Hy
Is there a way to link our external SD to internal storage?
I've tried:
Code:
cd /mnt/sdcard
mkdir sdcardname
mount -o bind /mnt/external_sd /mnt/sdcard/sdcardname
The following command works but it gets lost after a reboot.
Symlinking with ln -s doesn't seem to work- It gives a "link failed Function not implemented" error. Busybox is installed.
symlinks (ln -s) doesn't work because /sdcard is fat32. It doesn't support symlink. You can indeed mount the external_sd underneat /sdcard, but as you say, it's lost after reboot. You have to do it everytime you boot.
The only other way is if it's supported with a custom rom.
Blast. Then I'll probably format my card to EXT and mount it like that,
I didn't know that I can't mount FAT.
EDIT: Success! It's possible using Tasker and Locale Execute Plug-in. Now the card gets mounted at boot and you can transfer files directly to it.
Ok here are the results after some testing:
+ SD card is now a part of internal memory so I can save an view files without messing arround
+ You can copy files directly to SD now without jumping through hoops
- You have to have a rooted tablet runing Tasker and Locale Execute Plug-in which is quite a lot for a simple fix
- PC doesn't see the files you copy to your SD through the tablet even though it sees the files that you've transfered through PC. Both are seen on the tablet though.
I can provide instructions if anyone is interested.
I'm interested.
Ok you have to install Tasker, Locale Execute Plug-in and root the device.
Then:
- Make a folder on your internal memory where the files will be located (SD in my case)
- Go into Tasker and click on New
- Click on Event/System and select Device Boot
- Click on New Task and press OK
- Click on the + button and select plugin (if you don't have any plugins listed you didn't install the execute plugin)
- Select Execute and click on Edit
- Type (without quotes) "! mount -o bind /mnt/external_sd /mnt/sdcard/SD" (replace the SD with your folder name)
- Click on the menu button and you'll see a bar which will be empty. Just click on the last button and you'll see that the command is saved.
- Now click on Done twice and you're set
Reboot the device and check if it works.
Thanks so much for this. Now I never have to remove my micro-sd card. This is huge!
hi... this is great..,
but 1 questions
1. does it effect when clockworkmod read the external sd ?
The script runs after you boot Android (when it comes to the lock screen) so no it shouldn't affect anything because the bind doesn't work after a reboot.
That's why I use Tasker to run the command. Tasker actually only enters the command for you (previously I had to type the command manually).
tried this and excellent,
but what about the battery ? is the tasker application eating battery much or not ?
whats youe experience?
I have it on my tablet and my phone and I never noticed a drop in battery consumption so I think that we're talking about minutes here at most.
PC actually sees a CramFS userspace partition, which is an image of /data/local/

Whatever I try, i cant get it to work. If i enter the command in tasker:
! mount -o bind /mnt/external_sd /mnt/sdcard/SD
it shortens it to:
! mount -o bind /mnt/external_sd /mnt/sd
What should i do so tasker understands/saves/remembers the complete line?
Are you typing it in Tasker or Locale Execute Plug-in. Because you should use the latter.

Me too So should I typing it in Tasker or Locale? I don't have Locale.
Sheesh guys. Just follow the post #6.
You need a rooted device and Locale Execute Plug-in. Locale Execute Plug-in is not Locale but a plugin and a free one as that.
Follow the instructions. They are clearley written and you should have no problems. Just don't skip steps.
You are the best Thanks for help. I forgot about su premission (What a shame).
My 3.1 is rooted, i have su access, and it even remembers it.
I type the command in the locale plug-in as per instructions on the first page.
But still it abbreviates the command.
And if i attach the Iconia to my pc, and open the Acer Iconia icon, its empty, which means, i think, it points to a non-existing directory?
Any help would be appreciated.

Off course it does. It just points to an empty map if the command isn't entered properly.
I don't know about abbreviating the command. It works fine on my Acer and on some others that reported good results.
Edit: But when you enter the command.... Do you see the abbreviated command in tasker or in plug-in if you return to it? Because Tasker won't show the full command only a few words but you should be able to see the whole command if you click on Edit and check it in the plug-in.

