Getting root

Hi!
First post, but I've got a few things nailed down right through searching the forums and various guides and wiki's.
I've managed to install Google ION with firmware v1.5
I've SIM-unlocked the phone, using another carrier works splendid.
The Kernel version i'm using is 2.6.25.00894-g83efb08-dirty
[email protected]
My build number is CRB43
What I'm trying to accomplish here is getting root on the filesystem. I've tried various methods, guides and forum conversation tips but I can't make /system anything else than ro (Read-only).
I have installed Better Terminal from Market.
su and telnetd works perfect, I can connect to the phone using telnet. I'm using telnet to connect to the device, by forwarding ports through ADB.
I have tried using ADB shell to get root as well as telnet.
What I am trying to do is replace my current keymapping from an English one to an edited, åäö-capable one, because it's damn tricky trying to type these characters on the hardware keyboard. I haven't even found a way of typing åäö without replacing the keymap because of very little information about how the keyboard _is_ mapped using Android on the Kaiser.
Please advice wither on how to be able to type åäö characters without having to modify the keymap or give me a heads-up on how I'm supposed to get root on this filesystem, using commands such as;
# mount -o rw,remount /dev/block/mtdblock3 /system
does not give me an error but nothing else is returned either so I can't verify that the command actually executed or did anything to the system. I can however verify that the /system is still ro and still as a cramfs type no matter how I attack this.
Here's my situation on my mounts;
Code:
rootfs on / type rootfs (rw)

A2SD Error?

Been searching tons of forums for answer, seems like no ones problem is quite like mine though, so...Time to ask you guys
I'm running newest RA-Amon Recovery
I'm running Damage Control 2.09.01
I have been TRYING to get A2SD working correctly for a few days now with no luck....
I've formatted my card, wiped my phone, partitioned SD as follows:
Swap 32mb
Ext 2 512mb (Changed to Ext 3)
Fat32 Remainder
Not sure if it matters, but I have a 32GB SD card...
When I run busybox df -h this is what I get:
C:\AndroidSDK\tools>adb shell

Also, if I try to install a program from Market, it downloads fine, but Fails to Install due to Insufficient Storage
If anyone has any ideas or would like me to try something else, I'm all ears. Phone starting to frustrate me

Don't know if this will work, but try this:
Go into an adb shell. Type this:
cd /data/data/com.android.vending/cache
rm -f *
reboot
This will clear the market cache and reboot your phone.
Let me know if that works.

[Q] Read-Only internal storage?

Hi All,
(I've read tons of Threads here, but not yet found a solution).
My Galaxy Tab 10.1 is useless right now as it cannot write to internal storage.
Lots of apps crashing on use and doing a factory reset from the recovery menu does not help (Tablet is in exact same state aon reboot).
So, I've been using adb
Code:
C:\Program Files (x86)\Android\android-sdk\platform-tools>adb remount
remount failed: Operation not permitted
Here's the mount information from shell
Code:
[email protected]:/mnt/asec $ mount
mount
rootfs / rootfs ro,relatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
debugfs /sys/kernel/debug debugfs rw,relatime 0 0
none /acct cgroup rw,relatime,cpuacct 0 0
tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0
/dev/block/mmcblk0p4 /system ext4 ro,relatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p5 /cache ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p8 /data ext4 ro,nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc,discard 0 0
/dev/block/mmcblk0p1 /efs ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0
/dev/fuse /mnt/sdcard fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0
So, I've tried to mount manually from adb shell:
Code:
[email protected]:/ $ mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mount: Operation not permitted
[email protected]:/ $
[email protected]:/ $ mount -o remount,rw -t rfs /dev/block/stl9 /system
mount -o remount,rw -t rfs /dev/block/stl9 /system
mount: Operation not permitted
But, I have no SU command:
Code:
[email protected]:/ $ su
su
/system/bin/sh: su: not found
I've got the su binary from downloading off this forum, but I cannot copy that up either (even to seemingly writable mount points)
Code:
C:\Program Files (x86)\Android\android-sdk\platform-tools>adb push su /cache
failed to copy 'su' to '/cache/su': Permission denied
Any hints to what I can do now?

Hey, this forum is for Samsung Galaxy Tab 7.
Here is link for SGT 10.1
http://forum.xda-developers.com/forumdisplay.php?f=1050
But looks like your device is not yet rooted correctly.
The easiest thing is to find pre-rooted kernel and flash them via odin.

