Hi all!
Greetings from Australia!
I seem to be having problems with my K770i.. it decided to turn off suddenly last week and I couldn't turn it on again :(
The red light either turns on for a few seconds, or keeps blinking maybe 5/6 times when I try turning it on or when I plug it into the mains charger..

I'm pretty sure its not the battery problem as I've swapped another same (fresh!) battery (BST-38) but the problem still persists...
Tried hooking the K770 to XS++ / FAR + JDFlasher and SEFP / setool2lt BUT the phone does not respond to the 'C' button + connect phone combination when pressed...

Code:
23:57:07| XS++ v3.1 (Darwin) Ready !
23:57:07| Executed on Microsoft Windows Vista
23:57:18|
23:57:18| Attempting to open the interface...
23:57:18|
23:57:18| TURN OFF PHONE!
23:57:18| Hold 'C' button on phone and connect phone NOW.
23:57:18| You have 30 seconds...
23:57:18|
23:57:48| Error: Cannot open phone communication port
23:57:50| Disconnected... Unplug the phone
It only responds to the '2' key + '5' key combination in XS++ but froze when it gets to the 'Protocol Version: 3.1' prompt:
