Hi, New to the forum and this question may have already been asked, but after days of trial and error trying different stock roms, ive concluded my box wont work on Lollipop, i just get an error installing Abduls android 5 system rom, Im limited to 4gb on this box, and ive seen people talk about booting Librelec or Linux from EXT sd or USB, i wondered, is it at all possible to boot my box from USB oe SD Card, rather than from the internal system, to save memory?, or if this is not possible, is there a way to install or move my apps to ext usb and run them from there rather than been installed directly to the box?. Ive also been looking to see if i can find some custom roms, but there only seems to be stock available other than Abduls lollipop, i read there was an Abdul 442, but i cant find that anywhere online. Thanks in advance.
