1 - Do I just replace the partition names in the avbtool make_vbmeta_image command to match the names of my partitions?
2 - What is the command to flash the vbmeta to the device using fastboot?
3 - I have additional partitions (socko, odmko), do they need to be included in the above command? Do I have to extract ALL the public keys for each partition, therefore I can't use the generic keys provided despite them being the same for the other partitions?
Device is running Android 10.
Thanks for the help.

(25-09-2020, 03:19 AM)JamesAt15 Natureboy, were you able to sign a custom vbmeta for the iplay 20?
I recently bought an iplay 20 as well, and I have unlocked the bootloader. I would like to do the same as you were planning, so if you have any suggestions I would very much like to hear them.
