Hi Guys
i apologise for my lack of presense on my own topic
i have been very busy with work
Reading through all your posts
@ Neddie - I'm glad you got it worked out
AS FOR THE REST OF YOU GUYS
obviously , it seems that rigol has decided to try and put up counter measures in the new firmware version 3.0.1
I've heard a few stories here
Story 1 - Some people are having success with the upgrade using the utility - This has been verified
we are still not sure why everyone is not able to do it
Story 2 - as dumb as this sounds ..... Apparently Certain USB stick brands won't be detected during upgrade.
so.. let's start mentioning what brand of USB stick we are using and see if a pattern emerges
keep in mind we only want to hear from those of you who have a meter that started on Version 3.0 and Upgraded successfully using the Utility
Story 3. THIS IS VERIFIED
The JTAG Method
Bite the bullet and just do it
here's the link to a step by step procedure
https://www.eevblog.com/forum/testgear/sniffing-the-rigol%27s-internal-i2c-bus/msg365951/?topicseen#msg365951Story 4. this is verified YOU CANNOT ROLL BACK TO A VERSION PRIOR TO Version 3, if you are on Version 3
I'm still happy to help anyone who is having trouble and has Firmware below version 3.0
Thanks for all your participation guys
