That doesn't matter.

If I can't even use the features because of problems with the service then what good are the extra features?

I have yet to have a conversation, via Facebook Chat, where either me or the person I am talking to ISN'T kicked offline at least once.

So I again state, the added features are irrelevant if you can't even use the service problem free.

The funny part is that, after Myspace resolved their issues, everyone moved away from it to Facebook which has nothing but issues.

Seems people like issues.

Side note: Most of those "added features" are spam and advertising related anyway.

If you do not log out of chat, the phone won't sleep. From the chat screen hit menu and log out. I figured this out right away after using other chat apps. If you don't log out the phone never sleeps for a lot of them. Push notifications my ass.

I know many people would enjoy this ROM, it's kind of like MIUI. The engineering rom was just recently released for the Meizu M9.

It can be downloaded here - http://www.hotfile.com/dl/85889655/e781655/update.zip.html

I was hoping someone could try and port this, as i dont have he knowledge. It would definitely be a top ROM.

Here's the Engadget article which shows features and stuff :p

WARNING: I've added this to my script and for some reason it has an adverse effect on the "n" button and Lock Screen if used BEFORE you complete the SetupWizard !!!

WARNING: Again BE WARNED if you do this mod before you finish the setup wizard you will loose the functionality of your "n" button and Lock Screen !!!

I have a feeling poster before me copied and pasted this from somewhere because notice how in his first sentence he says "Phone.apk and TelephonyProvider.apk" but then his script says "Mms.apk"....what happened to Phone.apk because there is no Mms.apk in the system folder on any Nook I have. So below is the corrected script and also this entire process in done in dos instead of in adb;

adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system
adb shell mv /system/app/Phone.apk /system/app/Phone.OLD
adb shell mv /system/app/TelephonyProvider.apk /system/app/TelephonyProvider.OLD
adb reboot

There is no adverse effect from doing this & it's confirmed after while in NookTools there is no Cell Standy service running.

Want to undo this process?

adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system
adb shell mv /system/app/Phone.OLD /system/app/Phone.apk
adb shell mv /system/app/TelephonyProvider.OLD /system/app/TelephonyProvider.apk

[Nook Color Android Development] DC_Rob:
I'm new here, but trying to learn.

Your code is:

adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system

adb shell mv /system/app/Phone.apk /system/app/Phone.OLD

adb shell mv /system/app/TelephonyProvider.apk /system/app/TelephonyProvider.OLD

adb reboot

would it make sense to add:

adb shell mount -o remount,ro /dev/block/mmcblk0p5 /system

before the reboot? Or does that get done automatically upon reboot? I assume it is bad to leave it rw and not reset it to ro?

Thanks for this, I ran 'most' of your other script.

Auto-nooter, your script, adw launcher and it is coming along nicely. Still debating remapping the volume keys to back/menu...

No such file or directory?

I keep getting an error message stating the following:

"failed on '/system/app/phone.apk' - No such file or directory"

If I navigate to that file using Astro File Manager I can see the files, so I can't figure out what I'm missing here.
[Nook Color Android Development] wvcachi:
Try capitalizing the file names.

Not to beat a dead horse, but this can easily be done in Root Explorer. All you're doing is renaming two files.
[Nook Color Android Development] crash447:
Not to be a cheapskate, but is there a free version of Root Explorer or a similar app that will do the same?

[Nook Color Android Development] RootNewbie:
What I ended up doing to rename the files with Root Explorer...

Hey everyone. After reading the thread I thought I would add some info that might help others. First off, when trying to download Root Explorer from the market, I kept getting an error that my credit cards were invalid. Apparently this can happen when dealing with apps that are not listed in your countries currency. So even if you are willing to pay the $4 bucks, the market may block you from doing so.

Anyways, after getting Root Explorer (RT) installed and navigating to the correct folder where the files were located. I was unable to toggle the r/o to r/w. After several reboots and wiping the data for RT with titanium backup it still would not grant me write access. So on a hunch I went and installed BusyBox, ignoring all the warnings the program spelled out at launch and continued forward.

