figured id share my story
i have a 2017 Ram 1500 limited ecodiesel, i bought a UAQ from infotainment 2 years ago (for the carplay feature)
been suffering from the odd freezing, crashing and seriusxm bug since i installed it.. been putting off updating because i didnt have a 2018 vin to get updates..
i was at the dealer asked them to help, they said nothing they could do
i asked the place i bought it from and they gave me the latest firmware 39.6 for UAQ
my first attempt to upgrade gave me error 20
then i read the pdf instructions for the 39.6 update (i know, backwards, shoulda read it first)
i read in the help file very specifically on the second page it said:
"CAUTION! The following procedure is to be performed in the order shown in this document.
Failure to do so may damage the radio and may need to be replacement. The
expected minimum SW version should be IR-22.64 or higher for the update."
and again on the third page:
"CAUTION! If this software is used on a radio with software level under 22.64, it could
damage the radio. If the radio is damaged it may need to be replaced."
my software was at 22.60 as is most people ive read about on this forum
i downloaded 28.3 which is compadable with upgrading from 22.6, then after it finished, i updated to 39.6 flawlessly with no problems
all files are here:
I've heard from multiple people that you cannot downgrade a UAQ radio. This is simply not true. There are some hurdles you sometimes have to jump through in order to complete the downgrade. I'll get to that, but just know that you are not SOL if you updated and something was broken. It CAN be...
