[Tilt, TyTN II, MDA Vario III General] erik29gamer:
My Tilt was low on battery so I went to plug it into my computer. Turns out my brother took my USB cable, so I went to my room and found a USB power plug for an old iHome.(Only after plugging it in did I realize it wasn't standard USB voltage, it was 9v) Well I plugged it in, and my phone immediately turned off, and now it constantly reboots to the Smart Mobility boot screen, vibrates, and restarts again. I left it with the battery/microSD card/ SIM card out for 24 hours, but still nothing. I've tried Hard Resetting, and re-flashing through the microSD card, but nothing seems to work. Any ideas?
[Tilt, TyTN II, MDA Vario III General] Mr. Clown:
Have try another battery?, probably your battery was the one that really got smashed with those 9v.:D
[Tilt, TyTN II, MDA Vario III General] erik29gamer:
I don't think its the battery, because it still holds a charge, and can boot into the boot loader and hard reset screen fine. Is it possible that the battery just can't provide enough power for the full OS? Is there anyway to boot off of USB alone? I don't have another battery (currently) so I can't really test that.
[Tilt, TyTN II, MDA Vario III General] Mr. Clown:
Try to reflash, since you can get in bootloader and see if that solves the problem.
[Tilt, TyTN II, MDA Vario III General] denco7:
Same thing happened to me, it had enough power to get and remain in bootloader but not enough to boot OS. Put in a new battery and has run perfect ever since. 3 mon.
[Tilt, TyTN II, MDA Vario III General] tommytepntn:
Agree with mate
[Tilt, TyTN II, MDA Vario III General] erik29gamer:
Sorry for reviving my own post, but i finally got a replacement battery and it still just vibrates, smart mobility screen, then repeats. I just tried flashing it with the stock att rom and the only difference is att screen instead of smart mobility. Any other suggestions?

EDIT: Also tried flashing android but does the same thing, vibrates, flashes boot screen, repeats :(
[Nexus One General] breezyxhype:
Which ones can be installed exactly. I want to at least get the music app. Anyone know how? Kinda new to this.
[Nexus One General] esincho:
U gone get roasted 4 posting this without searching. LOL. U can't use HTC apps or wigets without using a Desire ROM. It's been asked 100 times already
[Nexus One General] finisterre:
Well, you can use the odd thing. I have Teeter and the HTC IME keyboard rom the Desire ROM on my Nexus One. I'm sure there'll be a couple of other things too.

From what i understand most of the apps/widgets rely on the desire's framework, and since the nexus one's is different they will not work.

Learn to search. This thread should be locked now

Install the desire rom, use launcher2.apk and enjoy all worlds.

Most desire apps depend on the rosie framework so yanking them out won't work...

Hey guys,

Have you ever had problem logging on a SSL certificate network?? An example is the cisco authentication on the wifi ( like my college has ). Well looking around I found this solution posted by dalvik.

[Nexus One Accessories] dnts:
It seems the only way to fast charge a N1 is with the supplied wall charger. Standard Micro USB chargers whould only allow at much as 450mA of charge current regardless of the adapter current capacity.

The bundled charger however, manages to push 900mA into the N1. I made a cut in the charger wires and measured the current draw to make sure.

Now.. I'd like my car charger to be able to do the same. There must be some hack in the plug of the N1 charger since there are only 2 conductors from the case to the plug. You can see that the plug is somewhat longer than similar Micro USB plugs..

So I tried to see if one of the 3 unused pins can tell me anything but.. they seem unconnected as far as I could tell. Diode measurement (to test for any digital part inside) also did not produce any results. The next obvious step is to take the molded plug apart but I'd rather not...

Does anyone have any clue as to what makes that plug so special?

And please - I did my tests with a bench power supply - not the car chargers - so don't go around telling me it has to do with charger current capacity.

