So what would happen if I just started deleting BN apps ... - Nook Color General

... from /system/app
Which of them would save me some resources (assuming I don't care about the built-in nook functionality), and which of them would make things go kablooey?

Why do you think they would save you resources?
Plus I think you might want to avoid doing that until there is a full ROM and Recovery, if you screw up /system I think you're hosed.

Without recovery it is possible to brick the NC by deleting stuff as previously stated.
I did try some cautious renaming of B&N stuff with the end result that while the NC worked, it showed as not registered and this made it a bit difficult to de-register and reset...
And not only did the B&N stuff not work (since it wasn't registered!) there were a few other glitches as well.
As a note from my earlier Android experiments: if you do want to try getting rid of something, don't delete it! Renaming it is just as effective and has the added plus of being easily restored AS LONG AS THE THING STILL WORKS AT ALL.
I usually append .bak to things like text messaging, facebook and twitter since I don't use or want them.

/system can be recovered regardless of changes to the file-system as long as you don't play around with the factory fallback stuff which is on a different partition completely. The minute you start messing with that all bets are off.
The /system partition will be restored if the device doesn't boot 8 consecutive times.

Well, so far I've deleted the library, the shop, the built-in app launcher and a few other items with no ill effects (other than, you know, not having the library and the shop). I got rid of one that looked a little borderline scary -- but I'm being a little reckless here and didn't note the name. Maybe a BN specific applicationservice apk?I think that's why selecting settings from the B&N bottom notification bar doesn't work anymore (but selecting settings from within Zeam gets me there). Got rid of the home apk.
I know, I could play it a lot safer just renaming these things. But I'm living on the edge (besides, I could always get back to a stock system setup if I screw things up badly enough to force the 8 reboots).
I'll soon look at this a little more methodically and see if there are any B&N-related services running that I don't think I'd really need ... then go for them too. After all, just deleting things that may or may not be running from boot ... it's a fun reckless experiment, but it doesn't necessarily save any resources (other than space in system).

If you manage it I would be interested in knowing about it- especially if the Nook for Android app can be installed and actually work, afterwards!
That had been my goal when messing with it.
Methinks I found one too many packages that had "bn" in the name for my own good. lol

Upgraded from Fresh 2.0d to Fresh 2.1.1 without wiping, everything seems fine. Is it?

Last night after it was found out the leak and the official release were identical I loaded Fresh 2.1.1. I realized as it was loading I forgot to wipe the phone. I figured I'd let it finish and just have to redo it, but I turned my phone on anyway, just to see.
Everything seems fine. The update seemed to leave everything in tact, while running fine. (and freeing up 55mb of space for apps despite seemingly installing the same apps and leaving mine) The update worked, there are noticeable style differences in quite a few places.
My question is, is this an illusion? Am I not really running the updated versions in some areas? Are there behind the scenes things going on that make it error check and fall back to old "backward comparability" type things, make it slower, etc? Or is wiping just a "safety" thing to give you the best odds of success?
Is my phone going to burst into flames in my sleep, or did I get lucky because most incompatibility examples would be obvious?
I'm not using apps2sd.
Wiping is a safety thing, and also required if there are major changes between versions.
If it is working then don't worry about it. I have flashed 2.1 ROMs over each other before without any problems before, for example a Damageless's Rom over Flipz's. I think as long as the framework matches there is likely to be no problem.
I found one thing that doesn't work. The people app force closes every time I go to actually view a contact.
Does anyone know a good way to clear the contacts without deleting them? (If you delete them in the contact app google syncs the deletion, as it should.)
Actually it looks like it's only a problem on the contacts linked to facebook. Maybe if I can find a way to unlink them, and then link them again, without opening them, they'll be fine.
Just had to removed and re add my facebook account. Good times. So maybe people don't need to redo their phone to jump from 2.0d to 2.1.1. Give it a try.
You've inspired me to give it a try. i, however unlike you, do use a2sd and it's picky as **** so hopefully that stays in tact.
I'll post results after.

