Reflashing the Fon

Recommended Posts

If you were like me and the Ap51 screwed up during the flash, I found a handy guide on how to flash the fon back to it's original (or close to it) at dd-wrt.com. note yat you have to set up a TFTP server to do it. Links provided at the end of the post


"Reflashing LaFonera original firmware

1. Download the firmware:

* Download and unzip a pre-converted zip file:

7.1.1 version (Enable-SSH hole is OPEN in this version): Link

7.1.2 versions (Enable-SSH hole has been patched in this version): Link

* If you want the firmware directly from FON, download it here: Fon.com (Direct link) then follow these steps to convert it to usable files:

1. Remove the first 520 bytes of the downloaded file.

o On Linux, Mac OS X (or other *nixes): tail --bytes +520 fonera_0.7.1.3.fon > fonera_0.7.1.3.tar.gz

o Windows: Use the mirrored zip files which are already converted.

2. Change the extension of the resulting file to .tar.gz and untar it.

2. You need 2 files from the steps above, kernel.lzma and rootfs.squashfs. Put these in your TFTP server root directory. If you don't have a TFTP server, go back the beginning of this document and set one up.

3. Connect to the RedBoot prompt and type in the following commands:

ip_address -l -h

fis init

load -r -v -b 0x80040450 rootfs.squashfs

fis create -b 0x80040450 -f 0xA8030000 -l 0x00700000 -e 0x00000000 rootfs

load -r -b %{FREEMEMLO} kernel.lzma

fis create -r 0x80041000 -e 0x80041000 vmlinux.bin.l7

fis load -l vmlinux.bin.l7


or with Fonera 2200

ip_address -l -h

load -r -b %{FREEMEMLO} kernel.lzma

fis init

fis create -e 0x80041000 -r 0x80041000 vmlinux.bin.l7

fis free

load -r -b %{FREEMEMLO} rootfs.squashfs

fis create -l 0x730000 rootfs


Reboot the FON and you're done."
