I've flashed the Stock ROM for my phone 3 times (I think it's Vodafone for UK - but not 100% sure)..

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.

Reboots to set things up, gets halfway then reboots and gets stuck in a reboot loop with this on the screen -


Feels like the /data partition is screwed beyond repair, but I'm hoping not. Can I recreate it somehow?

Thinking this phone needs a new EMMC, but I do not understand why this happens -

(Yes, I added the PIT this time).

All goes as it should. No complaining until it reboots.
Still stuck at Android on his back with Red Triangle Warning.

This phone has been a mission.

I've just run it all again, this time, with Erase NAND selected. I figured it was do or die time... Data wouldn't format no matter what I tried so figured wipe out the NAND completely and try to recreate the partitions...

WIN! Phones is back in one piece working a treat. Odd problem, but glad I documented everything I did here. Maybe it'll help others in the future.
Installed Philz Custom Recovery, and ARHDv51. All working perfectly now.
