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

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

Hey everybody I hope someone can help me to rescue my phone.
I flashed carbon and ukm. Then wanted to change GPU governor to simpleondemand and got hot reboots. Was not able to fully boot and lost imei. I tried to restore my backup but they didn't want to boot either, same with another fresh install. Thereafter I deleted synapse folder through recovery and was able to boot my restored ROM. Now I have no imei, no data, no WiFi... In addition my files don't show the files on my phone anymore I only can see them in my recovery, all is still there. My problem is I don't have an extra efs backup only two ROM backups. First I would have liked to know how I can rescue my data? Cause its not showing on booted phone and because of that also not on computer via USB. Is there a proper way to save and what can I do to maybe save my phone. I flashed ROM for years on many different devices and something like that never happened before any help appreciated thanks!!!

You can use TWRP to drag and drop files as MTP is a feature in TWRP now.

I firstly flashed the coloros ROM then flashed back to cm11s and then followed the instructions of this brickloop thread you posted. That's the way I got my imei back and a fully working device. Hope this may help.

It may work but there is no guarantee at all. Another region's firmware will include another modem version (May affect your signal / reception) and in some cases the partition table is different from the one your phone actually use, which means you can get trouble if you want to flash your region's firmware later. In any case make a backup of the phone's "EFS" partition to be sure your IMEI will not get lost and the phone become unusable.

"EFS" is one of the phones partitions storing somje data. You still can backup it, but thats not very usefull as the partition already got screwed up. With IMEI 0 you should not get any carrier signal // reception.

so it means, backing up my efs doesn't do anything if ever i flash a different firmware and screwed up for restoring?

As long your phone is not usable for getting signal or accepting your simcard you will gain absolutely nothing my performing a EFS backup as there seems notghing on it that can be saved.

I'm really curious about it as your carrier will normally refuse establishing connections to simcard in a device with invalid IMEI but in that case backup your EFS.

Hi,
The link was ment for anyone willing to take a backup of their efs for you. Just to make it easier
I would do it, but i don't have a computer available before new year.
Ok thanks no problem, I did try installing another modem and messed around a bit what then happened was imei unknown and baseband unknown. I reinstalled stock and unikernel and everything came back. Im lost on what to do next
First things first, I'm sorry for opening another thread on this but I feel the other ones weren't headed exactly in the correct direction.
A little background:
I was trying to downgrade my XT1541 to Lollipop since 6.0 was really bad and I got frustrated and used
Code:
fastboot erase all
The result was I erased my IMEI and I haven't been able to connect to a network carrier since. The problem can be solved by re-writing my IMEI but that's the difficult part.
What I gathered so far is I can use QPST, backup QCN, go into HEX and change IMEI there, then restore the QCN back to my device. The problem is I can't locate the IMEI in my QCN since my IMEI is now simply 0.
So in all, could someone make a backup of THEIR QCN and send it to me? I would flash it to my XT1541, locate the IMEI (since now I would know what I'm looking for), then change it back to my own.
Does that sound like something that could work? Can anyone help?
UPDATE1: Noone sent me their QCN however I did try to restore the one I backup up (which still has an IMEI=0). QPST Software Download reports
Received an invalid command from the phone.

I tried using Qualcomm NV Tools (from EFS Professional), which reads all the information correctly, however when attempting to write the following appears

So getting another QCN won't help as it seems that I can't write the IMEI (qcn) back to the device...
There are only two possibilities of fixing this... a 50/50 chance that a full factory flash will restore it (don't know how, but it does sometimes). If that doesn't work, then you need to send it to Moto for repair.

Well, unfortunately that leaves option 2... or turn it into a media play and buy a new phone.
Funny how `fastboot erase all` causes such a pain for some and not others... but once your IMEI is gone, there isn't much you can do. Moto kinda screwed the pooch on that one.
Hello, did u try Xposed IMEI changer? Maybe that will be a native fix for this issue.

WON'T work. No img we get our hands on will ever fix efs. the efs partition is unique to every android phone. Know two efs is the same.
Ouch ! OnePlus support is your last hope.. I'm sure they can fix it. Don't forget to back your IMEI next time, & store it under your bed & on the cloud.

There are ways of getting it back but it's incredibly tricky with a risk that you'll totally brick the phone which cannot be restored and there is no guarantee that it would even work on this phone.
I AM NOT RESPONSIBLE FOR ANY DAMAGE YOU DO TO THE PHONE WHEN TRYING TO FIX YOUR IMEI AND YOU TAKE FULL RESPONSIBILITY FOR YOUR ACTIONS.
Try this first.
I found a way, you need to have "EFS PROFESSIONAL" its free! https://forum.xda-developers.com/ga...ol-updated-09-06-14-efs-professional-t1308546
1. flash combination files.
2. in IMEI option type +#0808# select DM+MODEM+ADB then leave the modem option showing next, then restart phone.
3. open EFS Professional, select Qualcom option, then your phone should show on com ports, then tap connect, Secure OPs, tap send password and the imei should show, right there you can change it or restore it from the original. tap write to phone. disconect and then turn phone off.
4. check imei +#06#
