Bootloop after stock rom flashing - Galaxy S III Q&A, Help & Troubleshooting

I've just flashed the stock XXEMD2 via Odin 3.04, i got bootloop so i wiped cache and data from recovery and restarted, but i still got bootloop. Any advice? Every guides I've seen doesn't mention this situation

try these...
1.wipe data and cache from cwm and reflash rom
2. try wiping data cache and system from cwm and reflash
3. make sure that you enter the files in correct field in odin and flash is successful.
4. use a different stock rom package.
5. use a different odin version
hope this helps

I've got stock recovery and a zip backup of my efs folder, when i boot in recovery it says it can't mount the efs partitions. I tried to repartition a lot of times, but still no success.

[Q] Help with bootlooping Galaxy Player 4.0

Followed instructions to flash KlassicRom and am now bootlooping.
Installed Steve's Kernel and booted into CWM where I made a backup.
Then back to odin to install KlassicRom R5 - no errors but on reboot just bootlooped.
After waiting 15 minutes with bootlooping, I booted into CWM to restore. Restore indicated success but on reboot, now just get Samsung boot screen with Steve's android guy in the corner. Stuck on boot.
I can still reboot into CWM and Odin recognizes the player when in download mode, so I'm hoping it's recoverable.
Anyone available to guide?
Thanks in advance for any help!

Boot into CWM and
wipe cache
Factory Reset
go to advance and Wipe Dalvick Cache
then exit CWM and reboot.
Tried the wipes before. Did so again.
No errors reported with Wipe Cache
No errors reported with Factory Reset
Wipe Dalvik Cache reports:
Dalvik Cache wiped.
E:unknown volume for path [/sd-ext]
Reboot hangs at Steve's Android guy and Samsung again.
R5 don't work with steve's kernel. It only works with klin kernel or terrasilent.

Downloaded and Odin Flashed R3
Odin reported PASS
on reboot, bootlooping again.
Booted into CWM and Wiped Cache, Factory Reset, and Wiped Dalvik, then reboot.
Bootlooping still.
Same error messages as before when boot hung:
No errors reported with Wipe Cache
No errors reported with Factory Reset
Wipe Dalvik Cache reports:
Dalvik Cache wiped.
E:unknown volume for path [/sd-ext]
Then bootlooping.
US or international, if US there is a stock but rooted ROM on here somewhere (not the full restore using heimdall), i'll look for it later that you can use to flash back with odin then boot into STOCK recovery and wipe data and factory reset that is what got me out of the bootloops when I first started flashing.
here is the link if your running the US model http://forum.xda-developers.com/showthread.php?t=1512331&highlight=stock+rooted+4+0
Downloaded the stock rom. Odin flashed. Booted into stock recovery and did factory reset/wipe.
Rebooted to joy. Thanks!
Might wait a bit before trying to flash the custom rom again.

Flash the terrasilent kernel and use that version of CWM to make a backup, its a much newer version and backs up things the older misses, also don't have the USB cable connected to the player when your in CWM thats what seamed to throw me into the bootloop, As long as you stick to Klins ROMs only (not using any of those CM7's or anything based off CM7) what you just experienced and solved with the "stock" ROM flash is the worst case scenario when flashing only variations of Klin's ROM with Odin.

[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.

