So I was recently downloading new apps over Playstore, using Whatsapp and quite a few other apps were running in the background. My battery was fairly low, and the phone was beginning to slow down. I believe as I went to charge it, or just before I tried charging it, the phone shut down and then rebooted, but never rebooted past the yellow triangle.
I rooted, and flashed a ROM about 2 months ago, so I am accustomed to seeing the yellow triangle when I switch on my phone, and wasn't fussed about it being there. I flashed a nightly ROM I believe it is called, and it was an S3 type Jellybean ROM. (Forgive me for not knowing the technical names).
I can boot into recovery mode, but whilst looking in recovery mode I have seen messages such as E: Can't mount
I'm using CWM-based Recovery v6.0.2.9
The ROM I was using enabled me to use face recognition to unlock the phone if that helps.
Important thing to bear in mind is the fact that I had been using my phone after a root/ROM flash for about 2 months, and it wasn't immediately after a root as most seem to experience on XDA.
How do I recover my baby again?
Enter Download mode.
Flash stock firmware via Odin.

The phone eventually switched itself back on, and I saw a message saying Android is updating... It is working fine now without any Odin updates etc... Is that normal?

It seems u wiped the Dalvik cache in recovery. That usually results in a longer booting time.
Since ur phone is not stuck anymore, there is no need to flash via Odin.
P.S. Write down the info given in Settings > About Phone. That will help u know which rom u have, which kernel and what android version u are on.

Hi there, I have a friends S2 of which i was meant to repair...the symptoms he described the phone having seemed like a fairly simple repair. On the contrary it is rather difficult. I have searched several forums for a possible solution and found none. At first the problem was getting the phone to start or at least charge the battery, later discovered the port was busted so i used external battery charger. Now the phone boots but doesn't pass the initial Samsung logo screen ( the one that shows the phone model and what not). Tried looking around for solutions but only found answers for when download mode is accessible. I have tried several times to enter recovery and download but have had no luck....
PLEASE HELP :crying:
Relax mate!
What you have is probably a bootloop.. Are you absolutely sure you can't enter Download or Recovery modes?

Ur next option would be to use a USB Jig, but it seems you can't because of your damaged port.
Come to think of it, even download mode can not help if you cannot use ur port.
Am sorry.. but I don't know what else to do other than taking it to a Service Centre. You might as well replace the port also then.

Hi there...sorry i know its been a while but i had revision to do. Coming back to the phone, the port was replaced and we used a jig (purchased from eBay--XD)
went to download mode, used ODIN v3 1.85 and installed stock rom. After successful install, the phone reboots but then gets stuck at the samsung sII splash screen which the switches off and then reboots to the dead battery trying to charge icon.
any reason as to why this may be happening???
Bootloop.
If you are on any ROM but 4.0.4, go to recovery and wipe cache & factory reset.
You keep getting a bootloop? full wipe and/or nuke script.

Can't....recovery doesn't work...only download with the help of jig.
Thought I was the only reply, check under the battery, see what model you own.
Let us know.
I stand correct, I saw the others replies. Still do that I suggested just now.

i have tried both v5 and beta v6 none work....it comes to the splashscreen with the model number but this time it has a yellow triangle on it. I tried getting into recovery mode by taking the battery out, holding the volume up button and home button then put the battery in and power the phone. nothing happens....any inputs.

Try again. Since the kernel has been flashed successfully, u should have CWM now.
Try removing battery, wait a few minutes, reinsert. Then press and hold volume up button first, then home button and then the power button. Remember to hold all three down until you enter CWM recovery.
Good luck!

Ok i just rewrote with tech support in mind. I start my phone and the symbol pops up as normal with the yellow exclamtion mark. Then its followed by a a purple seryia ying yang logo and then it goes black. Im not sure if it is shutting off when it goes black or if its still on, i do know that when it goes black my computer is still trying to search for the phone or something (drivers are beign reconized or installing??). So that is what my phone is doing. !!!!!!! I can enter recoverey and download mode. (so hold volume up and down)
When ever i flash a rom i get a black screen, am i flashing the correct rom/kernal??
btw this was caused by trying to simunlock on a nightly cm10, didnt work so thought to flash back but i ****ed up the flash.
pleas help me i start summer school tomrrow and this is stressing me the **** out.
1st-check ur phone's model since u can't even spell it right
lololol
Hahah yea sorry I've typed an entire semester on my laptop key board and im trying ot make the transistion to the new spacing. I looked under teh battery (threw out the box unfortunatly) and the modle is GT-I9100M
under that it says A3LGT9100
Go to sammobile.com and download a stock firmware for ur device model, ur region and carrier (if any).
Then enter Download mode, and flash the firmware via Odin.
From what I read, it seems u have flashed a siyah kernel (ying yang logo at boot). What files did u flash till now? How did u try to unlock it?

