[AT&T Samsung Galaxy Note I717] mtucker:
It looks like just shorting D+ to D- on a USB car charger is not always enough to get the note to charge at 1A. It seems like the voltage on D+/D- has to be in the right range also.

I needed more than 500mA charging current in the car for the Note and its big screen (with GPS going also). I knew that I needed to short the D+ and D- pins of the USB charger or cord to let me pull more than 500mA off a 1A+ car charger. I chose to modify the chargers so I could use any standard cable for charging. I did this to two chargers.

1. Belkin Dual USB Car Charger http://www.amazon.com/Belkin-Dual-USB-Car-Charger/dp/B001ILBNGA

2. Griffin PowerJolt Dual Micro Universal Charger http://www.walmart.com/ip/Griffin-P...40656&sourceid=1500000000000003142050&veh=cse

I modified the Belkin first. I used an Ohm meter to confirm I was shorting D+ and D- on the “fast charge” port. Once I put it back together, I confirmed I had 5V across the outer pins and the inner pins were tied together. When I plugged my Note into it using a standard cable, I got a MTP message and the USB symbol appeared in the top left corner. It thought I was connecting to a computer. Removing the cable sent the Note into a media scan.

So I took it apart and double checked. I noticed that the shorted data pins on the high current USB port were about 2.5V and the low current USB port data pins were about 2.0V. I also noticed that the 5V pins for both ports were connected together on the PCB (meaning they are fed off the same 5V regulator). I then shorted the data pins together on the low current port and it worked with that port! The Current Widget showed about 1A and no MTP message. This pointed to the data pins needing a specific voltage (or range of voltage) to make the note charge at 1A (2.5V on the data pins didn't work, but 2V did).

Next I moved onto the Griffin PowerJolt dual charger. This is my favorite car charger as it is very low profile. I did the mod to one of the ports and got the same MTP message (along with only 500mA charging). I noticed the data pins were at 2.5V and that two resistors making up a voltage divider for the data pins were right there. I changed the divider ratio (adding a 50K Ohm resistor in parallel with the resistor that went to ground). I re-measured and saw 1.94V on the data pins (very close to the 2V on the working Belkin port). I plugged her in and sure enough it worked (AC charging and about 1A).

Depending on your charger, it seems as though simply shorting D+ to D- may not be enough to get full current. The data pins have to have the correct voltage on them. Around 2V works although it may be a wide range of voltages (maybe 0V up to 2V?).

Later I went back and modified the high current Belkin port so its data pins were about 2V. That port then worked well too.

This was informative, my phone discharges as well, when I have gps nav on, along with music and bluetooth connected to my car, yes a lot of things, but I want to use only one device for everything anyway, what widget are you using to check the amperage?
[AT&T Samsung Galaxy Note I717] mtucker:
I'm using Current Widget https://play.google.com/store/apps/details?id=com.manor.currentwidget&feature=search_result For Samsung phones, it will display the current *10 until you dig into the menu and use the divide option to tell it to divide by 10.

My GSII would just barely charge with 500mA (screen and GPS on) so I wasn't surprised that the Note can't keep up with 500mA.
[AT&T Samsung Galaxy Note I717] Phoneguy589:
Shorting the green and white wires (towards the phone) bumped my ma's from mid 4k to about 8-9k. I think the voltage state of the battery affects the charging rate as well. Under 70% I'm in the 9K ma range but above 90% I get around 7K ma's.
[AT&T Samsung Galaxy Note I717] bd11goal:
This makes sense as a lithium ion charging circuit should charge quickly to 80 percent and trickle thereafter. Remember that the chargers ability to supply a large amount of current does not mean the phone will consume it; the charging circuit will only draw what it was designed to draw.
[AT&T Samsung Galaxy Note I717] mtucker:
Right. The charging process goes from constant current mode to constant voltage mode (voltage stops near 4.2V and the current drops to keep the voltage the same) somewhere around 80-90% of full charge.
[AT&T Samsung Galaxy Note I717] kimtyson:
Nice discussion here. I followed the Youtube link in the second discussion and created a short USB cable with the short. Works perfectly.
[AT&T Samsung Galaxy Note I717] hyukki:
I bought the Griffin PowerJolt because of its size as well, however, I think mine is a fake one because the internals look very flimsy and cheapy put together.

Anyways, I can't return it since I already modded it...

I somehow managed it to pull .7 amps using a modded data cable (only if I let the spring contact that touches the inside perimeter of the lighter port touch the metal housing of the USB socket, .5 amps if not touching) but that's all I can do. Voltage is the same between the wall stock wall charger vs car charger @ ~4V.

Is there anything else I can do?
[AT&T Samsung Galaxy Note I717] lanwarrior:
Isn't the charger that came with the Samsung official Galaxy Note Car Dock gives out 1A already?

I saw the Car charger output is 1A and the pin should be shorted already, since there is no "sync" capability.
[AT&T Samsung Galaxy Note I717] mtucker:
Some people on Amazon thought they were getting fakes because the Griffin logo looked very light and the packaging was totally generic. Here is a link to a picture someone posted on Amazon showing the insides of the Powerjolt (a authentic version). This is how mine looked too.