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

[Q] Problem installing custom rom

Hi Guys
Im having some problems trying to install a custom rom into my new Galaxy SIII I9300.
The rom in question is OmegaRom V35
After roooting and all, yesterday i tryed installing the rom with mobile odin, following all the instructions.
The result was the phone rebooted after the instalation seemed to be ok, but got stuck on the booting animation, and never got out of there.
I Had then to inject cwm with odin desktop, wiped data, cache anda dalvik, and then proceed to install the stock rom with desktop odin. All went well and the phone worked great.
I thought that maybe the problem was with mobile odin pro. So today, i went and proceeded to install Omega V35 via CWM. I again put the file on internal sd card, wiped data, cache and dalvik, and the rom started flashing. It all started good but, with no warning, at the mniddle of the installation, when applications were being installed, the phone went automatically and wuickly back to CWM!
Of course the installation wasnt finished, so i was stuck with cwm on reboot. Again made wipe data, cache and Dalvik, tried again to flash Omega V35, and again, the same problem...
In the end, i had to flash the stock rom again.
I searched the forum, but i cant seem to find the problem for this. I followed all the instructions, and had no error messages besides CWM skiping the format of the card, and some message (that i've seen in videos as normal), when wiping Dalvik!
Any clue to what's happening?
A clue read the instructions for the rom .
<b>Installation:Install CWM Recovery with Odin - Get CWM Recovery here
Boot to CWM Recovery using volume up, power button and home key
Backup your device and make sure to keep a copy of the backup to your pc!
Wipe data / factory reset (Not needed if you already have Omega)
Install Omega
(Wipe cache will be done automatically during installation so you can skip this step
Wipe dalvik cache will be done automatically during installation so you can skip this step)​</b>

Maybe i didn't expressed myself correctly, but today i followed those instructions twice, and, at each of these tries the
same thing happened. When the flashing was running apparently problemless it simply stoped and went to CWM without rebooting.

[Q] Can't flash any ROM via Clockworkmod - stuck at S logo after

Hi guys.
My phone is a international i9300
I've been searching for a problem like mine in the forum for three weeks now and I couldn't find a proper solution.
I just can't flash any rom via CWM anymore...
I can flash roms via ODIN, but when it comes to CWM, it gets stucked at Samsung logo after the install.
I tried:
Wipe cache / Dalvik / factory reset.
before the installation, after the installation, every combination possible.
Tried megawipe and no help.
Changed the kernel, Siyah, Googy, stock...
Changed versions of CWM, touch.
I have now the Phil'z 5.0.15.
I like very much the XXELK4 version from roalex with its MOD, for the call recording and full multiwindow support, but can't flash it anymore, nor any other custom or stock via CWM.
By now I can only have a full stock flashed via odin, or my Omega 46.1, wich I have a full backup.
Another solution could be find a .tar rooted and with the MODS flashable via Odin, but I really wanted to understand what's happening with my recovery.
Thank you all and congrats for the great work with the forum.
In cwm format..
Data
System
Cache
Then go to advanced and wipe dalvik cache
Then flash the rom.
Your cwm is upto date?

Sorry.
Forgot to include in the original post... I tried that too. Formatted everything
Got the 6.0.6.3
I also tried with the last Philz recovery.
And with previous versions of both too.
Have you tried to go bk to stock,root that firmware then install cwm then flash custom rom? Clean slate start.
Your problem may be a bad file download .

I'll try to download again, although it's not likely that several files are bad. I tried with so many different roms...
I bought another micro sd of 64gb. Maybe the one I'm using is ruining the files...
There can't be a so huge bug in philz recovery
Try install from internal sdcard, a simple 'Factory Reset before New Rom' no need to mega wipe anything.

Of course. And I tried with different versions of Philz' and also CWM. It can't be a bug in recovery.
Re-downloaded the revolution 29.0 and the Roalex XXELK4 rooted, copyed directly to internal and flashed... Same problem. Stuck at Samsung logo in boot. I'm begining to think my phone is screwed up. But this is so strange. I can restore my backup with no problems, and also can flash with Odin.
Is there a way to flash a .ZIP ROM in Odin?
Does not make any sense .
What model phone do you have ???
What model firmware are you flashing .
What about basic stock custom roms flashed via CWM ??
Have you booted to Philz recovery mounts and storage format sd card cache system and data then flash rom ??
Agree it is strange Deviating a little from your problem but have you tried flashing anything with TWRP recovery see if the problem persists with that.

I know it doesn't. That's why I'm going crazy.
I uploaded the screenshots with my system specs.
The model is correct, international i9300. Tried to download from the site and also directly from rommanager.
The firmwares I'm trying to flash are stock, but rooted by Roalex. I couldn't find a pure stock .zip for testing with CWM. The firmware I'm using is UBEMH5 from sammobile, wich I flashed via Odin.
Yes... Tried and formatted everything, several times, mounted, unmounted, every possible order...
Almost giving up. :crying:

I never used TWRP. Can I flash the same ROM file .zip with it or it requires it's own rom file type?
I'm gonna be out of the country for two days. When I come back I'll give it a try.
Thank you all so far.

