Took another look at you pictures and I have some things for you to try and a question to answer (see photo)
Get your self a roll of black electricians tape, this is very common and inexpensive and can be found at any hardware store and sometimes even grocery stores.
Peel back the aluminum tape that's covering up the exposed soldered terminals on the bezel and replace the green tape (I am assuming that's what's under the aluminum tape) with the black electricians tape.
The green tape that is visible _ try replacing it with the aluminum tape to hold down the folded over tabs.
I will see if I can find a new bezel somewhere as they are getting hard to come by.
I don't honestly know if a new bezel will solve the problems, logic says that if the grounding procedure did not work, then the bezel is at fault. There is a post some where, where a HP employee admits that the double sided sticky tape that holds the bezel together fails and causes the mis-fires.
As for connecting your LAN line directly into the laptop, ounce it's plugged in and becomes active Windows will automatically switch to the LAN line ounce you wonder outside the range of your WiFi radio.
If it does not detect the LAN line then you will have to set up that connection the "Network and Sharing Centre" in the control panel, and ounce this is done it should detect it automatically.
Great photos by-the-way, the resolution is nice and high !

Your second note: the guy who did it, just put the aluminium tape instead of the yellow one you used on your videos.There is nothing under it... So I have to unstick the aluminium tape and put the black one instead?
I don't understand you first note very well. The aluminium tape surrounds the cable all around. I'm not sure that it was made from one single piece of aluminium. Is it important?

I thought you did it yourself.
I'll take some screen shots of my videos and explain what it's all about, but from what I can see in your photos, it's not been done properly, in fact, done incorrectly it can make the problem worse.
The whole concept is very simply, all that aluminium tape is a just like a lightening rod to direct the static out to ground, in fact it's exactly like a lightening rod since static is essentially lighting, but on a very small scale.
Lets say you have a lighting rod on the highest spot on a building. The lightening strikes that first before the building because it's placed higher then the building and the rod itself is connected to a heavy wire(s) that runs down the building and into a copper rod literately hammered any number of feet right into the ground. This gives the lightening a place to go, the whole point of it is to direct the lightening away from the building.
If you were to cut the wire that connects the lightening rod to the copper rod that is in the ground, the lightening would still strike the lightening rod itself, but because the wire is cut the electricity would find some where else to go, perhaps a metal frame on a window and then from there to the metal studs inside the building and then into the wiring. When it gets that far it can do all sorts of damage.
In the case of your laptop the aluminum foil tape serves both as the lightening rod and the wire (path if you like) for the static build up to go. If the path is incomplete the static is not dissipated and all it's doing is spreading it around as far as the break in the path is concerned and making the problem worse.
If you rake two pieces of the aluminum foil tape and stick them together the static will not pass through where the two pieces are stuck together, This is so because the adhesive on the back of the tape does not allow the static to flow through it, it's the same as cutting the wire from the lightening rod to the copper rod that is in the ground.
On the ribbon cable in your photo the guy looks like he simply wrapped the cable in the aluminium tape, this serves no purpose. The tape must be folded under so it makes contact with the HP foil that is already applied to the ribbon cable.
If there is an area where the static has no place to go because your guy did not complete a proper path for it, all he did was spread teh static around and create a bigger problem.
The whole ides is to direct the static to the silver plate where the DVD/CD drawer is. The plate is a good ground and if you were to follow to where it's connected with in the laptop you would eventually find that it's connected to the ground in your house wiring and into the copper rod outside in your yard somewhere next to the house.
Did you watch my videos, part 2 shows me how to wrap the ribbon cable properly ?
If you still don't understand, I will make a follow up video that explains the grounding concept in more detail.
If I have time...
To answer your questions,
So I have to unstick the aluminium tape and put the black on instead :
Yes, you have to unstick the aluminium tape and place the black tape here over the connections first. The connection are sort of sharp and they may poke through the adhesive and short out the connection. I don't think it will damage anything, but it may be exasperating the problem.
The aluminium tape surrounds the cable all around. I'm not sure that it was made from one single piece of aluminium. Is it important? :
It's very important, my explanation above explains why simply wrapping the cable in foil does no good, where the adhesive contacts the HP foil that is already in place, the static stops there and still causes the POP-UP problem. By folding the ends over the foil tape and then sticking it in place, it makes hard contact with the original shielding. This completes the path so the static can get to the metal DVD/CD cover where it dissipates.

I'm very grateful to you for spending your time on the very detailed and precise asnwers. I understood everything you explained.
Tomorrow, I'm going on holidays, so I won't be there for more than two weeks. During this time, I'll disconnect the bezel and after my return I'll come back to this problem.
First of all, I will check if the aluminium is really folded under. I think the guy did it, but I will double-check it. I will also make the isolation for this cable from one single piece of aluminium. This time, I'll do it by myself.
You adviced to use the black electrician tape, but I think mine is the same, it's just the color that changes...

The role in the video is not the copper tape from Amazon, but an aluminum tape that was purchased in a hardware store. It's cheaper and more readily available then the copper tape.
There may also be a problem with the copper tape, that is the adhesive that is supposed to conduct electricity my not be doing it's job properly. Use the aluminum tape in the videos and follow the instructions there exactly .
I had used the copper tape in my machine and the problem returned, upon testing the adhesive for continuity, the resistance was quite high, so use the aluminum tape cut from the large role.

I'm really not lucky... Before going on holidays i just disconnected the wire because i didn't have any aluminium tape and my wifi was going crazy. Today, I dismantled my laptop to isolate the wire properly and i found out that the wire's just burnt... OMG
I think I had to isolate it and not just leave it in contact with other parts... It was, actually, in contact with aluminium which covered the bezel... (hopefully, because otherwise it could have completely burnt my laptop!)
So, my question is: could I find this wire somewhere?....
Thank you very much!
I'm just showing you my poor wire...

Chances are you may have to buy the whole bezel along with the ribbon cable.
Does the machine still function OK ?
I am assuming that you have removed the cable entirely and tried to boot up ???
I'll have a look on ebay and see if I can find one _ I may have a spare myself.
I found one, you will have to contact him for shipping in your area.
Here's the whole thing, with what looks like the cable as well _ contact the seller and make sure the cable is included if you go this route.

Exactly what one would expect to happen under the circumstances! HP should have accepted responsibility for this design flaw a LONG time ago, recalled their laptops, and wrote off the loss.
