Desperately Need Help on Original China Unicom Firmware - Galaxy S III Q&A, Help & Troubleshooting

I just return from trip in China
I bought a S3 just before getting on the metro to the airport. the model is GT-I9300_CHN_CU
After getting back, I realized that I am not able to install a great many app, and the google play store is missing.
After numerous attempt to download and install the play store apk, which I am not able to get it to work
I try flashing it with a UK version ROM with Odin3 v3.04, however just before the last part, while writing the modem part, Odin report the operation as a failure
Now I am stuck with "Firmware upgrade enountered an issue. Please select recovery mode in Kies & Try again" on the main screen.
I did not backup with Kies earlier so I am not able to perform recovery
I am trying to find the firmware for the China Model SIII, can anyone help me by pointing to the location where I can download the origonal and correct formware to get it running again ......:crying:
I am really an amature on this.
thanks for the assistance

Thanks it WORKS!!!

mobile odin
Hi mate i also have a china unicom samsung s3. i changed my firmware to the latest polish jelly bean 4.1.2 using mobile odin pro which i got from the chinese samsung apps store and it worked like a charm. using normal odin messes up the unicom boot loader partition. that is how you bricked your phone.
my phone now boots with the unicom logo and then shows the european galaxy logo ....
also you might want to check titanium backup pro which i got for play store for backing up your phone and applications. its great !!!!

HELP!! tried to root and not sure what i have done wrong :(

my phone is a samsung galaxy s2 which was is branded to orange.
i have recently updated from android 2.4.6 to the new android 4.0.3 through kies.
i was really wanting to just root my device but for the time being leave the current rom on, i mainly wanted to uninstall blatware for now and backup etc...
anyway things have gone a bit wrong, i tried following the beginners guide on the following url:
http://forum.xda-developers.com/showthread.php?t=1056334
i downloaded the files that it tells you to, i opened odin and selected the XWKDD file as it says to and it said that the root was sucessful, but my phone didn't fully reboot, it went off and come onwith the samsung galaxy s2 logo and a yellow ! under it, and now it just stays on that and wont do anything else
have i ruined my phone or can it be fixed without losing any of my data or the way i had my phone?
any really fast help would be great, id love to sort this tonight if i can.

Did you even read the tutorial??, there clearly states where to download the files,
thats why you bricked your phone, you have to readdd everything and understand things before going up
I hope this options works for you !!
Hey, read this options to solve this problem. The second option Worked for me
1. if you´re phone doesn´t turn on and the screen not response maybe the problem is a hardbrick,
2.if you´re galaxy doesnt turn on but in the screen appears icons, the trouble is softbrick.
1.The solution for a hardbrick is a JTAG, this is a used method by Tecnics
2. The solution for a softbrick is a reinstall , just put the galaxy in download mode and install a official firmware with odin and done
after downloading a pit file it works
thank you very much

Help please tonight with s3 :(

Hey guys,
First of all sorry for caps lock but it's really urgent. I had CM on my S3 I9300 and I tried to flash 4.0.4 stock ROM that i downloaded from Sammobile. It installed normaly but when the phone restarded after instalation, it got stuch at Samsung logo screen. I restored it to CM that i have previously backed up. After that i have no service, Odin can't recognize my phone. The biggest problem is that i have no service. It says it is Registered on Network but when i try to call someone it says Mobile network not available. When i try to send a message it says that it can't send it and it will send it when service becomes available. Pleasee guys help ! I need this to be fixed ASAP.
Thanks in advance !

Flash back to 4.3 stock rom with Odin you where on efs v2 and have flashed stock 4.0.4 which is efs v1 your phone can't read your modem. Read this >> http://forum.xda-developers.com/galaxy-s3/general/ref-imei-efs-stuff-i9300-including-t2393289 << You cannot downgrade to 4.0.4. without a efs backup made when and if you where on 4.0.4 or 4.1.

Samsung on5 Stuck with Custom Firmware blocked by FRP

I am new to androids and bought the phone hoping to root it and use it with automate for cycling airplane mode.
I used odin, insted the twrp package and it was rooted. I added my refill card to tmobile and when i rebooted this happened.
I have been reading and lookign for a solution and i can't find one. I've downloaded a bunch of files tryign to find the original firmware but nothign seems to work when written with odin.
Can the tmobile store reset this? or is this phone just trash?
Thanks for any help. Sorry for being a rookie.

S6 Edge Black Screen after install new rom, please help!

Hi, i need a little help.
i'm order a samsung s6 edge phone today, seller said installed android 7 rom to phone, when factory reset the phone. screen go to black. and not working.
- Leds working on the phone.
- Touch screen working
- can listen music from phone
connected to pc, (pc found a new driver and found the phone), oddin found the phone and can install new rom.
Maybe any one can help me ?
Really thanks!
Most probably, you should flash a new kernel compatible with Nougat with Odin. However, in my opinion, the best idea will be installing Samsung Kies and use Tools -> Emergency firmware recovery. Be sure that you have a backup of your pictures and other documents before doing it!
