Removing Addons27.db _should_ just re-migrate whatever database you have, hopefully succeeding second time around

First,
I deleted /storage/.kodi/Userdata/Database/Addons27.db (Userdata was missing from your description)
This did not work for me. It now boots to a black screen only. No libreelec splash or mouse pointer.

Reading on the Libreelec forums it should copy Addons26.db to Addons27.db. I do not have an Addons26.db file in my directory. It did create an Addons27.db file after deleting my zero length file.

Extra info: I first updated to 7.95.2 using the built in gui updater. 8.0 was not in the list and I figured I would just do a two step update (first to 7.95.2, then to 8.0) When 7.95.2 failed to boot properly I loaded the *.tar for 8.0 into the update folder. Therefore I am running 8.0 now, but the update failed going to 7.95.2

Any ideas?