Thanks for the reply, yappoe!
I was following a guide I found linked on a forum to get the Tablet Restocked to factory settings.
However, when I try to write via Odin, I get an error message on the tablet in Red
Code:
Bct_sync_Odin: Error to NvBuBctUpdate![err:0x140005]
DownloadPartition_Odin: Error to Bct_sync_Odin![err:0x140005]
Tegra_Nand_Write: Error to DownloadPartition![err:0x140005]
Obviously a write error, presumably as the File system is in Read-Only mode ?
Ro

Yes, because permission is not set correctly. You need root access to do that.
I really don't know much about G-Tab 10.1, and I don't know what you were trying to do or are trying to do.
But if you are trying to go back to stock firmware, you can follow this steps.. it works on most Samsung. (Note: Unless you are moving from Honeycomb to ICS or vice versa, you do NOT need to re-partition).
you can download any official firmware at http://fus.nanzen.se/
1. Download Fus Check Downloader 2.1 and downloaded a Firmware for your region. It will automatically decode the .enc2 file to.zip file
(or find your firmware at sammobile.com, you can skip step 2).
2. Extract the .zip file generated from decoding file to a folder and I got
tar.md 5 file.
3. Start Odin - put the .md5 to PDA and leave everything else as is.
4. Go to download mode on the G-tab
and click start. It takes about 6 to 7 minutes to do the flashing.
Can't guarentee if it would work, but good luck.
Once you get it work with STOCK, go to the Galaxy Tab 10.1 forum
and find the instruction there to ROOT
http://forum.xda-developers.com/forumdisplay.php?f=1050

Thanks yappoe,
That is a nice tool for firmware downloading.
Unfortunately I get the exact same error immediately when trying to write to the tablet via Odin.
Code:
Bct_sync_Odin: Error to NvBuBctUpdate![err:0x140005]
DownloadPartition_Odin: Error to Bct_sync_Odin![err:0x140005]
Tegra_Nand_Write: Error to DownloadPartition![err:0x140005]
I think I have a sort of chicken and egg situation where I my problem is my drive is mounted in read-only mode and I cannot change it without rooting/executing su

same situation
I have the same situation but with my omnia 2.
suddenly, the internal storage became read-only.
I have tried flashing the ROM and unchecking "preserve device contents".
I have tried spyware, malware, antivirus from PC via usb mode.
I have tried low-level format.
I have tried hard reset.
I have tried below cabs.

nueStorageManager-v1.1
Til now, i still have the problem.
Im using a micro sd instead.
Im planning on opening my phone and removing the internal memory chip instead lol.

I did open up my tablet.
The internal memory is part of a single mainboard.
(I think its the same in almost every device)
Looking into getting a replacement mainboard now.

It's possible to use an external SD card as the internal storage. This won't fix the internal storage, but your Tab will work again. See this thread.

Cheers for the pointer, but the Galaxy Tab 10.1 doesn't have a place for an SD / micro SD card addition.

Ah. But you asked in the wrong forum.

The mainboard cannot have components removed/added ... You have to replace the entire mainboard.

[Q] - Is my SGS broken ? Disk error ?

From the console I see this:
Code:
# mount | grep ro,
rootfs on / type rootfs (ro,noatime,nodiratime)
/dev/block/stl9 on /system type rfs (ro,noatime,nodiratime,vfat,log_off,check=no,gid/uid/rwx,iocharset=utf8)
tmpfs on /mnt/sdcard/external_sd/.android_secure type tmpfs (ro,relatime,size=0k,mode=000)
/dev/block/dm-0 on /mnt/asec/com.dreamstep.wPicasaWeb-1 type vfat (ro,dirsync,nosuid,nodev,relatime,uid=1000,fmask=0222,dmask=0222,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro)
#
What does it mean the last line ? Why it is mounted in ro ? Maybe during the mount the system founds disk errors and force to mount it in read-only mode ?
How can I check the filesystem ?
Thanks!

[Help] Changing Around Mountpoints for sdcard and extSdCard?

