Hi!
Short and simple:
I've used this guide to 'root' my HTC magic.
Concerning the guide, my phone is root'ed.
Output of adb shell id
Code:
uid=0(root) gid=0(root)
Now I want to use android-wifi-tether, but the app tells me I ain't got root.
Am I missing something?
Thanks for help,
xenator

Does the su-binary exist /system/bin/su?
You could type something like: "ls /system/bin/su" to check that.
If this binary does not exist execute following commands:
adb shell
cd /system/bin
cat sh > su
chmod 4755 su
... try again ...
Code:
# cat sh > su
cat sh > su
cannot create su: read-only file system
Seems like I've to re-mount with 'rw'?
I'm a linux guy, but I don't want to break anything on the phone
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Did the job.
Now it seems that my kernel is missing 'netfilter'.
How do I get a kernel with that option compiled?
And again I could help myself
See here.
Thanks for the help so far!

android-wifi-tether works just fine, but I'm not able to use my "normal" WLAN anymore.
Anytime I try to activate WLAN in the settings it says "WLAN could not be started".
Anyone can help?
Okay guys.. I successfully rooted my phone and I removed a bunch of apps and stuff. one of the apps that i removed was Mediascape. I couldn't find a better media player so i attempted to restore the app using this in cmd:
adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
adb shell dd if=/sdcard/apps/MediascapePluginManager.apk of=/system/app/MediascapePluginManager.apk
adb shell dd if=/sdcard/apps/MediascapePluginManager.odex of=/system/app/MediascapePluginManager.odex
adb shell chmod 644 /system/app/MediascapePluginManager*
adb shell dd if=/sdcard/apps/mediascape.apk of=/system/app/mediascape.apk
adb shell dd if=/sdcard/apps/mediascape.odex of=/system/app/mediascape.odex
adb shell chmod 644 /system/app/mediascape*
adb shell reboot
After my phone rebooted.
As it was starting back up, the sony ericsson logo appeared (and i could hear the phone connect to my computer) but then it would end up going to a black screen. And it has been stuck on that for 5 minutes. I can still enter commands, but other than that, I have no idea what is happening. Anyone willing to help me out?
I've also tried removing the app again, but no go
EDIT
NEVERMIND. I got it to work again....
sorry about this, I kind of had a panic attack haha
Hi,
I have rooted my Nexus one. I can do "'adb shell and then 'su' under the shell"
But on my MacOS Desktop, when I execute 'adb remount', it still said
$ adb remount
remount failed: Operation not permitted

Can anyone please help me resolve this?
Thank you.

Right at the top. Why does this have to be repeated on a daily basis?
Can you please move my thread to the right forum? I can't find a way to do it.
Anyhow, to answer you question... you "adb remount" is disabled in production releases... just rooting does not allow this.
You need a modified boot image where ro.secure=0 in default.props, instead of ro.secure=1. The ro.secure flag in the boot image indicates whether the root filesystem can be remounted as read/write... 0 indicated it can be... 1 indicated it cannot be.
If ro.secure=0, this is referred to as insecure boot.
Most custom ROMs have this by default... some rooted stock ROMs do not have this...
Will the Modified GRI40 (2.3.3 Gingerbread) ROM from this
http:// forum.xda-developers.com/showthread.php?t=968396
Does what I need? Thanks.
Or you can also use these commands to mount and unmount the system partition as writable:
Code:
mount -o remount,rw /dev/block/mtdblock3 /system
mount -o remount,ro /dev/block/mtdblock3 /system
Thank you. That seems to be an easier solution for me.
But after I did
$ adb shell
$ su
# mount -o remount,rw /dev/block/mtdblock3 /system

I go to another shell and i did
adb push sqlite3 /system
failed to copy 'sqlite3' to '/system/sqlite3': Read-only file system
$ adb push sqlite3 /system/bin
failed to copy 'sqlite3' to '/system/bin/sqlite3': Permission denied
Click to expand...

It still does not let me push 'sqlite3' to /system or /system/bin
That is what I need.
Thank you for any more pointers.

Don't try to combine adb commands with shell commands.
Copy/move/push the file to your sdcard first.
Then open a root shell, mount it as rw, then copy the file from your sdcard to the directory you want.
Thanks. but I get 'failed on '/sdcard/sqlite3' - Cross-device link'
$ su
# mount -o remount,rw /dev/block/mtdblock3 /system
# mv /sdcard/sqlite3 /system/
failed on '/sdcard/sqlite3' - Cross-device link

I get the 'sqlite3' from SuperOneClickv1.7-ShortFuse.zip.
Wholly crap, don't use the mv command! Bad idea!!! mv does not move the data, it moves the hardlink to the data! Thank your lucky stars mv wouldn't let you do it.
Use cp instead. cp will actually copy the data to where you're going.
Thank you. But I don't have 'cp' in my adb shell.
# cp
cp: not found
# /system/bin/cp
/system/bin/cp: not found

From here:
http://android-tricks.blogspot.com/2009/02/cp-on-android.html
I use 'cat' command to move to /system/bin
How do you have mv but not cp? Do you not have BusyBox installed?
No. I just need to search 'BusyBox' on Android market and install it? That is?

