Which is the most current modem?
-msm8974a-aaaanazm
-LGD801_20A_RADIO
-LGD801V_11b_RADIO

I've researched this for the past couple of hours.

Thanks in advance.

Hey! I've tried using both and to the best of my knowledge and experience, the 20A modem is the one and only. Be sure - depending which ROM you flash, especially AOSP - that you check your APN Settings once booted into the Android OS. Be certain you're on the proper T-Mobile US LTE settings for your area (usually the Global LTE settings apply) or you'll experience long data transfer rates and even problems downloading/updating apps from Play.

Cheers!

I've had reports of seriously muffled call quality...would this modem fix it do you think? Read that it may. I'm on Resurrection Remix 5.0.3 + Blackbird D801

Baseband / Radio T-Mobile

Is there any difference between the Cloudy KK Baseband for D801 T-Mobile (KK_Baseband_D801.zip) and this official T-Mobile radio (LGD801_20A_RADIO.zip) ?

I've been getting some static/echo during calls sometimes, and fewer signal bars, and was thinking maybe flashing to the official radio could fix it. Is there any danger of breaking the ROM or bricking the phone by flashing this stock T-Mobile modem, and am I correct in thinking it could potentially give me better reception?

Any help would be appreciated, thanks!

    I pulled the radio out of the Stock ROM that @SmiLey497 posted and dropped it into the flashable zip that @autoprime posted in the General Development thread. Thanks to both of them for their work.

    NOTE: THIS WILL BREAK ROTATION IF YOU ARE NOT ON THE STOCK 4.4.2 ROM.

    Is this compatible with 4.2.2 flex, I know I asked earlier but their more people on this forum now

    Custom G2 D801

    Another user reported that it works on Rayglobe which is another 4.2.2 ROM, as I understand it. You could flash it yourself and find out.

    Correct me if I'm wrong, but once you flash this. You don't have to again even after installing a new ROM? Or flash this every time you flash a new ROM?

    Correct, you should not need to flash this again. Unless you use the LG Support Tool to return to 4.2.2 stock (which contains the older radio) or if you flash an different radio, you should be good.

    Does anyone have the download for the stock radio for T-Mobile d801, I flashed this one but now my auto rotation doesn't work I'm n United states

    Does there happen to be any new developments on this radio so that it can be flashed without breaking rotation?
