Tektronix TDS1000B and TDS2000B series hacks
clodnut:
U902 is not the firmware flash -- it's just an I2C EEPROM, apparently containing the boot code for the USB controller (according to this earlier post).
You will need to remove the S29JL064H flash memory chip, typically designated U801.
It's the one pictured in this post earlier in this thread. It's the chip with the label in the top left of the board shown in this post.
Then you need to read the chip, patch it using braikin's Python script and re-solder it into the scope.
Good luck!

Thank you for the tutorial, please wait my results.
vanbac:
thanks "clodnut" very much, i have upgraded the bandwidth, this is my model.
CaptDon:
How would I run the .py script to program the flash device. I have an assortment
of programmers, but none would understand a .py script. It seems I need to unsolder
the flash rom device and insert into a programmer, I am o.k. that far, then what??
clodnut:
Hi CaptDon,
Per my earlier message in this thread - you:
* Remove the chip
* Read it in a programmer (using whatever software is appropriate for your programmer) and save the firmware image somewhere
* Use the Python script to patch the image
* Write the altered image back to the chip
* Reinstall the chip.
Good luck!
