Phone struggling to charge.

Hello everybody. Recently, I had my phone go under a repair which involved opening up the entire phone just to replaces the mini usb port, which was detached from the phone and was trapped inside, losing its ability to charge.
Now, another problem has arisen. The phone has problems charging with wires compatible with its port. When I connect to it to charge via usb, it was plug-n-go, all good. For some unknown reason, it suddenly came under the issue that I need to shift the usb up,down, left, right, and slightly bend it the inside. Now, the original charger doesn't work because it broke, leaving the usb charger as the only option. I can't understand why my HTC Wizard is having this problem,and it's very frustrating. I paid sixty dollars for the repair on the USB, and it seems it hasn't done anything except reattatch it. Any suggestions?

Hey Infinity M,
By your description, it looks like the soldering is a bit loose, thus you have to shift the USB.
Have you tried with different chargers and cables?
If you wish (at your own risk), get a thin screwdriver or something like one, then apply a small force to all directions at the border of the Wizard's USB. Watch if it moves with any pressure, as that will indicate a loose solder.
Good luck, man!

Thank you for your sufficient reply. I have not tried a different cable, and I have checked the Wizard's USB. I'll have to try another cable to check if it works. Do you know where I can buy a charger for a cheap price. Thanks!
Edit: Heh, I realized you're the same person making that HTC Obsidian Case, I'd love to pay you for it lol.

That's a hard one. I would send you straight away to eBay, lol, but I guess you can take a look at some local stores near you. It doesn't need necessarily to be a Wizard's charger. In fact, any charger for a HTC device that uses the same battery will do (the Tytn's I guess). Or you can check the charger label and see if it meets these requirements:
INPUT: 100-240V~0.2A
OUTPUT: 5V, 1A (this one being the most important of all)

[Q] Electric shock or tingling effect on legend when charging

iam experiencing a electric shock or tingling effect from the body of my htc legend when charging.it goes of when i pick it up.upon placing it on some surface the same effect returns.iam a new one here,is it a faulty handset.it is there only when charging. please help

I'm pretty sure its a bad handset, a connector for charging the battery is exposed and touching the aluminum casing.

Your power source are not properly grounded.

its nt there when charging from my laptop

Your laptop only charges at half the rate of the AC adapter, it probably still is putting current through the aluminum case, but you don't feel it.

Well, thats because I had similar experience. I used to connect my phone to my laptop with AC adaptor (faulty battery) till one day when it was a goner, I bought a new slim OEM version which do not come with ground (2pin vs 3pin with grounding on stock adapter). Ever since, I have had electric shock whenever Im connecting to my laptop.
I have gotten electric shock when using the stock charger as well. The old wiring at my in-laws house probably the cause for it. It was okay at home.

Are you sure you bought an HTC Legend? Are you sure it's not a defibrillator?

Your phone is just fine, don't worry. The effect your are feeling on your skin is caused by the charger and has nothing to to with the phone. There are some unqualified posts in this thread (e.g. problem with wiring, charging current) which should best be ignored.
To the effect itself. The charger isolates the mains power from the secondary power through the use of a transformer. Also our new small power supplies work with transformers, but operate them at a higher frequency (sometimes audible) after the main power has been rectified. But the power supplies represent also an electric capacity, and therefore the secondary output may charge up relative to ground. But this capacity is so small, that you may feel a voltage on your skin but there is no risk whatsoever. By the way, the back of the finger is very sensitive. Try to move it along metallic surfaces of other device (e.g. desk lamp) and you may fell the electric potential. The only way to completely avoid this is to use a grounded power supply, like some used to charge laptops.

yep. use groundod power supply. i have this thing when charging from my laptop and the laptop adapter is not properly grounded.
dont worry, its normal and negligible.

Yes, keep your Legend and enjoy it...

If i had this problem i would most likely first try an other power adapter
if the problem is gone fine!!!
if not then i would send it to HTC service

I had the same problem for a while, changed the charger cable (Micro USB to USB-A bit) and it fixed it
Oh the comment about a difibrilator..........Nice!!

