I believe after NB4 there was NH7 then NK2. Check the firmware thread in the general section for details / links.

How did this work out for you? I want to do the same thing you said you where going to do.

My motivation is to install TWRP recovery which I can't do on the i337. I intend to activate it on Cricket (AT&T network). Is it still true that I should stick with firmware, ROMs, and modems designed for the M919? I don't care about AT&T or T-mobile apps so that's not an issue. Basically, I want the best data rates available. Any gotchas that I need to be aware of?

Robert417919,

I use my SGH-M919 on an AT&T network also. I use the OK3 modem firmware and it seems to work great here. Although I am in Alaska, so top speeds of LTE are only about 6 Mbps where I live. Usually I can only get about 3 Mbps due to the lack of coverage around here.

You can either update to the latest OH3 firmware on your phone, or if you have an old model, with the MDL bootloader, you could also use this guide by lordodin912:

Also, if you are looking for good roms, you can always check out SlimLP:

Hope that helps!

Glad to help, and no, unfortunately not.