You should click "allow" in Locale Execute Plug-in when superuser ask you about it and don't forget about spacebar between:
mount -o bind /mnt/external_sd(here spacebar)/mnt/sdcard/SD

How to remove unwanted stock/preinstalled apps
This is not a question. This is howto
I DID search through the forum and found nothing but
Q: how to remove/uninstall preinstalled apps ?
A: no way !!!
WHAT ??? WRONG ANSWER !!!
Here is how:
First of all I’ll describe my rooted, of course, phone configuration, so if you are on the same boat you can do same trick 99% if not you’ll know where to go
- CyanogenMod 4.1.2.1 (this is latest experimental as of sept-05-09) –works very stable for me
- 4GB SD card partitioned: FAT32, ext3 (512mb), linux_swap (32mb)
(great guide how to part your sd here: http://androidcommunity.com/forums/f56/compcache-userinit-22465/index4.html#post232988 (page 4)
- CompCache with Backing Swap (here: http://androidcommunity.com/forums/f56/compcache-userinit-22465/index4.html#post232988 (page 1)
Requirements:
1) G1 rooted phone
2) Explorer with ability to explore /system folders – I use Astro (market)
3) PC/MAC
4) SDK installed on it (http://developer.android.com/sdk/download.html?v=android-sdk-windows-1.5_r3.zip)
Steps:
1) first and very important: full backup of your system.
- DO NANDROID (it’s preinstalled in Cyano, search forum for “nandroid” if you don’t have it)
- DO ext3.tar (if you use ext3)
- Make full SD copy to your PC
As described here: (yes, same tread, thanks to bdb4269) http://androidcommunity.com/forums/f56/compcache-userinit-22465/index4.html (page 4)
Now we are safe..well, almost
2) find full name for the application you want to uninstall, say for Amazon MP3 it will be com.amazon.mp3.apk
I did it like this
- open Astro explorer
- go to the very top (/)
- search “amazon”
- when search done, write down full app name
- long press trackball – chose – open containing folder – remember the path (ie /system/app)
3) Assume SDK and USB drivers are installed ( http://developer.android.com/guide/developing/device.html )
And phone is connected to pc/mac
= below guide is from http://oneclickandroid.blogspot.com/ with my comments =
- Start emulator (don’t think it is necessary, but lets follow – emulator located in SDK folder\tools\emulator.exe in my case C:\SDK_15\tools\
CMD window pops up for a second and disappeared
- open CMD prompt (in Windows: Start > run > print: cmd , hit OK/enter)
- execute "adb shell" in on terminal from SDK_ROOT/tool folder
(if you did not register SDK folder in windows variables you need to cd to this folder first:
print: cd c:\sdk_15\tools hit enter
print: adb shell hit enter, you’ll see new prompt appeared: #
- print: mount -o remount,rw /dev/block/mtdblock3 /system
This will mount your system folder with read/write permission
- go to system/apps folder of your phone
(print: cd /system/apps hit enter)
*** guide says “/system/apps” but in my case it is “/system/app” ??? (remember I asked you to write down full path and name from Astro ? check your path first ***
- print: rm yourunwantedapplication.apk
i.e. rm com.amazon.mp3.apk hit enter
now, check installed apps in your phone (no reload req.) – is amazon disappeared ?
I wish to try this with app for that has a replacement from the market, like
Dialer – aTakePhone or Music – Meridian etc
Hope someone brave will do it before I do
Deleting may be unsafe if other preinstalled apps or process have links to uninstalled app
What happens in this case? wish someone knows the answer.
I dont think this trick will speedup your phone if you've moved your apps to ext2/3/4 already I just dont want to see useless apps in my phone/pc
Please reply here if you have experience of deleting preinstalled apps
sorry, english is my second languague
Good luck !
Hahahaha... all that trouble just to install a few unnecessary apps off of a ROOTED phone?! If you had searched, you'd have seen the numerous posts where we've posted instructions on uninstalling apps through Terminal. Literally 4 lines of code at most! Note that you can do this with any app you don't want. I have xROM, and one of the first things I do whenever I clean install to the latest version is replace ringtones and remove apps, including HTC Mail, Email, Amazon mp3, and Android Music. It takes me about 2 minutes to remove these apps.
Example for removing Amazon MP3:
su
mount -o rw,remount /system
rm -r /system/app/com.amazon-mp3.apk
mount -o rw,remount /data
rm -r /data/data/com.amazon.mp3
exit
exit

That's not how you start the emulator, in the window that disappears is a message telling you to start with the proper parameters, which you'd see if starting from a command line. If the emulator actually was running, then all your adb commands would then fail because it wouldn't know what device you wanted to address, you'd have to use "adb -d" to tell it to use the real device rather than the emulator.

