Hello,
I don't know if this has been posted here before and i also didn't find any topic related to it, but... what the heck is this Rear-3-PIN-Connector created for?
Does anybody know?

I'm not 100% sure, but i suspect it may be utilised by the replacement battery cover for the official HTC car kit, which charges the battery when clamped on.
Just a guess, though. I have been wondering about it myself.

its for the car mount
GG

does anyone have its pinout?
1 is GND
2 ????
3 +5V
Thanks.

And this plots (both sides), that seem to be connected by the back cover?

I suspect these are to stop the back cover from becoming loose and rattling. if you press them they are spring loaded.

I think the back cover is used like antenna. These plots are used to connect the back cover to the rest of the electronics.

It is most probably for the official car kit. It was supposed to have a different back cover that allowed for mounting on the kit and charging. This car kit however has now changed design. HTC have designed a kit that uses the usb port to charge. see here http://wmpoweruser.com/?p=12298

Would be a shame if they'd bring it to market like this

Need help: USB connector broke, where to get another one?

Sadly, my HTC Wizard/Cingular 8125 USB connector broke off. I'm not sure how it happened but I can only guess the pressure of inserting the mini USB cable wore it's soldered mount points and gave way. I tried soldering it back but when I adjusted those little prongs underneath so it would have good contact with the board, a prong broke off. So I'm out of luck and can't recharge the battery. Does anyone know where I can purchase the identical piece so I can solder it back to the board? Also, has anyone else had this same unfortunate fate?

If you search the wizard forum, you can find people that have spare parts.

thanks Calouro, I'll give that link a shot.
wow, i had that happen to me too, i send it back to t-mobile for repair. but i afraid of it happening again, bc it hard to fix and my warranty expired.
These people do USB port replacements I believe:
http://www.pocketpctechs.com/
Thanks Paul.. checking them out.
I just had the same thing happen...PPC Techs as mentioned above does that repair for $60 + shipping. They mention this issue specifically as a K-Jam fix on their web site.
I sent mine in but they advised they were unable to get ActiveSync working again after trying a number the repair a number of times. They shipped back to me via ground FedEx even though I requested 2-day so I don't have it back yet to test...

They may have induced heat damage to the USB I/O circuit. This can happen if the soldering iron is too hot or left on the contact too long. In addition, if multiple repairs where attempted with not enough cool down time between heating, the USB I/O may have been damaged.
Also, if they did a sloppy job and shorted two of the contacts together on the USB plug with solder by not completely cleaning out the old solder can cause issues.

[Q] Wifi range terrible, does replaced back effect it?

Hi All!
I bought a N4 off ebay that had its back replaced, here is what the listing said, "This phone has a replacement back glass WITHOUT wireless charging or NFC capabilities." which I dont really care about but my WIFI range and GPS is terrible.
I've tried multiple kernels and roms *including complete stock everything*
Its not my setup as my HTC one s, multiple laptops, wii, ipod, ect,ect all work perfect on my Asus Router rt-n66u.
Does anyone have anything I can try?
Also have a thread up for my gps : http://forum.xda-developers.com/showthread.php?t=2365187
Thanks for reading!
Since the replacement back does not support NFC or wireless charging, do you think it was suitable to support any other wireless feature that was designed for the Nexus 4? Does Bluetooth suffer the same reduced sensitivity? If the replacement back is not made of similar materials withsimilar characteristics as the original back it might be absorbing or reflecting signals, interferring with proper wireless recepton.

Well thats my fear,

Looking at this post it looks like whoever replaced this phones cover didn't transfer over the copper attenna's , that would be my guess and would explain my horrible wifi and GPS ... luckily my phone reception is good.
I'll have to open up my back now and take a look... now to have a T5 screwdriver at work..
Unfortunately cant find a t5 here at work , I'll have to wait till I get home.

Looking at this image looks like I should only be missing the top right 2 antennas for Band 5 , GPS, WLAN, BT. I assume I have the other 2 antenna's as my phone reception is good .
Anyone know where I can buy just the antenna's?

Hi everyone,
Now we have holidays ( I love it :victory: ) and a lot of free time. During the school year I studied a lot but now I can play with my lego bricks
So a few days ago I thought about annoying problem with my phone and charging it.
All time I'd like to charge my phone I have to push away my bed, plug charger to the socket and then plug the phone to the USB cable. So I thought I could build a robot which would plug charger to the socket if I turned it ( my robot ) on.
I was building it for three days ( with long breaks for sleep, meals, etc. ) and I think it wasn't easy. I have built also a charging dock for (my) the best phone -> Samsung Galaxy SIII mini
CHARGER NXT 2.0 FOR SAMSUNG GALAXY SIII MINI​

I'm really satisfied with the resuls To build I have used NXT brick, one servo motor, one touch sensor and a light sensor. I used a lot of varous bricks from 9695 and 8547 sets.
How does it work?
If you want to charge your phone you have to only put your phone in the charging dock and turn on robot. When you turn program on, the lamp will also turn on. If it is green, your phone will charge. If it is red, you have to click "PLUG" and then your phone will charge. That's all
Let's see what I have done

Nexus 7 USB Port (Broken Solder Pad)

Hi,
My Nexus 7 Gen 2 usb stopped charging (it was on/off for a while but now fully stopped).
I ordered a new USB component from eBay so I was desoldering the old one this morning but unfortunatley the 5 pins at the back ripped a few of the pads from the board off.
I was wondering before I order a new USB PCB for £40 is it possible to re trace the 5 pins and wire them to somewhere different on the board??
Looking at this picture this is what I thought I could do:

Is this possible and if so the best way to fix this?

You could try soldering to those solder pads right before the resistors/caps in the path. If you bypass those, and solder directly to the exposed pads you identified, you may have issues, i.e. those resistors/caps are probably there for a reason . That's what I would try anyways.
did you ever end up soldering to these pads? cause any issues?

nevermind, didnt work of course. Ended up soldering to the pads just before those caps, just needed to not be lazy about it.

Opened back housing, what do you guys think this metal "clip" is there for?

I was replacing the back housing of Nexus 6p to change up a little for fun, for the second time. The first replacement took place a month ago, from silver (OEM) to black. Since the black housing is scratched quickly without a case, I bought a white one, which came in today.
Upon inspection, I found this metal clip right above the camera cutout (shown in the picture below, it is from my OEM housing) to be missing on the new/white housing. Do you know what this thing does, and if absent, will it pose any issue using the phone? I thought it could be antenna connection at first, but then I found many other small clips stemming out from the board instead of the housing, so I thought those might be the antenna connections. Then what does this clip stemming out from the housing do

This is the clip supposed-to-be from my OEM housing
This is the clip broken piece from the new housing I got.
That clip connects to a contact above the camera as seen on ifixit teardown

Yes, any idea what purpose it might serve though? I have put the housing on anyway, just fear that it might cause some functionality issue down the road.

any kind of connection as such, using a spring clip, means its meant to get signal from A to B. In this case, it seems is something that may use some soft of radio signal.
anything like that missing a connection will surely affect something (is there for a reason)
