When start the 4004BC Series Oscilloscope, it only displays Start-up Picture as the follow picture, can't enter scope interface, please operate as follow steps.


1. Refer to the video "4000BC recover" to operate.


2. If can enter the recovery interface, please press F2 to recover the system and press F1 to confirm.

If prompted for recovery failed, copy the recover_up_190506.up file to your USB stick (FAT32 format, less than or equal to 16G) and insert it into your scope.
Refer to the video "4000BC recover" to enter the recovery interface again. Now press F3 to update.
After update, enter the recovery interface again, and press F2 to recover the system.

Firstly i tried to restart but nothing  ...

Referring to video operation, can the oscilloscope still fail to enter the recovery interface?

What steps have you taken, and then can't continue?

I have followed all the steps that were given in the video.

Thanks to murkasp i was again able to enter the recovery setup but when i pressed F2 again the message was operation failed. I have tried uplaoding the patch few times and then recover the system but i get the same result everytime.

My oscilloscope is DSO4254C. Will the .up patch work for this oscilloscope or if not can you guide me to some other place where i can find the patch for DSO4254C