Thanks for the info.. guess I've been doing an extra step, but this means I can do I through terminal even faster.
Easy way to remove unwanted preinstalled apps
Use Root Explorer to browse to /data/app_s and find the applications you don't want. Delete the APK and ODEX files and you are done.
Always remember to make a backup of your phone, before you start deleting.

The app_s folder is only used for Hero ROMs because there isn't enough space in /system, so it's placed in /system/sd (the mount point of the ext partition) if you have an ext partition for A2SD.
For regular google source builds just go to /system/app.
there is an app called rootexplorer it has a button to remove syatem apps. real easy to use. http://www.cyrket.com/package/com.sp...e.rootexplorer

Sorry to kind of hijack this but cyrket.com always shows as a blank page.
anyone know why or how to fix that?
i think simply deleting the apk files and data folder will keep an entry in some kind of registry in android. if i just delete the apk files and data folder and run fix_permissions, it shows the same number of processes.

is a rooted file browser and it is, by far, the easiest way of uninstalling any stock apps.
Click one button to make the system folder re-writable (same thing with data folder, just a button), navigate to the apps directory and just delete. or you can search for the app and just delete it from the search window. Voila!

are you talking about rootexplorer or what? elaborate a little..
i just bought and downloaded/installed rootexplorer simply to delete stock apps. upon opening it ask me to allow it. i say yes and it says my phone isn't rooted.
weird.. i just upgraded from cyanogen v4.1.999( or something around that) to the newest 4.2whatever. so how if my phone not rooted?!

I have everything... titatium, terminal, root explorer, etc etc
with terminal I also receive "directory not empty", but with root explorer I can delete the apk's from /system/app ... I confirm after that they are not there, bus as soon as I reboot the phone they come back.
what can I do ?
I have HTC desire with stock android, rooted .. and also a couple of programs I instaled I don't really knwo what they do.. like rom manager, clockword recovery, etc

It is because the full url path is not correct. Hover cursor over link and look at lower left corner to view the url path...it has those .... in it and will not work. We need the full exact url path.
just use titanum backup,rt click on application it will show (remove),be sure u didn't updated any stock app e.g gmail update
Regarding using Root Explorer on stock G Tab updated to 1.2-4349...
Trying to remove some of the apps preloaded and using Root Explorer get a statement - my phone not rooted.
I want to get the apps off. What to do now? Thanks http://media.xda-developers.com/images/smilies/smile.gif
Thanks for this clear procedure !
Hey All,
I was trying to find a way to make a symbolic link to the SD card so all the movie programs could see it. On a FAT32 it looks like it isn't doable. You can, however, bind mount to a folder.
Here is the info. Credit goes to korora over at modaco.
You have to be rooted for this to work(or so it seems)
Pop open the terminal and enter the following code:
Code:
cd /mnt/sdcard
mkdir fssd
mount -o bind /Removable/MicroSD /mnt/sdcard/fssd
fssd is generic and can be named whatever you prefer.
Now to find your sd card in a program that can't access /Removable/MicroSD just navigate to /mnt/sdcard/fssd
hope this helps.
Wow, this is sexy! Thanks for this, I have only just done it and a quick poke around with ES File Explorer, but it also is nice because I can just open ES, it defaults to sdcard, so I scroll down to MicroSD (the directory I made) and there it is! I know it only saves me 2 taps of the screen, but still, it's nice. So I say, thanks for bringing it to my attention, as I don't follow those boards.
Thanks,
this is great and works perfectly!

No problem. Glad i could help
amazing how quickly threads get buried here.
Now to add it to the autos execute shell script so it binds every start up.
Neat! Makes me wanna root now Wonder if you could do the same with say a 500GB external USB drive
This is great but we need app developers to now start allowing us to select where we want app data.

