Hi good people,
My Vivo V7+ prompted an OTA system update 5 days, so i downloaded and installed the updates. Once the update is finish my phone version now is PD1708F_EX_A_3.10.2. But now my phone cannot detect SIM card even though i never touch my SIM.
So i spent many hours on reading and watching YouTube for solution, and i tried to flash back into stock rom firmware using QPST but it always give me "Sahara Fail" error. I got into EDL mode by shorting the test point at the back of the phone (which took me sometime to research how to get EDL mode).
I gave up flashing via QPST because of the "Sahara Fail" error. So i checked my phone and found out the two IMEI are missing, and i dont have the original box that has IMEI writtten on it. I don't what is the original IMEI.

Showing no SIM card and no IMEI.

So i thought maybe fixing IMEI will solve the no SIM card problem, but i don't have my original IMEI, i don't have the box when i first bought it.
I read a lot about UMT tool and MRT tool but i don't have any dongle. I know this is a challenging problem but I some expert developer will help me.
