I have the same problem, my friend

did you manage to solve friend?
I did all the procedure but the only thing that doesn't solve it is the calls that I can't call or receive, everything works except the calls, there is no other method to solve this problem please

Hello brother, I updated my umidigi bison 2020 with 6gb/120gb to android 11 and I lost my imeis but I managed to replace it with another one, the internet works, it receives messages but it does not work in calls, when I change to 3g or 2g it loses the signal, it only works in 4g, I did your procedure but the calls still don't work, do you have another solution friend, thanks.

Google Key (Certification/Certified Device) Issues!?  Here's why!!!

When starting the flashing process with "SN Writer Tool", it looks in the firmware folder for a "CERT" (google attestation key/certificate) file ending with a ".dat" extension (shown below).

1. [04 18 06:37:57][INFO]<__kpha_init>: KPH: Begin. 4210
   
2. [04 18 06:37:57][INFO]<__kpha_init>: Load Config from "C:\SNWriter_1924-4.2.1-up-1.2.1-vturkey_A9Pro128\tee_stuff\kph_in\kph_env.ini" OK.

4. [04 18 06:37:57][INFO]<__kpha_init>: META Version: 3
   
5. [04 18 06:37:57][INFO]<get_cert_name>: certname: UMIDIGI_A9 Pro_mt6771.dat
   
6. [04 18 06:37:57][WARN]<local_read>: fopen(C:\SNWriter_1924-4.2.1-up-1.2.1-vturkey_A9Pro128\tee_stuff\kph_in\UMIDIGI_A9 Pro_mt6771.dat) failed: No such file or directory
   
7. [04 18 06:37:57][WARN]<__kpha_init>: UMIDIGI_A9 Pro_mt6771.dat not exist, certname_len : 25

Copy the Code

In my case it is looking for "UMIDIGI_A9 Pro_mt6771.dat" which is nowhere to be found in the firmware I downloaded (UMIDIGI_A9_Pro_1_128GB_V1-0_20210617)...

Unless "UMIDIGI", or @bensebacsi, provides these files to us I am unaware of any method to PROPERLY correct this issue...

If anyone has anything to offer/add, please do!

In a distraction, during the flash of my A7 Pro, I ended up forgetting to select the correct one, which firmware upgrade and ended up formatting. I did the IMEI recovery procedure and everything went well, but the mobile network signal did not activate as soon as it restarted, it took a while. Then it was active until I need to restart due to some crashes, after completion there is no more signal.
I did the modem flashing procedure described here, but it didn't work. What can it be?

Krieger

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
