Picked it up last night. I don't care how long it takes, it's worth it just for the external charger, even if the batteries suck.

Worst case scenario, it would still get me a few extra hours. Best case: 4 batteries. Good deal.
[Thunderbolt Accessories] contractcooker:
Seems way too cheap to me but I just pulled the trigger too. Hopefully at least the charger works.
[Thunderbolt Accessories] Mad Llama:
Their website is htcexpress.com. I got the 1800 mah batteries for my DInc. One of them gets way better than stock life and the other about the same. So hit or miss, I guess. I ordered some 1500s for my Bolt. Looks like it uses the same batteries as the MyTouch 4G.
[Thunderbolt Accessories] tmushy:
You guys know thats an aftermarket battery in the amazon listing

deceiving pictures
[Thunderbolt Accessories] jfugate15:
I have purchased the "replacement" aftermarket batteries from overseas for the third time now. The first was for the Touch Pro, next for the Touch Pro 2 and now for the Thunderbolt. They arent as good as the OEM IMHO but do they really need to be?? I suggest being very careful with the wall charger though, very easy to brake stuff on the inside of the thing. After that happens it takes time (plugging and unplugging the stupid thing in the wall) to get it to charge a battery. Overall for the price u cant beat it!
[Thunderbolt Accessories] ryanstfl:
http://www.amazon.com/gp/product/B004GSWOZQ from what I've read the MyTouch has the same battery, I've purchased it and I'll give an update when I receive it. It's only 24.99 versus the 34.99 that they're marketing for the Thunderbolt.

How would I go about using 2 sd cards with different roms on them on the same EVO?

Would things get messy?
[EVO 4G Q&A, Help & Troubleshooting] bkrodgers:
I don't follow. We don't run ROMs from our SD cards on the Evo. Switching SD cards doesn't switch ROMs.
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
You flash a rom from the sdcard, its not run from the sdcard. If you switch sdcards, you'll still be on the rom you'll still be on the rom you loaded.
[EVO 4G Q&A, Help & Troubleshooting] cruise350:
Do a nandroid backup of the rom you want to use with each sdcard and then when you switch sdcards just do a nandroid restore from that sdcard. I do this when I switch between my favorite sense rom Sprint Lovers and my favorite CM7 GB rom destroyer. This way my sd cards are set up for the programs I use with the different roms and the apps that are on the sd card or in system memory won't get messed up when I switch between roms. I just swap out sd cards and then upon reboot, enter recovery and nandroid restore. Then everything is where it should be and I don't have to install anything.
[Nook Color Accessories] adsbar:
I haven't seen a thread that addresses this specifically:

After reading the threads in this section, it seems that the consensus is that the "fast charging" aspect of the NC is based on extra pins in the special NC cable. When connected to any charger with 1.9amps or greater, you will get the fast charge.

My experience is different.

Using the OEM NC cable:

1. Connected to OEM charger, stock ROM - settings say charging, flashes an icon with charging percent on connection and removal

2. Connected to OEM charger, CM7 - settings say Charging (AC).

3. Connected to 2.1 and 2.0 amp chargers, stock - settings say Not Charging.

4. Connected to 2.1 and 2.0 amp chargers, CM7 - settings say Charging (USB)

Using the generic microusb cables (2 or 3 tried):

1. Connected to OEM charger, stock ROM - Can't remember, but not going back to stock!

2. Connected to OEM charger, CM7 - settings say Charging (AC).

3. Connected to 2.1 and 2.0 amp chargers, stock - settings say Not Charging.

4. Connected to 2.1 and 2.0 amp chargers, CM7 - settings say Charging (USB)

This seems to imply that the OEM charger is required to really use the extra pins in the NC OEM cable. Can anyone test and confirm this?

