Strange RK3188 board, drivers problem. - Android Q&A, Help & Troubleshooting

Hello,
I'm working in Digital Signage company. We bought ultra-wide displays (1366x70, 19:1) with android board. The problem is that we want to install own software on this screens but display shows only 70px of top side of android. I think that LCD controller is set on 1366x768.
I can't connect to board via external usb ports but there is two USBs on board (OTG and USB1). I made a cable for connectors but Windows can't recognize this device.
Could anyone tell me is that some way to get to this players?

Thank you!
You're in the HP Touchpad forums. You'll have better luck in the forums for your specific device.

who works in the unbrick ?

Hello community.
Anyone working on the unbrick this device?
The other day I went up a picture where you can see a semiconductor, which would block the entry into the bootloader with Fast-Boot Cable

Just the Standard USB Circuitry...

That chip is probably not anything as nefarious as you're speculating... I believe it's just the standard USB EMI filter and line termination circuitry, similar to the STF202 device. Here's its spec sheet:

FYI...

Playstation Controller to USB Adaptor

I have the following adaptor:

"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It works fine with my phone (Galaxy S3 GT-I9300)
But I cannot get it to work with my Android media player (Minix NEO X8-H Plus)
I'm looking for any help to get the adaptor working on my media player.
While I wait for a reply I've been trying to resolve this myself.
I've tried chainfire's USB Host Diagnostic on both my phone and the media player, both gave the same result that they support USB Host:
View attachment 3263609
View attachment 3263610
Is there any other software that can diagnose/fix the issue?
Alternatively is there any other way of connecting 2 controllers to an android device that I can try?

Composite (RCA) Video/Audio Output from Mobile

I just bought a Nissan GT-R and I wound up getting a nice AV input added to the mix on the car. The input unfortunately is an RCA connection (analog SD Yellow/White/Red variety). I'd like to be able to mirror the phone's output onto the screen using this input. Is there a cable that allows this to be easily done on an android phone?
Current daily phone is a stock, un-rooted, AT&T Galaxy Note 5.
Before anyone asks here's the ride and unlike the phone this thing isn't stock. :silly:
