Thread: Convert 3790/3760/3750 to 3490

Looks like succeed in recovering BlueTooth in 34xx. I don't know if it will work always, but for me it worked.
I executed this batch:
xrgn,34,1:/34.bin
ergn,41
xrgn,34,1:/34.bin
Where 34.bin is region 34 backup. From offset 0x10 are not FF, but some info.
And, even startup screen shows 34xx, BT is working.

Yes, it works. That's how I cloned a 3450 device and converted my 3750 into a full 3450. BT looks like it is working but it is not. If you disable it and try to re-enable it in the BT menu, it won't because the BT chip is not soldered on the board.

turboccc,

When you "cloned" the 3450 and converted your 3750 into a 3450, did you end up with full functionality just as if the older 3750 was a 3450?

I have a 3790 and would love to be able to convert it into a 3490 to have the new routing v3.0, but especially to be able to use a GTM-60 with the newer HD traffic features.

Based on what you were able to do, do you think it's possible to convert a 3790 to a 3490 ?

Thanks.

strange that you lost the BT in 34xx ..
I lost it when the model number change to 37xx (not 3760) but when convert to 34xx firmware (it will show 34xx when boot) and BT will work.

Anyway, good to know this trick.

and how to change the model number back from 37xx/34xx?

Nice information for the thiefs BTW any success on flashing asian firmware by modifying region 34/41? I want to see running VDO player on my 3760...

if you like the video player, have to use the 3790V firmware
I can confirm US unit can go 3790v MY/SG