Thanks,

Nir
[Nexus One Accessories] followinginsanity:
are you sure the micro usb cords you are using are able to handle the amps? most chargers made prior to now, only push about 450mA, the G1, and N1 chargers i have push a full amp though. I just ordered a car charger that pushes an amp too. There is nothing "special" about the plug.
[Nexus One Accessories] dnts:
I beg to differ. All the cords can easily supply 1 AMP. It is the phone itself that decides how much to draw from the charger based on something IN THE PLUG.

I am an electronics engineer so do understand I know perfectly what I am talking about :-)

And your 1A car charger does not supply anything over 0.45A to the phone.. you will see that if you are using the phone while it charges (say nav or phone call) the phone actually looses some charge albeit it being charged... This will not happen with the stock wall charger.
[Nexus One Accessories] SBS_:
I have a 900mAh car charger that I use and it does in fact give 900mAh to the phone while charging. I can tell because I used a 450mAh charger at home before and it was slooow and I could drain my phone while charging it. With the car charger I can stream music with spotify, use the GPS, have the screen on full brightness and the battery % will still go up.

I also bought a new wall charger recently, which is 850mAh on the USB port and has a 350mAh charger for a loose battery as well, works quite nice.
[Nexus One Accessories] scote:
Has anyone measured the voltage or put a scope on the output of the stock charger?

maybe stock charger has a slight variance in voltage over USB chargers or some signalling going on and this tells the N1 to take more current from it?

I would like a solution to this too I've seen my phone discharge while on a supposedly 1A car charger using co-pilot.
[Nexus One Accessories] dnts:
Forget the numbers on the chargers - what counts is what really goes into the phone and that needs to be measured with a current meter (test equipment). What you may think to be fast might not be that.

Original HTC chargers obviously do the trick of fast charging but this comes at a price compared to the $3-$4 garden variety on Ebay and the likes.
[Nexus One Accessories] GazzaK:
now I cannot help you with the electronics at all, but, my old HTC Touch Pro charger seems to charge the same as the one which came with the phone, is this correct?

(suits me if it is, as then I have a charger for home and work)

my blackberry bold 2 charger only says it outputs 700MAh, but both the google and htc chargers both say 1.0A
[Nexus One Accessories] SBS_:
Yes, it is just anecdotal evidence as I don't have any equipment to measure it. But my phone no longer discharges when I use it while charging, which it used to do with the old charger I used. So while I can say for a fact that the charger I use now is faster, I can't say by how much (this goes for both the car charger and the one I put in the wall socket).
[Nexus One Accessories] SurfHost:
I ordered this charger a few weeks ago and it charges my phone as fast as the original charger. The label says 5v / 1200mA.

Genuine Nokia Mini AC-10U US Type AC Charger (100~240V)

$7,25 and free shipping. (Takes a while before you get it tho.)

HTC Touch Pro = mini USB

Nexus One = micro USB
[Nexus One Accessories] tedSmith123:
Not an engineering here, but I am guessing the phone not always drawing more than 500ma may be is to do with the charger itself.

There is this "fast charge" USB standard where a wall plug has the USB data pins shorted to indicate that it is a wall plug and hence the phone knows when to draw more power. So even if the charger is rated 1A, the phone might not know if it could utilize that if those pins aren't shorted. Try doing a quick Google on this ....

If someone can test if the stock charger that came with the phone in fact does have those pins shorted that would confirm part of this theory.
[Nexus One Accessories] dnts:
For all practical purpose - I used two cables/plugs with a bench adjustable power supply. Simple micro USB plug would only let me draw 450mA regardless of power supply voltage in the range 4.5-5.5V. Tried shorting data pins - nothing. Tried shorting spare pin to VCC or GND or any of the other pins - nothing.

Used original cable and plug - draws 900mA at voltages from 4.9-5.5.

So it's in the plug somehow.

Tried (very difficult) to see if the pins on the plug are shorted and all 3 spares (except for 5V and GND) seems unconnected.

