I would like to try the build.
However, when trying to flash the provided TWRP, this happens:
fastboot flash recovery twrp.img
Sending 'recovery' (39360 KB) OKAY [ 1.270s]
Writing 'recovery' FAILED (remote: 'size too large')
fastboot: error: Command failed
I just bought the phone and the previous owner installed LOS 18.
I don't quite understand why the provided recovery wouldn't fit.
Is the size of the recovery partition — if that's the correct term — variable?
If so, how to resize it so that the provided TWRP fits?
