inductive charging?

anybody know what the pins on the back of the battery cover are for? it looks like what you would find on a phone capable of inductive charging. if so, anybody figure out how to do it?

They act as an antenna, dont **** with them

hmm ok. ill have to try it with the cover off to see its actually the antenna but ill take your word for now.

it does when i was playing with my phone without the backcase on i had no service

I only get 2G service when the back cover is off. I think it has something to do with the antenna as well.

I actually was wondering what the pins were for. I just took my back cover off and immediately dropped all signal.

thats kinda weird to have an antenna in the back cover. maybe they plan to release a new back cover that will improve strength? i cant seem to understand why.

Its just the design. And it saves space on the device.

Its definitely the antenna... and i personally think it was a brilliant design!

inductive charging would be great for our phones, i know the palms do it!

So anyone want to do the palm pre inductive charging hack. I think it has been done on a hd2

HTC states that the battery cover of the aria is the antenna on their website under troubleshooting:
My device shows “No Service” but I know that there is coverage at my location. close
The antenna for this device is embedded in the battery cover. If the battery cover is not installed correctly, securely affixed, or if it has been damaged, this could be the cause of the device not picking up on a signal.
You can find this on www(dot)htc(dot)com/us/support/aria-att/help/phone

i tried, they wont cover accidental damage. And my warrantys been voided since someone opened it up..

I bought a second hand phone and it did turn on however there were a numbers of problems with my phone, it had a power button that didnt work, unresponsive parts on the lcd and a quiet in call speaker.
Your best bet before trying to replace the whole pcb is opening your phone using a teardown guide
http://tjworld.net/blog/htc-desire-z-tear-down
Make sure you read it a couple of times and go through the pics so you know what your dealing with, find the power button, make sure its intact and adjust the ribbon cables.
Otherwise just find a cell phone repairer on a classified ad like criagslist or kijiji.

I hate to say it, but it was second hand for a reason. Ever try switching the battery? How about changing the power supply?

Yes. Start simple. First check your electron hose to make sure you are getting power to the device. Also check the battery as well as the prongs that connect with the battery tabs. If things are good there, then think about tearing into the phone.

no no, dont say that. This phone was fine for 3 months, i dropped it at a club i went to and water got inside the phone....i took it to 3 repair people and they all said the Main PCB motherboard is damanged (water) soo does anyone have any idea where i can find a motherboard?? i have no problem with costs of replacing it. As long as its not more than the phone itself.

You didn't mention water damage in the OP. You said something was loose. Water damage is completly different.
Try ebay.

Hey i found these 3 ads on ebay...do you guys think that a swap of the motherboards would be fine? heres the ads. I contacted the seller and they said the battery was used and thats it but phone seemes operational....i know its a risk, but is it worth it guys?
..need help on this one.

why swap the motherboards if the new phone is working fine. Just transfer data and you're done surely?

Reason being the other phones have minor problems, like speaker doesnt work, or some of those phones wont pick up signals and i think thats due to a bad radio flash or if i just flash a radio everything should be working fine.

can someone please clarify this? if i buy a phone with a speaker problem and transfer the main PCB board to my old phone...will there still be a speaker problem? or is the speaker a separate unit itself and not related to the pcb board?

one of the phones i am bidding for says it might not be able to guarantee a connection to mobile network (send sms,make calls) could that be a radio flash problem? would i be able to fix that??
another is one of the phones boots on and shuts off, i take it that could be a bad flash or something? its only about $20. just trying to weigh my options cause the new phones are lkike bidding for $350 lol im not that rich yet

I found out that my MOTHERBOARD is fine. There was water damage but not enough to go inside to the main board! My dad tested the battery voltage and found i wasnt getting any voltage.
i went to future shop and found a lady to let me use her battery and sure enough the battery was working and phone powered on!!! so i guess my battery was shot from dropping and popping out of phone while recording a video.

ordered these from ebay....are they any good? they look decent

Those look like the batteries I got. They were about 1/2 of the claimed mah rating. Worst case, they wiill get you running, and that charger is pretty good.

[Q] USB Port Fix Solution

Ok guys I bought an EVO 4G off of ebay and I've fixed everything on the phone except for the wonderful USB port that fell off.
Now it was a pretty clean break so it didn't pull anything off of the board. Since I'm on MetroPCS I can't provision the phone completely without fixing the port.
My question would be this, since I don't have a micro heat gun to heat just this area on the board, do you guys think the oven trick could possibly work on the phone to melt the solder enough and reconnect the usb port?
Would it mess up the camera or anything? Not sure, I need some suggestions to see if this would be a stupid idea, a smart idea, or should I just cut my losses and re-sell?
I need help ladies and gentleman.

