tilt not charging with sync cable but with power

Has anyone else experienced this? My tilt will not charge if I use a cable that is a retractable charge/sync cable. The cables work because I use them with other devices and they charge fine. If I plug in my power cable, the tilt charges. If I use a portable battery charger, it charges. If I plug the tilt into the sync cable that came with it (not retractable and plugged into a usb port), it both charges and syncs. But it will not charge/sync if I use the sync/charge retractable cables. Like I said before, they both work because I use them for other devices.
I know this worked prior to cooking my own ROM. But now it does not. I'm not for sure if the two are related.
Any ideas?
Thanks,
Alan

Firstly, make sure that under Settings\System\Power\Advanced that the box labeled "When device is on, do not charge the battery when connected to PC" is NOT checked.
If That box is NOT checked, it should work.
Secondly, & most unfortunately, check to see if the USB port on your device is bent, curved slightly, or is slightly lower on the right side.
If it is, then you've got problems & may need to RMA your device

Mine use to do that. It would charge on the AC charger, but would not charge
on a car charger. I eventually had AT&T replace it under warranty.
Take a look at the two pictures below. The top one is what mine looked like
and the bottom one is the new one.

A RMA may not be required, but the truth is, it is even quite possible that the cable is not capable of providing enought power for the kaiser to charge from. From my own experiance of retractable cables I have seen that they were not able to power my USB DVD-RW. While another, single, normal cable was more than capable. Id just like to add that the DVD-RW was meant to be only powered by USB. So try a different normal cable first before RMA. This as well the above posters information should fix your problems. If this helps, your welcome in advanced.

Great Pic Post! I can't tell you how many people have argued with me stating "If the USB is damaged it won't charge at all, anywhere, no matter what".
I certainly know that if it's a curved USB or slightly lowered on the right side it can definitely cause a loss of only car & PC-USB charge because it happened to me. People still argue though saying that's immpossible.

As another poster suggested, try another cable or try your cable on another device.
Im personally using an insten retractable mini USB cable, and I have no problems syncing/charging with it.

Erg. I looked at the usb port and I indeed had a pin bent all the way down. I tried to straighten but of course it broke. I purchased through Amazon (with a two year contract) so I don't think it came with a warranty. So that sucks.
Can anyone recommend someone to repair (close to Houston, TX would be nice ? Or would it be easy to repair it myself by replacing the port?
Thanks!

I have an unusual problem which is even worse!! My kaiser ONLY charges from the USB port on my computer. I've tried 2 or 3 car chargers now and the orange light comes on for a bit then goes off. Mains charger won't work either - orange light stays on but the battery level continues to decrease. It's a real bummer if I go away anywhere as my phone just eventually runs out of charge!!

Yeah, same thing going on here... my wall charger works when plugged into the phone, but I have a desktop stand charger that stopped working a few days ago... and I have the same thing going on with my phone's port...

I have trouble getting Activesync to pick it up. Usually says "must install 4.5" on my phone. I can usually delete the partnership and reboot and it works, but my pin is slightly bent.
Sucks.

where can i find the pin to fix this myself. Just the part. I looked at mines today and its slightly bent maybe thats why its it doesn't charge. I will look online in google.com but let me know if anything.

You can get it from pocketpctechs.com. I asked them the same question and here is the answer I got:
"Yes, we can sell you the usb port as a part only for $25.00 + shipping. Place the order online for the full service repair, then email me your order number and I can change the order before it's processed."
But of course it requires the skill and tools of soldering.

For whatever reason, my pin became bent in my mini usb port on my phone. It bends down to the right and my phone will no longer charge from my car charger, but does charge from the ac adapter and does charge and sync via usb (thank goodness).
I called ATT for a replacement phone and they told me that this is not covered under warranty. Oh man was I steamed. I told the rep that this was not my fault but was due to faulty manufacturing. I explained that the pin must sustain hundreds if not thousands of events of being plugged and unplugged as the phone must be charged daily due to low battery life. I've only had the phone for 6 weeks. How could this be my fault? So, after much arguing, he agreed to set up the exchange, but warned me that HTC upon receiving the phone may have my account charged $450 stating that this was user induced and not covered under warranty.
Can you all believe this?

