Hi all,
I have a CHT 9000, and the mini usb charge cable just wont charge it.
After inspection, I determined the source of the problem - damaged mini usb port pins, bent and loose, that cable wont even touch the pins to charge...
I need to know how to replace that mini usb charge port connector...
Thanks

Thankfully that is a part which is relatively easy to solder. Armed with a fine point soldering iron it's not too difficult at all. If I remember it has either 2 or 4 soldered anchor points and then of course the fine connections at the back end.
You may find a new port online or buy up a device that is being parted out.
For full functionality you need the 11 pin type (Not the 4 or 5 pin). See here:

This is my first post with links and info and stuff so please don't mind the bad formatting or other errors.
I bought a docking station a bit back and tore it down; I'm not very impressed but I'm sure we can make something of it.
Dock:
Connector and IR:
Connector - Top:
Connector - Bottom:
Mainboard - Top:
Mainboard - Bottom:
As you can see on this unit there isn't any HDMI however the board was made for it. Also of note is the HDMI pins on the ribbon cable.
I've checked and the nuvoTon (W78E052DFG) is an 8052 with 8KB flash and 256 bytes ram.
The audio portion seems to have a filter set on it however I don't believe it's amplified.
I have not been able to determine if there is or isn't USB on the ribbon cable or connector though there's no sign of it on the board.
Another point is I've switched to a custom rom and it no longer detects the dock. I noticed before switching that there is a service that watches for the dock and I'm guessing sends a signal to android to start the media app on dock. Virtuous XooM does not in any way detect connection.
Communication with the 8052 is through serial and the kernel source shows info about it. I haven't been able to find any reference to USB. if USB is present I'd expect it to be the pair near pin 30.
(All images taken with the A500 camera)
------- New info: (copied from later post)
This is the dock pinout as seen by the tablet (other devices may have different pins connected)
1-10 no connection
11 - unknown - traced to Q9 near IR connector on dock but unable to find past there (2v from tablet)
12 no connection
13 - audio connect of some sort - appears to be connected to left channel (after capacitor) through a 1k resistor
14 - Right audio - decoupled with 100uF
15 - Left audio - decoupled with 100uF like right channel
16 - Audio ground - not connected to main ground
17 no connection
18-20 +12V
21-30 HDMI - NO signals connected except GND at 21,24,27,30
31 - unknown - 3.3v from tablet
32 - TXD pin on 8052 through a level converter
33 - RXD pin on 8052 through a level converter
34 - unknown - 0v - 3.3v when dock unpowered but tablet connected so this may be a dock detection
35 - connected to 33 on tablet side
36 - connected to 32 on tablet side
37-40 no connection
These are all assumptions based on zebra cable layout so are quite probably wrong. They are also numbered based on the ribbon cable and I haven't made a conversion between ribbon cable and connector.
A voltage readings were done with an uncalibrated DMM on an oscilloscope (which seems to be .2v off or more). If i mark "from tablet" it's because it's not live when tablet not present and live even if power is disconnected from base.
1 case ground 0v
2-7 serial port(0v across)
8-20 HDMI
21unknown 3.3v from tablet
22 unknown 2v from tablet
23 unknown 2v from tablet
24-25 audio - audio even when nothing plugged in 0v
26 audio ground 0v
27 unknown 2v from tablet
28 unknown 0v (3.3v when dock unpowered but tablet docked)
30-35 12.0V
37 unknown 0v
38-40 gnd
Audio pins are correct but I can't tell which channel is which without finding a mp3 with audio only on one side. I would also trust the HDMI pins as ballanced pairs with shield between running directly to the HDMI portion of the board does seem rather proving.
None of the pins really look like USB as they should remain at 0v until a device is plugged in. I'll test connecting a 1500 ohm resister to 3.3v while monitoring the pin under test and see if I can find a USB connection attempt that way. If that doesn't work, finding pins with 15k ohm to GND would also indicate USB and I can try connecting a device to those.
Just recieved mine today from Amazon (they went on sale, so I figured I'd bite). No HDMI is disappointing, but not a dealbreaker for me.
Oddly enough, my biggest complaint is that it doesn't come with it's own power cable. I was hoping to leave the dock hooked up at home, and be able to pack the (INCREDIBLY SHORT) A500 power adapter in my bag for when I go out. Looks like it's back to eBay for another...
Excuse my off-topic mini rant. The teardown is appreciated. Curious if you ever did find anything with the USB pins.
I've read there are 2 versions of this docking station, one with HDMI and another without. It seems a lot of sellers are advertising the HDMI version but when people receive it, they get the non-HDMI version instead. Seems it's a hit or miss if you buy it online, probably safer to buy it from a brick & motar store so you can verify which version you're actually getting.
Sorry for off-topic too, just wanted to warn those that are thinking of getting this docking station
Nice tear-down btw.
Any idea what the part number for the connector itself is ? I am interested in a custom dock setup and all I am concerned about its power, however I need to find the mating connector to integrate into it.
Any info is appreciated!
Jeff
Quality of the photo surprised me !
So, any more info on this? I am putting an a100 in my dash, and I would like to use the dock connector at some point. For now I'll just run the power and audio through their ports I guess, but I would like to simplify the install at some point.
If these things suck so much, hopefully the price will drop soon, and I'll feel comfortable buying one to take apart for experimenting myself.
Thanks!

