In the link it says you couldnt get the usb line working but it seems like in the pic (in your post) that you were able to get it working, so what was the problem?
[Samsung Galaxy Nexus] knyghtryda:
The USB charging works fine, but the GN (like some other Samsung phones) has the ability to use the USB data pins for audio line out. This should be triggered by being in dock mode, then you activate it in the dock settings. Unfortunately I can't seem to activate it. I'm suspecting its a software issue, but I'll have to test more resistors (gonna try 1K and 619K) across the ID pin in order to make sure of that.
[Samsung Galaxy Nexus] jonnyg1097:
Oh good, I was looking for a USB charging with a dock like this and now I may consider getting it and making the mod since it worked out so well.
[Samsung Galaxy Nexus] xformulax:
modded my captivate dock tonight... didnt cut off a chunk of the front face like that one though... turned out pretty nice, removed the LED at the bottom because that always annoyed me on my night stand.

i was hoping to modify it so that it would fit with my case, no such luck.... fits fine with my extended battery though.

not sure if i'll want to take my case off every night so I might just sell this if someone wants it.
[Samsung Galaxy Nexus] knyghtryda:
The reason I cut that chunk off was to fit the micro USB plug a little farther forward so that I could use it with a case. when I was test fitting I found that without a case the plug would fit fine behind the plastic, which makes sense since the plastic I cut was just slightly thinker than the TPU of my case.
[Samsung Galaxy Nexus] xformulax:
i was thinking about doing that, cutting it cleanly and then gluing the piece back on to kind of cover it up, but i dont have any cutting discs for my dremel (couldnt even find my damn dremel)

i actually made the hole for the plug relocation with a soldering iron.

I also looked at your pics, but did NOT read, so of course I tried prying the whole face up and marred it a bit before pulling the back panel and using the screws.
[Samsung Galaxy Nexus] psycho2097:
My captivate was pretty much the same size as my GN, thicknes wise, how much modification did u do? can i fit it in the cappy dock withot significant effort? I am not very good at cutting & filing and soldering lol...

And does your audio out thru usb work?
[Samsung Galaxy Nexus] knyghtryda:
Please read the tutorial, it explains all of it :)
[Samsung Galaxy Nexus] knyghtryda:
Lol I did some good damage to my dock as well doing the same thing you did, hence me writing it up so people can avoid my stupidity :p.

When I did the cuts I just used some wire cutters instead of a dremel. It would have taken longer to set up the dremel than it took to snip a couple times and cut that piece off.
[Samsung Galaxy Nexus] psycho2097:
Hell no...I am so not doing all that crap.that too for no audio out.

Well I was just wondering if there is an easy way out.you used the fascinate dock, would the captivate dock be easier to mod?

Sent from my Galaxy Nexus
[Samsung Galaxy Nexus] knyghtryda:
every single samsung SGS generation dock is pretty much constructed the same way. They also use pretty much the same internals. Maybe SGS2 docks are different, but I haven't torn one apart to find out (anyone know where I can get an SGS2 dock for cheap?). The exceptions to this are the "multimedia" docks which have HDMI built in. Those simply roll in a MHL adapter, or take micro HDMI from the phone (like in the case of the Droid Charge).
[Samsung Galaxy Nexus] Gahh Its Lee:
Oh I bought mine already in was hoping for audio out... Too bad I suppose. If anyone figure out anyway to get it working post lol
[Samsung Galaxy Nexus] xformulax:
audio out does not work, you don't need to solder, you basicallly take it apart, then cut a hole where the USB jack should go above the captivate location, move the plug and glue it in.

all of the galaxy S docks are the same functionally, just slightly different shapes where the phone sits because the captivate and fascinate are shaped differently... vibrant should be pretty similar to fascinate.

