Bluetooth not working after update x940bt

[njdad74]

i upgraded my x940bt unit tonight from version 4, with BT 3.22 to ver 6 with BT. 3.32

 

the upgrade to both the software and BT seems to have gone fine, no errors.  

 

But now i cannot pair anything to BT.  when i set BT on my phone to scan it sees the unit.  but when i try to connect i get the error unable to connect to pioneer navi.

 

when i go to bluetooth settings. the connecttion button in the menu is grey like its unavailable.  

 

If i go to bluetooth audio and hit connect on the bottom of the screen it says connection unavailable. 

 

Any help would be appreciated.  The bluetooth on this unit always worked great before.

I still have the firmware upgrade option available and have tried to reinstall the BT 3.32 software and i still have the same issue. 

 

one thing i noticed is the file dates on the BT 3.32 update are 14DEC2012. 

Can someone confirm this?

Does anyone have MD5 or SHA1 hash of working files for me to compare? 

below are what is in my /FIRMWARE/BT folder of SD with respective hash's

Is there a safe version of the BT software i can downgrade to, back to 3.22? and where can i find that?

This is a common problem after BT updates. The standard fix is to do a hard reboot by disconnecting the battery for a few minutes.

 

BTW, your MD5 and SHA1 all match mine.

Thanks RonS,

 

So i tried unplugging the negative battery terminal for a few and it seemed to have the same result after rebooting.  connection grey out, and not able to pair from my phone.

 

so just for the heck of it i clicked on the registration button and let it scan for nearby devices.   I made sure BT settings on the the phone allowed other devices to find it. 

The unit found my phone, and when i clicked on it it sent my phone a registration msg asking for the pin, i entered the pin, it successfully paired.

So now i can play music and take calls from the phone on my X940bt.  I don't know why it doesn't pair the original way but im happy to have a work around.

 

I cant thank you enough for your assistance.