Same problem here

Same here, maybe worse
Since I had a Hermes I had problem with this connector. It is not very durable, especially if you use plugged head-sets with the phone in your pocket.
It happened that my kaiser stopped charging properly in the mais, I had to leave it with something forcing from below for it to work : )
Then one day the worst happened, the plastic bit around the pins came off, and it bent, and trying to fix it broke.
end of the story, since 13th of december I gave it back to tmobile and I'm waiting for it to be fixed. They also told me that tmobile could not consider that as been defect. That connector is the ****tiest thing ever!!! How can that be my fault???? Anyway, I have insurance that I can rely on as a last resort...
Going again to the shop to check if there is any news about my telephone.
Meanwhile they try to push a G1 to me, no way...
regards to all

To make the long story short, I took it to the shop, they send to repair, then it came back with a dodgy power button, as they had changed the WHOLE board!!! Send it back to repair, came still a bit weird button, the manager then gave me a new Kaiser, nice end

Mini-USB car charger / IC intelligent chip

I have the HTC orginal car charger with Mini-USB connector. This car charger has and intelligent chip "IC" to prevent overheating when charge is 100%
Now, HD2 has a MICRO connector. My question is, if I use it with a mini-to-micro converter, will this "IC" feature continue working?

Talking about this:

And this:

wat, IC stands for integrated circuit.
Also, the charging mechanism to prevent overcharging or damage to batteries is on the device (phone) not the adapter.

Yes, the phone sends the "charged" signal, adapter receives it and stops charging and turns light indicator off.
What I am saying is that maybe the mini to micro converter will prevent that signal to be sent and hence continue charging/overheating?

Hello,i've the same thing and it works fine . All pins are connected in the adaptator .

no it's the phone that's drawing the current, not the adapter. Adapter is a "dumb" servant that serves current upon request.
the converter is just a wiring converter so again ther'es no intelligence involved.

Thank you!

I have 2 of that EXACT converters shown in the photo above... IT DOES NOT WORK!!!
For some reason, my phone will not charge when I use that adaptor... I also bought a Motorola one which works well

Thanks for the info!. Will get the Motorola converter as well...

Yup That one works fine and data works also... you can charge and sync with it

I have this
and cant sync with it, only charge, and i dont know why, because all pin are connect in two sides.

Guys,
I use Motorola P513 microUSB car charger. It works like a charm. After fully charged HD2 disconnects from it so there's no possibility to overheating. I really recommend it. An it looks fancy too

Dude... 1 have two of those and they both wont charge... not in car, via charger or anywhere else.... I was so pissed off as I got two of them... thank goodness for the Motorola one I ordered as a backup. That one even allows sync
THe one showing in the picture... when I plug it on the cable with the other end in the cigarette lighter adaptor, the cigaretter indicator light goes out on that end as if a circuit has been cut.... this happens even without anything plugged in and happens with both adaptors I bought... nothing charges also.... pissed me off!

from what i see that is also a surge protector. 8v to 3v, being a surge protector, it has a capacitor inside, and that will naturally block all data connection.

Could you provide a link to that motorola adaptor ?
I have searched Ebay and all the adaptors I found, specify they can only charge the phone, but not transfer data.
For some of them I also asked the sellers, and they said just the same - Charge ONLY.
Thanks

This is the one... as long as it looks like this... I am using it right now as I type this

Thanks for the reply.
I tried checking where and how they ship - and (as in many other cases) it seems they only shim within the US.
Since Im not in the US . . .
Is there any other one ?
About the comment that says - "as long as it looks like this" - well - I saw several of them, and as I mentioned in my previous post - they specify that they (the ones I saw) only charges the device, and when I asked the seller - they aslo claimed that it's only for charging, and does not transfer data.
(maybe they look the same on the outside, but the wiring is different ? - I wonder)

Be careful.
By the time you plug a mini USB plug into such an micro adapter, the potential leverage on the phone / micro socket will be quite considerable!

Why? What do you mean exactly?

The above one piece adaptor together with the charger's Mini USB plug is similarly rigid & I'm guessing about 2½ to 3 inches long - maybe 10 to 12 times the length of the actual micro socket! Some 10:1 leverage ratio. Maybe 3 times as much as without an adaptor.
I doubt that the design spec of a USB micro socket was ever designed to withstand the potential force that even mild accidental input leverage applied at a right angle would exert, on conversion to output leverage, on the phone's socket. For example, the leads tend to be 1 metre and are quite restricting. with the lead at right angles to the phone, 'testing' the cables length, the 'moment of force' (technical term) applied is likely to exceed the the design spec of the socket many fold.
I am suggesting there is a risk of separating the socket from the phone's chassis and/or its electrical connections to the printed circuit board within the phone.
At the vary least, due to the cables inherent stiffness, over a period of time the phones micro socket will get enlarged / bell shaped simply from small gentle leverage movements. IE. whilst USB connected, simply picking up the phone, messaging, or making a call. Eventually electrical / mechanical connections will gradually fail.
To reduce, but not eliminate this effect, I would suggest an adaptor cable as opposed to a one piece adaptor.
(Think I've waffled a bit here, but hope I've conveyed what I mean)

