Alot of the guides floating around showing how to flash back to stock rom is incomplete ( missing a few steps ) and will result in boot loop most of the time. the correct procedure is :

Part 1 : Setting up Fastboot.

1. Make sure you have java installed, if not get it from here : java.com: Java + You and install it.

2. Download the Android SDK manager from here : Android SDK | Android Developers ( get the exe download )

3. Install SDK manager, then run the android SDK manager.

4. Once launched it will show you available updates, choose ONLY these two "Android SDK Platform Tools and Android SDK Tools" and update them.

5. After update is complete close the sdk manager and go to the SDK manager platform-tools folder, normal path is : ( C:\Program Files\Android\android-sdk\platform-tools )

6. Copy the following 3 files from this folder : "adb.exe" , "AdbWinApi.dll" and "fastboot.exe"

7. go to your c drive ( c:\ ) and make a new directory called "fastboottools"

8. copy the 3 files above into your fastboottools folder.

9. so now your should have a folder like this : "c:\Fastboottools" with the following 3 files in it "adb.exe" , "AdbWinApi.dll" and "fastboot.exe".

That is it, Fastboot tools is setup. Proceed to next guide.

Part 2 : Flashing guide.

1. download the ROM from here:
ruu_chacha_htc_asia_wwe_1.57.707.2_radio_47.23.35. 3033h_7.51.35.19_release_228383_signed.zip

or here ( mirror link ) : ruu_chacha_htc_asia_wwe_1.57.707.2_radio_47.23.35.3033h_7.51.35.19_release_228383_signed.zip

2. Extract and copy the system.img AND boot.img to the same directory as your fastboot tools "C:/fastboottools" ( make sure to copy both files )

3. Enter the fastboot mode on your phone by pressing volume down + power button after the device has been turned off.

4. Choose fastboot on the phone by pressing power button, and then connect your phone to your PC

5. Using fastboot tools, open the Command prompt and navigate to "C:\fastboottools" then run this command on cmd: "fastboot flash system system.img"

6. Dont reboot, Using fastboot tools, run this command on cmd: "fastboot flash boot boot.img"

( The two commands in step 5 and 6 are different, make sure to type each one correctly and to do them straight after each other )


7. Reboot phone. let it boot up, you will still get bootloop or error message.

8. Take out the battery.

9. Boot back into bootloader ( Volume down + power ).

10. Now choose recovery.

11. Phone should now reboot itself and bam, all should now work fine.

after trying EVERYTHING else, this is the method that worked for me, i tried to cover every step possible ( alot of the other guides skipped few steps and that is where i got problems ).

hope this helps.

( PLEASE BE AWARE : This will remove recovery and root. if you flash back to stock rom using this method you will have to root your phone again. It will still be unlocked, just recovery and root will be removed. to re add recovery and root check part 3 below. )

Part 3 : Add recovery and root access back after installing stock rom.

1. Download the following 2 files, you will need them :
PH06IMG.zip
su-2.3.6.1-ef-signed.zip

2. Extract PH06img.zip to your "c:\fastboottools" directory. it will add the "recovery.img" file to fastboot.

3. Copy the file su-2.3.6.1-ef-signed.zip to your phones SD card, dont change the name, keep it standard, just put it in the root directory of your SD card.

4. go to the settings on your phone "Settings -> Power -> and Uncheck Fast boot" ( This is important, make sure fastboot is unchecked.

5. Take out your battery, put battery back in and boot into bootloader ( hold down volumedown + power )

6. Choose fastboot on the phone by pressing power button, and then connect your phone to your PC

7. Go to the Fastboottools directory "c:\fastboottools", Hold CTRL+Shift and right click in that Folder and open Command Prompt.

8. type inside command prompt : "fastboot flash recovery recovery.img" and let it finnish, takes less than a minute.

9. reboot your phone, but reboot it back into bootloader ( hold down volumedown + power )

10. Now using volume keys choose "recovery" and press "enter" ( not power button, rather use enter button in recovery else you sometimes get a "hat like" picture on the screen )you should now see the recovery options.

11. find the "install zipd from sd card" option and press enter, then choose su-2.3.6.1-ef-signed.zip and confirm to flash it.

12. once flashed reboot the phone and you will now have recovery and root access back again.
Click to expand...

it is recommended you update superuser to newer version and also install busybox.

Now that you have recovery installed you can also flash custom roms again.

I STRONLGY recommend once you reach this step that you make a backup of your rom via the recovery menu, that way you dont have to go through all this pain again next time.

The End !!!
