usb connector broken

hi. is there someon in germany, austria or italy who is able to repair my
polaris?? the mini-usb connector is broken, I can not charge the battery or
get any connection.
I have found only one address who offer to repair the usb connector, but I do not want to send my polaris to USA to get the service.
please help if you have some tips or ideas.
thx

Sorry I can't help you, just wanted to say a had the same problem twice - fortunately my provider replaced the hardware without problems.
Good luck anyway!

Broken Mini USB
I just had this same problem with my Cruise. It is only 4 months old and I sent to HTC for warranty and they wanted to charge 400 to replace the motherboard and usb plug. They claimed it was abused. They need their heads examined.
HTC has bad customer service and warranty.

Hi Brunner, you might want to try http://www.mobilephonerepairs.co.uk/home.asp . They are based in London, UK and sending to/from Germany was no problem for me. Just mail to [email protected], explain your issue and ask for a repair price quote.
So far I have only bought a replacement LCD from them and not used their repair service - but will do so next week. Anyway, they were friendly and supportive, and the LCD arrived in good condition and well packaged. Overall a very good impression.

i have some expirience with HTC repair, and can say that the most problems in HTC are in main board - very unstable connections with chips and pcb.
try to tense unit left and right side while usb is connected.
one more - switch off unit (take off battery and pull in) and connect adapter - i am sure in this mode charging will go - this is separate chip doing this automaticly ,but when processor running can sw it off. Stay 1-2 hours and battery will go full.

thank you for your replies... I'll try to contatct the london adress (big thank to doctah).
to romensat: thank also for your , but it is so, that I am not able to connect the usb cable at all, because the little plastic peace into the connector is broken out an some pins are damaged.
regards
brunner

just curious: how did this end up?

wifi amplifer for HTC HD2,is it possible?

I have an htc hd2 I wanna amplifer my wici signal,anybody know is it possible?I bought a wireless usb adaptor for my laptop it is call Gsky 500mw.it is able to get 10 times mor signal and stronger than normaly.Can i do something els with my htc?
Thanks a lot!

good idea, but the current amps use to much power for it to work for long periods, wifi kanes the battery anyways and adding an amp to it would just kill it an hour ot two.
but...
you can make sure that your using the full power of builtin wifi by making sure that it isnt set to battery use over speed
my tg01, and my old diamond, i had the option to change the power of wifi for better battery times versus faster transmission and connectivity.
have a mooch around if you havent already done this, its on the powersave app normally. or performance?
or...
you could make an external antennae of sorts, it might work, but getting like 2 feet of copper wire and twisting it so it looks like a rectangle and affixing this on the back of your phone somehow, the phones wifi might gain more amptitude if can piggyback on something....or it might restrict your wifi usage somehow? i dont know,
have fun

No any plug for antenna at Back of my phone.It has only 1 micro usb 1 for the head set.I dont care if its eat my battery so fast I'm not gonna use my internet for long.And I dont care if a nedd to plug 2-3 feet cable.Because I wanna reach a wifi ruoter what is maybe far away from me.Thanks a lot!

no there wont be an antenna plug, youll have to take the back off, and remove the metal plate to access the htc wifi adapter, and solder or otherwise hold an antenna cable to that.
by the way, this WILL VOID your waranty. also its not the easiest task going...

kk most phones dont have wifi ant. plugs as they are not needed
but...
i remember seeing on ebay some time ago these little clear stickers with some copper wire etched into it to boost the 2g/3g signal, these were not directly affixed to the phones arieal in anyway, they literally were stickers you put under the battery ( so they are close to the phones builtin radio) and they boosted signal that way.
maybe a similar thing would work? if two wires are close enough but not touching they can both share the same signal ( try this with speaker cable,it works)
it works because all cables emit a sort of interference (apart from the noise free type) and if these interferences mix you get mixed results but maybe it could enhance your signal.
we need some experiments on this i think, anyone up for it?

So it is not gonna work,if I get an USB wireless adapter with antenna and plug it in my micro usb?And if I don't need it,I just unplug it.Or any other chance to get a strong wifi signal to my phone.What if I get a portable wifi router and I amplifer signal with this.I hope you understand what I'm wanna say.Or maybe it is not possible?I bought a yagi antenna and I plug it to my 500mw Gsky usb wireless adapter and the wifi signal is more stronger.How can I get my phone work with this?

you cant use a usb wifi adapter as your phone has no drivers, and never will do.
as for using an amplifier attatched to your router, or a seperate one, this will work reasonibly well.

You can look at http://www.cell-phone-accessories.com/htc-hd2-antennabooster-magnetmount.html
I don't know if it works fine. Only I' ve seen this site.
Also:
With my LEO I obtain the max WiFi connectivity removing the back metallic cover and taking the phone with my hand at the bottom half of it.

