I am regretting updating the firmware in my 7390 to 6.01 because it no longer supports SMB. I have followed AVM's instructions to downgrade without success.
I get this message from the router:

The update failed.
The selected file contains a firmware version which is older than the one already in use.

I see on the overview page that the unit "contains basic settings adjusted for your Internet service provider" (Snap!). Could this be what is preventing me from downgrading?

Any help would be much appreciated as it is frustrating not having SMB functionality.

Thankyou

Try the firmware file near the bottom of this post; it is a special 'downgrade' firmware which should get around your issue.

Unfortunately, 6.01 won't let you run any downgrade firmware - likely something to do with the major version of the firmware being different. The best option is to download the 05.51 recovery image from ftp://ftp.avm.de/fritz.box/fritzbox.fon_wlan_7390/x_misc/english/.

As this is an exe, you'll need to be running windows for it to work. If you want 5.22, you should be able to run the downgrade firmware after recovering the fritz.

looks like AVM may simply not allow downgrading from 6.0 to 5.0 .. major revision in their OS, i suppose it makes sense.

the lucky thing about the 6.0 versions is that you can run older DSL versions.

to get SMB back you can try recovery images, otherwise you might have to turn to the likes of frettz.

i have tried the 6.01 version and have gone back to the 5.0 firmware with no trouble .

Common sense is not as common as you think.

This is the response from AVM:

Thank you very much for the enquiry you submitted to AVM Support.

We are unaware of problems concerning the downgrade.

Did you get your FRITZ!Box from your internet service provider or did you

buy it in a store? Maybe your ISP uses specific provider settings in the

FRITZ!Box that prevent it from downgrading? You could enquire this at your

ISP.

Is there a risk this could interfere with, or even remove, the Snap! settings and give me other problems?

all snaps settings can be reconfigured.

if all else fails, you can ring snap, they will step you through atlest getting the modem online, from there they can resetup your VoIP etc.
