I decided to upgared the ROM. It has SPL-2.08.0000
I downloaded the latest ROM from T Mobile 2.13.531.1 and went into boot loader connected USB it dispayed USB (i.e changed from Serial). I started after it was done 8 pct it stopped.
I also tried putting NBH directly into the sd card with leoimg.nbh but it is just displaying "upgrade rom error code"
Please help as what should I do next.
