[Q]Boot Loop - possibly hardware? - AT&T Samsung Galaxy S II SGH-I777

I think my GS2 maybe be a goner. On my way home from work my battery was low so I connected it to my car charger as I normally do. Once I got to the front of the house I noticed that it was going crazy with notifications from charger connected to connect charger battery low as if I was pulling the cable in and out. I took of the cable and the phone died. I put in a new battery (I have 3 backup) and since then my phone has been in a boot loop. All I get is the Samsung Galaxy SII boot screen. I have tried almost every suggestion in this thread http://forum.xda-developers.com/showthread.php?t=1318263
I can get into download mode through buttons pressing or jig.
After using the UCKH7 One click and trying to get into recovery I get "Deleting cryption meta data" and then it goes back into the boot loop. I can flash CWM 5.0.2.3 through odin. I have gone into CWM recovery and wipe/data/factory reset. I didn't receive any errors, but still continues with the boot loop.
Does anyone have any other suggestions? This would really suck if it's bricked since i don't have any warranty for it.

Try copying over a cwm backup to your phone that you can restore in cwm.
Worth a chance with everything else seeming not to work.

Shut Guys There is a solution for this !!!! Just make sure you flash back to stock on 2.3.4 (I777UCKH7) and flash the kernel on this post:
http://forum.xda-developers.com/showthread.php?t=1367800
it will take a bit to load but this should do it!!

Yup just flash a kernel.

[Q] Won't boot past Vibrant screen; recovery works

I recently installed JAC's kernel, and today I was getting force closes on nearly all of my apps. Even market would FC. So I did a nandroid (the nandroid was with the stock kernel), and now the phone won't boot past the Vibrant Samsung screen. Recovery menu works however. I'm guessing the issue is that I shouldn't have flashed a nandroid that was non-JAC kernel.
I have absolutely no idea what to do in this situation. Can anyone help? I really appreciate it, thanks.
UPDATE:
I flashed the Official T-Mo ODIN images, and got the phone working again. I'm not sure if there was some other way without wiping the phone, but this way worked.
I did a nandroid recovery last night of my stock image and it took about 5 minutes to get past the Vibrant Samsung screen, but it ultimately made it past it.
Hm, I must have been not paitient enough. I didn't count but it felt like I waited 4-5 minutes.
I can NOT get past this screen or into download or recovery mode... All I get is a spinning wheel... tried to downgrade from CM7.... I tried everything Ive read to try to get into download mode...any ideas?

I was finally able to get into download mode..... I spent hours getting my google on reading all the different was to get into download mode...Now my phone would not boot past the "Samsung Vibrant" screen and all the different button combos wouldnt work... Here is what what worked for me..
1 I ungluged the phone from the laptop and removed the battery to make sure the phone was off...
2 I held down BOTH vol+ AND vol-
3 While holding down BOTH vol keys I plugged in the USB and BAMM!!!!!! download mode.....
I hope this helps someone.....
didnt think nandroid backed up the kernel
so doing nandroid to get back to the kernel you were on before wouldnt have done anything

[Q] Odin is flashing several hours...

I've flashed my Galaxy S2 with Odin several times and it has worked fine until yesterday, when I tried to flash again, and everything just froze.
I followed the normal instructions for flashing and the phone just stopped at the "downloading" screen where it says, "Do not turn of target!!".
So it has been, for several hours now. The Odin window on my computer seems to be waiting... but for what? Will it ever time out?
Is it normal that a flash session can take several hours?
Is it safe to interrupt it?

Odin will flash, takes less than 5 minutes.
Is there any data running that you can see? I mean at the bottom left. I would suggest you turn off the phone, battery pull, wait for 5 minutes, and reflash back.
If it semi bricked, use JIG to revive it.
Either way, you can't be letting the phone there for the next few days etc right?
Did you click Start in Odin??
Although i don't have an s2(will be getting one soon) did you try to reset your pc? When i was flasing my sgsl i was stuck in this situation where odin seems to freeze everytime. I restarted my pc and poof, flashed without a problem
Edit: was flashing successful? If so maybe you should follow the instruction from the post below.

