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.

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.
Hi,
In our current research, we want to measure power consumption of an I9250 doing various network related tasks. To do this, one of our electronic wizards must connect his instrumentation tools to the battery pinouts. He told me he needed to know the resistance of the two extra pins (those two except + and -)
Anyone who knows this, or has done something similar?
Best wishes,
Morty
So as I understand it those are not used to provide power for the battery. These other pins are used to communicate with the battery (and if it has NFC) use the antenna embedded into the battery. Your engineer doesn't need to do anything with these but connect them straight to the phone.
Out of curiosity is your research going to get published anywhere? I am really interested in those types of numbers
Hi thanks!
We did similar test on the Nokia N900. For this phone, we had to add resistance to the third pin (the additional to + and -). The results are not published, it was part of a master thesis for one of our students.
The experimentation with the nexus is also part of a master thesis, as always we hope it will end with a publication! We can then provide some results.
Well I don't understand why they need to do anything, if they pass these straight through and tap the power lines the battery should work fine (appear transparent).
If that doesn't work then you have two options. The first thing is to buy a replacement battery and take it apart. The second would be to go into your lab and use a scope/meter to measure those lines and see what they do.
Hello,
I have an idea:
Posting what are some usefull tools for hardware hacking. Both hand tools and software...
I think it would be a good reference...
What do you think?
1) a screw driver set, probably like those used for mobile phone repair. I got one with 33 interchangeable bits.
2) a digital multimeter, the more checking options the better. Or simply a cro( oscilloscope)
3) a good antistatic soldering iron( prefer goot from japan). Hot air gun with temp and air control ( optional)
4) thin solderwire, good white flux, ipa or tinner, desoldering wick, desoldering pump, soldering - de soldering assist kit( optional)
5) magnifying glass or stand with illumination, a portable filament lamp( in case u have to dry out a circuit board with ipa or thinners) , pcb holding stand( i got one with a magnifying glass too). A small magnet or box to keep unscrewed screws, so that u may not get screwed up by lossing some of them.
6) bunch of wires, pins, jacks, and a plugsocket or extension box with fuse protection and univeral plugs( i made one myself)
7) last but not least.. virtualy every thing u need for a particular work, its bit electrical and electronics. So any thing u can manage will become a tool.
8) a bench powersupply with 0-30 v adjustable option( i modified a comp smps to get it, smps supply gives stedy and stable supply compared to transformer based ones. Though it gives max 12v o/p it is enough for most works, as i got another 0-30v transformer based supply, i never had to use it for any of my mobile based works). A ups if u want.( the comp ups with 700w is a good option)
Rules;-
1) always keep ur workplace neet
2) keep all tools handy, and easily accessible from where u sit.
3) use good lighting( i made a 3w led adjustable handle lamp with lense, so that it focus properly on my work area only, keep the light so that it dont falls directly on ur eyes)
4) do handling of static objects with bare foot on ground, just to avoid static charges from ur body. Or use antistatic matts and wrist bands
5) use of correct tools makes ur work clean and also saves lot of time.
6)never mess up ur work place with wires,chargers,datacables, tools, etc..
7)patience ... hope ...determination ... optimism ...( with out these u will never gona make it)
Thats all.. i got for now.( or what that came into my mind for now) . U all add some more spice if u have`em.
Hit the thanks button if i helped u...
Regards
Shah

