My questions/problem
1. except for step 4 & 5 which i drag the .gcd & .rgn to "webupdater" it seems to update but when i power off/on the unit the software version is still 4.90 (the downgrade & conversion is not successful right ?)
2. i then delete the gmapprom.img that came with the unit and replace it with gmappromTH110.img renamed to gmapprom.img is this step ok
3. i copied JCV110TH.jcv on to the unit
4. When i turn on the unit it able to display the map manage to simulate route but when it reaches the junction it just shutdown, is the jcv not compatiable?
5. Next i tried play around with the icon, i think the last one that i play with was ecoroute then i turn it off, this morning when turn on the unit it just start up for short while (it didn't reach the gui screen) it shutdown, how should i solve this issue ? Note: I managed to get the updater.exe should i redo the 7 steps again
6. For step 6 how could i check the checksum
Thank you
