[Q] Galaxy S2 Stuck on Boot-Up Screen - Galaxy S II Q&A, Help & Troubleshooting

I have an international version of the Samsung GS2 that i am using on At&t. A few weeks ago i noticed that my phone would suddenly turn off while in my pocket or just left alone. Then, one time i tried turning on the phone and saw that the phone got stuck on the boot animation screen with blue markings all around it. I took out the battery and put it back in a few times and was finally able to get the phone to work.
Today, the same thing happened. The phone turned off i tried to restart it and it got stuck on the boot animation screen (Galaxy S logo). It has these blue markings around it and it can't get past it. The phone isn't rooted and i have not tampered with the system files. I've only updated it once, from 2.3.3 to 2.3.4. I tried factory resetting it but nothing changed and its still has the same problem.
I have a suspicion that it might be caused by the fact that i've dropped the phone a few times. What do you guys think could be the problem and what are my choices in getting it fixed? Would flashing a stock rom help fix the problem?

I would suggest flashing the Stock Rom Through Odin as i once has an issue with massive yellow streaks kind of like what you are getting after a flash before.

I went ahead and flashed a few roms from http://forum.xda-developers.com/showthread.php?t=1075278. The flashing worked fine but it still can't get past the bootup screen and the blue marks are still there.
Would calling Samsung and asking for support get me anywhere?

How long did you wait after flashing the rom? The worst way you could have messed up is by choosing the wrong files in Odin. Did u check that again?

I flashed the rom and rebooted and saw that it was still the same. Does it matter which rom i chose? I tried two or three different roms from the thread. I though they were all stock roms...

Has my S3 bricked itself?

Hi there guys, In need of some help here! Had my S3 for 8 months now and its been fine, Never rooted, Always been on stock OS's from day one.. About a week ago I started to get random reboots and freezes, A battery pull would fix the issue for a while but then it would come back again, They became more and more frequent and then I did the latest update, 4.1.2 (I think) It worked fine for a day and then yesterday morning I had like one restart, After a battery pull it worked fine. Put it in in my pocket and carried on doing my work. When I next looked at it it was on the samsung boot screen, I thought it must be another random reboot, But this time it kept looping over and over, Makes the little jingle sound with the samsung logo and then repeats constantly.. I did a wipe data/cache from the recovery mode and that didn't change anything, I then flashed the latest unbranded UK OS via Odin, But that didn't do anything either, The only difference that made was that it gave me a false hope as when i booted it, It say 'Optimising Apps' an then went from 0 to 30 something but sadly, After that it began its looping of the samsung logo again. Anyone heard of a case like this? Where an unrooted phone 'bricks' itself? Could it be hardware?.. Hopefully someone can help.. I hope Samsung UK will fix this under warranty! Fingers crossed they will! Any help would be much much appreciated.. Thanks!
It sounds like a partial SDS hardware fault if you stayed on the previous UK ROM and didn't update to XXELLA until just a week ago, return it to Samsung for a new motherboard.
ELLA contained a fix which prevents SDS, but won't cure it if it's already happened.

Which firmware are you using?
as Boomboomer said, if you never did a firmware upgrade before your last upgrade you are probably encountering issues with SDS. new motherboerd required
Good luck!

Stuck at boot up screen

I have an old S2 running wananm's JB ROM which until recently, could not boot up all of a sudden. It just gets stuck at the Samsung Galaxy SII logo with the yellow triangle on it. I did a factory reset and it worked after that, until a month later where I am having the exact same problem. This time I fulll wiped it and flashed NeatROM Lite 4.4 on it, but now the phone stucks in boot loop at the samsung boot up animation. Pulling out the battery and putting it back results in the previous issue where it gets stuck at the Galaxy SII black screen with yellow triangle. I boot into recovery and did one more factory wipe, but this time it goes back to being stuck with a boot loop.
Any ideas whats wrong? The phone is pretty old, could it be dying? Before all this happened I did not do any modifications to the phone like flashing new mods, scripts, OC, UV..etc
Flash a official stock firmware from sammobile.
After this root and flash Rom again.
PS: Check ur downloads and if u have the correct Rom for ur phone version (i9100/i9100p/etc)

I already flashed the stock ROM via odin. It is now unrooted. Been using it for a week and the issue just happened again. I now realised that it only happens when I attempt to replace the battery. I have two packs, both are official, one that came with the phone and another which I ordered online. After shutting the phone down, remove the old battery, put in the new one, attempt to boot up, it just gets stuck at the Samsung screen. The only solution is to do a full wipe. Could it be some sort of corruption?
Sure it can.
So if it only happens with it, it maybe corrupt in itself or maybe it's not directly for ur phone/android version etc....
So just don't use it, but that for u have a full working phone

Yeah it might not be android related, but it still is strange.. And I don't believe it'stthe battery screwing it up either. I'll try rooting it and see if it manages to boot up. If not I'll go back to an ICS ROM and see how it goes. Because I only notice all this happening ever since flashing JB. I hope it lasts til July so I can trade it in for the S4.

stock phone stuck in a bootloop out of nowhere

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.

Bootloop remains even after Stock flash in ODIN

Hello guys, I have a serious predicament that needs to be solved.
I haven't did anything major to my phone in years so the past couple days have been a nightmare. Ever since I did a wipe of cache partition after trying to get rid of this "unfortunately, contacts stopped working." message, it's sent my phone into a spiraling disaster. (I have been using stock 5.0 rooted rom for at least a year so idk why the sudden issues)
I've literally tried every method imaginable. I even tried flashing with different versions of Odin and still the exact same problems.
I can get my phone into DL mode easily but Recovery mode only works if I have the phone plugged in at this point (Actually, it seems like the only time when my phone wants to work)
Every time I'm done flashing, it'll load all the way up to the T-Mobile screen then restart the loop all over again :/
Really need help seeing as I need to get this situation handled before work today, thanks!
Nevermind, after more research, I decided to order a new battery and the problem is solved.
Bootloop solved with replacement battery

A replacement battery also solved my boot loop issue. Prior to replacement, it would boot to Galaxy S5 screen, and then reboot. Replaced battery and boots. Put the old battery back in, and it boot looped.

GT-N8010 Stuck on Logo Screen

Ok, first up I know there are many posts out there about this issue because I've looked at most of them and tried them so please bear with me.
I have a Samsung Galaxy GT-N8010, about 4 years old. I have never rooted or done anything to the firmware in all that time except OTA updates & the occasional factory reset to clean things up.
Couple of months ago it was on, i had been using it and put it down and when i came back it was on the Samsung logo screen and has been ever since.
Since i could get into the download page even though it was already bricked I figured i'd try rooting to see if i could fix the problem. Now possibly i should have attempted to get into recovery mode first but I attempted to install CWM (as per posts here). It appeared to install fine. But no recovery partition, screen blinks and goes back to the logo.
I've tried flashing stock firmware, TWRP, CWM - all 'appear' to install successfully according to ODIN, but nothing changes, still stuck on the logo screen.
So does this sound like a hardware issue or am i missing something? The Tab A 10.1 with s-pen looks great, would be a perfect replacement, but is not available in NL
Thanks guys (& gals)
Darren