lol, epic 4g is thicker, and the charge port is in the center like ours... might be the best to experiment with. (i used the captivate dock because I already had one)
[Samsung Galaxy Nexus] jaymax97:
can i just take the plastic case from the dock and swap in a mhl adapter so it will be a dock that i can plug into my tv or will i not have room
[Samsung Galaxy Nexus] knyghtryda:
There's plenty of room, but you'll have to resolder some stuff as you'll need to right angle micro USB plug that comes with the dock. The standard straight plug from the MHL adapter USB plug will not fit correctly.
[Samsung Galaxy Nexus] psycho2097:
can sum1 with an epic 4g pls confirm that it fits with the nexus? bcz it seems that thickness wise, and usb port location wise, it should fit.
[Samsung Galaxy Nexus] knyghtryda:
Take a look at this:

http://phone-size.com/?s=3%2C50

From the sizing it looks like it'll be a bit loose, but should work fine.
[Samsung Galaxy Nexus] psycho2097:
No i was thinking about the epic 4g, the original sgs one. altho this is a quite decent alternativ, the problem being that i cant find any cheap docks for the gs2 epic4g touch. Epic 4g docks, on the contrary are just 10$.
[Samsung Galaxy Nexus] push2flush:
I bought one, cut the appropriate hole, but the wiring doesn't seem to charge my phone for some reason, anyone else have that issue or did I just get a bad egg?
[Samsung Galaxy Nexus] quick_:
Is it possible you cut/damaged one of the wires going to the usb jack inside the dock?

Ordered one as well... can't go wrong for less than $6!

Also for those wanting audio, if you can live with the lesser quality of bluetooth, try to find some Bluetooth adapter that either has built in speakers or an output on it for audio output to your speakers. Then setup tasker to automatically turn on bluetooth once the phone hits "docked mode".

Luckily I have a blackberry stereo gateway that i have out of sight that outputs to my speakers so I will just use that for audio out.

Thanks OP for your guide btw... looking forward to trying this out.
[Samsung Galaxy Nexus] djras111:
I also have no charging on my GNex with this dock. My previous phone IS a Fascinate and before I tore it apart I made sure it did actually work with the Fascinate and was happy. It both charged the phone and played audio out the headphone jack. The phone also went into desk dock when first installed.

After dismantling it and attaching it to the GNex, the LED on the unit came on, but the phone saw no charging (both with a cable to computer or wall charger). The micro USB plug from the dock is very loose (for ease of connecting the phone I guess). I wonder if that could be the issue. I will put a meter on things later to see what is going where.
[Samsung Galaxy Nexus] push2flush:
same thing here, light comes on when the phone is plugged in, but no response on the phone at all.
[Samsung Galaxy Nexus] jonnyg1097:
Nevermind post here
[Samsung Galaxy Nexus] Gahh Its Lee:
How is everyone getting the back off? I cant seem to pry mine
[Samsung Galaxy Nexus] ellisz:
I did this mod and it is working fine. One night I think I did not push it in all the way and it did not charge but otherwise, it has been fine. I tried to making it work with the TPU case but alas, it was not possible. Should have just learned from the OP ;)

The back was a PITA. Just get a small flathead screwdriver and work it into a corner. I swore it seemed like there were screws holding the front corners as well but there are not. You just have to pop the tabs holding it in place.

I am considering trying to take a universal car dock and superglue a charger cord in place. Not sure how it would look though. Most of them have the cushions on them and I figure I could slot them to allow the phone and case to "slide" in. Would have to use some abs or something to mount the plug and glue it to the braces that hold the bottom.
[Samsung Galaxy Nexus] Gahh Its Lee:
Did this mod today works fine. Took literally 10 minutes. 8 of which were getting it apart
[Samsung Galaxy Nexus] djras111:
The back is held by plastic tabs (6 or 8) the front also is held by tabs, the bottom ones broke when I pried the front off.
[Samsung Galaxy Nexus] knyghtryda:
I used a small screwdriver and put it between the back panel and the body then gave it a good couple hits with a blunt object. It actually did less damage that way than trying to slowly pry it off. Once you can get your screwdriver behind the panel then just slowly work your way around undoing the tabs.
[Samsung Galaxy Nexus] ellisz:
I spoke to soon I guess ... I have not charged the last 2 nights while on the dock. The plug is off a bit but it is going in and making a connection. It must have to be pretty exact?
[Samsung Galaxy Nexus] knyghtryda:
Did you eyeball the plug location or actually have the phone in place and plugged when you glued everything down? The plug is relatively forgiving but I found that you don't have a lot of leeway in terms of mounting space, especially forward and backward. If your forward/back distances aren't correct then you could have contact issues. I would recommend everyone turn on their dock sounds so that you know when the phone is actually docked and charging.
[Samsung Galaxy Nexus] ellisz:
I did line it up but it apparently shifted down a bit. It is a bit angled. I can slide it in fairly easy though. I switched to the circle battery so I can see the charging icon better than the 1% mod on the rectangle battery icon. I get the dock sound when I pull it off the dock but not when I put it on. It does switch to the clock when I put it on the dock though.

