Re: 8.4 UConnect Update - Deconstructed

So.. I'm always into looking around and tinkering with things...

And after reading many forums and sites on the uConnect exploits, published in the hacking PDFs, etc...

My Current system:
Aussie MY14 Laredo RJ3 uConnect
Firmware v15.26.1 - RJ4.
NAV activated with 3D Maps - tho the 2012Q2 maps are ancient.. glad I did not shell out $$$ to dealer for this.

I have so far managed to perform the following:

1. Load up an "edited" Original ISO file and perform my own scripts/changes. Yes this works on the latest firmwares, as the ISO "passes" validation, and the system allows "downgrades" to run.

2. Dump the entire filesystem out to USB stick, for looking at, and also helped me do below actions.

3. I have managed to successfully "convert" my RJ3 RW model uconnect to other models, such as RJ4 RW unit. You will see below why I wanted to "convert" it...

4. I've managed to get the update ISOs to install the "uConnect Access" / Apps, however they are pointless and do not work, as they need the Sierra Wireless device for internet access - and they are not activated unless you can connect to uConnect Store.. which requires the internet connection.. I have read tho you can buy a LinkSys/DLink USB to ethernet dongle which gets enabled during bootup of the uConnect.

5. Since I own a MY14 Laredo, my NAV was not activated (RJ3).... I have now activated my NAV and updated the MAPS using the RJ4 Maps Update ISO... and yes, I have 3D Maps. As for their reasons why they say the "activated" RJ3 NAVs "cant" get 3D maps is beyond stupid.. I checked the filesystem free disk space using "df -h" and it had 4gb of free disk space before I uploaded the RJ4 Map update disk.. after checking it, that 4gb dropped to only 3.3gb free space... The only thing I can think is that possibly the NA or EU maps are much bigger in size, and would not be able to fit.. luckily for me the AU maps are only quite small.. maybe 1gb in total...

I am currently working on the following.... most of which I am digging through the Update ISOs that I have managed to download..

1. Enable SRT App - I know customtronix have this, so it must be able to be done... without paying bulk $$$ to CTX for a token / iso file theyve put together.. No offence - kudos to them for working out how to make their own custom ISOs - but I'm not willing to pay 130 euros for unlocking SRT app.. their "Jailbreak" doesnt even do NAV activation..

2. Enable DAB and get antenna sorted - Seen the post in the forum about this.. I did have the DAB button before I started all of this "hacking", not sure where I lost it.. but I never really looked into it much.. it did show up and stick around after factory reboots, and I could go into it but wouldnt find the stations - as shown in the other thread, you need the antenna hooked up for it to function 100% on the jeeps that get this DAB icon all the time...

3. Change the Splash screen pic, bg images, and more... I assume this would be easy - but since this is really a low priority for me I've not really looked at changing these files.. I assume it would be as simple as replacing the Jeep.png and Splash files I have located, with what ever I like... will probably look at this soon..

Phew... what a post.. sorry to blab on a bit. Hope this info helps any more people out... if they want to talk to me more about it, willing to chat.

I really want to know how to do this. Been struggling trying to compile an iso that will pass verification. I like you appreciate the other solution from ramtronix, just am unsure parting with that amount of money for a modified iso. Any help you could give would be greatly received.

Have you read through the other thread here:
uConnect 15.26.1 is buggy; I want to downgrade.

They helped me out a lot to get a working ISO...

Basically you need to grab v14.25.5 or below ISO for RA4 North America.. I used 14.05.03. Then I used the Script Injector created by vecais_dumais_laacis. I tested it out on the ISO I had and confirmed it had modified the system_module_check.lua script properly and cleanly, I got the lua script to execute mmc.sh start/stop as detailed in that thread, and inbetween that, it runs lua script from my USB stick.. /fs/usb0/script.lua which I can then get to do whatever I like before the update stops.

Then you also need to add the magic "S" marker using a HexEditor at the byte marker detailed. Depending on your uconnect region/model, I also had to comment out the checks for Region/Market and models in the system_module_check.lua also using a HexEditor so it simply passed all checks - since I was using a RA4 North American ISO on my RJ3 Australian uConnect.. it was easier to use that ISO because it is much smaller in size (580MB compared to 1.4GB), and the Injector Script doesnt need any modifying to find the right byte markers to modify (I'm lazy).

After that you have a 100% working update ISO, no more need to modify this ISO - as you can then just modify your LUA script from the USB stick and run it everytime, until of course you get to a better position (i.e. enabling SSH with Wifi or similar).

After digging around in the filesystem I worked out what was required to activate navigation on my VP3/RJ3 unit. Ran the Nav update ISO to update the maps to the "still outdated" 2012Q4 revision for Australia... still better than paying $600 to someone off Ebay or even more to a local Dealer.

Re: 8.4 UConnect Update - Deconstructed

Sorry but you've lost me. I read through all the posts but am missing how i run the script. I have the script but am unsure how to proceed further. Maybe too much out of my realm...starting to seem that way. Any further help would be appreciated. All i really wanted to do was change the stupid longhorn background and enable srt apps because i have the proper NA version of the RA4. Thanks again for the direction

No worries - sorry I couldn't help out.. I've not yet looked at changing Background images, or enabling the SRT Apps... from what I have read tho, the Customtronix Jailbreak wont even enable SRT Apps for a proper NA RA4 unit either. So not sure if you could even do this on a NA RA4 unit at all..
