Go to www.sammobile.com to find the firmware and flash through Odin. Make sure you don't tick repartition or use a pit file unless you know 100 % what you're doing.

Debrand and Root help

Hi,
Sorry if this has been posted before i am a bit of noob on android.
I have got myself Galaxy S3 locked to Three network i have looked all over the forums but managed to confuse myself
I want to debrand and root my phone but i don't know what to do first do i root before flashing stock to the phone or flash with stock first then root.I really don't want to brick it lol.
I would like to open it for all networks also.
P.S Im in UK model number GT-I9300
Thank you
Steveo
First u have to flash the debranded firmware you want with Odin theN do a cf root then after u have rooted you can go to play store and download voodoo galaxy s III sim unlock
If I helped say thanks
Hi
Thanks for the quick reply.
So do i just flash the stock rom for the uk straight to my phone using odin3 v1.85?
will it wipe everything from my phone once i do this contacts etc..
Stock rom does not wipe .
Root will be wiped if you flash stock rom after root so in your case stock followed by root .
jje
Thanks for the help guys.
I managed to get their in the end.
what did you do in the end ? I want to do the same and remove the Vodafone branded firmware off my S3 and just add stock firmware on..
Cheers
Go to samfirmware.com and flash your Rom of choice through Odin.

Download Odin (can be found in this forum)
Download your stock firmware 2.3.6 (I dont know about the CHN_CHN Version)
Put your phone into Download Mode. (Power Off, Hold volume down+home+power button)
Run Odin
Choose PDA file which is your stock firmware.
Flash

Use search.. You will find lots of topics,, Anyways, following link will guide you :
http://forum.xda-developers.com/showthread.php?t=1110160
IMPORTANT : While choosing model from the dropdown on Checkfusdownloader, choose "GT-I9100G"... Do not choose "GT-I9100".
相信你是个中国人,要不然应该不能买到中国版的9100G。

I tried this before when I first flashed to CM9, I get bootloops. Since then, I forever stick to ICS and never trying to convert back to GB although I wish to do so. I dare not and i'm lazy to deal with the bootloops.. I not sure why I get bootloops btw, some other ppl faced that as well. So I hope this brother able to convert back to GB successfully. Good luck.
To convert back to GB you have to flash an old GB bootloader for some reason after flashing the stock ROM. After that do a full wipe, everything else ended up in a bootloop for me.
Fingers crossed .

I can flash GB stock GDZKL3 after flashing this bootloader right? bootloader should flash before flashing rom, or after flashing the rom? Thanks.
I tried both options. Try flashing the bootloader at first but don't forget to uncheck "Auto-Reboot" in odin. After that you should be able to flash the stock GB ROM. Do you have a jig just in case of any problems? I remember I used my jig, but don't really know why.

What is Needed to Update ICS ?

Hi, I would like to use Custom ROM for my S2, but I'm afraid there's some error when I use the ROM and Kernel.
What should I prepare before some error is occurred ?
I never update to ICS, so I don't know which one the StockROM is.
Anyone could help me ?
Thanks.
Hi,
you need to read the guides :good:

Read some guides for odin. Then go to www.sammobile.com and download a stock firmware and flash through odin, there's some ics firmware on the site.
Or you can root your device and flash a custom rom through cwm recovery.
