Hello Sotona.

I assume the original language is english, so I respond in english for better understanding.

Unfortunately I have no idea if there's a full Flash Rom dump somewhere or how it can be created from a working repeater to flash it into a repaired one.
AVM only provides (update) images and, since this repeater has a LAN port, a Recovery tool. Both can be found at > ftp://ftp.avm.de/fritzwlan/fritzwlan-repeater-dvb-c/other/ <. Folder "fritz.os" contains the current firmware, folder "recover" the matching recovery tool.

Unless the bootloader is broken as well (resulting the Recovery tool cannot find the repeater at all) it should be possible to either use the recovery tool or the RUKernel tool to flash the image into the new flash rom. Maybe someone more experienced with said tool can advice you to extract the needed parts from the firmware image and flash them into the brand-new flash rom.

Thank you for the answer! but unfortunately the contents of the flash memory and the bootloader are corrupted and these methods do not work I tried to find a memory dump of this device made by the spi programmer but unfortunately found nothing!

I'll try Raise topic

I would bet, there will be no further answer ... at least not in the public.

Opposed to (parts of) the FRITZ!OS software (where distribution rights are inherited from the (L)GPL license, which is valid for some parts integrated by AVM), the boot-loader code is not open source and AVM's own software license prohibits copying and distribution (http://ftp.avm.de/archive/fritz.box/license.txt - there's no download source for this license file in the new file-system structure on AVM's download servers).

As long as AVM itself doesn't provide this software "to the public", you'll not get the requested files here ... no other source may provide it, 'cause it would violate AVM's license.

I did not ask for the source code of the boot loader and did not ask to crack the loader! I want to restore the bootloader in the device in which it failed due to the manufacturer!

Are you able to read?

Quote from AVM's license text:

Software is delivered in machine-readable format only (object code format). Under all AVM intellectual property rights, AVM hereby grants licensee the non-exclusive right to use the Software.
[...]
Licensee shall be entitled to make a copy exclusively reserved for personal backup purposes (backup copy).

Look at the German copyright law (UrhG) and the needed entitlements, if you (or anybody else) want to make a copy and distribute it to anybody and you'll get an idea, what I wrote and why I did this.

It needs no context with "source code" or "cracking the loader" (what should this be?), to violate AVM's rights as copyright holder - copying and sharing isn't allowed, even not in binary format. If you need or want the data, ask the copyright holder ... that's AVM in this case.

If your device is out of order, use the offered warranty from manufacturer to exchange the device, if these conditions are met:

Within the warranty period, we will remove defects to the product which are demonstrably due to faults in materials or manufacturing.

As you stated above, the malfunction of your device is "due to the manufacturer".

AVM offers a 5-year warranty to the owner of a "FRITZ!WLAN DVB-C" repeater (https://assets.avm.de/files/docs/fr...-dvb-c/fritzwlan-repeater-dvb-c_man_en_GB.pdf - pg. 46) ... your device may hardly be older than 5 years, because it was released in fall 2014 first.

BTW: Full-quotes aren't really liked here (there are rules for this board) ... please take it into account on a further answer (if you think, it really needs more explanations).

I need a bootloader! loader there U-boot GNU GPL

 

[PeterPawn]

Than you should use "u-boot" as loader ... AVM does not do this, as far as I know.

They use an own modification of (some commonly known) initialization code and they call it "EVA". I don't know, whether they've built it from scratch or if it's based on an earlier loader by TI (for which they had a license).

But this loader is neither public domain nor open source software (and not GPL-licensed, too) ... and all rights to copy, use and distribute it, are held by AVM.

This manufacturer entitles you a right (by its license) to use the loader code in exactly one device, which was sold to you ... but this does not include any permission to copy or distribute the binary data for/to someone else.

If you think (or know for sure), it's a only an "u-boot" derivate, write to AVM and ask for the sources ... because "u-boot" is really licensed under GPL, they have to hand it off to you.
