Help stuck after editing build.prop

[Oskars]

Hello friends! I'm stuck boot up icon. I cant find firmware. Maybe its other ways to get my tablet back to work? My tablet - Goclever quantum 700n Lite .

I take it you don't have a custom recovery installed and/or the ability to install/launch one (with a possible restorable Nandroid backup)? That would get you the ability to adb into your device to at least re-edit the build.prop file back to it's original state.

Barring that, even if you had previously turned USB debugging on, a wonky build.prop edit induced boot loop is not likely to have gotten to the point of launching/enabling the adb daemon for you to try to fix.

Not many (any?) options that I can see or think of, unfortunately .
