I tried to soft reset my tytn II in the dark, and accidently put the stylus into the usb/charging slot and somehow screwed up my phone. It will not charge, or connect with my computer. Any suggestions?
OMG! I did the same thing, but luckily i didn't do further damage except the copper parts become bent
HTC should have done something about this! i am sure many other users did the same
can u take it back to your supplier for warranty claim?
same problem here...
i could bend back the copper contacts with a WOODEN (!!) toothpick (dont steer around with metal in there....)
Looks like i tried to reset the device in darkness last night and fumbled around in the usb jack.
Damn... really bad position for the reset-button!
Same issue here-- though some chargers now work, some don't. My phone will charge with my OEM charger and usb to computer, but not my 3rd party wall charger or my car charger. Aaargh
Same Problem Here
Check out this thread at AT&T Forum regarding my attempt to get a replacement phone.
http://forums.wireless.att.com/cng/board/message?board.id=cingular&thread.id=65536
I got mine replaced at the store. I was under 30 days and was lucky.
I am going to order one of these:
http://www.eforcity.com/silicone-mini-5-pin-plug-for-motorola-v3-2-pc-smoke-cmotv3xxpc01.html
it should fit. i also heard that certain verizon phones have rubber usb plugs on them. I may just stop in a verizon store and see if one fits. My tmobile wing had one on it and it worked great to protect the usb port.
Well...I did the samething last night. Tried to soft reset my phone while driving in the dark. Luckily I've had my tilt less than 30 days, called and now all I have to do is go to the AT&T store for a replacement....Also, I'm going to pay 10% restocking fee so I can get an extra battery and charger...W00T!!!!! I actually saved about 50 bux
One way to avoid doing this in the dark is to flip the phone upside down, locate ExtUSB socket with your left index finger, keep your finger over the socket and slide your stylus down your finger tip. Of course the easiest way is to turn a light on.

true, but for those of us with this problem already, it is too late
Luckily, I tried a newer charger, and my car charger, and they both work. As far as connecting to my computer, I have to use my Y cable that was included with my old 8525. I'm still pissed, and I have a TyTn II and not a tilt, so warranty will be a pain in the ass, considering I have to send it to the UK. If it starts to act up, I will have to send it in, and if I get it fixed, I will definitely buy one of those plugs from the above post. Thanks for all the replies, and good luck to everyone with this problem.
Lesson # one don't put things in holes in the dark in bed
Well, good news is ATT is sending me out a replacement phone for free since I am still under warranty (outside the 30 days, but inside the 1-year). Now I just need to re-flash back to OEM status so I don't get busted on the return...time to test out the "Idiot's Guide to Re-Flashing Back to Original ROM" and see if it does me right.

that's why I have so many kids!?! anyways I had my phone charging in my car and it fell of my seat onto the floor. the nezt day I noticed it wasn't charging (tytn 2 no easy warranty fix) I then noticed that inside the usb thing is a black plastic piece with the small metal connections. the black piece was bent a little on one side so I removed the battery took a pair of tweazers and bent it it straight again than I took some forced air in a can (for a computer keyboard) and blew in there to make sure none of that cheap plastic shredded and got in the way of the metal connections. it looked like after I used the tweazers some of that black plastic chipped off (very small pieces) anyways after that it worked perfectly. hopefully this will help others
well it seems i messed up now and stuck my stencil in there one of the small Metal wires is out of whack now ad some chargers work and some dont did anyone get a plug yet?
pissed
so I live in metro detroit with a tytn 2 not a tilt. after I stuck my stencil in there it seems my car charger don't work. when charging with my audio adapter its flaky losing some power, maintaining, gaining some power. but when I use my wall charger with no adapter it charges!! if you put the kaiser flat on the table I see by 2nd wire (in the hole) is bent down(whereas the others are up) and its sitting in the middle of the whole.(my buddy told me to use a needle and a magnify glass because the 2nd wire was actually bent all the way down but I got it in the middle after messing with it. when that one wire was out of whack my car charger gave me a red constant light (no charge) after the stencil incident. I hope all that helps somebody! anyways so I call HTC first they tell me that's not covered under warranty. Then they tell me I have to send it to houston tx for 3 weeks. Then they tell me it will cost $300 usd to repair!!!! this is insane for a little miniusb piece that got hit once with a stencil. it probaly cost 22cents. what is everyone else doing? I think if I can get that metal piece to stick to the top it'll be fine. I just switched to att and I have 6 days until im locked to a 1yr contract I could buy a tilt for 250 or whatever but id have to sign a 2yr contract.
I stuck the stylus in the USB port as well but luckily I didnt seem to do any damage. I did bend it a bit but with some gentle pressure in the opposite direction it went back into place. I havent had any problems charging or syncing since then, so it seems I got lucky. Just gotta hope I dont do it again, lol.
ya the black piece as a whole seems to be able to bend a little but if u mess the little little metal connections in there you're gonna have problems
Hi, this is my first post and I hope to help someone. I had the same problem with my phone, it charged with the home charger and in the cradle but the car charger won't work. using a close light and a magnifier I could notice that with the phone with the screen upside looking at the usb connector that the pin al the way to the right was flat and a tip was showing as opposite to the others. I returned it to the former position and voila!! it works. I hope to help someone.
Ok, so i have the "power button failure" problem. No more warranty, and the local gsm repair shop can repair it, but doesnt know where the connections go, to make a bypass.
anyone has this manual, or anything that could help me?
thank you
You can't repair it.it needs a new flex cable.

