5.1 version for MOD??? Sorry. I do not understand.

Edision os mio/mini 4k have the same updates you have. The same image on the feeds...etc. The Mini should load the 5.1 test image in Flash image first and then update it online.

Currently supporting in TNAP5.1:
Ustym4kPro
SF8008 & SF8008 Supreme
Edision 4K - MIO,MIO+, & Mini

(Some others are supported but not listed.)
