You Should now be in 3.56 v1

This does not Let you downgrade to 3.55, but shows us that it is possible to DOWNGRADE on 3.56

I take no credit in this.

You can just use the 3.55 to 3.56 spoof.

v1 had a Custom HDD bug and was fixed with v2

which do you recommend? v1 or v2?

sooo is that good for me

If you upgraded your harddrive while having 3.56 v1..then yeah i guess

Really this downgrade is useless but does show a possibility of a downgrade in 3.56, It's a start.

useless really no point to post again :/

not really its the same dam fw so it proves nothing its the same hv and lv2 version with same rootkey so why wouldnt it work?

ok im on v1