[Nook Color Accessories] cshehan:
The nook charger puts out almost 2A of power, where normal usb chargers and ports on computer only put out 500mA. The cable that the nook comes with has some terminations in it that allow the nook to tell when it is connected to the nook charger. It will charge at a much faster rate when using the combination of the charger and cable that came with the nook. Replace either the cable or the charger with anything else and you get low power charging mode which is very slow.
[Nook Color Accessories] adsbar:
Nook Charger

I keep seeing reports of people getting a fast charge using various other equipment, as long as the chargers are rated >= 1.9A.

Can anyone confirm or deny this? Any testing?
[Nook Color Accessories] FrayAdjacent:
As long as a charger puts out near 2A of current, it should work. The charger itself is just a four pin USB charger. The cable itself... lots of pins in the connector to the NC.
[Nook Color Accessories] adsbar:
That's what everyone's been saying, but it doesn't work that way in my testing. I have tried 3rd party chargers that output 2.0 and 2.1A, using the OEM cable. None of them are recognized as an AC charger. If we knew how the NC knows when it's connected to the original charger, we could find a way to modify something available at WalMart to quick charge our NC's. There's plenty of Ipad chargers (2.1A) available. The one I have doesn't work, though.

Alan
[Nook Color Accessories] cshehan:
Update to my previous post:

When I got home from work I tested my ipad charger (2.1A) with the nook color cable and it seemed to act like the nook charger. I did not think any charger but the nc one would work, but it seems it does.
[Nook Color Accessories] adsbar:
I am jealous. My Ipad charger (OEM) paired with the nook cable shows Charging (USB) under Settings --->About Tablet--->Status. I would love know how to get it to say Charging (AC) .

[Nook Color Accessories] deadbot1:
Keep your eyes open people...as soon as I return to work and have extra cash I plan on ordering and tearing down a charger and cable. Many have noticed poor quality in the chargers..I'm gonna try to engineer an open DIY charger and cable replacement with better filtering components. Hopefully will be creating a thread with full details in 3 weeks...
[Nook Color Accessories] bugeyed1:
YAY! I have my soldering station warming up.

Cheers,

kev
[Nook Color Accessories] deadbot1:
yep, this is overdue...plugged in last night...almost burned my hand after an hour of charging. I keep my charger by the bed and the hum is just annoying when I'm feeling a bit restless.
[Nook Color Accessories] cshehan:
Is there a way to identify problem chargers?

There must be some real inconsistency in the charger build quality. I've never noticed mine gets more than just a tiny bit warm and no humming. I wonder if there was a bad lot of them made? I was trying to look at the charger to see if there is a lot # or such, but can't tell what half the darned thing says. I'm posting a pic of the text on my charger in the hopes we can figure out if there is some way to identify problem chargers.

Edit: My nc came from WalMart.
[Nook Color Accessories] deadbot1:
Well there is a difference in the markings at least...The area circled in red...On mine it is R1101.

Still made in China;)

Edit: BTW my unit came from Walmart. Not sure if there would be any accounting for things like that.
[Nook Color Accessories] 12paq:
Sounds great. The simple tests I have done have yielded more quetions then answers.

Looking forward to your data.
[Nook Color Accessories] boogerboy72:
ive noticed i cant transfer data on anything other than the nook cable.
[Nook Color Accessories] swaaye:
The NC cable is special. It wont fit other devices.

described over here....

http://en.wikipedia.org/wiki/Nook_Color

Charging the NC on a regular microUSB means much longer time.
[Nook Color Accessories] deadbot1:
Yeah, this much is well known...my plan is to find out if there are "brains" in the charger or if it's just a high amp USB adapter. If the latter is true( which I suspect), then it's easy peasy to make a high power port( or just buy a quality one). If it has special circuitry...then I get to try and replicate it( with better parts) and release the plans so others can make DIY replacements.

Edit: I'm willing to bet that the extra pins in the cable are just to increase contact surface...to handle the higher amperage.
[Nook Color Accessories] Divine_Madcat:
That is totally wrong, since other cables WILL transfer data just fine. I use an LG Micro USB cable from my old dare, and am able to ADB push, install, etc just fine.

