Hi!

I would appreciate some help on this matter. The issue I have is that I have to use the Fritz with a cable modem and when I set the configuration on Internet access via LAN with PPPoE on reboot I cannot connect wireless or USB or whatsoever...

I tried to load fritz_as_avm_newer.tar and on reboot tried to recover the 8.04.34... doesnt work because it says incompatible hardware.

I entered with ftp adam2 (telent doesnt work) and also change annex A into annex B with SETENV, same result using recovery 8.0.34.

I changed kernel SETENV into annex=B... same result. After 4 hours playing with it, dont know what to do anymore. Please help me!

1. Welcome, adrians

2. In brief: you must change "firmware_version" from "avme" to "avm" and run (do not allow the box to reboot before BOTH steps are done!!) German RECOVER 08.04.34. [POST=1323573]Here[/POST] you find (unfortunately in German only) how this can be done using ftp.
The alternative method is to use "ruKernelTool" from "skyteddy". Search for it in this forum. Many users say this is the easier way for beginners and I would agree on this even if personally I do always use ftp.

Thanks for your help! As it didnt work over ftp adam2, I tried the ruKernelTool. It doesnt work either. I can put the "old" Annex A AVME firmware back but not the AVM 04.34. I will copy the log here

Where is the problem? The box gets stuck in booting or loading kernel somewhere. I can always put the 04.49 AVME image and it works. Should I try to change with adam2 the HW-Revision? Is 66 for Annex A and 64 for Annex B?

Have a look [THREAD=169769]here[/THREAD]: Annex A = 66 -- Annex B = 61

Fear you might have to do things "manually" using ftp as suggested in #2.

ftp commands

quote SETENV HWRevision 61
quote SETENV firmware_version avm
quote SETENV firmware_info 08.04.34
quote SETENV annex B
quote SETENV kernel_args A

close ftp "bye" now run IMMEDIATELY (do not allow the box to reboot, do not plug off even if you are asked to do so) German recover 04.34

Interesting... I did put all the settings and yes, I was able to flash the 8.04.34! However, now the problem is that fritz doesnt boot! I ftp again and check the settings. Believe it or not they are reverted back :

230 User adam2 successfully logged in
ftp> quote GETENV HWRevision
HWRevision 66

200 GETENV command successful
ftp> quote GETENV firmware_version
firmware_version avm

200 GETENV command successful
ftp> quote GETENV firmware_info
firmware_info 10.04.34

200 GETENV command successful
ftp> quote GETENV annex
annex A

200 GETENV command successful
ftp> quote GETENV kernel_args
kernel_args A

200 GETENV command successful

Do not understand... How I should resolve this? Made some progress, I can flash now, but settings are reverted and the image can not start.

This is normal - HWR and Annex changes through ftp are only temporary until next reboot - this is the reason why you must NOT reboot or power off between ftp settings and recover.

Made some progress, I can flash now, but settings are reverted and the image can not start.
No - you made the big step to 08.04.34 (you wrote 10.04.34 - think it's your writing mistake only) and avm. To look for a final solution: your red is annex A or annex B? If it is B you should first change parameter "kernel_args" to B. If after that box still does not connect have to look into other parameters.

EDIT: Basic problem is that the latest english fw before 04.49 was 04.26 (which is available also as recover). AVM changed to newer Linux kernel at fw 04.30 (concerning ALL boxes) with a different layout of the flash memory. To go back to 04.26 would require a downgrade to the older kernel and flash memory layout which is difficult and risky but possible and described in this forum.

04.49 unfortunately got the bug from which you are suffering now: no internet over lan possible.

Therefore after upgrading an fbf and an fbfw to 04.49 I did with both boxes just what I recommended to you: go back to 04.34 avm substituting additionally the "native" B driver of that fw by the A driver extracted from English A-fw 04.26.

Only but SIGNIFICANT difference between your box and mine: my boxes were/are genuine B boxes - yours is -as I understand- "born" as A box.

Hmmm... Many thanks again for your support.

Well, I do not reboot, but after the recovery process, which goes fine, the modem reboots and the old settings are back. And I'm not mistaken it is not 08.04.34 it changes to 10.04.34 ?! It is Annex A austrian modem.

Another interesting thing: just out of curiosity I have made again adam2 changes as you advised (100 times already) and recovered with the german version of 08.04.49. Believe or not, the fritz box booted! And I was able to go on the webinterface. Now, I rebooted and check the settings with adam2: settings were all reverted Annex A, HW 66 etc but it works and it is in german... strane isnt it?

There are really some strange aspects: fw 10..? what box is that for? And how can the box get such an fw starting with 10 if you only recover with 08? ALL fw on avm server for fbfw start with 08 - no exception - I checked them all (deutsch --- deutsch-a-ch ---english -- "normal" fw and "recover").

If you say "it works" - what does that mean? works fine for you - or only "works" but NOT on "internet over lan"?

EDIT: FW 10..... is FRITZBOX SL Strange in this case that box "says" it is HWRevision 66 - which is FBFWLan.

In the ancient times of fritzboxes - with fw lower than 04.15- many changes of many parameters were possible. I feel that your box has received a lot of modding since it was produced!

Okay... lets recap here:
Box runs 8.04.49 english (FRITZ.Box_Fon_WLAN.AnnexA.en.08.04.49.image) and it is a FB Fon WLAN

I have also 2 additional images, (1)fritz.box_fon_wlan.08.04.34.image and(2) FRITZ.Box_Fon_WLAN.AnnexA.en.08.04.49.image and a tool fritz.box_fon_wlan.04.34.recover-image.exe

1. I use adam2 new settings, bye ftp and directly launch fritz.box_fon_wlan.04.34.recover-image.exe. The tool works, meaning I can flash the box w/o errors. In the end, box restarts automatically, but it doesnt load (goes in the cycle reboot)
I connect to the box again with adam2 and checking the settings I see they are changed to the old/initial values. In addition this firmware variable displays 10.04.34

2. Make again changes to the settings via adam2 and this time I use ruKernelTool to push FRITZ.Box_Fon_WLAN.AnnexA.en.08.04.49.image (kernel) into the box. Well this time, after flash completes, the box reboots and it load the image - i can access the box via webinterface.

My point here is that I can flash and the box runs both versions of 8.04.49, german and english. It doesnt help me of course, because I need the Internet over LAN with PPPoE.

do you think my recovery exe is faulty? - cannot be, is downloaded from fritz ftp site... What about using this kdslmod.ko from another image of eumex? to patch my 8.04.49 english? Is this an option for me? Is there already a pacthed image 8.0.49 english with kdslmod.ko that I can use - I have no linux machine!

okay...dont know if it was smart but I changed the bootloader cat mtd2.bin > /dev/mtdblock3

I have downloaded 08.04.26 recovery file annex a avme, it detects the box but says incompatible firmware. I assume is because of the firmware_version or firmware_info


I'm back with adam2 and unfortunatley cannot SETENV (setenv failed) and I see that I left the firmware on avm. Any advise?
