I searched, and did not find it in the zip, so I am guessing it is not there (unless like i was thinking, it was still in the apk)...

I guess once we get root, we will really know what .so files are there...
[Nook Color General] lschroeder:
Another issue for cm7, like the hulu enable version of libflashplayer.so, is that libflashplayer.so will be need to be reloaded with the proper permissions following a reboot of the nook. The directory containing the hulu version of libflashplayer.so is rewritten following a reboot. I used file expert app to copy from sd card and set the permission of of libflashplayer.so following each reboot.

For the hulu version to work it requires specific browser attributes as well (desktop and non-android identification strings). I know that we are trying to make hulu and other flash sites think that we are not coming from an android device. Not sure if they have customized the default browser for their specific version of flash.
[Nook Color General] dalingrin:
FYI, Its an apk in /system/app

Testing it now in CM7

EDIT: Cool, got flash working with DSP accel.

EDIT2: It has A/V sync issues at full screen though. A/V sync is fine not full screen. This is stock kernel haven't tried overclock.
[Nook Color General] lschroeder:
Did you just stick the FlashPlayer.apk in the /system/app folder and reboot? Is there now a libflashplayer.so file in the /data/data/com.adobe.flashplayer/lib/ directory?

I guess if I put the hulu version of libflashplayer.so there I would loose the DSP accel. I am using phiremod V6.1 with your 4/23 OC. Making a Nandroid backup now.
[Nook Color General] dalingrin:
Its as simple as grabbing the apk from 1.2 and installing it via a file manager.

Playing a flash video now uses only 40% CPU at 600mhz.
[Nook Color General] lschroeder:
I am able to make the hulu site work with this version of the flash player by replacing the libflashplayer.so file. What app do I use to get % CPU and speed? I want to compare flash video between the hulu libflashplayer.so file and the libflashplayer.so file that FlashPlayer.apk created.

As I suspected FlashPlayer.apk overwrote the hulu version of libflashplayer.so, but I could manually change hulu's libflashplayer.so back. The permissions for libflashplayer.so were slightly different with the 1.2 apk.

How to install update...

Best method seems to be to remove any SD Card completely before updating the stock software to 1.2.... In detail:

(Internal memory of Nook must be stock for this to work)

Power down Nook

Remove Micro SD Card

Fully charge Nook (to be safe)

Download the update Zip from B&N on your computer (http://su.barnesandnoble.com/nook/n...i5g0hg39C2QaLD9nH4HY/nookcolor_1_2_update.zip)

Connect the Nook to the USB Port of your PC (2 new drives should appear in the OS. Open the 2nd Drive. {The 1st new one won't open anyway, and thats ok})

Copy the Zip file as is to the root of the 2nd drive.

Wait 30 seconds after the copy is done. (This makes sure cache is empty.)

Cleanly dismount both drives. (I usually close all windows, then open "My Computer", and right click on each drive letter of the nook and click on "eject". Again the 1st drive may have nothing to eject but the 2nd one will.)

Disconnect the USB cable.

Your Nook will likely reboot itself in the next two minutes, then upgrade itself over the next 10 minutes more or less.

Nook will reboot itself to latest stock 1.2. (Takes a bit longer than it used to with 1.1)

You now have about 200 apps available to download (most of which are not free) and Flash.

When you are done testing, power down the Nook, and re-insert the MicroSD card.

Boot whichever OS you would like, you are done! :D

Wow! I am glad it was easy!!!! Hulu plays amazingly smooth now.
[Nook Color General] s52m3:
Is it working for you on stock 2.2? Mine says unsupported when I try to play any video on hulu.com
[Nook Color General] lschroeder:
You changed the libflashplayer.so file to the hulu version and corrected the permission. Is that correct? Are you using Opera Mobile with the changes? If not, how did you make the other browser work? Do you know a way to check CPU usage and speed?
[Nook Color General] Divine_Madcat:
Did you also grab the libflashhwrenderer.so, or were you just using the APK?
[Nook Color General] bekyndnunwind:
Hey Dalingrin,

Just wondering, when you say it has sync issues at full screen...would you say the performance is better or worse than the regular flash 10.2?