Next step is the irreversible hot knife...
[Nexus One Accessories] StefanSarzio:
I'm bugged by this, too. I tested with my desktop dock connected to my car charger (which states 1000 mA): it loads slowly and my battery widget reports USB- instead of AC-charger.

Might it be that the phone tries to load more than 1000 mA at the beginning to be sure that it doesn't overload the charger? And if that fails, it falls back to 500 mA?
[Nexus One Accessories] rashid11:
Could N1 use a simple logic of:

- always watch the voltage

- start drawing 500ma (or whichever is the lowest current as per USB spec)

- increment in say 50ma steps

- if voltage drops below 4.x V, back off and stay at that level
[Nexus One Accessories] garfnodie:
I just did a little test of my own. I have a Palm Pre car charger (actual Palm brand one labeled as 1000ma output) and I plunged my N1 into it on my way home from work. In twenty eight minutes, my battery went from 47% to 70%. Much faster than plugging into my computer, which is 500ma max. I don't have any fancy test equipment, and don't claim to know a whole lot about electronics, but seems pretty fast to me.
[Nexus One Accessories] big_adventure:
I have a 4-port 2A 5v USB charger, and connecting it to my Nexus OR Milestone with a MicroUSB cable (the one that shipped with either phone, or the one from my Kindle) yields painfully slow charging - it basically won't charge if you are using the phone.

Connecting the Nexus One charger yields fast charging on either phone - so it is not HTC (or Motorola) proprietary.

The Milestone comes with a 900mA USB plug, and connecting THAT to either phone with either of the MicroUSB cables yields fast charging.

I have another aftermarket 2 port 2A 5V USB wall charger (brand: T'nB) AND I have an iPhone USB plug, and both give fast charging on the Milestone, and I have not yet tried them on the Nexus One.

Breakdown (on things I've tried):

FAST CHARGING on Nexus One AND Milestone:

Nexus charger (either in the US (110v/60hz) or in France (220v/50hz) through an adaptor)

Milestone wall French USB plug (which I think is something odd like 850mA at 5.9v) with ANY microUSB cable (in fact, it seems to charge both of the phones faster than the stock Nexus One plug)

SLOW CHARGING on Nexus One AND Milestone:

USB plug on computer

One aftermarket 4 port 2A 5V USB charger (NOT a hub, only a charger)

FAST CHARGING on Milestone, untested with Nexus One

T'nB 2 port 5v 2A USB wall charger

Apple iPhone 1 port 1A 5v USB wall adaptor
[Nexus One Accessories] chankc28:
Seems found the answer for Fast Charging N1

I had just do some test for Charging N1 With Original AC Charger , Other band USB Charger and PC USB charger.

1. Orginal Charger give N1 from 0% to 100% at about 2 hour and something.

2. The other band AC charger and PC USB Charger can only finish the same job over 5 to 6 hours.

The Fast Charging is Due to 5.1V (Measured at N1) and 5.2V(Measured inside AC charger). 0.1V Drop is due to resistance of USB cable.

The Slow charged is due to 4.8V (measured at N1) and 5.0V (measured on PC USB and Other AC Charger)

i.e. Original Charger mod from 5.0 V to 5.2V (about 10% increase in Voltage)

:):)
[Nexus One Accessories] rashid11:
Looks my theory is correct then ? N1 watches the voltage and if it droops too much, it backs off the current.

So the key would be: get a charger than can maintain at least 1A @ 5.2V, use

a decent gauge, short wire from the brick to N1.
[Nexus One Accessories] ConstantineXVI:
Has anyone tried a Blackberry charger on the N1? Will they work to full capacity as well? (They're on Amazon for a fiver)

Because the nokia charger is working

http://pinoutsguide.com/CellularPhones-Nokia/micro_usb_connector_pinout.shtml

see info under table.

I tested also HP charger + standard USB cable delivered with Nexus, and it is charching cca 1A.