This might sound stupid but did you have 'auto-reboot' checked? It happened to me once even though I have flashed hundreds of times. Odin was still open after flashing a kernel and never reset.
Start was clicked - yes.
Re boot was checked - yes.
I reset my computer and restarted my phone and - now it's still frozen, but with an icon on the center showing three icons in a line. First is a phone, second is a exlamation mark and third is a computer. Yiipiiiee. It doesn't boot. I can't get into recovery mode. Download mode does work however, but still the same behaviour. It freezes if I try to flash it.
Now what? Where is that reset-button which resets the phone and clears its brain down to original mode? A simple "brain wash" would be nice.
Is there anyway out of this "freeze of death" ?
Flash CWM kernel, download CM7 rom, copy it on SDCard (mount USB storage in CWM, connect to PC via USB, copy ROM), flash ROM from CWM

Try to go into recovery mode and factory reset and clear cache and try flashing again (make sure you are on download mode)
Sent from my GT-I9003 using XDA Premium App
Hold power button to off it (hold a lil longer for this).
Then Go into recovery mode (power, home button and volume up at same time). Try do wipe all data, cache and even dalvik. Reboot and see if that works.
Alternatively, at the same place, go into restore backup.
The man said: "I can't go into recovery mode"
...
Recovery mode doesn't work - nope. But thanks anyway. It's nice to see that people at least try to help. Big hugs to you all.
If I try to flash CWM, I come into the same freeze again. Mindbending stuff ala Samsung, huh. They clearly don't make idiot-safe products. I'm stuck. My next phone might be a StarTAC...
Has happened to me before. KIES was opened. I closed all KIES files and the flashing fun started again~
Good point, make sure Kies isn't running when using Odin!
Also, now that you've flashed CWM, can't you boot on it?
Kies is not running and whatever I flash - it freezes. The green progress bar in Odin reaches maybe 1 cm, but no blue progress bar is visible on the phone as usually happens when flashing. It just says, "Downloading... Don't turn off target!!"
Am I slowly heading towards the brutal-axe-method?
Sounds like the NAND is damaged to me, but I'm no expert...
"NAND" means? Why does it sound like it's damaged? How can it get repaired?
NAND is the flash chip (internal sdcard). Seems that its damaged because you're unable to fully flash it.
I don't think you can have that repaired (if the NAND is truly damaged, like I said I'm no expert), you'd have to get the phone replaced.
With all respect, let's hope you aren't an expert, but better. But has anyone else interrupted a flash process and went though a "freeze"?
I'm looking for a way to reset the phone to use only what was burnt into ROM from first delivery. I just can't accept that it is so easy to mess up a phone, and I doubt Samsung would be so crazy not to build it with a rescue kinda last savior. Am I totally naive? Is my baby dead? :'(
lol I hope for you that I'm wrong also!

Something similar had happened with me too. The phone was stuck b/w flashing with odin. And the startscreen was showing those 3 icons. It was soft bricked.
But I then finally fixed it by flashing CF and then a ROM

[Q] [SOLVED] Stuck on Vibrant/Samsung Boot Screen

I recently flashed the new ICS Passion v11 and this first flash was giving me problems...so I went back into recovery and wiped data, cache partition, and Dalvik cache. I accidentally messed up and rebooted before reinstalling the .zip file and now my Vibrant is stuck at the first boot screen and will not go into cwm recovery. So is there any hope left for my phone? Please help!
Don't worry. Just flash back to stock using Download mode.

