flash a stock rom in Odin, factory reset from recovery. it's all in the stickies
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.
I tried so many times to install custom on this phone but with no luck to get it to work...when installing with odin everything is good i get no errors or any thing bad just when the phone restarts and tries to acess custom recovery the phone restarts again...after that every time i try to access the custom recovery the phone restarts again...i have to flash my original frimware again to get acess to the original recovery...i'm still on android 4.3 and did not upgrade so if anyone can help...i'll really appreciate it
Sorry for my bad english
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.
Hi guys,
Got a tricky one here - a friends just brought me a Galaxy S2 thats stuck in a boot loop but tells me he's got years of photos on it's internal memory and not backed up
So far I've managed to get it into download/recovery mode, tried a cache reset and got nowhere now I'm a bit stuck. Do I:
Do a factory reset - I'm told it doesn't delete the users data, but some people say it does and I can't risk it until I know for sure.
Flash a stock ROM - Apparently Odin (Which I have got running and can see the phone) can write a ROM without losing data - but again I'm weary of doing so without a definite answer.
Something else? - Possible to write just a custom recovery and mount internal to USB or something? Tried TWRP but it fails in Odin.
Any help is greatly appreciated guys, from both of us!
Can you access the phone through ADB while in recovery mode? (Maybe you'll first have to install a custom recovery with Odin.) Then you can just use ADB to pull any files you want off the phone.
