I point you to this thread: http://www.internettablettalk.com/fo...ad.php?t=17665

If you have a friend at a service shop, go for it

I will post what I know and what could be theory.

Wlan values are set in initfs time:
echo "Pushing the WLAN tuned values"
/usr/bin/wlan-cal

(From /mnt/initfs/linuxrc)

If you check the syslog, you can see it being done.

Now, initfs is one of the first things to be "inited" (after bootloaders afaik), so it must get those values from somewhere. Because Phoenix and flasher-3.0 seem to write to the same place, I'm willing to guess it is the “config” flash partition at /dev/mtd1ro which would be available to the initfs. No idea on how to edit it but I would bet the values are in there.