There aren't any identifiable markings however I think I found the right connector by checking some of the vendors who make 'em. I'm almost positive the connector is: JAE - DD2 Series
This means that there's also a cable variant of the dock side connector, cool eh?
I have not measured the connector to see if the dimensions are correct but the pitch, count, offset appearance and overall appearance are perfect matches. Even the slits cut into the top of the tablet-side connector match what's in the drawings. Still not a guarantee, but good enough for me to buy a couple to see if they match.
Here are the digikey parts:

Cable connector - $10.67 in singles

Perfect information. It seems that the 002 (HDMI) version has not been released in the US. It is not available on Acer's US site, nor do any of the US based online or B&M stores have it.
I'm definitely eager to see how this turns out. I'd love to know what each of the pins definitely is.
One assumes that the HDMI version is only required for the A100 series as the A500 already has full HDMI built in. Would the HDMI circuitry even work with an A500 in the dock? In fact, can you actually use the docks at all mismatched to the Iconia for which they were intended?

I wouldn't assume that at all... docs are designed to be left in place... so the purpose for the hdmi on the doc is so that you can keep it connected to your display all the time and not have to worry about plugging in the cable and the power... etc. where the doc satisfies both those needs. And I believe.. the hdmi doc for the a500 was available some time before the a100 was even released. (chk)

What's your confidence that pin 30-35 is actually 12V? Is is obvious (direct connection to the power port on the docking station)?
I will be buying one of those connectors (making a car dock) and want to be sure I won't be frying anything.
I will confirm if the connector fits and works in the A500 once I get the connector.

It's direct connectivity between +12v on the power jack and pins 30-35 on the zebra cable. These are not the same numbers on the connector itself.
If you look on SJ100278.pdf (digikey has link to drawing) the pin numbers are there. Note that the connector is wider at the top (notches near 21 and 40 on the side guides if that makes sence).
Pin 18,19 and 20 are +12V. There's no block of GND pins like I was expecting, instead GND is connected to 3, 6, 21, 24, 27, 30, and the connector shield. Due to the pattern of the gnd contacts, i'm guessing they're the shielding ones for HDMI. The connector is rated for 1A power per pin which means you need to use at minimum 2 of them.
I still haven't seen anything resembling USB and noticed that the tablet only uses a 20 pin zebra cable to the connector board (power included though they may pass GND through the case).
Now that I have my proper electronics desk at least partly set up, I can look further into the connector.

Every now and then you find things that make you just exclaim WTF at the top of your lungs.
The dock connector board located in the tablet does not appear to have HDMI signals on it. The zebra cable between it and the mainboard has 20 pins. 17-20 are +12V, 12-15 are GND. I'm having troubles doing continuity tests between any of the HDMI signal pairs and the other pins on the internal connector.
Bad news on the USB front, there is no 5V and all the USB pins internal to the tablet float at 0.067V disconnected and I don't see similar levels on any of the pins.
It's looking more and more like the dock was designed for a completely different product. Can someone over where the HDMI capable docks are available check their tablet internals and see if the connector board is any different. Alternatively can someone test one of the HDMI docks to see if it even works with their tablets.
I'm working through the tablet side right now, I'll take some pictures and document my findings in a little bit here.

