Having a README is helpful indeed. :-)

Some comments on this README file:

It'd be helpful to have the actual device usage there as well, as used
on <http://shop.goldelico.com/wiki.php?page=GTA04%20Complete>:
|    - GTA04     = Letux 2804 (smartphone)
|    - GTA04b2   = Letux 3704 (PDA)
|    - GTA04b3   = Letux 7004 (tablet)


(2)
Item "5." is used twice. ;-)

This must be either "bunzip2 -c" or "bzcat".
Otherwise it'll just uncompress the file without writing to the SD card.


(4) SD card size
The latest 2804 SD card image (20140728-gta04.dd.bz2) size is 1056964608
bytes. Despite being less than 1 GB, it might (like in my case) *not*
fit onto a regular 1 GB SD card!
Users should consult lsblk etc. before.

(5) Bootloader flashing

This is a bit unclear. AFAICT this is meant to mean that the as soon as
the battery is inserted, the Boot loader will be flashed? (This was the
only time I saw a complety red screen, and only for a very short time.)

After this step, at least the nice AUX-pressed touch menu is back.
And, FWIW, I *one time* saw the items "Blink" (color change of start
button) and "Button LED" (turn green AUX led on) do something, although
they don't do anymore now. :-/
The item "NAND" is, for obvious reasons, still failing (see below).


(6) Flashing to NAND
> 1. Boot the device (again) from this SD card and connect through Ethernet over USB

"This" is a bit unclear; I suppose "this" shall refer to the newly
created one, not the one mentioned in (2.) under Bootloader flashing.
Also, booting from this card just shows a completely white screen for
me, which should be mentioned as well (if that is intended behaviour
which I guess it is not).

Doesn't work. *sigh*

I also tried running ./camera-demo to test the camera, but that also
failed miserably (due to several failed install of packets it needs, eg.
