How to root your LG GT540

[Guest r00tk1t]

Hi,

LG has patched the root method in the OP during some of the firmware updates. Right now, if you can't find "Enable Root Permission" or am having trouble installing the superuser app, you should give Universal Androot a try.

Universal Androot don't work on 2.1 ROM :lol: Searching any working methods for this ROM...

That post was made before 2.1 came out. But yeah, someone find a method for 2.1!

Hi,

LG has patched the root method in the OP during some of the firmware updates. Right now, if you can't find "Enable Root Permission" or am having trouble installing the superuser app, you should give Universal Androot a try. It roots your phone as well as install the superuser app.

A Superuser app grants apps permission to access the phone's root. Apps that have been granted permission are said to be in the whitelist, I think.

You don't really need to have to use AndroidSDK, if you just want to root your GT540 phone.

If you can't connect your phone to the computer, you most likely don't have the drivers installed. Get LG PC Suite IV from somewhere since the Official Site doesn't really give you a download link, you'll have to google it.

Hey,

thanks for the answer.

i got all ready the LG software, and i can connect to my pc too. thats not the problem :lol:

in the first post at this thread, paul says we would see the root status via ADB. i read at wikipedia whats "ADB" could be ( B) ), and wiki says i need the SDK base for ADB. well, however.

i will try the software u wrote and give u feedback.

second: the root status should be enabled. after i type the password i have permission to change the user and root status. after i check "Enable Root Permission", i'll get the "ok" message for password accepted, but when i reboot my phone...well... its easily gone.

thanks and best regards

On 4pda.ru get the root on 2.1 !

[Guest wwenigma]

i stucked on "waiting 4 device" with ADB... win7 x64... :/

mod: solved, start phone in fastboot mode, start image uploading with fastboot.exe THEN connect phone to pc. :lol:

I have successfully managed to root the GT540 , and seems superuser does not need to install apps that require root access (maybe this is security bug of this method , but does not need to modify the original rom like russian guys did). I only tried vnc server which works fine .

I will do a guide how to root the phone and create a zip which contains the neccesseary files (adb,rageagainstthecage, busybox,su).

adb push rageagainstthecage-arm5.bin /data/local/tmp/rageagainstthecage

adb push su /data/local/tmp/

adb push busybox /data/local/tmp/

adb shell

$chmod 4755 /data/local/tmp/rageagainstthecage

$chmod 4755 /data/local/tmp/busybox

$ cd /data/local/tmp

$ ./rageagainstthecage

adb shell

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 / (maybe this not neccesseary)

# cd /data/local/tmp

# ./busybox cp su /system/bin

# ./busybox cp busybox /system/bin

# cd /system/bin

#chmod 4755 su

#chmod 4755 busybox

#su

#id

the id should be 0 and gid should be 0

#busybox --install /system/bin

#cd /system/xbin

#ln -s /system/bin/su su

#cd /system/bin

#cat sh > su

#reboot

after the phone reboot

adb shell

$su

#

Now you should be able to install any app that require root.

I left out to push the Superuser.apk to /system/app beacuse the app2sd script or the vnc server install does not opened it but they works .

why ?

[Guest joestone]

OK !

I have made a modified version according to the suggestions from forum members . The busybox left out , and now it is using the superuser app .You need the uploaded zip file from the original post .

You should wait for this part until the phone fully up , because when you type su the superuser app should be come up on phone's screen and you need to allow it .

Thanks for the cooperation to everybody !

Do I just have to put my phone on debug mode then connect it on my pc then type the commands posted above on command prompt? What do I need aside from rootgt540v20b.zip?

Yes the debug mode must be on access the phone via adb .

The zip contains all you need , not needed to install the sdk.

It contains the adb , the superuser application and the su .

[Guest bloodlust8]

thanks.. will try this later..

---------------------------------

Access is denied.

Any way to correct this? Using Windows 7 Ultimate 64 bit.

nevermind.. already on the last part.. permission denied..

Edited October 1, 2010 by bloodlust8

[Guest joestone]

at the very beginning..

You should run the command prompt in administrator mode .Right click to it and selet run as administrator.

I do this process on win7 pro 32bit.

[Guest bloodlust8]

Im already on this part:

C:\rootgt540v20b>adb shell

$ su

su (after this part it says Permission denied)

# id

id

uid=0(root) gid=0(root)

[Guest bloodlust8]

done.. thanks a lot.. will test Titanium Backup..

----------------------------------------------------------

Titanium Backup works even the Chuck Norris Mode..

backing up messages works but restoring it does not, can somebody confirm this? I guess I have to mail the developer..

You got this message after reboot or when ? Try to restart the phone and start from the begining.

i got this on the first step.. do i have to put the phone to a 'special' mode,like recovery or debug... and how can i do that?

The phone should be work in normal mode.

The phone should be in usb debugging mode , storage mode must be off .

The debugging mode is in the settings, applications, development menu .