Unmodified gTabs

Not only am I a newbie, but I am also a timid newbie. I am reluctant to mess around with the stock software, and OS that came with my gTab. Most of the great apps, and advice on this site requires you to either flash the tablet, or root the device, etc. I am WAY too chicken to try this. I would love to be able to get to the usual Market as I can on my phone. I would also like to use Swype. Is there any way to "open" up the tablet to these without "major" surgery? I think a list of apps that can be manually installed would be helpful to inexperienced "chickens" like me. Or any add ons, that might improve our new baby would be most appreciated. Thanks in advance.

Why would I pull the Tegra out just to flash a rom?
PS there is a reason that thread was on page 3 as there are fewer that are not flashing roms.

I just did the 1.0.1-3053 update, and it appears all previous changes remained. I did have to re-root it with the z4root app. Those complaining of problems after this update seem to be running a customized ROM. You won't have these problems unless you flash a customized ROM.

This whole argument is ridiculous. Not a single rom has done a single thing to the underlying "Stock" structure. They are all based from the original "Stock" stuff. The only thing they do is either add or subtract from the original base software.
There is no magic here. If you buy a new car and put shiny new wheels on it you have done the same thing. The car still has the stock engine, and basic structure. If you bought a house that was painted pink and didn't like how it looked you might paint it. Same house, just a new look.
So, your stock with tweaks is essentially the same as my stock with tweaks. I just choose to install the majority of the tweaks at one time with a simple rom update. You do yours one by one..
I don't care what anyone does with there tablet as long as you don't use it to start World War III. But the my mods are better than your mods argument is kind of silly.
Do whatever makes you happy. All I can say is that pretty much no matter what you do it can be put back to original in about 5 minutes. Boot loops, hangs, funky looking screens.. All part of the learning process. Some people seem to be more prone to it. Most of the issues I see people have come from them getting in a big hurry, not thoroughly reading the instructions given with almost every mod, and then flashing away. Slow down, read, and understand what you are doing and it will all typically go just fine.

Not true.
Some of the mods are based on the zpad image, a completely different image than the g-tablet. My only objection is people saying flashing custom ROMS is a must. That is nonsense, and I will say so every time I see someone post that.
The more updates that ViewSonic put out, it seems the fewer "tweaks" that will be needed.
Can we keep the trolling to World of Warcraft?
There are minor to major changes that can be done ROM wise. What is important IMHO is to give choices to someone that is just starting.
I have the impression the op would like TnTLite version vs Vega or Cyanogen or even ZPad.
I did start like you... almost happy with stock. But the more basic things I needed I noticed the original TnT wasn't good enough. I have changed to TnTLite myself and couldn't be happier.
Just check that thread. Its one stop and change.
Good luck
Bingo! Choice is king, if you don't like the choice you choose go back to stock. But atleast show all your choices, we are not all wanting the same build, hence we are not talking IPADS.
Thanks for the suggestions, everyone. I gather that rooting the gTab is not such a big deal after all? I had started with the impression that rooting and flashing the rom were similar, and equally "dangerous". I DID find the thread that copc referred me to after my starting this thread. We all have to start somewhere as newbies. Thanks too to Wasserkapf for his help.
Rooting will still allow you to get all VS updates. Same with doing the Market install.
Flashing a ROM can be scary, especially if you have lots of stuff on your tablet. I found that investing in Titanium Backup (requires root) was a great idea. I do a full backup every time I flash my ROM and restore apps and data afterwards; I have never lost data nor settings.
If you decide to flash TnT Lite or VEGAn (which is coming along nicely and really brings the tablet to life IMO), there are not only many posts but many friendly folks who are here to help you out.
I am very happy with my G Tablet and this community has been immeasurably helpful in making it so useful.

Exactly we all start as newbies, and it's places like this that are great help.
Good News, everyone. I used z4root, and was able to root my gTab. I also was able to install Launcher Pro, so that now when I turn it on, I get the option of going to the old familiar Android layout as on my Droid. Thanks for the encouragement from you'all. The sky did not fall. Yeah!
I do have some questions, though.
1. If I accidentally load in the TapnTap home screen, I cannot get back to the launcher pro. I cannot find it on the tablet to run it. I can find the apk and it offers to install it again. So, can anyone tell me where it is hidden?
2. I downloaded the vendors apk in an attempt to get the old android market place as on my phone. But it will not install. I am sure I am doing something wrong.
3. There are some icons to the right, the web, messages, and the phone. Is there a way to remove the ones that do not work? Only the web works. I understand that the phone would not, and even the messages. But how can I remove them?
Again, thanks for the moral support and encouragement. I still find the structure of the tablet confusing. Internal SD, external SD, root, etc. Anyone out there with the technical know how could make quite a few dollars by writing a book explaining the wonders, procedures, and pitfalls of our new tablet.