Hey guys.
Some previous Samsung devices had no external storage at all but still mapped the biggest flash partition to /mnt/sdcard.
The Galaxy Tab 2 7.0 has a Micro SD card slot on it (one of the reasons I bought the thing!), but I guess for compatibility they still mount an internal flash storage partition to /sdcard. The actual micro SD card gets mounted to freaking /mnt/extSdCard.
Why does this matter?
Basically, tons of stuff in Android is setup to dump the large files to /sdcard by default. Things like games that require an extra download, the Camera app, etc. I've got a 32GB microSD card in there, and it makes me really frustrated that stuff won't just automatically use that.
So. What I'm looking to do is switch them around, so the internal fake flash partition ends up mounting to /mnt/extSdCard and the REAL microSD card mounts to /mnt/sdcard. That way my big huge card is where most data will end up automagically. Ultimately if I could just dump the internal "sdcard" partition and give that space to other parts of the system, that'd be sweet, but at this point I'm still kindof in la la land with Android, so I'll be happy just to get the mounts flipped around.
I do Linux stuff for work, and use a 5-disk file server at home running Ubuntu Server, so I approached this problem in a Linux way: why not mount via fstab??
Turns out Android doesn't actually directly have a /etc/fstab. Instead you've got /system/etc/vold.fstab.
From my brief research, this file appears to work pretty much the same way as fstab in Linux.
However, the stock one doesn't contain any mountpoint for the fake internal sdcard. vold.fstab seems to tell the vold executable what to do during boot-time.
My first problem: the vold.fstab file on my device doesn't contain any mount instructions for the /sdcard device.
Not a problem, I have SSH and WinSCP working, so I got a read on the mount points likeso:
Code:
127|[email protected]:/dev/block # cat /proc/mounts
rootfs / rootfs ro,noatime 0 0

OK. so the vold.fstab file contains:
Code:
## Vold 2.0 Generic fstab
## - San Mehat ([email protected])
##
#######################
## Regular device mount
##
## Format: dev_mount <label> <mount_point> <part> <sysfs_path1...>
## label - Label for the volume
## mount_point - Where the volume will be mounted
## part - Partition # (1 based), or 'auto' for first usable partition.
## <sysfs_path> - List of sysfs paths to source devices
######################
# external sdcard
dev_mount sdcard /mnt/extSdCard auto /devices/platform/omap/omap_hsmmc.0/mmc_host/mmc1
#usb host device
dev_mount usbdisk /mnt/usbdisk auto /devices/platform/omap/musb-omap2430/musb-hdrc/usb1
So, I have made a backup of my vold.fstab file, but I'm a little gun shy about making changes to it, particularly adding a new line for the "internal" sdcard. I know there are a couple of other ways to probably do this, like an init.d shell script that just executes the needed mount commands, and I'm honestly not sure if putting an entry for /mnt/sdcard into vold.fstab will override the mounts that are (I guess?) coming from the ramdisk init sequence. Any input, XDA devs?

Go for it :thumbup:

I have the same Problem on my Galaxy Tab2 7.0 WIFI (GT-P3110 8 GB). I found a temporary Soloution for me. The App that i use is LINK2SD. You should have two partitions on SD card and both should be primary.
The first FAT partition is your standard sdcard (mountetd on extSdCard). The second partition /data/sdext2 is used for application files and can be ext2, ext3, ext4 or FAT32. Here are more informations about it: http://rootzwiki.com/topic/24500-if...move-apps-to-sd-card/page__st__10#entry701146
In this thread are the same Question: http://forum.xda-developers.com/showthread.php?t=1679037

I think it will read the changes. For example on the htc rezound the firmware update for ics changed the mount points from what was used in gb.So in order to run a gb Rom on ics firmware and vice versa the Fix was swaping vstab. Figure as long as u only mess with the sd mounts internal and ext. It will still boot and u can swap file as needed for testing.

I'll try and figure it out.
Already found one thing: running the mount command with no switches will list all current mounts (can't believe I forgot that!).

I'm pretty sure the partitions listed are found at /dev/block/mmcblk0pX, so maybe that's what needs to be mounted. I've not been successful yet in mounting anything manually but I just found this stuff, so hopefully will have it soon.

Hey DivinityCycle,
This post and tool in the S3 forum might be useful to you as it does the exact same thing in the GS3.

If I recall correctly it needs a kernel with init.d support. But I think it will definitely help.

I have this in mine i didnt see it in yours
#storage_struct = series, "/mnt/sdcard/extStorages"
#storage_struct = parallel

Making progress, I was able to mount the "external" sdcard to my test mountpoint using:
mount -t vfat -o umask=0000 /dev/block/vold/179:25 /mnt/testing
So, that's part of the puzzle figured out. Now, just need to sort of out the internal "sdcard" device path and then I guess I can try throwing stuff into vold.fstab

