Thought I’d post this here it may save someone looking for something that is no longer available,
Also maybe someone knows where assistant has gone for the controller in the title.
So today but almost tomorrow is now today & for the last 8 hours I’ve been trying to re flash my FW on the controller in the title above ( why ? ) well, because recently wherever I go I seem to be getting real bad interference which I’ve mentioned on here before, also, when at the last two meets I mentioned it & naturally thought we were in a high interference area but, everyone else said they are having no problems hence the re flash today which I’ve been trying to avoid,
Well, moving forward plugged it into DJI assistant 2 for consumer drones but it’s a version from last year, so went hunting for the later version thinking it might be that ( that’s stopping it from flashing ) but I couldn’t even find DJI assistant 2 consumer drones that ( lists ) the rc pro rm510 a later version & can’t even find the old one either 
Reason I’ve been trying to find the later version was because although the old assistant is showing 3 options of FW ( 03.02.0700 ) - ( 03.02.0800 which I’m on / was on ) also available is ( 03.02.0900 ),
So after messing around wondering why it won’t refresh & it comes up this error but highlighted in red [dji assistant 4-7-1 download failed] that’s what it kept saying, so after checking the anti roll back values those three FW versions above are all ARB VALUE 1, so after head scratching thought I’d try & drop down to 0700 which it done using the old V of assistant, so then thought I’ll see if I can get it back on FW V 0800 ( nope ) kept failing again with the writing in red after many attempts,
So I thought 
I’ll use dank drone downloader & flash it on the DH website ( nope ) failed about a dozen times when it got to around 70% then the Dell latitude kept crashing so it needs to go for repair ( I think ), this all started at 4pm it’s now gone 12 at night 
Anyway thought I’ll type in google to see if DJI have removed that version from there servers & this is what Google said, if only I had checked earlier on but did not as I thought what’s the chances hey ! 
However moving on from that as I now know regarding the FW, where the hell has the Rc Pro Rm 510 assistant gone the latest is below or am I missing something, thought I’d share anyways .
Edit : was meant to state I thought & have many times used DH to roll back the FW or whatever which allows you as long as the roll back values are correct to do so but as said it won’t have it regardless, on the flip side I don’t now want to be putting FW back on that has / is apparently been binned for good reason
