INTRODUCTION:

This process will allow you to unlock Nand protection on all partitions at all times via Engineering SPL. Without going into details and driving more confusion, lets get started.

FILES NEEDED:

- PC36IMG.zip
- mtd-eng.zip
- flash_image.zip
- recovery.img

STEP 1~NANDROID BACKUP:

- go into the recovery provided in the PART 1 root method and do a nandroid backup before u begin this. we will use this nandroid at the end of this tutorial to get u back where u were.

STEP 2~FLASHING MTD PARTITION TO ENABLE DOWNGRADE:

- down;oad all files posted above
- unzip the flash_image.zip and the mtd-eng.zip
- put the flash_image and mtd-eng.img on the root of your sdcard
- go into shell on ur pc and do:
Code:

adb shell
cat /sdcard/flash_image > /data/flash_image
chmod 755 /data/flash_image
/data/flash_image misc /sdcard/mtd-eng.img

- this should only take a second or two
- now put the PC36IMG.zip on the root of your sdcard
- power off the phone

STEP 3~FLASHING ENG BUILD:

- hold volume down + power to boot into hboot
- it should now find and verify the PC36IMG.zip on the root of your sdcard. itll show a blue status bar on the top right of the screen.
- after a minute or so it will ask u if u wanna flash SAY YES
- affter it flashes the PC36IMG.zip it will ask if you wanna reboot. SAY YES
- once booted into Android put the recovery.img linked above on the root of you sdcard
- on your PC open a shell again and do:
Code:

adb shell
cat /sdcard/flash_image > /data/flash_image
chmod 755 /data/flash_image
/data/flash_image recovery /sdcard/recovery.img
reboot recovery

- you should now be in recovery mode
- do a wipe of data and dalvik cache
- navigate to nandroid restore and restore the previous rom setup
- come here to the forum, get and flash the latest radio
- enjoy... you can now reboot into recovery, write to system and other partitions while in Android. Also you now have a Engineering SPL so you can fastboot and much more.
