OnePlus 8 Pro IN2025 no sim cards detected. Help! - OnePlus 8 Pro Questions & Answers

Hey y'all
I just got a used Oneplus 8 Pro IN2025 and everything works except the dual sim cards are not detected. It shows both sim card slots have a IMEI number on Android 11. Anybody have a solution to this issue please help me. Maybe a partial corrupted EFS partition.
Thank you

So you want all the contacts to be on your sim card?
I kitkat you can go to contacts - settings - import/export contacts and choose what you want to do
there isnt any option to export contacts to sim

As I know it there is NO SIM exporting in AOSP, only in stock, you can export to your SD-CARD easily.

After flashing Cosmic CM 5.4 you have to flash another kernel
Full screen caller Id not enable by defailt. You can change this by yourself.
Screenrecord not working
Camera fc sometimes when you exit it, but that is with more CM builds when you leave the camera app
This are the ones I noticed so far

I tried it with an old sim and old SD card, checked they were recognised beforehand but only sim one was found the SD and 2nd Sim seem not to be found
I think the kernel read the SD and just shut off the second antenna.
(I'm not sure but yea.)
Have fun modding!

fingerprint sensor not working

So, I had cyanogenmod installed and then I forgot to delete my fingerprints before I installed the stock rom. Then I completely formated my phone so I didn`t even have an os and then I installed nougat revolution mod on my phone. When I tested the fingerprint it almost never works.
You messed a lot the phone :/
You should rollback to stock MM firstly.

i think you can't remove fingerprints through twrp, they're stored somewhere else

i don't know exactly, but i think the only way to remove them is by installing the stock rom and then remove them

they should be there, otherwise try factory reset from stock rom, and confirm there are no fingerprints stored, and then install cm13 again.
