USB Charging in CM10.1 - Nook HD, HD+ Q&A, Help & Troubleshooting

hi, i just installed CM10.1 on my HD+ and love it!! the only problem is that i have seem to have lost my ability to charge my HD+ while synced with my pc (debugging mode i guess). i have searched but i have not found anything that helps with the Nook HD+. so i ask here if anyone can help me out with some info. thanks in advance with any and all help.

I have a motherboard which can provide 3x normal USB power. It can only charge my tablets (Nexus7, Nook HD+, TF101 ...) while the screen is off.
I think this is normal. My USB ports can charge the Nook pretty quick.

hhmmm... thanks for for your input. everything seemed to work when i was running CM10. my HD+ charged with or without the screen on but since i upgraded to CM10.1 my HD+ doesnt charge when plugged into my pc. im trying to search for reasons why but still cant find anything.

I'm running CM 10.1 (6/30) build and it charges over my pc usb.
I did initially have a problem where it didn't recognize it as a storage device for copying files over,
but then I got it working. Not sure if it wasn't charging at that point but I think it was. Wish I could
remember what I did to get the mass storage working.

????? damn! i dont want to reinstall but if i have to i will.... you used the 6/30?? hhhmmm thats weird cause i used the same thing. is this what you used, [cm-10.1-20130630-UNOFFICIAL-ovation-emmc] ????? i would like to say that its no big deal but it kinda is. i used to charge while i loaded new comics, books & magazines. now i have to charge and load separately (yeah i know its not a big issue but i got used to doing both at the same time). btw, thanks for your input pdx!

Modify Clockwork to allow charging while off?

So I just found this:
http://forum.xda-developers.com/showthread.php?p=12513699#post12513699
and a modified version for my HTC Aria phone. It works great!
Is there any chance a dev here can modify CWM for eMMC to work in this way?
Pretty sure the Nook doesn't need any HTC hacks to charge while off.
isn't it an issue with the cm7 builds not being able to go into deep sleep (or having that option turned of or something?) cuz it causes problems with wifi?
i thought the not turning off if plugged in issue was related to this

Not sure if you were trying to be a smart-ass or not, but obviously my Nook isn't made by HTC, however if I plug it in while it's turned off, guess what, it turns on.
I believe it's a Clockwork "hack", not an HTC specific hack, but I could be wrong.

My HTC Aria is running CM7 and this hack worked perfectly for it.

That is because it is actually supposed to turn on when you plug it in. You should have it plugged in and then shut off to have it charge while off. No need for a HTC clockwork mod, as the problem was only with HTC devices.
I know you can turn it off after it starts charging, but it's not supposed to turn on, as you say, the stock Nook doesn't.

Yes it does. Plugging in any nook while off turns it on.
Really? Guess I missed that in the day or so that I had an unmodified Nook.
Still would like to hear from a dev whether or not the system could be modified to not fully boot when connected. It seem illogical to me to have a device as power-hungry as the Nook boot up when you want to charge it, which will slow down the charging process.

Day of stock? Pft 10 minutes.
But yes, it does seem completely bass-ackwards to have it do that.
Isn't this driven by the whole USB then microSD then EMMC boat loader? It makes sense to me that the device be turned on when plugging in USB if your first boot device is USB.
Ahhh... didn't realize that the Nook had USB booting, that would probably kill this. I thought it was just SD, then eMMC. Bummer.

It's not wifi it's the touchscreen and other parts go too far into sleep and will never recover. This has nothing to do with charging or recovery.

After plugging in the USB turn your nook off by holding the power button. It will continue to charge

It's a hack implemented by Clockwork to replicate the same behavior that the stock HTC recovery does on your phones.
Before this hack was in place plugging in your HTC Aria while off would force it to boot into recovery with no real reason. This modification just boots into a "off-mode charging" screen which was implemented using the recovery ramdisk and kernel but a different userspace program.
The Nook doesn't need this as it's implemented in hardware quite well.
1) The nook will turn on automatically.
2) There is not enough power the bootloader will display a screen needing more of a charge
3) It seems, based on my testing, that the nook will continue to charge even when the device is full turned off.
So in conclusionL I am glad it worked for you on your HTC Aria, but this hack is for specific HTC phones and does not apply to the nook color.

