Tearing HU apart for Boards - Android Head-Units

So mediatek 8127 trash.. Not rootable. Wouldn't keep the screen on unless I had otg hooked up. I tried everything. Anyways... I bought orange pi h3 and billion things for it; ATmega328P Nano V3 Controller Board for 3.2" OBD cluster project and tft 7". I bought a driver thinking that's all it was, but I just i'll have two 7" screens now. I bought;
----AUDIO---
900W DC-DC Boost Converter 8-60V to 10-120V 15A Step Up
TPA3116 D2 120W+120W Dual-channel
ATMEGA16U2 Board For Arduino Mega 2560 R3
LM1036 Tone Board Preamp Board Volume Treble Bass Amplifier Z2S8
(Havent bought yet) TDA7498 BTL 100W+100W High-power Digital Amplifier Board AMP With Radiator
--OBD2 cluster lcd k line gauges--
FTDI Basic Breakout 5V/3.3V Adjustable- Micro USB
3.5" tft (even thought I can't touch it.....)
k type thermocouple
--display--
It will be displaying mainly 1280x600? The tft that came with my dismantled board. I bought another driver and it has a 800
--Other stuff--
GPS- No just the anntena
It has wifi already
I have a BT board if it doesn't.. No clue.
Fm transmitter I have too.
Sooo I really don't know anything about rasp pi og pi arduino, but I do know 100$ double dins are trash. I am able to pull the fm transmitter and bt board off but that's it. I took 3 old laptops apart just to find one 40 pin monitor adapter..... but a "driver board"...... idk!
I guess I would really appreciate a smack in the head followed by a "none of that even works together"..
Ohh.. and I got 4 P1675 Punch 6.75" 3-Way Full-Range 440W speakers.. I think that's what i'm most excited about. All I was ever able to do with this double din I dismantled was sit in my room running it from a trickle charger trying everything to wipe it and get something worthwhile. So two questions.... Is there a pin diagram out there somewhere? Are they standard? All I know is it has an HP laptop kernel. 400mb mali something ur' other.. Mtk8127a. The board says "YLD-ANDROID-CORE-PCBV00". mediatek mt6323LGA 1644-AGTH. 70 pins only around the edges. NO markings for what.... Ohhh and the cover over the board says YLD-CORE-AD1616_MOO.
Second question With voltage boosters and amplifiers what else audio wise do I need concerning the board/module aspect.. Best method of transferring music that's playing from orange pi to, two TPA3116 D2 120W+120W Dual-channel's and the possible bridgable mono TDA7498 amp for my sub.... run wires... But from where? Point of origin... I feel like i'm missing a driver/board for audio or something. I've been looking into all of this for months, so sorry for not having a better idea, it's just like a candy store of 2$ 5000gig 8 channel yada yada out there. It's endless.....
Orange pi can flow with raspberry pi b+ for sure and most below i'd imagine and arduino touch screens and sensors couldn't care less. Does that sound right?
Thanks for any advice. Hopes this isn't in the wrong area. It is all being made into a headunit....
Ehhhh after looking into orange pi... The specs are there, but the support is like zero.... Glad it's so cheap to change my mind. I want nougat or oreo/rooted/cmXX/aosp anything flippin rooted. and not Kit Kat..... Seriously............ MHL one of my rooted phones into the mini hdmi or something like that..... Idk, but I just found out my options are pretty much if not only that of Kali linux. Super cool most of the time, but I don't forsee me sniffing packets from the prius at the red light...

Charging/Stereo Cable?

Just a quick question.
Is there a cable that allows you to charge the Kaiser/Tilt and also take the audio from the mini usb and have it go to a 1/8 in mini female? This would allow me to have my phone charge while being able to plug an audio cable to my car radio and listen to music while charging. Is something like this even possible?
I picked up one of these. It allows you to charge and use a regular 3.5mm headphone at the same time.
I considered this OEM version but went for the cheaper one linked above.

Thanks for this.
I just ordered one too. I've got the standard one -- but alas watching videos my device is dead in no time without charger input.