As it is, the large end of the Nook's USB cable is normal; this means that if the nook is communicating, it is doing so over the standard USB data ports, and not through some special connection. Keep in mind that some of the extra pins from the micro side are for the status light that is built in.
[Nook Color Accessories] neoshi:
Hmm R1102 here showing 1.9A output

I'm curious.. some people have talked about warranty replacements. What R versions are those?
[Nook Color Accessories] deadbot1:
Hmm....hadn't thought of that...that charger almost has to be dumb...just higher output...the smarts all have to be in the USB/power management chip in the nook. Those extra pins must be for the led and maybe a few for handling the higher amperage. Need to check out the spec sheet for that chip again...
[Nook Color Accessories] Divine_Madcat:
Why does it HAVE to be dumb? I mean, the charger needs to do nothing more than respond to a ping, saying "Hey, im a Nook charger, take me for a 1.9A ride!". I guess that makes it dumb, but no reason said technology won't be in the charger.
[Nook Color Accessories] deadbot1:
True..it doesn't have to be "dumb". I guess I am assuming based off of other remarks I have seen about certain Pie Filling Chargers working fine. It seems for those to be true that the only thing being looked for is a certain amperage. I really need a second charger and cable to tear down and answer this once and for all...work got pushed off another week. 6+ inches of snow where we are headed.

I wish that the photos from the existing tear downs were a bit clearer...I could tell a lot from looking at the traces.
[Nook Color Accessories] deadbot1:
Performing an experiment right now. Using the cable from my daughters LG Ally and the charger from NC. Battery was down to 10%. Will let it charge for 1 hour with this combo. Should answer a few more questions. If all goes well will next try to connect usb with same cable.

If USB works, then will consider tearing down my current cable.
[Nook Color Accessories] deadbot1:
Last night I did some impromptu testing. I let my nook get to 10% bat then charged using my daughters cable from her LG Ally. In 1 hour it charged to 24%

I drained back to 10% and used the stock charger with the stock cable...44% in 1 hour.

This further supports my thinking that the charger is "dumb" and the magic is in the higher amperage and extra pins in the cable.

Data was EXACTLY the same with both cables...310Mb file transfered with an average of 4 Mb/sec and peaks of 6.2 to eMMC. Did no charging tests off USB.
[Nook Color Accessories] Divine_Madcat:
Now, the other half of the experiment, would be to find a non B&N charger, that can do 2 amps, and try the same experiment. That will prove once and for all where the brains lie..
[Nook Color Accessories] Nilist:
Any 2A USB charger will do fast charging of the Nook Color IF you are using the original cable AND it is a Dedicated Charging Port as per USB specification (pin 2 & 3 shorted: D+ and D-).

http://en.wikipedia.org/wiki/Universal_Serial_Bus#Cable_properties

Many of the older iPhone chargers are not shorting the D+ and D-, but sets a fixed voltage level on the pins. That's why they don't fast charge, even with the Nook Color cable.
[Nook Color Accessories] combustiblemonkey:
It could also be that the light on the stock cable is just completing a circuit in the Nook, telling it to suck up more juice.

Thats lazy but... Well thats how I would do it. Im lazy tho.
[Nook Color Accessories] zavien3:
This is what I was told, I haven't tested it, but who knows....

"About your charging troubles: If you have the stock cable, you can charge at full tilt if you don't connect the data (2 center) pins to anything. Most of the cig lighter chargers have the pullups for iPhones which the NC doesn't like. So get a USB extension cord, lop off the plug end, and connect the red and black to a 2A 5V supply and leave the green and white wires unconnected."
[Nook Color Accessories] jsw31:
Here's what I've tested so far:

The Charger shorts the data pins. If you plug in to the nook charger you will find that the green and white data pins will show continuity. The charger does not send any voltage over the data pins. Using a usb extension and a scosche revive ii ipad car charger I was able to show ac plugged in and show ~+1200 ma current while in use with full brightness display (~+2a total). HOWEVER, this was with the stock nook color cable. Using a regular micro usb cable in the same setup still showed as ac charging, but with an amperage of ~-300ma. (~+500ma, same result as using a normal cable with the stock nc charger.)

