[Q] no boot after Samsung update - Galaxy S III Q&A, Help & Troubleshooting

Hey guys its been since my first epic 1 that I been here..what I have is an unrooted s3 I updated it and it worked fine but the next day it wont boot past the big s....I was wondering if anyway to undo the update? I dont want to wipe and flash because all my pics and music and some important files that mever made it to my sd card..any help or idea?

Boot to recovery and clear cache and dalvic, probably won't help though.
Next step is always to factory reset, you might get around this by installing custom recovery (Philz recovery is recommended), use that to format system, data etc. before installing your previous stock rom via .zip. That way your internal sd files will still be there and the phone will boot.
Follow guides in general, stickies.

Ok but it wont let me in recovery mode.I can get into the odin but thats it.can I dl cwm to it from the comp in odin mode? Or do I have to root it from there and see what it does?

from the odin mode flash stock rom as per your region. Also please note you will loose your data.

wiping error

iv been having a few issues as of late with my s2 so decided id just backup my numbers and media and wipe and start again, but when i do a factory reset, it shows an error mounting the sdcard/.android_secure
and then it skips it, can anyone tell me how to fix this problem so i can start a fresh with a nice clean and empty galaxy
What system do you have? ics or ginbread...?
Question = wrong forum.
....................................
Clean Slate for those that balls up the firmware .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card .
Remove battery
Boot to download mode
Open Odin
Install correct stock firmware .
jje
my apologies, i havent used the forum much as the phone has been fine for about 6 months, its now on checkroms v6 which i managed to flash onto it with a bit of fiddling, thinking that may solve some of my issues but it didnt. thats when i noticed this error when doing a few resets.
JJEgan, gonna follow your steps now buddy, thanks and fingers crossed
its a no go, it wont let me format or mount the sdcard
try factory reset from phone menu,
try another kernel to get another version of CWM, eg: Siyah
hiya zac, well i have the phone in download mode connected to odin, im using the link in your sig, and downloading the stock firmare and kernal, will it matter if i didnt wipe the sdcard before flashing these two items with odin? surely i can do it after?
upto you to try.....
cant guarantee since dont know what weird problem has got with your SD card which
dont allow you to wipe,
you can also try flashing another custom kernel first,
When you flash a stock firmware it already contains a Kernel, no need to flash seperately..
any chance to a quick link to a kernal to try and a guide!
its been a while since iv done this! haha
which rom are you currently on?? ICS or GB
checkrom v6 i do believe
GB CWM flash : http://gokhanmoral.desean.net/siyahkernel/v2.6/Siyah-v2.6.14-CWM.zip
Checkrom is GB version,
but makesure, from settings/about phone
i will bud, and i flash that kernal, with odin?
no this is CWM flashable, put on SDcard, and flash from CWM,
top man, off to have a go now
if CWM flash fails, you can try from ODIN
ODIN flash :http://gokhanmoral.desean.net/siyahkernel/v2.6/Siyah-v2.6.14.tar
select the file from PDA of Odin,

Unless you have a external sdcard, this problem is self explanatory!

[Q] Stuck on bootscreen

Hey,
First off i hope i have put this on the right sub forum.
I've been stupid (I Think) I've olso looked around on the forum and the [READ THIS] Got a Boot Loop? Don't post a New Thread!
topic.
I'm using my SGS2 for a year now and was using the ressurexionRimix rom for a while.
I've been plaing around with my phone so i got lots of folder that were not used etc, so I wanted to get it back to factory settings, here is when all went down.
Via Settings-Backup and recovery i gave my phone a factory reset (while using the latest ressurexionremix rom, i think this is the misstake i made) When my phone went into the reboot is got stuck on the splash screen, it kept reapeeting the boot animation.
The second mistake i mad was not puting back my back-up but thought well i want it back to it's first state so i'll use ODIN to flash the stock ROM onto it. now, 4 hours later and about 10 trys with diferent versions of the stock roms i'm still stuck on the boot screen.
I've also tryd flashing a cwm so i could get in cwm recovery, this also without any luck
Does anyone have a idea what to do!?
go back to recovery - mounts andstorage and format the following :
cache, system, data, sdcards if you have it in recovery. reboot
you have a bkank screen as your phone has been wiped. reboot into download mode.
Connect odin and flash a stock rom. reboot and your phone should work provided that you have not damaged the flash chip on the motherboard.
Is this in CWM? the problem is i dont have that anymore because i've flashed it toc stok. I now get in the Android system recovery
The option i get there ar:
Reboot system now
apply update from external storage
Wype data/factory reset
Wipe cache parition
apply update from cash
test redbend fola[FS]
Will try this, thank..will let you know if it worked
Wiped data/factory reset and cache after this i ebooted my phone and i got the message installing application, now i'm in the setup menu. Looks like it is working.
Did'nt realice there was a recovery besides CWM Thank yoy so much Cosmic Blue!!! You saved my life!!

HELP!!!

Ok here's the problem. I rooted my phone the new Galaxy Centura from Straight Talk. I then proceeded to wipe the Dalvik Cache. When I was looking at the other sections in recovery, I ended up in the system format. I really didn't mean too but I did format the system. My phone will still go into download and recovery modes and the Samsung image still shows up but nothing else. Is there a way to fix it? I have to know. Please help. I need it desperately.:crying:
At this point you should flash a custom ROM through recovery or if needed use hiemdall or Odin to return to stock in download mode

Just (also wipe data), download some ROM for Your device and flash it via CWM.
Or You can always download ROM for Your device from here and flash it via odin. It's the easiest way to fix it

[Q] Bootlooping - need quick advice

Updgraded to Jelly Bean 4.1.2 via Kies. Un-rooted, stock SGH-I777. Stuck in bootloop now at AT&T logo. I already did the wipe data cache in recovery mode with no luck so it leaves me to factory reset as my next option. I've spent several hours browsing through the forum already. Do any of the below allow me to keep data?
1) Use Odin and stock firmware - downloaded the UCMD8 tar file
2) Root, install kernel w/ CWM to use backup functionality. (http://forum.xda-developers.com/showthread.php?t=1285894)
Just need a point in the direction I need to go, I'll handle the rest.
If the result is all the same (i.e. data loss), I'll use this issue as an opportunity to put a custom ROM on my phone.
Thanks!
Yes, most likely a wipe data/factory reset performed in recovery would correct the problem, but you will lose some system data. Which specific things are you worried about losing? You won't lose your photos, or any data from applications installed from the play store.
You are going to have to perform a wipe data/factory reset to use odin and the stock UCMD8 firmware. In fact, at this point it is probably the only way out.
U could try to re Odin the firmware first. Not sure where ya got it from, but it should be a no wipe. But if that doesn't solve ur problem, then ya have a few options--- Odin a custom kernel (like AJK), and then u could Mount usb storage through recovery and backup ur stuff to ur pc. Then try to see if it will boot up without looping. If it still loops then u need to go back into recovery and wipe data/factory reset. Reboot. And it should be good. Or if ya don't care about ur data, then just reboot to recovery and wipe data and reboot.

mostly just concerned with losing SMS but i have a backup from a few weeks ago so im not out much.
thanks for the answers! I guess i'll just have to make the plunge on one of the options.
