JSN-L21 9.1.0.266(c432e1r1p1)


Hello support,
pls can you in detail explain, how to downgrade or prepare specially this model for frp bypass?
I'm not newbie, but by my meaning, https://sigmakey.com/en/supportedfea...?phone_id=2634 information is generally only, not specific and risky at that case.

Thank you, BR
