Flashing issues Fritz!Box 7430 - I need help!

.py = python

check AVM FRITZ!Box 7412 stuck in ramboot - #3 by nicefile

you do.
it's done by scp:ing the sysupgrade image to the routers /tmp folder, then running sysupgrade /tmp/sysupgrade.img.name, while ssh:ed to the initramfs.

did you find any info about it being flashable via TFTP ?