I am now getting a constant loop and i took the battery out. (the logo sits there and dodesnt do anything. ive tried putting th ebattery back in a coupkle of times even after an hour and w.e)
Could this be hardware? i can still download mode now that it has started looping and i can still go into recovery mode. (so up and down)

If u are on CM now, and you can enter Recovery, wipe cache, dalvik cache and fix permissions to see if it boots.

Yea i dont think i am any more i have been trying to flash other roms. when i boot i dont get the cyan circle logo. When I turn my phone on now all it does is show the S2 splash screen WITHOUT the yellow exclamation mark now. When i put the battery in even sometimes it just turns on its own and loops the splash screen (like not "loop" but just shows the splash screen steady.)
I took the battery out so it doesnt burn the logo into the screen haha. Thank you for the help, I just started spring classes.
That means you are in stock rom. Which did u flash last?
If its not 4.0.4, try entering recovery and doing wipe data and wipe cache partition.

I had tried oing that at least 4 times before and fo rsome reason it worked this time, I think it was becasue the battery cimnepltly drained (like to dead) but im really not to sure.
Either way THank you so much for making me try it one more time, or pointing me towards the correct rom or something.

Don't forget to put [Solved] at the begining of the title
About three weeks ago, he suddenly started warming up , then the signal went very bad, and this week the play store and google service something, started to stop responding and closing, the annoying thing was the pop ups about it, and they froze my SGS2 every 5 seconds.
I decided to do a factory reset today but when it rebooted it stucked on the boot logo
I'm still able to enter recovery and download modes, and so i wiped all data and cache through there. The phone boots up, for a few seconds, then reboots it self and stucks at the boot logo
Then I realized the only way is to flash a stock rom through odin, but computer ain't recognizing the device suddenly.
Now Im out of ideas , please help
firmware : 4.1.2 jellybean stock rom
ROOTED
btw: I tried to flash siyah kernal from the CWM when he boots up, but its impossible in the amount of time he gives me until he reboots.
Look for @Hopper8's Odin troubleshooting guide here on XDA.

Hello,
Recently I went from Cyanogenmod 10 back to the newest stock firmware with the Philz kernel on my GT-I9100. Since then I have problems with the phone (seemingly) randomly crashing. It freezes and needs to reboot - either by holding the power-button for a few seconds or it will (try to) reboot after a while on its own.
The issue is that it doesn't manage to reboot after these crashes. It gets stuck on the screen before the Samsung boot animation, where it displays the phone model (and where the yellow triangle would be displayed, if I had a custom rom installed). Nothing happens after that, the screen doesn't change, even if I try to reboot again.
I've tried clearing the cache partition and also the Dalvik cache from recovery mode (which is still accessible) but the phone will still not boot. Interestingly, what does help, is making a backup of the phone using the clockworkmod and restoring it immediately afterwards. The phone will then run normally again - until the next crash at least. I've tried restoring the phone to factory settings but the crashes still occur.
I'm starting to get quite annoyed by these crashes and I can't backup/restore the phone every time these happen, as that does take a bit of time. I've had similar crashes with Cyanogenmod but the phone would always reboot after those without problems, so I could live with it.
Has anyone made similar experiences? Would anyone have a suggestion on how to solve this issue?
Many thanks,
Jocbe
Check the firmware you flashed to see if its broken or corrupted. If yes, redownload it and flash again via Odin. If not, try flashing it again via odin, then do a full wipe, then only root it. Let know if that helps!
And FYI, the startup screen (with the yellow triangle) is known as 'boot logo'.

I'll try that during the next few days, thanks! With 'only root it', do you mean don't flash the Philz kernel on there but instead do something like this: http://forum.xda-developers.com/showthread.php?t=2116549 ? I'll let you know if it helped, once I have flashed it and tested it for a little while!

Sorry for the late reply but it took me a while to actually get around to flashing the phone (and then testing it for a while). I thought I should post the solution which worked for me, for completeness reasons, though.
Rather than trying to re-flash the stock firmware, I decided to go back to Cyanogenmod, as I much prefer it to Samsung's stock firmware. I simply installed the .zip-file in recovery mode and since then things work as they should - so far I've not had any major crashes or problems rebooting. I suppose something might have gone wrong while flashing the stock firmware before.
Btw, if anyone is interested, the problem originally was that the phone would crash entirely, whenever a single app crashed. So essentially, whenever I should have seen something like a 'someapp has stopped unexpectedly'-message, the phone would freeze, turn off and get stuck at the boot logo.
Anyway, this problem is resolved for now
Please add [SOLVED] to the title of your post then.
