I keep getting PMs regarding Sony Tama 5.1 SFOS release. As there is nothing private in those messages, please keep to a simple rule: ask publicly. Its a forum and reply maybe of interest to someone else too. Or maybe someone else will reply to you. Unless you need to share some private information (location related, some log with your phone number, …), keep discussion public.
Now on topic. While my daily driver is Nagara, I did work a bit on 5.1. When testing dev build it resulted in me having to reflash the phone back to 5.0 - couldn’t debug it at that time. Right now working on my apps, but hopefully will return to this port to finish the update. No promises on timing and you are always welcome to work on it too. Right now it was having screen going blank in 5.1 as soon as I tried to enter my decryption passkey on boot.
