Point me to downgrade back to 2.17?

Need some quick help on how to downgrade from the beta rom back to 2.17. I downloaded 2.17 and tried to run, but it errored out after 1% and said I cannot use it.

If someone could point me in the right direction, I would appreciate it.

TIA

Having the same problem. Can't downgrade.
Getting this error:

Same error message here. I wonder if this might be an issue with the re-locker spl? Anyway, I extracted the .nbh file from the 2.17 upgrade .exe by using 7-zip and renamed it to TITAIMG.NBH. Copied that to the root of my microSD card then ran the bootloader by pressing power+camera buttons and poking the reset hole. It took quite a long time but eventually restored the 2.17 ROM. All I had to do after that was to restore my backup. I'll look forward to the eventual release ROM but this test version was simply too unstable for me.

you have to run the relocker from the sticky, then run the 2.17 upgrade

As soon as I posted this question the server went down. lol

I asked someone at XDA, and they pointed me to the locker.. I used that and then upgraded 2.17. It failed the first time, but the recovery walked me through fixing it. Then when I got everything back to normal, I found out my MSID was nuked... I didnt bother writing it down, so I had to call Sprint.