Just wondering if I should keep the version of flash we've been using, or go ahead and try this omap version?

Thanks again for all your excellent work!!! :D
[Nook Color General] tphone:
Thank you. I had CWM installed, so the official update failed with signature check. But I could remove CWM using this monster pack : http://legacyschool.us.to/nookdev/clockwork/rootpack-instructions.html

and then did the steps that you listed and got the official update working. It's really impossible to brick the Nook Color as many people have said. I think that B&N save themselves a lot of support calls in making this device so easy to hack and restore.

Found this external battery with good pricing. Anyone tried this? Does it work with NC?

monoprice.com/products/product.asp?c_id=108&cp_id=10833&cs_id=1083311&p_id=7664&seq=1&format=4#feedback
[Nook Color Accessories] Jgrimoldy:
It certainly should work.

The connections are a little confusing. The male micro-USB coming off the top suggests that you need to connect it to your nook, which would make the whole thing a little unweildy. Also, how is it charged? From a PC? From a AC/USB adapter?

I bought a couple of these:

http://www.dealextreme.com/p/usb-re...emergency-power-with-cell-phones-holder-44749

They're only 2000 mAh, but you can connect them to the nook with the proprietary nook USB cable. Even though they're rated at 1A, my nook recognizes as 2A...

Bonus: built in fold up wall charger.

Not-so-bonus: DealExtreme ships from Hong Kong. Delivery time is measured using the geologic time scale.
[Nook Color Accessories] johnny15:
I actually have one. It works with my EVO, but not the Nook Color. You can look at the reviews for the item and see others have similiar issues with other micro USB devices. I think I'm going to order a M/F micro usb extension cable from ebay....hopefully it helps this work with my NC.

Micro USB M/F Extension
[Nook Color Accessories] dennisi01:
Johnny,

Are you sure its not charging? The output of the device is 800mA, and the output of the stock charger is 2000mA. So although it may be charging slowly, the nook would not report it as charging. Would you be able to plug it in and leave it for a while and see if the battery% increases?
[Nook Color Accessories] johnny15:
I'm positive it's not charging. The micro USB seems to be slightly different than "standard" and thus, doesn't fit all the way into the port on the NC. I can try one more time when I get home today, but I don't think it'll go.

I wish this wasn't the case and I've tried it a handful of times when I first bought it. I've only been using it on my phone lately...
[Nook Color Accessories] dennisi01:
Ah ok - if you get the cable and it works let us know :) It is a good price even with the cable (about $20 total with battery shipping and free shipping for cable), and if that works it would be pretty sweet!
[Nook Color Accessories] johnny15:
I'll keep you posted. I had been debating whether or not to buy the cable, but for $5 and I can extend the use of my charger, I finally figured it'd be worth it....that and the fact that I want to help people out here so no one buys the charger itself thinking it'll work.

I ordered that cable yesterday, so when I get it (from China) I'll let you know whether it works or not.
[Nook Color Accessories] ks88:
I'm interested to know too. Thanks alot bro! :)
[Nook Color Accessories] jemping:
Ok. I got that battery from Monoprice, and it charges my nook without any hassle.

Just need to be a little bit precise on plugging it into the micro USB female on the nook.
[Nook Color Accessories] johnny15:
Well, mine does not....wonder what the difference is???
[Nook Color Accessories] rcboosted:
I'm interested in a similar charger, but with 2400mah.

http://www.dealextreme.com/p/2400ma...a-cable-for-htc-desire-g5-samsung-i9000-57905

Does it work with your android phone? A lot of after market chargers makes the touch screen unusable while charging. Does it work both while plugged into the wall and using the internal battery?
[Nook Color Accessories] RASTAVIPER:
Interesting topic.

Let me see if I got this straight.

This device has double function?

-If Nc needs charging, U just plug this device and U can have extra power on the move?

