[How-To] Root LG Optimus T

[KSmithInNY]

Ok well now you're rooted so you can forget about that part. Try doing just this

adb push su /data/local/tmp/
adb push busybox /data/local/tmp/
adb shell
chmod 4755 /data/local/tmp/busybox
cd /data/local/tmp
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cd /data/local/tmp
./busybox cp su /system/bin
./busybox cp busybox /system/bin
cd /system/bin
chmod 4755 su
chmod 4755 busybox
busybox --install /system/bin
exit
exit


This is the same as above just minus the rageagainstthecage piece which simplifies things.

 

[KSmithInNY]

actually, you should already have SU so technically you could ...

adb push busybox /data/local/tmp/
adb shell
chmod 4755 /data/local/tmp/busybox
cd /data/local/tmp
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cd /data/local/tmp
./busybox cp busybox /system/bin
cd /system/bin
chmod 4755 busybox
busybox --install /system/bin
exit
exit

I'm still getting the no such file or directory errors.

 

[Kevin OQuinn]

and i just restarted my phone and computer and got back to the $, not the #. starting over. :sigh:

 

[KSmithInNY]

I'm still getting the no such file or directory errors.

Wait ... we need to take a step back and do some simple logical troubleshooting ...

1) Have you tried installing superuser from the market? What happened?
2) If it worked, have you tried running an app that requests root? What happened?

Yeah I must've read your mind. I just installed superuser and installed titanium backup. I hit problems and had it do the busybox thing. it requested su priveleges and was given them. i guess i was good the whole time and was freaking out about some error messages.

i will give your other request a try now.

@lightos I had that happen to me too. looks like you got it figured out because adb restarted.

Need help with something?

 

[Kevin OQuinn]

Maybe the error messages i got should be mentioned in the instructions. Just in case. Cuz i know it screwed me up and had me (and beezy, poor guy) running in circles for an entire day.

 

[ihop25]

great job on getting root! is it possible to pull the Contacts.apk for me? I own a mytouch3g but I'm so jealous of your contacts list and dialer.

 

[Kevin OQuinn]

it's the AOSP version. you can find the APK. don't you have the sense version on your phone? personally i like that version better, but to each his own.

 

[ihop25]

nah no sense for me.. i'm running cyanogen 6.1.
is it the AOSP version? in the screen shots it looks different. for example on the contacts tab theres the search field and 'create new contact' button as well as the column of alphabets to quickly jump to contacts.. i dont have that =( do you mind pulling it for me? i'd appreciate it so much!

edit: just in case you need it =)
adb pull /system/app/Contacts.apk c:\somewhere\Contacts.apk

 

[Kevin OQuinn]

There you go. Sorry it took so long.

 

[ihop25]

Thanks so much. You are the best!

 

[Lightos]

Has anyone rooted successfully?

 

[Kevin OQuinn]

Yes. Me. What are your questions?

 

[Lightos]

I need help. I cant get past adb shell. I get a $ not a #.please describe how you did everything from the begining. I NEED ROOT!

Follow the steps in post 1 exactly. Have patience it takes time. Did all of the programs install correctly? Next time you try copy the command permit and post it here so we can see what's going on.

[Lightos]

I posted them on page 3 but its always the same. when installing the sdk to my root hard drive you mean unzip and put it there right. i moved the rooting files provide the this post and moved them to the tools folder. when i copy and paste the words in the post it keeps saying that no directory exists. it doesnt like spaces. everything I type must be like this."d:/android/tools/adb push rageagainstthecage-arm5.bin/data/local/tmp/rageagainstthecage" in the post there is a space right afeter "...arm5.bin /..."

 

[Kevin OQuinn]

Ok sorry. When you say that you moved the files to the tools folder did you unzip them to the tools folder? You can't copy and paste them. You have to unzip them into that folder. If you don't do that you won't be able to push the files to your phone.

It looks like you can get to where you need (because after all of that stuff you are in adb shell), but something else is going on. Also when you're pushing the files you don't want to be in shell. You just want to cd d:/ where-ever-your-tools-folder-is

EDIT: so for you you'll open a command prompt and type cd D:\Users\Omoni>d:/android-sdk-windows/tools/ that should get you into adb. it does the daemon out of date restarting thing that's fine. let it finish then you can push the files.
