I wanted to try out a custom ROM, so I unlocked the bootloader of my Xiaomi Mi 11 Lite 5G NE phone and installed Orange Fox Recovery successfully. Since I somehow uninstalled MIUI in the process of installing Orange Fox, I downloaded a .zip file containing a custom ROM for my device (it's called Cherish OS, but that shouldn't be the problem here). Since I wiped the whole internal storage of my phone, I used the
adb push command to get the according file onto my phone. After installing the .zip file using Orange Fox, I pressed "reboot". However, my phone just shut down and did not reboot as it was supposed to do.
I tried holding down the power button for at least 10 seconds to get it to boot, however the screen remained completely black. Even pressing the volume down and power button did not help, the same with the power up and power buttons. Whatever I tried, the screen remained black (no boot logo, etc).
I then charged up my phone, but that did not solve the issue either (before installation it had 47%, so I doubt that the battery died during installation as it's a brand new phone).
One thing to notice is that my Windows PC makes a sound when I plug my phone into my computer as if I have plugged in a hard drive or something. But I can't get it to show up in the file explorer or with
fastboot devices. So clearly something happens when I turn on my phone, but the screen remains off.
I really hope you can help me to bring my (brand new) phone back to life. Thanks in advance.
P.S.: I used an amp meter to check the charging current, it's only around 60mA even though I used the official 33W charging brick.
