I just decrypted the file cpl.bin from 2 different Fluke v8.04 firmware upgrades;
one that claims having bushealth support (19xC_2xC_v804.zip) and a regular one (FlashTool_19xC_2xC_V804.exe) with out it
While data.bin are both identical, cpl.bin ( it contains the upgrade command sequence) are different.

cpl.bin decrypted no Bushealth

Hi squadchannel

I have a 199C and last week I got a THS3024, yesterday I read your thread, awesome job.
One of the posts mentioned that that some parameters can be set in FlashTool.ini and today I got lucky and coded a very basic
deofuscator, sure someone will find some use for it

Best,
Pat
