New tools are now available for Fonera+ 
These tools are adapted from AP51-Easyflash from Freifunk.
A big thanks to Sven-Ola for giving us access to the sources, that allow us
to adapt for Fonera+.
Thanks to skynetbbs for writing the doc.
Just follow the instructions on this page :
http://www.fonboard.nl/wiki/HowTo_Foneraplus_unlocking2
You just need libcap, change the public-FON SSID to FON_UNLOCK, shut down
your fonera+, launch the tool (use the good ethernet interface name as
parameter i.e. eth0 or eth1) , power-on your Fonera+, and let's go.
No reflashing for unlock, it's quick and safe.
Others commands are available for FON public SSID:
FON_REINIT : will erase JFFS and restore your Fonera+ with default factory
settings
FON_DIAG : will install diagnostic page on Advanced menu FON_REGISTER : will
change the icon on status page after a reinit from "unregistered" to "Your
fonera is successfully registered"
You can also restore a full FON-firmware using 2201-full-restore app all-in-one file (unlock is not included).
Restore firmware:
sudo ./2201-full-restore eth1 image(size 0x00230004) + loader-image2(0x00150000) + config sums up to 0x003a0000 bytes Peer MAC: 00:18:84:a0:xx:xx Peer IP : 192.168.1.1 Your MAC: 00:ba:be:ca:ff:ee Your IP : 192.168.1.0 Setting IP address...
