All completes and Odin says successful. I reboot and my phone doesn't get past the first 'Samsung Galaxy SIII GT-I9300' logo. I've flashed and rooted many phones in the past, including both my sons S3's, my daughters S3 (this one) and my HTC One M7.
I've re-rooted the phone (so recovery.img installs) and I can load Philz Recovery on it no problem - CWM or TWRP better for this situation?
My findings manually in Philz Recovery so far...
Formatting /system - Works OK
Formatting /cache - Works OK
Formatting /preload - Works OK
Formatting /data - Reboots phone almost instantly.
unmount /data -> Formatting /data - reboots phone almost instantly.
When I try to install a custom ROM 'Formatting /data' reboots the phone and I'm stuck at the Sammy logo again.
Is my /data partition screwed? Is there a way to check?
I want to make certain because I do not want to use a PIT file unless it is the last resort. Is there an alternative route.
Re partition just /data perhaps using adb?
After installing the Stock ROM I cannot get into Stock Recovery, but if I root, I can get into custom recovery.
Odin/Download mode working fine still.
Very odd... Any pointers?
Any assistance hugely appreciated.