[Q] Broken USB Port

Soo... I think the USB port on my T-Mobile HD2 is gone. I can feel it jiggle around when I plug in a USB cable... that and nothing happens when I do. No charge, no USB notification, nothing. Not even plugged directly into the power adapter.
My question is whether anyone knows any way to repair the phone for cheap? I've taken the phone to several cell phone repair shops, but no one can do anything without sending it off to HTC. If they do that, then HTC will charge me a crapload because the custom software on the phone somehow must've caused a hardware problem. Because the USB port is broken, I can't flash back to factory, soooo... there's nothing I can do there either.
Any help or advice would be appreciated. Thanks!

My first and only suggestion is to look for the not working phone body of HTC HD2 at ebay.com or similar. If You have some manual skills it wouldn't be so hard to replace it by Yourself. Of cause it is almost open heart surgery but it is possible to do by DIY.
If something like this would happen to me I would do so. You can look for only micro USB port to take it away from other non-working device like old camera or mp3 player or other phone.
Why they decide to use mcroUSB instead much solid miniUSB i don' know.
You can also look for micro USB connector
here

You can put a stock winmo rom (LEOIMG.nbh) on the root of your sd card and boot up into bootloader by holding the volume-down button while booting. Then the bootloader will detect the .nbh and ask you to press a certain button to install it. Then you can send the phone off to htc, it will be completely stock.

Wish I could, but apparently the cell phone repair shop that tried to fix my phone decided to tell HTC about my custom ROM though he told me he would be doing the repairs (only reason I left the custom ROM on there). But they actually decided to ship it to HTC. HTC decided to record the serial number so I can't send back to them anyways. =/
About the DIY repair. Would it just be a case of re-soldering the USB port back on the phone? Or is it something more technical? I'm asking because the cell phone repair shop I tried out said that they needed to replace that entire board. AFAIK, that board is the mainboard. Doing so would require buying another HD2 body, but I'm afraid that would cost far too much as I am a college student with ridiculous school fees and a very low income.

1: aww dude that sucks, they got you by the serial #
2. I have a broken micro-usb too, saw the disassembly vids, and it looks to me that the m-usb port is attached to the mainboard, and you have to consider too that if you try this as a DIY project, people have had wifi coax become damaged, lcd/digitizer damage, who knows what else from 'professional' repairs, let alone doing it yourself.
2 options, get a card reader and an external hd2 battery charger (and preferably a spare battery), or have the micro-usb port fixed by someone else or by your self.
The external charger and spare battery is cheaper by far, i paid only like $8 for each, and it's surprisingly reliable and practical.
Hope i helped

i would totally call out on that shop and demand they fix it, since they ruined your warranty by sending it off to htc without your consent..
also, search on ebay, theres a cellshop in texas that repairs the port for $50, you mail it to them takes about a day and they mail it right back.

That sucks...I feel like the micro USB on my hd2 is about 2 die...if the phone moves at all connection and charge is lost. why oh why did these bums pick micro USB there's got 2 b a reason
To me is a serious design flaw...I mean its only a matter of time b4 the micro USB will fail on each and every hd2 regardless of how much u baby it device (which most of do)...after a certain number of charges the port goes bust
IMO the micro usbs put 2 much pressure on the port itself it's simply not big enough/solid enough of a connection to support the weight of the wire itself and over time gravity loosens and destroys ur port until u can't even.charge

I agree, the micro-usb is crap. Had my hd2 for like 2 weeks and i broke it by the charge cord getting caught on my foot, sending the phone flying. Luckily, i found that i could get a connection to my comp by holding the cable 'just right', flashed magldr and cwr, and just charge my batteries on the external charger now. I was stuck on the winmo 'test' rom for like 6 months lol.

dude same thing happened to me yesterday i was charging my phone and i got up to do something. And the cord caught on my foot and the phone went flying also. and when i tried to charge its like if you move the phone even the slightest it looses connection. But i found a fix that worked for me. im using my external hardrive cord to charge. the connection is a little thicker and fits in there perfectly so now i can move it and it stays connected... Only downside to me is the cord is really short

Yeah, I railed at him for a good 10min in the shop with customers looking (hope I drove away some of his business...). He said that he couldn't fix my phone because I had *illegal software* on it... really? I doubt that a software problem caused the microUSB port to just break off the mainboard.
I've also looked at the disassembly video, and it doesn't seem impossible, but the cost of a micro-usb port is around $35 from what I gather. I think it would take some soldering to replace it, but I have neither a solder nor the experience to attempt it the first time on a $400 device.
I guess I'm stuck with the microSD adapter and external charger for now. ~sigh~ Maybe I'll try another internet-based cell repair shop. Anyone know anything about cellulardr.com? It's based just a couple miles from where I live and they have the part in-stock with a 50% discount that brings the price for repair down to $35 + $35 for parts which is a little high... but if it gets the job done...

