[Q] S3 stuck in boot loop - Galaxy S III Q&A, Help & Troubleshooting

Hi there,
I have a samsung galaxy s3 i9300 which I have cyanogen mod 10.1. I woke up one morning and it was stuck in a boot loop.
So I downloaded the latest update and gapps and stuck them on my sd card, booted into clockwork recovery. I wiped the user data, cache and dalvik and installed the latest cm and gapps and it's still boot looping.
Can anyone help? I have no money to buy a new phone...

I think the best option would be back to stock ROM
Or it's just a sudden death syndrome..

Factory reset and flash an official stock rom via odin, if you can still boot into recovery then you might have just a corrupt system partition (it happened to me once and a nandroid restore fixed it).

I'm using heimdall as I use kubuntu on my laptop.
I'm having the hardest time finding an md5 file that has the right files in it to use with heimdall. Technology hates me...

Had the same problem today!
Already told here what happened, going to quote:
I have a Samsung Galaxy S3 Gt I9300 16Gb for about a month and so far always worked without problems, and today, from one moment to another, I listen the phone to restart and when I look at the display was the boot image, just say "Samsung Galaxy S3 Gt I9300" and is flashing at intervals of 3 or 5 seconds without passing that boot image, just taking off the battery that it switches off. I'm desperate because I don't know why he had been so, or how to resolve the situation !
So I entered in ODIN MODE and pressed ''continue''
After that it appears on top left in tiny words the following:
Odin mode
Product name: GT-I9300
Custom Binary Download: Yes (6 counts)
current binary: Samsung official
system status: official
And appears in the middle the android logo and below ''Downloading... Do not turn off target!!''
EDIT: when I left the download mode by long-pressing the power button, before he tried to boot again appeared in the middle of the screen a grey battery with a grey circle inside, what is that mean?

I found a tumblr post with a tutorial for heimdall. It won't let me post links, so I'll have to put in spaces.
h ttp: // wildabdat.tumblr. com / post / 13450595781 / flashing -androidk- rom-on-l inux-wi th-no-odin-stoc
I've not been having much luck with it though, I keep getting : "Setting up interface failed!" and "Failed to initialize protocol!"
May work for you though.

Find a Windows pc and use odin to flash the latest rom for your country at sammobile. After that boot into recovery and factory reset.

that answer was for me or for the user Chibi ?

Chibi. You asked what the battery icon means. It means your phone is off but accepting power via usb
You should try factory reset

I just tried to flash the firmware with Odin and installed one from the links on the Guide Thread.
All the process was ok but when the phone reboots doesn't pass from the boot loop, stays in there and if I try to reset start do blink again.. help please
(can't enter in the recovery to wipe, only in download mode)

your efs can be corrupted

If it is corrupted, you can only save it with a backup otherwise its a service centre repair.
You should try and flash recovery via odin though, see if you can access. Probably not much else you can do.

Tried flash via Odin and after the re-boot it stays with the same boot loop

Repeat its a service centre repair .

ok thanks.. It's in warranty, but, do I have to present the buying receipt ? Because I don't have it
But this is ridiculous, I spend a lot of money on a phone and 20 days later just bricks from nothing
it's exactly this that's happening on my phone:

The flash counter 6 will void your warranty. You can but try

So after some attempts to flash a stock ROM via ODIN, my phone wasn't being recognised by it, so I couldn't get it working even after installing drivers for my phone.
I don't have the $300+ to pay for a service repair centre to fix it, so I'm going to attempt to replace the mainboard myself.
My little S3 is dead to the world at the moment.

boot problem not like the others

i'm posting this thread because of being desperate for an answer , which my s2 i9100 is not booting i tried flashing stock rom , villain rom , cm9 flashed kernal ,bootloader , repartitioned but no luck and can't go into recovery mode only download mode ( odin mode) and in when flashing, every thing goes smoothly and it passes in odin but then it stuck on boot logo but in cm9 and villain rom with the yellow triangle but not with stock so could it be a hardware defect?

no i think he can, as he said he flashes custom but still hungs, unless he meant he flashes cwm.
also remove the cable and try getting cwm, it takes time, on my phone it tooks 3 times the i9100 logo and on third time after displaying logo cwm recovery comes

As long as you can get in downloadmode you`re oke. Look om www.sammobile.com/firmware for the stock rom you need (country or region you live in) and flash it with Odin. See item 3 in my signature for a detailled tutorial how to do that. You might need a jig however, but try getting in downloadmode manualy for now.
Stock firmware follow instructions .

