RA 1.6.2 SDcard woes.

Alright, So I'm trying to enable JIT on my phone, but I'm running into a problem where when I cd into /sdcard and try to ls, the directory shows as empty. Trying to cd into anything gives me this
Code:
/sbin/sh: cd: can't cd to /sdcard/dusted
My question is, what are the commands to mount my sdcard with -rw permissions?

try mount -a
or
try mount /sdcard/

mount -a returns
Code:
mount: mounting /dev/block/mmcblk0p2 on /system/sd failed: no such file or directory
mount /sdcard returns
Code:
mount: mounting /dev/block/mmcblk0p1 on /sdcard failed: device or resource busy

Then try:
Code:
mkdir /system/sd
mount -a

Code:
mkdir /system/sd
mkdir: canot create directory '/system/sd': File exists
Tried a different SDcard. Same problem.

Also, the JIT guide can be misleading. At first I thought it meant to do all of this while the phone is in recovery. Needless to say, that does not work.
I got the same results as you, so maybe that is the problem.
The phone needs to be fully booted.

whats happens when you do a 'adb remount'?

Code:
remount failed: invalid argument

Tried killing the adb server and restarting it. Still a no go.

Looks like the ext partition on the SD card is missing. Did you repartition adding both ext and swap?

I don't run a2sd

Then it's not going to mount /system/sd since that is a2sd.

I'm not trying to mount an ext partition. I'm trying to mount the sdcard itself.

Your errors above seem to indicate that the sd card is mounted. As to wether its readable is another matter. What do you get when your do a:
Code:
ls /sdcard
Have you tried rebooting into recovery?

Boot the phone into Android.
Open ADB and type mount.
Paste the results here.

mounting /system as rw?

this seems simple enough since we can do it with all other android devices that have root. but it isnt, apparently. because we're running with a stock bootloader/SPL/recovery/ROM, adb wont run with SU permissions. this means abd remount doesnt work.
also, we dont know what the directory is to mount from /dev (i.e. on the G1 it was /dev/block/mtdblock3) to get system to mount as rw.
my point in asking is that i'm trying to do something i'm sure a lot of other people would like as well. custom ringtones in /system/media/audio instead of on the SD card. why? because with the ringtones on the SD card, media scanner picks them up every time and lumps them in with the actual music you have on your sd card. ugh.
so, as soon as someone can figure this out, i'd love to know how to do it so I can push the ringtones or cp them using busybox. anyone who can help...well, lets get it going.

#
once you get there, just copy whatever you want wherever you want
something like
Code:
busybox cp /sdcard/sd/myfile.mp3 /system/media/audio/

mucho kudos! i have a feeling this will come in handy for a lot of people in the future.

Whoa... Do I need to do all this just to push a apk as system app?

No, all you need to do is:
adb shell (ony if you're using adb, if you're using terminal, skip this command)
su
busybox mount -o rw,remount /dev/block/stl9 /system
busybox cp /(location of the app here)/app.apk /system/app/
reboot
now, depending on where you have the app:
if its on the 14gb storage, it'll just be /sdcard/app.apk
if its on your actual sd card, it'll be /sdcard/sd/app.apk
all the stuff in the code post between # mount and the next # is what gets printed from the mount command. not actual commands.

adb remount doesn't work? I have been using it to delete stuff out of the /system/app directory... Maybe I am not getting what you are referring to.

Didn't mean to scare anyone with all that text, kusotare is right, the mount command shows what is currently mounted and where, its how I knew where to remount /system. Just used it as an example to teach as well

ahh, never mind, I see the issue now
So adb push to /system/* is never going to work until we get some custom roms then?

precisely t1n0m3n.

I used buysbox to try and re-install dlna.apk/odex and my phone boots normal, but wont every "wake up" after the Galaxy s screen, it just stays black, but the home keys are responsive? Did i screw something up?

Tried doing this. I have com.neevo.mobiledefense.apk in my adb folder so on my N1, I never actually had to type a location of the file but whether I use the location or not, I get file not found... Will my N1 mobiledefense system app *.zip work on this phone or no since the directories are different?