I will test is again later.

Thanks
[Samsung Galaxy Nexus] sneakysolidbake:
I hacked mine apart yesterday and super glued it today after deciding I was happy with the positioning.

It fits rather well and is easy to use with any combination of battery(reg or ext), battery cover(reg or ext), or rev3 diztronic case(matte black or high gloss black).

I actually tore out the wires going to the dock light by accident during disassembly and didn't bother to reconnect it. So far so good.
[Samsung Galaxy Nexus] Gahh Its Lee:
How did everyone glue there's? I ended up cutting off the entire part from the original hole for the plug up.
[Samsung Galaxy Nexus] sneakysolidbake:
My exact method was using some small wire cutters to cut a separate slot and I mostly aimed for the same spot as you see in the how to. I then got around to charging my dremel battery (sad I don't have a wired one, I know) and cleaned it up some. On the middle portion of the dock I cut some small bits off the upper left corner so the USB plug can sit in proper alignment. I set my lte gnex in diztronic tpu case on the dock, plugged it in and then super glued it. Waited a while then slowly pulled the phone straight out and added a little more superglue.

Works perfect besides that its usb charging but I like it for what it is.
[Samsung Galaxy Nexus] quick_:
Got mine yesterday, however I have the same issue as a few others, where it does not charge the phone at all, seems dead, no wires are loose or damaged....

I did cut off the led wires, I will try to reattach it and see if it makes any difference...

Anyone who had no charge from it figure out the problem??

EDIT: reattached LED wires, and same issue as other LED lights up but not charging phone at all... :(

Also there is an individual piece of plastic that has a thin metal piece on it about 1/8" by 3/4" long, that was originally attached to the the charging piece inside the dock (the one that connects to the phone). I assumed this piece is not needed, is it??
[Samsung Galaxy Nexus] rotus8:
I bought three of these for playing around with, they are cheap enough, and all three have the problem of not charging the phone. I discovered that if I removed the ID resistor, they all charge. The OP stated that the ID resistor should be 365K ohms and mine all measured about 330K. I put a 365K resistor in one dock and it still charges, but when I put 365 in another dock it didn't!

Also, none of the docks put the home screen in landscape mode.

I will play around with different ID resistor values this evening and let you know what I find.

(First post on the forum - I hope you find it useful)
[Samsung Galaxy Nexus] quick_:
Thanks for your reply.

So if I detach the ID cable going to the resistor it will charge? Or does it have to be replaced with a 365k one?. (sorry im not very knowledgeable with electrical circuits etc..)

EDIT: Yes it does!! Awesome!

I was about to just glue a regular microusb charger and bypass the entire docks electronics lol... if I can simply cut this wire and it will work that would be great.

Also have the same issue with it not putting it into dock mode btw...

Maybe its only Verizon Galaxy Nexus that works with this?? What model do you have? (I have the GSM)

Thanks!
[Samsung Galaxy Nexus] rotus8:
I believe if you detach the wire for the ID that goes to the phone connector, it will charge. However, some value of ID resistor is needed to convince it to go into dock mode, so if you want that, you will have to replace the resistor. Replacing the resistor is a pain because it is a very small surface mount component.

It will be a few hours before I get home to try other resistor values, but maybe someone else will chime in with some more info on the value. Most valuable would be for someone with dock mode working to measure the value and let us know.
[Samsung Galaxy Nexus] neotekz:
when you were doing this mod do you think would be possible to make the mirco usb stick out a bit further to fit the GN with a case?
[Samsung Galaxy Nexus] knyghtryda:
I have a case on mine and it fits fine. What I did to make sure it fit was I had the phone plugged in when I was gluing down the plug. That way I know that in the docked position the plug would fit correctly.
[Samsung Galaxy Nexus] ellisz:
I am confused. I am going to remount my plug but do I need to do something with the board /resistor? Mine will go into desktop mode just fine. The light comes on the dock and I get a charging icon on the phone just like if I have it plugged in normally. Only thing is that it does not charge on the dock. It will gain a couple percent over night.