HD2 (x2) or Touch HD as rear view mirror...

Please be gentle with me, it's my first time, etc etc...
I have a tandem bicycle, and me and the g/f often go off on longish daytrips. It is in the design of most tandems that the shorter person has to go on the back. This means that they can see nothing forwards at all. As she does the navigating this means I have to keep up a constant commentary of what junctions and landmarks are coming towards us while she tries to tally that with the OS map.
I have a pair of HD2s and an old Touch HD with plenty of spare batteries, car holders etc.
I would love to find a way to use a remote camera on the front of the tandem and let her use one of the HD2s as the screen, especially as it has CoPilot live on it which would make the navigation much easier. (I know I said rear view in the title, but I suspect fewer people would look at the thread if I tried to put what I really want up there, and it's no different really.)
I understand that the 'phone's usb ports don't have the required hardware / software to allow me to plug a usb webcam into them.
I suspect that the way forward is to use one HD2 on the front as a bluetooth camera and give her the other as the display, but I doubt that this will be easy, and it will use way more power than a hardwired system which is an issue on a 'bicycle. It already weighs 1/5 tonne with the two of us and some touring gear, so adding a big central power supply would be a shame but is probably inevitable.
There was a brief thread on this on XDA dev in about 2005:
http://forum.xda-developers.com/showthread.php?t=243337&styleid=15
but it never went anywhere and will now be completely out of date.
Hopefully someone can help or point me in the right direction. Sadly I have no coding skills at all, so it needs to be off the shelf h/w or s/w...
Thanks for reading

wow...thats one big project you are thinking off...ok, all things cut short, your best bet will be a Bluetooth camera or a wi-fi camera/webcam. for the former, it can be done, but there arent custom drivers that you can just download to support it. even Bluetooth keyboards only recently started working with the HD2. However, what you can do, that will definitely work is a wi-fi based camera. im sure you are familiar with these. these camera have their own IP address and transmit the feed live via a wireless connection. from my experience, it works quite well, but it really depends on the gear you are using. if you are using a good wifi camera(im not familiar with the brands,but obviously the mid ranged ones will be considered good. If you cant find standalone cams, then buy a small wifi surveillance cam), then there will be a stable and lag free transmission. However, to get smooth feed, you need a good network connection. It will be best if you have a fast data or broadband connection on your phone. 3-4MBPS+ will be fine. Then of course, u need to enable your phone as a modem to connect to the camera. I have tried wifi cameras using a wi-fi connection, both on my PC and my HD2. It works smoothly. The cameras were fixed on R/C helicopters and worked at a range of 20m from the modem. Then again, i really have no idea how well it will work for your case. It should be ok, but not sure about 'good'. You can try!
Alternatively, a more compact method will be to disassemble your HD2 right down to the camera and remove the lens cover. Then, disconnect the actual camera from the phone. Get the correct ribbon cable from your local store. I do not know the specifications of the particular cable, but you try going to a smartphone repair shop that sells replacement cameras for the HD2 and take a look at the ribbon cable. Then, you can search for longer ones or manually solder low resistance jumper wires from the connections(there a alot of connections mind you). If you want to do this, please get info on proper disassembly instructions and do alot of research!.
i really admire your endeavor and although it may be hard, best of luck to you and hope you succeed, should you undertake this. Nevertheless, just some small advice...If you are also considering about the budget factor, i think it could be equally expensive or cheap to buy a purpose built remote camera which can connect to a screen.
-cheers

A wi-fi camera on a helmet would give flexibility as to what you were able to view ie could move head to point camera in the direction that one wanted to view
Good luck

