READ THIS:
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. :rolleyes:

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the return to stock thread from 5/17 is outdated.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:)eek:) 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. :eek:

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.

*AGAIN- 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 (mirror)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 unzipped,inside tbolt folder to be on the root of your C: drive.
-find the tbolt.zipdownload
-click on tbolt.zip download and open it.
-inside tbolt.zip,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):
Code:
cd c:\tbolt
you should see your promt in the window change to: c:\tbolt>
7)enter the follwing command:
Code:
md5sums hbooteng.nb0
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:
Code:
adb devices
the output should be your phones serial number

now enter:
Code:
adb reboot bootloader
this will cause your phone to boot into FASTBOOT mode,wich is a white screen with colored letters.

now enter:
Code:
fastboot devices
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.
to unlock,enter:
Code:
fastboot oem mw 8d08ac54 1 31302E30
write the new hboot:
Code:
fastboot flash hboot hbooteng.nb0
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:

Putting current stock firmware and s-on back onto the phone

after getting the bootloader back to the original s-off,engineering 1.04.2000 hboot download these 2 files:
1) PG05IMG_no_hboot_2.11.605.19.zip
mirror: https://rapidshare.com/files/271867813/PG05IMG_no_hboot_2.11.605.19.zip
md5: 334909756073760b3d7316e51a4ce837
2) *link removedPG05IMG_hboot_ONLY_2.11.605.19.zip
mirror:http://www.mediafire.com/?0z0rlzh9lrnh0qs
md5: d26b3253358407d459c654e6729a39ca

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.

again, only 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-all-things-root/353591-how-some-root-terminology.html to flash these files if youre unfamiliar with hboot flashing.

*please 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

Nice

Awesome Found that there is also another way you can use the same method from the original root instructions.

adb push yourhbootfilenamehere /data/local/

adb shell

dd if=/data/local/yourhbootfilenamehere of=/dev/block/mmcblk0p18

Then just put the stock image on your sd card and use

adb reboot bootloader

and flash your stock firmware

Hope this helps anyone looking for a slightly quicker way

Not sure if this is a problem but...

After I un-rooted last night and ran the 2.11.605.5 RUU, I now get a bright pink message at the bootloader saying *** LOCKED ***. Anyways, the device now states S-ON and I am running stock. Is the LOCKED message something to be concerned about?

no the locked message is just something new they put into it some people think it means they might put it in the list of officially unlockable devices soon check it out here htcdev.com/bootloader

while i dont know that youll save any time doing it this way, this is certainly anotehr way to skin the cat if you have adb set up,and are fairly savy at using it,as there are alot of small details youre leaving out.

also i need to add a couple of things:
1)you will need to reboot your phone between
Code:
dd if=/data/local/yourhbootfilenamehere of=/dev/block/mmcblk0p18
and
Code:
adb reboot bootloader
as,rebooting imediately to bootloader will take you back to the revolutionary one. the new hboot is written on reboot.

2)be extremely careful with this. if you choose to flash a stock hboot rather than the engineering one,you risk a security warning if you flash the wrong hboot overtop of the wrong custom firmware. youll then be stuck with an s-on hboot and only be able to run newer RUUs to try and fix it.

if you really want to use this method,the safest way would be to run the RUU first. youll have to get a temp root shell(zergRush prolly will work),then run the command to replace the hboot that matches the firmware that you flashed.

Is the LOCKED message something to be concerned about?
as was said,this is just the new hboot. it does contain htcdev unlocksupport. thos that doesnt neccessarily mean they will ever give us a key ;) not that it matters anyway,htcs "official unlock"only unlocks system,boot,and recovery,and is still an s-on hboot. better than nothing i guess,but since we have revolutionary and other root methods,theres no advantage to using the official unlock fomr htc.

just to be cleared to just go back to unrooted stock to receive future ota's is just follow this: will this take my s-off off..also can I reroot with revolutionary later..
the reason i want to go back to stock is the ota update notifications are getting annoying and persistent..

Putting current stock firmware and s-on back onto the phone

after getting the bootloader back to the original s-off,engineering 1.04.2000 hboot download these 2 files:
1)PG05IMG_2.11.605.5_no_hboot.zip
md5: b7ebb0b208f704c84f1224de16e61a8e
2)PG05IMG_2.11.605.5_hboot_ONLY
md5: e6df3ae14523508868dc811ecc5d4b07

rename PG05IMG_2.11.605.5_no_hboot.zip to "PG05IMG",move to your sd card,and flash in hboot.

this is important! you must flash the PG05IMG_2.11.605.5_no_hboot.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_2.11.605.5_hboot_ONLY on your sd card. check the md5. once youve verified it matches,you can rename PG05IMG and flash it.

again, only flash the hboot file after you have successfully flashed the rom.

now you are 100% stock on latest firmware. unrooted gingerbread 2.11.605.5 with *locked* 1.05.000 s-on bootloader.


as always,be as cautious as possible doing hboot flashes. again,please post any questions before doing anything

Did you root with revolutionary? If you currently have the 1.04.2000 Eng hboot,then yes. That will get you to stock unrooted gb. If you plan to re-root,there are stock,rooted roms you can flash in recovery,that will also stop the ota notices. :)

So is there anyway to accomplish this without being able to turn the phone on? Dropped my T-Bolt over the weekend, phone looks fine but the power button is now recessed. Tried popping it back out, etc. and no dice.

Tried setting up ADB, but it isn't recognizing my device. Not sure if USB Debugging was on before, but now I have no way of checking. Tried a few tricks I read online to get the phone to power on without the power button, but none have worked.

Thoughts?

id prolly not worry about it. if it wont power on,they wont know its rooted. i believe any hardware thats not working is fixed,then the phone is flashed with current firmware.

i do not believe they will fix the phone,then turn it on to try and catch you being rooted.

either way,since you dropped it,youre looking at an insurance claim anyway. and they could care less if its rooted or not ;)

Problems...

So i rooted with the Original root method I do believe and have had this phone for awhile, I followed the steps as stated but after I flash the H Boot and reboot to do the first PG05IMG I get No image, wrong image, so on and so forth... I have no idea what has happened, I even grabbed another Img file from Bliynd but it still does the same...

Never had a phone do this before, its like it see's the IMG but will not load/flash it... Any help would be awesome man, sry for the trouble...

Helpful info (?)

be careful! do not just blindly flash different images or RUUs. you need to use the files i listed,and make sure you flash them in the correct order.

if the PG05IMG is on the root of the sd card there are only 2 reasons its not found:
1)sd card not FAT32
2)incorrectly named

the phone must see "PG05IMG.zip" exactly. due to the way windows usually adds and hides file extension,its common to inadvertantely name to "PG05IMG.zip.zip" :eek: or in lesser cases just "PG05IMG". note that that is a zero,not a capital O

figure out which of those 2 is your prollem and your files will flash. :)

I know this is beyond dumb but since rooting with recovery anything I flashed was from cwr. How do I flash pg05img.zip from hboot? Will the phone then boot up allowing me to delete the file from file manager app or do I have to delete the first pg05img.zip from the computer?

Ok, so I originally rooted my phone using the ADB method. I used your stock RUU to unroot with S-off still off. My question is what is the easiest way to get root back with s-off already off and the original root bootloader?
