I am on Apex 2.0 RC2. (4.5.596 BP_C_01.09.07p ) . I would like to upgrade to the .13P baseband but not the entire .602 release. I understand that I will first need to SBF back to to a .340 based ROM. That's where I get foggy. Is it at that point that I should install the TBH "radio only file for 2nd-init ROMS? Then how do I get back to .596, so I can reflash to Apex 2.0 rc2? Some folks have suggested that I two part back. Why the two part? Can you tell I'm new at this? Hope I got all the verbs, numbers and initials right.
