[Xperia Arc Q&A, Help & Troubleshooting] kibaa12:
now recently my mate has been having some issues with his Arc S mainly due to him wanting to make his phone look so much like ICS he has jammed it full of every app to get the job done when i said i could flash Cyanogen and make it look prettyiful for him he said sure....now my problem

his phone was on .42 firmware so i Zerged the device to root it and also unlocked the bootoader(Not through sonys site)....im able to get into flash and fastboot modes now when i try to flash a boot.img file using flashtools or even just fastboot commands no matter what i try i continuesly keep getting Cannot flash Boot.img (Device needs to be Rooted)