Thankyou both!
Sorry I've been a bit slow replying, home internet connection has been intermittent for a week or so...
Kawshigan, can you clarify something for me, when you talk about "fast data or broadband connection on your phone. 3-4MBPS+" are you saying that I should be sending the data via the cellular network? If so that is not going to happen. I don't know where you live but here in Canterbury, a small city in the most populated part of the UK about 50 miles from London, 3G is a dream. There is a 3G service of course, but it is so weak that it is unusable even in the town centre, so trying to use it away from the town for my project will be impossible (and would be very very expensive as we get only 500MB / month here cheaply.)
If you mean forming a wifi connection between the two phones, which I suspect IS what you mean, then surely the speed of the connection is whatever hardware can do, allowing for distance which is about 3' in this case.
I agree that a ready-made system should be a similar price but they do not seem to exist. There is something in the US but it is very expensive ($600?) and is intended more for recording accidents really. certainly it has no nav function. I'm too new here to post links but if you Google on "cerevllum.com" you'll see it, beautiful, expensive & only half the tool I need.
It seems such an obvious thing to do with a smartphone (the rear view camera I mean) as mirrors on bicycles don't work well, and most of the components seem to exist, it just needs someone to tie them together.
I suspect that putting an external camera on my Touch HD is beyond me. My soldering skills are ok, but surface mount stuff is beyond me, not least because I'm 45 years old and my eyesight isn't up to it anymore...
But then again, even as I type this I realise what you actually mean, is to mount the HD2's own camera remotely at the front of the bike and run a long ribbon cable to the rear handlebars. Now THAT is a GOOD idea. Probably I'd start with the Touch HD as my HD2 is still my everyday 'phone and I hope to keep it that way for ever. When I get some time I'll pull the Touch apart and see if it is possible. How long could the cable be before s/n & voltage drop problems etc became too much, I wonder?
The helmet cam doesn't really work as the problem is not so much positioning a camera, (I can do that on the handlebars) but how to get an instant display of what the noggin-cam is seeing onto the screen of a smart phone? The problem with the helmet cam is that I think the viewer would have the same problem that you get watching YouTube videos where the camera is bouncing around and rarely pointing in the right place all the time. The Tandem has good suspension at both ends so it would be ok on the 'bars I think. ( Google on "VCA 2010 Race" for an amazing video that shows this problem a little, and no, we don't do that on the Tandem...)

So when you remoted the CMOS sensor...
Did you end up giving the "extra long ribbon cable" idea a try and if so how did it work (or not. Interested in how it came out.

[Q] Connecting to WiFi via external USB dongle - Is it possible?

After having my N7 serviced for being stuck in APX mode, they returned it to me with faulty WiFi antenna. I wasn't in the mood to go though all that trouble the very day I got my N7 back since they kept it for more than a month before they returned it "fixed" to me so I didn't send it back to ASUS again.
So... cutting to the point ... I broke the wifi pins on the motherboard while trying to bend them a little and now I can only connect to a network if I literary put the tablet on top of the router.
I want to know if it's somehow possible to use an external wifi usb adapter to connect to networks and use it as an alternative to the internal wifi.
I know there are some options to make an external wireless device recognized with some kernels out there but not for general internet browsing, rather for developing reasons.

If you know of a Wifi Dongle compatible with USB-OTG and were willing to write the app/driver or kernel module specifically to work with that dongle, then yes it's possible, just a matter of how much work do you want to put into it.
(As there is usually never a reason to plug in an external Wifi adapter when the internal one exists, I doubt there's already a pre-made kernel module for one).

stop oppressing me

Well, I took it to a local electronics store and they said they are able to solder the pieces together. Hopefully I'll have an N7 with a fully working internal WiFi by the end of the day.

If it's working, let us know what the damage ($) was to have something like that done.

Yes, it is working again, though not as good as before I sent it to ASUS the first time.
When they returned it, with a new motherboard, the WiFi reception was not as good. Now, the reception is as good as it was when I got it back from ASUS. So I guess, that's it's full capacity now.
Nevertheless, I can at least be a couple of rooms away from a router to get a reception. It's still a bit dodgy, but certainly existing.
The price was symbolical I guess, since it only took a few minutes for a professional to solder a couple of pieces together. They charged me 3 dollars

I wonder how much they'd charge to solder on a mini-antenna (but bigger or a wire that goes around the edge of the back) or something that can fit there with the back closed down on it. You know kinda like you would with GPS.

I don't really know what the guy did. I suggested that he used single strand wires since I lost the broken pins. But he may have improvised with some other similar pins to make the contact. And I'm not really willing to open the cover and **** it up again.

External antenna port

Hi all, new to XDa so go easy on me here...
Just. Got a smj327p sprint phone
Where I live I get very poor 4g coverage roughly -105dbm on band 41
What I am trying to do is connect an external antenna
The phone has a mhc705 connector labeled r1 which I'd love to make use of
I have a patch lead from my S4 days, This is a ms705 to FME
The cable fits the port but I do not think the center pin is making contact as I do not get any signal changes whatsoever, doesn't appear long enough
I am trying to avoid using a passive patch
can someone recommend a correct cable for this phone?
Thanks in advance

Hey Jer1981,
I'm in the same condition, pls update if you find a solution to plug an external antenna to the J3.
I share here a reply from some antenna makers in New Zealand: "The port on the J3 is more of a 'test port' than a usable antenna port. The port is smaller and more delicate than the one in the link, so much so it's designed for use in a 'laboratory environment' only. I can get the fitting to work with it, but it must be held in place and costs more."
I'm thinking of getting a 3G mobile wifi device from huawei with external antenna port...

Hi what cable are you using? for this as mine doesn't appear to get a connection at all