From the B&N Nook Color User Guide:
To charge your NOOKcolor from a wall outlet, do this:
1. Assemble the power adapter and microUSB cable. Insert the large end of the USB cable into the matching receptacle on the power adapter.
2. Plug the NOOKcolor end of the USB cable into your NOOKcolor.
3. Plug the power adapter into a compatible electrical outlet. If your NOOKcolor was turned off, it will now turn itself on.
NOTE: Depending on how much power remains in the battery, it might take around 3-4 hours to fully recharge
your NOOKcolor. Do not turn of your NOOKcolor while it is charging.
NOTE: Once your NOOKcolor has enough power to turn on, you can see how much power remains in the
battery by checking the battery charge indicator in the right corner of the Status Bar. You may need to
drag the green NOOK symbol to the right across your screen to unlock your NOOKcolor and display
the Status Bar, which runs along the bottom of the screen.
4. Once your NOOKcolor has fully charged, unplug the power adapter from the electrical outlet. Unplug the USB
cable from your NOOKcolor.

Seems like there is a design reason for that.
What? You can boot off USB too? I didn't even know that!
sorry, i was totally off i guess, thanks for the clarifications guys.
I've powered my NC off after i've plugged it in and have come back to an already booted device.
This is not once or twice, it's pretty much all the time.
Maybe i just have a weird device? I DID buy it off craigslist used... but i've had no issues at all as far as user functionality goes in the month or so i've had it.

I knew that, but was trying to avoid that step.
Thanks for all the info guys, I still think since the Nook does charge after powering off, it would be nice if someone could find a way to skip that whole boot/power-down process so I can just plug it in and walk away.

Are you running the stock ROM? Mine did the same thing until I installed a different ROM. HC and CM7 both stay off when charging after I have powered them down.
I've been running CM7 nightly builds off emmc mostly, if not the tablet tweak ones before they were integrated.
Not something I consider an issue for me, but I've yet to do any complete wipe since I first flashed CM7. I might try phiremod over the weekend unless the fascinate forum blows up with new stuff (our 2.2 source code finally dropped today), in which case I'll do a complete wipe and see if the problem persists.
EDIT: Yes, i'm running with the latest OC kernel
EDIT 2: Ok... I didn't notice before, but I guess I have a sort of faulty usb? not sure but it flickers from time to time, like on and off. I've never really paid attention to it while it charges, but i just noticed that the light on the N went off and came back on a few seconds later and confirmed that it flickers from time to time on its own. So on the bright side i guess i don't have hardware with an anomaly, too bad I have a charging cable with a mind of its own
Are you running one of Dalingrin's Overclock Kernels? I'm guessing not, since that would be the only other difference.

I've been plugging it in and then powering it off to charge. Now I find out that the guide specifically states to not turn off your NOOKcolor while it is charging.
Will charging while it's powered off screw up the battery calibration?
edit: one thing I've noticed is that if charging powered off, the usb light never turns green when it becomes fully charged.

[Q] CM10 on HD+ and HDMI adapter

I can boot into CM10 on my HD+. But when I put the HDMI adapter on, the HD+ reboots into the Barnes & Noble interface. Not really a question, just wanted to share the experience. Any chance this can be addressed in the CM10 development (or just low priority)?

You mean it reboots the moment you plug it in, or the moment you plug in an HDMI cable?
Does it succeed in booting all the way into the B&N stock image?
Thanks,

With the adapter, it boots into CM10. But when I plug in the hdmi cable, it immediatly reboots into B&N (well, it gets to 99%, white screen).
I've got the same issue. Has anyone found a resolution?
Using the 2/20 CM10 update with the hybrid installation, it reboots as soon as the adapter is plugged in and goes into stock. Mine doesn't hang at 99% though, everything is normal. That's 2.0.6 rooted, HDMI works great through that.

[Q] HP Touchpad Not Charging.

Hello guys,
I'm new here at the HP Touchpad Section and XDA-Dev Forums.
I am running CM7 on our HP Touchpad and my little brother has been fiddling with it(downloading many apps from the playstore using my personal account, thus forcing me to create a new google account/other shiz).
Then one time, the screen kept turning on and off without us even touching it. Our guess was it was dust on the screen which is being register as touch.
After a week or so that that was happening, the touchpad ran out of battery and was not charged right away.
The result, it won't charge anymore.
Is there anyway to open the device and shock the battery? It may be a dead battery just like what happened to my sister's iPhone.
I've also been reading some charging issues with CM7 and CM9 and tried some of their troubleshooting methods but non worked.
If I just get a little juice to boot it, I would reboot back to webOS as fast as I can and uninstall CM7.
Thanks in advance,
Raphael

Try leaving it on the stock charger for several hours, maybe days. If you have a touchstone, try that.
If you get it to charge (make sure it's fully charged), uninstall CM7 using acmeuninstaller, then boot into webos. If you have preware installed fine, if not install it and download 'remove android' (or something like that). Run it, then install either CM9 or cm10, using acmeinstaller3. There are several good how-to's which you can search for here or at webos nation forum.
When you have it installed, go to settings > storage and click on the 3 little squares on the upper right hand side, and click on usb computer connection. Then make sure the MTP box is checked.
Hope this helps. Good luck.

