I am new to all this stuff and have just spent 2 days trying to upgrade the software on my recently purchased DSO201. It has been a nightmare, particularly when one attempt just caused the thing to produce a white screen that gave the impression I had messed the whole thing up permanently. However, I have now sorted the problem and have a much easier to use piece of kit. All thanks to rimidalv007 who is, in my humble opinion, a genius. Thank you. I shall keep an eye on this topic to see if there is more wisdom to come. Thanks again.