Brett,
Thank you. That is exactly what I was looking for.
Charging/Stereo Cable
Thanks just what I was looking for....I'm surprised that I didn't have to pay extra for the charger....from AT&T!
Question: Does any USB cable work with the Tilt?
Stop off at your local verizon store and pick up the OEM HTC headphone/usb adaptor cable for the Verizon XV6800. The adaptor is universal for the current generation HTC devices with 11 pin port. Its listed online, and should be available in most stores. Price is $19.99 +tax, which really isnt that bad for an OEM part. Even has the spiffy little HTC logo embossed on the handset end of the adaptor.
Heres the direct link, copy/paste it, youll get an error page, just click accessories and enter your zip code and click enter, then re-paste this in your address bar and hit enter, and the page will come up. No clue why it doesnt just open on the first try without a zip code since its online.
http://www.verizonwireless.com/b2c/store/accessoryPopup?item=accessoryMart&accessoryId=31462
Also, yes, any A to mini-A usb cable will connect your device to your pc.
Sorry I didn't see this sooner, but I got this one
It does ship from Hong Kong, so it takes a few weeks, but it's totally worth it.

Lets you charge, have a set of USB headphones or the classic headphone jack all at once.
I recommend this to everyone. $17 + around $6 shipping = Well spent $25.

When I had the mogul with sprint:, it came with that plug. When I sold it on ebay, I kept it.. They sent the wrong plug. It was supposed to just be the 2 usb plugs.

[Q] Motorola Mini USB to HDMI ? will defy support this ??

I'm unable to post the outside link so pls search this on google
"motorola 1080P HDMI CABLE (15FT)"
Saw this on motorola shop
can defy support this?????
pls Reply ASAP
It's not possible to use the Mini-USB as TV-out on your Defy. So the answer is no.
aww...is there any possible mod for cm7 and miui so that tis could work on defy?

as said before... no!
it`s not mini-usb it is micro-USB and it`s not possible to use it as TV out. Anyone who want`s TV out should have proper output jack. Devices that support that kind of cable have micro-USB and micro-HDMI port`s so it`s not the same port!!!!
To see what I`m talking about just look at the second picture od Atrix:

There are 2 kind` od jacks, micro-USB for data transfer and charging, and micro-HDMI for video output.
you're wrong. tv output through the usb port is possible, just look at the galaxy s2. but the defy doesnt support it. its chipset would, but its hardware-disabled... -.-

so you mean if we "unlock" the bootloader, then we can write custom drivers for this to make it work? like in the sgs2 using an mhl adapter? or even using 3.5mm to output AV like some nokias do?
OH man, if yes, i would be on the top of this world.
tv out is the thing that most important to me on the phone... I've had an N8 before my Defy, and I had used the tv function alot!
i was searching alot on the Internet for a tv-out solution for the deft, but came out with nothing...
I'm only using Defy beacuse I got it for free...
Try the green cirkel ico "Media Share" if you can, can test it myzelf because y dont have the wifi stick for my led-tv ,y read thats the way whit this phoon it can do so. Y now what you mis on the Defy, same here on my Nokia C7, **** symbian but some nice gadgets like tv from the headpfoon plug, special when gaming, super big screen here on 47" tv en nice to via usb on tv use it like a hard disk.
Sorry for the bad typing, ym Dutch and Eng. is dificult here for oldie (56)

Teclast X80H wifi fix

For those who feels that their Teclast X80H has weak wifi, I did the following to improve the connection.
My 2 weeks Teclast X80H wifi performance is much lower as compared to my other devices. Without line of sight, and sitting on another room at 10 m distance, I can't connect to the wifi at all.
Having inspired by the following video:
https://www.youtube.com/watch?v=G3j6rOp0lvY
I decided to open my X80H to look at the antenna configuration, and possibly do the same for the tablet.
Refer to the following picture:

Look at the top for the antenna assembly. I tested using digital multimeter, and found out that basically the ground and the antenna is shorted. Exactly like the youtube video I reference to..
Upon desoldering the ground, my wifi improves immediately.
Another thing, you will need to change the wifi settings from the windows device manager, to use only the 802.11 b/g and disable the n connections. Somehow the antenna / the wifi chip is not good enough for n connection.
Desolder the minus point?
Hello, I have a teclast X80 Pro. I would like to desolder the ground. I can see two soldering points on the tablet. One is minus and the other one is plus. Do I have to desolder the minus point?
Many thanks in advance!
With DC voltage, the negative rail is commonly called the ground. There is no earth like you have in AC voltage.

thank a lot,you solved my big problem .ty. :good:

Desolder meaning remove (un-attached) the wire from board, is it ?
Hello , I have the exactly same problem with my teclast x80 plus.
Can you only cut the wire, I afraid that the hot iron damage the board.
I'm sorry to bring this up but anyone has results on the solution presented on this thread?
I opened my Teclast and the antenna installation is pretty much the same as in the picture above. I tried to pull it off but it didn't come out and I don't have a solder iron to desolder it. As the user above asked, but remains unanswered, can I just cut the antenna wire close to the solder?
(fyi, by repositioning (not desolder) the wire inside the tablet I started having better reception. Now I can go to the first floor without loosing connection but still it is slower than my other devices)
Thank you.
Hi. I did the mod yesterday. Now I have a functional wifi
thanks a lot for the info!!
But I had some problems...
1- Pay attention when you open the tablet, because I forget to remove the microSD card and the reader was forced a little and now the spring doesn't work and the SD card is not fixed I have to repair it
2- I forced a litlle in the bottom of the tablet and 2 minos scratches were made in the screen. Now the touch bottom of the tablet doesn't work and I have to replace the digitizer (I've buyed a new one. only 6 euros)
Do you know the way to replace it? I don't want to broke nothing else
I replaceed the antenna for the one of an Onda soldering it and performance improved a lot.

Dasaita - Idrive Controller?

I can't post a directly link to it unfortunately.
Does anyone have any experience with this?
I fell down a rabbit hole of how to hack the factory BMW idrive controller with CAN messages to use it as an HID controller...seems like a lot of work and time to get that working with an Android head unit.
However if you take a look at this controller, it seems to have 3 wires.
12v, Ground and... a signal wire? Like a stepped resistor?
This would be a big shortcut in having a BMW like controller if it would work with other Android Head Units using the steering wheel control input.
What do you guys think?

It's hard to see but there's a fourth pin that's white. I'm guessing that it's usb for the reason that that's a repro controller made for the android i drive replacements
I would get one and try that but the price is too steep to tinker with.

I expect that the green wire will be the connection to the ibus. Rather than being resistive, it will be sending messages (short sequences of around 8 bytes) on the ibus which will be picked up by the appropriate module in the car.
I ordered one quite some time ago to play with. If I ever recieve it from China (it's been at least 3 months) I'll let you know how it works. I have Dasaita head units but I'll chop it up and see if it works as a typical wired remote on one of my other Android head units.

I am very interested in this project. My chinese idrive controller should have 5 pin and I would like to use with a tablet. I ordered it today so it should delivered in 2 months. Have you tried yours?

I've got mine today. It has a stm32f103c8t6 microcontroller on the board inside. I tried hooking up its cable to a USB port, but my computer did not recognize it as a USB device, unfortunately. More digging tomorrow...
p.s. I might have fried it by applying 12V to the red and black pins to see if it runs on 12V and maybe get the buttons to light up. hehe
12V would be fine to it, as the two voltage regulators on the board are designed to go up to 40V. Keep in mind the red and WHITE wire are power and ground. Not red/black like most rational people would think
However it's bad news.. It's not USB. It'd designed to communicate over the can bus and that's what the other two wires are hooked up to. A chip that translates CAN bus messages to something the STM32 microcontroller on the board can process. I'm going to try to write new firmware to the STM32 to make it talk over USB and see if that works.
However, this is not a plug and play solution for Android head units the way it arrives from Dasaita.

So what is your question?
I'm trying to hook it up to my Dell laptop it's a 15 i7 16 g ram 512 rom I'm sure it's more than capable but when I connect the laptop to the stereo through USB ports my laptop doesn't even show it connected is there a program I need or something to be able to do what I need to to root this stereo or atleast recalibrate the touch screen on the stereo through the laptop I'm newbie and am just now willing to sacrifice to learn it's kinda hard knowing something's are cheap if you screw up

Okay Steven, let's see if we can sort this out. Before you begin, you need to come to terms with that any modification of any Android, but particularly this one - requires intermediate knowledge of PC computers and Android devices. Any modification, if done incorrectly, might cause your head unit not to work anymore.
Your computer specs do not matter and have no impact on whether you can successfully connect and communicate with your head unit. The drivers however is a different story.
Please follow my video tutorial here that will help you to connect your head unit correctly, install the drivers and make a full backup. Enable English subtitles as they are more descriptive than some of the language I'm using in the video.
The video above will help you with all your questions so make sure to follow it. As for calibrating your head unit, most of this is done from Factory Settings in the head unit, not PC. Rooting an Android is only recommended if you really know what you're doing or at the very least has a good guide as a reference. Feel free to look at my guides in my signature.
If you are still within your warranty period, I would however suggest you return your head unit, just to be on the safe side.
