flash international 7270 with german firmware

[remkow]

I have an international 7270 with an ISDN line. Is it possible to flash it with the German firmware? (I would like to use the fritz!mini and the labor firmwares).
I tried the search option but only found topics for flashing international firmware into German 7270.

that should be quite easy!

first you have to tell your box that it is a german model not an international:
download the file "fritz_as_avm_newer.tar" from here: http://www.ip-phone-forum.de/showpost.php?p=971638&postcount=1057
go to the fritz!box webinterface an upload the file (do not extract) just as you would do for a new firmware, ignore any error messages, after that your box should get unresponsive
then do a recover with the german firmware, which can be found here: ftp://ftp.avm.de/fritz.box/fritzbox...ITZ.Box_Fon_WLAN_7270.04.70.recover-image.exe
after that you have an international 7270, which thinks its a german one with the german .70 firmware and you can also upload the labor versions of the firmwares
hope that works for you!

It all went well with the following remarks:

• I had to load fritz_as_annex_b_kernel_args_newer.tar as well to get my internet connection working (I have ISDN).
• I had to change the WLAN channel from auto to channel 5 to be able to connect Fritz!Mini (I don't know why).
• VOIP/SIP isn't working yet: I get the following message when entering
  FRITZ!Box verfügt momentan nicht über Zugangsdaten für eine Internetverbindung. Dereingerichtete Internettelefoniezugang ist jedoch nur nutzbar, wenn FRITZ!Box über Zugangsdaten verfügt. Geben Sie unter Internet/Zugangsdaten die erforderlichen Daten ein

That last error is strange because my internet connection is working, specifically it has the setting:

Happy to hear that it worked. Don't know why you had to patch the box to Annex B because it should have been before? I can't tell you anything about the Fritz!Mini, because I don't have one. And the last error is very strange, youu are right, but I also can't say more than that. Sorry

Don't know why you had to patch the box to Annex B because it should have been before?

ISDN = Annex B. The other way round: when you configure a 7270 with ithe nternational fw you must expressively choose Annex A or B. The same step has to be done when "telling" the box that it should work now under Annex B.

VOIP/SIP isn't working yet

Does it really not work or you only get the message? Did you activate "Expertenmodus" (Erweiterte Einstellungen > System) and then register the internet telephony service provider(s) detailed account data(s) on "Internettelefonie". Could you post a screenshot of the page "Internettelefonie" and "Internet"

I was able to fix it by editing the config file directly with FBEditor. I made the following changes:
targets {
type = pppcfg_target_internet;
name = "internet";
only_crypt_auth = no;
local {
username = "$$$$ITBPJSMESWULWL2FFQFXFDI6JXG5WUVWE4QKYRHVLGLAZBPD2EQ1J5RQQ6XMFCT66MSCQPJ65GKJKAAA";
passwd = "$$$$34MOFDYTCH1D5HLGZQ5LJAW3GJBWLQQRWMCT4ENA3UJH5GVCY2VKRA4OXSMDWBFKGPM6RBLAGUQHCAAA";

to
local {
username = "";
passwd = "";
}
in 2 places.
Everything works fine now, thanks for the help!
