• Bought a cheap Pixel from ebay.
• Unlock bootloader.
• Install TeamWin recovery, TWRP.
  • For this I have to do a full re-flash to the factory ROM, otherwise I got stuck at reboot loop somehow. I guess the ebay seller did something to the phone.
• Root vis Magisk.
  • New way is to patch a boot.img extracted from factory ROM and then flash with TWRP.
• Install AccA to save the battery from dying.
  • Settings are from acc repo READE.md: roughtly, shutdown phone at 10%, resume charging at 43%, stop charging at 45$, max current 500mA, max voltage 3920mV.

(Tested and it works.)