How to Run(Chroot) Linux(Ubuntu/Debian,etc.) in your Milestone 2

Chrooting Linux on Android is a very popular topic, and you can find many tutorials online. I am not going to post a detailed how to here.. but, I will explain the generalized steps for the process! If anyone have any questions or need help, feel free to ask!
Get Root Access on your phone
There are many ways to get root access; Easiest will be using z4root or SuperOneClick ! Rooting is mandatory because: You need to install Busybox; Need to mount file system, etc..​
Install SuperUser App from the Market
This application allows you to grant Root access to other applications (when needed). Depending on how you rooted your phone, superuser.apk may be already installed on your phone.​
Install Busybox App from the Market
Depending on how you rooted your phone, Busybox may be already installed on your phone. In any case install this app from the market and update your busybox to the latest version. Busybox is a set of commonly used linux commands, which are not available in android by default. Eg: cp, chroot, etc.​
Install Connectbot from Android market
Connect bot is a terminal client application for android. There are other alternatives but, I recommend Connectbot! Also Connectbot has SSH support, so if you are installing an SSH server on your Ubuntu, you can connect to it using connectbot and you may totally skip the VNC for GUI. Anyway, note that you need a terminal app to start the chroot daemon!​
Install AndroidVNCViewer from Android market
With androidVNCViewer we can get GUI access to our ubuntu! This App works so fine in my Milestone 2 with Ubuntu; It even supports mouse pointer!​
Download/build a Linux rootfs for your flavour of linux
Now, you need the Ubuntu/Debian/Other linux file system for your Phone's processor. Like most of the Android phones, Milestone 2 uses an ARM processor. And Ubuntu offers full support for ARM processors. It is so easy to build ubuntu for ARM(OMAP) platform using rootstock/bootstrap method. I used rootstock method for Ubuntu as explained here.
PS: For your first time, make sure you build, "Ubuntu Lucid" (just use the --seed/-s parameter of rootstock command. I was not able to use 11.04(Natty). Once you get Lucid to work, you can surely try yourself for the other versions! )​
Create a mountable .img file with a size suited for you
From rootstock, you will get a .tgz file! You will need to convert this to a mountable .img file.
In order to create an empty ubuntu.img file, use the followed command in your ubuntu-desktop's terminal; the last arguement (2048) specifies size of the Ubuntu rootfs (If you need much disk space when you are in ubuntu, use a large value here. Normally 2GB will be sufficient for you; even with GUI/VNC).
Code:
dd if=/dev/zero of=ubuntu.img bs=1MB count=0 seek=2048
Next, format our empty ubuntu.img with a suitable ext2/ext3/ext4 file system!
For Milestone 2, you should use ext3 (I think it does not support ext2). ext4 is supported only in Gingerbird+. So, you should use the appropriate command based on your mobile
Code:
mkfs.ext2 -F ubuntu.img
mkfs.ext3 -F ubuntu.img
mkfs.ext4 -F ubuntu.img
You can find out the suitable file system by opening Connectbot in your mobile and entering the followed command. In the output, look for words ext2/ext3/ext4!
Code:
su
mount
Once you format ubuntu.img with appropriate file system. We should temporarily mount the ubuntu.img in a somewhere and we should extract the armel-rootfs-xx.tgz to it. You can use these commands
Code:
sudo mount -o loop ubuntu.img /mnt
sudo tar -C /mnt -zxf armel-rootfs--xx.tgz
sudo umount /mnt
Download(and modify) or create a Shell script for automatically mounting your Chroot image
This is the most important part, we have to run a set of commands in our android shell to get into the ubuntu. To make things easier, we will write these command-sequence in a shell script, and whenever we need we simple call this script. Cool isn't it?. Basically this is what this script should do:
Code:
1. Check if there exists an ubuntu.img file as we specify in command line
2. Create a loop device with the ubuntu.img - ie. Make android(linux) believe that ubuntu.img is a mountable device.
3. Mount the newly created loop device to a folder. My script mounts the image to /data/local/chrootos
4. Set some environment variables in the shell
5. Mount the [I]devpts, proc, sysfs[/I] for the ubuntu!
6. Run the Chroot command. This command actually changes the root of file system to a new directory we specify. ie. we fake [B]/data/local/chrootos[/B] as the rootfs![B]/[/B]
Create a folder in your Phone's SD Card and copy one or more(If you want to choose between: Debian/Ubuntu/Puppy/etc) .img files and your shell script for booting linux into it.
Create a folder named .chroot in your SD Card. If you have a "." as the first character, this folder will be hidden in the Android File Browser. And will avoid you accidentally modifying these files.​
Get into your Phone's Shell through ConnectBot / USB-ADB / Terminal Emulator
Enter su in the terminal to get root access
Remount your Android filesystem to get write access to your phones
By default, the android file system is read only. So in order to write to the files sytem, we have to remount it with the following command.
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Copy your bootscript to /system/bin so that you can easily start your LinuxIf you have downloaded my bootscript, the file name will be bl - short for boot linux. So, once you copied you will have your shell script at /system/bin/bl. Once we copy the shell script to the bin directory, it will work as a shell command.​
Start your linux and customize it
If you have done everything correctly so far, you can now boot into your ubuntu.img with the following command. Note that you do not need to specify the full file name "ubuntu.img".
Code:
bl ubuntu
Start your linux and customize it
If Chroot was a success, you will see the ubuntu shell prompt. And then you can start installing more stuff, etc. [email protected]:​