Then I tested one noname Carcharger + standard USB cable delivered with Nexus, and also charging cca 1A.

I dismantle the noname carcharger and here is a result:

data line (pin2+3) is shorted and connected do + (pin1 ,Vcc) thrue resistor cca 630kOhm.

1 - 4 = 5.1V

2,3 - 4 = 3.2V

I try to use power supply 5.2V 2A with cable without dataline (pin 2and3 not connected) and it is charging 480mA only. :(
[Nexus One Accessories] StefanSarzio:
I have now tested with an HTC car charger for the HD2. It's fast charging (tested with Waze running, two bluetooth connections and playing mp3 - and it's still loading the battery, whereas before it would be stuck at the current percentage) and even shows AC power instead of USB.
[Nexus One Accessories] cybrian:
For whatever reason, iPods won't charge via USB unless data+ and Vcc are connected together via a resistor (I forget what value), so that's probably why those are connected like that. My experiment (which I detailed extensively below) proves that your discovery of your noname USB charger is what we needed to know.

Also, before I get into that, you can easily tell if it's in fast charging mode or not by going to Phone, dialing *#*#4636#*#* and touching "Battery Info." Under "Power plug" it'll say "USB" in slow charging mode and "AC" in fast charging mode.

That said, I shorted D+ and D- together and soldered a 470 kΩ resistor (closest I could find to 630 kΩ) to them connected an ammeter between it and Vcc on a USB female plug, connected it to a 5 volt power supply with a built in ammeter (and current limiter), and plugged my Nexus One in. It went into fast charging mode, and the power supply's ammeter said it was drawing about 600-800 mA (it kept fluctuating around, though). My ammeter on the data pins said that it's not drawing any current at all from the power there, however. Then, I disconnected the data pins from the meter and power supply so they were no longer connected to anything, and astonishingly it remained in fast charging mode.

I then soldered a USB male connector and a USB female connector together with the pins like this: Male Vcc - Female Vcc and one side of a 470 kΩ resistor, Male Ground - Female Ground, Male D+ cut, Male D- cut, and then soldered the female D+ and D- together and to the other side of the resistor. I plugged it into a USB charger, and it went into fast charging mode.

Just as a warning if you make a cable like mine: don't plug it into your computer. You may get an overcurrent notice and have your USB ports disabled until a reboot, because until a recent addition to the USB specification (known as "Battery Charging Specification) not only are your computer's USB ports usually designed not to supply more than 500 mA, but also, according to the USB specification a USB device is not supposed to draw more than 100 mA before requesting to be a "high power" device (drawing up to 500 mA or up to 1500 mA if it supports Battery Charging) so it'll be drawing a maximum of ten times what it's supposed to.

Apple computers (specifically their notebooks) definitely support Battery Charging Specification, though, and in fact I have my Nexus One attached to my MacBook Pro via that adapter, fast charging over USB right now. It fully charged real fast (so it's definitely working) and the MacBook Pro never complained.

I'm going to be buying some male USB connectors so I can build a few of these adapters for my parents' cars.
[Nexus One Accessories] big_adventure:
Excellent work!
[Nexus One Accessories] cybrian:
Thanks! But I wouldn't have figured anything out without the lead mijou gave us.
[Nexus One Accessories] cybrian:
Hm, interestingly enough, my USB charger adapter cable I made also will charge an iPod touch. Just applying 5 volts across Vcc and Ground normally doesn't charge an iPod, but this adapter makes it charge.
[Nexus One Accessories] pokey9000:
I took a look at the USB Battery Charging spec to see if the N1 obeys the new standard. According to the spec, a dedicated charging port (AKA wall charger, car charger, etc) signals that it is capable of providing from 500mA to 1.5A by connecting D+ to D- through a maximum of 200 ohms. This means that if you short D+ to D- and connect them to nothing else then the N1 should charge at full tilt.

