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.
Hello Everyone,
Just brought used Samsung I9200 but it is acting strange.... When i start it, it is showing Samsung Galaxy I9200 and when i install any Stock 4.4.2 on it, it get stuck in reboot loop. Then when i flash recovery, custom rom after rooting it from recovery it boot fine but in IMEI it is showing 0
I installed and tested many device info apps from market and it is showing model as I9205. Is this mean it is I9205 and someone in past loaded i9200 rom thats why it is in reboot loop? I flashed 3 different stock roms ie; from russia, saudi arabia and uae but with every of these i9200 rom it never boot and always get stuck in reboot loop even recovery is not accessible during reboot loop but download mode can. So, when it get stuck in reboot loop i always do recovery, rooting and then custom rom. But, IMEI is 0 with no phone calls and No SMS actually no network at all. Even the sticker under the battery is not clear showing IMEI or model correctly
Some help will be really appreciated...

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.

i have tryed flashing modem but odin is unable to flash modem and sboot
it flashes system ,recovery
the baseband is known only imei displays null/null
also i hav noticed my phon gets warm and drains batery when it is on sleep
it drains 3% evry 15 min when i don't use the phone
Hope someone can help me here . First when I bought my phone I'm sure it is a gt 9300 I succeeded at rooting it but never flashing a costum recovery (I tried Odin ,flashify ..everything ) the phone just didn't boot into recovery even the stock one so I thought the bootloader maybe is locked so I used an app to unlock it (don't remember which ) but it just hard bricked it .so I take it to a repair shop they try everything but the phone don't boot so they change the motherboard which lead to my problem now .I rooted the phone again but I still can't boot into recovery even stock one and the thing is I noticed that in the download mode screen it's written that this phone is a sgh 1747 but when I start the phone it shows gt 9300 even in the about phone section
So which one is it ?
So no one has an idea bout this .
Well I succeeded at flashing a custom recovery .I used a sgh 1747 one .I guess I should flash a custom 1757 rom too.
The model number in download is the model number for the motherboard and associated components. If the model is sgh-i747, the motherboard is from an at&t s3.
I9300 has 1gb of ram. The rest have 1.5gb of ram.
