view story

http://forum.xda-developers.com – Hi I have HTC Desire S. After OTA Upgrade HBOOT 2.00.2000 . So revolutionary method did not work. Unlocked using HTCDev.com Used AndroidFlasher with CWM Recovery and rooted my device. Can i simply install another custom ROM? If no, How do i get S-OFF now? Or I will have to revert back to Stock ROM and root via another method now? Device details in my signature. (HowTos)
