Flash desired zip from recovery. Hope you made a nandroid backup.
vision_wipe_efs repackaged with permission from guhl source and license can be found in the zip files.
Sometimes using the built in format options in CWM dont work. The motivation behind creating the tool was that i was having serious bootlooping issues that couldnt be solved from flashing/formatting/etc from recovery. No matter what i did i would boot up and be greeted with a hundred force close messages and a hard reboot. it sucked. flashed the superwipe, restored my backup and was up and running in no time. This uses recoveries built in format command as well as the erase_image binary to complete destroy the partitions, reformat them and check the filesystems afterward. a log is then saved to /sdcard/superwipe.log
If anything, this is a great one click wipe tool for a complete wipe between roms, or to troubleshoot.
vision_wipe_efs wipes the mmcblk0p13 and mmcblk0p14 partitions and has been shown to fix the broken GPS for almost all users experiencing gps loss. the binary is to ensure no errors while typing dd commands which can cause device death. vision_wipe_efs was written and compiled by xda member guhl.
All three zips are safe and working.
YES ohsaka/ezterry released a superwipe for the g1, YES this zip is basically doing the same thing.
I didnt use any of ohsaka's superwipe.sh code, nor did use any binaries from his superwipe. Instead i use the built in erase_image and e2fsck that are already in CWM recovery. It isn't a rip-off, it is what it is, a superwipe tool for the g2. sue for me for using built in command in an open source environment and using a name with no copyright... idiots.
TROLLS: you're annoying, you contribute nothing. they have a name in biology for something that constantly feeds and never returns. Cancer. Please go back under your respective bridges unless you have something of value to offer.