So it turns out there is something special about both the charger and the cable. It may not be possible to get a "fast charge" without a OEM cable, but at least you can charge on the go with this method.
[Nook Color Accessories] iolinux333:
I picked up the b&n car charger at a brick and mortar last night. it's cute, charges FAST, solved all issues and it is expensive. -- bit it is less than all the money and time I wasted trying off brand chargers that never worked.
[Nook Color Accessories] heffe2001:
I tried my HTC Thunderbolt's charger, and no dice with a standard USB cable. I will try the nook cable plugged into it when I get home and see if it's any different. The nook knew it was plugged in, but wasn't charging, but didn't say discharging either...
[Nook Color Accessories] deadbot1:
Yeah, basically the special part is the extended length of the stock cable...it makes contact with secondary charging paths inside the nook. If you look closely at the end of the cable you can see 2 seperate rows of pins...need to get a second cable for teardown, but I'm sure that these pins are for the charge controller chip in the nook. A few for extra amperage capacity, a few for the LEDs in the cable. There might be a resistor in the charger as well that the controller looks for, to tell if it is an official nook charger.
[Nook Color Accessories] terryk88a:
I've ordered a "power filter plug" off eBay

I've ordered a "power filter plug" off eBay that is supposed to plug in between cable and nook, and allow charge even with low amp power source.

When I receive and test it with combinations of oem and vanilla chargers (hi/lo amp) and cables, I'll let you know if it was worth $6.50 vs $25 for OEM parts.

If you're curious, search for "Barnes & Noble Nook Color filter plug for USB charger"
[Nook Color Accessories] Phatdawg:
I hate to necrobump a thread, but I also don't want to start a new one.

I just tested another aftermarket 2amp usb charger.

It does _NOT_ charge fast.

After about 4 hours, I had about 27% charge from 0.

In 4 hours with the regular cable, I'm usually at 80%+.

So it seems the charger + the cable is needed.

I am wondering if the usb go between people are selling might be able to allow 2amp charge to flow fully.
[Nook Color Accessories] DiDGR8:
Even worse, this could be considered slightly off-topic, but there is something "special" about the microusb end of the cable (besides just the LED) if it gets damaged.

I break that end fairly often by dropping the Nook when I fall asleep with it plugged in. The end will bend several degrees but if it bends too far (or you try to straighten it back out), something breaks. The result is a red LED constantly during slow charging and then the red LED extinguishes when fully charged (no LED).

It's remarkably consistent. No orange LED, no green LED, no fast charge (but still will slow charge).

What I'd really like to see is a cable with a stronger/stiffer micro usb tip. :o
[Nook Color Accessories] Imbroglio:
How did that thing work out? I am wondering how well it works with external batteries.
[Nook Color Accessories] Phatdawg:
I'm curious too, I wonder if that filter plug allows you to use 3rd party 2amp sources at full strength like the stock adapter.

Zagg Sparq 2.0

Although this thread is old, I didn't want to start another one on a similar topic.

I've been searching for a portable battery pack for my NC, mainly for use as a backup battery when traveling.

The Sparq's output is 2000mA @ 5V and charges my NC to about 60% when plugged into the Sparq's "General" USB outlet using the original NC cord. Although I have not timed it, the Sparq seems to charge the NC at the same rate as the original NC wall plug. The Sparq also has an "Optimized" USB outlet designed for iPads/iPhones, but the NC does not support this feature so it sees the Sparq as a regular USB port.

The Sparq takes between 8-9 hours to recharge itself. This is not an issue for me since I intend to recharge it once I reach my destination.