After install was complete, Root Explorer finally let me change the folder to r/w and I was able to rename the apps. I believe BusyBox was still active in the background. Like previous posters - look at the first posts in the thread to find the files you need to rename and how to navigate to them. Also be sure to rename the file as others have suggested "filename".apk change apk to something else and leave the "filename" as is.

Hope this helps for people that are struggling with this like I was. I also have no idea if installing BusyBox helped or if RT just randomly started working...

Also, I've never used ADB to do anything on the nook color. I always install everything from the device itself.

[Nook Color Android Development] hvuong2:
Would this work on Froyo 0.6.7 CWM Image?
[Nook Color Android Development] HotShotAzn:
You all should read the entire thread. This was disproved. Removing the apks don't improve battery life as the NC does not have a cell radio.
[Nook Color Android Development] KararM:

Flux?

So uh, what are the last two items in your screen print, specifically the Flux Capacitor?

And i also am going to try this, b/c i tend to want to see it for myself, it's even more intriguing to me b/c there is such a 50/50 split in this thread of who believe it does something, and who don't.

Even with the improvement that is possible, if the percentage is appearing correct on all of our displays, which on mine is the same as one poster that shared their screen, its 69% of the batt being taken up, wouldn't the NC's be running so super slow, that in original ROMs (nooters) the developers created wouldnt they all have seen this being a big issue and just removed this functionality during the root image process?

That meter in the battery life setting must be a bad interpretation. Realistically wouldn't we all have to be constantly charging up the NC if that cell-standby was actually eating about 70% of power? If that is really costing us all of that, we'd be seeing it daily. Not having to "test" this out and leave the NC idle or what have you. True? Maybe it's just me. But i do want to try the rename, plus, buying Root Explorer will push me into trying other development things that i'm currently unfamiliar with but want to gain knowledge of. Now i have to find time tonight for it. Haha. Good thread everyone!
[Nook Color Android Development] xboxexpert:
Just for you, Done.
[Nook Color Android Development] bugeyed1:
It's been posted here before, but I can't find it. The way I see it, the battery use % numbers will always read 100%, or in many examples 102%. This is regardless of how much the battery is being drained. For instance, if the battery usage for a function is 50%, that reflects 50% of the total drain on the battery. If the battery has been depleted by a value of say 10% of its capacity, that 50% reflects half of that 10% value. The depletion of the battery could be almost zero & the usage numbers will still be 100% & 50% for the suspect function. At this time we don't have a tool that shows the actual drain on the battery. Say, something like showing the % of battery capacity used by a function or a measure of the actual current drawn by a function.

Cheers,

[Nook Color Android Development] jimlivingston:
I just read 20 pages and see no proof that this does not work. Where is the scientific methodology? There needs to be two identically configured nooks. One with this hack and one without. Both need to be fully charged and then unplugged. They both need to be left running and not sleeping. Perhaps running Pandora or something. After x amount of hours their battery levels should be checked and compared.

Relying a test of a single device while in its sleep state is not sufficient. I am smart enough to know many services are halted during sleep. For all I know, the cell service might be one of them. It may only run in futility when the nook itself is being used.

Now, unless my tired missed this experiment already being done, I am left with real world experiences; albeit not as reliable as scientific experimenting, but better than a non-scientific experiment.

Also, saying that the cell service program can't drain your batter because there is no hardware may not be correct. Programs DO drain batteries. Duh, right? I would think a program that is polling for hardware but never finds it, and thus runs constantly, would indeed drain batteries... fast.

Well, if the above experiment has already been done (twice), please someone enlighten me.
[Nook Color Android Development] obsidianblackhawk:
I have done this basically once, i can confirm from one trial that it makes no significant difference. Although i should try it twice for proof i guess.

Sorry for disturbing you your highness.
[Nook Color Android Development] djxcee:
Okay I did and it wasn't too much to ask for :p
[Nook Color Android Development] khaytsus:
Sure. Done. My wife's NC does not have the phone apk's removed, mine does. Hers shows the expected phone/cellular stuff in Spare Parts, mine mostly shows Android System as the top consumer.

Her NC uses about .2%/hr when it's asleep, or around 20 days standby time. Mine is the same when I disable my widgets. ;)
[Nook Color Android Development] jimlivingston:
Have you tried the expirement with the nooks NOT in sleep? That is the real test. I would expect that services such as the cell would be dormant, as it is sleeping.