I tried getting into download mode but it still just keeps cycling the same Vibrant boot screen. Maybe I'm doing it wrong but if I'm not mistaken it is Vol Down + Power right?
Few things.
First. Under your avatar is a Verizon picture. Are you using the Vibrant or the Facinate? They are different and Facinate ROMs don't work on Vibrant phones and vice versa.
Second. See below.
Make sure you have ODIN OPEN with admin privileges!
1.) Take off your back cover, remove your sim & mirco sd card.
2.) Remove your battery.
Make sure you have the USB plugged into your PC but NOT your phone!
3.) Hold the volume buttons.
4.) Put the battery in.
5.) Put the USB in.
You don't necessarily need the download mode image to be present. As long as you are getting the COM ID to light up yellow in ODIN, just flash back to stock like normal.

Yes, I am using the Vibrant. I was with T Mobile but I switched to Verizon. I was planning on giving this phone with ICS Passion flashed on it to a friend of mine who is still with T Mobile. Thanks for the post about how to get into download mode. I will try it as soon as I get some time to mess with it today.
I have answers!
Hey. I was having this exact problem and I solved it!
Basically, when it goes into a bootloop, all you have to do it take out the battery, pop it back in, and reflash it again. I had this problem for almost all my flashing even odin'ing back to froyo I had to do twice because it froze.
Here was my process:
I went through the process of going into going to Froyo with Odin (twice sometimes if it froze) then flashing CM7(Twice because of a boot loop) and then flashing ICS PAssion V12 (Twice because of boot loop)
Now it works perfect! Also, no need to wipe data/factory reset/cache partition/dalvik cache after coming out of the bootloop. simply take out the battery, go back into recovery and flash it again. should work!

It's Vol Down + Vol Up + Power. then you can let go as soon as you see the word "Vibrant" in white. should take you into recovery
Thank you to everyone that helped me out, especially to you Woodrube. Your post really helped me get things going. I finally got my phone into download mode and flashed back to the stock Eclair firmware with Odin. I then went back into recovery, flashed CM7, and proceeded to flash ICS Passion v11. It took me a couple of tries with all of this because I figured out that the ICS update file somehow got corrupted (Possibly when I flashed the stock rom?), so I just re-downloaded the file and flashed and it worked fine.

NEED HELP!!!
my Samsung galaxy vibrant SGH-T959 is stuck on the beginning boot screen. i cant get into recovery. i take the battery out and unplug it. i hold volume buttons and plug it in and go to download mode. but my PC will not recognize the phone. it popped up and said "this device was not set up properly." i uninstalled drivers that i installed and tried Samsung Kies. but it just kept saying "connecting." Odin will not work either. i see how people say just take the battery out while its plugged in. but that does not work either. i really need this phone this is my daily driver. it will not boot at all it just stays on vibrant logo. please help!!!!

[Q] samsung galaxy player 3.6 random crash/boot loop!

I have an um-rooted samsung galaxy player 3.6 (running gingerbread 2.3.6) I was browsing an app when suddenly it crashed! the battery was low, so at first I thought to plug it in, but before I did, I noticed that it was rebooting every 4-5 seconds. plugged it in, took out battery, tried putting in recovery (put bat. back in, hold power and both volume buttons) but it vibrates and just goes back into boot loop. it pops up with the samsung logo, stays for 3 or so seconds, screen goes dark, then it does it again.
I have been messing with it. when it starts booting, my computer recognizes it as OMAP3630 which google has told me is the name of the processor. It tries to install drivers but fails due to "umplugged device" when it turns off
Weird! If you have data to recover try using adb logcat to see what's going on. Otherwise reflash with Odin. I have only experienced this problem when using heimdall to flash my us yp-gs1, but it happens right after flashing.
What app were you using when it happened?
Sent from my SGH-I777 using xda app-developers app
a Forum app. It has not been flashed either. it is all stock 2.3.6 gingerbread. if i put the battery in then plug it in (without hitting any power buttons) it goes to a loading circle (that does not move at all) and just stays there. the computer does not recognize it in this state. its only 3 months old, but I have no idea where the recipt is!
weird! im sticking with my answer tho, if you want to fix it then put it in download mode and flash it
if you cant get to download mode then buy a $2 usb jig
Tried it! no luck. got it in download mode. ran odin and It said pass! BUT it only took 3 seconds? and then instead of flashing just samsung then rebooting, it started flashing samsung with a caution symbol under it and rebooting. went to do it again and it says suctom binary current binary:custom. so it seems it worked but did not fix my problem
Did you flash normalboot and factoryfs both?

