Downgrade iOS 11 GM to iOS 10.3.3 on iPhone, iPad or iPod touch. No Data Loss!

don't buy it does not work for what they are showing it to do. anything after 11.0.0 does not work it will not downgrade

there is no 10.3.3 option on my pc

my phone was in under warrenty by doing this is thrrre any chance of losing ittt

by doing this processs is it safe

When urs says iOS 10.3.3 and you download it, mine says iOS 11and I’m trying to freaking get off of iOS 11 this is really irritating me

Is this safe in windows?
