![]() ![]() Right now for example we only have one FW for board revision 2.0 and none for 2.1 or 2.2. I'll add it to the archive and update this post. Here is a repository where I intend to store everything I'd like to ask anyone who has received firmware from OWON to post it here with details like board revision, board date, fw updating from, the first 4 digits of SN or any info that could help anyone else in figuring out how to upgrade without bricking their device really. ![]() Unfortunately the attachment upload limits don't allow me to upload the whole packed folder here (not even just all the compressed fw files) so I am sharing it on Google Drive here and here is a GitHub gist of the Info Doc. I "think" it should be safe to update to fw v3.3.3 that uploaded, but I'd feel a lot better if anyone who has done so could confirm it worked for them While reading this thread and trying to figure out what is the right firmware for my board revision I compiled all the info I found in a document I am sharing below, I have also collected all the uploaded firmware files and images of hardware revisions. ![]() Hello everyone, I'd like to update the firmware on my OWON HDS272S HW v2.0 FW v3.1.0 serial number 2124xxx. Looking at the screen highlights prior to pressing the AUTO button makes it a little less frustrating because you'll know what to expect and whether to hit the AUTO button a second time. In all other modes, it works as it should. I found that the toggle to CH2 when hitting the AUTO button ONLY happens when the screen indicates that it's in the CH1/2 mode. Each of these modes will highlight their respective function on the screen. They are: CH1/2, HOR, Trig, Measure/Range. Note that the scope mode has four different display modes (for lack of a better way to put it), and each of those modes will dictate what the blue arrow keys and the "F" keys do. ![]() The workaround that I used was to simply hit the AUTO button a second time to toggle the "focus" back to channel-1 (see exception below). I also understand you could brick the unit if you try to load firmware not made for that board version. It has supposedly been fixed as some point for the firmware for later board models. From all that I've read to this point, there hasn't been a fix for a firmware version that would run on the V2.20 PCB. ![]()
