Unfortunately when it's applied LE firmware over a non-LE all keyboard mapping changes, including those three buttons. VOLUME + / - and MENU. That's why MENU / USB plug doesn't work.
Solution: take thing with calm and without any hurry... open case carefully... by nails... don't use any tool in order to not damage it... be patient... you have spent lots of time dealing with your error... there is no need to do thing faster now... this is a safe procedure and always work.
When opened... search for flash memory it should be the longest chip (here you have VX858, VX858LE and VX878 opened
VX858 VX858LE VX878 yours must look like the upper player.
There are 3 big chips: the square one is Rockhip (do not touch it!!) and two rectangular one with pins on long border which is BIOS chip (Hynix) and one that has the chip in the narrow border which is flash memory (Samsung)... you'll work on this chip!!. There should be also a small square one which is Wolfson chip. Here the picture of your player
.
You must have an
iron clip to do the short-circuit procedure.
With the player switched ON and USB cable plugged IN... and PC loudspeaker ON to listen the sound signal... run softly but firmly the round border of the clip along the pins of flash memory Samsung. It will make the screen go on and OFF... that's normal... try both sides of Samsung chip... until you hear the sound signal of the PC announcing that there is a connection. It will show "rockusb" device on try icon
Install firmware for VX858 non LE, any version... later you can try other non LE versions.
Good luck!!
