Early this month, it was revealed to much outcry that the AT&T branded HTC One X had a locked bootloader. The manufacturer blames AT&T and stated that the handset has “restrictions” which prevent its bootloader from being unlockable. But a clever XDA member (grankin01) have found a solution for unlocking the bootloader on the American version of the HTC One X.
For those who want to unlock the bootloader on One X handset, you can head over to XDA post for full instructions. You think you can deal with HEX-editing skills and you know your way around ADB? Then all you need to is boot up ADB, copy and paste the appropriate commands, and simply execute the following instructions.
Alright, once again, you do this at your own risk!
You need ADB and an understanding of how to use it and have a rooted device (although I didn’t test this). You will also need a hex editor like HxD.
BACK UP YOUR DATA BEFORE DOING THIS!!!! WHEN HTCDEV UNLOCKS YOUR DEVICE YOU MUST START FROM SCRATCH!!!
1. Fire up your command prompt and go to the directory that you have ADB installed to. Type “adb shell” and hit enter.
2. Type “su” and hit enter. You now have root privileges.
3. Next type “dd if=/dev/block/mmcblk0p4 of=/sdcard/mmcblk0p4” and hit enter. This will dump the partition to your sdcard.
4. Next type “exit”, hit enter, type “exit”, and hit enter again. This should take you back to a command prompt for your computer.
5. type “adb pull /sdcard/mmcblk0p4” and hit enter.
6. Open the file (mmcblk0p4) with your hex editor.
7. Look for offset 00000210 and you should see CWS_001 with your IMEI number attached to it.
8. Change CWS_001 to ROGER001 and save the file as mmcblk0p4MOD.
9. Now go back to your command prompt and type “adb push mmcblk0p4MOD /sdcard/mmcblk0p4MOD” and hit enter.
10. Type “adb shell” and hit enter then type “su” and hit enter again. This will put you back into the android shell and give you root privileges.
11. Type “dd if=/sdcard/mmcblk0p4MOD of=/dev/block/mmcblk0p4” and hit enter. To test if it worked restart the phone into fastboot (type “adb reboot bootloader” and hit enter) and once the bootloader screen comes up type “fastboot oem readcid” and hit enter. It should read “ROGER001”.
12. Next type “fastboot oem get_identifier_token” and hit enter. Leave that up on your screen and go to HTCdev.com. Follow the instructions from there.
WARNING: We strongly suggests customers stay away from unlocking the bootloader. You need to keep in mind that this process will erase entire data on your handset. So, don’t forget to backup your personal data. Flashing custom ROMs is always not recommendable.