Very good reply....
Anyone else want to add anything?
I think that covers it. Other things that I would add is an assortment of clips for probing / attaching. Maybe a scope but I don't think that is required for much. As for software, I don't know, I don't use a lot of software but I find adb and Kies being really useful.
Software's:-
1)XS ++ :- software for flashing/ moding sonyericsson Java phones
2) setool :- same as above, with more options
3)a2tool:- same as above but for newer se Java phones
4)universal box, jaf box, :- Nokia,LG,se,etc flashing.( Java phones)
5)ireb, f0recast,:- iPhone
6)adb,hd2 tool kit,alpharevex,goldcard tool,z4root,gingerbreak,android kitchen, android sdk, Odin multiflasher, :- tools for android devices
7)wp7 toolkit, wp7sdk, zune, wxap assistant, update cab sender, multi xap installer,hspl / spl installer :- windows phone tools.
Dudes these are few tools I had used, but not all, its hard to mention all, as thousands of them are out there..
The main info I can give is to Google searching your need with "tool" at its end. U will get it.
Eg:- xperia arc unlocking tool, sensation XE rooting tool, etc...
from hd2 running hyperdroid 5.7 on dorimanx 3.8
HW dev tools and asociated SW here :
just google for "microchip technology android" they have many others
Core phone analyse/modding stuff? JTAG + OpenOCD/CrossWorks. Allows to debug/resurrect/low level software and hardware analyse any ARM based phone if JTAG pads are exposed.

Does anyone have experience with gas soldering irons?
Thank you all very much. Very good info
agree
+1 for this thread. very useful
Shadow, u mean oxy-acetline torch used for welding or gas soldering iron like those of hako,?
I got one gas soldering cum heating soldering iron, portable, interchangeable bits, but its too hot for mobile reworking, u can burn ur board.

Did no one mention a signal generator for injecting signals?
Most modern multimeters / oscilloscopes have signal injection features, even cheep chinees multimeters have it. Its ok for normal use

The Rigol DS1052E mentioned above is excellent, although honestly I wouldn't buy it from DX. I live in the USA bought mine from Saelig - it has been replaced by the 100 MHz DS1102E for $400.
The Open Bench Logic Sniffer can be a powerful tool, I honestly have barely used mine so far though.
There's an open hardware JTAG dongle (Bus Blaster) that is very inexpensive, but I do not know if it supports target voltage levels low enough for interfacing with most phones.
Other cool stuff for general hardware/microcontroller learning/experimentation:
Gadget Factory Papilio - FPGA learning/development board
Adafruit Boarduino - Inexpensive breadboard-compatible Arduino hardware. I strongly recommend using AVR-GCC instead of the Arduino IDE though
Adafruit ATMega32U4 breakout board - Make a USB peripheral for only $20!
The cheep solution for replacing expensive digital oscilloscopes,tracers,injectors, and every thing that read signals and show it on a screen.
A laptop/netbook/computer and a data logger card.
A netbook+multichannel( max upto 8 analog+digital i/o channels is enough) will cost u 1000-1500$ and will be a good companion. As far,, all of us have pc or laps. So its what we have to spend few hundreds for data logging card. Thats it. Multipurpose multisolution device. Possibilities are vast.. compared to ossiloscopes etc.