The list price is $99.99 but it will be half price with free shipping on Zagg's web site on Monday and Tuesday. I do not work for Zagg but thought other NC users might be interested in my experience with this product.

I've had my defy sent to motorola repair centre twice and each time it took them around 25-30 ays just to repair my device and recieving and sending my devuice back took such a long time...in other words, i didn't have my defy for around 1 and a half month so now if i flash 2.2 (faster rom)..i want to be on the safe side so that i can jump back to 2.1 whenever i want.

I was recently told that...If i:

-do nandroid backup of my current 2.1 rom

-Then restore a nandroid backup of a 2.2 rom

I can gain 2.2 android froyo...and to get back to 2.1 genuine...

-i flash the 2.1 rom

-then restore my previous 2.1 backup

Are these steps correct to keep the downgradability??

Please i really need to get on with this problem...I don't want to be away from my defy for another month -.-

Did ATT release some sort of stealth patch over the weelend? As of Sunday morning my home button now links to Desktop Home instead of the standard Android home. My phone also gets stuck in landscape mode.

I am running stock froyo with root and clockwork only installed!

The funny part about this is I can restore to a previous saved backup and have it start in non landscape. But once I reboot, say goodbye to portrait mode. You get stuck in landscape.

Anyone else had this issue and fixed it?

No att did not send some update to you.chances are it is a messed up accelerometer for the rotation problem and possible a setting change or random bug that has affected the homer button
[Captivate Q&A, Help & Troubleshooting] tnerb123:
Well the funny thing is I do a factory reset and things are fun. No problems and every thing works perfect. Once i reboot after re-setting things up, it forces landscape mode and changes the home button. The accelerometer isn't broken. The reason I say this is because i can switch between between landscape and portrait just fine until I reboot the phone for the first time. If it was broken, it would not be able to do this.

One thing I am going to do is try and go back to factory in an area there is no service and see what happens. If it still does it, then I may be infected with something. But would be interesting since I haven't installed anything in weeks!

If ATT is sending stealth updates, then who knows what the heck they are doing with our phones!
[Captivate Q&A, Help & Troubleshooting] vunuts:
There are no stealth updates. Recalibrate your accelerometer and it will work fine again. I never had the problem on my Captivate, but once I upgraded my brothers to KB1, his had the accelerometer issue. Horizontal calibration in Settings>Display fixed it.

Well recalibrating did not work. Still stuck in landscape mode. Rebooting does nothing. Still trying to find a place to test the theory that I was on first connect with ATT.

One other thing. If I clear the delvik cache, it rests the portrait mode and switches correctly from there until I reboot the phone. Then it switches back to landscape only. This is driving me nutts. I can not get this crap to top happening.

[EVO 4G Q&A, Help & Troubleshooting] :
I flashed Amon_Ra's recovery some time ago using the PC36img.zip, and ever since, I can't get out of Hboot, as it keeps looking for an image. Going into Fastboot, I'm getting the same message as some have reported before:

SD Checking...

Loading...[PC36DIAG.zip]

No image!

Loading...[PC36DIAG.nbh]

No image or wrong image!

Loading...[PC36IMG.zip]

No image!

Loading...[PC36.IMG.nbh]

No image or wrong image!

I get this message every time I try to do Fastboot, and it simply pops back into the menu from there.

I have tried:

1. Reformatting my SD card to FAT32 (using the original card), and

2. Flashing a stock RUU back and re-rooting from that.

Both of these solutions coming from threads others have found to solve the problem, but I'm still having the same issue.

I had updated Hboot from 2.02 to 2.10 (probably a poor decision I now know), and the RUU flash says that it is now back to 2.02, but I don't know if I've still got lingering issues from 2.10.

Basically, I can't get out of Hboot without going into recovery and going back to a nandroid backup. This problem always pops up after flashing Calk's Format All (as it formats boot, I'm assuming).

I have 004 hardware.

Any help someone could lend me would be greatly appreciated.
