I have boxes Solo SE V2, Ultimo 4K, Uno 4K SE and Duo2. All other boxes are ok, but Duo2 after image update is very slow when doing enigmaboot.
Fresh flash without settings restore helps. This same happened when updating 002 -> 003 and now with update 003 -> 004.
I`m not the only Duo2 owner in Finland having this same problem
Tuners in box are 2 x TT3L10 dualtuners as T2 mode.
