UPDATE: SUCCESS!
I can verify 3.4.23188 works. But only if files are NOT corrupted. Consider this issue closed. Longer explanation below incase others experience this problem.
I utilized the autoinstall.lst mentioned earlier to build a carefully verified usb drive with the correct 3.4.23188 tarballs. Because i received corrupted files from ford. Now works on my 4 inch display.
Here’s what happened:
- installed evening of july 4
- at one point, the device rebooted to ford logo
- then display went black
- i continued to leave car running for another 45+ minutes. Screen remained black.
- i assumed it failed. Shut off car
- july 5: drove a few miles that morning. Display still black. Shut down and parked until…
- that evening: back car out of garage. And display suddenly working
Basically: give your install alot of time to work.
If you have verified your usb has no corrupt files, then don’t be afraid to retry if necessary. Unfortunately verifying you have uncorrupted files can be a challenge for the average person without appropriate technical knowledge.