Common Errors
The most common error will be when we are dealing with the "loop device". Because, according to the apps installed in your device, there may not be a free loop device available. If you are facing errors, feel free to ask me and I will try and help!​

Thanks, man! When I have time I'm gonna try it out.

Yeap, I faced the same error when I was doing it. If you notice the mount-list.txt, you can see that AngryBirds application is using /dev/block/dm-0 and /dev/block/dm-1. /dev/block/dm-2 is also in use.
You could try this:
Edit the script bl and replace /dev/block/loop1 in the script with /dev/block/dm-3. It might just do the trick.

Hi,
Which is your Mobile ?
Also -- Did you see reply #7, #8 on page 1 of this thread ?

There is another way to mount it without using the option -oloop
If you look into /dev/block you are going to find 8 loop devices, from loop0 to loop7. As android doesn't use that many loop devices it should be enough. You can mount it like this:
Code:
losetup /dev/block/loop7 /sdcard/ubuntu/ubuntu.img
mount -t ext3 /dev/block/loop7 /mnt/ubuntu
If your phone doesn't have a free loop device, you can create a new one, like this:
Code:
mknod /dev/block/loop99 b 7 99
losetup /dev/block/loop99 /sdcard/ubuntu/ubuntu.img
mount -t ext3 /dev/block/loop99 /mnt/ubuntu

The problem is you have apps installed to the sd card (and getting mount points busy), when it happens here I just open Titanium Backup and move External apps to internal.
No matter what I tried here, this script wouldn't work... So I used DebOnDroid app from defy forum, and when updated to GB. The app stopped working also, so I moved the ubuntu.img to /data/local/ and mounted from there, works like a charm!
This is the script I'm using /system/bin/buntu:
Code:
export mnt=/data/local/debian
export PATH=$PATH:/bin:/sbin:/usr/bin:/usr/sbin
export TERM=linux
export HOME=/root
export USER=root
echo "Linux Chrooter: Setup Networking"
sysctl -w net.ipv4.ip_forward=1
#necessary mount points
busybox mount -o loop $mnt/../debian.img $mnt
busybox mount -t devpts devpts $mnt/dev/pts
busybox mount -t sysfs sysfs $mnt/sys
busybox mount -t proc proc $mnt/proc
#extra mount points
busybox mount -o rw /system $mnt/mnt/s
busybox mount /data $mnt/mnt/d
busybox mount /sdcard $mnt/mnt/sd
echo "Linux Chrooter: Chroot!"
chroot $mnt /bin/bash
umount $mnt/sys
umount $mnt/proc
umount $mnt/dev/pts
umount $mnt/mnt/*
#somehow the commented lines didn't work...
#umount $mnt/mnt/d
#umount $mnt/mnt/s
umount $mnt
PS: when I copy a binary from ubuntu to /system/bin and chmod, it won't exec, why?

thank you very very very very very very very very very very very very very very very much!!!!
I made it!!!
oh yeah!~~~~

How is this different from using an app like linuxinstaller? Well, apart from doing it manually and the nerdy way of course?
Is it safer? I am intrigued by the possibility of having a working ubuntu in my pocket, but am wondering if I should go this way or try the app.
great guide though... i think this is the push i needed to finally try this.

