I used SEUS to update my W810i but the bluetooth functions are poor with my Car Radio after the update. So now I want to rollback/downgrade the firmware. Called SE and they said it's not possible, are they right? Can TMS perform this rollback/downgrade?
R4DB005 is installed on the W810i right now.
How do I install the drivers for the DCU-60 cable? The phone and cable is already installed on normal use, how do I make so I can select it in the TMS program?
Thanks in advance.

go to wotanserver.com and get the information about downloading FLASH plugin.
then get xs++ (google it)
find in Forums under TUTORIALS how to connect your phone to XS++ and get readout from your phone like the following
- CID (number)
- Firmware version (example R1GB001)
- Customization (CDA number)
if you are lucky, maybe downgrading your firmware is possible. just get those 3 things and post them here.
good luck
heres how it should look like in XS++ log file
