did you see this:
Hello, here is link for moding Mi 4A, tehnique is same just pinout on board is different. Use pins on board from Mi 4C but u can make rest same.
Sorry, I do not know.
Hey, how to i remove the heatsink, do i need a heater gun?. And can you explain more the connection from D+ and D-, data 5V and ground connection to usb?
Heatsink is usualy fixed on with thermal pad/sticker. I usualy take long nose (needle nose) pliers and gently twist it while pooling out (more twisting than pooling, and care to not scratch board or pins) then it will come loose without damaging the thermal pad and heatsink that you reuse later. About usb soldier with wire to its position on usb female connection. https://components101.com/sites/default/files/component_pin/USB-A-Jack-Pinout.png
Add 15k resistor from d+ to gnd and 15k resistor from d- to gnd.
Since it's a wiki, you can do it yourself, you don't have to wait for someone doing it.
See Applying for OpenWrt wiki account for getting a wiki account.
So Ground -> 15k ohm resistor -> D+ and D-
from 15k ohm resistor -> wire Usb female socket
or Ground -> 15k ohm resistor -> D+ and D- -> wire usb female socket
And just pull with twisting the thermal pad or pull with circling the thermal pad?, then how do i put the thermal pad back? With glue?
U dont need 15k res to 3.3v. i think i read somewhere that one res is tied on internaly or via some other pad. U can check datasheet if you are intrested further more.
So i can use same ground to usb female too?, and for placing the thermal pad again, do i just need to put it down or need some glue?
What's the symbol meaning in middle of the connection ?
Yes same ground. That is continuity of connection representation
for the thermal pad, do i just put in again in the processor or else
Hey, pardon me you have the firmware that have the usb ehci turned on
Yes just slap it back on same position with heatsink.
And about firmware no srry i dont have i swiched to new project.
Ask @Rubrex i compiled firmware for him while i had setup for Mi 4C
Thanks, and can i use a pinset to remove the heatsink and thermalpad?
really don't know, you can try just don't pry too much that u don't damage board or pins underneath. In my experience thermal pad stay glued to heatsink in 99% of times when MCU of routers are in case.
So how do i remove it? I've already twist it but it's so strong.