Nice job! but i got this..

[Q] Thinkpad stuck semi-rooted (Help!) EDIT: SOLVED

Hey all. I have a 32 GB US TPT that was on 0075. I rooted it using djrbliss's method, and at some point managed to screw up my systemui.apk. I couldn't get it working again, so I attempted a factory reset. For some reason, that left Superuser in my list of apps, and Superuser will say that it has granted apps superuser permission, but whenever I try to do anything that would require root (like delete a system app), it doesn't work.
Also, I've tried to reinstall stock 0075 from a zip, but when I did that it said something about the update check failing on account of missing system apps.
So I'm kind of stuck. How do I fix this? I want to get the tablet fully re-rooted so I can install CWM and that 0075 no bloat nandroid backup.

I would first try to run the root script from djrbliss again.
Without root you are not able to restore the system-apps but they are mandatory for any update.

I forgot to mention that I did try re-running the root script. It gave me error messages saying it was unable to copy any of the stuff like superuser.apk.

Try the following. As you still can do su and promt changes to #.
Copy busybox to your device:
1. adb push busybox /data/local/tmp (busybox is located in djrbliss root script)
2. adb shell
3. su
4. cd /data/local/tmp
5. ls (to see if busybox is there)
6. busybox mount -o rw,remount /system
7. mount (to see if /system is mounted as RW)

Did all that, busybox is there, but I don't see /system at all in the list that comes up after mount. Did you mean sysfs? That one says rw.
PS: sorry for being generally clueless about this stuff. This is my first time doing anything much under the hood with Android.
Edit: another curious issue I just noticed: the tablet connects to my computer just fine via MTP, and shows up under adb devices, but when I select mount the SD card, the tablet immediately reboots. Also, it doesn't show up under adb devices if I don't select either, but that might be normal.

Please post output from mount.
It should look like this for system:
/dev/block/mmcblk0p3 /system ext4 rw,relatime,barrier=1,data=ordered 0 0

Oh, yeah, that's there, but it's listed as ro. Everything else the same as what you wrote.

Quiet hard to help without supplying output from shell.
What do you get after typing busybox mount -o rw,remount /system?

Looks ok and it accept the command without any errors.
Try this please and post output:
busybox mount -o remount,rw /system; mv system/bin/aba system/bin/aba_bak

Have you tried installing Titanium Backup and running it? I remember one time when I ran TB after running the YAREFTP script to get OTA2 rooted. Titanium Backup reported that SuperUser was installed but it's binaries were incorrect (or something to that effect) and offered to fix it for me. Root seemed fine after that.
Might be worth a try. Also, did you re-install superuser and then run it?

Mhm, so looks like it is not there and it will not prevent your /system to remount as rw.
I'm out of ideas.

I installed Titanium Backup just now, but it didn't give me any error message like that. I don't know how I'd go about reinstalling Superuser.

Damn, well thanks anyway. I appreciate you helping out.

Damn, I see the error now
As your are in /data/local/tmp mv system/bin/aba system/bin/aba_bak will not work.
So it should be:
busybox mount -o remount,rw /system; mv /system/bin/aba /system/bin/aba_bak

I think that one went through. It just accepted the command with no error message.

If it goes through it should be mounted as rw. Otherwise it is impossible to modify data on /system folder.
Check mount

So does that mean everything is working properly?

So far it looks ok. As it is mounted as RW you can install CWM recovery now.
Edit: Keep in mind to use correct CWM image for your TPT. It has to fit region and size.
Some people bricked the tablet while using the wrong image.

