Downgrade FBF 7170 from 29.04.29 to 29.04.01

[Snikethopy]

Hi,

Need some guidance, please. I upgraded my fbf7170 annexB with the last firm 29.04.29. I need to switch it to annexA now.

From what I read on the foro, I better have a firm version 29.04.01

I tryed the Downgrade.tar script, without success.

Worst of all, the AVM ftp server does not have this old version.

So if someone could help me out here, pleaz.

Last info; my fbf7170 is labelled from 1und1.

Hello,

Thanks to this forum I have now the needed firmware.
BUT....

When I try to uploaded the firm 29.04.01, my FBF7170 tell me that the firmware is not valide, and I can choose whether to Cancel (recommended) or the GoAhead.

When I tryed to pursuit the process, the box just rebooted.
Also tryed with 29.04.21 and 25.

Does someone have an idea how to perform this downgrade ?

For info, I have a FBF 7170 2+, branded "1und1" ArtikelNr 2000 2330

Thanks in advance...
