We have ordered similar device and it will arrive to our office in coming days. So it will be possible to make some tests.
Hold this Vivo V15 for some time, if you can.

Gsmserver · 10-26-2021, 15:38

Also we need some time for investigation.

Gsmserver · 10-28-2021, 08:16

At the moment, we have made a test with the device based on MT6771 (bypass authorization, service options) and everything went successfully. We expect that a fully working phone should pass the service operations without any problems.
What is the history of your V15? Is there a possibility of hardware problems? Is it possible to re-flash your phone and then repeat the imei repair with Sigma?
