My HD2 hardware mod- Wireless charing - HD2 General

I used a pixi charging back case (5.99usd) and touchstone charging base (9.99usd) to create this mod. You can find them on clearance at radioshack!
Can be made for other devices: ipods, iphones, bluetooth headset, etc...
Comment plz.
-Carnivore

Maybe some photos and more descriptions?
Im curious how this looks/working.

sure interesting, and most valuable as a proof-of-concept realization, even if I'de never go out with a setup like that

Hey, why do you use this microUSB port?
There's one marvelous thing about our HD2 : the dual-backplate setup
-> Use the golden plated contacts right next to the sim card.
They're used for the "old/weird" special car back-plate in order to make contact via the magnetic holder (aka the "original" car kit)
This way u'll be able to mod a plastic back plate with all the mechanism integrated, you just have to "make" two pins (and understand how the third middle one works) that connects to the HD2 motherboard
Hope that helps But i'm sure our HD2 will be the only one who will survive the wireless charging mod without too much trouble vs unibody etc

Nice
Yeah it looks nice but i don't think anybody is siriously going to use this do you??
Wy doing all this effort for making while you just can plug your charging cable in??
Anyways nice work. Good that people are trying to improve the phones usability.

oh I bet he's had a lot of fun doing it That alone is more than enough of a reason

I tried doing something like this a little while back, the connectors next to the sim card can be used for charging which would make the whole thing much nicer and easier, it worked good, but the HD2 metal door blocked the signal so it would not charge, so I used it with a sillicon case on top, it was good but not the best, then I tried to hard wire it inside, opened the HD2, it got few dust specs behind the LCD from opening, I tried blowing them away and the whole screen died, well it was a sad story which eventually ended up on ebay, and I had to get a different one I WILL NOT TRY THIS AGAIN, i hope.

thats good of you to try. hope you find a compatible plastic back for it or some other solution.
ill be looking forward to your progress on this as i have a palm pre and an extra touchstone charger.

The car kit's replacement back is also metal. But I will look into those 3 pins in back. Anyone know what they do exactly?

they activate the navi-panel and charge your phone at the same time. Do they have the navi-panel for the TMOUS version? I'm not really sure, but yea, if you're able to use the 3 pins inside, then it'll free up your micro usb connector.

I actually was fooling around with a microusb charging head and found that if you ground one of the data wires, the navpanel will show up. I was a little confused at first since I've never used it before then figured out it was a hidden feature.

does this cradle exist?

I am looking for a desktop cradle that will hold the Tilt upright that charges and has 3.5mm out on it.
google and you'll find
Hi :
how about this cradle
http://www.boxwave.com/products/desktopcradle/htc-kaiser-desktop-cradle_2642.htm
2 out of 3 is good, but no dice. There is no 3.5mm out.
just buy a 3 in 1 to plug into the back of that charger and job done
Well, you could always use a standard Arkon windshield mount except mount it on your desktop. Then run the multiplug out of the bottom.
I would also think about two other options....
One, contact boxwave... they are pretty good about stuff like this...
Two, spend your money instead on a pair of Motorola S9 bluetooth headphones and listen to your Tilt via bluetooth... with the added benny of being able to answer your phone when it rings.
If you can get the site to work, Seidio online has one that I think will fit your need. Sync/charging plug and a 3.5 mm audio plug. I think it's US$29.95.

I tried the one from Seido and returned it. It is a generic base that is supposed to work for multiple phones and my Tilt did not sit in it well. The bottom left side of my phone did not touch the base when the phone was vertical in the charger so unless I put something under it to fill the gap the phone would Tilt to the left probably bending the USB connection.
That's good to know, I was contemplating one. I think now I will take my 3-in-one USB connector and some modeling compound and create my own.
Fund with arts and crafts. I'll let you know how it goes.
I am using the same 3 in 1 like this one >>>http://www.boxwave.com/products/desktopcradle/htc-kaiser-desktop-cradle_2642.htm
I found it on ebay with a battery for less $$ about 6 months ago.
I saw that too, the difficulty I run into is that I use a form fitting case with a belt clip stud on the back. That means that all of the "device only" cradles, like what was in the prior message, won't work. I was thinking about the Seidio because it allowed for a skin case. Now that I hear it isnt very useful, I must consider other alternatives. Has anyone had success with the Seidio cradle?
Like I mentioned, my other alternative is to make my own by form fitting some sort of modeling compound around my Kaiser with case, then embedding the 3-in-1 cable in the compound at the right angle to fit the connector, then forming it to the correct angle. Sounds like a weekend project, now I just need to find the right material to do so. Hmmmmm.

What are the 3 Pins at the back used for?

Hi,
I would love to make a photo, but just have the HD2 here as camera and cannot take a shot of its own back
Anyone has an idea what can be connected to the 3pin hole in the back? If you open the back cover you see this between the microsd card slot and the sim slot, a little bit left unter the battery.
Thanx!
Those contacts fit the HTC car kit.
Ah the expensive thingy - thanks for clearifying
A pinout would be interesting. Stripped down mini usb, 1-wire with +-3VDC supply?
I am interrested in too.
even more interesting is htc have abandoned their interesting car kit design for a boring standard one that just plugs in the usb. saw it on wmpoweruser. still however has a high price tag!!
Tath s why I need the pinout, I aim to make my own with modifying a back cover.