I had this problem recently. Out of warranty. Sent to HTC repair center and got quoted for about $50 USD (given that I'm in Singapore, there is a physical HTC service center that I can go to).
If you want to fix it yourself, you can buy the board from ebay, this is the cheapest of them all, with tools included.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290522246328&ssPageName=STRK:MEWAX:IT
You can follow some disassembling guide from ifixit or this youtube series (very detailed, but to repair the cracked screen instead) to replace the flex cable and board. Should not take more than 1 hour. I planned to do it if the quote is higher than $80, but it's not.
Let me know how it goes if you decide to fix it yourself. Take a few pictures as you go along would be great too.
Easy way to start nexus one with out power button:
1)Plug in phone through USB or wall charger.
2) take battery out
3) put battery back in real fast
Phone should boot on.

thank you guys for replying, i knew i can replace the board, bu i wanted to see if i can "fix" the flex cable. i gues there are only 2 wires inside it and i need to see where those go. not to fix it myself, but the guys at the shop. i think they can use a "strap", which is a loose wire connecting the 2 points. i dont really plan on using that button very much, i got used to the trackball wake, but, i want it to work, just in case

I've taken my 2 nexus apart, and I can tell you that there is no easy fix.
ok, update
i have fixed it in the gsm repair shop. well, they did
they waited to come in another faulty nexus to check which wires were faulty, compared them, and they put in a new external wire replacing the old one on the circuit board. everything works now. it costed me around 30 usd. anyway, i intend on using trackball wake though in the future, only if necessary the power button
Hi ,
Yes you can repair this problem. Besides the option of buying a new flex cable for 50-80 USD, I found in this very same forum a thread where somebody posted a picture and indications about how to repair the flex that contains the power button.
If you disassemble your N1 and remove the large flex that carries the power switch you will notice that i has two large connectors on the bottom end.
One of these has 44 pins (two rows of 22 pins). In the top row of this connector, counting from the right the pin number 10 is the one that turns the nexus one ON/OFF
The switch does this only by connecting it mmomentarily to ground.
TO FIX IT:
All you need is a fine end soldering iron, a good lens, a T5 screw driver, soldering wire and adhesive tape. And most importantly 20 cm of very thin magnet wire (enamelled copper wire of about 30 to 50 micrometers in diameter (it is thicker than hair do not worry).
Then solder an end of the wire to the pin #10 as counted in the way i described. route and tape the wire along the flex until you get to the switch.
the switch has 4 pins one pair is ground, the others go to pin #10 in the 44 pin connector. The ones that are gong to the pin #10 are actually on the side of the switch that has a golden "[" bracket. Solder the end of the wire that comes from pin #10 to any of these two pins of the switch. This completes one part of the process. (the most difficult).
The back of the board that holds the switch has a large ground plane. Solder a second piece of wire to this golden pad. From there, stretch about 30 mm of wire towards the upper corner of the logic board, and solder the end of it to the round golden pad where a screw goes. This is a ground point.
Reassemble the phone. Your power switch should now work again.
I hope this helps.
Jose
This may seem obvious to the tech savvy but not to all.
I bought a new flex cable/board on ebay. It was supposed to be new but it is obviously used. I have my doubts that it works. I am trying to test it before installing. If I press the power button, pin 10 (as described) should be electrically connected to ground, right? This is not the case with the board I have. Is the connection between pin 10 and the switch a direct trace on the ribbon cable or is something else involved? is there a diode or anything else in this circuitry? Does the battery holder come into play?
