I'm on Vortex 2.0 for. 602 now. Can I make a backup wipe and flash cm with no problems or is sbf in order first? Also if I have cm can I flash back to vortex without sbfing?
You should be able to just wipe and flash. I have been jumping around on .602 ROMs successfully. I would be ready to SBF just in case because you never know but as I said it has worked for me no problem.
