I’ve hit the same snag as you when I tried this for the first time.
You have to go ahead and do that backup, whether you want it or not. After it’s done, the box will restart, as I remember. Then ssh again into the device and the option to remove CE from the emmc should be available (just to be sure, I’ve left the USB stick with the backup on it still plugged in).
Thanks, as you suggested I used the ugoos website method to reinstall android and started again. All working as expected now.
Thanks for the help. I ended up re-flashing with the original firmware for the am6b+ using the ugoos guide. In hindsight, I think this would have been easier! Live and learn

Thank you for what you are doing @cpm , it would be helpful if the features you are building on were included for newer processors like the S928, or at least included VS10 so Samsung owners could convert DV, that would be appreciated.
Well, with a few PRs to the main CE branch that would be easy. It’s a dev’s choice.
Hi I am new to using Coreelec and I’m not a heavy IT guy, so need a little nudge in the right direction. I just got the am6b+ yesterday set it up using the dedicated guide on here with Cpm bin too. Using most up to date nightly
All Dolby vision files were fine in playback using kodi addons (banned). Cpm DV settings are on-demand mode and display-led
Now today for some reason any movie using DV is freezing straight away on playback as soon as my LG C3 pops up the Dolby Vision logo in the top right corner and will stutter slightly along or not play at all
Any help appreciated and will give more info on request, thanks!
Maybe the issue is your source? Did you try playing a DV video from your local network or local storage?
The same source I played yesterday played completely fine, but today not just that source but tried other movie files too and same issue of freeze and stutter.
I only stream DV videos through addons
IMO not a build issue. Would bet the same DV remux played locally will not choke vs being streamed from add-ons.
Any idea why it played fine the other day but not yesterday? Again it wasn’t just one remux, multiple remux files played absolutely flawless the other day but now just struggle
I have tried smaller files and I get the same issue?
Would you recommend a fresh install and if so how do I do this as I have dual booted coreelec to the emmc via ceeemc
Thanks!
Quick question, does installing the cpm build overwrite the nightly? There’s been a ton of work done on audio sync issues which have been released in the latest nightly and I wondered if installing the cpm build would effectively remove those updates?
Go to the github and read through the build info for A10, which is included in A11.
Yeah that’s not referring to the fairly significant changes which were included in the current nightly build. I see there’s already a commit for that though so should be on the next cpm release I would imagine?
cpm’s GitHub currently says this at the top:
So it looks like he’s still working on something atm.
It’s playing 90gb files in hdr fine, it’s just when my LG C3 switches to DV that it freezes completely which it didn’t do on the first day so not an internet issue? Also same tried playing a DV file in hdr instead and it plays fine so its definitely something to do with when my tv switches to Dolby
Would you recommend a clean install and if so how do I do this as I have dual booted CoreELEC to the emmc on my am6b+
Really, didn’t he stop a few days/weeks ago?
I really don’t know what you mean but thanks for your interest and I hope it will be available soon.
Yes, it does
he more or less stopped feature development at that point (bar something critical, like sync stuff) but planned to clean up some of the latest code, before leaving.
Is it possible to further improve the BDJ menu function? It’s really bad right now
