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

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

I had my rooted Nook Simple Touch froze on me.
Series of events:
1) I thought it needed to be charged
-So I charged it
-Still Frozen but would restart when I plugged it back in
2) I thought the root had cause something so I reformatted it using: http://forum.xda-developers.com/showthread.php?t=1289233
-Still Frozen when unplugged and restart on being replugged in
3) Reformatted again for good measure then rooted using: http://forum.xda-developers.com/showthread.php?t=1343143
-Still frozen
4) Called B&N tech Support: No help, cycle nook, turn off, cycle nook, turn off, no change, said to let it power down to 20% and that you should only charge for 3-4 hours and that you can over charge the unit??????, thanks anyways.
5) Used Ifixit.com teardown to see if there was something going on inside: http://www.ifixit.com/Teardown/Nook+Simple+Touch+with+GlowLight+Teardown/9301/1
-Took off back, upplugged battery
-Found nothing loose or broken inside
-Found a port for a cell antenna, interesting
-Unplugged the screen from the motherboard
-Put it back together
-TADA!! it works again. I think that hard resetting the battery did the trick but also voided any warranty I had. (which was none since it is over 1 year old.
I searched for a resolution to this problem everywhere and could not find one so I am putting one here. Thank you for your time.

Sorry you didn't see this, and I'm glad to see the fix being bumped - this was the thread with the fix before you needed to do the work -- but congrats on a successful self-repair and clear documentation.

PiPo M9 drop dead =<

Hey!
I had a PiPo M9 (WiFi) now for about 2-3 weeks and everything worked perfectly.
No problems with rooting and installing ROMS ( i fixed that 2-3 days after i bought it)
I was playing some angry birds yesterday, and all of sudden i had VERY low battery, i put it on charge even if i recently took it from it.
Then i noticed that the DC-connection in my tablet is "loose" , i needed to have the cable in a specific position for make it charge.
Battery was fully charged but it said i had about 16 minutes left, and in 1 minute it dropped to 43% and only had 2 minutes of the battery left...
I tried to calibrate the battery after it was fully charged (i let it charge for almost 10 hours) but there was no difference...
Anyways... i played some games later on and forgot about the position of the cable so the tablet died...It had a bootloop about 6 times and i was trying to put the cable correct for make it charge but i failed and the tablet died.
Now it doesnt react at all, and unfortunally i don't know what the EXACTLY position is for the cable so i have been trying around but without success...
When i am connecting the USB to the computer it doens't react either, and i tried to push in RESET while holding the other buttoms as well, without success...
I Don't know what to do , and i don't know what is wrong?
I opened up my tablet carefully to see if i could see the problem but it is hard to do anything without knowledge about it....
I know that it has something to do with the DC-connection but i can also imagine that it has something to do with the batteries..
If i need to change the batteries , what should i buy? And how should i do? I need a guide, walkthrough ,... i have been googling around , also on youtube, without any luck...
Anyone out there who can help me?
I am kinda desperate.. :/

I solded and fixed the DC-contact, it was loose, but there is a component missing and i am unsure what component it is, so i have a picture and hope someone can help me out....
I'm a little unsure of what component that is missing, but it is backside off the mainboard, just below the dc connection.

Should I try to save my black screen nexus 4?

Hello people.
I need help to decide if I should try to save my nexus 4 or not. It has been dismantled for the past half a year and i recently got it to show signs of life after battling the steady red ring of death. (Was simple by the way, just used a wireless charger for a couple of minutes) But if I turn it on, it vibrates, the screen lights up and that is just about it. So i have no idea if the phone itself is functional. Some of you might tell me not to bother with such an old phone, hell, they aren't even sold anymore. But this phone has stuck by me through thick and thin, and has a sentimental value. I nearly jumped of joy when it showed signs of life after such a long time. I am not a rich man, so i need to manage my finances. Screen replacement would cost me 25 pounds, back housing would be another 10, but what if the phone is still not functional? Is there any way I can find out if I should take the gamble?
Some info -
I am not entirely sure if there is an OS currently installed on the device, as I was experimenting quite a bit before the battery run its coure.
I am also missing one of the connector things that are circled (there is one and a broken spot where another one should be) but i have no idea what it connects to. The little peg itself is safe and sound in my possession, if it can be welded back. It connects to whatever is under the power button on the back housing.

The screen is cracked in three places, but was working the last time I remember. But there have been many (and I mean many) dis and re assemblies since then.
I probably love this phone more than my friends and family. Just want my favourite piece of tech to be my companion again.

Could the red light be due to a dead battery?

Thankls for the reply. The battery is new and the red light issue is sorted. The phone just doesnt do much more other than vibrate and light up the screen. How do i know if it is still worth investing money in is the real question.

Nexus 6p had an unexpected short swim in the sea... trying to revive it :(

Hi all!
I'm writing here with deep hope that someone can help me somehow...
I got my 6p popped in the sea a month ago just as far s the camera glass goes. I've turned it off immediately, but because I was in a small place, didn't manage to find some phone shop or any way to open it and dismantle the battery. I did try to turned it on (stupid me) later on that day and after that left if for 2 days to dry.
My hopes rose when it did give some kind of a "life signal" when on charger but that's as far as I got...
So, when I put it on charger I get the Battery animation icon with 50% showing on the bottom, after few secs it shows 0%. Also, while on charger it just bootloops... can't get pass the Android boot animation, it just restarts. However, I can get to recovery (TWRP) and browse through it (make backups etc) while on charger it doesn't restart. The thing is that it only works with wall charger, I can't get to recovery when connected to computer via USB (so I can't even get that backup or transfer files from the phone ).
I've went to two phone repair shops in my town, but both said that it's dead. The thing is I'm not sure that they even tried with new battery, because this is a rare phone in my country and they probably don't even have one to try...
Anyway, I've ordered new battery, but I'm afraid if that'll help... I would like, at least to connect it somehow to my computer and try to transfer files and maybe do some factory resting or loading an image...
I have some pics from one of the repair shops, so I hope someone could help me determine if there is any help with it?
Thanks in advance!!!
Cheers,
Djape