If not, than your expirement is invalid, scientifically speaking.
[Nook Color Android Development] khaytsus:
Your argument is invalid, as what's showing up in Spare Part is Partial Wake Lock, which is only when the NC is asleep.

But anyway, yes, both of ours use approximately 8-10%/hr when in use. I could sit 'em side by side and measure them out exactly but that's pointless.

You feel free to do it and let us know.. :rolleyes:
[Nook Color Android Development] jimlivingston:
I appreciate what you are saying, however I have searched this entire thread and cannot find the write up or data from your experiment. I do not know if both your nooks are identical in their model, firmware, installed apps, running services, etc. That alone means your results could be invalid. I don't even know the procedures you took in your experiment, save that you tested them while they were in a state of lower power; which is not the state they really need to be tested in. And of course I have not seen anything about your experiment being replicated. That alone invalidates ANY conclusions you could draw from whatever experiment you have done.

The fact is any experiment needs to be done according to scientific methodology.

First, your control group MUST be identical to your variable group. Any failure in that and you have literally lost control of the experiment.

Second, the experiment MUST be replicated using the EXACT same experiment. Failure to do so makes your initial results inconclusive.

These rules are not subjective or prone to opinion. These are established guidelines set forth by the Scientific Community. I did not make these up. If your experiment does not conform to the rules, it is invalid.

So, as of right no, I see no proof that this does or does not work. All I have to go on is observation experiences of others, and the majority of those say it does work. Does that mean it does indeed work? No. I now also have my own personal experience, as I applied this hack. I am finding that my battery is lasting longer than it did prior to the hack. Does that mean it does indeed work? No. For all I know, an app I installed or uninstalled could be the cause of my longer battery life. I am not an expert on batteries. All it means is that any claim being made are inconclusive and invalid.

I would love to do the experiment, if I was the one making claims either for or against it. I merely pointed out that proof has not been provided to back-up the claims being stated.

If proper proof has been provided, as I already asked, please point me to it!
[Nook Color Android Development] chisleu:
What a thread...

Thanks for the instructions. It bothered me to no end to see those faux services represented in battery usage.

EDIT: The FP should be updated to rename the Mms.apk file too, which depends on telephony otherwise you get an error on reboot.
[Nook Color Android Development] NuShrike:
If you know anything about Linux and cpu idle states, the higher in the battery-use and the more % the "idle" process takes, the better.

Mine is basically 52% Display, and 9% Phone Idle (CM7). I would rather have it reversed.
[Nook Color Android Development] cephasara:
Possibly more than removing .apks

I don't know what to take from this thread now. All I know is that, regardless of if the OP's instructions really work, there is a way to remove "Phone Idle" from using resources. Perhaps there is more to it than just removing those .apk files.

http://tabletroms.com/forums/showthread.php?807-Cell-standby-services-removed-or-hidden-in-Eden-1.5&

Looking at the above link the Notion Ink tablet had an update that removed cell services and increased battery life, THEREFORE IT IS POSSIBLE. Maybe someone would like to take a look at the update removing cell service and the one right before it to see what else may have changed.
[Nook Color Android Development] khaytsus:
My god, let this thread die.

There is NO radio hardware in the Nook Colour. Therefore it will DO NOTHING.
[Nook Color Android Development] cephasara:
Please give some hard evidence with your hard claim. That, alone, has been the problem with this whole thread.
[Nook Color Android Development] rhester72:
This has been disproved at least a half dozen times through actual testing instead of guessing and "common sense". The burden of proof is on you - show through scientific testing that it helps and we will all become True Believers.

[Nook Color Android Development] cephasara:
Well the link I posted was suppose to argue the former, that through removing "Cell Standby" (possibly other files than just .apks--which was done though an official update) battery life increases.

Since it was an official update other things may have changed too, but it's worth more investigation.. I'll probably check it out more later.

[Nook Color Android Development] RoboRay:
Astro (like most file managers) does not ask for SU rights, so it is incapable of making changes to the system folder. Root Explorer can do this.

It is so much easier to do tasks like this with Root Explorer than with ADB or Terminal that it's easily worth the $2 or whatever it is for the app.
