Alioth phone

I have unlocked bootloader, flashed miui 14.0.7.0 (in setting it had still shown 14.09.0, but I read its a miui bug), flashed "additional partitions", lineage recovery, formatted storage, "successfully verified" boot.img using python and tried to install it with "adb sideload lineage-20.0-20230701-microG-alioth.zip". Progress percent goes up to 47% and stops. Lineage recovery asks "Signature verification failed Install anyway?". I click yes. Terminal on bottom of recovery writes 5 errors and "install completed with status 1" and in next line "installation aborted". When I click "reboot system now", recovery asks "WARNING: Previous installation has failed. Your device may fail to boot if you reboot now. Confirm reboot?". I click yes.

Phone shows poco and miui boot logos, plays boot sound and screen goes black. My pc (win10) detects phone and opens empty file of it in file explorer. When I press screen on/off button it plays sound of going to sleep mode. Nothing else. Then I press power and volume up button and it goes to back to lineage recovery.

How to fix this?

For Wifi assume good (not ideal) signal and for Ethernet typical 1gbps 15m cable

Firefox (July 10th version) When I type email and password and click "Login" button I get "Logged in l" notification and it returns back to post. Except Im not logged in.

Logging works with Opera and Jerboa app fine.

I changed password, but it still doesnt work
