Undetectable USB drive!

Thank you very much, but what is this program used for precisely? Is it reliable? (without viruses and the like).

It's useful to know the components of the key.

May I know what this could be used for? (Sorry to bombard you with my questions)

To see if we can repair it (Flash its firmware)

Okay, I'll install it and keep you updated.

I installed it and launched the program, what should I do next?

Did you start ChipGenius...exe?

Right-click in its window and paste it into your next message.

yes, here is what I get:

Tools on web: http://dl.mydigit.net/search/?type=all&q=FC1178BC

I see it's a 16GB key or less = write 16GB but it could be 8!

The controller is from the brand FirstChip and model FC1178BC

You can find tools to flash it here https://www.usbdev.ru/files/firstchip/

I don't know if you'll need software from the section FirstChip FC1178/FC1179 ApTools or FirstChip FC1178BC ApTools

But you will definitely need software from the section FirstChip FC1178/FC1179 MpTools or FirstChip FC1178BC MpTools

You can start by trying the latest versions; if the key is not detected, you can try other versions, older versions...

You can check in Settings for your preferences, and Start to begin working.

My USB key is 16GB, I didn't quite understand what I was supposed to do because the website is in Russian it seems ^^'

Start by downloading FirstChip FC1178/FC1179 MpTools V1.0.4.5 (2020-08-25)_0831; FirstChip_MpTools_20200825_(0831).rar; size: 3,798,405 bytes.

Extract it with 7-Zip and start FCMpTools.exe.

So, I'm on the software but I don't know what's written; it's in Japanese or Chinese o_o

On the right, you can select English, it's easier.

phew, thank you

So what should I do now?

Either you check in Settings if everything is OK (Normally it should be by default), or you click on Start.

there is apparently a password

I said nothing, I have access but I don't see any "ok".

Make a capture so I can see.
