I have a chinese 7" GPS manufacturer and model unknown that is stuck on boot image after loading miopocket.
I opened the unit and its hardware shows model YG-912D-ABFSJ-1M-AS-4LS-6LS-V2.2, I have downloaded the software update zip file YG-912D-ABFSJ-1M-AS-4LS-6LS-V2.2.rar and extracted to root of micro SD (had to take out of top level folder called OS that it was extracted into) and installed card in unit but after power off and on and also pressing reset button (which just turns the unit off) I can't get the unit to start any flash upgrade and don't know what I am doing wrong or even if I have the correct files etc.
Files extracted to card are below
912D_SD_S.nb0
gpstest.exe
jwdupdate.exe
Folder called update with various files within
Also I cannot activesync to unit as I get "error 608", please help
Is there a way to hard reset/restore to factory
