MSO2000 Application module hack
Edison517:
I wrote a quick program for Arduino that will program the 24LC08 chip to any of the 3 possible combinations. Just hook up the I2C lines and power & ground and run the program :)

After some work, I`ve removed password for root, accessed command line and went into dir /usr/share/tek where i found "fw_setenv" and executed:
./fw_setenv model "MSO2024"
After that, my oscilloscope thinks it is MSO2024.
I think it could be possible just changing fwEnvUpdate.sh. So you have to mount firmware.img, change fwEnvUpdate.sh, change md5sum.txt with new md5 for fwEnvUpdate.sh, umount and that`s it.
To change the file, put before last line of fwEnvUpdate.sh:
$FW_SETENV model "MSO2024"
echo "Finished updating environment variables."
Besides showing MSO2024 I can't test performance after modification. If someone tested, please tell us.
Sorry about bad english.
Thanks.

I found this https://github.com/dmitrodem/tek_softhack, and install the modified firmware in my DPO2012B and all modules was unlocked, but i have an issue, without the modified firmware autoset take 2-3 seconds to work with 1M point record, with the modified firmware it takes about 5 and a half second, any one with hardware module can check this. Same for math functions, and i dont know if affect the decode of buses. Can someone confirm, i can share my update image.

DiodomanX,
Thank you for the tip for software unlock.
About autoset, I measured the time and it is about 3.8s with 1 channel enabled and probing 1kHz compensation signal. With or without hardware keys.
But when I enable all 4 channel the time rises to 7s.

Then it is normal that time is increased, some progress in testing to increase the bandwidth?
