So I have a replacement D3 arriving here on Tuesday so I thought I would dig around this one a bit being that it is messing up anyway. Found a few things that should be helpful to us hopefully shortly....or now would be awesome.
Anyway...all of these started with battery out....hold the key first then insert battery and hit power...all the while holding the key.
Here we go
Volume down = AP Fastboot
Both volume keys = Boot menu with options for
- AP fast
- RP SBF Flash
- RP only
- AP RP USB Bypass
- BP Tools
in this menu only volume down is used to navigate and volume up selects
Right navigation arrow (keyboard) = RP SBF Flash mode....same as in previous menu but takes you directly to it
Up navigation arrow (keyboard) = RP Fastboot Flash Mode
M = Same as both volume down and volume up
B = Vendor flash mode
F = fastboot flash mode
I am sure there are more and I will mess with it more tomorrow and post what I find.
