Lost root w/ update help

[xdarkxheartx]

I was rooted on RAZR xt912. Phone updated to 6.12.181 and I lost root. I deleted bloat ware and I have the sbf files to get them back in order to reboot and use Rootkeeper. The question I have is which sbf do I use. 6.12.181 or do I use 6.12.178. Or am I off completely

Maybe I should mention I'm trying to revert back to stock.

Just run motofail rooting Script. I know a few people has used it without a problem on .181

This. I used motofail to root .181 without going back to .173
