1) In what order? Are reboots required between flashes of 4 different zips?
I nand first, boot into recovery, flashed, reboot to finish zip install, package installed after about 1-2 minutes, phone boots and I checked antenna's (with the exception to the 4G which I have to flash back to my stock rom)
2) You cannot nand back up any of those items. I'm not going to test without knowing first that I'm not going to brick my phone.
true, but he has conviently posted all radios just in case these give you a problem I just flashed them and have had no problems
3) No help here.
using CM6rc2KK#1 with clockwork 2.5.0.1