That being said - anyone wana mod their tablets? I was thinking adding a tiny USB hub in where the USB cable runs and make a new dock connector that has USB on it (taking over for the stupid serial pins maybe). Would need a new series of docks (or mod boards for the docks)... maybe a silly idea though
----
Oh, also, is there anyone even interested in me reverse-engineering the serial protocol used for the IR control? I can probably do so with some time but it'll require me to reformat my tablet to factory as none of the other ones seem to support the dock.
:facepalm:. I bet they designed this port, initially, for their own proprietary means in a lab/repair environment, and said "Ya know, if we're gonna have this ugly port on the thing, may as well find something that the consumers would be able to use this for", thus coming up with the dock and only for syncing...
Acer UK store( http://store.acer.com/store/aceremea/en_GB/list/parentCategoryID.55934900/categoryID.56077100 ) claims that the HDMI version of the dock is only for the A100/A101 while the non-HDMI is only for A500/A501.
Power up tablet throught dock port
Anyone knows if it's possible to send a signal to power up (as if you push the power button) to power up the tablet?
I know that they have a powerbutton on the remote but i don't know how to do it to start it.
Thanks!
I used to have a Motorola Razr and my wife used to have a Droid 4. Each of us had a Nettop Device (Laptop Dock) that was made for the older Atrix. A few minutes with a small screwdriver and an Xacto knife adapted the docks for use with the Droids. We loved them, me especially. I used mine daily.
Now we have Note 3's and love them, but I sure do miss the use of my laptop dock. The dock has a male micro USB plug, which allows control of the dock's keyboard, track pad, and any peripherals connected to one of the two USB ports on the device. The dock also has a male micro HDMI, which goes to the display.
What would I need to connect my Note 3 to the dock? Any help would be greatly appreciated.
Thanks in advance,
Andrew
Hello guys, I'm trying to interface android tab with peripherals. Problem is, it is having only one micro USB port which is used for charging and otg/host, only one function is possible at a time .But I need to charge the tab and simultaneously transfer data to peripherals, say for example I need to use external mouse and charge the tab at same time.
So, is there any way to do it?
I know usb has 4 pins 5v,d+,d-,gnd. I thought to wire charging input power to tab pin 5v and gnd and pin D+,D-of tab to mouse D+, D- and giving external power supply to 5v and gnd pin of mouse.
Is this a right method? To charge and transfer the data at the same time?
Kindly help me. Suggest a better way to do it.
(mini & micro) USB connectors have 5 pins: Vbus, D-, D+, Id, Gnd.
For OTG, the Id pin is connected to Gnd.
It's like the old adage, "You can lead a horse to water, but you can't make him drink."
You can connect a peripheral to an OTG host and have it work fine.
You can then connect an external power supply across the Vbus and Gnd.
The problem is, how does your host device know that it can "drink"?
There are basically two ways.
If the host detects power on its input before it switches into OTG host mode it may continue to charge.
If the host is in OTG host mode, device-specific commands to the charging circuits may convince it to charge.
There may also be non-standard Id resistor values for signalling host & charge for some devices.
I think your mileage would vary very much depending on what devices your using. AOS was not meant to deal with people hacking on the USB port, and probably the code to implement those features depend on your HW/FW.
If its a Samsung, you can play with some resistor values like these:
http://forum.xda-developers.com/showpost.php?p=25532839&postcount=2
I think the USB "CarKit" specifications should allow you both to charge and "connect" in some way.
A more easy solution would be to use a BlueTooth mouse and keep charging as usual.
I would like to share with you my setup which is like a dream come true. I have always imagined that one day I'll have single device that I will use throughout the whole day and now it finally is possible.
I bought an opened box HP Elite X3 Lap Dock of Ebay for 230 AUD in a pristine condition for my Galaxy Note 10+ (European, Exynos). Affter I have received it I had some trouble to connect my phone to the Lap Dock - the original HP cable was missing and the one from Samsung did not work. I finally figured it out - It has to be a USB C cable that will allow video transmission, quick data and power transfer - to sum up it has to be at least USB 3.1 Gen 1 that provides 5 Gb/s, 5V, 3A (Gen 2 provides 10 Gb/s). I bought https://www.amazon.de/gp/product/B01GGKYT7M/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1 and viola it works!
It is almost a perfect solution - I have been able to switch from Windows laptop instantly, I have prepared a whole lecture with PowerPoint on this setup, I use it from time to time for gaming (love the PSP games and bluetooth controller). All is extremely compact, premium made and useful. The whole set combines: Galaxy Note 10+, HP Elite X3 Lap Dock, Amazon USB C cable, 8Bitdo, Samsung 45Watt Charger, and couple of extras like additional HDMI cable with micro HDMI adapter, USB C to A cable, USB C hub with HDMI, 2 x USB and USB C sockets and foldable bluetooth keyboard with touchpad. All of these fit well in a 11 inch Apple Macbook Air neoprene bag
Connecting the HP Lapdock to the TV with HDMI (using HDMI to Micro-HDMI adapter) and then connecting phone wirelessly with it allows to display on TVs without Miracast.
In order to get regular size font while using DEX I am utilizing MacroDroid macros: Receive Notification DEX App - Change system font to 1.2 and Remove Notification DEX App - Change system font to 0.8 (my default)
The known issues are:
1. Lap Docks speakers does not work - I had to change in settings of DEX and in Developer Settings not to route sound via USB and now when connected sound is played from the phone
2. Touchpad buttons are not recognized - it works perfect other than that (gestures, zooming, scrolling, two fingers for right button)
UPDATE
Audio via lapdock speakers works! - in order to make it work just plug in the phone to the lapdock without turning it on and then turn it on by holding battery button and power button simultaneously for 10 seconds until it boots. When its on in volume panel chose play via display device and enjoy B&O sound.
There is a bad news too - after updating to Android 10 the touchpad is practically unusable - they have change the way it operates and now it moves incredibly fast up and down an extremely slow from left to right - the only option is to use the phone as touchpad which luckily is very good.

