I did not understand

I have a DVR with corrupted Kernel.

Getting the recovery files to the manufacturer.

By U-boot update command I'm not getting the correct kernel.

By SDK recording program HI-3531 chip can replace the U-boot for another version more when I try to do with the kernel displays the following error Invalid nand flash block size!

Someone forum would know what generates this error and how to fix it?

Some forum user NVR has this model?

My during an update corrupted firmware and I'm seeking a copy in order to get it back.

I've tried with the company that sold me and the manufacturer both more were not willing to help

It has two months I'm trying firwmare with them and I can not.

It's only been me update files (attached image).