hello
my hd2 'was' dropped, it is working, but backlit isnt.
Now... do You have an idea how can I use this phone, while backlit is not working?
Is that possible to stream audio from one to another android device? im thinking in connecting hd2 to my old panasonic midi hifi ect.
Do you have another ideas?
Beside that, would be Note 2 good replacement for hd2? i'm concerning baout the size.. i was using note1 for short time, in pocket i was ok, but i was not too handy to use only with one hand.
Buy a new lcd & digitizer combo for about 20USD & fix it.
Note 2 is big to use daily if not a lover of large devices. Assume you are an android user & if so plenty of device choice from likes of LG too with removable battery, sd slot & status LED which are basic features missed out on some of today's cheap designed so called advanced technology smartphones ...
Hey XDA!
[This is my first thread, so please excuse any abnormalities you may find here. Corrections/ help would be appreciated. Thanks!]
As tech has progressed in the last couple of years, I have come to replace my beloved nexus 10 with my ever-more-powerful LG G2.
This transition is soley because of spec enhancements in recent devices, but very recently I realised what a horrible waste of an amazing (and still somewhat powerful) device that is, and I'd decided to do something about it. So, I shelled out a few of my Great British pounds (less than £5) and bought myself a microHDMI cable, and a USB OTG cable. I found an old USB keyboard, USB mouse and powered USB hub (not sure if it's necessary to have a powered one, but its all I have to hand), and got going on my small project.
[TL;DR: Ive got an unused nexus 10 laying around and a few other PC peripherals, as well as a microHDMI cable and decided to start a little project]
I realized the nexus 10's potential because of all of the useful (and more importantly- seperate) ports it has:
- MicroHDMI out for a monitor/TV (not necessary)
- MicroUSB port w/ support for USB otg
- Pogo pin port for charging, so battery is not an issue.
All of these things together can be used for a portable android- powered PC! So I plugged in all of my cables, and thought I'd be ready to go, but of course, that would be too easy.
Things that worked:
- USB otg cable and respective devices (keyboard, mouse, 16gb USB stick)
- MicroHDMI video out (sorta)
- Pogo pin charger
Things that did NOT work:
-MicroHDMI video out (screen size/ratio/density)
-MicroHDMI audio out
-Easy usability (phablet-style stock ROM does not like mice.)
Fixes/ work arounds:
1. MicroHDMI audio out:
This was probably the easiest (and therefore first) fix. I remember reading on another forum about the same issue, and it is easily resolved by turning the nexus 10's volume all the way down before plugging the MicroHDMI cable in. Worked first time, like a charm. However, in some cases this does not work and may require flashing another ROM, I personally reccomend cm10.2's most recent stable rom, as it is exactly what I am using. (if you are looking for the same outcome as me, this rom maybe a requirement anyway)
2. Ease of use:
This part did require flashing a new ROM. I used CM10.2's stable build, and banks GApps. Other supported ROMs are listed in the thread linked in this "2. Ease of Use" section. I used the flashable zip file listed in this thread: ( http://forum.xda-developers.com/showthread.php?t=2451956 ), to change from the mouse-unfriendly phablet ui, to the mouse-friendly tablet UI. This made the nexus a lot more useable as an android desktop/portable PC.
3. MicroHDMI video out:
This is a little more awkward, but it is still relatively easy and do-able. I did a little searchng and found this post ( http://forum.xda-developers.com/showthread.php?t=2294786&page=3/#25 ) which links to an apk specifically made for fixing this purpose. I downloaded and installed the app (Named something like ScreenRes I think - the exact name escapes me) and checked the box which said "Resize the screen when HDMI state changes" and used these settings for a 39" 1080p screen:
- Screen height: 1080
- Screen width: 1920
- Screen density: 280
Unplugged and re-plugged the cable, and voila!
PLEASE NOTE: This apk does require root access, and I have ONLY tested it on the CM10.2 stable build. This is the ROM I reccomend for this project/purpose. Also, dont forget to thank sbradymobile for his easy-to-use app!
The end result? A very useful android PC attatched to a beautiful 39" display bringing new life into my once-dying nexus 10. It's a shame to replace the beautiful screen on this thing, however with a cheap tablet/phone stand you can take tablet away with you and a keyboard and mouse without loosing any settings, files or convenience for a more portable android PC. Granted, It's not the most beautiful looking thing, but with a little cable management tou can make a neat and tidy android PC set up.
This is particularly good for productivity (e.g with apps such as kingston office, or- creating threads like this on XDA ) as well as media consumption, for things such as movies and with apps such as cheapcast or droidmote you could make a nice mid-point between a chromecast and a fully fledged laptop/PC.
Sorry for such a long post, I just wanted to share this idea as even though I'm sure there are others similar to this, I think there are other people like me finding their tablet being used less and less.
Please feel free to leave your thoughts and questions below! Thanks!
Sorry for the long post
Just a minor suggestion. When an OTG cable and the pogo plug are both connected the pogo plug does not charge the N10. Do not believe the charging notification as it shows charging which is false. There is no ROM for the Nexus 10 which can correct this issue.
As you mentioned a powered USB hub in your configuration then purchase a OTG Y cable so that one end goes to an OTG device as usual a normal M/F USB cable goes from your Y OTG cable to a powered port on the USB hub. It will only trickle charge but that is better than using battery only.

Thanks! Ive realised this and will ammend the post soon. This is a little annoyance however as the nexus 10 has a rather good battery life I can use it till I'm done and then put it on charge with the OTG removed
