Sorry, I have not a recovery app. I am waiting now for DHL with microSD card, tomorow will see. Tree is correct, I hope, I have 1 giga net and 3 giga memory, file was renamed to dtb.img.I have only two choices. Normal press is sleep, long press I see menu Sleep or Restart. "Reload to LibreElec" only asks "Really" (OK or Cancel) and do nothing for me.
got the same box E-H8. I'm not able to get it rooted (really crazy) and I'm afraid the apk "Reload to LibreElec" requires the root access.
But I have finally loaded LE using micro SD card. There is reset button (little hole on the bottom). You have to remove card and disconnect from power. Then press and hold hidden button and connect power. Requested menu will appear after a while. Then you can plug in the card and select reboot to boatloader. Don't worry if you see Evolveo logo again LE logo is shown after it. Didn't try much yet with it but first look is great. The best is that frame switching (I've 1080 only) is working fine that was not the case with Kodi under Android. Have played DVD ISO and MKV with both H264 and H265.
