Solder should look like 2nd one counting from right, about 1/2 shorter and bit flatter.

Now it is time to reseat pins height since they will need to stick to new solder point. I marked for you those pins and all you need to do is raise them a little bit, not too much or they will break apart, just do it gently.

THE END
If you did it properly your GPS fix should be much faster and more accurate than ever.

Removing the camera unit from SGS, please help!

Hi,
I'm thinking of removing the Camera unit from my phone as camera mobiles are not allowed in my office.
http://www.ifixit.com/Teardown/Samsung-Galaxy-S-4G-Teardown/4977/1
http://www.ifixit.com/Teardown/Samsung-Galaxy-S-I-9000-Teardown/7122/1
http://www.ebay.in/itm/Opening-tool...4?pt=LH_DefaultDomain_203&hash=item416585c42c
Based on this, I'm confident that I can remove the camera from the mobile. But after removing the entire chip, will the phone have any trouble in booting?
I mean, while the phone is booting, will it be looking for camera unit and will fail in booting if there aren't any camera units found? I know this doesn't make any sense, but still I don't want to take any chance....
XDAians please shed some light on this topic! Also if you have any tips on removing camera, please share your information.
Thanks
Removing the camera is very easy if you know how to take the phone apart (don't break the tabs on the chrome trim).
And the phone will boot just fine.
This is my first time removing the panel. Hope it is as easy as you say.
And I'll look out for that tabs on the chrome trim.
i have changed the Mainboard a few weeks ago.
The hardest work was to split the cover.
Here the guy use a tool

i suggest to use your fingernails.
Second, there is a small white cable between mainboard and the board in the bottom.
Don't crush it, when you reassemble the phone.

[Hardware Mod] Hyunday A7HD weak wifi fix

Warning: this mod requires special skills in opening the device, and soldering, please do not do it unless you know how to do it, I'm not responsible for any damage that may happen to your self or your device, this mod will void your warranty.
I've been searching the internet for the last month, searching for a solution for the poor WIFI performance of the A7HD (and many other Allwinner A10 tablets)
I've tried many different antenna designs such as:
http://fabiobaltieri.com/2012/06/02/diy-cheap-internal-wifi-antenna/
and this (without the reflector)
http://img.engadget.com/common/images/3060000000054059.JPG
i also did the original antenna mod
this:

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
but with all of these mods, the WIFI performance is still weak, untill i found this video on you tube:
http://www.youtube.com/watch?v=nli8nO8PNzM
this guy have gone the extra mile, and as he explained, the manufacturers had put two resistors between the antenna (positive) lead, and the ground
all i did was removing one resistor
now with the original antenna (with the original antenna mod) , i have wayyyy better WIFI, faster, and more stable, before in my next room where the router is, i was getting 1 bar of WIFI signal, now i have 3 bars, and some time 4 bars .
i didn't remove the second resistor (just as the video) but i think removing it will make it slightly better (if any one could do it and report back the results).

what to do when your phone gets wet

What to do when your
phone gets wet?
Try this tips when the mobile get
wet-
1.First thing remove the battery
as
soon as possible from mobile.
[Cause the power gets stopped
and
thus does not affect the circuit
and
board inside the mobile]
2.Dont forget to remove your sim
from the mobile unit.
[contains useful numbers]
3.Remove the panel and make the
phone to dry for 2-3 hours .
[ Use a paper as it helps to dry
quicker]
4. Place your mobile in bowl
containing rice [uncooked] 16-18
hrs.
[As this helps to dry out]
5.place your mobile in a plastic
pouch with silica
[comes with almost all electronic
goods, as it sucks the water]
Note-Don't use any sort of hair
dryers / hot objects as these may
lead to damage in the board/
battery
may explode.
Try to reach your mobile service
provide if warranty includes any
water damage then u get a
replacement.
Hope the above things works for
you.

[Q] LG G2 - cannot make/received call after a short fall in the water. any advice?

hi everyone,
after almost 18 month of enjoyment it appends : i fall with my phone in the water!
i dried it the best as i can. I even opened it (see picture 1). Unfortunately now it's just half working because it cannot make or receive any call.
Looking carefully to the inside of the phone, i notice a part of the chip is altered (see the Red circle in picture 2)
=> Do you think is the right reason for this problem ?
=> Do you know if it can be fixed and how ?
I also notice that
- the batteries are drain in 7 hours (15 before)
- the phone is hot (temperature)
- the phone reboot by itself
I think those 3 symptoms are a consequence of the cellular services running for nothing (see picture 3)
=> Do you think I'm Right ?
=> Do you know how to dis-activate the cellular services ?
Thank you for reading my post and helping me if you can

Something has obviously been fried. Probably need motherboard replacement that wont be more cheaper than getting a new second hand G2

[Q] Can you identify this part?

Opened up an old PC on a stick to see what I could do to improve wireless signal and ended up breaking off what appears to be a part of the wifi antenna however I have no idea what it is correctly called, a few google searches and I come up short. I want to know what the part is called so that hopefully I can find out how to reattach it.
The part looks like a gold color pin that pushes in, sort of like a micro plunger. When the case is put back together there is a metal plate on the case that makes contact with this pin to create an antenna of sorts.
I would just solder it back on but I can't make out any metal contact left to solder to on the spot where it broke off from.

Howdy mate,
That's a surface mount pogo pin, Lson is a company that makes them, you could probably salvage one if you could find an old car kit or phone charger from the late 90's. You could also replace it with a piece of springy steel from a battery terminal but that might affect the antenna wavelength.
Tetsuo
Thank you!
That is exactly correct