Updated, matured setup:
I can't get my Aussie exynos to work unfortunately.
You have to turn of lapdock first, give it a 10 sec after it has booted than connect it with a usb c 3.1 gen 2 cable (a short one, cables longer than 1 meter seems mot to work) and it should be fine. I am using a 50 cm UGreen cable, sometimes it is required to hard reset the lapdock when it does not pair properly by holding the power button for 10 sec.
An Update:
Finally audio via lapdock speakers works - in order to make it work just plug in the phone to the lapdock without turning it on and then turn it on by holding battery button and power button simultaneously for 10 seconds until it boots. When its on in volume panel chose play via display device and enjoy B&O sound.

Maybe we can send a request to Samsung to fix the problem with the touchpad because we are many users with it.
Anyone with the tab s (5e or 6). Can check if having same problem?
Thanks
Can you please check underneath your Lap Dock what the model number is?
E.g. V8H07UT#ABA or Y1M47EA#ABH, etc.
I am having the latter also with a European Exynos Note 10+ and I can't it to fully connect (no display).
Thanks!
I bought the HP Lap Dock V8H07UT#ABA for my Note 10+ Exynos (Portugal) and was never able to have it work. I bought many different cables but didn't change a thing. The same cables used to connect my Tab S4 (Snapdragon) to the HP Lap Dock worked flawlessly.
So you are very lucky to have a working setup!
Ok, I got seriously lucky.
Found the mainboard of the V8H07UT#ABA online, and it arrived today.
Replaced the mainboard of my Y1M47EA#ABH with it, and I now have a working Lap Dock with my European Exynos Note 10+. Happy camper here!

What kind of USB-C cable are you using? The one that comes with the Lap Dock or another brand? Is Developer Mode enabled ? Thanks.
Currently I am using a cable from Ugreen witch has a proper length and is very well made https://m.pl.aliexpress.com/item/32...detail&spm=a2g0o.cart.0.0.307e3c00rTzEtg&mp=1
It also fits in nicely with a magnetic usb c adapter that I have attached to my lapdock https://www.aliexpress.com/item/32985884761.html?spm=a2g0s.9042311.0.0.27424c4dZXuZyS
Just now I have found one strange thing - I have change the cable I used with and older one which was working fine and now it did not - what did fix this issue was switching the ends of the cable the end that was going into lapdock went to phone and vice versa. I know it should not make any difference since these cables are reversible but it did mabye that will help somebody.
Well, now we got wireless dex!
Upgraded set, now based on Nexdock Touch - https://www.reddit.com/r/SamsungDex/comments/jp7940/my_perfect_mobile_dex_setup_completed/
I am trying to make the Lapdock work with LG V30 - wirelessly I have succeded to make connection as a secondary screen - so the phone screen is projected to the lapdock.
Now I want to be able to use the keyboard and touch pad: I use a ugreen PD100W cable and I can get the notification on the phone that external kb, mouse and sound is detected. no image goes to the lapdock screen. Sound does though on both LG and HP elite x3.
I think the cable might be to blame...
I tried then to connect wirelessly - I can get the image on the lapdock, the kb even works, but I cannot open apps, no mouse is detected (touchpad does not work) Sound too.
Do I need a cable that says 4k on it?
lapdock 1 P/N - Y4T07AA£ABA
lapdock 2 P/N - Y1M47EA£ABU
I bought one then another hoping to make it work, but they have similar behauviour - when connectd via cable, the screen go dark blank, but I can see that it actually works, just a black picture is displayed
Also, anyone knows what is the difference between lapdock models above?
