Sele RS Team Leader UNROOT Safety OFF [RS Guide] How Return to Stock from Revolutionary Root These are unrooting instructions for those of you who rooted your phones via the Revolutionary method of rooting. One of the unique things about the Revolutionary rooting method is that it installs a protected S-OFF bootloader. This is a good thing in many respects because it prevents the loss of root when flashing RUUs or updating. However, it also adds an additional layer of complexity to unrooting your phone. The below process is going to take you through three steps. The first will be to download and install the files needed to flash a unprotected bootloader. The next step will actually flash this unprotected bootloader. And the final step will be exactly the same as the older unroot method. Credits: shadowmite, scotty85, jcase Part I - Setting up the files on your computer If you rooted your phone on the same computer, you should already have the HTC Drivers installed. If not, then re-download them from the Revolutionary website. NOTE: Make sure you don't have any PG05IMG.ZIP files on your SD card. If so, rename or remove them. The first thing you need to do is download THIS file. When prompted choose save and choose your desktop as the location to save the file. When download is complete, double click “tbolt” to open file. The next window that opens will show the contents of the zip file. At the top of the window you should see an option to “Extract all files” click this. The next window will show the path to extract to, it should read something like “C:UsersYour user nameDesktoptbolt” click Extract to extract the files to your desktop. You should now have a folder on your desktop labeled tbolt. Click on your start button and select Computer in the right hand window pane. This should open a window showing all of your disks on your computer. Now drag the “tbolt” folder (the one without the zipper) and drop it on your drive C: This will move the folder to the root directory of your hard drive. You may now delete (drag to the trashcan) the tbolt folder with the zipper. Part II - Flashing the Unprotected Bootloader (read carefully) This stage involves a small risk of bricking your phone. Please ensure you follow these steps exactly. ALWAYS START WITH A FULL BATTERY. Go to your windows button, type COMMAND in the search box. In the Command Prompt window that opens Copy/Paste the following commands: DO NOT copy/paste the part that says <press enter>, this is just so that you know it's a new line. Code: cd c:tbolt <press enter>md5sums hbooteng.nb0 <press enter> **IMPORTANT** The following checksum MUST display in the command prompt window. If it does not DO NOT PROCEED. Instead, redownload the files needed for your computer in Step I. 6991368ee2deaf182048a3ed9d3c0fcb If that MD5 matches, go ahead and Copy/Paste the following in the command prompt window: Code: adb devices <press enter> You should should get a response that says List of devices attached. Make sure the next line has a serial number with device listed after that. If you don’t see your device attached then something is wrong and you should not proceed. Code: adb reboot bootloader <press enter> Your phone will reboot into HBOOT. Do not power off your phone and type the following steps in the command prompt: Code: fastboot devices <press enter> You should should get a response that says List of devices attached. Make sure the next line has a serial number with device listed after that. If you don’t see your device attached then something is wrong and you should not proceed. Code: fastboot oem mw 8d08ac54 1 31302E30 <press enter>fastboot flash hboot hbooteng.nb0 <press enter> You should see a response that says sending OKAY and then writing OKAY. If it doesn't write correctly, DO NOT TURN YOUR PHONE OFF, download an IRC client and seek help at #thunderbolt on irc.andirc.net If it does flash correctly, use the volume rocker to select reboot and then proceed to the next step. Part III - Unrooting your phone back to stock Your phone is still rooted, however, now you have an unprotected S-OFF bootloader installed on your phone and you can now unroot by flashing two PG05IMG.zip files through HBOOT to return to stock.

Non root users wanting to return to 1.12.605.6 (Stock, pre OTA) can continue below: NOT FOR ROOT USERS Taken from AndroidPolice: [Tutorial] How To "Un-Root" The HTC ThunderBolt And Return It To Stock. Please check the site out. One of the most popular questions about rooting the ThunderBolt is how to undo the process and return to stock, which renews your eligibility for customer support. Well, here you go: Instructions: Please read the whole tutorial first, and pay attention to every detail. Note that your battery needs to be charged to at least 40% at the beginning of the process, and remember to check the MD5 sums of all downloaded files before diving in. As always, neither Android Police nor Team AndIRC are responsible for any damage this may cause to your phone, and, needless to say, returning to stock means you will no longer be able to use root apps like ShootMe and Titanium Backup. First, download the following files: Stock firmware (MD5 sum: 7141f5620f6128af77d50587e341f4b0) exploits.zip (MD5 sum: 3b359efd76aac456ba7fb0d6972de3af) Next, push exploits.zip and misc.img. Code: adb push misc.img /data/local/ adb push busybox /data/local/ adb shell chmod 777 /data/local/busybox To gain root and flash misc.img: Code: adb shell su /data/local/busybox md5sum /data/local/misc.img If the output is anything other than "c88dd947eb3b36eec90503a3525ae0de," stop and start over again. Now let’s write misc.img: Code: dd if=/data/local/misc.img of=/dev/block/mmcblk0p17 Rename "PG05IMG_Mecha_VERIZON_WWE_1.12.605.6_Radio_1. 16.0 0.0223r_NV_8k_1.41_9k_1.64_ release_174685_signed.zip" to "PG05IMG.zip" before placing it on your SD card. Finally, reboot into bootloader mode by entering the following command. Allow the stock firmware to flash. Code: adb reboot bootloader You’re done – your phone should now be stock, S-ON. __________________ I would like to Thank jcase for allowing us to post this information here for our members.
