No SIM recognition after OOS 10.0.1 update - EFS problem??

[yeyitin]

Hi,
I have my 5T rooted with Magisk and TWRP recovery.

I've upgrated from OOS 9 to official OOS 10.0.1 flashing with TWRP as usual. I did a full nandroid backup before.

Everything went fine until I noticed that during the booting of the phone after the flashing, it didn't ask for the SIM code as it used to. And once the mobile had fully restarted, I could see 2 new icons on top of the screen picturing the 2 sim cards that can be contained in a OnePLus 5T. They were striken through, as if not present, when I had My SIM in Slot 1. And so, no mobile signal, no data network.

I tried switching Sim cards with another mpbile. My SIM worked fine in the other mobile and the other SIM was not recognized by my mobile.

I've read that I could be facing problems of damaged EFS. So I tried restoring through TWRP the EFS partition from the Nandroid I had done before. Nothing. Same thing with the modem partition. Nothing.
I tried then to restore the EFS from a safety backup that I had using Fastboot. Nothing.
I could still try to restore the full nandroid backup done at the beginning, but I forgot to take out pin protection code before taking the Nandroid, and I've read somewhere that it could be an issue after restoring the system. I might not be able to restart the phone and be obliged to factory reset, witch I would really like to avoid. And anyway, if restoring with Fastboot did not work, I wonder if the full restore would change anything.

Anyway, anybody has a magic idea about might be happening? A little help please??

Same problem!

I'm having the same problem. I have my 5T rooted with Magisk and TWRP recovery.

I've upgrated from OOS 9 to official OOS 10.0.1 flashing with TWRP as usual. I did a full TWRP backup before, including my EFS partition.

I'm seeing this too:

I did the same thing and had the same no result.

I'm looking for a solution too.

I came across this: https://forum.xda-developers.com/oneplus-5t/help/baseband-imei-lost-t3834334 and this: https://www.getdroidtips.com/how-to-repair-and-fix-imei-baseband-on-oneplus-5t-a5010/

I've been reluctant to try and rebuild the QCN file, but it might work.

Working on this

So I'm working on reprogramming the IMEI using the Qualcomm tools. I was able to use them to back up my phone and see the it still has the correct MEID.

However, the .gcn file linked to below isn't accepted, with a weird error: "The file model MSM8998 does not match the phone model MSM8998. Please select a file for the MSM8998."

I'm not sure what it isn't liking. In theory, I think I could just put the IMEI numbers into the QPST programming tool, but I'm not certain where they would go and the correct format for them (with the chksm at the end or not?).

This is as far as I've gotten. I'm looking for an alternate .qcn or .qcnx (which is the kind the tool generates when saving files).

Hi

I've found a code (*#06#) in a page that gives you the MEID. It worked for me. Hopefully, I have the correct MEID too. The code for the IMEI did not show anything. I'll check the lynks you posted later today.

Thanks for sharing!!

PS. I can not include the lynk to codes page as I'm too junior a member and XDA forums won't let me.

So I've tried te rebuild the QCN file. But my issue is that I can't make the ADB comunicate with my mobile. It is as the mobile was not plugged in?? The usb debugging is activated. I can browse the mobile memory from the computer. But the ADB doesn't lynk with the mobile; when you type adb devices, it says List of devices attached and nothing after. Any idea what might be happening?

What about you rootlessabroad? could you fix it?
