hello everyone
I have dead redmi 4a
I think PMU is dead but I dont know how to check it
As far as I know I need to power it with 4.5V with some testpoints, but don't know which exactly. Can you help me?

 

Hi,
You need test point of redmi 4a ?

 

yes, but not these for EDL
I need other testpoints, where I can power 4V to start phone, it is completely dead

 

Please use this one to save your phone: <Bạn vui lòng đăng nhập hoặc đăng ký để xem được nội dung này!>

 

 

Is it for data saving? I dont care about data but want to repair it
I read somewhere that it is problem with power controller or charge controller and it is possible to power it through some testpins with avoiding to use power controller

 

If it's totally dead and PC can not detect its connection, eMMC changing is final solution and you need the skill of hardware reparation so as to fix it
Be careful...!

 

ok, thank you