Recipe:
1 dock connector from Kineteka
2 10k ohm resistors - needs to be 20k, a single 22k is too much
1 donor USB extender cable
Various heat shrink, tape, etc to taste
Pinout here. With the connector plugged into the Tab, and the Tab oriented with the chat camera on top and the connector on bottom, pin 1 is to the left of the connector.
Chop off the plug end of the extender, separate out the wires, cut / strip / tin. Cut off the shield. Slide on the plastic shroud for the dock plug and a piece of heat shrink for strain relief. Don't forget this or you'll have to undo the whole thing (like I did). You might also want to cut thin heat shrink to go around each wire to protect it from shorting at the connector pins.
Solder the two resistors in series and put them between pins 13 and 15. This tells the Tab to go into OTG host mode. Be creative. Surface mount parts might be better here.
Solder:
ground (black) to pin 1
green (D+) to pin 3
white (D-) to pin 4
red (+5V) to pin 6
Test this out before shrinking the pins by plugging into the Tab along with a USB key. If it works, you should get the message above.
Once it works, put the connector shield, spring clip, and shroud on.
All said and done, this comes out to about half the price of the Samsung adapter, but at the expense of some elbow grease and potential unreliability. I expect clones will be showing up on eBay someday though, so if I've done anything useful here it's to entice our friends in China to start their assembly lines.

Clean it up and start selling them imo.

Better?
Taken before I have to ugly it up with a bit of hot glue. The connector housing is too shallow to fit the resistors and make a good strain relief with heat shrink. I also noticed that the retainer ring that holds the housing together pops right off when you unplug the connector. A little super glue needs to go there too.

Nice job dude specially since they are taking forever to release the damn thing

Lol. This is awesome goodjob. Might have to try this out

Well played
I'll give this a shot

i'm hoping that the connector can allow you to utilise many of the pins at once.. i'm thinking of designing an all in one connector that has USB host/OTG connectivity and allows me to charge the device and still allows me to use HDMI/component video out

I will pay you infinity for that, give you my firstborn, whatever you want. But seriously, what use is a "media dock" if you can't charge while I are passing hdmi thru.
Back on topic, nice job OP, that is my new weekend project

Nice job.
Since I don't have a galaxy tab 10.1 . I have an idea :
Is it possible to use female female usb adapter for the GT ?
does any GT10.1 owner verify whether or not this method is working?

Nope, won't work. With this you won't get the 5V power from the tablet, and you won't have the resistor on the ID pin to tell it to go into OTG mode. I suppose you could provide your own 5V power to the device, and hack the kernel to force it into OTG. But that's probably as much trouble as building a cable anyway.

This is awesome! Do you know if it will handle only one item at a time or could you hook a hub to it and run like a hard drive and keyboard at the same time?

Haven't tried a hub yet, but I'll do so when I get home later. The Transformer has multiple ports on its dock so presumably that should be ok. There is a power budget limit though, since I got a dock warning about overcurrent when I tried a USB powered hard drive. A powered hub might fix that.

If you create a cable that charges the Tab while using it in host mode, you could probably pull the power off the charging cable instead of from the accessory pin.
If doing that, might want a selector switch or diode to keep current from flowing into the accessory pin.
I ordered a few of the 30pin connectors yesterday and I am starting my designing now for my "docking station". I am trying to figure out if I will have 1 or 4 USBs on it.

Why you didn't you use one 20K 2% ohm resistor instead of two 10K ohm?

I didn't have a 20k resistor on hand, and 20k isn't a common value in smaller resistor kits. The most readily available values in the 10k range are usually 10k, 22k, and 47k.

Sure enough, with a powered hub I can hook up a USB stick, a USB powered hard drive, and a mouse. I tried a USB audio adapter as well as a 360 wireless controller via the PC USB wireless adapter, both were unrecognized. I think I remember hearing that the latter was explicitly unsupported, though I figured I'd try.
Disks show up in /sdcard/usbstorage/sda /sdb ... for as many drives as you plug in.