The cat command will work fine, no busybox needed: cat source_file > dest_file

Woah there partner. Cat shouldn't be used on binary files, only ascii files. While it might work fine, it is not the recommended practice and really should not be done.
OP, Yes, BusyBox can be installed from the market.

On standard Unix/Linux/etc. systems, cat works fine for binary files. It's only under DOS that cat or type shouldn't be used for binaries.
back in my ADB days.. itd say remount failed or w.e but i could still access my phone..
but i dont know.. ever since i switched to linux i stopped using ADB.. hahah
You can fix wifi channel 12-13 support by setting the wifi_country_code to EU.
You need a rooted device and sqlite3 to fix (attached).
Unpack the attached zip and run fix_wifichannel_EU.bat (Windows only)
or with linux:
Code:
adb shell
su
mount -o rw,remount /dev/block/mmcblk0p3 /system
exit
adb push bin\sqlite3 /system/bin
adb shell
su
chmod 6755 /system/bin/sqlite3
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "INSERT INTO secure (name, value) VALUES ('wifi_country_code', 'EU');"
reboot
Ohhhh it's good to see you here in the Iconia section!
I used to be a user of your great Desire Kernels/roms.
Hope to see some work from you soon.

so you got this tablet, richard =P Wonder when we will be able to start playing with custom rom =)
Btw, I notice that a huge amount of RAM is consumed and the maximum amount of RAM freed I have ever got is 440MB. Do you know what happened to the rest?

The rest of the ram is reserved for video on boot.
I thought so, but don't you think that is too much out of 1GB ram? I found the device is laggy if ram goes under 350MB. Hope modded kernel can help optimize ram.

Nicely done! It works. Yea it is good to see you here' meaning we have somebody who knows a thing or two about android development.

Fix worked!
For some strange reason adb remount command didn't worked and adb wasn't able to push sqlite3 file to /system/bin even after remounting /system rw from the device itself. I had to push it to sdcard and then move it to /system/bin.
By the way, channel 13 is working fine now.
Thx
Hi Richard,
It's good to see such a great dev interested in the A500 (I have a Desire). <vbg>
EDIT: I can confirm that this works!
I cannot remount /system, either via ADB nor via a shell (on the device itself). In both cases, I get...
Code:
mount -o rw,remount /dev/block/mmcblk0p3 /system
mount: Operation not permitted
[Edit: worked with a terminal, but forgot to SU first, and I was typing mmcblkop3, not mmcblk0p3 !!]
I tried to be clever (NB: I don't have a SD card installed):
Code:
adb shell mount -rw /dev/block/mmcblk0p3 /mnt/external_sd
Usage: mount [-r] [-w] [-o options] [-t type] device directory
That's the extent of my *nix skills...
Any ideas?

Try su before the mount command.
Edited the procedure in the first post so try that (should work now).

For the beginners (like me): I noticed that /system was set back to read-only on reboot...
Works brilliantly. Thanks.
thx - but I trust editing the build.prop in Root Explorer should also do the job for those who don't want to mess with adb and commands.
hi
can anyone tell me whats this fix for?
is it going to make wifi receiver even better?
thx..

yes,
add this line
ro.wifi.country=EU
and reboot.
i have this message:
'Unable to detect a device over adb'
I've connected my nexus S via usb cable, i've tryed with the usb usb storage on an off, and i get the same message.
I'm using windows / x64.

i've done that but i canot save the file i get the message that it's a read only file system.
how can i gain write access to that file??
Thanks the fix_wifichannel_EU.bat in the zip worked like a charm. Channel 13 now works on my Asus Eeepad Transformer purchased from the US as well.
any idea how to remount system via adb shell? I use
Code:
adb shell su -c "mount -o rw,remount -t ext4 /dev/block/mmcblk0p23 /system"
but every time I go to remove an apk it remounts as RO and I have to issue the command again.
If I type this it will remount in RW and remove the file but again it will relock the system after the command is complete.
Code:
adb shell su -c "mount -o rw,remount -t ext4 /dev/block/mmcblk0p23 /system" | adb shell su -c rm /system/app/ANTPlusPlugins.apk
