UMIDIGI A7-A11, BISON and Power 5: Repair IMEIs, MEID and Google certificate

Krieger · Post time 2022-5-4 11:03:04

I reinstalled the ROM and the signal came back but it took a few minutes. Since 2021, with the last updates of that year, I don't see 4G, only 3G. I even thought it was a network problem, but everywhere I go I never get 4G and I saw that many have this problem.
So I'm wondering if it would be good to flash the MD1_DB (MDDB_InfoCustomAppSrcP_xxx) and AP_DB (APDB_xxx) files from some ROM that doesn't have a problem. Can anyone confirm, or have a method to fix it?

Umidigi Bison 2020 error, help

Thanks!
Where did you get the file?
I searched for the A7 Pro on Google and nothing, so I decided to use this file from the A9 Pro, as it has the same modem. But where there was an error signal, I unchecked it and started recording. When turning on the A7 Pro and soon the signal returned.
I don't know if I made a mistake, but I needed the device working for days.
But it's still only on 3G, I don't know if it's the operator's problem, but I got LTE anywhere, now it doesn't get nowhere since the antepenultimate update
