How To Unlock Bootloader On The HTC Butterfly J?

We already mentioned our prevous post that how to install custom recovery and root HTC butterfly. But before installing recovery and root it need to unlock the bootloader. The HTC J is the Japanese version for KDDI network of the Butterfly, and is a pretty packed device with a 4.3-inch display, 1.5GHz dual-core CPU coupled with 1GB RAM, an 8MP camera and running Android 4.0.4 out of the box.

To begin the process you should have the battery life more then 75% .
You should have ADB and the necessary drivers installed before you can start.

Download htcj_butterfly_diaggetroot.zip [Download HERE

Follow Steps Below

1. Enable USB Debugging on our device. To do this, go to Settings > Developer Options and tick the Enable USB debugging checkbox.

2. Extract the htcj_butterfly_diaggetroot.zip file you downloaded above to your ADB folder [the folder where adb.exe is present].

3. Open a command prompt window in this folder. To do this (on Windows 8), hold Shift on your keyboard and right-click on the folder. Click on Open Command Window here.

4. Connect your device to your Windows 8 PC.

5. Type in the following commands

adb install diaggetroot.apk [Enter key]
adb push getroot /data/local/tmp/getroot [Enter key]
adb shell chmod 777 /data/local/tmp/getroot[Enter key]

6. On your phone, you should now find an app called BreakSuidDiag installed. Run this app and wait for the Hello World! message. [This will give you temporary root access]

7. Back on the PC, run the following commands:

adb shell [Enter key]
/dev/sh [Enter key]

8. You should now have the # symbol on your PC’s command screen and this signifies that you now have root access. If not, turn WiFi on/off on your device and run the /dev/sh command again.

9. Next, run the following commands:

echo -ne “11111111″ | dd of=/dev/block/mmcblk0p5 bs=1 seek=20 [Enter key] {Changes the CID to 11111111}

reboot bootloader [Enter key] {Boots your device into the bootloader}

fastboot oem readcid [Enter key] {Should now display the CID as 11111111}

10. Once you see the 11111111 on your PC, head to HTC Dev website.

11. Follow the instructions on the HTC website to complete the unlocking process [Remember to select ALL OTHER SUPPORTED MODELS when asked to choose!]

Your HTC J should now be unlocked, enabling you to root your device and install a custom recovery, and then a custom ROM of your choice!We already discussed in out earlier posts
