[GUIDE] Possible FIX for the infamous eMMC problem..
[Q] Bricked my phone?
RUUs with v1.xxx have HBOOTs with v0.98.000, while v2.xxx have HBOOTs with 2.00.002, and the ICS RUU has the only HBOOT v2.02.002
I will not supply the necessary files that is needed, you MUST know how to use SEARCH. I also suggest to give THANKS to those who originally made/uploaded the files.
- it helps A LOT
HTC Sync for Desire S - Installed

Android Windows Tools - Installed
- for adb, fastboot commands
- to change recovery and ROM

SuperSU or SuperUser flashable zip

misc_version file (attached)
- file needed to change phone version

Copy-Paste the cmd codes for you to not have any problem. 1 typo error (extra digit on misc_version) will render your phone unable to RUU.
a. Create a folder "downsaga" on your C:
b. Copy misc_version, recovery.img(custom) on that folder.
c. Copy SuperSU's or SuperUser's flashable zip to your SD card.
Creating a Gold Card (use below or attn1's GoldCard Method)
a. Install Goldcard Helper from the market on your phone
b. Run it and copy the CID for MMC2, or email the info to yours
c. This number has already been reversed so go to http://psas.revskills.de/?q=goldcard, fill out the required fields.
d. Download the image file that was emailed to you.
e. Connect phone as a "Disk drive" using USB cable.
f. Use Gold Card Tool to flash your image file to your phone's SD card. (you might need to reformat it first with Panasonic's SD Formatter)
g. Disconnect safely from the PC.
NOTE:Your sd card is now a GoldCard unless you reformat it again. You should now be able to RUU to any version you would like given that the bootloader is LOCKED.
Unlocking the bootloader
a. Go to htcdev.com/bootloader
b. Proceed and follow every step on the guide
c. You just need to install Android Windows Tools files for it. No need to download the SDK and JAVA.
d. Once done, boot on bootloader and you should be able to notice if its UNLOCKED.

Modifying the version of your phone

Locking the bootloader