It's been a while since i used it last time was when I had a S2 and I used it all the time:good: You can flash any rom with it that cwm can flash (as far as I know) but it had a little trouble restoring backups made with cwm but I think that got fixed.But you can make backups and loads of other things with it I recommend people to try it at least once This won't fix your cwm problem but would be interesting to see if it works
If twrp doesn't work on stock Flash googy Max dualboot kernel and keep stock as primary rom and custom as second rom. Then you have best of both world's :thumbup: also take the pic down with your emei showing :banghead: never ever show this!
What i would do in this situation is .
In recovery format cache system sd card preload .
Flash stock rom via Odin.
Check phone works ok .
Then root / flash philz recovery .
Put custom rom on sd card boot to recovery factory reset .
Then install custom rom watching setup to spot a failure point .
Wait for rom to load 10 mins fails then remove batter replace and factory reset .
Problem solved
Hi folks.
Think I figured out what's going on.
Via TWRP it says the files were corrupted, although the file sizes were identical.
I MD5 checked the files in my computer and they're ok, but when checked already inside my phone or SD they're not.
Instead of copying the files via USB cable I removed the SD card and inserted directly in my laptop slot and copyed the files. MD5 checked and they're ok...
After I tryed again copy via USB and the files were corrupted again.
I think my desktop USB or maybe the Samsung drivers are doing that.
Well, problem solved. I hope this helps other people in future problems.
Thank you all for your help and support. Keep on with the great work.
Mark solved then for other users .

Wipe data

Flash stock sammy rom with odin.
If wiping data doesnt work, try flashing kernel. If that doesn't work, flash stock 4.1.2 via odin

i just installed the stock firmware which is 4.1.2 and then tried wipe but theres a message in the system recovery says failed to mount /efs? any clue? thanks in advance.
flash latest philz kernel from here http://forum.xda-developers.com/showthread.php?t=1877270 ,boot to recovery,then restore your efs backup from there(you should have one in your external sd)
Sent from my blazing fast Note 2, running MIUI 5x and pleasantly surprised by it.
just installed philz kernel and went to recovery im searching for restoring the efs but cant find it though. still on bootloop.
i think this phone has other problem already tried 3 different stock firmware for this phone and then go to recovery wipe still on bootloop. tried installing kernel from philz its desame but only thing i noticed is every time i installed a new rom and go to recovery is says failed to mount efs. can it be one of the reason why its on boot loop? and also my friend didnt back up his efs thats why i think this is happening.
do you have a nandroid backup of any previous rom?
yup he has nandroid backup which has on the stock rom but i doubt cause when i installed the stocked rom then installed philz cwm which was 6.0.2.7 i was able to restore the back up but its still on bootloop so i dont know if the cwm is the ones not compatible or the rom.
after you restore your backup do a factory reset in cwm.
now i tried what you said and its showing md5 mismatch when i try to restore.
could be a corrupted backup.did you tried factory reset on your current rom?
argghh im on the blink on giving up on this phone already tried different methods.............
assuming you're now on stock 4.1.2,i suggest you to flash dorimanx 8.43 kernel,,if it doesnt boot,reboot to recovery,do a factory reset.If that doesnt help,try to restore nandroid from this cwm.Of course before restoring do a factory reset and format system and preload partitions.
ayt will try this now!!!
still no luck not working T_T..
you mean you can't restore your backup?And dont forget to wipe cache and dalvik cache when doing factory reset.As for efs,did you looked for it in internal sd too,in clockwork folder?It can be either in tar.gz,img.gz or zip formats.It's stuck at boot probably because of corrupted efs partition.If I remember well,you can restore efs partition from nandroid backup in philz touch cwm.
Have you done a stock samsung rom install usin odin? That should get you back to sqaure 1. If your backup is currupt it will never work.