Other information. My phone does power on with the charger/remove/replace battery trick. All other buttons work.
Hello to all fellow i9305 owners
Can anyone out there confirm that any of the existing wireless charging mods on I9305 lte actually works?
The reason for my asking is that the my usb charging socket started to show signs of wear and tear . Basically my phones socket became very sensitive to any standard micro usb charging cable. Sometimes it works but 50% of times it doesnt. (I have tried four different cables)
The only cable that works 100% is the MHL one (HDMI-out with USB-charge) which is slightly longer and goes in deeper into the socket (making better connection). Since I've realized the issue was with the mechanical failure of the usb port I decided to explore the wireless charging methods.
There is a big thread about it (which is locked due to people misbehaving) so please do not post links to mods (I've read them all).
I even took the plunge and I have bought all the gear for palm mod (that didnt work) and the gear for QI mod (that did not work either).
Im beginning to think that either my fone is faulty (but no way of proving it since there is no official Samsung wireless charging yet) or perhaps there is something I need to do with software (custom ROM?).I am on latest rooted stock rom by Lyriquid, BTW
Any help is appreciated.
Thanks

Yes: My GT-I9305 is enhanced using the charging coil, etc., out of a Palm Pixi Touchstone back cover with a Palm Touchstone puck. I used copper tape and resoldered the contact points on the wireless charging coil so that they align with the contacts in the phone. The coil is stuck inside the unmodified original back cover using the white sticky cover from inside the Pixi, and some white duct tape to cover the copper tape extensions out to the contacts. I have reused the metal disks with the sticky coil cover to locate the back on the charging puck.
It charges at about 230 mA through my TPU back cover, slower than normal, but perfectly adequate.
The Touchstone puck is fussy about cables and USB PSUs.

Well, Thank you very much
Your post was very helpful and informative, especially the bit about the 'fussy puck'.
I will try that setup again but with different USB cables and chargers perhaps.
Im guessing there isnt any led confirming that the puck is on ?
Thanks again (thanks button pressed too)
Hi guys,
I've used the palm wireless charger with one of those stickers that you attach to the phone on top of battery. It was working perfect but you have to put the phone with this sticker exactly on the middle of the charger otherwise won't work. If you have a case on the phone won't work either. It takes to much time until it charges the battery (I've had a 4500ma ). You can check if the wireless pad works with a multimeter. Put the sticker on it and check if it gets any electricity. :thumbup:

Yes, now I know I need a sticker. Also as I realised I needed the sticker I thougjt I might put magnets as well too.
Then I tried this all and it was wouldn't work with my flip cover so I've attached the palm sticker to the bak of my flip-over case and put the original backing away.
Now its all brilliant . I have my phone in my case and charging wirelessly with no issues.
Those usb sockets arent really made to last, arent they
Thanks everyone who helped.

if you want a "pre-manufactured" wireless charging solution, you can also go on ebay and buy the Qi wireless receiver pad. it fits underneath the battery door as well and NFC still works. The only thing I don't like about it is that it causes a small "dome" on the battery cover so if you use a case, the more "sturdy" ones like the otterbox or the ballistic or anything that will hold its shape to overcome the slight bump.
apart from that if you're handy w/ modding and such, the palm touchstone mod is also perfect since it's insanely cheaper than anything that is offered out there.

