OTG and MHL working together? - General Questions and Answers

My xperia z1 unfortunately fell on the floor that the display is kinda dead now. When I charge it, the notification light still lights up and turns to green when fully charged. The display however, only leaves a white straight line when I turn it on and I think the touch is also dead.
All I want to do now is to extract the data from the phone, but the USB debugging is not turned on and the phone has a password protected lock screen.
As I don't really wanna fix it or use Dr fone(if not necessary), I want to buy a micro USB to HDMI/usb adaptor to connect the phone to an external display and a mouse to control it, but I just don't know whether otg mouse and the hdmi can work properly when connected simultaneously.
Please help or please give me other suggestions.

[Q] Sensation won't start

So I've got a Sensation phone that won't start. Bootloader menu can't be accessed as well. When I plug it in, the orange LED lights up, stays on for about 3 seconds, then goes off for about a second and finally lights up again and stays on permanently. Tried with a different battery - no luck. When I connect it to the pc via micro usb cable, the computer recognizes the phone (installs drivers for htc sensation). And there's something more - when I connect the charger in a completely dark room, the display backlight becomes visible. The screen doesn't light up but it also doesn't remain completely dark. It's like the screen is on but completely black.
So what can I do? Thought that the power button might be defective, so I removed the black tape over the button and short circuited the two small pins on top of the button. It didn't work. I can't fire it up through abd, because usb debugging is off. So do I have any options beside selling it on ebay or giving to a service technician?

Thanks for the suggestion
I haven't tried this solution yet because the problem does't seem to be a QHSUSB_DLOAD issue.
Upon connection with pc it identifies with hardware id USB\VID_0BB4&PID_0FF9&REV_0228 as a mass storage device...

[Q] Issues with Tablet Connected to Keyboard Dock

When tablet is connected to the keyboard dock it will not allow the screen to be turned on via the power button on the tablet (top left.)
Also it seems that some times when tablet is connected to the keyboard it sends it into the reboot.
There is no damage the ports, charging works fine in the tablet, and when connected to the tablet the keyboards charges the tablet and shows the battery level of both devices. Checked for dust or anything else in the ports, but all are clean, blew them out with AirDuster just to be sure.

Any way to disable the "auto screen on" when plugging in USB?

Is there a mod for this somewhere? I'd love to stop the screen from coming on when plugging it in to my PC, my car for Android Auto, etc.
Even if you find a method, I'd recommend keeping it enabled, as it is currently the only way to know that power is flowing to the device. Without a charging LED or activation AOD, the phone gives you no indication of its status and could leave you frustrated the one time you plug it in and the other end of the cable isn't properly inserted.

I've had it on my phones in the past and LOVED it. I don't really need any visual indication of charging, I've never had any problems with plugging it in and it just charging.

Xperia 1 II issue

Hey,
I bought the Sony Xperia 1 II today, charged, set it up, moved all the stuff from my old phone to it, all went perfect.
Then I decided I'd move music onto it, this is where the issues began.. I plugged the cable into the back of my PC but neither the phone or the PC would recognize eachother.. After some fiddling, plugging and unplugging, I finally managed to put the phone into file transfer mode.
After I was done with the transfers, I unplugged the USB cable and the phone turned off.. Now I have to have it plugged to the charger or I have to hold the power button to use it.
Any ideas? My guess is that it's stuck in some USB limbo. I've been wanting to clear the cache partition but I have no idea how to get to it on this phone.. Also not really feeling like doing a factory reset since it'd mean sitting through all the app setups, logins and jazz.
Thanks.
tl;dr
Phone turns off when you unplug USB/charger, works perfectly fine when plugged in or when you hold down the power button (it boots and lets you use the screen like normal, just a bit awkward ofc).
