Yes ive formatted the SSD and follow all the instruction in xboxonehdd master but i use windows. Can i downgrade it to the previous OS? The problem started when i updated it february update..Have you formatted / prepared the new SSD for use in the Xbox One? https://github.com/Juvenal1/xboxonehdd
Ive tried installing the new OS but with no luck its still stopping in 1%. What will i do with my xbox?You can't downgrade, ensure you are using the current newest public system update: Xbox One System Update 10.0.19041.4162 Download (August 2020 Update)
Nope the old drive doesn't work.. My old drive was 1TB and i changed it to 480GB SSD is it possible that my xbox is still detecting my old HD(Bind to the xbox)?Does the old hard drive still work? if so you could try cloning the contents to the new drive: https://www.tweaktown.com/guides/7969/quick-guide-upgrading-xbox-one-internal-storage/index.html