IMHO..... Hell No. You are gonna fry your evo.
I wouldn't resell, but get it fixed. I found a place nearby that put an OEM usb port back on my evo for $35. Warranty and all and I am back up good as new. My suggestion is that you find someone with the tools to do it right - otherwise you could lose it all.

Where is the place you found that did it for $35? Is it in South Florida?

As an electronics major, you'd be slapped for suggesting that.
I wouldn't recommend it because it MAY be enough to melt the solder, but other smaller components on the board could fail due to overheating, and the camera would most likely crack or fail completely.

LOL yea I figured, but it doesn't hurt to ask cause it does work for computer motherboards

Well I've never heard of that before, but that would in theory work because the components were designed to withstand higher tolerances; that's why the evo will shut off if it gets to roughly 120 degrees [I don't know the exact temperature].

Sorry no.... SoCal.

As another electronics person its a no, if you put it in the oven, it will fry the camera and such and reflow the solder on the board on all the other components as well, possibly causing even more issues other than just frying the components.

Might have found a solution to the USB port fix.
I'm going to make my own surface mount soldering iron. Since regular soldering irons don't fit in the space, this should by all accounts work flawlessly for this problem.
This should be up and running sometime this week and I'll let everyone know how it comes along, and if it works, I might start up a small side business to fix them lol

[Q] Opened phone, now my soft keys don't work

This phone isn't my daily driver and I got a skyrocket on Ebay but it came without volume buttons. Being an idiot, I figured same phone same part....not the case. Long story short, My phone turned back on after putting it back together and my touch screen works but none of my soft keys work and they won't light up. Phone is running stock, non rooted.
the hell did I do? Did I break something or did I just knock a cable loose? Should I be checking for anything specifically?
Thanks in advance.

All the ribbons seem to be plugged in. I think I broke it, but how?!?!?!?!?!??!?!?!?!?! I'm not really worried, i'll just throw it on Ebay; I just don't know what I did wrong. Well, I opened the phone, I know I shouldn't have done that. Any idea on what ribbon cable I should be looking at specifically?

Make sure the ribbon cable isn't torn.
The attached image should help.

Also, Each carrier specific phone will normally have different hardware inside.

it's the Sprint variant.
Edit: I tore the cable, didn't even realize it until you posted that picture. Wow, I really shot myself in the foot here. How difficult is it to replace?

A whole new screen assembly is needed... It is very hard to replace just the soft keys. A heat plate or heat gun is required to separate the glass from the screen to get to them. Much easier to just get a whole new screen/digitizer assembly.

Sell it in separate parts. The mobo and battery will pull the most money. Don't even bother to keep the screen on it. That will lower your total price to maybe $75 at the most. You can easily pull that on just the motherboard alone. the battery can probably be sold for 10 or 15. and the other stuff will vary as well.

[Q] Unglued cable digitizer Samsung Galaxy Note 2

Hello!
I just finish to "unglued" my digitizer cable on my note 2 ,
Please, just take a look at the picture, maybe can I do something to put it back.
Look like unglued..have you any idea if that flex cable it's glued or soldered ?
Thank you very much.

Wow.. I just did the exact same thing yesterday.. same spot on the cable and everything. I did it when I was replacing the glass.. I've tried taping it back.. and now I've tried gluing it , the touch kinda works but really inconsistent and annoying. I've spent way too much time trying to fix it and think I'm just gonna sell as parts now. What did you end up doing? Any luck getting it reattached? If you were successful please let me know what you did.

For me, was no way to put back this flex cable... and I think its close to impossible to make something good with this display.
I just stored that display ....for don't throw it.
Good luck!

this is a usual ribbon cable. i teared mine replacing the screen... will try to replace it and report back.
maybe it will require light smd oven soldering and that will suck big time. maybe i can just pressure it down somehow. your cases are much better, you still have the original cable and half of it is already soldered making it much easier to solder the rest.

thats not the same part, the part u listed on ebay is for the stylus. U can easily tell its not the same part as shown in the original post. Check out this youtube video at the 20:50 minute mark, it will show u the exact parts and u can tell. Youtube: https://www.youtube.com/watch?v=bxgZeb5QytM
Unfortunatly the part the original poster pictured is part of the digitizer and is near impossible to fix once ripped. all ive been able to find online is that ribbon cable being sold with the digitizer itself. If anyone else actually finds the part shown in the original post please do post back.