HTC Hero USB / EXT port wear

Hi Folks...
I've been using a Hero full time for just over a year, and lately have had problems charging it. Seems like the USB / EXT port has weared down to the point where the cable doesn't contact as well as it should.
Anyone else had a similar problem? Wonder if this is fixable, or time for a new phone?
If you're talking about the cable just fitting loosely, you can always put a little bit of pressure inside edge the metal end on the cable to slightly bend it outward and it will help it fit a bit more snug.
If you're talking about it actually making contact loosely on the inside, you can always get a small piece of scotch tape and put it on the outside of the large side of the metal that fits into the phone, it will help push the contacts closer to the inside of the hero's usb.
Thanks for the suggestion, ill give that a go....

Same issue here, will be trying suggested solutions.
But I see no answer to your first question: Anyone else had a similar problem?

I had this issue with 3 of my usb cables that have pulled out while using the phone in disk mode and in the car charging. I used the method to slightly bend the connector outward on the cable itself and worked fine for me. One cable is a 12" that I use on my netbook, the other 2 are 3' -- one of which I use in my wife's car for charging and the other I use on my home desktop PC.
But there are other cables that I have not had issue with --the OEM cable I use in my car and I use a different cable at work. That said, in my case, it seems the issue is more with the cables then the actual port on the phone. Either way, by using one of techniques I suggested previously and what I've mentioned above, I have no issues now. I hope that clarifies the answer.
U seem to be right..... Different cables, diffferent results.....
Bought new ones and they work beautifully
I find this incredible, my hero's usb port is still really tight after over a year of use--to the point of being hard to plug in--especially the wall charger cable (uses the full ExtUSB?) which I use every single day. What do you guys do to the poor things?
My 3.5mm port has gotten a little loose though (shear force on the connector no doubt) but bending back the copper "spring" a little has fixed that for now.

[Q] Not charging unless I put upward pressure on USB cable

Hello everyone,
Since a few days my phone doesn't charge unless I hold the cable up and in the left or right corner of the port.
If I just stick it in, it doesn't connect/charge at all. And sometimes it says it's charging, but it isn't at all (or it's losing more power than it's receiving because it doesn't have good contact with the port).
Is there any fix to this or does anyone else have this problem?
It is NOT a problem with my micro-USB cable, I tried many, they all act the same.
Bad news
You have to replace your USB port, there's no doubt about, unfortunately!:crying:
Edit: there's a little chance to solve this by cleaning up your USB port...
i had this and it turned out to be dirt ground into the bottom of the USB port. A thin piece of wire from a tie wrap sorted it.
(of course, usually it IS a faulty USB port)

I suppose this is a stand for what I said:highfive:?!
hehe,. yea, , only to begin with i was countering your 'theres no doubt' remark, , but then realised i hadn't read your whole post.
Well guys, I tried cleaning. A layer of dust came of so I got excited, but it didn't work.
There also is way too much play with the cable when it's in, so yeah.
How much is that port change going to cost me?
from what I've read its not so much the price as the difficulty, , there are loads of stories of repair shops screwing it up. If you're a dab hand with a soldering iron, give it a go, or if you go to a repair shop, get down in writing what they are gonna do if they screw it up.
Yet again a good advice!
I wouldn't suggest to do it your self unless you're a soldering master: as samuel suggested there are (so called) profesionals failing to do this, just because it's tricky enough to get the job done the right way.:fingers-crossed:
Sometimes it is possible to resolve by tightening up the connector in a fashion that promotes the contact of the female to male contacts.
Done one dismantled once as easy to work on connector, basically I pushed the shorter edge in just slightly & with CARE on the female socket in the area over the contact plate thus forcing the male plug to push tighter against the contacts, also tweaked the to plug retention lugs so plug clips tightly.
Worth trying as if lucky can be a cheap easy solution & has worked fine on one I did but as only done the 1 I have no idea if it going to work for majority of worn plugs :-S
Replacing board socket is tricky & not that cheap normally as a good tech knows it a not liked or easy repair ... good luck
Thanks for the great advice everyone, I really appreciate it.

May take couple of adjustment to get it good & best do a little at a time.
Will only work if is contact issue between plugs, if issue is broken contact leg or poor connector leg solder joint to mainboard then no benefit.
Post back if get it working ...

Sure thing! I have one question, though. How do I correctly open up the device without damaging it (too much)?
Torx screwdriver and a thin credit card, there break down videos on youtube.
As above really, do your homework on stripdown & take a lot of care, back cover is easy if done right, plectrum is useful plastic tool for prying things apart or get hold of decent plastic opening tools, credit card can be used but too thick really.

Need to know what coaxial connectors are used for the 3 internal .cables

Does anyone know the exact type and frequency of the coaxial pin connectors for the cables on the board? I was prying the cables up with plastic spudger and one popped off board and I couldn't find it. I asked Digikeys support after I narrowed it down and they told me what I already knew. He said email samsung, so I did. It has been a couple weeks since and I got no reply so far. All I know is that they are active, surface mount, male pin coaxial connectors, I think. https://www.digikey.com/short/pcdqqt
I have no idea how to find out exactly which ones I can use. Please if anyone knows, help lol.

same thing happened to me on my note 5, I aligned both cable and connectors together and pushed it in, it was some what stuck together, then I used tape to secure them there for good. I have been using same phone six months no issues. I didn't open to check, since I didn't have too.. otherwise you have to find a repair shop to put one in, if above method wont work for you.

Tape doesn't sound like a very safe idea lol. I would think it would make the inside collect more heat. That or the tape could potentially melt. The s7 edges tend to get hot especially when charging . But soon enough I may just get a soldering gun and try to just solder it on but it still doesn't sound like a good idea. I might try that and then just buy a new board if all else fails.
