Wireless RSM PMMN4095A Help

[NPeters481]

I have a Motorola Mission Critical Wireless RSM (Blue Dot) PMMN4095A. It has been working fine and yesterday, when I went to power it on it, states "Failure Detected" and the lights alternately green and red then about 10 sec later it shut down. Does anyone know the fix or anything I can do to fix it? It's a relatively new unit and up till now, I have had no issues. I have read on other forums about firmware updates, battery issues, or just a bad unit. Thanks

I was able to get mine fixed. I did a firmware upgrade with a good quality micro usb cable and it took the firmware upgrade and works fine now. Send me a private message and I can try and walk you through the firmware upgrade. You have to have a good quality micro usb cable to make it work.

I tried and followed the instructions of 1 dot/orange button while powering up. It flashes yellow and then goes off. Any trick?

 

[NPeters481]

With mine all I had to do is plug the cable in and let it run the firmware upgrade. I didn’t have to do anything on my mic to make it to the upgrade.

I installed the software. Installed the firmware. Plugged the device in and connected to it and then installed the firmware. No need to push any buttons.

I installed APS, you said install firmware, how do I install that?

 

[NPeters481]

On the link below scroll down to the mic you have and then download the firmware and install it. Then reopen the APS and it should auto recognize it

Just tried it, so far no bueno...unless my cable isn't doing the trick

 

[NPeters481]

I had the issues with a few cables until I had one that came with my unication pager. Not all micro usb cables have all the required wires in the cable. It will start the process but fail half way through.

 

[trafficcop608]

I changed cable and all is working now. Thank you for your help

Welcome. Glad yours is working again. Just remember you might have to delete your BT device on your radio. It might have an issue connecting because if a firmware change. That’s what my local shop told me.

I have the same basic issue only I purchased the PMMN4095a used. I think it is still paired to their radio and it keeps telling me "PAIRFAIL". Any clues?

 

[NPeters481]

I would check and see if there is a mic already paired. I’ve had that issue switching between radios that there’s a mic already paired and it says pairfail. I deleted the other mic in the BT options and it would pair after that.

My RSM was working to I attempted to upgrade the firmware. While it's upgrading, it seems like Windows pop up and go away so fast I don't get to read them. It will sit there and then the APS window will shift. I'll hear the Windows connect and disconnect noise a bunch of times. Then it fails with the X at the end of the progress bar. Figured it just couldn't do the update. I plugged it and went to pair it up and bam! "Failure Detected". I've used almost 6 different Micro USB cables and no bueno. I know the ones that don't have the computer detect the RSM plugged in made sense. I have 2 friends that may be able to help me but I currently have an expensive paperweight which annoys me. Using a Tough ook CF-19 with Win10. Also tried comparability mode to see if that would help. No dice ....

Having the same issue with one I have. Would love to find out what the cause is.

 

[OtakuJon]

Long story short, I had to use a different computer. I first tried to update with my CF-19 Toughbook. When I use my Surface Pro I was able to get the firmware update to work and push through.

Test various cables and another computer if you're having issues. Different computer solved my issue.

What OS did you use on the computer that finally worked?

 

[OtakuJon]

Both Win10 Pro. Not 100% sure why the Toughbook didn't work but it def was an older slower i5 iirc

 

[Phillipsc84]

Definitely not getting anywhere sadly. I have tried down to Win7 and it does the same thing. Worst software I have ever used so far.

I've had issues trying to update the firmware using a usb 3.0 port, but worked like a charm using a usb 2.0 port.