I took it all apart and plugged it in loose. Seems to be charging just fine ... I can believe it is that particular. It was not that far off.
[Samsung Galaxy Nexus] rotus8:
I have done a lot of experimenting with this setup and the good news is you can make it go into AC charging mode. On the little board inside, you need to short the D+ and D- pins together where the pigtail attaches. Then when it charges it will go into AC mode. This completely disables the ability to use the earphone jack, but I don't think it will ever work on our phones anyway.

The next is that some docks don't charge. I found that if you remove the resistor R8 on the board it will charge. An alternative is to cut the White wire going to the pigtail connector. But be careful, if you do this and it used to go into dock landscape mode, that function won't work any more.

Now the part where I am stuck:mad:. The R8 resistor connects the ID pin to ground, indicating to the phone something about the dock. I found four ranges of resistor (in addition to infinite) that turn on charging. However, on my phone it never goes into dock landscape mode.

My phone is a stock unrooted locked Verison CDMA. Can as many of you as possible who have done this tell me if the dock mode works or no, and what version phone and OS you are running. Maybe we can correlate something that will lead to the solution.

In case you care, the resistor ranges that work for charging for me are: 195K-220K, 245K-275K, 290K-325K, & 420K-479K, and infinite.

One final observation - there is no connection to the D+ and D- pins on the charger jack, so this dock cannot be used with a download cable connected to a computer. It should charge, but there will be no data connection. If you do the AC charge mode mod, it is possible you will overload a computer USB port, but most will be fine.
[Samsung Galaxy Nexus] knyghtryda:
Most of my research came from here:

http://xdaforums.com/showthread.php?t=820275

This is obviously for the galaxy s but Samsung seems to be pretty consistent with this stuff, as they should be since the galaxy s, galaxy s2, and galaxy nexus use the same USB chip (fsa9480). Well, I'm pretty sure the GN does anyway, cuz every spec sheet I've read online says it does http://www.mobiletechworld.com/2011/10/20/whats-inside-the-samsung-galaxy-nexus/. With this chip, tying the D+ and D- will result in AC mode, while anything else get USB mode. I haven't played with the various galaxy s resistor values yet, but try some of them and see if you can get car mode or something. Something I noticed when digging through some of the GN kernel source code was that it was missing the chip drivers. Maybe they're located somewhere else, but they're definitely not in the same place as any of the galaxy S phones (drivers/usb/gadget). Then again the galaxy S drivers seem to be tied pretty tightly with the processor so I dunno what the deal is. As you can tell, I'm not a kernel dev :)

edit:

Here's another tutorial relating to a galaxy s2 that may help some people

[Samsung Galaxy Nexus] ellisz:
I guess mine is one that does not charge. It will gain a little but is slower than normal. So if I cut the white wire on the usb cable this will get it to charge in AC mode? I have no problem manually putting the phone in dock mode. It does do it by itself now.
[Samsung Galaxy Nexus] rotus8:
If yours does go into dock mode by itself, can you please tell me the specifics of the phone?

To get it to charge in AC mode, you need to solder a short across the D+ and D- wires on the pigtail connection to the PC board inside the dock. You don't need to cut the wire if it is charging at all now.
[Samsung Galaxy Nexus] ellisz:
I have soldered wires but have not done much on boards. Do I take a short piece of wire and solder one end to the D+ and one to the D-? Sorry for the newb question.

I am rooted with AOKP M3 and Franko 13.1 kernel.
[Samsung Galaxy Nexus] rotus8:
Are you GSM or Verizon?

You could try to put a big blob of solder between the pins, but using a little piece of wire is more certain. It is a totally uncritical signal so as long as they are connected it doesn't matter how you do it. You could even unsolder one wire and solder it to the other, or even cut both wires, strip and solder together; they don't need to be connected to the board. This stuff is pretty tiny, you need a small iron and use care not to melt anything you don't intend.
[Samsung Galaxy Nexus] ellisz:
I am on Verizon.

I only have a standard soldering iron. I guess I will pull the board out a look at it again.

edit - Looks like just putting a dab of solder on it might work since they are right next to each other. I might be able to solder this. Is there a way to test it afterwards? Can I put a meter on it to test for voltage or are these pins really not a big deal on the power side of things?

