Bluetooth remote display project

I'm beginning a new project and have most of the implementation process done. Basically the part I need help with involves pulling text from my HTC Touch Pro, and transmitting the text via bluetooth to a digital panel similiar to the one below:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It can be more fancy, but doesn't have to be. The main goals are that it displays text, can receive the text via bluetooth, and isn't bulky (from front to back, height and width don't matter). Running on batteries is a plus as I'd prefer the project be completely wireless.
I'd much rather it be a self contained unit, but I don't mind doing a little dirty work if it means wiring a bluetooth adapter to the screen. I have no knowledge on how the bluetooth adapter would translate the textual data to the screen though, so I may need help with that too.
Thanks for any and all help!

[Q] Connector, male to female

Ahoy!
I am looking for a way to use HDMI output AND a keyboard at the same time.
When i see it correct, the keyboard dock has an output of the same size as the tab itself. Do you know where to get or how to make a connector that will connect the female output on the keyboard with the male input of the hdmi, chargin, etc. dock?
Maybe i would have to take away the power of the hdmi dock of course...
see pics attached:

}

The local store told me the input on the keyboard is for charging!? Can somebody please confirm/deny this? I think that can't be true. It's the most stupid place for the main cable. The cable would always bend to a sharp angle.

[WIP] Wireless Charging on IncS

I am planning to install wireless charging in IncS.
I would need some advice from experts in order to move forward.
On going through various forums on internet, i came across a small difference between the HTC Droid Incredible 2(Which supports wireless charging) and IncS.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
There are 4 small contact points on both the motherboards(Marked and circled in the pic). But on INcredible 2 there is a small plate soldered on those. Whereas, on INcS there is no such thing. I mean there is no way a Qi compatible charger receiver can touch the motherboard.
My question now is that should I get this thing soldered on IncS motherboard or do I need to do something else also?

thanks all

This cable that you have on image, is typical microUSB/MiniUSB video cable for older cameras, not phones. I think I have somewhere such cable that I got with old camera.
Also I dont know any mobile device that send analog signal via such cable, only cameras, chinese portable gamestations, some mp4 players and few other devices, but not phones that use digital MHL/microHMDI standard

thanks a lot

[REPAIR] Need help identifying a part + soldering

Hi,
I've a defective Google Pixel 4XL lying around I'd like to fix, however I can't figure out what what the part bordered in red is supposed to be. Anyone got a clue? I can't tell if it's a a capacitor or resistor and the value it's got. Tried to see if there are schematics for the motherboard, but so far no luck.
As for the part bordered in green: I know that's where the female connector for the battery (FPC) belongs. Would soldering it back with a good soldering iron be possible? Any clue where I can order these for cheap?
