I fixed it by updating my /e/OS from 1.x to 2.0
0 - Backup data
I simply export contacts, messenger chats etc “locally” to my phone and run adb pull /storage/* <targetpath> and note down passwords, if required, to a sheet of paper
1 - fastboot
2 - Download the latest stable build (for FP3+ follow this link: https://images.ecloud.global/stable/FP3/)
3 - unzip the just downloaded archive
– IF YOU’RE ROOTED AND WANT TO KEEP IT THAT WAY –
3.1 - open the install script flash_FP3_factory.sh, search for oem lock and just remove that line
4 - chmod +x flash_FP3_factory.sh and run it
– IF YOU WANT TO KEEP YOUR DATA –
4.1 - just hit enter when asked if data should be wiped (otherwise follow instructions to wipe data)
5 - Wait till done & reboot
(6 - Burn the sheet of paper with the passwords as soon as you don’t need it anymore)
Even though I successfully updated without any data loss and kept root that way, ALWAYS backup your data BEFORE flashing anything
