You were NEVER supposed to change your bootloader - never ever. In best case it's useless and unnecessary - and if things go worse, you'll brick your device, maybe you've done it already. But to get ANY clue, what your original intention was and what you REALLY did in the past, you should at least name your device model and ALL earlier actions done so far - even if only the least of AVM's routers use And to EACH other reader in the future: DO NOT try to flash any data to your router, if you're not really, really sure, what you're doing there. That can be dangerous (and it WILL be so, if you're only guessing) and permanently destroy your device - and I'm not in charge of it, even if you use my software to hurt yourself (or your device(s)). |

You were NEVER supposed to change your bootloader - never ever. Thank you for clarification, I had an distinct Intention, i will try to lay down what i tried to do, and what i did. In best case it's useless and unnecessary - and if things go worse, you'll brick your device, maybe you've done it already. I have (had) a branded (kdg) F!B Cable 6591 which was sitting in my shelf for some years now. It just now happened that we (At my Company) got the long awaited fiber-optic Internet Connection. I wanted to use the Cable 6591 to Dial into the Fiber Connection via WAN(LAN1) but then I discovered, that my branded F!B has most of the Menu Items disabled in regard to the Retail Version. But to get ANY clue, what your original intention was and what you REALLY did in the past, you should at least name your device model and ALL earlier actions done so far - even if only the least of AVM's routers use mtd3 for the EVA loader. I flashed a freetz Image to the Cable 6591, got SSH and FTP Access, read out the MTD3, changes the firmware_version and the "DMC RTL" from "kdg" and "n" to "avm" and "y", at least that was what I tried to, and then I flashed the MTD3 via a Putty Command. What i really did, was flashing "AVM" instead of "avm" and "Y" instead of "y". And to EACH other reader in the future: DO NOT try to flash any data to your router, if you're not really, really sure, what you're doing there. That can be dangerous (and it WILL be so, if you're only guessing) and permanently destroy your device - and I'm not in charge of it, even if you use my software to hurt yourself (or your device(s)). Even if it doesn't seem that way, I was fully aware of the possibility of bricking my F!B, it had no use for years and the Original Owner didn't want to have it back, opportunity came and instead of waiting several weeks for the 7591 for the fiber-optic connection i wanted to see, if I could unbrand my "kdg" Cable 6591. I just now happen to have some kind of issues writing back the "bootloader.bin" to the mtd3 partition, I corrected the values to the ones that should be there, and now I kindly wanted to ask for your assistance to be able to flash the data to the partition - i you could and want to help me I would be very grateful! Thanks in advance! |

Hello,
i sadly misflashed my bootloader and put AVM instead of avm and Y instead of y flags/variables.
With Bootloader i mean the file which i saved with the following putty command: "cat /dev/mtdblock3 > /var/media/ftp/bootloader.bin"
Now my device is in a very strict bootloop.
this is the script i try to run to write the corrected booloader:
.\EVA-FTP-Client.ps1 -Verbose -Debug -ScriptBlock { SetEnvironmentValue linux_fs_start 1 }
.\EVA-FTP-Client.ps1 -WriteBootloader -ScriptBlock { UploadFlashFile .\bootloader.bin mtd3 } -Verbose -Debug
.\EVA-FTP-Client.ps1 -Verbose -Debug -ScriptBlock { SetEnvironmentValue linux_fs_start 0 }
.\EVA-FTP-Client.ps1 -WriteBootloader -ScriptBlock { UploadFlashFile .\bootloader.bin mtd3 } -Verbose -Debug
but i get those two errors:
================
DEBUG: Sent
STOR mtd2
DEBUG: Response:
501 store failed
or.
================
DEBUG: Sent
STOR mtd3
DEBUG: Response:
501 unknown variable mtd3
================
i dont know which mtd i am supposed to write to, and i seem to have a syntax error or a definition error when writing to mtd3.
could you be so kind to direct my way and shine a light? which mtd am i supposed to write my bootloader.bin to, and how do i do it? i struggled for hours to make the script work but sadly i fail and am stuck here.
thanks in advance!
i also had to modify the discover.ps1 to not put the bootloader to hold, else i am not getting a connection at all.