I'm a [fraught] example of the result of thinking the usb would somehow last if I was just gentle. Who was I kidding, it was shot to pieces.... I've dropped £100 fixing the phone's screen which resulted in the volume buttons and vibrator dying (I argued till I was blue in the face- before I demanded they reglued the screen back on, a day after it had been 'fixed')... Damn crappy little repair shops, no leg to stand on.
And now I can't charge it.
Waited 2 days for a wall charger (and believe me that was hard as it's my work phone) to find that nomatter how long it's charged for it's dropping from 80% to dead in about an hour no activity.
I wouldn't mind so much but to have finally found a rom I liked, right through from WM to SD android versions to now Cotullas Nand, I'm reluctant to give it up, even though it's more than likely on it's last legs.

If they made these things more reliable, they'd never have a means to convince you to buy another device .

well a usb port repair is totally possible with just an soldering iron, but you will need a fine tip for that and some flue that does not require cleaning. if any of the contact pad came off you better know where they go or find a way to trace where it goes. if they are broken and you find where they are connected you can use a copper wire taken out from copper brace to bridge them. lastly a broken usb port from the motherboard will never be secure again, so you have to put some padding under it so it will not be moved again; otherwise it will break and may take some contact pad with it in which makes it harder to repair again.
I fixed one of these before with only 1 broken pad that I can trace. so it is definitely possible to be done, but it will be very hard if this is your first time repairing phone. it is possible to rip the volume flex cable like I did. It took me 4 hours to solder flex by rewiring copper wires.
By the way hd2 usb port is only 7$ from eBay.
P.S the good thing about fixing phone is that, I got it from eBay, fix up, and working at $120 XD

Phone going crash
I don't know what happen recently with my phone. It just starting crashing on normal activities. I thought it was probably just the rom, but I flashed HyperDroid GBX v12, clk version and damn....i can't even get pass the boot animation. After a while I did...and then I connected my USB to my computer. Within seconds, phone crashed. I need help. I've task29 this kid like 4 times and then installed clk again.

Sometimes it is just the usb cable quality causing a bad connection... I had this Chinese micro usb data cable and it would only work at a "just right" angle, until I went to Radioshack to buy a 27 $ gold plated usb cable lol
Now everything works good and saved me from having to replace the microusb port on the phone.

Woow I thought I was the only one! I feel all your pains man..
First things first, those of you whose USB is still working, get clockwork mod set up before the USB dies.. at least with a card reader you could still flash thru zips.. I got an external charger and an extra battery as well, now I feel like my hd2 was sorta reborn! Haha..
Dunno bout you guys but I'm starting to feel that our beloved hd2 is slowly being abandoned really sad thing.. and I blame the hardware problems for this trend..

Nah, it's just nearing the end of its life cycle. There are better phones coming out now with faster processors and more resources to run bigger software and flashier graphics.
The HD2 has actually stayed on the top of the hill for a surprisingly long time, and in some ways still is.
The biggest difference with the HD2 compared to other phased-out smartphones, I think, is that the HD2 is still very useable even though it is well beyond its originally intended amount of time in the limelight.
I notice this whenever I dig out one of my old devices that I haven't used in a long time, like my Kaiser or Rhodium. They are so slow and basic that they're almost unuseable, where the HD2 is fast, smooth, and seems modern still.
But the mUSB port on these things is ****. Mine's been half-busted for almost a year. I have a wall charger and extra battery, and if I hold the cable just right, I can usually get a connection to the computer, but it's just easier to pop my sd card in one of my old devices to connect to pc and transfer files. The mini-USB ports never gave me near as much trouble as the micro ones, I wish they'd have never switched.

