[Q] Help with flashing custom ROM
1st post here at xda. I have a s3 running 4.12 , stock rom vodafone in ireland.
I installed CWM and rooted phone. Then done a backup with CWM.
I tried to install R5 stock rom from internal sd card, i selected the zip file and the installation started but had an error
i coulnd;t see.
At this stage i panicked a bit. I tried again but wiped internal sdcard in CWM before i started.
Now the phone wont boot to any OS (since tried to install 2 other custom roms from xda, both times screnn went blank after choosing installation options)
Cant recover backup as its no longer on internal sd card.
I can access CWM. Should I start by installing stock rom from samsung site ?
Am I doing the custom rom installation correct by using CWM to install from zip file in sd card ?
I tried to install roms with odin but its looking for tar file ?
thanks for reading,
