Check my sig first, then these for proper and additional information:
[GUIDE] Possible FIX for the infamous eMMC problem..
[Q] Bricked my phone?
NOTE:
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 I also suggest to give THANKS to those who originally made/uploaded the files.
Requirements:
Common Sense
- it helps A LOT
HTC Sync for Desire S - Installed
- for its drivers and such, or you may just install the "naked" drivers
Android Windows Tools - Installed
- for adb, fastboot commands
HTC-Dev unlocked
- to change recovery and ROM
Custom recovery
- to flash Root Access
SuperSU or SuperUser flashable zip
- to have Root Access
Root Access
- to change phone version
misc_version file (attached)
- file needed to change phone version
GoldCard
- to flash any version of RUUs
RUU executable file
- to DOWN/UPgrade
Quick tip:
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.
Preparations
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.
Flashing Custom Recovery
a. The phone must be on bootloader, then go to fastboot
b. Open up command prompt then type:
Code:fastboot flash recovery C:\downsaga\recovery.img fastboot reboot-bootloader
d. Access recovery
Flashing Root Access
Modifying the version of your phone
a. Connect the phone using USB cable using "Charge ONLY" and USB Debugging is ON.
b. Open command prompt and input these codes:
Code:adb push C:\downsaga\misc_version /data/local/tmp adb shell chmod 777 /data/local/tmp/misc_version adb shell su cd /data/local/tmp ./misc_version -s 1.27.405.6 exit adb reboot-bootloader
c. Your phone should now be read as the version you've placed there (but not visible to settings)
Locking the bootloader
a. You should be on fastboot
c. In cmd use this command to lock the bootloader:
Code:fastboot oem lock
c. You might receive an error message on your CMD but don't mind it. The phone should restart itself automatically on bootloader, and you should be able to notice at the top saying "***RE-LOCKED***", and might also has *Security Warning*. Just ignore.
Downgrading
a. Make sure you are still on fastboot with the above message.
b. Open the RUU that you've chosen to install on your phone
c. The RUU must detect your phone version as 1.27.405.6
d. If you have received errors, then you've done something wrong. Review everything that you've done and check the guide again.
If everything went well, you should have successfully downgraded your phone and your HBOOT.
