Are there any walk throughs for SFBing from .340. I just flashed to 2.3.32 and it did not wipe it, but simply moved the phone back to .320. I am now going to try the system only .340 sfb and see what happens after that. Is there a new process to all this now? Seemed a lot cleaner with .15
All you need to do to get from .320 to .340 is make sure you are on the right bootloader/kernel/baseband first. You can actually get the .340 system SBF file as a zip you can run from clockwork. It'll put you back to stock unrooted Froyo but with z4root it takes all of a minute to root, then just load up Apex or whatever you want to run and bam.
All the files are
here. Just make sure to follow the directions on that page including a full wipe before running the sbf file. This is the method I used to get to .340 OTA from the leak and it went flawlessly. To check what bootloader you have power down and then power back up with the camera and volume down button held to boot into the bootloader screen which will tell you what version you are on.