I have a similar problem
My S3 does not work after I root it, please give me a instruction link to recuse it. Thanks.
I tried flashing (Odin v3.04) the official 4.1.1 after trying the official 4.1.2 and now neither of them work. I am constantly stuck at the "SAMSUNG" logo boot stage.
I can enter download mode fine and also recovery mode but I am stumped on what to do to fix the problem.
Does anyone have a fix?

Edit: Found more updated version of stock firmware from sammobile, will try that tomorrow and post results.I hope this works, though the problem may be because I cant wipe the dalvik or data because I cant access recovery, I was previously running cm10.1 nightlies and trying to get back to stock.

GT-i9300 stuck at the startup logo
Hi Guys
My GS3 is stuck at the boot logo. I've read and done all but with no luck,
First problem:
EFS error:
"Fake IMEI (usually 004999010640000)
Not registered to network
Fake Serial Number (usually 0000000)"
Now: stuck on boot logo.
I followed the forum for GT-i9500 thinking this would resolve my efs error. http://forum.xda-developers.com/showthread.php?t=2392632
I did the following:
1. installed PhoeniX.ROM.EFS.Backup.S4
2. Extracted the efs backup tar file & created a folder in the root called efsbackup & copied all extracted files to it.
3. Used Root Explorer to copy all files to the efs main folder. overwriting all.
4. Used the terminal:
su
busybox chown 1001:1001 /efs/nv_data.bin
busybox chmod 06755 /efs/nv_data.bin
5. rebooted.
nothing happened I was still stuck with the efs error
Now I entered safe mode, and nothing i could do, used the hold power button + restart.
now I'm in my second problem, stuck at the boot logo.
I can go to recovery & download mode....
Please help, i really need it hey

I realize it's Saturday, July 26, 2014 - But I had this exact same problem a moment ago; I got out of it by flashing a different recovery with Odin v3.09. I've got soft bricked staring down "Recovery Booting" and that's it. I had download mode available, so went to CWM 6.0.4.5 from TWRP 2.7.1.0. I must admit I thought flashing my HTC Titan I via Goldcard was hard, but this is ridiculous which my SG3 has presented just to get something other than Android Recovery 3e. I got Knox disabled, the device rooted despite being 4.3, but it begs the question what's the point of updating to 4.4.x if going backwards becomes an act of God doing it. Update: Another attempt did not fix the booting problem; however it is a solution to get out of the recovery booting and boot into a normal startup and back to your phone being usable from whatever launcher you use (Nova in my case) It will return to normal startup once you do this if it becomes necessary to do so, which is a bit of a sigh of relief. I'm about at wit's end. One problem gets solved but the moment I ran Towelroot which really worked, new issues keep popping up. Is there a way to look at the bootloader or what OS update created this Knox monstrosity and made our lives much harder than it has to be. I don't mean to sound like I'm asking a stupid question but is there an apk or a procedure within whatever flavor recovery we use that will perform the equivalent of the Task29 we use to perform on the HD2, something that will wipe these devices down to their baby butts and start over; thanks?

[Q] Bricked galaxy s3?

I rooted my galaxys3 GT-I9300 recently and flashed with cm10.1 nightly and then with sotmax v14 ROM and it was working perfectly for three days.. I have administered a hard case for my galaxy s3 which covers it fully. Two days back my galaxy s3 fell from a chair and suddenly it restared. After that it fails to boot beyond the galaxy s3 logo. I felt it could not have possibily encountered any hardware problem because of my case. But lucky me i could access cwm recovery and odin mode and hence flashed it again with cm 10.1 and sotmax v14 with cwm recovery but in vain...it doesnt boot beyond the galaxy s3 logo. Again I flashed with stock gs3 rom(correct version ) via odin and followed all the steps like wipe chache.....factory reset etc etc. But Same results as before it is stuck at the logo. Even the blue led doesnt get lit but when I put it to charge it is getting charged with a red led light...I tried all possible methods as far as I knew them. I have very little knowledge about flashing. Now i do not know what to do. I voided the warranty. In odin mode it shows
CUSTOM BINARY DOWNLOADS: YES (1 COUNTS)
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: CUSTOM
I cannot use the triangle away app so that I could reset the counter as I cannot even get inside the phone. All I can access is recovery mode and odin mode. After I flashed it with a stock rom the cwm recovery got restored with the original recovery. With recovery or odin can I reset the counter and unroot and modify the system status to official so that I can get the galaxy s3 freely serviced by samsung? Or is there any other way to make my phone work? Please help me....I feel iam stuck from all sides and desperate. Have I bricked my phone and made it a 500 $ paper weight?...s3 is so light that it cannot be used even as a paper weight. Help me guys. Thanks a lot in advance.