On my tablet, just hitting the Home icon in the upper-right corner will do that. It is the second one from the top, on the bezel of the screen.

You should be able to drop a different icon, from the main screen 'Desktop' on top of it, essentially replacing it. To get different icons on the main screen, open the app drawer, and tap and hold an icon. To remove it from the main screen, tap and hold, and move it to the trash can on the right.
I got as far as downloading the zip file, unzipping it. But I am not sure what "mount as R/W" means. I am also not up on the structure of the storage of the Gtablet, and my computer sees .android_secure, Android, Backgrounds, backups, DCIM, download, and Lost.Dir. As a result, I am not sure where to copy the new files to. I moved the unzipped file to the download folder on the tablet. But I am not sure where to go from here. Being a newbie bites.

I thought that the instructions were as clear as anyone could make them.
3. Using AndRootFile or any other file manager that supports root access, mount as R/W, and copy the contents of G Tablet\permissions to System\etc\permissions.
Click to expand...
Click to collapse
That means to use a file manager that supports root browsing. The stock one doesn't, so you will need to install one. The link in the original post will get you the AndRootFile app, that should work. I purchased RootExplorer from the Android Market, so that is what I use. It has a "Mount R/W" button at the top, and I assume AndRootFile has something similar.
Oh, and root is to Unix/Linux/Android that Administrator is to Windows. You need root permissions to make system changes.
Once you have mounted it in R/W mode, copy the files to the folders that it says to. When done, don't forget to re-mount it in R/O mode before exiting.
My bad. I had used z4root to do the rooting. I'll try it with the one you suggested. Thanks.
Actually z4root should work for rooting the tablet. But it isn't a file browser with root access. That is where the other apps come into play.
OK. Here is my adventure so far. I got AndRootFile, and installed it. It is now working. But when I try to copy a file to another location, it does not want to copy the file. features.xml is an example of one that it shows the check box for copying, but when I get to the destination, there is nothing to paste. Frustrating. I also tried Rootexplorer, and have the same result. Now it looks as if the other new file in the new permissions folder copies, since it says it exists and do I want to overwrite. I said yes. But the second file, features does not show up even after I try to paste it. The good news is that I am figuring out the structure of the Beast, and so can move around much easier with AndRootFile, and RootExplorer. Thanks for your ongoing patience, and support.
It doesn't sound as if you are first mounting the file system in R/W (Read/Write) mode. And when finished, make sure you mount it back into R/O (Read/Only) mode before exiting.

Captivate boots slow, issues. How to troubleshoot?

So, a little history...
I'm on my 2nd Captivate (unrelated issue). The boot problems didn't arise until I restored my data onto it. The first time I tried restoring system data along with my apps (which I figured was safe since I was going from 2.1 stock to the same) but that had lots of issues. So I did a factory reset, and started over. This time I just restored apps and their data, and a few specific pieces of system data (contacts, wifi APs, etc). That worked better. But later I got too aggressive with what system apps I "froze" (using Titanium Backup), and it got into boot loops I couldn't break out of. So I did another factory reset.
This time, first I carefully froze only apps I was to confirm were safe to freeze. I didn't proceed restoring my apps until I was done freezing and ensured it was booting fine. I then restored all my apps (and their data). The problem is now that it takes forever to boot... in fact, it'll go into a boot loop if I just leave it be. It seems the only way I can gain access is to try and unlock it before it's done booting, clear any "Force close" errors (sometimes takes a few tries) and given enough attempts, I can get in. But the boot takes an unbelievable amount of time, and even with my original apps is many times longer than before on my previous Captivate. Once I fuss my way in, it seems mostly fine, but something is obviously wrong and I want to get it straightened out.
Aside from doing another factory reset, and reinstalling all my apps (which takes like a day without troubleshooting after each, since batch restores in TB don't seem to work well on the Captivate so I have to do them one by one), I'm hoping there's a way to troubleshoot it in its current state and try to fix the problem surgically versus erasing and starting over. I looked at the logcat logs but got in over my head... there are so many errors and warnings and I don't know what's normal and what isn't... too many to know where to begin with searching Google.
So... advice? What tools are available? Even the logcat doesn't seem to kick in until the boot is mostly done, so I'm not sure if it can catch the problem while it's happening. One frustrating thing about Android is that is seems to have no "safe mode" or other diagnostic boot or full logging where you can methodically look at what's happening and experiment with the config. If this was a Windows, Linux or FreeBSD box I'd be in my element and able to get to the bottom of this, but on Android I feel even more crippled, locked-out and helpless than even on Windows. Urgh.
There's got to be a better way to troubleshoot and fix than endless random factory resets. This is something us anti-Windows people scold PC makers for, with all their use of "Restore CDs" for every minor and trivial software issue.
Thanks!
I can't help but think you are still disabling some essential system apps. Either that or one of your apps is causing major problems. Please list what you have frozen in tibu. Btw, the batch function works fine and is what most people on here use.
Also, what is force closing after you restore your apps.

