I have Part number: JS7T-14G371-JHG a MY20 unit that I ran the updater and got a black screen. I mistakenly followed advice from AI. I know this was my downfall. Lesson learned. I followed the link that was sent to me to try to get the screen back, and I have the unit back in reformat mode, asking to put in a usb drive. I am trying not to make the same mistake as before and just don’t know where to go from here. Any help would be appreciated. This is a non nav unit. I’m fine with going back to 3.0 if that is an option.

SYNC Region: NA

That’s great, do you have a picture? If its the normal reformat screen, you just need to connect the USB you creates, which was a reformat USB if I recall correctly. But share your screen before moving forward…

I tried the original usb stick I made with the syn3updater but then get the below message.

Error failed to partition eMMC… After this screen I can remove the USB stick and it boots back to the Please insert USB stick… screen.

This is not good, usually associated with a hardware issue…

Was it you who recovered it with the method from the other thread?

6

Yeah, it was me.

Sadly, it does not look good…
One thing you could try is a different pendrive, we had issues with PNY in the past, but I’m not sure if that would trigger such a failure.

8

Is this the same MY20 APIM that you used originally? Your trying to reformat it again?

Yes sir.
