I wanted to try out a custom rom, so I unlocked the bootloader of my 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 (its 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 Xiaomi Mi 11 Lite 5G NE. 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 volume down and power button did not help, the same with power up and power button. Whatever I tried, the screen remained black (no bootlogo 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 its 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 has plugged in a harddrive 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 (brandnew) phone back to life!
Thanks in advance.
P.S.: I used an ampmeter to check the charging current, its only around 60mA even though I used the official 33W charging brick.
