I want to ask you the followings before doing hard reset:
1- Do you advise me?
2- After factory reset, on which OS I will be? the 10586.495 that I was on before installing Redstone,
or it will take me to win 8.0 or stay on Redstone ?
3- Is there any risk to go back to win 8 and failed to upgrade to win 10 either on insider after releasing the windows 10 Redstone preview as they mentioned in the latest news ?
4- Can I unlock Boot loader via WPinternal from my current Redstone Build ?
Please reply back before any further step
Thank you,

But for q no 2, factory reset will keep the same OS, it won't down grade your phone
