You have not provided the log, what you are describing is a black screen after a reformat.
So it seems you ran a reformat on a MY20 APIM/screen, thus killing the unit.
Scott, I received the email to upgrade the unit from CYANLABS. I am attempting to fix the issue. Please help, unit worked fine until i upgraded the software via your email. i have sent the log as requested, any help would be appreciated.
Scott, the is the email i received letting me know to update the software. it is not from you but i mistakenly thought it was. Any help as to how to fix would be appreciated.
This is the email I received follows:
Message from seller CXYMAK: hello, We are customer service. Kind reminder: If your SYNC3 system version is 3.4.22251-3.4.23088, after using it for a period of time, it will cause the system cache to be full and unable to automatically clean up, may causing some options to be unable to save and constantly prompting for default values. This is a system bug, update it to 3.4.23188 will solve the problem. Update method: Please follow the tutorial on this website to update the system version. https://cyanlabs.net/applications/syn3updater/
Let me start over, I am attempting to get help, I have corrected my initial mistake and am not trying to lay blame or give misleading info. The email has a close resemblance to your site, they gave me a link to your site (I sent earlier) and so I thought it was you. My mistake, my error by accident not purposely. I had to dig through months of emails to find so I was going off memory.
I am looking for help, can you provide a fix? The info is from the back of the APIM on my vehicle. I have provided all info you requested, any way to restore the programming? Any help would be appreciated.
