I'm looking for a specific and rare HDMI adapter for completing my DIY phone.

wouldn't such swap cause mirrored pinout?

if not an issue, you do not need to do that yourself if you can find someone else with right tools and experience, like local repair service, usually for phones. maybe find one and talk to person working there before ordering part. my company did that when i was unavailable, i just send them instructions and they got parts (and it worked like a charm).

In my city its hard to find a shop that does that. They are scared to break everything. They don't want responsibility. The only choice for me is to find someone online.

the simplest and possibly the only solution at the moment is to make your own PCB. it can be wide like larger connector and 5-10mm long.
this is cheap and it would make soldering of connectors much easier.

optionally this can also be factory assembled - that service is called PCBA (PCB assembly) and it is not a bad idea to make few spares. usually minimum quantity is 5.

Sorry,I can't make a job like this. I don't have the tools and the competence. I'm not an electronic engineer. If I don't find the adapter,I should give the job to a PCB assembly company. The problem here is that a lot of these companies don't sell the product already ready to work out of the box to home. There are always operations that should be done to make it operative. So,I'm not sure if I will do like that. I need the adapter work out of the box when it comes to my hands.

i know... but you are stuck and the point is that someone could do it...

then you can either:
a) send design to order PCBs only, and have someone near you (like the repair guys) do the assembly.
b) send design and get both PCB and PCBA done by board manufacturer. in this case you get 100% assembled units.

this is an example of what ordering both PCB and PCBA looks like from JLC (giant PCB manufacturer, known for low cost):

It wouldn't be too difficult to lay out something like this or too costly to have JLC build several copies. The key information needed:

●The exact connectors required

●The connector orientation needed (i.e., which side is up on each end

● An accurate measurement of the length between connectors – it looks like they is some room for variation in length.

Welcome to AAC.

Somewhere in a box I have one of those. But I never used it because it would just become an HDMI port removal tool. The torque on the micro port is just too high for me to be comfortable with it.
Will you be mechanically supporting the connection?
Did u find it ? Can you post a photo ?
