The cypress chip has no internal eeprom, the FW is stored in a eeprom chip 24LC64 (IC U807) on the other side of the board, and it is loaded to the MCU during power up.
Which version of the HT6xx4 do you have? If you can damp yours EEPROM content and post it here it would be nice.
There is no hardware difference among the models, the BW is limited in software.

Attached to my previous message, so you potentially could find out which my scope model is...
Just wonder if anybody can upload the eeprom from 6254bd model

That is what I asked. I have the eeprom from a 6074bc and I would like to compare it to the 6254bd model, maybe the BW configuration is in there as the hardware are the same.

Managed to run DAC , but the main part which is pll init and adc read is not yet done.
Appocalypse_br:
Hey many thanks for the firmware, i am little noob in these i2c field can any of you guys help me trough the process of backup and write the firmware in my unit, many thanks, if you have some link to tutorial video or make a quick one will be great.
(mine is bricked itself no red light blink anymore)
thanks a lot.
[EDIT]
Just found these hey great work!