Thans for the reply chicle_11! Will try that on the weekends since I am very busy with school works. And thanks for the suggestion of installing CM9/CM10 but I will just stick to webOS and get an authentic Android Tablet(I'm choosing between Google Nexus 10 or Samsung Note 10.1).
I use webos at least 50% of the time. It's a shame that there aren't more apps compared to android. You don't have anything to lose by installing android. You'll have an excellent and unique dual boot tablet. CM10 is very stable now, I use it as my daily driver, I highly recommend it.

I still might reconsider flashing CM9/CM10 when I sort out the charging problems since I am just starting to save money for the Note 10.1/Nexus10.
Can you recommend a good CM10-based ROM for the HPTP or just the stock CM10 Jcsullins?
I use/recommend jcsullins' cm10.
Make sure MTP is checked (follow my first post) and that should take care of the charging problems.
Also, try to not let the battery run out of power. It could possibly brick the tablet.
It seems that I have somewhat sorted out the charging problems. I read an article last night that Samsung Chargers also work for the HPTP.
The process is fairly simple. Use the Samsung Charger first to charge a phone. After 2 hours or so, use that charger for the HPTP to charge the touchpad from a used/electrified wire. During the other process, use the HPTP Charger for the phone to power the cord up. After 10mins or so, switch both chargers. So the HPTP should be using the one that came with it by this time.
It worked for a while then the "Please use the charging cable that came blah blah blah to fully charge..." message came. I've read another article that the touchpad should be a little elevated or at least level with the cord so the cord will not fall down that is causing the message to pop up.
I've used both methods and the 2nd method is working like a charm. It shows a battery sign with a lightning bolt and the charging warning/message does not pop up. Will leave it overnight to see if it charges.
Then after, I might reinstall CM9(I've been from CM9 but downgraded to CM7 because of camera issues w/c my lil bro does not like).
So I left it overnight and it charged when I used the 2nd Method. Happy Days!

Sorry, That was late night here in the PHL and was a bit sleepy when I was posting that.
Also have dead touchpad
I haven't been able to see any life from my touchpad after the battery completely drained. Its been 2 days since I haven't been able to use it.
I've tried charging it via the cable and adapter that came with it for a couple of hours, left my TP on the touchstone all afternoon to morning and no life either, the touchpad however is a bit warm at the back. Does that indicate its charging?
my TP is sitting on the touchstone now but I've replaced the AC adapter and currently using my HTC Sensation plug, I am running out of ideas and I'm going to presume its completely dead.........
I've tried connecting it to the pc but nothing happens, Can someone help me out, I've also tried the button combinations "Home, Home+Power and Home+Power+VolumeUp"
I tried both of the methods mentioned a couple of posts ago with no success.
I have also left it on the regular AC charger for 48+ hours and a Samsung cell phone charger for another 48+ hours and nothing.
It is sitting on the Touchstone now for 36+ hours and nothing yet.
I sent HP an email and here is what they said to try:
"We gather from your mail that your Touchpad is unresponsive and will not turn on. To be able to help you with this issue please take note of the following troubleshooting steps:
First of all leave the device on charge with charger for 48 hours after do the following:
Press and hold the power button + Center for 15 seconds. The device may take a few minutes to restart.
Please do the above with the device connected to the charger. (not charging dock nor PC).
Press and hold the power button + volume Up + Center and continue holding for 5 seconds after the Full Erase screen appears.
Also please try the above steps with another USB cable, also please try to connect the USB to the computer with the touchpad, if the computer doesn't recognize the device, the USB cable is faulty.
Please try your charger on another device to see if this charges the device. As the issue could be that the AC adaptor that is not working.
Have you tried another charger with the Touchpad? In order to verify where is the problem. Regarding to your problem ,do you know if the problem is with the charger itself or with the USB cable? Have you tried the complete charger with another Device, phone?
If the steps given do not help you with this issue, please send us a Proof of Purchase (scan of store`s receipt attached to your response) to validate your warranty or the order creation date of your device and your address.
If you need further assistance, please reply to this message and we will be happy to assist you further.

