USB CAP

Hi, there are lots of posts about damaged USB ports. I was wondering does anyone saw or uses any cap for USB. It should be something like rubber SD cap. Just plug it into USB and you can reset the phone in complete darkness . And it could be attached to leash loop with little thread not to lose it while on charge/sync. That would also prevent dust from accumulating inside USB port. Anyway I couldn't find anything like that. Maybe some DIY ...

I was thinking the same thing cause i am having to replace my tilt due to breaking the usb port with the stylus. I would love any ideas on how to do a cover.

bump..
sounds like something that should of came with the phone..

This would be a great idea since I have to realign my usb port every once in a while. The only way I can sync with my computer is by using the HTC USB Headphones adapter that came with my 8525. AT$T said that they would not exchange my Tilt for a new one because bent pins are not covered under their warranty due to "personal damange". It's really weird that I can't use my Seidio Cradle to sync with my computer anymore since it has the same proprietary USB jack. It will only charge the unit and if I move the Tilt while plugged in to the cradle, the connection is not always consistant.

Haha. I thought I was the only one. Went to do a soft reset, wasn't looking, and stabbed the USB by mistake. Didn't notice it wouldn't charge until the next day. Fortunately, I was able to bend the pin (GENTLY) back into place and it works again. BIG sigh of relief

My Mod: Extended 2400mah battery with induction charging

I didn't buy the HTC extended battery but one from amazon sold by Karen Deals. Link is below

Part No: 35h000128-00m, ba s400
Rating: 3.7v 2400mah
Lithium Ion
Induction Unit
Palm Pixi charging back with Palm touchstone charging dock

Images are attached below!
Induction charging has the same charging speed as plugging it into a wall outlet. Very fast!
Sidenote:
I tried using a multimeter with the 3 contacts located under the battery and could not get it to register anything (with and without the charger plugged in). I then tried shooting 5v through it using 6 different combination (2 plugs for 3 contacts) and still couldn't get anything. If anyone knows a way to use these 3 contacts for charging please leave feedback. Also if anyone can find a minature microusb male connection that'd be great.

Well done, it's a really nice mod!
The 2400 mAh is a bit too bulky for me, though the extended uptime must be awesome. I'd even consider something similar, were it not that you're using the microusb to charge. If only you could connect it straight to the battery, would be so much more convenient. It'd still work in for instance car kits and attached to a pc.
Never the less, well done.

Looks great, i would try this myself but i cant stand the bulk of extended batteries and the stock metal back would almost defiantly interfere with the current. Where did you get the decal from?

You can't plug in directly to the battery since the battery doesn't have a balancer board on it and it would explode if it were to be overcharged without one.

I got the decal in the automotive section of Walmart. It came with 2 big/4small stickers for 7usd
UPDATE: Made the microusb head smaller! Letting liquid electrical tape dry then I'll post pics.

this is a really nice mod. what about the possiblly of going via the nav panel connectors instead of micro usb. this would as far as i know leave the usb port free and also not have the disadvantage of having a usb connector attached which can be easily damged.
Personalyu i wouldnt do this mod as i use my phone to tether a hell of a lot so it seems pointless to me, but being able to just sit your phone down and have it charge is awesome.
Great work!!!!

I tired the navpanel connections with no success. If anyone has a multimeter please try to do it to theirs (with charger plugged in).

that is really odd....only think i can think of is manye theres something that needs to happen with the middle pin.

nice work i think that decal are very cute indeed!

PPL this is knowed from a long time! This pins are used for example with Car Kit like CU s400: http://www.slashgear.com/htc-hd2-cu-s400-car-kit-gets-priced-detailed-coming-december-1360143/
This car kit is in two versions: like this on 1st photo - use other battery cover which use this "mysterious" pins to run NaviPanel and charging battery and 2nd version with charging via microUSB port.
I hope this helps a bit.

This "odd" middle pin you can find in every phone battery too. If you depart any battery you can find there a little electronic circuit.
I think, that this pin is used to metering battery charge, but i can be wrong - im not advanced in electornics.

I'm well aware of the existance of these products but cannot figure out what the three contacts below the batteries are.

Maybe some users having one. In that case he/she can make photos of all connectors or better - check it with multimeter which connector is +, - and this middle one.
Maybe some service manuals can tell something more abt this. I searched for it and i did'nt find nothing useful.

I also did a search on google and xda but with no luck. I don't think it inputs 5v into the machine since I did shoot 5v into the 3 connectors using different combination.

