Hi everyone,
I recently upgraded to Sync 3.4.23088.
Everything was fine but suddenly many issues like black screen on start, master reset nor working and screen frozen, impossibility to push on any buttons, etc…
My idea was to insert the USB stick with the Sync 3.4.23088 version that i used to upgrade 2 months before.
And then i got “INSTL_ЕRR12”.
Could someone help me please ?
I was told that the problem is rwdata or something like that.
