Hi @jagibson,   You are right, someone from HTC staff has called me this afternoon (to be honest, it was a really good conversation I had with that person). I have to send back my controller to the repair center, and they will send me a new one.   The person i had explain me the whole process (the repairing one), and i know understant how my controller came back with the same defective sensor : as sensor are not really tested, but calibrated, the default couldn't be realy seen by the repair team. That didn't excuse them, considéring they could have test it to see if was really functionnal or not, but...well...i understand the case at least.   I want to thanks both  @jagibson , @Synthesis and @VibrantNebula considering that a part of the french support wasn't very useful. I fould here a lot of support, useful information, and of course, skilled staff members :)   I'm also glad that this issue will be (normally) resolved with a good end (ok, I totally aware of the Murphy law, and the whole process is still not finished, but hey, let me hope that everything will be alright XD).   I will put this issue as solved as soon i will receive the new controller (and obviously, tested it XD)   Again, thank you very much :)     PS: by the way, they are very intriged by the issue I had, and they want to test my controller to see what the **bleep** was really happening (they cannot see why this sensor can mess with the whole traking system)     As a bonus to this conversation, here you can find a tips that can certainly solved every USB problem you can found (for HTC Vive or any other stuff :p) - I'm in good mood :   Mouahahahah   Happy new year to everyone ;)   MrSojiro ...

By the way, my idea came from this post :   http://community.viveport.com/t5/Technical-Support/flashing-grey-screen/td-p/8607/page/13 ... View more

@Synthesis, @jagibson , @VibrantNebula   Hello everybody,   I got a surprise for you : after 3 RMA procedure, the controller......IS STILL NOT FUNCTIONAL !!! (yay)   I didn't got any repair report this time (for the moment i suppose) but according to what i can see, they have changed....the motherboard again !!! (the controller was asking for a firmware upgrade) T_T This is a sick joke, really. And I suppose that everything is alright for them, considering i get my controller back.   But hey, I got A GOOD NEWS !   While manipulating my defective controller, i remembered a post were user had grey screen  issue linked to a defective sensor (you can find that on this forum). So, i had the idea to hide each one of my sensor, one by one. Guess what : TEST n°2 was VERY USEFUL !   Indeed, i discovered that when I hide THIS sensor :   this one is guilty as f*ck   My controller got fully fonctionnal. So this sensor is giving wrong information about the position of the whole controller....(when i remove my finger or my IR occlusion système A.K.A pile of post-it, the controller is going crazy again...)   How the hell did my controlled passed their testing bench....how....       I suppose now that I have to lunch a new RMA procedure....for god sake....       Tell me you can do something for me , because this is now clearly enouth.....   I successed where a entire repair team  failed. Ok. (i'm talking about the one in the repair center ;) )   MrSojiro   ... View more

@Synthesis, @jagibson, @VibrantNebula   Hello everybody,   This is the 50th days aniversary of my RMA procedure, so we have to celebrate it with a cake, or whatever you want.   No it is not ! So, my controller is at the repair center (Romania) since Thuesday, and i would like to know what decision the repair center has (or has not) already taken about it : - did they decided to repair it - or did they decide to (finaly) replace the entire unit   Here you can get the ticket number you need to grab this information : 117496888791   If I understant it well, RMA procedure are usualy 5 worked days long, so, i won't be abble to get it before the 25th of december. Considering this is Christmas, i won't be abble to get it before the 26th or 27th of december (it can be worst : maybe they will send it in 2018..... *sigh*)   I was with the support chat earlier this morning, I had "Chantal" in line, who was not very helpful, as usual. So, here I am again :D     Bytheway, If I can't get in touch with you before the 25th or after : Merry Christmas to everybody, and I wish you a happy new year   MrSojiro ... View more
