[Q] new bootloop problem - Galaxy S III Q&A, Help & Troubleshooting

i just woke up to find my galaxy s3 dead.
i tried to power it on, to have the "galaxy s3 i9300" logo starts to blink in a continuous way and no matter what i do the blinking continues in an infinite loop, till i remove the battery and power it on again and same loop of logo blinking again
i did access recovery, change recovery--> same loop
i did install original firmware through download mode that i can also access (via Oddin) --> same loop
i tried to install original firmware by different components methods (via Oddin) but IT FAILED.
i tried philz touch 4 recovery and it works like a charm with back up and restore -> same loop
so, what is the problem and how can i turn around it.

factory reset

boot to recovery

reboot to download mode
flash stock rom.
i might be wrong, but worth a try.

[Q] Sudden crash and then bootloop, how to fix ?

I just flashed I9300XXEMA2_I9300NEEEMA1_NEE and cf-auto-root. While i was setting up my phone, freezing some apps in Titanium backup, it crashed to a black screen with the notification bar visible. I had to pull the battery and now when i reboot i get stuck at the last Samsung logo in the boot process.
I can enter download mode, but not recovery. I`ve tried reflashing the above firmware twice( with Odin, no errors), but still stuck on Samsung logo.
Any way to revive my phone ?
Thanks
after reflashing, if it succeeded, go to recovery and do a factory reset
Cheers
I couldent enter recovery after flashing just the firmware, i just tried flashing cf-auto-root again wich did the trick.
I did a factory reset and its now booting again
Thanks again
wipe cache and dalvik and factory reset

[Q] Bricked P7510 won't boot after stock reinstall

Hello,
My galaxy tab 10.1 P7510 is dead.
I used ODIN to put stock 4.0.4 (P7510UELPL) on it.
Everything goes well and I get green PASS! icon.
Now my system reboots to the Battery logo. but stays stuck here.
I can hold power button/volume-down to go back to download mode or recovery mode. I did factory reset and wiped cache.
Still it goes to battery logo after reboot.
Is my battery dead or my whole tablet?
Thanks for any help

Reflash via odin, as long as you can get in recovery/download you're safe

I tried that several times with 4.0.4 USA. But no luck.
I am now downloading another region to see if it was the file that was the problem. Although it flashed ok.

OK. I tried several pc's win7 32 and 64-bit. No luck
several versions of ODIN. Noluck
I can boot in download mode. I restored several different versions of p7510 firmware.
Odin says everything is ok. "pass"
But once I reboot I get the samsung logo and immediately afterwards the 2inch battery logo in the middle of the screen and nothing else.
I can press the power button and go back to recovery/download mode but same error.
If I reboot and go to recovery and wipe data and reset it boot up to the logo with padlock icon on the bottom and nothing else.
Anyone seen this problem?
Same but no recovery
I have the same problem (stuck at boot screen). I can get to Odin mode but can't boot into recovery. When I choose it from the download menu instead of Odin mode, the tab just goes blank. I even used Odin to flash anew Recovery (CWM). No luck. Any ideas?

[Q] i9300 keep rebooting and never turn on

Hi everyone.
I have a i9300 and it is stuck in rebooting.
Power key is ok.
I can get it to download mode or recovery mode.
I can wipe cache and partition but nothing change, it keeps rebooting.
I cant use odin because odin didn't see the phone,
I think USB debugging wasn't on. But I cant find a way to open it without turning on.
I am looking for possibilities and solution for 2 days and I cant find any. Please help me.
bootloop
It seems you are stuck in a boot loop. Try clearing the cache & perform a full factory wipe. Then reboot your device.
Hope that helps.

I both try 4.1.2 (with odin) and 4.3 (with octopus) but it keeps rebooting.
I also use octopus box to flash and repair efs.

If you've cleared the partition structure then you've turned a possible soft brick into a hard brick, you'll need a new motherboard now.
Try flashing the rescue firmware, from the thread in general, but I wouldn't hold out any hope.

same problem but worse please help
HI guys i have exactly the same problem but my bootloop was caused by installing recovery through the cwm app and then rebooting to recovery through the app. i rebooted to recovery with an app before and it caused this aswell ...however back then my volume down button was working. i fixed it last time by going into download mode and flashing philz recovery however i cant enter download mode or recovery or boot into system.
PS: my phone doesnt boot into recovery it comes up with the samsung galaxy s3 gt 19300 logo then it comes up with the cwm recovery icon in the middle of my screen and 'clockwordmod recovery v6.0.6.4' at the bottom of the screen then restarts itself.
i dont know what to try i have looked around, didnt want to create a new thread just wanted to find out if anyone has any idea of what i can do except for buying a new volume down button thats my last resort apprently its £35 to fix
easy way to fill up you thanks meter guys as any sort of input and advice is extremely appreciated.
alphadavid99 you fried your lcd when you flashed cwm made for note in the other thread.
Hi i have the issue... I am able to get in Recovery and Download Mode.
While in recovery i had formatted the whole internal memory and tried flashing about three AOSP ROMs (Formatting each time before Flashing) but the only result was the endless boot up screen (not boot loop).
Then i tried flashing a sammy ROM and it worked...
Could someone tell me why am I able to flash Sammy ROM but not AOSP (such as ARCHIDROID & SLIMBEAN).
My Model is GT-i9300
Current Modem - XXUGMK6
Current ROM - S4 Revolution ROM (TM)
Thanks in advance for your time if someone has any suggestions

