Running a 640 on Slowring Windows 10.
Decided to try Fastring and did a master reset and now the phone is on cogs with
being displayed.
Have done the power/volume down button, lighting bolt setting and volume up/down/power reset and the recovery tool will not find my phone. Laptop knows the phone is plugged in as it makes a "dingdong" noise but an error come sup saying it cant download its software.
I have installed two variants (and re-installed) of the recovery tool. Even selecting "my phone was not detected" does nothing.
Trawling Google I found a thread from early this year saying the 640 cannot role back.
Help
