Hello

I have a problem with my MiFi, it comes with a specific carrier and it is MTN, and when I insert an MTN sim card the router shows no service, I thought my router came with custom firmware so I have decided to download the latest firmware from the tp-link website and upgrade the device hoping this would solve the problem but when I chose the firmware and I click to update the update reach into 25% and message popup say that "the update file is not suitable for the current firmware".

Here are the screenshots