I also tried removing my MicroSD card, as well as switching back to Touchwiz (from LauncherPro). Didn't help.
Yeah the batch problem in TB is very frustrating. I'm using the pay/donate version so I'm missing out on a feature I paid for. I've been exchanging emails with Joel (the author) and we haven't figured it out yet. Batch backups work fine. Batch uninstalls also work fine (update: phone just spontaneously rebooted after about 50 or so uninstalls in a batch). It's the batch restores that seem to choke it. It's not corrupt backup files... a verify runs fine, and I can individually restore the same handful of apps one by one that will choke and hang/reboot the Captivate if attempted to restore in a batch.
The FC error I get is on boot-up, as I try to unlock the screen prior to the boot finishing. I often see "Process system is not responding".
I have aLogcat installed, if that's any use. A few questions about that:
- What's the best logging level to view on? In other words, do I care about "Warnings"?
- What errors are common, harmless, and safe to ignore?
Currently I've tried uninstalling everything down to just a few core apps. Certainly boots fine now, but I get plenty of warnings and errors in logcat.
Are u restoring just the user installed apps+data, or system apps too? Or restoring system stuff like contacts data, accounts prefs, etc?

I did not do a "restore system data" or any batch/bulk option in TB that restored all system data. As I recall, the only system data I restored a-la-carte (by selecting the individual item from the TB list) were:
Accounts
Bluetooth pairints
Bookmarks
Calendar
Contacts
Wi-Fi Access Points
These were all items in green in TB. I don't believe I restored anything else. Possibilities I suppose are wallpaper settings, "Country, Launguage, Time Zone"... but I definitely would not have restored anything not green.
Are these items safe? Is there any system data definitely not safe to restore? I have to wonder though, if "system data" is unsafe to even restore to the same stock OS version... why back it up at all?
I'm not a long distance from doing yet another factory reset I suppose, if it must come to that. But I'd love a way a bit more analytical/exacting to try and troubleshoot this other than "reinstall one app, reboot, see what happens" as that will take me a week to get back to where I was. I also suspect it's not just one single app that would suddenly show a huge difference after installing, but instead might be the cumulative errors from several apps and knowing how to identify that and clean them up would be useful.
Using adb logcat you can view what is occurring while the phone is booting and possibly see where it is hanging or what is causing the slow boot times. I have seen problems from restoring data such as accounts and contacts with titanium backup but does not seem that it should be an issue when using the same system though I have very little experience with the stock firmware. I know it is not an answer to your question but it seems that you are wanting to remove all the att/Samsung BS so why not flash a rom that does this as well as much more?
Sent from my ADR6300 using XDA App
Thanks for the tip about adb. I've actually not needed adb for anything yet so I've never set it up or used it. I wasn't aware that the service would be active early enough on the phone's boot process to allow it to log boot logs... nor was I even aware it could do this. I'll definitely check out how to set this up... however, if you have a free second and can point me in the right direction (FAQ, instructions, etc) it'd certainly be appreciated otherwise I'll search around and try to find it.
I could probably find other ways to restore contacts and could set my accounts up again manually but I really doubt that's the cause and the other ways are sort of a pain and imperfect. Since neither of us is really convinced that'd be it I won't bother yet until/unless you really suspect it.
I wondered how long it'd take before someone would suggest a custom ROM, this being XDA and all. Short version is I'm not really sold on the concept, as they are all based on the buggy beta leaked ROM, or 2.2 ROMs from other devices that have been hacked up to sort of work as well as possible on the Captivate. All seem to have issues... enough that I'm not really left feeling confident about them. Seems every release unleashes new issues despite addressing old ones, and all seem to have at least a handful of gremlin items that just don't work quite right. Don't have a warm fuzzy feeling, and I still feel like Samsung is going to release an official 2.2 for the Captivate within the next month or so, so I'm interested to see what comes of that. If nothing else, it'll give a better baseline for custom 2.2 ROMs. Then there's the 2.3 being worked on... now that might be interesting.
I don't really think my issue here is related to me running 2.1.
On my phone so it is a pita to search and add a link for you but search for android sdk and you will find what you need to get adb up and running.
And as far as the rom issue goes..it is your phone and I respect your concerns I just had to ask
I would think its media hub that slows it down. It will search your SD cards on every boot. I would start there first.

