Well, I went into twrp to try and fix it, and ended up erasing things that shouldn't have been erased, i guess. So, now I'm just trying to get everything back to stock so I can start over. I figured doing the RUU would do that. But, I can't get the darn thing to install, both with the Windows program and using fastboot. And, I don't have S-off, but don't know how to do s-off from the fastboot menu. Any help would be greatly appreciated, as I've been trying to fix this now for two days. Thanks all.
I deleted your post in the s-off thread..
This is the correct thread for your question. No need to Double Post.
I'll be glad to help you..
What error are you getting trying to run this RUU ?
Have you tried following Scotty85's instructions here:
RUU: T-Mobile 1.27.531.11 - 7/23/13
