Its your choice

If you want to backup your ta you need to downgrade

If you are not bothered, just unlock

if losing Warranty is not a problem to You then Yes, it's the quickest way. Doing this you will be unable to do a Backup TA so your DRM keys will be lost forever with the warranty.

I unlocked on 4.3 and Camera, Track ID working. X-Reality turn On and Off but I never, even when I was stock, saw any difference. So if you want unlock on 4.3 (FW .136) it's ok.