Are you still long for wireless charger?
I have current stocks.
You can check out my Facebook page
Its been like that for a few weeks or so
but today its got really severe cause i have to put a much amount of weight on the charger so it can charge
the problem is not in the charger because it works on other phones
the charging port inside my phone is bent
is there any solution for that?

Resolder micro USB connector or change the SUB PBA board (samsung part # GH59-11676A) for 20 to 25 euros.
It takes less than 10 minutes you change the charging USB port. I bought the usb port from ebay for Less Than nine dollars shipped. Make sure you have the correct revision. on my original part it was printed revision 1.0.
Mine has just started to do this. I rang service centre and they are sending a courier. Its in warranty, as in UK you get 2 years. They'll probably send it back saying I did it but ill let you know how I get on.....
Sent from my GT-N7000 using xda app-developers app
Yep, bad port, just shuck out a few bucks for a new one, just make sure it is stamped for the 7000, not others.
Takes longer to watch a video on how to do it, than it actually takes to change it. Took me about 15 minutes, but I'm use to
working on electronic gear. If you have a small magnet around, place the TINY screws on it, so they don't get lost.
When you get it replaced, look at the pin side of the board that has the USB port on it. Under magnification, flex the usb
port and (at least on mine) you will see the pins coming from the USB port flex away from the pins on the PCB board.
Hi!
First, I'm sorry for English, I'm not professional.
A few days ago I made a working wireless charger for Motorola Droid 4.
What are the benefits?
People says, the original inductive charging cover is not compatible with most of cases.
Who live away from USA, can't use a wireless charger, becouse it is only available (officially) in the US. It is very hard to find on eBay or any other site. Almost impossible.
Very cheap. The original charging cover at US, Verzion is $29.99. (+ shipping, and need a person who ship it to me) It is only a cover, and we still need a charger as well.
So, I found a charging pad with and without receivers. There was a small problem. The receivers are only for Samsung Galaxy S3, S4 and Note. Their connectors aren't compatible with Droid 4, but the charging voltage is OK.
We need to take it to compatible with Droid 4. I looking for a long time, which one can I choose. Fortunately I made the right decision.
I bought that: Qi Inductive Wireless Charging Upgrade Kit for Samsung Galaxy S3
Link here
That is only for $30.10 with EU plug. The package include charging pad, usb cable, 1500mAh charger and S3 compatible receiver, and worldwide free shipping.
The size of receiver unit is compatible with free space of phone. We need some cutting but it isn't horrible.
First, I recommend you try, how fits the module in your phone.
Then mark with a felt.
The electrical connector pins are big, (and incompatible) we need to remove it carefully. I used a rework station with hot air (360°C) but you can use a medium sized soldering iron. I think, about 50-60W of power is enough. It took for about 30 secs per pin.
It is important, you need to place the receiver in such a manner, if you remove the back cover, the S3 and some other text need to be visible! Otherwise it will not work!
You see backside of the phone, and the camera is on top. Removed cover. In the right side, you can see four copper pins. The top row is irrelevant. We need tha bottom row. In the bottom row, on the left tere is the +5 V pin. On the right, there is a Ground pin.
We need to make contact between +5V pin of the phone and the +5V charging pin of the receiver unit.
Place the receiver unit to the phone, and see what size of copper wire you need. The lower pin of receiver unit is the +5V. We need to connect it.
I used a wire,1 mm in diameter. It is lacquered, I cycled down it from an electrical part (coil).
I think, that half millimeter in diameter is enough, but a found that, and it is recommended due to the relative high current (about 1A).
When you use thinner wire, you can easier take the cover to the phone.
So you need to solder wire to receiver's +5V pin. Please use the minimum quantity of soldering wire, becouse if you make a big knot there, you will have not enough place to take cover back.
When it is done, you can see how can you bend (or cut) the wire for best connectivity with phone's 5V pin.
Now you need to solder a wire to ground, like the previovus one, but not sure, that the two wore have enough space, and we can make easily short corcuit.
For this reason, we will use the iron cover of the SD card slot. This is a very good ground point.
So, one cable will go down, other is go up. They can fit and the soldering is more easy.
PLEASE BE CAREFUL! I recommend, before you make any electrical or hot operating you need to put an aluminium foil or an iron plate to top of the battery. I think to taking out battery and then in, is not easily possible, becouse after soldering there are the receiver. The battery can damage and explosive! The plastic parts of pohone can tolerate the heat for sort time! If you can not solder succesfuly, you need to wait while the parts cooling down! I recommend, use flux and/or high quality of soldering tin. Take out the SD Card! Please don't make short circuit!
It is not too difficult, but you need to be careful and attentive.
When the soldering done, you can try the charger.
Before you can take cover to phone, you need to cut the lower center of receiver. (you can see on the cover, exactly where. There are a claw and on the phone there ara a hole) Important! We need all of holes on phone, so the wires must not hang in to holes.
I cut the piece of receiver unit from lower left side, at the speaker.
Thats all. We are done. I think it longer to read than make :cyclops:
I made some pictures, I will mark these and upload in short time.
I'm going to measure the charging time with:
1,5A USB charger (direct cable)
1,5A USB charger with wireless charging pad
1,5A USB charger with wireless charging pad (phone in a 1 mm thickness of Trident case)
0,5A standard laptop USB (direct cable)
0,5A standard laptop USB with wireless charging pad
0,5A standard laptop USB with wireless charging pad (phone in a 1 mm thickness of Trident case)
I use that from 3 days ago. It works correctly. By the factory, the charging current is 1000mA with the 1,5A charger. About 66% of efficiency.
The USB charger's stand by consumption is 0,4W.
When the charging pad is connected and it is in stand by mode, the consumption is 0,98W
I'm going to bring images, and refresh the post, but here (Hungary, GMT +1) the time is am 2:31.
Good luck guys!

