I have an ATIV S with OS 14157 and 24184.108.40.206 f/w. Can I just modify the registry to get GDR2? And then can I change the registry back to what it was and keep the GDR2 or if I hard reset it will take me back to GDR1? One last thing, any problem with not having a firmware with GDR2? Or GDR1's firmware works fine with GDR2?
So you are saying there is no risk in changing the registry, right?
change of registry is only temporary, until to first hard reset
is pretty safe but I can't tell is no risk, I don't know what is happens if you change wrong registry, another registry than are specified in guide or with a different value than specified in guide
gahbmwm: I have Ativ S, of course. Last FW ...15.3.2 and 8.1....341 WP (ATO). With PfD and Insider apps. It offered me directly W10.
not necessary, you can hard reset your phone and then follow the guideSo only to be sure, I have to downgrade to 8.0 CMJ1 ATO. After pass through all upgrades. When finished I have to run Insider app and receive 8.1.2, after do hard reset to prevent upgrade to 10. OK?
