How To Unlock Bootloader And Root HTC Thunderbolt 4G

I have some great news for you HTC Thunderbolt owners, because we will present the easiest way on how to fast root your device and also unlock it by using the boot loader. Let me tell you that you have to keep in mind that there are advantages as well as disadvantages if you root your smartphone.

Well, in this case, advantages are very useful, because users will gain access to the root folder ( which can’t be accessed with un rooted devices ), and downgrade the flash as you like. Disadvantages include no custom recovery or the custom kernels.

In other cases, if the device is flashed with beta firmwares could cause some application to stop working, and in the worst case you can simply ‘destroy’ the smartphone, and you won’t be able to put it back together. Or maybe you are some sort of expert.

So, before we start I have some important things to tell you. Keep in mind that all of your data will be lost such as SMS, contacts or other data saved on the smartphone. The best thing to do is to make a recovery to all your apps and personal data before you start.

Okay, now let’s get started so I can show you how easily you can root and unlock the HTC Thunderbolt via Boot Loader. First of all download this three files:

Please do not forget that you have to root the device by using adb and also be sure that:

  • adb shell chmod 777 /data/local/psneuter

  • adb shell chmod 777 /data/local/busybox

  • adb push busybox /data/local/

  • adb push psneuter /data/local/

The only thing you have to do now is to extract the su.zip and push the same to the root of the /sdcard:

  • adb push su /sdcard/su

Now extract the misc.zip to the sd card and then obtain the temporary root and flash the custom misc.img using the following command:

  • adb shell ( the shell should now display ‘$’ )

  • Run: /data/local/psneuter

After this process, it will exit out of adb, and adb will restart as root:

  • adb shell ( the shell should now display ‘#’ )

Now run: /data/local/busybox md5sum /sdcard/misc.img. Output should be c88dd947eb3b36eec90503a3525ae0de

Now write misc.img:

  • dd if=/sdcard/misc.img of=/dev/block/mmcblk0p17

  • exit

Right now your smartphone will boot into the boot loader and check the image. After flashing and the device reboots, write protection to /system has been disabled. Please repeat step 2 and get psnueter and busybox back on your smartphone. Now please delete PG05IMG.zip from the sdcard. After this turn on USB debugging and installing from other sources than the market.
