Please be extremely careful when doing this and follow any instructions for the process. I would also advise to read over the forum linked before going through it to make sure there are no known issues. Mods can we please sticky this thread? Easyroot + S-Off - xda-developers This is my easy-rooter for the Thunderbolt. I do not personally have a thunderbolt but I have tested it and fixed as many problems as I could. As far as I'm aware this will only work with firmware versions lower than version 1.12.605.9. If adb does not see your device try installing the htc sync drivers. If it still does not register please post here. THIS IS A WINDOWS-ONLY PROGRAM. You must have windows or a windows VM to use this. As always there is a small chance of bricking your phone. DISCLAIMER: AndIRC is not affiliated with this program and by using it you agree that neither AndIRc nor myself is responsible for any damages caused by this program. This provides all necessary files and gives you in-program instructions. Known bugs: In step 2 the program will occasionally display an error and inform you to contact someone on the AndIRC channel. If this is before the program displays your hash (which should be 6991368ee2deaf182048a3ed9d3c0fcb as stated) you should be fine. If it is after the hash and/or the hash is different click the step 2 button to start over. Do not restart your device. If you receive the error again then it is legitimate and needs to be corrected. Sometimes your device will not restart into the bootloader on its own. This is usually due to an adb error and redoing the step usually fixes it. This normally only occurs on step 1. Issues: The files take a long time to push. It could be anywhere from 3-10 minutes.

You can donate here, to the Japan Relief Fund, or any other worthy charity. my donation link is in my signature For those of you who are interested in how this method works, here's the explanation. I will be focusing on what the program does,not user interaction so much except where necessary. Push busybox, psneuter,and misc.img to /data/local/ Push PG05IMG_downgrade.zip to /sdcard and rename to PG05IMG.zip chmod psneuter and busybox execute psneuter check the md5 hash of misc.img flash misc.img to /dev/block/mmcblk0p17 if the hash is c88dd947eb3b36eec90503a3525ae0de reboot into the bootloader press power to enter bootloader and flash PG05IMG.zip (done by user) once back in android: remove PG05IMG.zip push busybox, psneuter, and wpthis to /data/local chmod all 3 files run psneuter run wpthis push the engineering hboot(hbooteng.nb0) to /data/local/ check the md5 of the hboot file (it should be 6991368ee2deaf182048a3ed9d3c0fcb) if it is flash hbooteng.nb0 to /dev/block/mmcblk0p18 push the PG05IMG.zip file to /sdcard reboot into the bootloader again press power and flash PG05IMG.zip (done by user) push su, busybox, and psneuter to /data/local chmod psneuter and busybox run psneuter mount /system as read/write (rw) copy su to /system/xbin/su chown and chmod su install superuser and RomManager I do recommend learning ADB as it is quite helpful but I realize that for some people that is a daunting task at first glance. I remember being a n00b and this will allow you to fully utilize your phone while still learning at your own pace on the side.
