Ok so heres what I did after removing the battery, I pressed and hold 2+5 and connected it on my cable.
After that I put the battery in.
The wotan log then displays this
DB2010 detected
LOADER ok
FC ID: 89 7E
EROM: RED CID49
OTP: RED CID49
OTP: IMEI xxxxxxxxxxxxxx
GDFS: K700
GDFS: CDA102555/101
GDFS: Phone not recognized
Select manually if supported and press continue
So I select w810 and click continue...
then wotan client tells me that I can edit the Main and file system files
so what do I do after that?
