[HOW TO]return to stock (gingerbread) from revolutionary or normal hboot(11/2/11)
i have removed the dead multiupload links that have for some reason been causing an extreme amount of confusion. i thot the "mirror" following each link was self explanitory,but apparently not.
from this point forward,i will no longer respond to "links are dead" posts or PMs if i check them and find them to be working.
in other words,yes,the links are working.
the return to stock thread from 5/17 is outdated. it still works,but afterward youll need to allow your phone to OTA to mr2 if you want to be on the current firmware.
between the newer firmware,and having to execute extra steps if rotoed with revolutionary,the old thread seems to be causing some confusuion. i thot maybe it would help if i threw it up here as well
its geared toward a revolutionary rooter who doesnt have adb set up,so sorry if its a little insulting to more advanced users
last and not least,if you rooted old skool,and just need to flash mr2 files,just skip the part detailing getting the old 1.04.2000 eng hboot back. go directly to: Putting current stock firmware and s-on back onto the phone
as soon as the GB OTA hits for real(
) i will update this with those files.
*please read all directions first. post up any questions you have before doing anythingyou are messing with your bootloader,wich is a vital part of your phones operation. screwing it up WILL make your phone an expensive paperweight.
how to unroot
the revolutionary method of rooting uses a sneeky hboot exploit,and replaces your stock 1.04.0000 or 1.05.0000 bootloader with a modified permanent hboot. it not only gives you all the same fashboot flash abilities as the original engineering bootloader,but it very effectively blocks other hboots for overwriting it. its good,as you will remain s-off if you accidentally flash a full RUU,or accept an OTA,but makes it a little trickier to remove.
for the time being, removal requires ADB to be set up and running and some commands entered in "fastboot" to to allow the permanent hboot to be overwritten. once an "s-on" tool is release,ill take th is part of this guide down.
if you rooted the old skool manual way and have adb setup and working,you can use this guide
to remove the permanent hboot.
with Revolutionary,will come a new wave of rooters that have no clue what adb,or fastboot even are. for you folks, Sele and the crew in the "rescue sguad" at HTC Thunderbolt Forum
have come up with a really clever way to get the adb basics,and the eng bootloader to flash,with minimal setup and confusion. with their permission,im borrowing it for our guide here.
*WARNING* no siginture or file checks will be done flashing the new bootloader in hboot or fastboot.fastboot will literally flash "lets golf" as a bootloader if you tell it to. DO NOT mess with your hboot unless absolutely neccessary to return to stock for warranty purposes.
if youre just tired of being rooted,flash the gingerbread ruu to get back to unrooted firmware and factory recovery. leaving the revolutionary s-off bootloader in place is the safest,and best option,and will not
affect your ability to recieve OTAs.
- if youre just following this procedure because youre tired of being rooted,skip this next section and leave the permanent hboot in place. jump to "Putting current stock firmware and s-on back onto the phone" and flash only the first "PG05IMG_no_hboot_2.11.605.9" file(you can flash the 2nd file too if you want,but the permanent hboot will block it
Setting up adb and removing the permanent hboot if youve never used adb before
1)if you no longer have the htc drivers that you installed when rooting with revolutionary,download them again from here
on revolutionarys website.
2)next download *link removed
)to somewhere convenient that youll be able to find it,like your desktop,or a "downloads" folder. it contains the old eng 1.40.2000 s-off hboot,and the bare minumum tools to install it.
3)the following directions were using windows 7 and chrome browser. other OS may be slightly different-the end result is you want un
folder to be on the root of your C: drive.
-find the tbolt.zip
-click on tbolt.zip
download and open it.
,there is a folder labled tbolt
. drag it to the root of C:. inside tbolt
is the unpermanent hboot and some adb tools.
4) charge your Thunderbolt to 100%
5)click on then "start" bubble in the lower left corner of your screen. type "command" in the search window and hit enter. this will open a small black command window.
6)enter the following command(by typing or copy/paste):
you should see your promt in the window change to: c:\tbolt>
7)enter the follwing command:
check the output on the command window. THIS IS VERY IMPORTANT
. the command must equal exactly 6991368ee2deaf182048a3ed9d3c0fcb
if it does not,STOP!
. delete the tbolt.zip download,and the unzipped tbolt folder from C:,re download and try it again. again,do not procede if the output in your command number does not equal it exactly.
8)once the number matches,you can continue. copy and paste the following codes into the command window:
the output should be your phones serial number
this will cause your phone to boot into FASTBOOT mode,wich is a white screen with colored letters.
the result again,should be your phones serial number.
9) now youre ready to enter the command to unlock the permanent hboot and flash the new,non permanent one.
write the new hboot:
if you select bootloader at this point from the fastboot menu, youll still see the permanent s-off hboot,so select reboot with the volume rocker and power button and let the phone reboot. after it boots,you can adb reboot bootloader again,or power off, then power on/vol down and check that your pink "UNLOCKED" or "REVOLUTIONARY" is gone and you have the old 1.49.2000 bootloader.
here is what you should see in the command window,the red are my inputs:

after getting the bootloader back to the original s-off,engineering 1.04.2000 hboot download these 2 files:
2) *link removed
rename PG05IMG_no_hboot_2.11.605.19.zip to "PG05IMG",move to your sd card,and flash in hboot.
this is important!
you must flash the PG05IMG_no_hboot_2.11.605.19.zip first
after successfully flashing that,you will be on unrooted gingerbread with an eng s-off bootloader. delete the PG05IMG file from your sd card. now place the PG05IMG_hboot_ONLY_2.11.605.19.zip on your sd card. check the md5. once youve verified it matches,you can rename PG05IMG and flash it.
flash the hboot file after
you have successfully flashed the rom.
now you are 100% stock on latest firmware. unrooted gingerbread 2.11.605.19 with *locked*
1.05.0000 s-on bootloader.
as always,be as cautious as possible doing hboot flashes
,and follow directions in the http://androidforums.com/thunderbolt...rminology.html
to flash these files if youre unfamiliar with hboot flashing.
start a new thread before attempting this if any part of this confuses you. without a bootloader your phone is a paperweight,so we want to help you prior
to making any mistakes
last and not least:
if you have non working hard buttons,or no screen,see the directions in this thread on AF