Hi all,
Just thought I'd let you know how I fixed my HD2's loose / non-functioning microUSB port.
I've had similar problems for the last 6 months or so - dodgy microUSB connection resulting in massive amount of fiddling in terms of getting the cable just right, then pretty much completely screwed!
I took receipt of a HTC Sensation a few weeks ago, so decided to spend a little while opening up my now redundant HD2. Dissasembly is pretty easy & self-explanitory, but the leaked videos showing you how to do it is pretty useful. I'm no whizz at these things, but even I managed to do it (mostly) with just a kitchen knife (forgot where I'd put my small screwdrivers, which I eventually found, but everything seemed more dangerous & exciting with the knife).
ANYWAY, I've managed to secure a completely loose microUSB port which means perfect charging & USB connection again. It was incredibly loose & just fell out when I separated the mainboard from the chassis, but I put a bit of rubber I found under it (soldering iron is for pros... I'm winging it here!) & secured the mainboard tightly with screws.
I mean, there's probably a better way to do it, but I couldn't be arsed using any more ingenuity than required... it's a Bank Holiday after all, and the solution seems to have worked pretty damn well.
Cheers,
Dan.

Hi, I can only charge my HTC HD2 phone using the USB port, but I cannot use the usb port for activeSync and USB function (data transfering). I wonder if the USB posrt is dead already?? Why the phone still can be charged via the USB port? Can anyone tell me how to fix this?
Thanks in advance.

I had the same problem last week. My pc couldn't recognize it, but i was able to charge it.. I just took an other usb cable and the problem was solved.

Busted Charging Port

Alright guys?
Accidentally leaned on my phone the other day whilst it was charging. Seems to have bent the charger port on the phone.
The phone still charges ONLY if the charger is plugged in and propped up in a certain way. needs to be pulled up slightly or there's no charge.
USB drive nor ADB work anymore so i'm guessing that a circuit has broken...
Does anybody know how these work?
If it's a case of broken connection, perhaps putting phone in an oven for a few mins will melt the the solder and hopefully fix the connection? (This worked fixing my 8800GT graphics card few years back!) Long shot
Ta
If it's truly broken then i'll probably get an SGS and then take a hammer to the HD2

The micro-usb port on HD2's is flimsy. It's probably snapped off from the mainboard, and putting pressure in the correct way is pushing it back together. Same thing happened to my HD2.
But there is some relatively good news. An external charger and an extra battery will only cost you about $16-18 USD on ebay. This has worked just fine for me for over a year. With dropbox installed on your phone and comp, you rarely have to connect via usb anyways.

if poss, check with another cable first.
I have a usb cable that looks fine but will only charge when angled downwards, no data, , yet if i bend it upwards it carries data but wont charge. my other usb cable works perfectly.
chances are it IS the port, as said they're pretty flimsy, however best to check, be a shame to bake your phone for the sake of a £2 cable.

same thing happened to me a few months ago,
the usb in the phone broke,
so i got a mains battery charger from ebay for about £4 and a few extra batterys,
been using them now for bout 2 months and all is good again,
it was a pain trying to get the usb in the right place for it to charge , i tryed the oven thing and it didnt work , not sure if i left it in there for long enough but i didnt want to ruin my phone completly.
easy option is to buy a mains battery charger

Thanks for the replies!
I'll look into a mains charger and 2-3 more batteries

So after my phone failing to charge at all last night I popped down to the local phone shop / stand in town and bought a universal battery charger.
+ and - aren't labelled on the charger so I assume it doesn't matter or it works out which is which?
It's a little slow and was a bit pricey, either way I have 63% battery now after a couple hours
Thanks

Wow mine's at 100% after a couple hours

Well yes, that's a workaround. You can still buy a Qi-enabled back door or just buy the paper that goes conected to the pins and place it between the battery and the back cover itself (I don't remember the name, but there are a lot in Amazon or Aliexpress).
By the way if you want this phone to be your daily driver, I suggest you to get it fixed. Wireless charging is painfully slow, phone cases doesn't fit with aftermarket Qi enablers or even the genuine back door and they probably don't work with the charging base either. Also with WiFi you wouldn't be able to transfer files or even flash roms between your phone and your pc as fast as with an USB cable. Now if it will be your secondary phone then sure, grab a Qi cover or get an external battery charger and problem solved. Good luck!
