Hi all.
I have installed the Cyanogenmod 12.1 UNOFFICIAL on my Galaxy S II for several months, but yesterday, suddenly, the phone shutted down and kept doing this everytime I tried to turn it on, until I couldn't even go further than the "Samsung Galaxy S II" sign.
At first I could boot in recovery mode, so I tried to do a full wipe and then re-install the Cyanogenmod, but something went wrong during the installation and a dead android with a red triangle appeared in the background. I rebooted the phone, and from that moment on I couldn't even boot in recovery mode anymore.
So I followed this guide found in the forum to fix the issue (http://forum.xda-developers.com/galaxy-s2/general/guide-fix-unflashable-soft-bricked-gsii-t1449771) and it worked well, because the phone installed everything successfully.
Now, the bad news is that the phone keeps shutting down soon after the operative system starts (I can't even finish the initial configuration). The good news is that at least I can boot in recovery mode (in this way the phone is turned on as long as there is enough battery energy, so it is not an hardware problem, I guess).
I really don't know what else could I do.
Can you help me in any way please? Is it a known issue? How can I fix this?
If you need further informations I'll be happy to let you know them.
Very thanks in advance.
You are using an unofficial build of CM, install an official build of CM12

Is your device boots and works well on stock?

My device couldn't even boot in the end. However I solved the problem by changing battery, so it wasn't a software problem. Thank you anyway!

i bought a phone off ebay in december. the phone was working well and then i decided to start installing different Roms on my phone. the phone was not s-off when i was installing these roms. about two weeks ago my phone just started to restart. it does not stay on for more than a minute before it restarts and i have no idea why it is happening. i would really appreciate any help in this matter because it is really frustrating. i think it is a software problem because the phone does not restart when it is in recovery mode or if it is in bootloader mode. if there is anything...anything at all you can do to help me it would be greatly appreciated.

It would nice if you put a title to your thread instead of just [Q].
Anyway, if you suspect its a software problem, why not just flash back to stock and see if it persists? If the problem is still there, then it's most likely a hardware issue. I would replace the battery first.
Sorry about that .. it was the first time i posted something and wasn't really sure what to do. and i replaced the battery and the problem is still there .. i flashed and it still restarted. the weird thing is that if i'm doing something it doesn't restart. like if i'm using the phone as a hotspot it doesn't restart. but as soon as i stop it restarts. or if i'm using the camera it doesn't restart.
Did you wipe/format everything before flashing/flashing back to stock? Are you on CWM or EXT4? Some more details would be helpful.
yes i did that. i used superwipe. i am also 4EX and i S-off the device also. i tried installing the stock rom but it didnt work. it is confusing because once i am in recovery the phone stays on. but as soon as i turn it on it just keeps restarting. the phone boots up and then restarts.
Hi, got a galaxy s2 i19210 and using cm-10-20120926-UNOFFICIAL-i9210t
Was having a few random restarts and found that if I tweaked the voltages it would put an end to this. I found I had to use DreamKernel-GTI9210T-v1.7.1CM10-20121010073231-CWM to do this, so I downloaded it and tried to install via the rom manager.
Phone restarted to install, now when it turns on it says the usual 'galaxy s2 i9210' etc, then it usually goes to the blue cyanogen symbol spinning. Unfortunately, it no longer reaches this and the screen stays black. The lights turn on, but screen stays off.
Can't seem to get into download or reset mode with the key combination and sometimes instead of turning off the phone restarts which makes trying the key combinations a bit harder.
Have tried removing and replacing the battery but that didn't help either.
HOWEVER!
My computer recognises the phone although I can't access the hdd because the phone is locked
Odin recognises the phone
So, what options do I have to get my phone working again?
I've looked at a few threads and googled a bit but haven't found anything substantial
To clarify it's a Galaxy S2 i9210T 4G Australian Telstra phone
So I finally got into odin mode and cleared the dalvik cache and did a factory reset. Installed latest i9210 firmware via download mode and odin and everything is working again. Unfortunately I lost all my data but i'd prefer that than a brick. Still doesn't explain what happened in the first place though, did I use the wrong kernel or go about the install the wrong way? I'd like to go back to cm10 but fix the random resets.
You're more likely to get an answer here. Almost everyone here has an I9100/I9100T.

