Superuser.apk

I have successfully installed a Superuser.apk but it does not seem to be working properly. Titanium reports that Su does not elevate to root.
I have debugging enabled and I have connected through adb shell but nothing seems to work.
Anyone have any success? If so, which version did you use?
Here is my method
I download 2nd link from here :
http://forum.xda-developers.com/showthread.php?t=682828
After unzip (E:\Android\ROOT\step4\ directory for my example) :
adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
adb push E:\Android\ROOT\step4\system\bin\su /system/bin/su
adb shell chmod 6777 /system/bin/su
adb install E:\Android\ROOT\step4\system\app\Superuser.apk
adb reboot
trying this now, will report

I am trying to do same thing with mediascape , but I get error
"Failure [INSTALL_FAILED_DEXOPT]", I am reading on google that its something related to the .odex file, how can I install/or whatever I have to do in order to be able to put mediascape back.
I know I just could restore and than root again and remove rm command for mediascape from ch file, but I am trying to remove more branding apps of telenor firmware and flash and root again with clean system.
PS: Messing with my phone as I don't have any knowledge in programming...just google.
Thx
Hi
You can try to do this :
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
cd /system/app
cp /sdcard/apps/mediascape* .
cp /sdcard/apps/MediascapePluginManager* .
reboot

restore mediascape (from step4 folder)
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*

I got mediascape back as I did't find better media explorer.
One thing can anyone explain what this lines of code mean(Jerpelea's mediascape restore), each separate if u can, I am trying to understand. As I said I am no programmer but I like to learn.
Thanks.
I've tried doing this 4 times... and it's not working ^^;;
Is it missing a step? Or is this all that I need to do?
I get no errors when doing it yet the program isn't working a shown in the screens realunited... ^^;
taye look into the second post of the guide thread -- it has all the info necessary, else: poke me on irc

You'd better typing it in terminal no in cmd
need root and type in terminal
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
cat /sdcard/flash_image > /system/bin/flash_image
chmod 755 /system/bin/flash_image
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
flash_image recovery /sdcard/recovery-RA-GNM-thunderg-1.1.0.img
reboot recovery
It will help you

[Q] adb question

Hi,
I have just installed wolfs 2.3 with hotfix and am having trouble with adb commands
I have tried pushing files to /data/data and I get this error
Code:
failed to copy 'name of file here' to 'path here' : Permission denied
However, if i boot into recovery and manually mount data it works.
My question is
what is the code to mount the data partition from adb?
I know
Code:
adb remount
mounts the system partition but i need the data partition mounted.
I have never ran into this before, all my adb commands worked whilst the phone was turned on...
any help please.
More issues
Code:
adb remount
does not work....permission denied
Also, using apk manager I cannot push sytem files to /system/app
This is quite irritating
The correct command is:
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
Code:
adb shell
su
mount -o remount rw /system
works for me.

Edit your first post, LIST STEPS of how you unlocked your BL

4. type "moto-fastboot.exe reboot"

(urgent) How to give write permission for system using terminal emulator?

What the command?
I need it quick please.
First you need root acces on your phone.
Then type this in your terminal:
Code:
su
mount -o rw,remount,rw /system
