Help! Wifi and sim card not working after messing around with custom roms

[sner.page]

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?

No output, I have checked in settings/status to see the IMEI numbers, but when I click on IMEI1 or IMEI2 shows "Unknown"

I don't know much about NVRAM, can it be fixed somehow or once I messed it up there is no chance to repair it?

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

Did you make a EFS backup in twrp? If yes, You can simply restore that backup and get your imei back

Well, I remember that I have checked all the boxes when I made the backup

Can I restore just the EFS backup made on PE with stock rom installed?

Yes, the EFS layout is the same regardless of the ROM.
