I have searched forums and only found information about flashing SPF if running 2.1. I currently use the OTA 2.2 update verizon released then I rooted my phone. I am getting some errors and at some point want to go complete 100% stock again or if I mess up my phone due to a custom ROM. I was wondering how to do so. I searched forums but typing in " help with SPF" or "flashing SPF droidx" returns many results. If any one can help on how to do this. I have RSDlite and the stock SPF file already.
