Do they make a flashable modem or baseband updates for the V20? On my galaxy s4 you could flash newer modems and it would help with poor cell signal. Just curious if this is possible with the V20 (I have a dirty Santa unlocked H910a running a us996 bootloader)

From what I have heard, the modems are tied to the bootloaders on 10p and later, and they require the most current ROM to avoid ARB issues. I have the 10j or 10k modem and it seems to be running fine with AOSP. Nobody seems to have flashed AOSP over the 10p/10q firmware which is understandable due to the fear of it not working and being stuck on that firmware.

I flashed AOKP on my H910a unlocked by dirty Santa but had to switch to Weta because it kept randomly giving me a blue death screen. But that "may" have been due to me adjusting the kernel processor speeds with the Device control app. Not 100% sure though..

I've made a 10h flashable modem for my us996 but it doesn't seem to update. This is the correct command right?

package_extract_file("modem.img", "/dev/block/bootdevice/by-name/modem");

Can anyone post a screenshot of the 10h us996 baseband info or at least a date on it?

I have an arb0 h918. Will this work on that? Does it update the baseband too? My current baseband version is M8996FAAAANAZM-1.77008.1.80277.1

H918 stuff is setup so that if you cross flash firmware you brick (Other models can't cross flash H918 firmware either). H918 can ONLY run H918 firmware.

I played around with roms and lost all modem connectivity - phone thought it was in airplane mode when it wasnt.
Flashed the modem above and now voice and text work, but data only 3g no lte.
Any suggestions?
