 okay guys so this is something that you might come across and that is where wouldn't do your your quad is quite happy at DFUing so you can update the firmware and then the next day it doesn't now I'm gonna click this in I don't know if you can hear that clicking but that's clicked in holding and now when we look across we can see nothing's happening and in a few moments the computer's gonna throw an error and so it does not recognize this now I've updated this before there's the error and I've updated this before like this and it's worked I think I've even shown people how to update with this and it's worked but unfortunately it doesn't seem to be working now now we might first assume that it's going to be maybe the drivers but on further inspection which was to basically get another board exactly the same this is they're both Matek F405 STD standards I hope that means or anything other than you know an STD so here we go this is another board exactly the same so it's just still got some of the connector wires on so I'm gonna click that down and I'll plug it in oh didn't click it down hard enough let me just pull that out and just it's a bit right by the edge here so it's gonna click that down quite firmly and then push that in have we gone to DFU now I can't seem to press that in firm enough oh yeah no it hasn't worked on here now this is not because of this this is because of the way I'm pressing this in and I hope maybe that's what's going on on the other one as well so let me just keep pressing that in a bit and just kind of shove that in okay so this one's gone into DFU now but I do not like the way these wires are so I'm gonna just do that because the way the wires are there on the back I'm not comfortable with leaving that like that they may not have been touching but I just don't like the idea of that so I'm gonna put that back in there now and now it hasn't worked me pushing that in so I'm gonna once again put quite a bit of pressure on this to try and push it in and there we go we're in DFU mode now I'm hoping but maybe this this is what's going on with this but this can be like that you might find it difficult sometimes to plug in I mean look at the look at the gap difference there look that you've got just try and push that down seems a bit daft really but well first somebody made with bigger fingers so I'm gonna quite forcibly push this down and that happens several times with the other one so I'm gonna just keep trying this a few times I'd much prefer it to you know just work trying to push a squarely on it as I possibly can no I'm not having it on here so all I'm gonna have to do is I'm gonna take this apart and get it out to see you know if I can get this to work and it's not it's just not having it all right so before it comes to much frustration that's exactly what I'm gonna do I've taken most of everything off anyway the only thing that's connected to it that could be affecting it sees and the 4.5 oh I've got my little nano receiver here and on the 4.5 I mean maybe that's what it is it's just pulling the power down a bit too much I don't see why that should be the case or it could be that the case was just not good enough but like I say we just saw that it worked on this one but of course this one doesn't have anything connected to it they may be wise on it but they're not doing anything they're not making a circuit I don't want them to make a circuit you could probably wise to take those off all right I'm gonna do that bit now off-camera okay so I've taken this off and I did just test it I know the outcome but I'm sorry I had some show on in the background and of course I'll be no good for the old youtuber what you call it so let's just press that in nice and firm you can hear it click look and we go and we get our DFU which is not surprising really two reasons one like I said I just tried it I knew the one because now it doesn't have the receiver connected drawing the current receiver might draw it's happier to go into the DFU so that's something you might want to look out for if you do build and then for some reason I mean mine was working before with all this stuff connected but now for some reason it doesn't want to work but never mind we're gonna continue now with the flashing of the new software which is the I now for so we can put it onto this okay guys and now we've got this still plugged into the computer gonna get this wire and there we go straight in DFU so that's that's using the same cable and everything it's yeah well for me on this it could be you know an issue you've had yourself before in the past and if you have how did you do with it but that's that's what I found with that and I'm hoping that will go across other flight controllers as well and do the same on other builds but I'll test it first I try and use the 4.5 volts again and see if it does it again it could be down to this cable this cable may not be suitable everything else that's five five volts on here you don't get any power the only way you get power on the flight controller is with the 4.5 volts when you're plugging in with the USB you only get five volts on other things like for the GPS and now the receivers not on because I've put it on a five volt supply instead which is fine but it can't be powered none of these things will be powered via the USB it's just that board now being powered and it's happy to be a few then so if you are pulling your hair out you are getting frustrated as I did because you know it's all right when you get it all going everything's working nice and you gotta take it apart again but hey that's just the whole part parcel of this and it's part of the phone really and figuring them out and name what's doing next on so I'll do now is I'll put a bit of flight video up okay guys so as you can see at the start of this some people when they put their kit together they looks nice and then when they put some throttle on it goes to garbage you may give it some power goes to garbage it seems to be with me what happens in mine is sometimes not all the time but you connect it and it looks like garbage but as soon as you give it some throttle and then switch it off it stays looking pretty good again so just pointing that part out there I'm just gonna stick a little bit of relaxing music on in the background it's no great flight it's just around the building and I'll see you in the next video
