Galaxy S4 USB Flex Board cable diferences - General Questions and Answers

Hi,
I ordered today a new USB Board, because my old was damaged an wouldn't charge, neither give sound.
I saw on my favourite online shop from my country that this same cable goes from 7$ up to 35$.
They said that the 7$ cable is original, but I noticed some diferences in the image:

}
I marked in red that I note that there is a piece not soldered on the pins. On the original board, this pin has some black component on it:
Now my question: What are the diferences between them, will one "fry" my board over time or something? And what's about that sensor, I never used the humidity sensor, for what do the s4 use this sensor?
Yet another question:
Some people say that the I9505 USB Board will fit in the I9500 and some say that it doesn't. Who is right?
Because I saw some used ORIGINAL board for like 5$, but they are all for the I9500 and I have the I9505.
I saw that my board has REV.25 on it, and the I9500 board has REV.08 on it, are they any diferences with compatibility?

The i9500 is powered by Samsung's own Exynos processor, while the i9505 has the Snapdragon 600. The USB board might be different because the Snapdragon has certain sensors, modems, and other hardware stuff that the Exynos doesn't. That's just a guess, I don't know for sure. That said, I would go with the board specific to your model just to be safe. Different physical hardware means that they might not be cross-compatible, or even physically fit.

perhaps you can get it at http://shop.ebay.com/i.html?_kw=FEMALE&_kw=htc&_ipg=100
Perfect, Thanks!!!!!!!!!!!!
I was searaching on ebay, how comes i didnt see!
hi dude,
i have this problem for my old artemis, however some things you should know...
firstly, you might find it hard to get the old female extusb off the motherboard, it has a higher grade solder so it has a higher melting point etc and wont come off with a normal soldering iron.
secondly, if you do manage to get it off, the actual pins that conect to the motherboard may be tricky to solder back on, 1 because of the grade of solder, i dont think normal solder will stick ... and 2 because the pins are so tiny.
but, lastly, i actually have one that i do not need, in perfect condition and still in the packaging!
if you have not bought one already, i will be willing to give you it, for free of course!
(because thats how i roll)
if your interested then you will need to contact me via PM dude

30-Pin Dock Connector to Micro USB Data Adapter - CHARGE VIA USB!

Hey guys! Just a heads up on this USB adapter I snagged from USBfever:

IT ALLOWS YOU TO CHARGE VIA USB! It should, of course, be noted that it will probably not charge as fast as it would with the OEM charger or any 2 amp charger. But it does work. It didn't take long to get it (they ship from Hong Kong) and the price is worth it. I have also used it with my Sharper Image portable power pack with success. May have to get myself another one as a backup.
I bought the same one...
Also bought the SD/USB adapter and pickup a original galaxy tab dock for gen 1 model for a fiver down the market,
The dock is a tight fit but I dremeled a slit down the side so it fits much better....
MUST HAVE it too
Sent from my Galaxy Note with DarkyROM 3.3
I have one of those too, but is too tight of a fit for me to dare use it. That's not necessarily representative for other units though, as these chinese accessories don't exactly match up from batch to batch
After some more use I've discovered that while it will let me charge via usb it will not actually recognized that it's connected to a computer. But it was still worth not to carry that big block around with me.

[Q] QI Wireless Charging MOD/Case for Note 10.1

Hello,
is there a possibility for wireless charging for the Note 10.1 out there?
Anybody who put a coil in it?
Or any external solutions?
I could not find anything about it
regards, Christian

I have an idea how you could do it with this very thin $17 kit http://www.ebay.com/itm/Free-Shipping-Wireless-Charge-Power-Module-Board-Charger-Kits-For-DIY-/251314383690?pt=US_Cell_Phone_PDA_Chargers&hash=item3a83812b4a

and this $11 back case cover. http://www.ebay.com/itm/HEAD-CASE-BLACK-X-HARD-CASE-BACK-CASE-COVER-FOR-SAMSUNG-GALAXY-NOTE-10-1-N8000-/190851314616?pt=US_Tablet_eReader_Cases_Covers_Keyboard_Folios&hash=item2c6f9ff3b8
If you sanded off the tabs on this hard cover that hold the Note 10.1 the Note would then just lay in the hard shell and you could get perfect coil alignment without using magnets.
So..... with some odds and ends you most likely already have (tape, soldering iron, hot melt glue, an old usb cable) you could do this for under $30 bucks.
The only 3 issue's I see is will the Note 10.1 charge with only 600 ma of power (not likely), is there enough room to fit the coil under the back cover (good chance) and were do you connect the 5 volt power lead inside the case??????
Here is a disassembly video http://www.youtube.com/watch?v=PUyI74c0DhE that may help if anyone decides to tackle this project because I'm not ready to risking my $400 dollar investment, maybe if I find one with a cracked screen on ebay for cheap I might try it.

[MOTHERBOARD][PHOTOS] myTouch 4G Slide Motherboard

This thread is for all those who want to see what the motherboard of your beloved phone looks like. I had a destroyed myTouch (one of the 5 I've bought, but the 4th doesn't count because it was a Huawei, I got a refund for that) and I've labelled all the important parts. I'm uploading these because of the MSM8260 Snapdragon, also known as Scorpion. The original clock was actually intended for 1.7 GHz but it got too hot so Qualcomm dropped the maximum stock clock to 1242 MHz. Interestingly enough the entire thing is not SoC. The Adreno 220 is separate from the CPU, and the system memory is actually manufactured by Samsung. That is also the case for the Huawei model as well. In the last image the tiny golden box in the way bottom left-hand corner is the microphone. This one is dented. The gold pins sticking up are the antenna connectors, which also houses the speaker on the bottom of the phone. One of them snapped off when I replaced the screen, and that made my network connection not work. The gold metal - is real gold.
Please don't take apart your myTouch to see it yourself. If you want I will add more pictures.

Gear 2 SM-R380 input pin labels

Hello, I have a Gear 2 R380 and have suffered many of the usual and expected problems. The exposed pins on the watch have corroded and failed, the charging cradle failed and refused to stay connected because the clip broke early on and now I have lost the cradle.
I am looking for information that will make it possible for me to make my own charging and communication solution via USB. I have included a picture of the circuit board in a Galaxy Gear charging cradle and if I can get the same for my gear 2 I would be very grateful!

I am NOT interested in buying another charging cradle that will just break AGAIN and frustrate me by not staying connected to the watch while charging.
I'm also NOT interested in buying a replacement contact board to replace the corroded pads on the watch as that will also just be good money down the drain.
I can solder, 3D print, make from scratch everything I'll need once I have the information on the pins. I also enjoy doing this and will are any solution I come up with.
I have tried searching in the the XDA forums and online ave no found the definitive answer I am looking for. There are threads where asked a similar question to mine but the answers are not often not pertaining to the R380 charging cradle, pads on the watch or the associated pads inside the watch.
If you are worried about me damaging my watch, this is a moot point as I cannot use the watch now anyway. I would really like to start using the watch again, without all the usual frustrations.
TIA
Ryan
