Perma-root confirmed on Desire Z and G2!

うちのZは昨日到着し一日黒SIM入れて使ってましたが、なかなか良いタイミングでPerma-rootが取れたみたいです。もう遅いので今日はメモだけ残して、また明日作業しよう。。。

This pushes the 2 files to your phone using adb (the 2 files go in the tools folder and the wpthis file is for whatever your phone needs, ie. pre ota or post ota)
Code:

adb push hboot-eng.img /data/local/hboot-eng.img
adb push wpthis-OTA.ko /data/local/wpthis-OTA.ko

Then I ran these commands
Code:

adb shell
su
insmod /data/local/wpthis-OTA.ko

Returns this error: init_module 'wpthis-OTA.ko' failed (Function not implemented)
Code:

dd if=/data/local/hboot-eng.img of=/dev/block/mmcblk0p18

Run visionary again to lock root (it will say already rooted)
Code:

sync

Wait 2 minutes then reboot
Then run VISIONary again, and reboot

Finished =D
