MOTOTRBO High Pitch Noise - CONTINUED

[tgbanshee]

Looking for a special version of firmware released for the Motorola XPR6550 to fix a known issue with the radio where it will randomly emit an ear piercing high pitch squeal. MOL is being difficult and is stating that "the radio is no longer supported" and are refusing to supply this firmware. Several times I have been deafened by this this issue (to the point of tinnitus) and I use the radio quite frequently so I am desperate to get this bug fix firmware.

The firmware has the following special version number:
MOTOTRBO update: "MATRIX 1.12A Subsciber S01.17.08_R13.02.03"

Any help would be greatly appreciated as MOL support has been extremely disappointing lately. This is a known problem with an official fix from MOL which they will no longer support (likely so they can sell newer hardware). See the following link for additional information as it has been discussed here once before but was several years ago when the radio was still supported by MOL:

I got it on that P25.Ca forum a year ago. Put it in a bunch of XPR6580’s last week. I’ve only experienced the noise twice in 8 years.

Great, so why not share the file?

Since MSI doesn't support the radios anymore, no harm in sharing the firmware. Here you go.

You are my hero, thank you so much!!!

Any chance that someone still has this around? The file is no longer on Mega.

And indeed - M refuses to deal with this directly since the radios are out of support.

Would you please share the file again? I'm looking for this firmware as well. Thanks a lot!

tgbanshee- this happened a couple of times on a used xpr6550 I bought. Question: do you have a Motorola or aftermarket battery? Since I switched to a Moto battery I haven’t had the issue but we know it can be sporadic.

I experienced the issue with multiple genuine IMPRES batteries. Upgrading the firmware to S01.17.08 is the only real fix.

Is S01.17.08 a newer firmware than R01.12.17? S comes after R but 2017 comes after 2008 or maybe the .08 and .17 are not the year?

 

[GTR8000]

S = Service release. No, it's not the year, it's major and minor versions. S01.17.08 is the most recent and last firmware that was available for the XPR 6550, and was not publicly released.

The firmware is not showing up in the dropdown list with the other firmware. It's been a while since I loaded firmware, any tips?

My bad, i forgot the firmware comes with an installer

FWIW - Windows Defender blocked that file claiming that it contained a trojan.

Scanned the file with McAfee and Malawarebytes and it was clean. There is something online about false positives for wacatac (not specifically wrt Motorola firmware) and i did not dig into it.
