Lost IMEI and no sim signal after root

I have the Oneplus 7 Pro it was rooted and worked fine, new update rolled out ( OxygenOS 10.0.5.GM21BA) so I updated and lost root.
I got into the OS everything is ok. Installed magisk root with twrp and when it boots no signal, no IMEI and phone crashes when I try calling someone. wifi works.
Restored stock boot of the above mentioned OS, then everything works, I tried patching my stock boot with magisk, I tried installing from magisk, but each time I lose sim.
Anyone have this issue or similar, can anyone offer some advice, I'm really used to being rooted as my daily driver and even gcam wont work without root.

I had the same problem, and was because I had enabled call recording module in magisk. Disabled it and everything worked fine.

Thank you soooo much, going crazy for the past 2 days without root, you are a saviour.
Disabled magisk call recording, rebooted and all is good.
On another note, is there another way to record calls?

If you are interested I managed to do it with RiCE tweaks, there is an option enable call recording, and it shows up on the native call screen, just tested it works fine on android 10

I will try. Thanks!

I was on the same problem, thank you for the tip to solve it.
I updated my call recorder module to 9.1 and everything is working great.
Just disable (I was on 8.0), reboot, remove, reboot, install call recorder 9.1, reboot, done!

Simple rule, always do backup of EFS partition before all modifications and store it somewhere in cloud or pc.

If probably my EFS partition is corrupted and I dont have any backup, there is nothing I can do? Only have a QCN backup but doesnt work

Try unlocking the critical partitions be4 using the msm tool. Prob have to RMA it tho. There is a write up some where on this, where you delete something and it would rewrite you efs partition but need command below but I'd def read up first this command was used to flash Pixel 2 XL with loader version prior to TMZ20a
fastboot flashing unlock_critical

No problem man.

But the problem still persist

I faced this problem on the exact same build as yours. Disabling Magisk modules all at once solved the problem. Then I tried to enable them one by one until I catched the culprit. In my case it was OOS Native call recorder.

How do I get back to stock Oxygen OS on OnePlus 8T

Sorry for posting this but I have been using AOSP extended for the last couple of days and I want to get back to the stock Oxygent Os. I've Pixel experience recovery installed.
I'm having a hard time finding any usable link to get back to Stock. Can someone help?

You're going to need a PC and MSMtool to restore to stock OOS.

OnePlus 8 TMO Missing IMEI and can't unlock bootloader

Hey yall, I really need some help.
So some back story:
I started using a oneplus 8 TMO version and wanted to unlock the bootloader to get android 12 and root the phone. So I went through the process of getting an unlock token and when I finally got it, unlocked my bootloader, flashed the global version of oxygen os, and got it updated to android 12. Everything was working great. So then I wanted to root the phone so I downloaded twrp, booted into fastboot, and tried flashing it. The phone then booted into the system even though I told it to boot into recovery. After about a minute or so it froze and rebooted into a kernal panic. I unfortunately do not have what it said and cant repeat the process, but it booted into recovery and I clicked reason for boot and it said something about the kernal. So after a reboot it then went into crash dump mode. So I had to use the msm download tool (unfortunately I only had the tmo msm version and thought I could just repeat the process because I had slow internet and didnt want to download the global msm tool) to get the phone working again. So booted into edl mode, reflashed the phone, and it booted up. The problem now is that I do not have an IMEI number. I have a wifi address, bt address, and everything else that makes me assume that the efs partition is still ok (but I dont know enough to debate that) but it does not recognize my sim card. The phone also freezed and restarts approximately every 30 seconds.
And now my problem and what I have tried:
Because I have no IMEI I cannot enable oem unlocking in developer settings, cant flash anything in the bootloader - including the unlock token - and can barely do anything in the system because it only stays on for small amounts of time. I have tried many imei write tools such as qualcomm smartphone write imei, readnwrite tool, fastboot imei writer, miracle box, and I think some others but none of them recognize my phone. Ive also tried the oneplus debloat and oem unlock script to try and bypass the setting but it didnt do anything. I have dialed *#801# and was able to enable engineering mode and diag toggle but it still didnt do anything for me. So I really dont know what to do any more. When in the bootloader or recovery the phone does not reboot, so I can stay there as long as I need. Any help on this would be greatly, greatly, greatly appreciated.

Have you tried using the MSMTool again?

Yeah unfortunately that hasn't worked... I've done it miltiple times with the T-Mobile one and can't use any other one because I don't have an unlocked bootloader... If I had a way to bypass the oem unlocking option in the settings then I might have a chance to fix it but don't know how to do that...

try using this version of msmtool(i use MsmDownloadTool V4.0_Win7 on windows 10). it's a bit newer version(5.2.89) i extracted from OP9Pro file. replace the version from whichever unbrick file you download. worked for me. but don't upgrade to android 12 again, the same issue will happen

Thanks for the response! And I am so sorry but what do you mean by unbrick file? I just had to download the tmobile version of the msm tool. I mean to be fair it was uploaded by someone so they probably pre programmed it but I unfortunately dont have the knowledge for that. I am also using msmdownloadtool v4.0. Do you happen to have the links to what you are referring to?
Heres the link to the one that I have downloaded: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4093043/
Thanks!
EDIT: so once you said that I actually went to the link and there were various versions. So I tried another one and it didn't work but then tried one more and my IMEI was back! I have no idea why that happened but thanks for the idea! I was so happy.

yeah, that's it. it's related to version of msmdownloadtool. some of them must have a newer version. i had the idea from someone else on this forum too. glad it helps. be careful not upgrade to android 12 for now. i think it's because of the way oos12 detects phone varient causing the modem to go crazy. not sure tho. would love to see someone figures it out

Yeah, OOS 12 messed up my phone for a bit until I was able to get OOS 11 back on both slots.

OOS 10.5.22

I converted oneplus 8 TM to GLOBAL. Red Pocket Mobile (AT&T and T-Mobile) worked fine with OOS 11 but just won't work wit OOS 12. I ended up flashing downgrade OOS using an old local update.

Help with busted modem??

This phone was working just fine about 4 weeks ago, and it set in a drawer.
Now the IMEI is totally undetected, won't detect a SIM card and any time I try to access anything dealing with the modem the app just crashes, and the phone just reboots itself every 5 minutes. Does anybody know what I can do? Thanks

Use the MSM Tool as outlined in this guide.

I've already done that. Still the same

If you've MSM back to factory and getting the same results, your device is a candidate for a replacement.
You can always try another SIM card for troubleshooting purposes.
