[Guide] downgrade from OTA 1.32.651.6

[Konfuzion]

Taken from XDA all credit goes to OP

This is only confirmed to work with 1.32.651.6.
Refer to toast's reply below to understand why it might not work with other versions.

1. I installed the latest RUU 1.32.651.6 found here:
here

2. And I was able to downgrade back to the original one found here:
here

3. Then did toast's root tutorial and got to the recovery and everything:
here

4. And am back to the rooted 1.32.651.1 with the ability to get to recovery and flash roms:

On step 2, the RUU was not able to reboot my device into the bootloader. So I booted into the bootloader myself (hold vol down + power on) then plug in the usb, select fastboot and then start the RUU from the PC. It installed like a champ and brought me back to 1.32.651.1.

Hope this helps everyone who decided to upgrade.
