Hikvision firmware upgrading failed (language mismatch)

The message: "Upgrading failed, firmware mismatches" or "Language mismatch" shows up on a Hikvision DVR, NVR, or IP camera when you are trying to use the wrong firmware for the device. Let's talk about the solution to this problem.

Hikvision Upgrade Failure Language Mismatch

Hikvision DVR shows the "Language Mismatch" error message.

This problem is very common with HIkvision OEM DVRs. 

What causes the upgrading failure

Usually, the upgrading failure occurs when you try to upgrade a non-official Hikvision camera or recorder or when you have the Chinese version of the device.

Some DVRs sold on Amazon indicate the OEM version, as shown below.

Hikvision does NOT support OEM devices, and the firmware available on the official website won't work and will return the message "Language mismatch".

Another reason for the upgrade failure is related to some glitch on the device's internal web service. Even if you are using an official Hikvision device, you could see the error message displayed on the screen. But there's a solution to this issue.
