Are you sure you tried the file? This device contains a special software file that cannot write to another device that matches it. Each device has its own license inside the software file. I am sure of what i say. I made my own program in which I put a valid software copy and a corrupt software copy in order to copy the important content from the damaged copy to the valid copy and then rewrite the valid copy that was modified on the device, otherwise if you write a valid software copy without modifying it to the device you will not be able to perform Record and you will see a message informing you to refer to the manufacturer.

I will upload two different files for you, write them and tell us the result.

К сожалению, я не смогу выполнить вашу просьбу: данный видеорегистратор поступал мне на профилактическое обслуживание и, в настоящее время, давно выдан заказчику. Проверка осуществлялась путем считывания и сохранения дампа прошивки из spi-флешки, стирания этой микросхемы и, затем, записи сохраненного дампа назад в эту же spi-флешку.

The problem appears when you rewrite the software to another device and not when you rewrite it to another SPI. Thank you for your reply and follow up.