Look for Script Manager in the market.
But I have another question: how can I have programs to save their own settings in this new links/directories?
I do not want to copy it by hand.....and I want to let software recognize their saved settings after a reinstall/restore....
Nice job,this works great,thanks.
sorry for the noob question...
where exactly to put in this code?
i tried making new script with the Script Manager and run it but it says:
CD: not found
mkdir failed for fssd, Read-only file system
mount: no such file or directory
but if it worked this workaround would've been great though
This is what mine says when I open up the script:
#!/system/bin/sh
mount -o bind /Removable/MicroSD /mnt/sdcard/MicroSD
This is with my directory named MicroSD of course. The first line was there when I made a new script so I left it. Not sure if that helps. I already made the directory so I didn't need that command.

i was trying to figure out where to put the mount line. Thanks, it worked great with script manager.
I'm trying to wipe and format a microSD card that I have plugged in via OTG and already have it wiped with this;
Code:
dd if=/dev/zero of=/dev/block/sda
Now I'm looking into how to recreate a MBR and partition table and it says to use the parted command, which I'm glad about as I'm familiar with the command from using Ubuntu but it's not installed and I can not find any instructions on how to get it. Can anyone explain how to install it? I know I could just plug the SD card into a computer and do it but I'm having fun doing all this on a tablet. Lol
Bump
Anyone?
I have got the same question, any other solutions?
This is the most complete information I have found yet, but it doesn't work. Either from me messing something up or it not being correct for the Nexus 7 being that it was made two years ago. http://www.droidforums.net/forum/htc-droid-eris/78650-internal-storage-partitions-screwed-up.html
I pushed all six files to /sbin/ with no errors and changed their permissions with no issues but I restart the tablet and none of the six files are in /sbin/
Just for the heck of it I extracted the six files to the SD card in the tablet, CD'd to it and used chmod 0755 on all six files then tried to run it and this is what I get.
Code:
[email protected]:/storage/emulated/legacy/folder # parted
sh: parted: not found
127|[email protected]:/storage/emulated/legacy/folder # ls
e2fsck
mke2fs
parted
resize2fs
sdparted
tune2fs
... how can you NOT find that?

Depending on how your PATH env var is set, the current directory might or might not be being searched for program load(s). So indicating the current directory explicitly with a leading "./" such as
$ ./parted
will certainly work (if a read & execute bit set on file, and the filesystem is not mounted -noexec ) .
But...
...if those files are dynamically linked rather than statically linked, and the appropriate link-libraries they reference come up missing during run-time linking it is possible to still see a "not found" message. Sort of a red-herring error message, but there you go.
I just looked in TWRP's /sbin (ramdisk) just now. Don't see parted in there.
[Edit] I do see the string "fdisk" inside the busybox executable though! - maybe boot into recovery and see what
busybox fdisk /dev/block/sda
gets you? (I suppose result depends on whether or not TWRP kernel plumbs the device into place.)
Perhaps the quickest solution is to simply use a PC and media reader to do the partitioning from a PC instead of the N7. You might even want to boot a "Live CD" version of Linux to get at the tools you need. (BTW, I think that Ubuntu's Live CD mounts a fuse FS over the top of the RO DVD/CD, so you can even download and install packages as needed).
I managed to get everything to work by doing this:
1. Using this app https://play.google.com/store/apps/details?id=com.beansoft.mount_system&hl=en I remounted /system as RW
2. Using the CyanogenMod File Manager I copied the parted file to /system/bin (from the root of the SD card)
3. Then using the File Manager still, go to the Properties of the parted file and go to Permissions and under R, W, and X put a check mark in the three boxes bellow each. (I don't know which ones it needs permissions for so I just give it permissions to everything, kinda frowned upon to do but I trust this program so...)
By doing this you can completely stay out of command line, but at the same time you're installing a command line program so you shouldn't be afraid of the command line in the first place. Lol.
Note: After this you can go to a terminal window and type su to get root access then type
Code:
parted /dev/block/sda
you will of opened your external memory card, now use parted as you would normally.
Lets start by saying i did not have anything to do with the making of this I'm just re-posting for the people who had it tough like me.
What i did was use Ouya Tool Box to root, su, busy box etc.
Installed ES file explorer, ES Task Man