That's one of the apps I've frozen though.
For me the longest process while booting is the stupid media scanner upon bootup. Takes FOREVER for the phone to finally "boot" all the way up.
Been looking for a way to disable it (not really lol) and only have it scan manually to see if the boot time will improve. I'd start searching there.
Also - from what I've read nothing you did should have affected the phone. BUT - if your using Google for your Calendar and Contacts.. and they all get synced up to Google? Why bother doing the restore for those? After you sign up with the Market they get pulled back down to your phone automagically
It's definitely more than just the media scanner. I watch that. When everything is loaded up, it actually reboots in a loop unless intercept the FC. The media scanner will rerun over and over each time... far more than the standard two times.
And I use Google Calendar for my events, but I keep my contacts locally on my phone.
So what is the FC again?
Yep.. my media scanner will run at least 3 times before it stops checking everything.
Very frustrating that the software does this EVERY time I boot back into my phone - you'd think a programmer would put a check to see if it had run before or make it user configurable to scan when you want it to.

See my second post (reply #3):
"Process system is not responding"
LOL sorry not enough coffee and a lil' guy that decided to wake up at 4a.m. = not a good mix.
Well.. did the ol' wise search of Google and came up with:
Might be a permissions issue. Easiest way to fix it is to run ROM Manager and have it fix permisions.
Run the command yourself in ADB:
Code:
Open terminal and
>su
$mount -a
$fix_permissions -r
The -r is optional, but necessary if you find orphaned apps (the app not found please reinstall message)
And reboot. That may help.
And it was also stated that you might have an errant widget/application causing the issue as well. That will be fun trying to figure out what it is.
And.. from my non-dev/non-professional experience - I have checked the logs on my phone and do see a large number of warnings on the phone - but never hindered performance.
So.. 99% of the time you can probably ignore them.
But back to the FC issue - I would try doing a restore of your apps/data again (I read where you have it back down to the "core) and then run the permission script or have ROM Manager do it for you and see if it returns.
Just an update that I think the "fix permissions" thing solved most (but perhaps not all) of my issues. Thanks so much for the tip. I've been reinstalling apps in batches and it's much better, although I see it getting bogged-down bit by bit and I can't pin down what or why.
Thing is, the apps I'm installing in these later rounds/batches shouldn't be resident all the time, shouldn't be auto-loading, and don't come up in things like Startup Cleaner or Advanced Task Killer. Nor do the various process monitors I've tried seem to have the granularity/ability to catch them while they're happening.
So things are better, but I still have some issues without a suitable means to diagnose. I don't get why just having more apps installed, but not running, should affect boot time so much. Hmm...
An inability to troubleshoot certainly rains on my love-affair with Android... not that I'm jumping to another platform anytime soon, but I really want this to work well (as well as be a good salesman to friends and family who often turn to me to show off quality technology).