-Also, it gets connected to normal wall plug and through this U charge your NOOK?It can work as alternative nook charger (but for sure in slower rate)??
[Nook Color Accessories] lesdense:
I bought an Energizer XP2000 for about $35 at an OfficeMax (they're widely available). 2000 mAh capacity, weighs about 2oz, comes with its own cord with six different ends for different devices. I plugged it into my fully-charged Nook at 10,000 ft out of Seattle, watched non-stop video at 70% brightness in Airplane Mode for nearly five hours to Baltimore and still had 58% battery left on my Nook (the Energizer was discharged). Other chargers in the line go up to an insane XP1800 that'll power a LAPTOP for six hours!

The sweet spot for me is probably the XP8000. It's max output is 3500mA vs. 500mA for the XP2000, it's the size of two iPod Classics stacked on one another but weighs a little less and it should keep me going for a looong trip. It's $100 so its not an impulse buy (at least for me) but seems like an essential tool for the long distance traveler.

[Nook Color Accessories] Jgrimoldy:
I use this with my nook. I can't answer any questions related to workability with Android phones. That's not this forum.

While using this device to charge my nook, my nook is completely usable. It will charge my nook when the device is plugged into the wall. It will also charge my nook when it's not plugged into the wall (it is a battery, after all). In either situation, my nook is completely usable when connected to this.

I use this battery with my proprietary nook charging cable.
[Nook Color Accessories] rcboosted:
Thanks for this report. My nook goes crazy when I use the same aftermarket charger that makes my phone unusable while charging. It acts as if someone is hitting the screen randomly very quickly. If you're not having issue with the nook on this charger, I'm confident it won't have issues with my phone either. I will order 1 and find out for sure.
[Nook Color Accessories] d.v:
Wonderful report. I'm in the market for an external battery. A couple of questions if I may.

So one of the 6 tips works with an NC? I thought the NC's cord and tip were special to enable the quick charging. Do the Energizer products support this technology?
[Nook Color Accessories] RASTAVIPER:
At dealextreme there is also 3000 battery. Why not using that?

The bigger the better right?
[Nook Color Accessories] lesdense:
The micro USB tip that comes with the Energizer works fine with the Nook. I don't know about "fast charge" vs. "slow charge" and all that but it definitely works. One SUBSTANTIAL advantage of the XP2000 over the larger capacity models (of the Energizer line) is that you can use any USB-to-mini USB cable, including the one that comes with it, and plug it into either a USB power plug adapter or a USB port on a computer to charge it. The XP4000, XP8000 and XP18000 all require their own power adapter. It's included in the purchase of course but I don't like carrying around another cord. Not a deal-breaker, just a factor.
[Nook Color Accessories] johnny15:
Well, I said I'd update once I recieved my extension cable, so here it is...

I finally received my extension cable and it allows me to use my Monoprice charger with my Nook, so that's great. In the end, it wasn't needed. I ended up RMA'ing my charger back to Monoprice because the thing had a dull buzz when not being used and a high pitch noise when either charging a device or being charged. I'm happy to report that the new charger works with or without the extension cable on my Nook Color and on my EVO 4G. In the end though, I like the extension cable because it gives me more flexibility when using the charger.

Here are the links again...

[Nook Color Accessories] d.v:
Got it. The slow vs fast charge would be a good thing to know. Can you time a charge with the Energizer unit and one with the stock NC charger? If it can fast charge, the Energizer would make a great addition to the NC.