[Guide] [Root required] Allow Apps write access to SD card and USB Drive (Fire TV 2)

So, I ran in to some difficulty allowing apps saving to external storage.
As it turns out Google changed the default permissions to external storage in Android 4.4 (API 19)
I found a guide that solved this problem for me so thought it would be good to share on here
(All credits go to Android Revolution for the guide)
Procedure
Note: root required!
Start up your device normally and wait for the system to be fully loaded.
Open any files manager of your choice (Root Explorer, ES File Explorer, Total Commander) and make sure it runs with superuser permissions.
Mount your system partition as R/W (Read/Write) to perform any changes.
Navigate to the /system/etc/permissions/ folder and look for the platform.xml.
Copy and make a backup of the platform.xml file naming it platform.xml.bak
Open the original platform.xml file with any text editor on your device and search for the following line:
<permission name="android.permission.WRITE_EXTERNAL_STORAGE">
It should look like this:
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
</permission>
Now you need to add a 3rd GID (Group ID): <group gid="media_rw" /> and you need to make it looks exactly like this:
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>
Using ES File Explorer or any other Files Manager of your choice make sure that the platform.xml file has proper permissions:
Owner R-W | Group R | Others R (0644 rw-r--r--).
You can also use adb shell to set permissions with a chmod 0644 /system/etc/permissions/platform.xml command.
Reboot your device and enjoy!
In case of problems with OTA update just remove modified platform.xml and rename platform.xml.bak to its original name.
For those who just want my already modified, file click to download here
Confirm this works great on FTV2 and fixed my apps write problems

What apps need this? It's good info to have out there just looking for an example of what situations need it.

As examples,
Some emulators that save game saves to external storage (If configured that way)
UAE4ALL2 (Amiga Emulator) when using WHDLoad setup (Dos error if no write access to WHDLoad folder)
Titanium Backup to save backups to external storage location.
No doubt there are lots of other scenarios.

Hi,
just tried it but i'm not able to remount rw the system part.
I test it with ES File Explorer, RB, and over adb shell
mount -o remount,rw /system
Error: invalid argument
The root partition just works fine
What was your trick?
Regards

You need root, obviously.
Open ES File Explorer.
Scroll down to tools and select Root Explorer.
Grant SU permissions.
Now make /system R/W access
You can then amend / replace the file platform.xml file

Device is rooted
And yes, tried exact what you say but it did not work. The ES FE didn't even show up an error message. Any ideas?

Are you using ES File Explorer from Amazon Market?
No idea why it would not work.
Are you getting the Super User request when you click on Root Explorer in the tools menu?

If you can't remount system as rw just reboot and try again. When I used abdFire to install system tools I was unable to remount system until reboot.

Yes, i did recieved the request for su but as i already tried other root apps or commands during the last days, I'm almost sure that root works as design.
For ES FE the same, tried the Amazon Version and 2-3 apks which I deployed via sideload. Could you maybe post the output of that after a /system remount:
cat /proc/mounts
Would be helpful
@Ludacrisvp
Hm, actualy I rebootet several times but the reason for failing could be something which is coming up again in the background. I'll take a look in that

Good advise.
As a rule of thumb, I always do a clean reboot before I start to mess with stuff.

That's right. But in my case it makes no difference. I just reboot und connect to adb shell as soon as the device was recognize. No way

Installation was ok but the error is persistent
Maybe it was already too late. Busybox should be the first to install :silly:
OK,i guess i should reset, what do you think?

Does busybox add its own mount command?
Maybe try calling out the full path:
# /system/bin/mount -o remount,rw /system

damn, doesn't work
tried it also with the 2 argument method but same story
here's some output, maybe i'm blind and others can see it
did it via ssh to get a root shell. "adb root" comes up with no root in production system.

Not sure why @Fruchttiger00x0 is having so much trouble with it.
I just used ES File Explorer (root explorer) to mount r/w no issues.
Another option for you to try is via adbfire.
It has a simple 1 click button to make /system r/w
Other than that, maybe your root is not complete for some reason

I ran into the same problem mounting /system as rw. Banged my head for quite some time. I had rooted using the video tutorial by ultimate spy binns. So I rooted it again the same exact way and that solved the mount issue. So I was able to set platform.xml to fix the permissions but alas, my apps still cant write to external hdd.
