Yep, should have ... that's why it's in the instructions.

Better late than never though. Caty will say typical males. One didn't read the instructions and the other one correctly guessed the first one didn't [probably because he wouldn't have either] ......
She even put it in red.

Hi, and thanks for nice detailed instructions.

I have flashed my Nuvi 3790 HWID 1101 from Europe with nuvi34xx_GCDFile__820.rgn via RGN tool,
all was fine and also did backup NV to sd, before flashing.
Now I got problems getting into pre-boot mode Again for flashing logo with 34xx_350_logo_hid1376.rgn,
I try many many times with no luck.
Could it be possible to flash 34xx logo and enable all features via sd Card ?

Thanks in advance.

Hi,
you missed probably this in OP:
Go to MTP Settings and set it to Mass storage mode.
Setting it to Storage mode you'll be able to flash the new 34xx logo in preboot mode with updater.

Could it be possible to flash 34xx logo and enable all features via sd Card ?

Thanks in advance.