Thanks either way. The info has been helpful.
[Nook Color Accessories] rcboosted:
Can you link us?
[Nook Color Accessories] RASTAVIPER:
Sure,

lets say this, this

or this at 3.200
[Nook Color Accessories] lesdense:
Each of these options has pluses and minuses. The reviews at each of the links say as much. One of the batteries you linked to has retractable power "prongs" so the A/C adapter is built in, a great option. Another has a proprietary power cord and the third has no charge status indicators (minuses, IMO). All of them are a little heavier than others I've seen, but only by an ounce or so. They are certainly cheaper than brand name alternatives. I won't be the first to plug no-name power sources into my electronics but I appreciate the feedback from users who do.
[Nook Color Accessories] rcboosted:
Ah, I've went through those too. I've issues with their 5.5v output voltage. That means the phone/nook will have to dissipate that extra voltage as heat. At best, it'll heat it up more, worse, it'll be over the spec and burn something out overtime. I have no way for sure to know if that's the case, but I'm sticking with 5v output voltage. I love the extra capacity though.

i go on long trips that I might not have a wall plug in (bicycle touring). I have two of these bad boys:

http://www.epowerpad.com/model/PPD130.aspx

they power the nook color and all of my phones no problem. each battery has 2 usb ports to charge and one cable to charge my laptop. It's a lot of money, but I can charge my nook color 5 times over with one of these.
[Nook Color Accessories] d.v:
Pricey but thanks for the link.

Do they "fast charge" your NC like the stock charger does?
[Nook Color Accessories] bigted41:
very pricey, i got them from work for free, just thought i'd make people aware.

the charger is slow, i'm not using the nook cable and charged 20% in 2.5 hours.

I picked up one of these a few years back for a trans-Atlantic flight to keep my iPhone, PSP, etc., alive as long as possible:

http://www.lenmar.com/Web/ProductDetails.aspx?ProductID=PPU2400B

It's worked quite well for me and seems to provide power to the Nook just fine by plugging its own USB cable into the battery.

I think I got it at Fry's for ~$25 at the time. I'm sure there are plenty of other options on the market now, but these general types of solutions seem to work great.
[Nook Color Accessories] Stev3-o:
What about these 8000mah, though I can only imagine using them on long distance trips.

You can finally wear that sweater with the custom made pocket for Ipad but only to hold the charger:D

Maybe able to power the Nook one and a half charge or a few good charges on the cellphone. Charge to full is about 4hrs. There's a discontinued 30 pin female to female usb converter to enable dual charging.

[Nook Color Accessories] jared_c:
One of the things to keep in mind about the fast chargers is that they do something funky with the data pins to indicate that they're not a computer. USB devices have to ask permission from the host computer to increase their power draw above the default level, which I think might be 100 mA. They're also limited to a maximum of something like 500 mA. AC adapters do something funky, like short the two data pins together, or to ground, or something along those lines to indicate that they're not a computer and you can draw as much as you like without asking permission. If that's not implemented on the aftermarket charger then the USB device, like the nook, won't draw more than 100 mA so as to stay compliant with the USB spec.
[Nook Color Accessories] Stev3-o:
Does the Nook do fast charges through the AC? I ordered an external battery travel charger+USB port for my Samsung Captivate and I'm going to short the data cable to enable fast charge.

Will this fry the Nook as some devices can't take 850mA input?
[Nook Color Accessories] Explore3:
I ordered the monoprice charger. Relatively small and light plus it works! I found the connection between the charger and my nook and phone were a bit of a pain to use while traveling. Therefor, I ordered the ebay cable.

On an overseas flight, I might just plug the charger in when I drop below 60%. This would slowly recharge the unit while I am using the nook. However, I am hoping that recent advances in battery life will force me to repurpose my nook battery backup charger to a battery backup phone charger.
[Nook Color Accessories] rcboosted:
I got my 2400mah charger. It worked with my Epic and Nook without causing touch screen issues. New lithium batteries need a few cycles for all the capacity to be realized, so I did about 5 or 6 50% discharges over the past week. So here's my test result:

At 25% batteries left in my Epic (1500mah lipo), it charges it to 100% taking 2.5 hrs. That makes it around 450ma charging current by my estimate, not counting efficiency. If I take 80% efficiency in the phone charging circuit, that makes it around 560ma charging current.

