Im trying to get my phone into the mode whereby i can use sp flash tool.
in order to do that i need to install MT65XX Preloader drivers. i got them
but when i remove battery from phone and plug it in via USB to my Laptop, its connects for a second, preloader install pops up and then before i get a chance to install the driver in device manager, the phone disconnects on the USB. everytime this happens..
any thoughts?
No luck, device just disconnects when its attempts to install preloader driver....
I think that’s normal, and always be like that, as long as driver has installed to your laptop, it will work, you must click download or firmware upgrade first on your laptop then plug your usb to phone, upgrading will automatically start....
Good luck

it is normal.
the phone without power/battery connect to computer, the power is all from computer. power is not continuosly supply to the phone, that is why u only see the device for seconds. try to use shorter cable n good quality cable. u might see the difference
edit.
it does not matter. u still can flash the rom.u hit the download button first. only then u connect the phone to the computer. then the power will continuosly supplied to the phone
