 +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. The bootloader's FTP is not immediately 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. 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.
