http://forum.xda-developers.com – hey guys, Last night I was trying to unroot my IncS and now I am stuck at fastboot. I have searched a lot but not getting any good answer. I was revolutionary s-off and on blackrose hboot-2.00.0002 The steps that I followed, downloaded ICS WWE RUU. got rom.zip made PG32IMG.zip and flashed via bootloader. I got the stock ROM and it booted fine. till now everything was right. But now to remove blackrose hboot, I use blackrose installer only and it actually installed hboot-1.13. as far as I know ICS can't bootup with it. but now since I am s-on, I am not able to flash anything and no (HowTos)
