Question: Can you share your firmware files TDS794D

Hello, just out of curiosity, why do you need firmware for your TDS794D ?
The pictures you have shown are from your TDS794D ?
If yes, how about you use USB-GPIB to copy the 3 files (firmware, EEPROM calibration and NVRAMs) ?

Hoi
I can confirm that it is possible to convert a TDS744 (Non A) to a TDS784A. and from firmware v1.0e to v4.2.1e. the first time it didn't work and I had a mismatch with firmware verification. that probably had to do with the fact that the firmware erase did not go well right away and had a few retries. I continued to repeat the firmware removal process until everything was 100% removed at once without retries. then load and check the new firmware. I did everything with the tektool. and the correct order was followed. Please note that a full calibration is required due to firmware upgrade and bandwidth.everything of course at your own risk.
