Question P6 no longer sees simcard; likely after the November security patch

[gariac]

The TLDR is the Wednesday before Thanksgiving my phone indicated no service. I think I had allowed the November security patch to go through in the morning. In the afternoon I noticed I had no service. At first I thought Google Fi was messed up so I spent some time with tech support trying to get the esim and/or physical sim to load. Eventually I put the Google Fi sim in my old One Plus 5 and proved the Google Fi service was fine and my P6 has some issue.

The phone can't "see" any tower. You run cell mapper and nothing is seen. In setup the physical sim is not seen nor is the esim. In fact I can't even see any IMEI numbers.

i decided to flash the Android 13 OS from the google website. I run Opensuse linux and have adb installed. The flash worked fine but still the sim card is not seen.

reddit thread

I have this reddit thread going. One person has the exact same problem, sent the phone to google and they sent it back not working,

I see there are beta OS for Android 13 and also older Android 12 images. I noted the rather complicated warning about bricking your P6 and will admit it is beyond my understanding. Basically I did the normal OTA update which is differential then flashed the full current Android 13 image.

Any ideas? Should I try to go back to Android 12? Is there some firmware I can flash.

Someone might want to let that reddit thread know that upon updating to Android 13 you CANNOT revert to Android 12 without hard bricking the unit. With Android 13 the bootloader was changed to prevent downgrading to Android 12.

Ok that i will do that post.

BTW did I do any harm by flashing Android 13?

 

[Strephon Alkhalikoi]

Nope. Android 13 fixed a lot of annoyances found in 12. Both the P6 my roomie uses - my former phone - and my P6P took the Android 13 update without any issues.

I have exactly the same problem, since the november update, it's like the modem died or something... I removed the sim card from the P6P and use it on the pixel 4a; pixel 4a runs smoothly; I hope the December update fixes this... But I'm pretty sure it won't.

 

[Mykmen]

Was this fixed?

No, I think that the december update will came in a couple of days...

 

[Mykmen]

How often is this happening?

I haven't had service for 2 weeks, since I upgraded... before I had connectivity issues, but since the upgrade I've lost all connectivity

Just a FYI, Google Fi is trying to get me to pay $79 even though my phone is only 6 months old. This is crap of course. I suggest not clicking on the agreement for this fee if you swap the phone. You click it and they will charge you.

I have yet to get any feedback from the bug report I uploaded. I am going to phone Google Fi rather than deal with the chat. Perhaps the tech support is different.

I'm not sure what happened but my phone stopped recognising the sim card last week. After trying a series of different things, I eventually got a new sim card from my phone service provider and once it was activated everything was working again. It could just be a coincidence because I don't know how the update could have corrupted my original sim card but at least everything is alright now.