OK I believe I have a solution will work, based on the init.d script inside the package Mattiadj made and Rostol linked me to (thanks!).
I modified his init.d script likeso:
Code:
sleep 2
mount -o remount,rw /
mkdir -p /data/internal_sd
mount -o bind /mnt/sdcard /data/internal_sd
mount -t vfat -o umask=0000 /dev/block/vold/179:25 /mnt/testing
mount -o bind /data/internal_sd /mnt/extSdCard
vold has to be used for external storage. The internal storage isn't very flexible, which is why that guy's script just binds it up during boot time rather than some other method of mounting it.
I have just run the commands in a terminal one by one and they all appear to do exactly what they "should", and I have verified that the result is the "real" sdcard being mounted to /mnt/sdcard, which ALSO makes it accessible at /sdcard (which I think is just a symlink). That's the default target for most apps, so after installing this init.d script I think everything should "just work".
Obviously you could adjust the mount point for the "internal" sdcard space as needed.
Working on the script and installation bit now.

mount -o bind /data/internal_sd /mnt/extSdCard
echo "Script done"
Basically I am logging the output to /data/local/tmp/sdcard.txt, so I can debug.
In that log, it gets as far as the first mount command, and then things go off the rails:
Code:
Script start
Sleeping 2 seconds
Now attempting to remount root filesystem RW
Make the internal_sd directory
Bind the internal sdcard to the new folder
mount: Invalid argument
Mount the real sdcard
mount: No such file or directory
Bind the internal_sd directory to the extSdCard mountpoint
Script done
What's messed up is, the same mount command (with the bind) works fine once the device is all the way booted up.
Its just during the "init" sequence that it has a problem. I have no idea why

We had a similar thing for my Droid x2. You my want to check out this thread http://forum.xda-developers.com/showthread.php?p=16875467 and contact the dev.

That guy did it via vold.fstab, which is interesting.
The relevant stuff:
Code:
# external sd card
dev_mount sdcard /mnt/sdcard:none:lun1 auto /devices/platform/tegra-sdhci.2/mmc_host/mmc2 /devices/platform/tegra-sdhci.2/mmc_host/mmc1
# internal eMMC
dev_mount sdcard_ext /mnt/sdcard-ext 18 /devices/platform/tegra-sdhci.3/mmc_host/mmc0
I am honestly not too sure what I'm looking at there, so I'm gonna try some stuff in vold.fstab next.

OK, I am too tired to keep messing around with this for tonight, so I am trying out a new method: I moved my init script over to /data and then used Script Manager to make it run as root as boot time.
This is obviously not a permanent fix, but should be OK for tonight.
Basically my big problem is I don't know the syntax for vold.fstab to mount the internal sdcard to a new mount point...

Ahh the joys of doing weird hacky stuff to your tablet... I pretty much gave up on the vold.fstab working in the short term, and instead just tried setting my init script up as just a regular "run at launch" script using Script Manager.
The version of my script that I posted had unforeseen consequences. For whatever reason, doing a "bind" of /mnt/sdcard like I was doing caused all sorts of things to stop working. Like, Script Manager was locking up, as was Root Explorer!
The best one was that when my alarm clock went to go off this morning it crashed, and I was late for work! LOL
Sooo yeah, that's pretty special. I had to use Terminal Emulator to fix my stuff on the bus on the way to work
I have revised my script and it now works perfectly with the caveat that I'm simply unmounting the internal "sdcard" partition and letting it sit there unused.
Code:
#!/system/bin/sh
LOG=/data/local/tmp/sdcard.txt
exec 3>&1 4>&2 >$LOG 2>&1
echo "Script start"
echo "Unmount internal sdcard"
umount /mnt/sdcard
echo "Mount the real sdcard"
mount -t vfat -o umask=0000 /dev/block/vold/179:25 /mnt/sdcard
echo "Script done"
I believe because of vold.fstab the microSD card still gets mounted to /mnt/extSdCard. My script puts it at /mnt/sdcard as well. This seems to work OK because then the few programs that are smart enough to access the card via /mnt/extSdCard still can get to it, but everything else that works on the regular sdcard also goes to the sdcard as well.
I have tested out the camera, music player, Root Explorer, Script Manager, etc. Everything I have tried works exactly as expected.
The next thing I'll need to test out is if this script can be used as an init.d script instead of needing Script Manager to set it up to run at boot.
I figure the only other things to do are:
1-figure out what's needed to be able to mount the internal "sdcard" partition to a different mount point
or
2-figure out how to delete the "sdcard" partition and then just give that extra space to one of the other flash partitions (probably /system?)

I really am hoping you get this figured out and it can be used by us common folk. (I'm no hacker) Lol :thumbup:

Wow, while working on my init.d script, I managed to make my system freeze at the bootup animation. I "unlocked" things by reflashing my ROM.
Good thing its a slow day at the office...

i really hope u can get this working, would love it
