wipe cache... thats not really recovery not working, thats just saying it cant access a log file you will never actually use

 

jb 4.2 cant, that would be cm10.1 or jellybeer or something like that, the 4.1 jellybean update however should read an sd just fine. the only fully functional custom roms are ics based, Awesome Android, SuperRom, and Cyanoid are the main three i am aware of

 

you could try this b11 stock rom. It has all the bloatware removed so it's about as vanilla as this phone gets.

 

i wasnt aware megatron was even out. there are roms around, but few are b11 based

 

.

 

yea if you flashed megatron it was for the wrong device, which would certainly explain your current "total wipe" issues over in your other thread

 

Moved this thread over to the all-things-root area for you .

Thanks!
