I am following the official instructions on how to upgrade to the most recent LineageOS version. Running
adb reboot sideload works. However, TWRP shows me 3x3 matrix to enter an access pattern in order to ‘decrypt data’. I can’t remember setting such a pattern. Trying my standard pattern does not work either.
When I enter
adb sideload /path/to_lineage.zip, I get the following:
adb: sideload connection failed: closed
adb: trying pre-KitKat sideload method…
adb: pre-KitKat sideload connection failed: closed
Has someone else faced this problem?