[Q] I-9300 bootloop and no recovery

Hello,
I have a S3 which is stuck in a bootloop at the samsung logo.
when i turn it on it shows the logo for some seconds then the screen goes black and the logo re-appears.
i can not boot into recovery mode, but download mode is working without a problem every time.
i tried flashing stock firmwares with odin and also tried kies emergency firmware recovery. the flashing always went without any problem, but it had effect. whatever i try, i am never able to boot into recovery and still stuck in the bootloop.
in some tries after flashing the screen just shows the samsung logo forever, but after rebooting it once it then is stuck in a bootloop again (shows the logo - screen goes black - shows the logo...)
i also tried flashing TWRP and CWM via odin, but again i can never boot into recovery mode.
what should i try next?
thx alot for any helpful comment

You can Try this:
1.) Pull out battery
2.) Put it in again
3.) Press Vol up + home + power
4.) When the Samsung Logo appears let it off
I think you press the Buttons too long.
I had the same problem!

i really tried everything, it's not working. btw with i am stuck at the very first image, where it says "samsung Galaxy sII GT-I9300".
i dont think it's just the way i press the buttons because i can reach it on my s1 and s2 without a problem, it's just not working on this device.
could some setting like "nand erase all" in odin help? in other threads there is sometimes mentioned that the internal file system might be screwed up and in those cases a simple odin reflash does not help anymore...
Nand erase will usually hard brick it. Try the rescue firmware from general forum, sticky thread. Follow the guide exactly as it includes a pit file.

thx, but i already did that (multiple times) and flashing via odin always succeeds. then the phone reboots and is stuck at the first samsung galaxy s.. screen. twice i managed somehow to get into recovery (after flashing cwm6) but it then randomly rebooted.
and i dont think that the power button is stuck because when i am in download mode it is perfectly fine it never reboots itself unexpectedly.
Had a similar issue on my tab2 p3100. It all happened when I tried flashing a custom recovery from rom manager.
A bad flash of anything related to recovery or bootloader could be a probable cause.
I remember a knowledge share on one of the threads describing this issue and as mentioned on it all I had to do is this:
1) switch off the device and plug in the charger. This would light up the display showing you the charging status. The status has to show if at least your bootloader part of the phone is fine.
2) plug out the charger and immediately press the three buttons (home + vol up + power) get into recovery mode. This step has to work and help you get to recovery mode.
***Note : the interval within which this step has to be performed is too short since the display would turn off immediately as soon as you plug out the charger. A bit tricky too so you have to be fast. If this misses getting you into recovery, pull out the battery and put it back again. Repeat step1 and 2 again.
3) upon successfully getting into recovery, perform wipe data, cache and select reboot phone from option available on recovery again.
Allow the device to boot. This could take a while since you have performed a data wipe and may prompt for first time set up.
I was able to restore functionality on my tab after these steps and like ppl learn from their mistakes, I then learnt that recoveries and bootloaders are things that needs to be done with a pc only.
Worth a try if you have tried other alternatives and found no go. may help. Who knows..
all the best.
thats also not working. i tried to get into recovery since two days now...
i also tried the steps from this thread: http://forum.xda-developers.com/galaxy-s3/help/solved-pit-bricked-dead-problem-gt-t2535367
but again, after i flash the cf-root (successfully) the phone does neither boot into recovery by itself nor can i do it by hand...
its crazy... in download mode i can see the model number (GT-I9300) and i thought as long as the model number is there and i can enter download mode there should be a way to recover the device.
but i cannot think of anything to try that i have not done yet
If the rescue firmware didn't help then it looks like the emmc chip is damaged.

is there a way to make certain of this? how can i tell if it is really a hardware damage and not just a software brick?
i just dont want to let the phone go, it looks still so shiny
is there anything else that could cause the phone not booting into recovery mode after flashing custom recoveries?

Same here, still didn't found how to fix it.. I guess our motherboard just died..
Howewer I have a solution that "almost" worked for me.
Get a stock firmware in odin and turn on Nand erase and T-flash
When it's done phone reboots and you'll see just "Downloading..." mode when you turn it on.
Then got to Kies and Select firmware recovery...
Enter s/n and model name and wait for the flash to complete.
With it , I got past boot logo and actually booted into android but the phone crashed because I guess I have a memory issue..
Well , gl. If you don't find anything else helpful , try going with this method..

if you succeed to boot the phone, root it and low the values of the CPU, around 1100-700mhz. Thats the only way to stop the random reboots.

Hold up volume, home button and power button, then release power button at sammsung screen for download mode. To reboot your phone hold volume down and power key for 10 seconds.

I was in the same situation, stuck on the logo and blinking light. Flash the latest firmware
It should boot then immediately root, download kernel adiutor and low the values.
