None of my sensors work?!?!

Latest cm 10.1 nightly
latest franco kernel nightly
just updated to latest bootloader and radio from 4.2.2
and none of my sensors are detected such as light and accelerometer. I downloaded the app android sensor box to make sure.

THANKS! I'm assuming it has something to do with the new bootloader/radio?

I think its the new baseband that's breaking lte sensors and rotation

Okay no my wifi isn't connecting??!?! Is there a way I can just go revert back to the older bootloader and radio?
This fix breaks wifi for me. My phone just sits on "obtaining IP address".

If ROM flashing doesn't help which didn't help me flash Google factory image of 4.2.1. There is a toolkit somewhere in the forum or search on Google nexus 4 toolkit you will get all the instructions how to flash factory image. Hope this will help you

Try going into the stock recovery and wiping the cache. If that doesnt work, do a factory reset using the stock recovery.
I tried do what you suggest but still don't work :/

there any different between the versions ? 48/54 and 84
Not much I've used all of them. When I flashed 4.3 I did it with images from the Google page in bootloader mode. I updated all my Android pc software "I use Windows". I locked and unlocked, then flashed in bootloader. I had one issue I missed spelled something but very thing went well

Try flashing the 4.3 baseband and see if it loads. If it does then I suggest you use a hybrid baseband by morrislee.

Auto Rotate problem

I was with Kitkat German, and suddenly - when I tried to rotate the screen, he also turns around, but he did not turn around right .. and the camera takes pictures upside down, even when I went back to -4.2.2 same thing and not solved ..
Access Warranty?
UP
It's the kitkat modem that messes up the auto-rotate and some other things, have you tried downgrading the modem if possible? Download a flashable zip for the previous modem and flash it via recovery.
Link please for old modem?
thanks.
I'm currently having the same problem. The old modems are not working.

I installed the old modem and now the screen does not turn around at all.
You need a Kitkat baseband for a Kitkat ROM!
Some folks reported that recalibrating the gyro helps.

I can't recalibrate it. The settings app force closes if I try too.

I would prefer flashing the rom new and to not mess up with different basebands.

can't update anymore

I recently flashed back to stock 4.2, and now I can not update to 4.3 or 4.4. I tried using OTA and flashing through CWM, but no updates will flash. Anyone run into this issue?

Microphone issue

I have an Indian variant Note 4 running marshmallow 6.0.1 with the latest updates.
I'm experiencing an issue related to microphone.
When my phone boots microphone works fine but if i don't use my device for some time like 2-3 hours then i could use microphone only for voice calling but not for internet calling(WhatsApp, fb messenger,Skype,etc) and for recording audio or video. Also cant launch okay google with hotword during this time and unable to give voice commands. Then when i restart the device microphone starts working completely fine for all these.
help guys.......??

If you are in Stock rom just boot into recovery and do a factory reset (this will delete all the apps and data )

Then it's definitely a hardware defect you may go to the service center and check
