I hope because I never tested the pre-boot mode of my unit .
So I don't know if I can .
I explain my work
I open with rgn_tool the firmware of the nuvi
then change the boot.bin
then change the hwid to 1083
then change the firmware version to 2.53 ..... the original was 2.50
so create the GUPDATE.GCD
This evening I test to send my original firmware with updater
If is ok I test late the modified firmware with updater
Is good work ? May be yes ....
