Hi there,
Try accessing the SD card with another device with stock firmware, if it is working on that device then this issue may be is bcz of your ROM exchange.
Read the full article from where you got your resource to change into LineageOS, if it is a common problem, there must be a solution for this issue.

[Q] Issue with CM10.1 Build - SIM Card

Hello,
I have on my phone now CM 10.1 from here: http://forum.xda-developers.com/showthread.php?t=2682511
It looks and works great on my GT 6500D but when i try to encrypt the phone and add a phone password the phone does not see my SIM Card any more.
Is there any way i can solve this issue? I need the encryption activated on my phone.
If this is a known issue with this build, is there other build i could use?
Thank you

WiFi Issue on LineageOS

Hey, I've got a problem with my OnePlus3T.
When I install LineageOS from https://lineageos.org/ for the 3T, I'm getting WiFi Issues.
It's connecting on and off and I don't know why.
I tested Firmware OB10. 11 and 12 and all of these firmwares I'm facing the same issue with the wifi.
I already installed OOS Openbeta (the latest, 12) and then installed lineageos over it, but I'm still having this wifi problems.
Anyone who can help ?
Can be closed, the normal OOS OB11 doesn't work somehow, but this of Boeffla.

You think it's you who is supposed to fix it?
It's a ROM bug. How are you supposed to fix it on your own?
We devs need to do it. And currently we don't plan to.
By providing custom roms to you guys for free, and wasting our time, we are already doing so much for you. If you enjoy so many things in a custom rom like that, then you should also prepare for facing bugs. That one is very very minor.
Also, comparing custom roms to stock roms is a cyber crime.

Sim card no service after flash custom rom

I installed bootleggers OS, Havoc OS, arrow OS and they all still have the same problem, giving as my sim card without service, I restore it to a stock rom and goes back to normal. Any method to solve this?
The same happened to me with the XT1803 model. it was only in CDMA and the phone was GSM / LTE. I'm investigating the QPTS, but I can't get my PC to recognize it on any COM Port.
Same problem tried derpfest, arrow os, havoc os no Sim and imei
I think the problem lies in force encryption of kernel
I have XT1804
I have the same problem with the above mentioned roms, but Pixel Experience (PixelExperience_sanders-10.0-20200412-2323-OFFICIAL.zip) is working fine.

According to Lenovo, you should use their Windows LMSA tool to backup and restore (if needed) your modem files in the EFS partition before installing a custom ROM. So you'll need to start over and save next time.

No SIM signal or wi-fi after update

Hi everyone,
I have a big issue with the xiaomi.eu Miui 12 20.7.2 and other after this...
After install in my phone (Mi 8) I dont have access sim card. Is like that I dont have any sim card. And no wifi to.
I've done first a dirty install and after a clean install but the problem continued.
After I was rollback to the 20.6.18 version where all works fine! if I upgrade again the problem still the same...
What can I do?
Thanks
Same issue
Hi, I have the same issue, in my case that issue started once I installed Miui 12 20.07.16. I tried installing other ROMs without fix this problem, I will wait until they deliver a new version waiting they solve this problem.
Which TWRP did you use to flash the rom?
I don't think it is a software problem if you have the following symptoms, No WiFi but Bluetooth, no service but detect SIM card, random reboots out of nowhere or when trying to turn on WiFi, unknown baseband and it gets hot, apparently it is a processor SoC solder problem
