First of all sorry because i don't speak German, only Portuguese and English...
I need help (Someone recommended me Mr. Feadi !!) because i have a Fritz!box 7140 Annex B version AOL in German, and i tried to change it to English last version and Annex A, in order to work here in Portugal.
After read some "milions" of threads and topics, i followed this one:
So I won't take any responsibility for what you are doing.
First you have to double check where exactly the bootloader in your fritz is located. Therefore do the following:
Code: [Download] [Nascondi] [Select]
Code: [Download] [Mostra]
~ $ cat /proc/mtd
dev: size erasesize name
mtd0: 00800000 00010000 "phys_mapped_flash"
mtd1: 006ccb00 00010000 "filesystem"
mtd2: 00770000 00010000 "kernel"
mtd3: 00010000 00010000 "bootloader"
mtd4: 00040000 00010000 "tffs (1)"
mtd5: 00040000 00010000 "tffs (2)"
mtd6: 00200000 00010000 "jffs2"
mtd7: 00570000 00010000 "Kernel without jffs2"
As you see the bootloader is actually located on the mtd3 block (but you have to try this command on your machine. It may be on a different location). Now you can overwrite it with your own bootloader.
So, assuming the bootloader is on the mtd3 block, place your bootloader in the tftp server default directory, rename it mtd3.bin, start your tftp server (I recommend Solarwinds) and type the following:
tftp -g -l /var/mtd3.bin -r mtd3.bin <ip as appears on the tftp server window>
With this command you have transfered the bootloader in a temporary directory. Please double check it is actually there:
$ cd /var
/var $ ls -la

You can see the mtd3.bin (whose size is 65536) is actually there. Now you can enter the potentially dangerous command.
Again, you do it at your own risk So keep your fingers crossed and enter:
cat /var/mtd.3.bin > /dev/mtdblock3
It will take a couple of seconds. Now you can reboot and hope that everything went fine.
The problem is that after that i got no access to the Fritz, neither by Ftp nor by Telnet.
I also tried to use a recover image, but it just couldn't find my Fritz.
By the way, the ip on the Laptop used in all this process was always the 192.168.178.23, and now is 169.254.194.20, but if i run a ipconfig /all, i can't see the Fritz.
Also i have never got again the Wan light on. Now the only light i see is the Power one, and is always blinking.
Someone can HELP me ???
Thanks, Crake.
