from Windows mobile 10 fast ring to slow/preview release ring

hi,

I am using wm10 insider fast on 14915.1000 and my 950XL's screen can't turn back on from time to time, anyway to switch back to slow and preview ring?

can the backup of this fast ring read by slow/preview ring?

this is the simplest !

to go back to older built you have to use the Windows Device Recovery Tool (WDRT), you can download it from here: https://support.microsoft.com/en-us/help/12379/windows-10-mobile-device-recovery-tool-faq
you have to connect the lumia with you pc/client via usb, and yes you can us later your export

what is import old import means ?

did you hear that, the fast ring insider's backup can't be read/imported by old build ? they are diff build number so if the backup feature of the exists fast ring build can't read by slow/preview ring, we can't do it.

I knew that.

but if Backup doesn't work between build between 14915.1000 and 10586.187 build, I can't restore using this method.
