[Q] Downgrading to 4.3 from 4.4.2 - Galaxy S III Q&A, Help & Troubleshooting

Hi,
Yesterday I have updated my Galaxy S3 I9300 to Kitkat 4.4.2 using a custom ROM. While I wasn't satisfied with the performance of that custom ROM, I have downloaded the Stock 4.3 firmware and tried to downgrade it using ODIN.
All went smoothly till my S3 stuck on Samsung Logo while rebooting with 4.3 installed. It does nothing now except stuck on the Samsung Logo.
I am afraid that I did brick my phone.
Any help will be highly appreciated as I need my phone back to work urgently
Thanks...

Yes you can.
If you flashed with Odin, you will now have stock recovery. Boot into it by using power+home+volume up. And choose 'wipe data/factory reset' from the menu.
This WILL wipe your internal storage too, but since your phone isn't booting there isn't much you can do about that.

[Q] Trying to restore to ATT stock, locks at ATT "rethink..." screen

Hello all, could use some help here.
I'm trying to restore my Note to the factory ROM and I'm running into an issue.
Fyi, I had the latest Paranoid JB Rom from Oct 13.
I followed the proceedures outlined in the forums (used ODIN to restore the default "attstockrom") and after that restore the phone would loop rebooting into ATT rethink possible animation screen.
I found and downloaded the latest 4.04 rom for the phone (I717UCLF6) and rebooted. Now it just hangs at the "ATT Rethink possible" graphic (no animation, no loop).
Odin does see the device fine so I can reflash again with no problems if I need to. I'm thinking of trying the I717UCLA1 version from Jan to see if that works but I'm hoping I can get some better advice before I do something that might cause more permanent problems.
Any advice on how to get back to stock ICS (or even JB) and get the phone working again?
Thanks!
Try doing a factory data/cache wipe from Recovery.
I flashed the stock rom via ODIN. There is no factory data/cache wipe since there's no custom recovery.
Are you suggesting flashing CWM/TWRP on the phone now then doing that?
Houston we have liftoff. Thanks for the tip Fappa, that got me into the phone (reinstalled cwm, factory reset). However I'd still like to remove CWM and go back to completely stock....
I'm not overly worried about it as I'm selling the phone but I'd like the new owner to have a completely clean phone in case they need to send it in at some point for repair. But in any case it's up and running with CWM and factory ICS rom.

I'm sure fappa meant to use the stock android recovery and wipe. when I go back to stock it always hangs at AT&T boot logo and have to wipe/reset from stock recovery to get it to boot.

Yes do what they say or you will continue to boot loop.

S2 won't go past boot screen

So basically my S2 died on me randomly, but i was able to boot into recovery so i tried to restore my backup. It then said 'MD5 mismatch', I then tried to install a rom but it said installation aborted, I then booted my phone into download mode, loaded a stock rom through odin, it said successful but it won't go past the boot screen, it just hangs. I tried flashing another stock rom but the same problem occurred.
Any form of help is appreciated
OK now you flashed back to stock rom, boot into stock recovery then do a factory reset/wipe data. Be sure your not dangered by the emmc bug on 4.0.4.

Thanks that helped, the phone booted up fine. I guess I panicked.
Now to see if it will work with the infuse 4g dock.

Have i bricked my phone?

So I installed stock rom 4.1.2, by deleting caches, and factory reset. then i used odin and flashed the rom. I had cm10 earlier.
Now when i turn my phone on it just shows the spinning thingy that turns into the samsung logo. The led flashes blue all the time. I can't do anything.
Try factory reseting from the stock recovery or if you do not want to loose your data flash a clockworkmod recovery then factory reset

[Q] How to recover when itmpossible to wipe data/factory?

Hi,
Tried flashing firefoxos on my S2 (i9100) and now I'm stuck in boot loop.
I've tried a multitude of tricks to no avail.
Basically I'm able to flash any kernel or rom. Currently I have CWM 6.0.3.7 and CM 10.2 flashed.
I'm stuck at the splash screen.
If I try to wipe data/factor the phone sits for a while and then all of a sudden it reboots.
Any suggestions on how I can revive the phone?
EDIT:
Seems I might've been bitten by the MMC Superbrick bug,.. Can someone confirm this?

Your phone is totally safe as long as you are able to boot into recovery.
Download any jb based custom ROM and transfer it to your phone by mounting USB storage in recovery.
Do a full wipe
Flash it.

Problem is when wiping..
I just installed CM 10.1.3 (Stable) via CWM, no issues.
But while formatting /data (After quite a while) the phone just reboots.
Flash stock firmware with Odin.
I tried flashing stock firmware using odin but it still hangs during the samsung logo.
Has this phone been hit by the EMMC brick bug?
Is there anything else I can try in order to revive it?
