Hi,

I have DSO4254C with serial number CN1829002001839. I didn't use it for couple of monts. I powered on it yesterday and it did not boot. It hangs on startup screen.

I also tried recovery menu but it didn't help too. F2 option still hangs on QR code screen. F3 option with latest firmware which I downloaded from Hantek website also
fails. I use a 8GB usb stick.

Could anyone provide an older firmware for this device please.

I alse appreciate for any other advice.

There are a few troubleshooting steps you can try. First, make sure the QR code is clean and free of any smudges or damage that could prevent the scanner's ability to read it.