So does HDMI share any of the same pins as the USB? I ask because I am gonna piece together a hub and then add an HDMI cable to that, and then plug that into the media dock, and then it will be a true dock. Just need to get power for charging involved in that mix

can you try hooking up an usb microphone? I'd like to see if they will work and how well. I have a samson go mic that I wouldnt mind using as a recording tool.

Doesnt the orginal galaxy tab's hdmi dock work on the 10.1 i saw vidos of it working on the google io version should be easy to add a switch and usb to it

My Super Cheap super cool in car Nook Color Mount

How's it going everyone, I just thought I'd share the mount that I've created for my Nook Color. Excuse the pics, I took them with my phone.
Before I get into it I there is a list of requirements that I had for my mount
1. It had to be as cheap as possible
2. It had to be one that I could easily remove my NC from to avoid weather damage, theft, etc
3. I couldn't make any modifications to the vehicle because I may eventually want to sell my car.
The things that I used for the mount are
1. some double sided tape ( $4.00)
2. cable hooks ( $2.50 )
With that being said here are some pictures of them
This is the set up for my mount. It's pretty cheap but it is SUPER effective.

}
If you notice, I've circled the top and the bottom to let you know how they work.
At the top you will notice two pieces on the left and the right, those are pieces of double sided tape, the reason that I put those there is because before in my first attempt, the NC would slide out and fall any time I turned my car, these add a decent amount of friction to reduce the sliding to when I make a sharp turn which is almost never.
The Velcro in the middle is from my first experiment, it doesn't do much anymore.
The bottom is 6 pieces of double sided tape, one side on the molding of the car and the other side is on the cable hooks that I used (pictured below)
Because of the shape of the molding I had to bend the hooks to make them conform. They are perfect because they are cheap enough and easy enough to bend that it wraps the NC with just enough grip so that it won't move.
Using this set up I have a mount that cost me less than 10 dollars and I love my carputer. Below are some pictures of the mount in action
Here's one during the day, you can't really see much
Here's one that I took of it at night, it's a little easier
For version 2 there are a few things that I'd like to add to take advantage of USB host mode but I have a few questions about it.
1. Does anyone know of a usb hub that I can use to be powered by and charge my NC at the same time? for example, I have a usb charger that I could use but when I use my hub I can't charge and use host mode at the same time, and I've enabled it in Nook Tweaks.
2. Does anyone know of a good enclosure that I can that has low enough requirements that the nook color can power it, or a 2.5 inch enclosure that can be powered by my cigarette lighter and then used with my NC?

Hey this is really cool. About what you were asking about how to power it, if you were going to use a hub you would probably need a high amp powered hub to be able to fast charge the Nook, otherwise it will only get a trickle charge. You would then need a cig adapter for the hub. I think a high power cig lighter usb adapter with two ports is more of what you are looking for. Keep up the good work and post your progress please.

very very nice idea..good for you

If you are fine with the regular trickle charge, you could just use a Y-Cable to add 5Volt from a external power source... that in combination with a normal USB to Micro-USB Cord + USB Genderswapper could give you the result you want...
However that way you will be limited to just one USB device, but seeing as you seem to aim for a external HDD this should be enough, right?

thanks for the suggestions, I'm looking for a good high powered usb charger for the cigarette lighter but I don't know of any that can fast charge a NC, do any of you guys have any ideas?
also the situation that I am facing with the external hd is that I can't find one that the nook can power on its own, If I could find an external powered hub to get it spinning I could use host mode that way, I just have no idea which one will do that
Edit: Can you guys see the pictures?

Nexus 10 Car Install

Alright so I made that dock for when the Nexus 10 is at home, but what if I want it in the car? Next project! I basically used the Exogear Tablet Mount along with Pogo Cable and Griffin Bluetooth Adapter to fully intergrate the Nexus 10 into my car. Thought I'd write up the details just like the dock in case anyone wanted to give it a go.

