Alioth: Install guide suggests to use old firmware

The install guide suggests to use old version of firmware, while the new OS1.xxx firmware work perfectly fine without any issues. The same firmware is suggested to be used by lineage OS too. Also the hash of recovery file doesn't match (the zip file sha256 don't match, while if you unzip file the hash of recovery.img matches with provided hash). I tried downloading the file multiple times on multiple network but issue still persists
