I need a power IC for MI5. Could you please advise where I can find the IC and what the price is?
Did you find it? Please reply. Thank you.
The best photos so far, very good job.
This is the first time I have seen how to remove the side button, as I need to replace it. I also need to know if it is necessary to remove the battery and the motherboard.
Any detailed help or tips are welcome
Thank you,

I want to replace the battery. I know every step, but I need help knowing exactly which screwdrivers are required.
I want to replace the battery terminals on the board. Please show me the jumper ways.
Is the main camera connector somehow related to the phone’s audio sound? After replacing the telephone receiver, my sound disappeared. I suggest that I caused bad contact with the mainboard somewhere during assembly. The headphone sound works perfectly, but the audio is gone. The speaker works perfectly on another phone. I figured out it was due to some bad contact in the area of the main camera. Beforehand, when trying to play a sound, the phone would directly restart. After pressing the button in the area of the main camera, the phone stopped restarting. But the sound is gone.
Is it repairable? Where is the mainboard’s connector to the speaker’s cable?
Thank you!