Hi all,
The contact closest to the center of the phone (looking along the longest axis of the phone) is the +5V, the one furthest from the +5V is the ground, and there's a small voltage on the center contact, positive to ground. These +5V voltage shows up (on my phone) only when the mini-USB charger is plugged in.
I've got the +5V terminal of the Pre plate attached to the +5V contact on the phone, and the other one attached to the GND contact. Inductive charging works at 341ma (as measure by the hardware and read by BattClock) at maximum, which is probably not coincidentally also the limit set on USB charging, at least from my laptop.
I tried hooking the Touchstone up to a Apple ~1" cubed charger, didn't get any charge. I haven't read the USB power specifications, but according to the people at the Palm forums you have to have a USB spec power-capable charger to initialize the Touchstone, and the USB ICs signal this by connecting the two data lines. This can be approximated by clipping a USB cable and twisting the data lines together on the Touchstone side of the cable. This allowed the Apple charger to power the Touchstone.
The HTC stock charger works fine, as does an 800ma Verizon charger I had laying around. I tried hooking the Touchstone up to both a [email protected] switching charger and a 5V 8A supply, the Touchstone still charged at 341ma. I'm guessing this is software, firmware or hardware limited, just like the computer USB connection. I would speculate that if you shorted the middle pin to the ground pin, it might remove this restriction. Or fry your phone, I didn't try it.
There's a guy on the Pre forums who got the Touchstone to consume about 1.02A (http://forums.precentral.net/palm-p...b-adapters-touchstone-dock-2.html#post2020491) so the thing can, apparently transfer some power. I don't know how long it would last at those wattages, but I'm going to read a bit on the USB power spec and see if the 341ma limit can be lifted.
It's kind of nice to use the internal connector, because it leaves the microUSB port open. If anyone has any questions feel free to ask. With the relevant portion of the Pre cover stuck to the back of my phone, there are no wires out of the chassis and the added part doesn't add any considerable bulk to the phone. It protrudes less than the camera.
Anyways, hope this isn't a thread-jack or too long, but I figured it might help anyone that's going to take the time to do this.
Thanks to the community here.

Did you dremel and hotglue the plastic case to the metal case? Interweb highfive from me to you!
Can you post pictures of the inside wiring please?

I did. I basically cut out a square from the HD2 back large enough to hold the coiled length of wire that is needed to allow the back to be removed and articulated. Then I used Super Glue to fix the section of the Pre back containing the inductive coil and circuitry to the HD2 back.
If you're trying to maintain your warranty I might suggest DigiKey part number 478-4687-1-ND, it's from the AVX "MOBO Spring Contact Interconnect Solutions" catalog under battery connectors (I can send you a .pdf copy of the catalog, it's too big to upload to forum). This is a 3mm pitch connector that should mate well with the internal connector - but - I don't have calipers so I would measure before ordering. I just soldered the wires to my HD2.
I'll post some pictures soonish.
And yeah, high five for sure. Thanks for pioneering this. My last phone was retired when the power connector became flaky, so it's nice not to have to worry about the contact wearing out.

Ur mod is on a dutch popular website!

Right angle micro-usb
I'm looking to do the same thing with my Vibrant and have been searching for a similar connector. I just did a quick google search and found these angled connectors:
http://www.usbfirewire.com/u_microb_cables_angled.html

I tried soldering it your way with no sucess
Soldering pins are as shown
(If viewing vertically with top up)
(leftside of hd2) negative x positive (center of hd2)

bumping an old thread to see if you've taken pictures of the contact points yet.

Sorry it took me so long to reply. Two pictures, the first is the terminal with the wires soldered in, the second shows how I got the cables from the Palm coil/board through the cover. The terminals as you look along the longest axis of the phone with the microUSB plug closest to you are GND, something, and +5v.
So from left to right: 1 GND / 2 ? / 3 +5v.

help pls, phone not charging ( not battery point)do i take phone apart?

need help please people.
my phone hasnt been charging properly for a few days now, to get it charging now i have to get one of my missis hair bands and wrap it round my phone and then round the usb cable so it stays in , although today it doesnt want to charge at all now .
ive noticed that the connection in the phone is loose and you can move it round a litle bit,
now the bit i need help with , is do i take the phone apart and try to fix it.?. im thinking of doing this but unsure about taking phone apart ( dont think my phone is under warrenty anymore,) and im guessing the usb connection on the phone is fixed onto a board.
is it worth me trying that or should i just take it to a repair shop ?

take a dry toothbrush, give the usb port a good scrub. dirt often builds up in the bottom of the port and stops the usb plug pushing deep enough to get a good contact.
Have a good inspect of the usb port, bright light and magnifier is good, see if you can see buildup, or a bent connector, or somesuch.
Also look at the usb plug on the cable, its uncommon but not unknown for the metal outer enclosure to open slightly, and make for a weak contact.
Sometimes a cable simply doesn't fit well for no obvious reason, , i have a generic cheap ebay cable that will only work when angled up or down, like yours, but looks perfectly fine, and feels to fit the socket, while the HTC cable works perfectly, so i know its not the port.
If it all looks good, then chances are you have a dodgy connection from the usb port to the mainboard, which will get worse every time you wiggle and bend the cable to get it to work. In this case, you COULD try a repair, but there have been reports on here of some repair shops pronouncing it too fiddly to replace teh usb port, and a new mainboard would be the only other option.
edit - just reread your post and seen that you can wiggle the port. Broken solder, gotta be. Its not an easy solder, so if your a dab hand, then go for it, if not, see above.

