Hello!

Somehow I managed to break my wifi and sim card functionality on my oneplus 7 pro EU

I ve tried some custom roms like PixelExperience and crDroid and today I wanted to go back to stock Oxygen OS

I've used MSM tool and more than 5 versions of stock firmware and the "unbricking" process works fine, but I can't get the wifi and sim card to work

Can anyone help me with this? Maybe it's a deeper reflashing for modem or smth..

Quick update, I've tried to restore from a TWRP backup made with PixelExperience12, no success

I have tried reflashing with MSM tool the original rom EU, Global and China version, different versions of android - 9, 10, 11 - I give up

Since nobody seems to reply here, the only solution I've found is to make a service request on oneplus official website

If someone have the same problem and is searching for a solution, I will keep you updated

What output do you get when you dial *#06#? I think you messed up your NVRAM?

Looks like your imei and WiFi Mac adress got corrupted and erased and you can't do anything by yourself if you don't have a backup because these two things are unique to each device. You should flash stock ROM and contact one plus about your imei

I have my IMEI numbers on the original box but I don't know how this can help

I have some TWRP backup files.. but my foolish mistake was to make a backup with PixelExperience installed not the stock rom