[Q] Removing Un Needed Apps/Services on NC running CM7

I did search and most of the threads refer to actual Phones.
I have a Nook Color that I am currently using the SD Boot method to run CM7. I want to cut out all the stuff that really has nothing to do with basic reading and Internet activity if possible. Like the dialer, and voice, text to speech, basically anything that relates to text messaging and phone calls.
Is there a smooth way to do this that won't result in a bricked SD OS?
I thought of using Titanium Backup to just "Freeze" anything I didn't want but I don't know if that will even work.
Is there a list anywhere on here of what can commonly/easily be removed and still maintain a "tablet-like" functionality?
thanks in advance for any suggestions or links!
All evidence indicates that removing these services (usually be deleting the .apk files) has no impact on performance or battery life, and may introduce compatibility issues with apps that expect to find them.
Don't worry about it. The apps being there don't hurt anything.

See the CM wiki
I removed Bluetooth stuff, cmstat, telephony.apk, phone.apk, setupwizard, setup, and a whole host of other services I don't use. Why do I need blue tooth when I am not going to use it. Others will say there is no harm and battery life is not impacted...probaly true. However there is one one benefit that cannot be ignored...it gives back memory to the nook that was not being used.
EDIT My roommate and I discussed after I posted and he said just leave it alone. No harm done. I said true, but he removed bloatware from his phone...and other apps he did not use or need. Then I replied, why can't I do the same thing. If i am not going to use it, or its not needed, makes sense to me just remove them. BTW, I used root explorer to remove the apks. Its been a while since I did it and never really had any problems.

Rooted, now what?

I got a new wifi S2, installed the permissive kernel and rooted it. I installed TWRP and made a backup. Now I've got an uninstall app and I've removed a few things; primarily Knox and the security logger so that it quits whining at me. I have a strong desire to never ever use the cloud, create a Samsung account, or a Google account. I really just want to load some books onto it and DLNA some music and videos.
So I want to get rid of all the stuff that I'll never be able to use but it's not clear to me how to identify all that. I'm a long time Unix guy but not at all an android guy. If something prompts me to create an account I know I want to uninstall it, but damned if I can figure out how to identify what to uninstall from what icon I touched.
I've found bloatware lists but they're all somewhat old and not for the S2, so it's not clear to me if I should trust them. I'd like to avoid trial and error "uninstall and reinstall if something doesn't work" or the even more dreaded "uninstall and find out six months later that something doesn't work". Can anyone point me at a good list of what I can remove, or where I can figure out how to determine that for myself? Thanks.
Better start freezen apps instead of uninstalling them. I use titanium backup for that, but you can use whatever you like. Just be carefull freezing or uninstalling OS related apps, you can end in a bootloop, but you always have the odin flash method to reflash your system back to normal. Just don't play around with partitions or /dev .
Right now I using my tablet unrooted and untouched, so I can't be more specific which apps you can freeze without problems.
He doesn't need odin as he has a twrp backup.
I take it you are using System App Remover (root) to uninstall system apps? If so you are pretty safe as they are backed up and can be restored any time if something goes wrong.
Also are you aware without a Google account you will lose part of the functionality of an Android device?
Samsungs account you can do without. All that stuff related to it can be deleted, but don't advise removing any of the Google core services from the stock rom.
If you really want a GAPPless rom then you're better off with a non stock custom rom like CM or AOSP.
Not much in that area of development at the moment, but there are a couple of members working on it.

Yes, thanks. If I lose functionality to avoid Google watching over my shoulder I'm all for it. I'm old and probably overprotective of what's my business and not theirs. In truth, I bought the S2 because I have a collection of chess book pdf's and djvu's that I want to be able to read while I'm sitting at my chess board. I got the 9.7 inch S2 because the old eyes aren't what they used to be. Anything I can do beyond that is icing on the cake.
I do have the app remover, and I've removed the stuff that was obvious to me (like the Microsoft Office stubs). But there are still lots of things that bring up a prompt for an account when I run them and it's not clear to me how to figure out what app to remove to get rid of that particular thing. On Linux I could use rpm -q to figure out what rpm contained a file I want to remove and I'd be good to go. I've tried googling some of the app names but the "descriptions" I end up finding are particularly unenlightening. And since this is definitely not my area of expertise I don't really want to operate in "let's remove this and see what happens" even if I can reinstall the app from its backup. I've been doing software development and sysadmin for more than 35 years now and that just doesn't seem like the way to approach this.
I was looking at CM, which seems like it might be what I'm looking for, but it's still in alpha and my skill level is probably not up to coping with that so I'm back with the problem of how to decide what to get rid of.