This should be able to be done on any Ouya since they are all rooted, but you have to have root access.
This fix will give you full access to your USB flash drive as a "sd card". It will even be listed in the 'storage settings' and will be visible from Windows under the "Ouya Console" drive that pops up when it is connected.
First you must mount /system read-write. You can either use adb shell, or sideload "Android Terminal emulator" if you have a keyboard:
adb shell
mount -o remount,rw /system
After this you need to edit the file /system/etc/vold.fstab. There will be two lines at the end:
Change this:
dev_mount sdcard /storage/sdcard1 auto /devices/platform/sdhci-tegra.0/mmc_host/mmc2
dev_mount usbdrive /mnt/usbdrive auto /devices/platform/tegra-ehci.2/usb2
to this:
#dev_mount sdcard /storage/sdcard1 auto /devices/platform/sdhci-tegra.0/mmc_host/mmc2
dev_mount usbdrive /storage/sdcard1 auto /devices/platform/tegra-ehci.2/usb2
How does this work? Well, the first line, we comment out. It refers to a storage device on the tegra that is connected to nothing at all, basically the on chip SD/MMC that we have no slot to stick said MMC card to. The second line, we tell vold to detect the USB stick we boot with or insert, as a SD card. Really any storage device can be here (try it with a hard disk!) but in our case we want the first USB storage device to be here. In theory this hotplugs well, as I have tested removing it and reinserting it locally. It will look like an SD card to the Ouya. I am going to test moving an app to it and running it in a moment.
Really this file hack should not be necessary, the proper way to do this is editing init.rc and changing
export SECONDARY_STORAGE /storage/sdcard1
to
export SECONDARY_STORAGE /mnt/usbdrive
However /init.rc cannot be edited without modifying the bootloader, and since Ouya has no button to go into recovery yet, I am not willing to risk or even talk about editing /init.rc in your boot image.
Anyway, if anyone else wants to try this and confirm it works for them i'll watch this thread for a bit. Maybe the Ouya devs can incorporate it into a build, or just set SECONDARY_STORAGE in /init.rc right.
However the fix I just gave is easier because if you change SECONDARY_STORAGE you're gonna have to change every reference to /storage/sdcard1 down the line.

FYI, they might have included it in an upgraded, since my usb cards gets mounted to: /mnt/usbdrive, but there also seams to be a symbolic link in the root folder, which is quite nice.

sadly I I did not like the way that was working. So I found this method. It shows you in the storage menu that you have something mounted (SD it says) It feels more natural and I don't know if its a placebo effect but things are faster and xfering faster

As such, I haven't been able to see if this fix works, and my 32GB USB drive shows up as an empty, blank sdcard1 when I plug it in.
!!!! please don't use this method now. I tried it a few days ago and it did not work after a Ouya Update. sorry. i should have mentioned.

no it should be auto mounting as /mnt/usbdrive
install ES file manager after your Root and get SuperUser.
i use the on ouya root.

ES definitely shows the USB drive as a USB drive, which as a result, has made ePSXe (installed from the Play Store) able to find my PSX ROMs. RetroArch still says sdcard0 and sdcard1, and on sdcard1 (the USB drive), it shows as empty.
What to do?

i dont know what else to tell you homie. when my ouya turns on i look to see if the LED indicator is blinking "access" behaviour. If it doesn't it didn't read it. If you don't have a LED sorry. check /mnt/usbdrive thats what i use now. all my emus etc. can see it.

