I get an error right after it gets to 1%! I know I relocked this thing to get 3.16 on here. Whats going on now? Anybody try reverting back? Anything would be helpful.

All three must line up correctly.

1. If you are using code prior to 3.16 then you need either have the following SPLs:
>>>a. The ReLocker 1.06 SPL if running official carrier released code
>>>b. The unLocker (original) 1.20 if running custom built roms
2. If you are using 3.16+ code then you need either:
>>>a. The reLocker if upgrading to the unofficial carrier released rom
>>>b. the unLocker (new) 2.40 if running custom built roms

If returning to 2.17 Official Carrier Released Rom from a 3.16+ build:

**Make sure you have your MSID/MDN/EPST codes**

1. Download your carriers official released 2.17 ROM
2. >>>a. run the relocker (as you are running this, make sure you follow the on-screen directions fully -- read carefully!)
(don't worry about getting out of the bootloader - tri-color screen)
3. Install your carriers official released 2.17 ROM

That's it.
