Since there is no formal forum yet for the V4 Release I figured this is the best place to post.
Updated from 3.0.4 to V4 on an MED500X (non D+), first time no-go (sits at the M8 logo) so updated with the bootloader patch and then re-flashed and now all is well.
Only one issue so far, watching an avi last night and paused/un-paused several times to attend to other things (maybe 5 times), then reversed about a min in the video to catch up where I left off, video on the screen went "green" (strange olive green) and audio continued, stopping the video did not solve the issue had to shut the M8 down (remote worked fine to turn it off) and reboot, video played fine after that.
Not a huge deal but never seen this behavior on 3.0.4 and hoping it was just a glitch.
