[Help needed] Nearly done - Support for Netgear WNR2000v5

Could someone help with the last part of adding support for the Netgear WNR2000v5?

Forum talk on openwrt forum about that: https://forum.openwrt.org/viewtopic.php?id=61256

Summery:
Support is nearly done. Profile looks like this now:

wnr2000v5_mtdlayout=mtdparts=spi0.0:128k(u-boot)ro,3904k(firmware),64k(art)ro

and

$(eval
$(call
SingleProfile,Netgear,64kraw,WNR2000V5,wnr2000v5,WNR2000V5,ttyS0,115200,$$(wnr2000v5_mtdlayout),0x27051956,WNR2000v5,""
NA,-H 29764648+4+0+32+2x2+0))

Probably last problem now: Device run into a second magic number check. Serial output error: Second part Bad Magic Number

This second magic number is written in memory space 000D0040.

What is now unknown: How can a magic number be written at a special place in the middle of the LEDE firmware? Could someone take a look at the forum post and help fixing this last thing?

A precompiled firmware for the users to test would be great!

Thanks!

Support for this device is working fine:

As a user I stumbled into this, installed- working fine. Wanted to just say thanks.Very little out there on web for this model so guess main pages do not reflect this build yet.
