I also have problem with signal drop on Pixel 6. My phone unlocke bought in Germany and I use it in Serbia, A1 is operator.
I am totally new in this matter And I would ask someone to explain the procedure of flashing radio.img to me
What I did so far :
1. I downloaded Platform tools r31.0.3-wondows and unpacked it,, now I have folder PLATFORM-TOOLS.
2. I downloaded 12.0.0 (SD1A.210817.037, Nov 2021) fw version for Pixel 6.
3. I renamed file Radio-oriole g5123..................img to radinov.img
4. I put the file radionov.img in folder PLATFORM-TOOLS
5. I turn on usb debugging on my phone
6. I connect my Pixel 6 by usb cable to my windows 11 laptop.
And now....I need your help....as I understand I have to put command from cmd prompt...but I am am not sure about which command
Can someone help me...step by step....
It looks like it was manually installed to me.

If you already have so much time to follow mine then read carefully. What I wrote about was my goal to do downgrades to the November firmware. I've never done that, so I asked for advice ... So, do you want some more proof...
 
By the way, the title of this thread is misleading.
There was never a December Over The Air update.
There was a December factory ota image for download and manual installation.
I got the december Update even over the Air, Just searched for it and it was offered here in Austria.

Now with the january update, all seems fine. I use 2 Sims. Good reception and good battery health/runtime.

Same for me, with the December update I had zero signal at home.
Now with the January update, I have comparable service with my wife who is still on the November release.

I have had my p6 since launch day so am reasonably familiar with its ways. Iinstalled the January OTA without issue on my p6 and have seen some immediate improvements.

My signal strength including dropping of calls has really improved.
Battery performance has improved Considerably.
The finger print reader is a bit faster and more accurate. (No protector fitted)

Can’t really comment on whether the phone is any faster as that was never a problem for me.It does feel like Google have probably saved the day with the January update. If they had failed to deliver I suspect this phones reputation would have suffered long term with 2nd hand resale values dropping too.

Im finally a happy user.

    I guess if the world was going to definitely end tomorrow.
    People would still be worried about getting the January update.

    Lol...
    No one would know. We have no cell service.

    @djoka60 @m-j-s I agree, this is not a solution long term nor is it acceptable that Google didn't fix this immediately. I was merely commenting on the blanket statement confirming this is not a solution. It does work for some and for some it did not. Thing is it is worth a try and "confirming" it doesn't work would preclude some from doing that. That point is now moot since they pulled the beta signup but you can download it on apkmirror last I heard. Not sure about that now. Even if, and I'm sure you're right, the majority of users are not experiencing increased signal it means that some are. I can confirm that. ;-)

    Semantics aside this December update was a total disaster including some now deprecated (or disabled) major features of the Pixel phone service. It's almost 2 weeks now and not a real fix in sight. I'm not sure what they are thinking at this point. I almost wish I'd held onto my Pixel 5 now so I can wipe the smile off my wife's face as she twirls her P5.

    Of course she has no clue.. she's the lowest person on the totem pole, trained to answer questions like "where does my SIM card go in?"

    If people want to get Google's attention go to the link @pemz82 provided https://issuetracker.google.com/u/1/issues/210484323 and star the issue.

    I just want to confirm that since the last Update the reception of the phone is much worse, There is a room at home where it can not be used any longer.

    How to go back to the last update without deleting all Data?
    If your bootloader is unlocked you can simply flash the radio image from your previous version. If you're not unlocked then don't do it now since unlocking will wipe all your data!

    Download the November factory image from here.
    Open it, unpack the radio-some.long.number.img and rename it to something shorter like radioNov.img
    Copy it to your adb/platform tools folder and flash it with fastboot flash radio radioNov.img

    That's it - my P6 went from 0-1 bars with the December A1 update (and A4 was just as bad) back to 3-4 bars with the mid November 037 radio.img :cool:

    Frankly i don't understand why google are doing this. Ok it is new custom chipset and new software - bugs happen. It is normal. The way this should be handled though is much different than what we are seeing and it is pretty simple to do:

    1. Stop the OTA update rollout immediately. Google did that more than week later and they also acknowledged the bug around the same time which for me was unsuccessful attempt to hide the problem.
    2. Publish news acknowledging the problem and remove the link to the OTA files so that people do not sideload the problematic update not knowing about the problem.
    3. Push update for the affected devices reverting the radio firmware to the november version till the problem is fixed.

    If they did that people would be ok and give them needed time for proper fix in the january update. Instead of that thousands of their customers (looking at the issuetracker comments alone) are left for almost two weeks now during the hoilday season with flagship devices that can't even make phone calls properly and without any information when problem will be resolved. I myself was on vacation when december update was pushed and this saved me. I did not get OTA but i would have sideloaded it if i had access to pc and may have been in the same situation. I like to be early adopter and can wait for some bugs to be fixed as soon as at least the basic functions are working. This is why i was so excited to switch to google phone. Well it looks that i will think twice and research before updating in future.