It's definitely being read. Has a little blinking LED. If ES and ePSXe are reading it, I know it's working. Just gotta figure out why RetroArch won't read it, or find some other emulators that will.
What emulators are you using?
If you got the PSX emulator to read your Roms already then it sounds like it is the Retroarch messing up. I would recommend loading individual emulators anyways.
FAT (the old DOS-based file system) is a bad idea.
It's ugly, doesn't mix well with Linux and saves timestamps in local time.
Moreover, the Nook has problems with FAT, randomly changing timestamps a number of hours.
Certainly at daylight savings time transitions everything changes.
If you use timestamps as an indication for syncing files from a host, this is a problem.
UMS (USB Mass Storage) is a bad idea.
It takes a happily mounted volume from an OS, and hands it in a raw block view to a remote system.
Outside of using noogie for full physical backups or initial partitioning and formatting there is no need for UMS.
The last need of UMS was the Adobe Digital Editions which was discussed and obviated in this thread
Finally, there are some devices and occasions where you'd want to hot swap SD cards.
A camera taking megapixels shots might have a need for swapping SD cards.
Our Nooks use SD cards more as permanent expansion units.
Get a 32 GB card, stick it in and never take it out.
Then we wouldn't need vold (the volume daemon).
In another thread I posted a modified vold so that the SD card could be ext3 formatted.
To my mind, the cleanest solution to all this is to:
Format the SD card with ext3
Mount the SD card in init.rc inside the uRamdisk
Disable UMS
Disable vold
Right now I'm running into problems mounting the SD card inside init.rc
Code:
mount ext3 /dev/block/mmcblk1p1 /sdcard wait nosuid nodev noatime nodiratime
chown system sdcard_rw /sdcard
chmod 0777 /sdcard
init has not very useful error reporting, it returns an error of -1 for any condition.
I was trying to build init that could tell me something more.
This is a work in progress.
(If we get rid of vold, we'll have to strip the Android MountWatcher so that it doesn't flail.)
I found out what the problem with doing a normal mount in init.rc was.
The system had not found /dev/block/mmcblk1p1 yet.
I'm still working on this.
For now I have a oneshot service that mounts /sdcard.
It uses a little executable that waits until /dev/block/mmcblk1p1 appears.
I disabled vold.
I would have liked to be able to mount the SD card inside init.rc,
but apparently /dev/block/mmcblk1p1 has not appeared by then.
You need to have a service do the job, a few seconds later.
Yes, you could probably write a little script, but I'd rather write a little Linux program.
I'm still wondering if there is an easier solution to mount inside init.rc
People use their Nooks in such different way.
I would really like to know what exactly people are interested in this thread.
There is a poll at the top to fill in, please.
Pieces of the pie ready to go now:
mke2fs
tune2fs -j
Mods to init.rc - disable vold, enable mntsdcard
mntsdcard - a Linux program
Patches to MountService to disable it.
Is anybody interested in trying this?
Well, if you want to give it a go, here's how.
Black = commands to the Nook shell over ADB
Blue = commands to the Windows shell
Convert your SD card to ext 3
Backup the data on your SD card (or just let it all get deleted).
You can use adbsync.exe if you like:
Code:
[color=blue]mkdir sdcard[/color]
[color=blue]adbsync /hscu /s C:\sdcard sdcard[/color]
Then you can re-partition the SD card.
Code:
umount /sdcard
busybox fdisk -H 255 -S 63 /dev/block/mmcblk1
Do the commands to delete (D) old partitions, create a new (N) primary partition.
Then write (W).
Then format the SD card in ext2, upgrade to ext3 and check the mount.
Code:
mke2fs /dev/block/mmcblk1p1
tune2fs -j /dev/block/mmcblk1p1
mount -t ext3 /dev/block/mmcblk1p1 /sdcard
Install mntsdcard
Copy over mntsdcard:
Code:
mount -o rw,remount /dev/block/mmcblk0p5 /system
[color=blue]adb push mntsdcard /system/bin[/color]
chmod 755 /system/bin/mntsdcard
Get uRamdisk and extract init.rc:
Code:
mount -o rw,remount rootfs /
mkdir /boot
mount -t vfat /dev/block/mmcblk0p1 /boot
[color=blue]adb pull /boot/uRamdisk[/color]
[color=blue]bootutil /x /v uRamdisk init.rc[/color]
Add in a mount for media (we'll leave it FAT for now):
Code:
mount ext2 /dev/block/mmcblk0p5 /system
mount ext2 /dev/block/mmcblk0p5 /system ro remount
[b] mount vfat /dev/block/mmcblk0p6 /media sync noatime nodiratime uid=1000,gid=1000[/b]
Comment the old vold stuff out:
Code:
#service vold /system/bin/vold
# socket vold stream 0660 root mount
Add in the mntsdcard stuff at the end of init.rc:
Code:
service mntsdcard /system/bin/mntsdcard
oneshot
Replace init.rc and push the uRamdisk back:
Code:
[color=blue]bootutil /r /v uRamdisk init.rc
adb push uRamdisk /boot[/color]
reboot
If there are any problems, look in /data/mntsdcard.log
Restore your SD card
Code:
[color=blue]adbsync /ascu /s C:\sdcard sdcard[/color]
Wow, this seems like a lot of stuff to do! :cyclops:
Thanks so much for all this great dev work, Renate!
:good:
BUT!
Will this definitely make noogie not function correctly? (I make new backups with it, like, once every week and a half, so that would definitely stop me from trying this)?
What will this do to the regular USB mounting onto a PC?
What will this do to mounting USB devices on the Nook using host mode?
And, finally: Will this mean I can't ever remove my SD card to use for something else temporarily (or to write a Nook-bootable image to it for miscellaneous reasons)?
Thanks,
3N

