jay.miller2009 · April 1, 2026, 3:39am

Reverted to the original 4" screen after upgrading the 8", which bricked after 1 yr.

SaNdMaN · April 1, 2026, 3:55am

Is there a question here?

jay.miller2009 · April 1, 2026, 7:30pm

Yes, I reverted to the original 4” screen and need that software. The several ones I tried did not work and kept the 8” touch screen software.

SaNdMaN · April 1, 2026, 9:20pm

Install NU5T-14G381-BB, which is the latest 3.4 for 4 inches I’m aware of.

jay.miller2009 · April 2, 2026, 3:05pm

I’ll try that again. After I loaded -BB the resolution was still incorrect. Any thoughts on what may be the issue?

SaNdMaN · April 2, 2026, 3:09pm

Get -BB installed, if it’s still wrong take a picture of the screen and share the interrogator log file.

jay.miller2009 · April 2, 2026, 3:32pm

Will do…itll take me a few days as I’m out of town for work and will have access to my van next week…Thanks for the info…

jay.miller2009 · April 8, 2026, 3:00pm

I cant see to clean off the 8” software…any help is appreciated…I tried that file (-BB). No luck. Tried NU5T-14G381-BB_1665526155000.TAR.GZ as you recommended.
Ran RWDataCleaner multiple times (2–3 passes).
Still getting PKG_ERR04 on reformat.

That tells me nothing.
That’s why I mentioned before:

I got the file, thanks but explain your current issue.

jay.miller2009 · April 8, 2026, 4:34pm

NU5T-14G381-BB will not load. I get a PKG_ERxx…can’t read the full error name on the screen due to the resolution mis-match. here is the log

Sync_V01X00F5_1FBAX2C80MKA13617.xml (10.3 KB)

SaNdMaN · April 8, 2026, 5:26pm

Share a photo either way.

But without a proper error to work on, I would recommend using a good USB pendrive.
Also share:

screenshot of the USB’s root showing files and directories created
screenshot of each .lst file’s content, these are located on the ROOT.
screenshot of the SyncMyRide folder’s content

Make sure extensions are shown.

jay.miller2009 · April 8, 2026, 5:56pm

SaNdMaN · April 8, 2026, 5:59pm

That was never going to work, you are trying to reformat the unit running a 3.4 where the reformat package is blacklisted.

I just said to install NU5T-14G381-BB, I’m not sure why you have the reformat tool in the autoinstall.lst file as well.

Get the proper autoinstall.lst file either by editing or just downloading it from the -BB link.

jay.miller2009 · April 8, 2026, 6:03pm

Heres the cleaner file I tried before loading the software:

SaNdMaN · April 8, 2026, 6:04pm

Do not take this the wrong way, you are doing whatever you want, and not what I’m telling you to do.
So please, take your time, read what I’ve said and act upon.
If you have any doubt, just ask.

jay.miller2009 · April 8, 2026, 6:07pm

Ok, I see I have the two other files besides the -BB file. I will only add the -BB file to the USB. I’ve downloaded the associated Autoinstall file and see it only loads the NU5T-14G381-BB

I see what you are writing and will try just that.

SaNdMaN · April 8, 2026, 6:08pm

That’s correct. You can have all the files you want inside the SyncMyRide folder, but they will be only referenced by the .lst file on the root. So you just need to have the correct .lst file on the root and the referenced file inside the folder. That’s about it.

Give it a go and share your results.

jay.miller2009 · April 8, 2026, 8:26pm

I loaded the file and the system rebooted but now the screen is blank.

SaNdMaN · April 8, 2026, 8:27pm

Is the unit operational? (like audio, powered USB ports, a splash screen when booting).

jay.miller2009 · April 8, 2026, 8:29pm

Yes all of those work.
