Hi xda , i have this china-bought Galaxy S3 GT-I9300.
It started out with gps not working and i tried to flash a stock rom using odin (device was rooted) and it failed after countless flashings.
And then whenever I tried to boot the device again it was stuck at the ''Samsung GALAXY SIII GT-I9300'' screen. not sure if it was a bootloop but it was just hanged there. I have cwm recovery mode but i can't access download mode however i tried. And all of my computers cant seem to detect the device. so basically the thing i am able to access now is the cwm recovery mode. i tried various roms but to no avail.(they all hanged while installing system files)
Some specs about this device i know:
- Board : uniscope77_bu3_cu_ics2
- CPU : armeabi-v7a
some additional info : i once formatted everything on the device using cwm (internal storage , system , everything)
-I tried reset to factory settings countless times too but they were all stuck at the ''Samsung GALAXY SIII GT-I9300'' screen.
-Its original stock firmware was from china and yes , ive tried using china stock rom and all i get was blahblahblah and a ''(bad)'' thing.
if you need anything else like what other things i did to the device pls tell me. pls help me solve this problem thanks you ^_^

Where did you bought it?
China
your screwed the only thing you can do is download Chn_Chn Firmware from Samsungs website and flash it though odin. And that's the only fimrware that will work, unless you flash a custom bootloader through your sd card as then it will overwrite the encrypted boot.img allowing you flash any European Firmware.

*Urgent* Bricked S3(gt9300)? Accidentally wiped my s3 (in allianz rom bootloader screen) .* It then vomplrtely wouldn't work, so I used odin to put a stock rom on (via pda)* Success ! working completely fine until it lost power & will only ever get as far as the samsung logo when turned on. Need urgent diy help to get my phone working again,* I have tried a number of how-to's on fixung a bricked s3 via odin with no luck!* the error message is along the lines of no partion available & will fail no longer than 2 seconds into process. no matter what rom ; custom or stock Im unable to fix.* My guess would be that ive deleted whatever software in phone that would recognise a rom. Notes: I am competant in use of android just very good at making mistakes.* The only feature available is the download usb mode. Any help would be appreciated especially if it works, Im sure someone else has had the same problem!
Hi XDA members, I came here because I'm tired and I cant'd do anything more, I need help
Ok so first I had a Samsung Galaxy Core Duos GTI8262, original, no modified, android 4.1.2, everything all right.
Then I starded to try to install a costum ROM with 4.4. I rooted it, and then I found a CMW Recovery and I had installed it via Odin307, but it didn't work because it was not compatible with my phone, it was crashing all the time and the phone used to make noises, like an engine working or something, and then it shuts down. Then after much search I found here in XDA a costum Recovery Based in CMW for my phone, "CMW based Recovery v6.0.4.7".
I installed it via Odin307 under the previous CMW that dint work properly, and finally everething went all right, I installed a ROM with KitCat, then another with Lillicop, etc... then I wanted to try Cynogen, it was in my model devolopment and I installed it, bigger mistake, it didn't recognize SIM card such as Wifi, Bluethoth, etc... no conections. I get tired because with all my Download mode started to get stuck, so, I could not install another ROM, so, angry, I went to based CMW Recovery and I formatted EVERYTHING, until get to the point where there wasn't ANY file in SDCARD0, I tried to make factory Reset, didn't work, so I turn the phone On and the logo "Galaxy Core Duos GTI8262" stays there forever... the phone doesn't start.
THEEN... i downloaded the stock ROM here in XDA to my model (I'm Portuguese (Portugal)), and tried to install it via Odin207. I was waiting that the Download Mode got stucked again but I tried it in the same way, because I didn't knew what to do more. BUT, instead of get stuck, the Download Mode only stays for aprox. 5 seconds, then the phone shuts down... SO > nothing in SDCARD0 (and the CWM Based doesn't have the option to install anything in extSDCard I dont know why...) and Download Mode crashes... without pay nothing, WHAT CAN I DO PEOPLE? :crying:
Please help, sorry my English...

I have tried everything on YouTube videos and on other forums, and nothing has worked so far... This is what has happened:
1) I flashed a custom font zip file, which I later realised was only for the HTC One M8
2) As phone rebooted, got stuck at the "glowing" Samsung logo (the 3rd one, after the model number and the jingle)
3) Phone stuck at that logo, have tried LOADS OF METHODS and nothing has worked
Please help!
PS - I am new to these things and have rarely "dabbled" in this kind of stuff, all I've done so far (which worked fine) is root my phone, install CWM Recovery, install a modded version of Android 4.3 (?) which was designed to make your phone run faster (which it did). Please help! Have I broken my phone?! :crying:
Search for the latest stock ROM for your phone on sammobile.com and flash the ROM using Odin.
Some good info here too: http://forum.xda-developers.com/galaxy-s3/general/samsung-galaxy-s3-sticky-roll-thread-t2344125

So from yesterday my phone is stucked on a bootloop ... i didn't installed anything in the last days, i didn't installed anyupdate.
I tried to install stock firmware via odin but i'm still on bootloop ...
Before installing stock firmware my phone was booting until android .. it showed Android is optimizing app x from xx and then rebooting and doing the same thing ..
After intalling stock my phone is restarting after Galaxy s6 edge - powered by android logo.
I've looked into this forum and tried to solve how others solved,but nothings work ...
Anyone knows how to solve this?
I tried to flash custom rom but i cannot copy on internal storage via twrp ... and i dunno also how to solve this ...

Factory reset from recovery.
Sent from my SM-N920C
i did that ... same
Problem solved with JTAG repair.
Can you describe in details?

When a phone is in a hard-bricked state it’s most likely that the bootloaders, which is the phones initial code to launch the phones ROM, becomes corrupted.
The only way to revive the phone is to rewrite the bootloader code.
So basically, if you can't flash a rom through twrp or odin, this service we'll rewrite the os from scratch without having any acces to phone.
