[G2 General] l33t p1mp:
I just did this and I'm getting a bootloop on the T-Mobile 4G LTE white screen. Any tips?

I also tried this:

Press "Clear phone software update Registry"

After this leave Different Country instead Korea and select your language of your stock rom.

The Ok to proceed

Didn't work either.

Here's a log.
