Thanks. I think I should be good now. I'm just hoping there isn't something I'm forgetting or don't know about. I'm always paranoid when I send a phone in. I posted the following in the link you sent me.
I'm sending my device in for warranty repair, so I'm going back to the stock ROM from NAND flashed Android.
I downloaded the US T-Mobile ROM from their site, extracted and renamed the RUU_signed.nbh to leoimg.nbh, put that file on the card, and reset while holding the volume down button.
Now I'm stuck on the tricolor screen that reads:
SPL-2.08.HSPL 8G XE
I'm stuck on this screen, and afraid to try to do anything else out of fear of bricking my phone.
What should I do next?
EDIT: Found out what I was doing wrong. I was holding the volume down button too long, so it was skipping the boot loader. Pressing shorter got me into the menu, and I was able to reflash with no problem.
I can't believe it's this easy!
My only question is, did this change everything back to when it was shipped to me? I have the T-Mobile WM USA ROM running now. This changed back my SPL too, right? Also, do I need to change the radio, or did the stock ROM take care of that for me too? I don't want to hear that I voided the warranty over some little thing I forgot to do.
