When a device (PC, USB device, etc.) malfunctions and cannot work, there is a last resort, "factory default".

In that case, all settings on the device will be lost, but you can still use it if you reset it.

However, there are devices that do not have this "factory default" reset button. Now I am in trouble with this.

There is no problem if there is enough response time, however these issues are emergency situations. In fact, now I am in an emergency.

As it is an overseas manufacturer, there is no time to ask questions. So I have to try the restoration on my own.

All day, I searched the Internet, and finally I found a page to rewrite the firmware, however,

"Honestly, rewriting firmware is scary"

This firmware overwrite has caused me to encounter the situation where the device completely stops working.

- Despite the problem, the device is almost moving

or,

- Devices that can both solve problems beautifully and completely stop working

I will be forced to make this decision.

Generalizing this fear in an event three days later:

No confession, but keep a good friend

After confession, accepted successfully , or no accepted with uncomfortable friendship.

It can be replaced ...No way!, Never!!

Absolutely, I am more serious than you.

I want to tell you "Fear of a system that doesn't work".

Compared to "this my fear", your fear of confession is nothing.

I can affirm that.
