how to enable usb debugging from computer

[aus9]

Ok there are a few ways of resolving it
---each with their own merits

1) I need you to find some way of pushing middle buttons or long pressing and getting into system settings......if you can.......then
b) go into security and tick the box to allow installs from unknown sources
c) then tell me if you can get into your file manager
d) I can then upload an APK file which you can download and put on your sdcard, manually thru your PC....reboot phone with sdcard go into file manager and install the launcher APK file

2) use Windows and flashtools to flash the Officail ROM

I note you already tried this?
I don't use Windows so can't help, if you choose this method post to one of the tutorials for flashtools here at CPA asking for help

3) Do you know how to get into factory reset mode for your phone?

For some devices it is from the power off state
press power and vol down
for some
press power and home key (camera key) and vol down

b) then we will get you to do a factory reset
