Any instruction on how to update from LineageOS for microG 14.1 to LineageOS for microG 15.1? According to their website:
it is not necessary to wipe your data, just upgrade your TWRP bootloader and flash manually the latest LineageOS for microG 15.1 zip
I downloaded the zip file but TWRP gives an error when installing:
checking for digest file…
Skipping digest check: no Digest file found
Warning: No file_context
E3004: This package is for device FP2; this device is .
Updater process ended with error: 7
Error instaling zip file '/sdcard/download/lineage 15.1-20180813-microg-FP2.zip’

am I missing something? what is “upgrade your TWRP bootloader” meaning?
