Hello, I need you help !

I have a UMIDIGI Z Pro phone and live in France.

After a successful SN Writer process still not getting the working IMEI numbers is something that has never happened. Maybe the partition structure of your phone got damaged somehow. I suggest you to flash the latest stock ROM in Format All + Download mode, then use the SN Writer Tool again.

FW flash with SP flash tools did the job. I got my sim card workng again. Since I lost everything on my phone, I decided to try again and find what exactly caused this imei lost...
I reproduced exactly the same behavior. No sim card detected / working after reboot.
If you have a Z Pro model and whant to reproduce this just type *#*#3646633#*#* Then select Telephony / Band Mode / SIM 1 and disabled all 850 Mhz freq...
Got the ok message telling me operation succeeded. At this step phone is still working and sim card also.
But just reboot the phone and surprise... no more sim card working, il you type *#06# you have no number at all for IMEI...

So I am not sur I lost my imei, but the result seems to be this this. SN Writer tool did not solve again the pb, I also got the PASS green message.

The only way to recover my phone was to re flash the phone again with SP flash tool.

So to conclude, Z PRO owners to not try to disable (uncheck) frequencies with *#*#3646633#*#* method...

Hello, I've just registered to say thank you. Not an UMI user, but this tutorial found through a Google search and applied successfully to another Mediatek phone is the best I've found by far.
Again, thank you.
