[Thunderbolt Android Development] scotty1223:
this thread is dedicated to the current known methods of rooting the thunderbolt.

i will do my best to change this post as these methods are modified or become outdated,and keep the best,current methods here.

if youre reading this and considering rooting your device,a word of warning:

DO NOT ever attempt to accept an OTA while rooted and running a custom recovery.

an official OTA update needs the stock recovery to apply it. attempting to take an OTA without the stock recovery can result in a failed harmless attempt,a fixable bootloop,or even a brick. so please... dont do it.

and now,on with the info. enjoy :)

Revolutionary

Revolutionary by unrevoked/alpharev does not wipe your data. this is 100% the best,and most reccomended way to root your thunderbolt at this time.

see this page for info:

Revolutionary

and a video from nate mills:

How to Root - HTC Thunderbolt (No Data Wipe! Newest & Fastest) - YouTube

special note:

the minor OTA to firmware number 2.11.605.9 patches the exploit used by revolutionary. there are 2 options:

1)several users have reported being able to downgrade to 2.11.605.5 simply by running an RUU for that firmware,despite an s-on hboot wich would normally prevent you from going backwards in version numbers.

(need verification downgrading still works)

*please note that downgrading WILL wipe your personal data

2) achieve temp root via another means,then run revolutionary(this method follows)

feel free to do wichever is most comfortable :)

how to root 2.11.605.9/2.11.605.19 WITHOUT downgrading

as usual,i take no credit- i just put it together :)

-jelly doughnut for pointing me to this thread,and the Desire HD guys for this thread.

*make sure you thank jelly in

this post

-sele and crew at HTC Thunderbolt Forum for what i like to call the "mini adb" concept

1)download miniadb_tbolt2.zip from here: mini-adb_tbolt2.zip

md5: ef01f616471673d3eeb71b4cac4b8118

2)set up adb:

-extract miniadb_tbolt2.zip and place the

unzipped folder

onto the root of your C\ drive on your PC

-open a command window. windows 7,click on start bubble,type "command" in the search box. a small black window should open up

3)download DHD Downgrade folder

4)open the DHDDowngrade.zip file,then the folder contained inside of it. transfer "Fre3vo" into the tbolt2 folder with adb/fastboot.(ignore the rest of the files in DHDDongrade,fre3vo is the only one you need)

5)in your command window: change to the tbolt2 directory by typing:

cd c:\mini-adb_tbolt2 (your promt should change to c:\mini-adb_tbolt2>)

*note that in the next few steps,anything in bold type is an adb command. you can directly copy from this window,and paste into your command window to eliminate typos.

6)enable usb debugging,plug in your phone via usb. select "charge only" mode.

7)make sure adb is seeing your phone:

adb devices (should return your serial number)

8) enter the commands from your link,one at a time,hit enter after each:

adb push fre3vo /data/local/tmp

adb shell chmod 777 /data/local/tmp/fre3vo

adb shell /data/local/tmp/fre3vo -debug -start F0000000 -end FFFFFFFF

9)make sure it worked. when you see "exploiting device" then your command prompt again:

adb shell (if your prompt changes to a # youre good to go)

10)run revolutionary again. this time it will work really fast. you can have it install clockwork if you wish to use that recovery.

10)flash the superuser 3.07 files linked on revolutionarys info page

youre done :D

heres what youll see in the command window(red are my inputs,blue are just additional comments):
