[GUIDE] How to apply RUU to HTC unlocked bootloader devices

---

If you unlocked your device using HTC unlock method (www.htcdev.com), and accidentally bricked your device (like I did, my device hangs in the HTC logo screen during boot), last resort is to apply RUU to resurrect your device.

Requirement:
1. The device can still enter FASTBOOT
2. You have the corresponding RUU

Procedure:
1. Enter FASTBOOT, and then connect to your computer (FASTBOOT USB will be shown)
2. Open command prompt in your computer
3. Relock your device by typing "fastboot oem lock" (you should know what is this if you HTC-unlock your phone before), the device will reboot.
4. Enter FASTBOOT again (you will see *** RELOCKED ***)
5. Apply the RUU
6. You device will be stocked

Note: The device must be relocked in order to apply the RUU.

You can only use the 2.08 RUU. No earlier RUU's will flash. HTC built in Hboot version checks(among other checks) so if the Hboot in the RUU you are trying to flash is older than the 1.50 bootloader it will not flash.

If you are using the 2.08 RUU you have to relock before the RUU will flash.

My HBOOT is 1.49.0012 and it worked flawlessly. 1.50 doesn't reach Asia yet...

No one in this section will have the Hboot 1.49.0012. That's the GSM version. The CDMA version shipped with 3 different hboots. 1.40, (one before 1.40) and now 1.50
