Devs , I will tell you my story ending with my problem ... So I was trying to upgrade my hboot using the misc editing method so the bootloader will check that the version is similar and won't deny the hboot update , so I edited it successfully and upgraded , unlocked , flashed roms etc ... but after a while , I noticed that I couldn't mount sd as disk drive while USB debugging is on ! neither i can use htc sync even when usb debugging is off , when i select htc sync it automatically turns on usb debugging and bricks the connection ! moreover , in recovery debugging is always on and non-toggle-able , so I can't mount my /sdcard as disk drive through recovery ... I tried reflashing the whole RUU from PC , didn't work , tried getting another misc.img from a working phone and same CID and flashed it , didn't work , tried flashing playing with hboot versions from 1.08.0099 to 1.09 to 08.0000 , not working ... any ideas guys ??
