I don't want to make big promises but I can probably build and test community WP1 and MX2 images until the drop of amcodec in LE10 or at least until the revert of the commit is the only change needed to make it work.
Once we bump to mainline kernels and clean up all the old driver packages things will break. Until then most of the 3.10 dependencies are shared with the 3.14 images so it should be a simple revert.
Are you writing the LE image directly to the USB stick, or cloning an existing SD card install? .. and which LE version?
Run "touch /storage/.config/safemode.disable" and it won't be invoked, but there's some underlying problem. Add-ons are the biggest culprit.
Stop Kodi, rename the various .kodi folders out of the way and restart Kodi. Now stop/move/restart and move bits of config back until you either end up with a working system or find the thing that breaks it. It's the kind of issue that doesn't have an easy button.
Please report to the NextPVR add-on developer(s) via the Kodi forums. We're just building their code.
*banned* is a pirate app. You are in the wrong forum. Bye.
Try using a different writer app (e.g. rufus or win32diskimager). If that (probably) makes no difference, try using a smaller USB.
We're not aware of any DB upgrade bugs but if you want to play safe .. backup the DB and the 8.2.5 config before updating.
Generic (is the only image) and 9.0.0 is the best/latest/advised version.
Use the docker templates in our git repo, clone the repo, read the wiki section on self-building, checkout the allwinner branch, build.
One of the first things CE did was drop support for 3.10 kernel devices like the WeTek Core, so that's not a valid recommendation.
Piracy add-on's are self-inflicted pain. No further support will be provided until you provide a debug log showing a clean system.
I hope you like OOM lockups and restarts when navigating around the GUI. Do I need to describe things further? 
see Can I add WiFi config to SD card pre-install? (headless setup) but this will require you to mount an EXT4 partition from another Linux install.
BR = Blu-Ray discs, which are mostly encrypted but with a completely different kind (AACS) from DVD's (CSS). Encrypted DVD's haven't been an issue to play since the seven lines of DeCSS code were first published in 1999 (and used widely since 2000/2001).