Thanks bud!
hello everyone, my stock s6 edge on rogers is stuck in a boot loop all of a sudden, fully stock and unmodded, running 5.0.2. i was just walking and listening to music through bluetooth headphones and all of a sudden it stopped, and i looked at my phone and it was rebooting. so i just waited and its still stuck in a boot loop after an hour. it gets to the lock screen sometimes, and then after like a second or 2 just reboots again. i have not tinkered or have done anything to my phone either, and had no issues with random reboots ever, so i have no idea what could have happened
some extra info, when it reboots it doesnt always go to the galaxy s6 edge screen, it sometimes just shows the samsung logo with the animation. i have also tried to wipe cache and that didnt work either. after a few reboots however the stock theme was applied at some point. also i tried booting into safe mode and that also didnt work.
i really dont want to wipe my phone, but i will if it is absolutely necessary. so if anyone has any other suggestions that i can try out it will be very much appreciated!
thanks!

I have had said problem before under the same circumstances (although it was with a different phone)
Try using Odin to install the stock Firmware.
A thread explaining how is right here.
http://forum.xda-developers.com/galaxy-s6-edge/general/sm-g925f-s6-firmware-thread-t3078841
If you don't want the firmware listed in that thread, download from Sammobile.
While some users say it does not wipe the phone, it wipes every time I use it
If this does not work, you should get a warranty replacement.

Thank you for the reply!
weird thing is it fixed itself .. few hours after it started it just booted back up and didnt reboot again, and has been running fine for the past couple hours. but if this happens again i will know what to try next time
Greetings Everyone,
Yesterday i installed the last CM13 nightly via the CM updater in this phone.
But after the phone restarted, a green android and a "installing system update" appeared for a few seconds then after it went black, the screen blinks each 5 seconds or so, but nothing ever happens. I left the phone on overnight to see if something came up, but to no avail.
Furthermore, now i cannot enter recovery mode, only download mode and my computer does not recognize the phone. I tried pretty much everything, the basic guide on rooting i9100, KIES, Odin, Heimdall flashing, offering corpses to the Old Ones and nothing works.
Does anyone have any insight on what might be happening? I installed CM13 on my two phones (a z3c and a Note 4) and everything went smoothly. Now with this i9100 i was using 6.0.1 but everything went to hell after i tried this update.
Thanks in advance
I'm in a same boat

You might find your answer here I'm not clever enough to post the link so you get it "Longhand".
Go To Forum Galaxy SII General.
Scroll to [Guide} Fix an unflashable or soft bricked GSII (i9100G/P/T/ versions included)
Have a good read through it and if you dare go for it . It's a "back to the future" sort of thing, takes you back to "jellybean" and android 4.1.2. (The route I took anyway)! Good Luck!
same problem here! please help me get my phone back :crying:
argethalm, fazallfrd, ThiagovGuerra
I had same problem - but ....... it was software bricked. Like yours.
If I repair then all of you can repair like me.

Everything i take from this link.
You can rebuild with patient.
Recently, I flashed a TWRP and rooted my Tablet (Galaxy Tab A SM-T350). Yesterday, I made the mistake of installing crdroid (https://forum.xda-developers.com/galaxy-tab-a/development/rom-galaxy-tab-8-0-t3912517) and wiping the recommended partitions (In that post). After confirming that the custom ROM worked, I went back into TWRP to install the Google Apps and SuperSU. That's when I screwed up.
After installing those .zips I went back into crdroid, and the "Weather Pro" or something like that, which appeared to be the launcher, kept crashing.
Regretting my choices and wanting to go back to stock, I flashed this ROM with ODIN: https://androidfilehost.com/?w=files&flid=154234
That didn't seem to work, as when it booted into the setup, it would crash and reboot. I thought I had flashed the wrong version of Android on it, and downloaded this ROM: https://www.sammobile.com/firmwares/galaxy-tab-a/SM-T350/XAC/download/T350XXU1CQJ5/194035/
That also didn't seem to work, as the device would do the same thing. Boot to setup and crash. I tried to boot into ASR and wipe it from there, which is what landed me where I am now:
The device booted, went into setup and immediately shut down. The device does not boot at all, and when plugged in, simply shows the circle with the bolt inside, never showing the green circle and the battery percentage.
Quick FYI: I backed up everything with ADB to my PC way before this happened. Don't know if that will help.
What I mean: https://1drv.ms/v/s!AnXXk5PX0LXn3gd4nJiaPXYOKhFv
Anyone know where to begin in terms of resurrecting my tablet?
Thanks in advance
UPDATE: I don't know what happened, but the device is not charging. Still refuses to boot without crashing but I feel like this could help
Update 2: Ok so it turns out I was stupid and the battery was just dead (I thought it was charged after a night-long charging, but I guess not)
