Hello,
Currently i am running the latest version of CM13 (cm-13.0-20160307-UNOFFICIAL-Z00A.zip ) on my phone, but this issue also occured with the other versions starting from the 1st of march.
With 2 sims inserted in my phone, both of these sim cards work fine when i put them separately in the phone, however when i put them both in some weird issues occur.
The problems start when booting my phone, the phone asks me to enter the PIN for sim 1, which works and connects the card to the network ( and fetches my latest messages and such )
Then the phone obviously asks me for the PIN of my second sim, which it accepts. However after accepting my SIM the same popup comes up asking me for my PIN for sim2 again.
And when entering the PIN it gives me the error : "SIM PIN operation failed".
After multiple attempts, it finally gets me in the phone. However the data on SIM1 is not functioning anymore.
What i've tried is:
Multiple different CM releases from the past week
Putting my phone in airplane mode and out again
Factory reset the phone
Does anyone know how to fix this issue?

I own an Android Developer Phone1 and have been working with it sans problems.
Once I tried to flash the OpenEclair 2.0 and succeeded in that. But as the performance was sluggish, I wanted to restore the stock ROM.
Accidentally I flashed drea100.nbh and my ADP was downgraded to a retail phone. After a long struggle I somehow managed to restore the original ADP bootloader.
But, now I have a problem. The phone does not recognize any SIM cards.
I thought the hardware might have gone bad, but found the "Lock SIM card" checkbox ticked in the SIM card lock settings.
I am unable to uncheck this, as it is asking me for the PIN and even if I enter 1234 or 0000 it is saying wrong PIN. Can someone help me remove this lock?
So I recently tried to root my phone but failed and had to factory reset. Afterwards, the phone kept saying no service on bootup. Then after 15 minutes, it connects with Telus and I have service again, but seriously..15 minutes?
I found out it's because the sim card locks up everytime the phone restarts. I could easily unlock it by going to settings > location > change sim state, but it says I have "0 attempts remaining" so im pretty screwed over.
As far as I know, it should at least prompt you for the pin during startup, but I don't get that either.
it's not a big deal cause I never shut my phone off but its only a week old so yeah, don't want a buggy device
*******BUMP*
i have a brand new phone and setting up tethering puts the phone into a bootloop. I have tried this 3 times and it's same result. Each time, i have had to go into recovery and reformatted it.
All i do is change the SSID name and a password, a few seconds later and it reboots
The phone has a serial number starting with 511... (Manufactured November 2015)
Anyone with a similar phone want to test it out as it's basic function.
Phone is running masrsmellow
Hello,
I was using for 3 years this rom https://forum.xda-developers.com/optimus-g-pro/development/mar-0-lollipop-g-pro-v1-t3043779
Yet after deleting some photos, clearing cache of bluetooth (in apps section because it gave me "unfortunately bluetooth has stopped) & restarting phone I couldn't insert the pin.
So flashed stock rom = yeah it works.
Then decided to clean install same rom I been using for years mentioned above https://forum.xda-developers.com/optimus-g-pro/development/mar-0-lollipop-g-pro-v1-t3043779
It showed my imei but the moment I insert the simcard it still didn't let me write PIN & imei + phone number went to "unknown".
ps. also the moment I turn it off at the end, my phone gives sound of mouth chucking lol wtf
Help welp....

Swapped sim slots sounds like what happens when downgrading to Oreo. The fix for that is to use a newer (pie) modem partition.

I see a more recent thread complaining that sim 2 does not work. I only use sim 1 and it works for me.
Did you try turning the phone off (not just sleep or reboot)? My data connection almost always dies when I install an OTA (probably TWRP). Turning the phone off and sometimes leaving it in airplane mode for an hour fixes it.
In my case, the network is rejecting data connections (call and sms works). This was not in the regular logcat...
adb logcat -b radio