That great way to charge the phone. i know that my usb plugin is getting a little wore out.......glad to know that there another way to charge up the phone in case of emergency. Congrats.
Hi,
thanks, it works for me
My IQ receiver was a bit higher, or the battery, so I had troubles to fit it in. My solution was to cut every superfluous piece and pull the uper layer of slide away. Additionally, I put it a bit nearer to the camera, The last thing was to horizontally cut the gold contacts and solder the wire directly on them.
During charging, the usb charger+pad+droid 4 use 7W, without the droid 4 the pad+charger draw 0,4W, both measured at the primary side ot the charger.
Best regards,
mifritscher
Thanks for the info, looks promising I love your using Micro SD casing as GND
BTW the pad + receiver can be found at eBay for as low as US $12 Gonna try out for myself soon.
Did you get to measure the charge times?

Charging times are about equivalent
Different approach, same result
Hi, thanx 4 the great idea.
I took a different approach to install the charging pad. I felt not comfortable to solder directly to the phone, so I used copper-tape, capton-tape and some short wires I took from old headphones to mod the pad directly into the back cover of my phone. it got a little bit bumpier (half a mm), but it charges perfectly.
I applied some solder to the ends which connect to the pins, so the copper wont oxidize and the connection has more pressure.

That's a nice solution, and pretty much how the "real thing" was probably set up. I noticed that the back has an internal indentation where the pins are to accommodate the connector, and I had experimented with how I might fit a charging pad in there (actually, it was the connectors that I saw as the biggest challenge), but didn't manage to get anything that I thought was robust enough (I was using cut down parts of a SIM card for the pins to make contact with - you look to have done a better job with the copper tape.
I'm really surprised that we can't buy a new back with all of this gubbins already installed - perhaps you should manufacture a few?
mugen 3800mAh inductive charging cover required!!!
i'm tempted to try this myself. the droid4 keeps getting better.
i just experimented with cardboard, seems to have plenty of room between the cover and the battery. i definitely need inductive charging.
Update 2016
@zuloo.de
Hi! I copied your method for wireless charging but I was too lazy for soldering. That is why I used only copper tape. I ordered under 5$ charging pad and receiver for Galaxy S3 (cheap from China) and it is working good. My receiver says that it can output only 0.8A so I guess it is little bit slow. Can you tell your feelings about the heat? I think that my Droid 4 is pretty hot but I never used wireless charging on other phones so I don't know if it is normal. But thanks anyway posting your method :good:
Here is pictures. I tried to take picture about the bump. It is not bad but you can feel it.
