[OT] struggles installing builds

[Mikus Grinbergs]

FYI - finally managed to put an update.1 build on my G1G1.  For my 
system, the solution was using an USB stick, instead of a SD card, 
to load in the build image.  [With SD cards, the process would erase 
the nand contents, but would then get stuck when trying to write.] 
The strange part was that following the wiki Activated_Upgrade 
process (e.g., for 653) worked with SD, but following the wiki 
Autoreinstallation process (e.g., for 657) kept failing with SD. 
['Olpc-update' seems not meant for my situation -- I don't have mesh 
or wifi, but only wired (which then goes through a proxy).]

I prefer to look at documentation to show me "what is possible".  To 
me (when faced with the 'ok' prompt) the Open Firmware information 
mentioned in the wiki seemed a poor guide;  even 'help' was limited 
in its coverage.  [For instance:  is it readable someplace that the 
OFW device identifier syntax is 'sd:' for accessing the "SD card" ?]

The descriptions of the 'Cheat Codes' are scattered and confusing. 
[For instance:  does button 'X' (at boot) override the presence of 
an os_image (etc.) on /boot of an USB device ?]  There were even 
boots when I needed one hand to hold down one button, a second hand 
to hold down another button, and a third hand to press 'power on'.
