XR1000 won’t update beyond firmware 1.0.0.78

Hi,

I’m having an issue updating my Netgear XR1000.

• Current firmware: 1.0.0.78_1.0.65
• I downloaded the latest official firmware (XR1000-V1.0.2.86_2.1.40.chk) from the Netgear website.
• Updating through the web interface always fails with a firmware update error.
• I also recovered the router successfully using nmrpflash, but after recovery it still boots into 1.0.0.78 instead of 1.0.2.86.
• The router works normally, but I cannot upgrade to any newer firmware.

Has anyone experienced this issue before? Is there a required intermediate firmware version, or is this a known problem with the XR1000?

Thank you.