Hi iainbp, heresandyboy had this same trouble in http://forum.xda-developers.com/showthread.php?t=903977 from post 16.
It looks tricky!
Just a thought though, I recently bought a cheap phone charger with multiple interchangeable heads for different phones. The microUSB one became difficult to charge with and it took me a while to realise that the metal bit at the end had detached from its plastic casing, and when I plugged it into the phone it just got pushed back into the casing. (got my money back)
Possible with yours?

USB connector not sitting snuggly in the USB port?

Occasionally since I got the phoone I've noticed that the audiobooks I've listened to have suddenly stopped, and prompting me to press play again; it always seemed to happen when I had a hand in my pocket, so I probably just assumed I had touched the screen or something. It was annoying, but I just continued on.
Then late last week after it happened while I was at my desktop and just moving the phone, I investigated a bit more closely.
I found that I could wiggled the headphone USB dongle, and the fit was not as solid as you'd expect (of course, I hadn't really checked this earlier, just putting in and taking out USB connectors up to this point). As I wiggled it, the audio would stop as if my headphones were disconnected and reconnected. Which must've been what had happened before.
Then I checked with my charging cord. Same kind of fit, I could wiggle the connector a few degrees. Enough for me to raise some concern about it being a faulty USB port, or it having somehow gotten loose in the shell.
This is probably RMA worthy, I'm guessing. The question is what will OP do? Replace the whole phone? Repair it (repair what exactly, I'm wondering)? I've not dealt with their support before, and I couldn't really find any suitable thing under their repair service categories.
Could some people check how snug their USB connector fit is and report back to me, so I could find out if this isn't how it's supposed to be?

First check your USB port for lint. I typically use a needle to clean mine out (Don't short any of the pins if using a metal needle). Lint will prevent the cable from fully seating and cause it to feel loose.

The USB port is totally clean. Couldn't even spot any dust particles under a bright light.

I know the 3.5mm headphone jack isn't technically rated for as many cycles as a USB C connector but I still feel it held up to abuse like being in a pocket better than any type of USB connector.

Desperate need. Crashed my bike. Phone started flickering now its black.

It charges. The alarm goes off in the morning. But the screen doesnt respond and at first it was flickering toward the bottom. Now its black.
Ive torn it down about 50% and dont see anything wrong. The connections seem fine.
There are three photos on the phone I must have for work. Must.
Ideas on repair? Or data recovery? When I plug in the usb to pc I hear the noise and I know its asking 'charge', or 'transfer files'. Without screen response I can do nothing.
Any assistance to get it working or data recovery would be hugely appreciate.
Edit: The glass is not cracked or broken. Ive dropped it literally 100 times. In the first month I fell and sat on it breaking the back cover. I replaced that. That was 2 years ago. Some background of the device.

otg usb c adapter. I have the usb c cord. otg adapter is something I need to get I take it. Thanks for responding.

The important thing is you're ok. Lol, all my bikes are worth more than my phone... I hope yours isn't too damaged.
Try disconnect/reconnecting the battery and reboot; a hard reboot.
If you're lucky a ribbon connector, or ground pathway was displaced.
Either the display is damaged and/or the mobo.
The BGA chipsets can't have their solder joints inspected and even finding visible solder cracks is difficult on surface mount components. High G impacts and excessive flexing can internally damage chipsets, solder joints and multilayered PCBs.

A damaged lcd will flicker, not respond and go black? The glass is not cracked or broken.
The glass and digitizer are one piece it appears.
Amazon.com
So far Ive found no ribbons disconnected. Ive inspected as close I can all visible connections. Nothing stands out.
A lcd arrives tomorrow. So well see if I get a response when I plug it in...

Like tv, if you punch lcd it won't shatter, the crystal will flood or it just flicker, so yes it doesn't have to be damaged visibly to be broken

The battery may have been damaged, keep that in mind. Make sure the phone has enough voltage and current to run.

XDA is awesome. You guys are the best. You may have thwarted an injustice. Saved the files. New lcd heated and I have clamps on it so it seals, hopefully. The frame was slightly bent which was making it hard to keepit on. Im on the home stretch I think.
edit: What to do with an old lcd...
Next project - unbricking an lg stylo 4 with the ch.co message.
