[446599]

I watched your video and try to mod my miyoo mini in the same way, first time I disconnected the connection from 17pin to vcc ,but I made a fool mistake that I didn’t disconnect the connection completely,then I tried to launch the system,but when I connected the battery,the screen lit up and I can’t turn off it by using the power button,I found my mistake and tried again,this time I disconnected completely,but when I connected the battery,the green led were not on,the system time didn’t change.
Maybe I damage the chip? But the miyoo mini still works well.
Is this way fause? Here are the photo of my way,the ldo chip is me6210a33m3g.

Thank you, I come from China and my English is not very good. If I say something wrong, please forgive me.
