 +===== Experiences =====
 +==== Router by Zen (UK) ====
 +The following steps worked for FRITZ!Box 7530 from Zen.
 +
 +  - Set PC IP address to 192.168.178.x/24 gateway 192.168.178.1
 +  - In "Device Manager > Network Adapters > Ethernet Adapter > Advanced > Speed & Duplex" select "10 Mbit/s, half-duplex"
 +  - Start AVM recovery tool and follow instructions to get to "settings adapted for your ISP" dialog. Keep the dialog on.
 +  - Login via FTP like shown above and do ```UNSETENV provider``` but skip ```SETENV firmware_version avm```
 +  - In the AVM recovery tool, now close the dialog and exit the tool cleanly.
 +  - Run the AVM recovery tool again, but do not power cycle the Fritz!Box in between.
 +  - See the tool deleting the flash area, restoring the flash, then say "... recovered successfully!"
 +
 +Afterwards, remember to clear the settings on your ethernet port.
 +
 +=== Notes ===
 +The bootloader's FTP is not immediately available. As per above instructions, I ran the AVM tool first until it reached the 'The device contains basic settings adapted ...' state and left it like that. Then FTP was available.
 +
 +Instructions by [[https://en.avm.de/service/knowledge-base/dok/FRITZ-Box-7590/160_Restoring-the-FRITZ-OS-of-your-FRITZ-Box/|AVM themselves]] say that one error can be prevented by using only 10 Mbit/s half-duplex mode on the ethernet port. This supposedly avoids the "Could not determine the version!". I also skipped the `quote SETENV firmware_version avm` command. One of these two alternations to the procedure helped me get past the "Could not determine the version!" error.
