Ambit vmng 300 + 300 v2

[Canis-Major]

I guess that depends on what I flash, cause so far, 3 full 8mb dump's from different site's are well fecked.. ie not working.. just goin through what I got before I desolder wires, but tell me, if I have an image1 and image2 from someone, which tabs do they go into, like, say I want sbh alpha 1.1 on this, done the bootloader, where do I chuck alpha, env1 or 2, or ubfi1 or 2?