[Q] Help...not booting!

Hi guys, I hope you can help....my phone has the latest cyanogenmod ROM installed and all has been running well...until today.I had the phone on charge and when I tried to boot it was getting stuck on the 'samsung galaxy s iii GT-I9300' screen..I have rebooted to recovery cleared cache, delvik cache and installed the ROM again, rebooted and still not working, so I repeated the same steps but also done factory reset, still the same. I have tried to connect the phone to pc but it is failing to load MTP usb drivers ....which I think is a unrelated issue.
I'm sure I should be able to get it going via recovery, have been trying all day...is there something I should be doing that I haven't tried already?
Hope somebody can help as I'm pulling my hair out!
Thanks in advance.

flash official firmware from sammobile.com via odin
Is product name blank in download mode, if yes then you have SDS and need a new motherboard. If no then flash stock rom using odin after full wipe and format of system & data, factory reset in recovery after flash and see if it boots.
Sent from my GT-I9300 using Tapatalk
If you can go into recovery mode, it's not SDS, if you have backup just restore it, or go into download mode and flash stock Samsung firmware.
Make sure that you have latest Samsung drivers on your computer installed.Good luck.
Hi guys...
Thanks for the replies, I'm in the process of downloading the latest stock ROM, I didn't realise it was such a big file 800+MB!

Well,as much as I have read about SDS, you can't go into recovery mode,you can go only into download mode and there is blank product name.So maybe to OP it's a different situation, and to OP I would suggest to check if product name on download mode isn't blank.

Unfortunately not
1) Complete eMMC failure. This usually happens over night whilst on charge* - The LED may be lit but the phone will not wake. Subsequent removal of the battery will turn off the LED. You will never get the LED back on. The phone will never turn on again. It needs to go to a service centre and have the motherboard replaced
* Being on Charge is NOT the cause. This is a writing to memory issue and it is more likely to happen when teh device is awake rather than in deep sleep. When the S3 is on charge, it holds a wake lock (so remains awake) throughout the entire charging period, meaning SDS is more likely to occur when on charge This does not mean you should avoid charging your phone. If it's going to happen, it's going to happen
2) Half SDS as it has not-so-affectionately become known. This tends to be more of a boot loop of the Samsung boot splash. the eMMC is partially wiped out. You cannot boot into android or recovery . It fails at the boot screen, but the screen does turn on none-the-less. The only; thing you can do is top boot into Download mode.
Hi guys
Just to clarify, the product name on download mode isn't blank....and yes I tried the reset after loading from odin.

[Q] i9300 Brick phone - Uninstalling Miui to Stock Firmware

Hi,
I have a Samsung i9300 with Miui V5 up to date and I was trying to go back to stock firmware.
To do this, I downloaded a stock firmware (I9300XXUGMK7) and flashed it through ODIN. All the flashing process went without problems but when the device rebooted it was stuck at the Samsung Logo. I waited around 10 min but it was completely stuck. I tried rebooting and then again was stuck. I believe it was a problem with the flashing process so I tried it again with a new stock firmwares but I got always stuck at the logo.
The device enters both download mode and recovery mode (android 3e - stock recovery i believe, although it shows the android laying down with an exclamation point).
I already tried several stock firmware and yesterday I also tried flashing through ODIN with PIT File and Re-partioning but I always got the same issue.
Is it another way to move from miui to stock that I am not aware? Is there any solution for this problem?
Help Please.
Thanks a Lot
Pit and repartion then you may well have destroyed the partitions on the memory .
Who ever told you to use pit files and repartition should buy you a new motherboard .
Are their any error messages in odin ??

Hi JJEgan,
I used the Pit file as last option because I already tried several regular flashes through ODIN. No error messages during the flashing process in ODIN. The flashing process always goes apparently well until it reboots and stucks at Samsung logo.