Thanks
[Samsung Galaxy Nexus] rotus8:
Just look at it carefully to be sure you haven't got solder in the wrong place. Before assembling it, plug it in and check to see if you are on AC charge.
[Samsung Galaxy Nexus] ellisz:
Mine has never said I was on USB charge like it does when I plug into my PC. It just charges really slow. I placed a bit of solder between the two contacts. The first attempt failed as the solder bead fell off when I snapped the back plate back on. I re-did it but not sure got a good connection. It works but I still get put into dock mode when I mount it.

I will put it on tonight and see what happens. Last night I was at 50-50% and woke up at 85%. This was 7 hours or so.
[Samsung Galaxy Nexus] rotus8:
For those of you with problems getting into desk dock mode, I found this contribution from madmack: http://xdaforums.com/showthread.php?t=1412752

It allows auto rotation of your home screen, or locking it, plus it can be activated by tasker. Solved my last issue with this dock.
[Samsung Galaxy Nexus] quick_:
After cutting the id wire I was able to get mine to charge. It says USB mode charging, but that's a good thing really cause it will charge at a slower rate which I read somewhere will in turn give you longer battery life on a charge due to the slower charging...

I was never able to get it to sense dock mode when plugging it into the dock so what I did was setup a tasker profile with the following conditions:

When USB charging is detected

During the time of day 10pm to 9am

When no headset is plugged in (so it doesn't activate in my car)

Once those conditions are met:

It turns on Bluetooth

Connects to my blackberry Bluetooth stereo gateway (which is connected to speakers)

Loads the Clock App

Once disconnected:

Kills the clock app (using root)

Anyway I have big problem now though!! :( From the process of removing the phone from the dock it now has loosened my micro USB port on my phone. It's first noticable when you put it in the dock it will wiggle up and down on the opposite end of where the connection is significantly. Also when you plug a regular micro USB cable into the phone it wiggles side-to-side about 1/8th of an inch at least either way. Now I am worried that is will slowly break the port at the connection between the port and the motherboard/chip. I am assuming its like repeatedly bending a piece of metal which it eventually fatigue and snap.

Does anyone else have this loose micro USB port, and can anyone confirm if its actually the port that is wiggling or is it just the cable end wiggling inside the micro possibly widened/stretched port.

I have no warranty since I imported it, and I am really annoyed that Samsung is dragging the release of the pogo pin docks!!

FYI I have a TPU case on my GSM Galaxy Nexus, and I had it on and plugged into the phone when the USB port was glued to its final placement in the dock.
[Samsung Galaxy Nexus] ellisz:
I ended up soldering a small wire on the D1 & D2 and it is now charging. I still don't think it is as fast as the straight wall charger but it will charge up over night now. The auto switch to the clock does not work now as a side effect. This was mentioned above so I was not surprised about this.

My USB appears to be fine but I think I have seen another post mentioning a loose USB?
[Samsung Galaxy Nexus] blulite:
Some debugging info for those of you looking to make this work.

First put Gnex into ADB wifi, get to a shell on the phone and type:

setprop service.adb.tcp.port 5566
stop adbd
start adbd

Then go back to a computer and wifi ADB into the phone:

adb connect wifi.ip.address:5566 (example: adb connect 192.168.1.105:5566)
adb shell

That will get you a wireless shell into the Gnex. The on the new shell type:

cat /proc/kmsg | grep "fsa9480"

Now whenever you plug/unplug a cable you will see a message that tells you what kind of cable the phone thinks it is attached to. Thus far I've found the following:

'usb-peripheral' - connected to a USB port on my PC, or a non-Gnex charger

'charger' - the stock Gnex charger, I'm assuming this is a "fast AC charge"

'av-365k' - the Fascinate cradle, no charger attached, makes it go to landscape

'av-365k-charger' - the Fascinate cradle, pins D- and D+ connected

I hope this helps those that are having trouble making the cradle work.
[Samsung Galaxy Nexus] Wicked4u2c:
Thanks to this thread i have taken the plunge, specially since my old phone was a fascinate. I started dismantling it, so far when plugged the phone charges normally and also goes into desktop mode. I'm running 4.0.4 not sure if it makes a difference since some of you seemed to have problems. I do plan to take it an extra step and have it flush mounted so i get an oem fit. I want to have the old hole filled so I'll take it to my buddys body shop to have it painted and fix the edges that i screwed up from prying.