That isn't correct. Linux has had support for FAT file systems very early on
and Linux support is quite stable. Saving timestamps in local time should not be a problem.
These mods look like it would make it non-trivial to side load content (unless you are using Linux for a main PC) for no reason.

It's a problem twice a year when daylight savings time makes all your file times shift one hour.
Also, try moving timezones on your device.

Mmm, not really. I have a Windows desktop and I use ADB push/pull and my adbsync utility.
Moreover, I can easily sync all my Android devices before going out the door.

But if we wanted to transfer files without WiFi, ADB wouldn't be available, and so how would we sideload our files w/out ADB?
I agree ADB file transfer is more fun - heck, you can use an FTP Server app and manage your whole filesystem in the comfort of Windows Explorer! But without WiFi...

ADB is something a little advanced for me at this point. But regardless of if you want to use it or not,
It is still very handy to be able to just copy files on and off the device just by moving the SD card or mounting by USB
I suggest that the OP adds a note for less experienced users so they know that you lose those capabilities if you do these mods.

I entirely agree. Although ADB is fantastic and I absolutely love it, it's good to still have the USB mounting option instead.
The post you replied to was actually pointed toward Renate, so yeah.

Good luck. My experience is that much depends on the model you have and the rooting method used. I have an original NST on which ADB over USB works without an issue. I also have a NST with Glowlight (rooted with NookManager) that I can't seem to get it working on. (I can't remember how I rooted the NST, it was a couple of years ago.)

AH! Good to know! I thought that I was just being a dumbo not being able to get ADB USB working (I have an NSTG rooted w/NookManager), but now that I hear that you're having problems, too, maybe I won't worry so much!
Getting ADB to work should be easy, especially if you have a few devices and can see if the problem is with the device or the host.
On Windows getting ADB over USBcan be a pain. There are a few roadblocks:
Make sure that your device is using USB and not WiFi for ADB. The option is set in init.rc in uRamdisk. Use bootutil.exe to check/edit.
Getting the WinUSB driver loaded. Use the driver package from here: http://forum.xda-developers.com/showthread.php?p=49665945#post49665945
Getting ADB to recognize B&N devices. The newer adb.exe has the VID for B&N built in. The older adb.exe required fiddling with adb_usb.ini

Yep, already seen these in previous posts. Modifying uRamdisk doesn't seem to work, as I can still use wireless ADB with or without the mentioned changes. Already edited adb_usb.ini to include B&N. And, I think, already got the WinUSB driver. I'll check that, though.
As stated many times, if you can connect to ADB over WiFi then you can not connect to ADB over USB.

Yes, I know that, too. The problem, as stated, is that I always can connect over WiFi, and never USB!

Are you modifying init.rc inside uRamdisk? (Not the one that appears in the root after you have booted.)
What about default.prop in uRamdisk?
Do you see a 5555 anywhere?
Are you using some amazing-super-duper-ADB-instant-turn-on-offer-application?
Well, don't.

Answer 1: Yes, I most definitely am. In fact, I am using your bootutil.exe program to do it.
Answer 2: Yes, I also edited that to match what you wrote in the Minimal rooting - back to basics thread.
Answer 3: Yes, in the line of code
Code:
setprop service.adb.tcp.port 5555
It doesn't matter if I comment it out, it still connects wirelessly.
Answer 4: Yes, I am. But if I don't use one, then how will I turn ADB on or off?
