- Numbers between ( and ) means radio name in Android (if this number is the same, like 10E and 10F it doesn't mean its the same radio! Before flash double check .zip name! )

Reception (in the house) for one is great. Full speed LTE (relative of course, depending on your subscription), full bars reception, very happy with it :good:

Using the previous modem usually the speed was around 25Mbit max. Now let's see if there are also some battery improvements (better signal means less battery use) :cool:

It is not a kernel. This thread is about the radio/baseband.

I've updated OP with more modems and a note if its a leaked or official version.

    @Step-han

    Can you create a flashable ZIP of the new 21A modem?

    Thanks in advance ;) :)

    See OP.

    Added 20W and 21A. 21A works fine in the Netherlands, slightly more signal.

    @Step-han can you please make modem from 21C firmware?

    Sent from my LG-D855 using XDA Free mobile app

    Added 21C to OP.