None of that worked either. I just get the "Palm device" balloon on Windows XP when I hold the Power+Volume Up + Center button. It looks for drivers but never finds them.
Also try holding Home + Power button for 30 seconds instead of 15...This has been known to force some life back for some

Nothing after trying that and leaving it on the Touchstone for 48+ hours. Time to leave it plugged up to the computer for 48+ hours and see what happens.
Nothing after 48+ with the factory USB cable connected to a desktop computer.
It would be nice to see a solution that works every time instead of a bunch of guesses.

First my observations on three 32 GB TP's:
My discharge rate on WebOS in Airplane mode was arround -613 to -850mA. Screen on, (brightness affects this).
3. My discharge rate on CM10 in Airplane mode is about -520mA!!
4. A PC's USB port puts out 500mA's!!!
5. On the touchstone, (doesn't seem to matter if WiFi is on or off), with screen on 1/3 brightness + Battery Monito Widget = +853 to 945mA
6. On HP charger & cable, same as above = +1,377mA
What suprised me was the greater drain in WebOS.
You PC's USB port may be causing further discharge to the 2% TP's auto shut-off!
Actually none of these goofy button pressing and charging methods was right. A6 was faulty. It is fixed now.

My TouchPad discharged overnight and now just has a black screen. None of the button pressing or charging suggestions described in these forums has worked for me. I was just running webOS 3.0.5. No version of Android was on the TouchPad.
Please tell me the trick you used to revive your dead TouchPad. Was it just a problem with your Andriod OS?
Much thanks.

Well you tried everthing I've seen or could think of... though leaving it on till the battery runs out would be a curious test? If it will even do so.
Edit: You didn't state how long you tried charging it for. If it drained all the way it can take a good amount of time and WILL get stuck at only the backlight just like you have.. The charging symbol shows up later and will finally boot at around 15%'

Since i cant see anything on the screen i can only go by the light next the charging cable. I charged for for a whole day and the light was green on the tablet stating it is charged 100%. i did not try to drain it. will probably take a week or more since i unable to use it.
Unless someone has another suggestion i think it time to throw in the hat? the tablet is only 2 months old so it shouldn't be a problem returning it to the store and getting a replacement

I just researched info on the emmc brickbug in the event you were testing or running the rom with trim enabled. Or lagfix too. The brickbug can brick the device where it doesn't turn on. Just something else. Or that is from what I understand anyway.
But it sounds like you might as well take it in for replacement.

Nook HD+ not charging via PSU

Hi,
I just got my Nook HD+ yesterday and installed CM10.1.3 (stable) right away. Great job guys, the OS is really running nice and smooth!
However I've got an annoying problem (2 to be precise):
The Nook won't charge from the charger and the LED stays green. When rebooting with the charger plugged in it goes orange, but turns green as soon as the Cyanoboot Logo shows.
The only way I can recharge the Nook is via my PC (although painfully slow, had I not found verygreen's Charger Control tool).
This leads right to problem 2: The Nook is not recognized by the PC at all via USB. On some of my ports it shows up as an unkown device, but there seems to be no traffic between the two (PID and VID of 0x0000).
Both problem could not be solved by updating to CM10.2 M1 or wiping caches or data.
Any ideas on this?
Thanks!
€:I just tried reinstalling the stock im (from my cwm backup) to see if it works in there. Result: nope, same thing. Charging from the PC, but not from the wall, no USB connection. However after connecting to my wifi and reporting available updates the Nook suddenly rebootet only to get suck at a Cynaoboot screen followed by a flickering TWRP logo. Which is rather strange since I thought I had just installed a full backup thus removing both of those.. So I am guessing there is still some stuff gone wrong left on the device. Installed 10.2 M1 again afterwards.
So how can I make sure that I get back to a truly clean state on all boot-related partitions without having USB/ADB access? Which can be wiped from CWM or TWRP without risking a brick?
€€: Oh well.. I just set up a bootable sdcard with verygreen's 10.2 binaries on it and started the Nook from that.. Same behavior So it seems like either my hardware is bad (which would suck since I'm in Germany and shipping it to the US and back would cost more than the Nook did) or there is some serious weirdness going on...