The charger has 3 leds which blinks in sequence according to capacity during charging. I'm assuming 3 led means full, 2 is at 66%, and 1 at 33%. Since you should NEVER discharge a lithium battery beyond 80% of their rated capacity, I stop discharging it soon after the last led started blinking. Which surprisingly made some interesting math. Assuming 2400mah is the true capacity of the battery in the charger:

2400mah x 80% (never discharge beyond 80%) x 80% (charger circuit efficiency) x 80% (phone charging circuit efficiency) = 1228.8mah.

which incidentally is very close to 1500mah x 75%(my phone stage of charge) =1125mah. Very close to the above! Of course all of the above are without a shred of proof, and it's backed up by flying monkeys and unicorns. But I do know this, the charger will charge my 1500mah Epic from 25% to full without damaging the cell in the charger.

There's my review.
[Nook Color Accessories] Explore3:
Given your estimated "true" capacity of your 2400mah charger at 1229mah, does it make sense to use it as a charger for the NC? The NC has a 4000mah battery will having the charger make a significant difference? Of course the same question can be asked about my purchase of the monoprice 2800mah charger.

I am going to see what my battery life is after I upgrade to the new kernel. If it does not improve, I will consider this one (after finding out the weight). I think if you used the Nook charging cable you should get "standard" charging times.

I tested the 2400mah charger with my nook last week, and I can get about 25% of the nook charged when hitting the last led on the charger. It seems to charge faster than using a regular usb cable and a standard iphone 120v usb adapter.

I would say bring it on your travel as a supplement charger. You can use it to charge all your USB devices and use it in emergencies. A super capacity battery powered charger will need to be plugged into the wall sometime right?
[Nook Color Accessories] RASTAVIPER:
I didnt see that somewhere.

So, how many hours more can you use nook with this battery?

Sent from Nook Color on Phiremod 6.3 @1.3Ghz
[Nook Color Accessories] lesdense:
This question -- how many more hours, is how I look at the value of external batteries. Sure, you might be stranded somewhere and have 2-3 hours or more to recharge your Nook with an external battery, but a much more important factor for me is how long I can extend the battery life of my Nook with an external battery. As I wrote in a similar thread some time ago, I bought an Energizer XP2000 for about $35 at an OfficeMax (they're widely available). 2000 mAh capacity, weighs about 2oz, comes with its own cord with six different ends for different devices. I plugged it into my fully-charged Nook at 10,000 ft flying out of Seattle, watched non-stop video at 70% brightness in Airplane Mode for nearly five hours to Baltimore and still had 58% battery left on my Nook (the Energizer was discharged).

Starting years ago with PDAs my strategy on trips was to use external batteries right from the start so when I got where I was going I didn't have a dead phone or PDA. If I have no other choices, at the end of a trip I want my external battery to be dead, not my internal.
[Nook Color Accessories] lschroeder:
+1 I did the same thing with my original ipod touch. I bought Just Wireless SKU 10047 at Target on clearance awhile back. It says Output 5V=1A. Does anyone have any experience with how long this one will last playing back videos and what Battery level the nook will be at if it starts at 100? I have the 4 LED's full charge and can connect it to my nook with its micro usb connection. Just have not tried to drain it yet?
[Nook Color Accessories] lesdense:
Just a heads-up. When I searched this manufacturer and model number on Amazon the product that came up, a small device external charger, had the worst reviews I've ever seen on Amazon. Ten reviews, all from different people, over a 2 1/2 year period, every one a one-star (lowest) rating with damning commentary. Maybe I found the wrong product, maybe the reviewers are wrong, but FYI.
[Nook Color Accessories] rcboosted:
Isn't how many hours you can extend the internal battery ENTIRELY dependent on how you use it? With the nook off, I can extend it for days, with it playing some intense 3D games, maybe not so much. How can anyone answer the question: "How many hours can you extend the battery?"

The charger I got gave me 25% more out of Nook's internal battery. You do the math on how many more hours you can get out of it. To make it simple, if whatever you do on your flight drains your nook after 10hrs, then this will give you 2.5 more hrs. if you drain it in 5 hrs, it'll give you 1.25 more hrs.

It's like asking, how many more miles will 2 more gallons of gas give me? Well, it depends on how you drive it, and how many passengers you've got in the car.
