I found the following on a Jeep Forum, I may try this next, what do I have to loose? I may need to replace my Uconnect anyways:

TL/DR: take out the radio (panel comes off by gentle yanking, radio comes out with undoing four screws using 7 mm hex socket), split it open (using T10 torx screwdriver bit), clean the AirPrime/AirStream connection (the one that looks like WiFi connection in your laptop/desktop/cellphone circuit...

( I just bought my first Jeep Grand Cherokee 2014 4x4 Limited a couple of weeks ago and am very happy with the purchase! The car runs smooth with 149k on it, but I noticed that the radio was acting funny at times: it will not turn on during the first few minutes of the drive (and so no backup camera), sometimes heated seats and heater will turn on automatically, and the GPS would just not work (it could get the time correct within a few minutes, but will never lock on a GPS location and will not show any satellites under Nav > Where am I > GPS. Frustrated, my wife called UConnect support (using the number displayed on the screen itself, whenever it turned on) and the customer service rep advised on updating the version from existing 17.11.37 (I think) to the newest version (18.45.01 was available). She delegated the task to me and since the recommendation from the source (UConnect), I quickly downloaded the update (from
here) and started on flashing the radio, and did not bother pondering on "what could go wrong?". BIG MISTAKE! Lo and behold, at 15 minutes through the update, the software froze on 67%, at the start (1%) of section 11, Embedded Air Card.
After about 10 minutes, the failed update message came (Sierra Wireless: bolo file install failed), and the next I knew was I was in the infinite bootloop!
I did not have patience or inclination to keep the Jeep driving around in the hot summer without AC and attempting to get the software update done after 20-30-40 attempts. Luckily, I found
info by @trever.b.chapman, leveraged from
another forum, that a custom(?) swdl.upd which apparently skips embedded air card update can go through the process and gets the update through the end. I could successfully update the software, after spending 2+ hours, but that did not address the problems I was having: It felt like the radio has a mind of its own and doesn't start with the start of the car even after the updated software and GPS fix was still not achieved (I didn't drive long enough or multiple drive cycles to notice heater on and heated seats on issue).
The
post by
@JJBBQ in the same thread suggested to disconnect and reconnect the airstream card (on his Dodge Challenger) to address this issue of failed update and I decided to give it a try the next day. It turned out to be way easier and faster than I thought. Here are some of the steps (some screenshots from
this youtube video - but you are NOT removing the bottom part - only the radio/infotainment system!):
1. Take out the radio panel trim - the easiest way I found was to open up the cover in the bottom (where there is a charger port and SD and USB card slots), and gently pull it from the bottom. No need for any pry tools etc! Make sure you unplug the cable connecting the instrument panel before you pull it all the way out.
2. Undo the 4 screws that is holding the radio/infotainment system using 7 mm hex socket.
3. Unplug all the cables that are connected to the radio - note that there is no pink (GPS?) cable and that there is one extra blue cable that doesn't go anywhere.
4. Split open the radio by undoing 4 screws using T10 torx screwdriver bit to expose the cable to airprime/airstream card - careful when you split it open not to make any damage to this cable!
5. Unplug the airprime cable and clean it with QD electronic cleaner (absolute alcohol works too - any contact cleaner should work. Avoid touching the connections contact area with bare hands/skin, as you might accidentally put your body oil/fat which act as an insulation and therefore is not good for these electronic connections.
6. While on it, clean ALL the connections (the two panels inside the radio, the 5 connections on the back of the radio, the 2 connections on the back of the wall as you see in step 3 pic) with this cleaner (the spray is less than 10 bucks, and it might be sitting in your garage already!), let it dry (takes a couple of minutes at the most), and close it all back by going through the steps above in reverse order.
With this, my radio came back to life, and now it starts as soon as the car starts, doesn't act funny with the A/C etc., and GPS fix is less than a minute (so by the time I reverse the car from the driveway, it is ready for me!) Since I already did the update on the software, I did not attempt the update again, but I am pretty sure that now it won't have any issue with software update either!
Save yourself from thousands of dollars and hours of back and forth with the customer support and dealerships. This will take less than an hour all together to fix your radio!
Thanks
@JJBBQ and @trevor.b.chapman (and
@djmjr77 on XDA forums) for the leads! I am not sharing anything new here, but hopefully the step-by-step guide with pics would help someone who is not very handy or doing any sorts of tinkering for the first time! )
