Nighthawk X4S R7800 does not upgrade

[Twinsen]

Just read the news about this router being vulnerable for hackers attacks and found a new firmware file on netgear site.

However, the router itself does not accept it telling me that this new firmware is not supported. I get two kinds of errors. For attached file I get: "This firmware file is incorrect! Please get the firmware file again and make sure it is the correct firmware for this product." and for a firmware update assistant I first get the notification that the new firmware is found (current version: 1.0.2.04, new version 1.0.2.90) and then after I press yes, it downloads it and says "MD5 verify error". So either way I can't upgrade it on my own. What else could I try? Thanks in advance.

Under the downloads section click on "+view previous versions"

Try a stepped approach. Go a couple versions newer and see if you can update.

the version you're on is around 22 versions behind. You might try doing a stepped process versus going from 0 to 100.

Thanks! I believe I can only find the most recent version on netgear site? Where should I look for the "middle" versions?

Thank you, it helped! I've gone from 2.04 to 2.28 to 2.40 to 2.52 to 2.68 to 2.80 to 2.86 (previous version) to 2.90 and it worked this way!