There's actually a lot that went into this, because:
1) It charges the tablet
2) Integrates with my car speakers
3) Is tethered to my phone, also mounted in the car
Stuff Used:
1) Tablet Mount
2) Pogo Cable
3) Phone Mount
4) Tablet Bluetooth
5) Phone Bluetooth
6) Power Adapter
7) Add a Circuit
8) Cigarette Lighter Adapter
9) AUX mixer
10) AUX Cable
11) PIE Interface
12) RCA Cable
13) Passive Amp
14) Ground Loop isolator
Step by Step
Step one was finding a mount/holder for the tablet. This one from exogear worked perfectly. I wanted charging, so I knew I wanted to integrate the pogo cable in somehow. I thought I would have to mod the holder a little but it was perfect as is - the pogo fits snuggly in the bottom:
Just force the usb end of the pogo into the hole at the bottom of the holder and you're good to go. I won't go into the details of removing the dash because every car is different, so I'l just say, get that cable inside the dash and leave it for now, we'll get back to it later. Lets stay on the outside for now. Next step, mount the phone:
Pretty simple. I found this mount to be the best - it was simple and allowed me to mount and dismount the phone quickly. I zip tied a charging cable for my phone and snaked that into the dash.
I integrated to my car stereo through bluetooth. But I wanted both the phone and the tablet to be connected. So I got two bluetooth devices. The trip here was to find ones that would auto connect without pressing any buttons on them since at least one would be behind the dash. And this was surprisingly hard to find. But this one from Griffin was exactly what I needed. It just plugs into a cigarette lighter and has a cable for Aux fro sound.
For the phone, I wanted one that I could use for calls and could control the phone with. So I mounted this little guy from Kinivo to the steering wheel. The one wire coming out of it split at the end to an aux for audio and a cigarette lighter plug. Bring that cable inside the dash.
Ok, so inside the dash is where all the magic happens.
So now we have to power everything. We have the following: USB from the pogo of the tablet, USB for the phone, 2 cigarette lighter plugs. Let's plug it all into this guy
But first you're going to have to modify it a little bit. So even though it says it can output 2.1A and 1A, that's only for apple products. Android handles things a little differently. If android detects that you're plugged into a usb port rather than a wall charger, it will only pull 500 mA regardless of what current is available. So we need to tell android that this is a higher current source. We do this by soldering the the two data lines in the usb together. The data lines are the middle two of the four. Just open up the case for the adapter and drop a ball of solder on the board for the middle two pins of both USB connectors. Trust me it works!
Now we need to plug the adapter into a power source. The easiest way to do this is to plug it into and cigarette lighter. But you don't find those inside the dash and I didn't want any cable on the outside, at least as little as possible. I wanted all the guts to be hidden. So for me, I had the fuse box under the driver's side dash which I wanted to tap into, and I think most cars have a fuse box in the same area. Find a fuse that is only powered when the engine is off. This is important, we don't want to drain the battery when the car is off. Once you find the fuse, get yourself an Add a Circuit . Very handly little guy. I used a 7.5 Amp fuse which was more than enough current to power everything.
Once you got that in, you'll need a cigarette lighter adapter. Connect that into your add a circuit and plug your power adapter into it and, boom, everything is powered.
Now we have to deal with the audio. I wanted both devices to have access to the speakers at the same time. So I needed a mixer. The strange thing is there is no such thing available for sale that I could find. I only saw stuff for high end musical equipment and so on. So I had to build my own. There's good guide how to do that here so i won't detail the instructions here. Those instructions are to build a 4 to 1 mixer, but we only need a 2 to 1, so it's a bit more simple but the basics are the same.
OK once you have that, plug your two AUX cable into the input and get yourself an Aux cable for the output.
So is where each car is different, but you need to get a PIE interface. Just find one for whatever car you have and use it with RCA Cable to hook into your car stereo.
Bonuses
1) If you find that you're volume is pretty low (which is likely due to the mixer), you'll need to get yourself an amp and put it in line. I got a passive one from here :http://phpaudio.jigsy.com/passive-preamp and I can vouch that it works great.
2) Be aware of the ground loop. If you're hearing excess noise, you might be coupled into you car's ground loop. The telltale of this is if the pitch of the static noise changes as you accelerate. If you get that, there's an easy fix. Get yourself a ground loop isolator to put in line.
Software
To wrap up, there are a few pieces of software that make the thing even better. One is of course Tasker. Set it up so that your phone automatically turn on wifi tether when it connects to both the bluetooth of the car and to the tablet. Second is Tablet Talk. It allows you to dial, answer and make calls from the tablet. It's an awesome piece of software and has great Tasker integration.
That's all I got!

I have only one thing to say....Wow!

Dude, nice! Great thorough guide...I will seriously consider doing this!

This is awesome. Well done
I'm STILL waiting for the official dock, or a dock that charges and has aux sound through Pogo, to start my car build. So I can charge and have aux sound run through the dock.
