I have an EA ROM on an ATT device, but we all faced on the A11 that after fixing the NT code, we are not able to use LTE and mobile data, but then we had the PDC tool where we loaded the .mbn.
Now on the A12 we don't have the ability to use PDC so I was forced to do something to get LTE & mobile data back and I made some changes to the modem .img where the problem was fixed.
Note: I read before that some people were not able to fix the fingerprint after croosflashing ROMs, now we can do it but by cross-modem images.
Current patched mods are for EA ROM A12 but there are one version for A11 if you do not want to use PDC tool.
We have three versions of the modems.
- V1 is with minimal changes only for EU bands (outside it wil work or not)
- V2 & V3 is with slightly bigger changes and can be used outsde EU,
in the previous modified versions, users had the problem that Netflix did not work on their A11, with V1.2 or Universal version where the mentioned problems have been fixed.
- V1.2 only for A11
- modem_Universal fully compatible with A10+ android but there are more changes than V3 modem
Note: it is always better to use a modem with fewer changes, this ensures that the updates are original and newer.
5G and VoLte working.
You can flash modems easily via Fastboot to A/B slots or you can flash via Qfill.
Flashing patched modem won"t bricked /bootlop your device.
