[Bluez-users] AMBIT T60M665 Firmware Upgrade

[Nuno Cruz]

Hi all,

I have an internal AMBIT T60M665 Bluecore2-Ext on my laptop, and I tried to
upgrade it since it had an old version (16.4), with the genericcsr file (the
dongle is recognized as a CSR generic device), the update went fine but I
lost the blue light on the laptop so I decided to go back and tried to
downgrade, but since I din't the backup I just tried some firmware that I
supposed to be the same as mine from an epox BT-DG02A dongle (the header is
the same - "LOADER=bc02x_hci_1v1_16.4_56, STACK=bc02x_hci_1v1_16.4_56" and
the VID+PID also)
Well doing this reduced the range of my device to 1m, my bluetooth mouse
that sits on the side of the laptop has a realy bad reception. So I got an
identical laptop from work and got the firmware from it to put in mine, but
I can't do the upgrade I always get an error at the middle of the upgrade
about the device not being ready... This happens at byte 2046 if I try with
my backup but with genericcsr.dfu I get this error at byte ~ 613000.

Does anyone have a hint on how to resolve this?
I've tried this with dfu update from marcel and also with the widcomm tools
in windows...

Thanks!
