[Q] Help with bricked phone/bootloop. - Galaxy S III Q&A, Help & Troubleshooting

Whenever I boot my phone I am greeted with a "Encryption Failed" message. I am new to this kind of thing, but from what I can see, the phone is not finding the internal storage. When I try to mount /data it fails, and if I try to load a .zip from sd card it says it can't mount /emmc/.
If I flash a different rom onto the phone it still has the same issues. I've tried everything I can find in these forums and nothing works. I'm about to give up, so any help would be appreciated.

Are you rooted?
Anyway, just flash a stock rom if u are bricked

[Q] I think I've bricked my att GS3 and need help

I've taken on a bit more than qualified I guess as I rooted my att GS3 just fine and flashed a new aokp rom and was up and running but started to have intermitent flickering. It prompted me to reflash rom with CM10 and this is were my problems began. I wiped data/factory reset, cache partition,Dalvik cache, mounts & storage format cache, and accidentally format emmc which I think is my problem. I was able to still reboot to CWM recovery but I can't do much more than that, and now I can't get to CWM recovery mode at all. Have tried to boot and reflash from ex/sdcard no good. PC doesn't recognize phone to do recovery from backup and I didn't do internal backup which I now know was dumb. Is there anything I can do to get back up and running or did I screw myself and have to get a new phone? PLEASE HELP HELP HELP!!!!!!!!!
Post on attention gs3 forums more help

[Q] Softbricked my i9300

Hi All,
i think i just softbricked my S3. i was running Omega rom 33.2 and found the phone was unstable. Hence i wiped data, factory reset, clear dalvik cache and etc. after flashing the rom, it got stucked at samsung boot screen.
i even tried to reflash the rom but still failed to boot up. after that i decided to flash stock rom using Odin (I9300ZSDLK2). it managed to boot in but then it got stucked at recovery (failed to mount /system (Invalid argument). i thought it could be something wrong with the /system, i then flash CWM to format /system. obvious i wont be asking for help if that step succeeded. i basically got pawned because i am not able to mount /system. anybody can help me?
Have you tried flashing your nandroid backup that you'll have made at one time before flashing a ROM?

no backup. i think nandroid restore wont help also because of /system is dead. i need to solve /system mounting issue.
Try full format then flash a stock firmware package in Odin.
Go into mounts and storage and format: System, data, cache and internal SD if you have it backed up.
Then re flash stock firmware, this has got me out of soft bricks lots of times.

Unfortunately it still won't work. I have decided to send back to sc but before that I need to find a way to completely kill my phone. Meaning no download or recovery mode. Anyway thanks for your help.

If you are able to get into download mode, you can try flashing a PIT file. It will either really brick your phone or fix it. Search for the PIT file in the forums.
Remember when u flash a rom with pit file u need to tick repatition in odin..
But only do THIS in your case,never do it otherwise..
Good luck

Soft bricked.. I guess :s

I had ICS.. backed with titanium and upgraded to JB with Liquidsmooth's rom... however I failed to read that titanium backedup contacts couldn't restore from ICS to JB... after reinstalling Liquidsmooth I thought the error might be with the ROM so I installed Omega's JB rom... nice bootscreen... pity it stayed in a bootloop... I then reinstalled it from cwm after removing the battery (a few times) and getting into recovery.... however it remained the same...
so.. I get into odin.. PDA -> ChainFire's "CF-SGS3-CWM-v5.5-v1.5.tar" worried that all I've don'e is put a ics kernal into a JB rom... I boot into recovery and install an old (possibly original root) ROM... now it boots past the animated logo just stays on the static -Samsung- logo... I can boot into odin.. not tried to boot into recovery...
but I don't have a recovery rom... (I have searched)...
could someone point me in the right direction please
Thanks
Have you tried wiping cache and dalvik, maybe try factory reset.
If all that fails this is what I do:
Boot into recovery
Go to mounts and storage
Format cache, System, data and internal sd card. (of course you will lose all data)
Then flash a full stock firmware package through Odin.
Done

I found a stock 4.04 (ICS) rom... still soft bricked... I'll wipe everything except internal SD card... see if that works.. else guess I got no other option :s... I am pretty much backed up so I'm not completely fussed.. but I know there will be something that was missed...
didn't have to do a full wipe... but when I power-off it still reboots... I have to remove battery to power off?
Just do a wipe from Recovery, often the problem then not.

[Q] soft brick - bootloop

hi there i have had my device rooted for awhile now and all of the sudden it just started to get stuck in a bootloop, just displaying the "samsung galaxy s III GT-I9300T" screen then goes black and repeats
i have a sgs3 GT-I9300T (from telstra, australia if it matters)
i rooted with "CF-Auto-Root" which worked fine and was working fine for atleast a month
i dont have a backup (yes im a noob/idiot for not creating a backup but didnt think there was any reason to)
i have tried flashing the latest firmware from sammobile using odin (with only auto reboot and F. reset time checked)
i can still access recovery (factory or custom from flashing in odin)
i've already tried a few suggestions from some posts on here but alot of them arent for the international/I9300T version so wasnt game enough to try them out in fear of fully bricking it
if anyone can help out with what i should try that would be great
i would even settle for resetting flash counter and system status back to 0/offical so that i can try and return it
current state is:
Custom binary download: Yes (3 counts)
Current binary: Samsung Official
System status: Custom
Did you try factory reset from recovery before/after reflashing stock?

yes and even installed CWM recovery to clear the "dalvik cache"
Here is thought
Pull out sdcard, better format in FAT32, copy few ROM into it by using card reader or other usable phone which has sdcard slot.
Flash any of newest recovery such as TWRP personally suggested, Backup current ROM in case of further needed and then
Factory reset, format /system partition, wipe cache / Dalvik cache, and then flash new ROM too see if it works.
Remember format system partition!

download this file http://checkrom.com/threads/resurrection-odin-checkrom-evohd™-v4.896/
get into odin and flash this file into your phone through the download mode ... if everything works it should boot into cwm recovery .. then wipe data\factory reset , wipe cache , wipe dalvik cache and reboot ... wait 15 mins and it should work!! Good Luck!
woot this worked!
i tried re downloading the file first like qtwrk suggested and reflashing it in odin which still returned the same result but i then downloaded this one and did it and it worked
i got into the os downloaded triangle away and reset the counter then flashed the telstra one again so that it was right back to factory default firmware which is what i wanted, will proberly root it again but will def make sure i get a full backup right away incase of any issues later on.
thank you all for your help
hye me again just thought id write an update on my situation
it appears that the phone had stuffed up again this time tho couldnt get into recovery mode but could still get into download mode
i didnt bother doing the same thing again instead i just took it back to telstra and they replaced it, and they replaced it with the 305 model so worked out alright in the end

[q] help- can't get out of twrp

While performing a ROM change, I ran into this problem: Using TWRP 2.4.1 i got into recovery and did a clean install as usual. Wipe internal storage, factory reset, system, dalvik, and cache, and format data. Done this plenty of times , with never a problem. Today however, when i went to install from external storage, my phone is not seeing the sd card. I can still boot into TWRP, so I tried formating card, then tried 4 different sd cards, but no luck with phone mounting sd card. How do I get an operating system back on this? ODIN? Please advise. Thank you
Boot into Odin flash a stock ROM
okay, Thanks for the quick reply. I've never flashed a stock rom from odin before. Will that unroot my phone?(not that I mind, just wondering). And also, how do I get into ODIN to flash?
My bad I meant boot into Download Mode (if you can) then flash a stock ROM through Odin. Yes it will unroot you, but yo can easily root your device again. Follow the steps Here to unroot.