I tried this, using a 10 ohm resistor between D+ and D- for paranoia's sake and got my N1 to fast charge. That is, 5V to red, ground to black, 10 ohm resistor between green and white.

It should work if you short D+ and D- together without a resistor according to the spec, which is what I suspect some of you above have done with the 470k resistor as a red herring.
[Nexus One Accessories] hgmichna:
Confirm - shorting data lines works

Here is a much belated reply. I just shorted the data lines, and it now works in the car. The Nexus One now shows "Charging (AC)", where it used to show "Charging (USB)" before.

I'm using a cigarette lighter socket adapter with two USB sockets and now the modified cable.

How did I do it? I took a sharp knife and cut out the soft, black plastic on the side where the micro USB plug is a bit narrower. I found that I had to cut more on the plug side than on the cable side.

Luckily on that side I found the two data wires, soldered to the plug. When I hold the plug cable down, these two contacts are slightly left of center, which confirms that the are indeed the contacts number 2 and 3.

I took a small soldering iron and put a tiny drop of solder on the two soldered contacts, melting the contacts and shorting them.

Then I switched on the electricity in the car, plugged in my oldest, cheapest cigarette-lighter-to-USB adapter, stared at its light, and very slowly plugged in the USB cable, fearing a spark, some smoke, and perhaps a blown fuse, but nothing of that sort happened.

Next I plugged in the Nexus One and selected Menu, Settings, About phone, Status, and it said "Battery status - Charging (AC). Hooray!

I'm going to Africa on Sunday and really needed this very badly, because the map and navigation used to draw more power from the phone's battery than the phone took from the car adapter, so the thing ran empty in spite of being charged. Now I have a chance (provided the phone survives the heat, dust, and the vibrations of extended driving on rough roads).

Can you please tell me where to go about obtaining it?

I have a no-name car charger which supposedly outputs 2A but my N1 actually drains out if I'm using that car charger and utilizing GPS, music etc.

Thanks
[Nexus One Accessories] Kage_:
I bought the 2A iPad charger from Griffin and then got a 3' microUSB cable w/ 26awg wire. I modified the cable and shorted D+ and D- together. My N1 charges like it was using the wall plug in my truck. I've had this setup for about 6 months and it works great. :)
[Nexus One Accessories] mecha2012:
a dedicated charger these days as im writing have a pcb board inside the micro usb connector itself with the 200< ohm resistor on it tieing the data lines together. I found this out when i was trying to modify my usb cable to about 5 meters so i can sit on the couch watch tv charge my phone and be on my phone lol.
[Nexus One Accessories] hgmichna:
Back from Africa and all is well. I had the Nexus One in a phone holder that grips into an air vent on the dashboard, some foam rubber stuffed underneath, so the angle was good and the phone was hinged super-softly, and the cool air fan on when it was warm.

The phone survived without a hitch and navigated most of the time.

A big surprise for me was that the charger, a mumbi Mini KFZ USB Adapter DUAL - 2 USB Ports Duo, which I bought through Amazon, stayed absolutely cool, contrary to another similar adapter I had tried before. Apparently it uses some really good switching electronics.

For charging I used the self-modified USB cable with the two data lines shorted.

All car chargers I have tried influence the car radio and made the reception of a weak station more difficult or impossible. Perhaps a USB cable with magnetic filters on both sides might work better, but I didn't have one of those. It is unclear whether the cause is actually the charger, but when I pull the charger out of the cigarette lighter socket, leaving all other connections in place, the interference ceases. This still does not prove that the charger is the cause, but it seems likely.

The biggest problem was the extremely poor software, particularly Google's, that could not cope with the more difficult real-world conditions in Africa. As long as the software worked, it worked very nicely, but then I saw multiple crashes (Google Maps), the total destruction of large amounts of user data (Google My Tracks), and software that was partly impossible to use due to a very poor user interface (Locus). But that's another story altogether.