I had a similar problem with the galaxy player 5.0. Took out my micro sd card from it and somehow that worked. Hasn't gone on any reboot cycle since.
I was gonna try the fs whatever one, but now i cannot get my computer to recognize it! i tried another factory reset and that didnt help. i got it to work once. Guess I will have to keep trying? I got school so I cant do it now (16, junior in High school)
yep you'll need to get to download mode to flash it. like i said before, a $2 usb jig will always do the trick (i loooove mine)
I dont have any problem getting it into download mode, my problem is getting the computer to recognize it. gonna have to try it on a dif computer I guess, which is weird, because I got it to work once, but now it wont. I flashed the normalboot the first time, what did i do wrong? should I have flashed the other (fs or whatever is is) one instead? thanks for the help!
When I'm in a bootloop after heimdall testing I need to flash factoryfs. For you I would say flash both. Try another cable/ try another USB port

[Q]S3 bootloop, no recovery nor download mode

I'm using v40 of temasek unofficial cm11, Boefflea version 11 kernel.
while I was using my phone, the phone suddenly went into a reboot and started the boot-loop, even when I pull the battery out and put it back in it starts booting immediately and goes into the boot-loop , whenever I try to go into download mode or recovery mode, once or twice I will be able to reach it, but 3 seconds in, it restarts and goes into the boot loop again (I can't choose between restarting or going into download mode)
would a USB jig help me getting into the download mode or will it be 3 seconds in and restarts?
would a service center help me retain my data as I need them?
Thank you.
momentarily I've managed to be able to access download mode and the laptop started making a sound trying to identify the device, too bad the battery fell off (or the phone restarted) lol
anyways I still need help because I couldn't get into any of them
If the phone starts the moment a battery is inserted then usually the power button is stuck -try giving it a wiggle, or get it replaced.

yeah will do that once this gets fixed lol ..
for some awkward reason, I found out that once I pull out the battery I can use download mode
what should I download?
I tried flashing CWM but I get back to the bootloop ... should I install a newer bootloader?
No, bootloader is irrelevant to firmware. You would be best to flash a full stock rom with odin then factory reset and see if it will boot. I would suspect the power cycling may have caused partition problems if recovery got wiped.

which would mean I would lose all the data in the previous cm11 right?
I'm trying my best to flash a recovery but I think it got wiped for good.. I'm trying to flash it over and over again .. (I unplug the battery once I'm in download mode to prevent the sudden restart) .. before I flashed the CWM through odin I was able to go into a glimpse of a recovery mode, now I can't seem to see it at all...
is there a way to just copy the data (mostly pictures) through odin or adb with my phone current state?
Google says it might be possible

only through recovery mode or hoping your phone would suddenly connect after many boots lol
I don't think that will be my case .. oh well
as long as I can get my phone working again
going back to stock rom didn't fix the issue. can't access anything yet.
any help?
if anyone is reading this, I've been looking everywhere for a stock rom with pit file, I think that's the problem I'm facing since I have different bootloaders and different modes, somewhere around that I jacked my partitions and I think this would help putting it all back
I've found ones for android 4.1 but nothing of 4.3 .. since I came from 4.3 stock rom and then 4.4 kitkat temasek I think 4.1 won't help me at all
time to go to a service center I guess.
OK this is weird...
after I gave up I put my phone on a recover firmware that for some bizarre reason brought it back to life!!! I just put the phone back and left .. 5 hours later it was on and working.. I was able to access the phone for a brief moment.. but for some reason again I wasn't able to get the touch screen to work... I was able to raise the volume.. restart the phone.. but nothing on touch screen..
then it went back to the dead state...
any ideas?
