Me?  It will void your warranty.  Oh, wait.  Already out of warranty.

Yes, the XO-1.5 internal storage is microSD card in a cage, accessible
after disassembly of back panel.

Test the microSD card in the SD slot first; to make sure firmware can
operate with it.  No point if that won't work.

http://wiki.laptop.org/images/f/f0/XO_1.5_B1_Annotated_Motherboard.png

In that image, the cage is in locked position.  Record what you find,
especially the length of the card exposed to the right of the shiny
metal.

Failing to lock it afterwards will cause unpredictable behaviour;
thermal cycles and vibration may set the card adrift in the case.

To unlock, push the cage to the right with a force parallel to the
board.

To open, lift the left edge.

Remove and replace the card.  (Continue to use ESD precautions on
these microSD cards, they are vulnerable).

Lower the left edge then push the cage to the left, with a force
parallel to the board, until (a) you have felt a click, and (b) you
see the same exposed width of the card.

Then with the system still disassembled, try an fs-update, and then
try booting at least ten times.

Yes, the filesystem should resize on first boot.  13.2.5 will quickly
resize to 16 GB, but beyond that it will take quite some time.  Use
the tick (check) key on first boot and watch the storage indicator so
you can tell what it is doing.
