what else - just Android it self keeps rebooting.
I run Go Launcher Ex for a long time, never had problems with it.
I assume it's a memory problem.
Had a similar problem about a year ago, where my internal memory was stuffed. After removing some apps etc. my phone was just fine again. Problem today is I cant do anything. Connection with pc fails, because of the rebooting software. I'm not even fast enough to get to the Android settings.
Edit: I tried booting in Safe Mode. Which works, till it reboots into normal mode.. and keeps rebooting. And of course there's no time to get something done in safe mode.
- Phone get's really hot when this all happens. An other indication for a stuffed memory(card) I think?
- Removed the SD + SIM, no changes.
Edit:
I was quick enough to change the launcher to something else (i believe Nova, via Home Switcher). Then reboot my phone in Safe Mode with Nova on, then the reboot of the software starts again.. and it forces itself into Go Launcher Ex without Safe Mode.
Thanks in advance,

Go to recovery and wipe cache and wipe dalvik Cache. If still not working then do Factory Reset. If the problem is still there than flash the rom again.

As my main goal was to get my data from the phone I suprised myself a lot and I'm copying as we speak the whole /emmc/ via SDK tools.
It's gonna take a while - I assume it's copying the whole 16GB.
After that I'll try factory reset's etc. and check if I can use my phone again.

[Q] [Help Needed! !] Battery Drain and Logo On Boot Screen displays Android is upgra

I own a stock rom rooted note2 with Os 4.3 JB. Since few days battery is draining fastly, it is discharging when being charged but it doesn't discharge when the phone is switched off. Also, whenever I restart or power on android it starts with logo which says - " Android is upgrading.... Starting apps.... finishing boot...", this happens on every start up although android works after that but drains at very fast rate. This happened after flashing audio zip for increasing volume from this thread " http://forum.xda-developers.com/showthread.php?t=2799537 ".
Please help! ! it has imp. data, and I have to recharge it again and again, avg battery capacity of note2 stands for 8 hrs but it just drains out within 2 ~ 4hrs on light usage. I did wipe out dalvik cache because of problem with super user which is working well right now( this fix I found on XDA). I went to recovery mode to find problem for the same I.e Android upgrading, there on clicking both reboot and shutdown ( once at a time), error poped out saying- " root possibly lost. Fix? ... no... .no... fix root (/system/xbin) etc., then after applying fix, the device rebooted and showed android upgrading ... finishing boot... then I went to root checker it said rooted and all the other root functions are working, but now battery is draining,(discharging even while charging), after switching to recovery mode and again rebooting, same root fix error repeats itself and Android is upgrading ... finishing boot .. logo is displayed. Could you please suggest any other way so that instead of doing factory reset I can revert back these errors without unrooting or factory resetting as I myself had thought of doing the same but it is not possible, even reloading rom cannot happen since I didn't save latest rom which I was supposed to do after eradicating earlier problem but now this error has occurred.
Thanks in advance.

Weird problem, now without system

Few days ago my HOX+ suddenly turned off and would turn back on, but crashed after few seconds. I plugged the phone to a charger and everything worked again. However, since then the story happened over and over on various occasions. I thought it was my fault, because of playing with some root apps; reverted everything back, but problem still existed.
I decided to flash a new ROM. Everything went fine, flashed kernel, wiped all, but after starting the install of the ROM, my phone crashed after the line "patching system image unconditionally". I tried to restore stock backup, but after reaching few percents, phone crashes again. I realized that this might likely be a hardware issue.
Furthermore, I can't enter recovery (unlike bootloader) without charging my phone even though I charged the phone before doing anything.
So, is there anything else I can do or should I put my HOX+ into a recycle bin?
