  2. Hi !
    My MX4 is stuck in bootloop. I want access to the fastboot mode but the bootloop consume battery faster than it charge, even with 2A charger and good usb cable. I removed battery in order to charge it manually only with cable, but I didn’t find the + and the – with multimeter (to small connector ?)
    What can I do to charge it succesfull ? If I charge battery via usb without the middle frame on it it don’t charge. So can I dissassemble all the phone and assemble it without the screen to reduce battery consuption ? Or can I weld 2 usb cables together in order to charge with 2 charger at the same time ?
    Thank you in advance and sorry for my bad english

  3. the speaker doesn’t work well, it works only with the earphones. What is the part to substitute?the speaker control chip??is it easy?

  4. Hi David,
    I just need your help. My MX4 is a defective batch and comes with touch screen issues. I have this 1cm line right in the middle that does not respond at all and makes cellphone act crazy. Is there any solution? i can’t simply replace the digiitizer right? Guess will need to sell the cellphone just like it is. I could buy a lcd+digitizer but i will probably end up with some shitty screen that will break anytime soon. Do you can tell me where i can buy a OEM screen? I really don’t understand why companies refuse to sell OEM parts.

    Cheers,

    Thanks