[AT&T Samsung Galaxy Note I717] hyukki:
Well, the inductor in mine is very flimsy and does not have the black cover around it. It literally is being held in place by the two leads of the wire coiled around the ring. I'll probably end up ordering a different plug. Or invest 11 dollars for the one that comes with the iPod cable. Although I'm not really complaining with .7 amps, since at least it doesn't let the battery drain as fast.
[AT&T Samsung Galaxy Note I717] NeoH4x0r:
Do you mean 4000 to 9000 ma or 4A - 10A over usb? (this seems a little high for usb most chargers are 500 ma (0.5A) to 2A)

I think it is probably more like 400-1000ma (0.4 to 1A) [which sounds more reasonable for usb]

This is crazy this is my 3rd q &a and no one is helping.......i thought this was a place that you could get help or assistance for the tab.....all i need is to be pointed in the right direction. The problem..... i want to use my flash drive or sd card and charge my tablet at the same time.reason..... I want to watch movies from my tab via hdmi,but we all know the dock must be powered to work thus usb being used.i dont want to load up my tab with movie and music files thats why...fyi. So is it possible or has anyone ever added a usb port to galaxy tab dock.?please and thanx.

Well, if you were this friendly in your first messages I can see why you didn't get an answer. Also, did you create a new account each time you asked?

The answer to your question is "not possible." You cannot connect a charger, USB, and HDMI at the same time. No way, no how.

Ok, First of all, i'm opening this thread, because i've tryied all threads i've found in here, and nothing worked for me. also, all thread appear to be "death"...

A friend of mine came in hurry because que didn't have signal. when i try to check his IMEI i find out that he didn't had any!!

so i've been looking for solutions since then.

the proble is that he didn't make any backup. his efs folder doesn't have any...ANY file named NV_DATA (not even NV_data.bin, nv_data.bin.bak, .nv_data nor .nvdata.bak...or nothing similar).

so, any of the found solutions are capable to help me.

i've tryied making an empty file, but didn't help either..

so..any idea how i could fix this???

[Android Q&A, Help & Troubleshooting] moulaha406:
hi..

i want to know if that it is possible to downgrade any android device without problem ..??

thank you...!!!
[Android Q&A, Help & Troubleshooting] lucaoldb:
I suppose that any android device could be theoretically downgraded to a previous software version. For some devices you can find even s stock Rom, based on an older version of android, so that everything would very likely work... But, if your phone run android 2.3.7 and no stock Rom based on 2.3.3 exists, it won't be easy to find a custom rom based on older software, apart from the need of rooting the phone.

So you would have to build it from source (not easy at all) or trying a port.

In any case, most developers work to get the benefits of the latest software and I think that nobody works to go back to outdated software.
[Android Q&A, Help & Troubleshooting] devwithzachary:
Most of the time you will only be able to downgrade to the first version of android that was shipped with the device (As it can be hard to back port drivers etc) for example my Note was shipped with 2.3.3 so I could not downgrade to anything lower that that
[Android Q&A, Help & Troubleshooting] minikolli:
Yes, I believe it's possible to downgrade your device. You just have to flash some special ROM (with older Android version).
[Android Q&A, Help & Troubleshooting] charlieboy999:
Hello all,

This is my first post for a new thread. Hopefully, I'll be clear enough for this to make sense.

I recently got a rooted Zopo ZP-200 (basically a decent Chinese clone of the HTC Evo with Dual Sims) on Android 2.3.

I realised that some sensors aren't working- the gyroscope and magnetometer. It seems that they effectively lie dormant in the phone. For example, compass doesn't work. And any motion-based applications do not working.

In fact, I can't find anywhere to calibrate them and when I run hardware tests, I get no results. However, they do show the hardware is there!

Gyro:

Name: Invensensor MPU3000 gyroscope Sensor (4,1)

Power: 6.100mA

Max Range: 34.910rad/s

Resolution: 0.011rad/s

Raw Data:

X=???

Y=???

Z=???

Magnetometer:

Name: Alchi Steel AMI304 3-axis Magnetic Field Sensor (2,1)

Power: 0.250mA

Max Range: 600.000uT

Resolution: 0.002uT

Raw Data:

X=???

Y=???

Z=???

Does anyone have any knowledge about this sort of thing? I admit, that I'm stumped. Perhaps if there were a way in which I could activate them or implement some sort of way to configure them?

Are there better diagnostics I can do? I'm normally just an end-user, so please try not to get too technical!

Many thanks!

[Transformer TF300T Q&A, Help & Troubleshooting] dsf3g:
I've got a sneaking supicion that the textured ridges on the back of the tablet might trap dirt and make the white model look pretty ratty after a while.

[Transformer TF300T Q&A, Help & Troubleshooting] MrTonyToca:
very true! I wonder why they like to flaunt different colors and then never release them to the US!? SMH
[Transformer TF300T Q&A, Help & Troubleshooting] ryzilla23:
Red and blue would be the best bets. The white fades and scuffs easily. I imagine the ridges would show a lot of dust/dirt as well.

Bestbuy isn't great at carrying alternate colors unless its something exclusive to them. I doubt they will have them. The time table last i heard for them to come out was in late June.

There hasn't been any dates announced by Asus. Since the release of the blue TF300, June has been the expected time frame for the release of the red and white versions, but nothing is certain on that. As for the TF700, summer or early fall are the main rumors I've heard, but again, no exact dates.

I really like it!! the screen is pretty crazy. I can look at it from any angle and it looks crystal clear sharp like the fake photo's they put on phones in stores that aren't powered on.

I give build quality a B, but compare it to other phones its def an A+. A step in the right direction and i hope phone manufacturers continue in the trend, phones just feel terrible nowadays, all plastic ETC. They just dont last the abuse they are put through.

kickstand is beyond sturdy. OG Evo wasn't 100% stable and this one (probably because of placement) is amazingly stable, even when its in portrait facing you.

one quirk i've noticed so far; is that the dedicated camera button doesn't actually open the camera app. But it probably just needs to be set somewhere, but that brings up a point.. you could set it to anything you wanted....

edit: aha! just gotta hold the button for a second (it vibrates to let you know it registered) and then let go, and then it opens. pretty nice for the accidental bump!
