I have tried this on both Ubuntu with the linux option and tried on Windows, neither works. I have followed the instructions all the way and it keeps saying permissions denied. Is there another way to do this?

same here, though i suspect my issue is related to the fact that i have a lg-e400r with the V11e software. or maybe my carrier (Rogers) has made the file-system read-only.

this is what happens when i run the script in linux and windows:

Code:

hi, just one question:

in case the rooting goes wrong, have you any way of returning back the phone to its original state? (for example, do you have the original firmware from rogers/fido?)

Download the Original Firmware in here : http://lg-phone-firmware.com/index.php?id_mod=11

Hello,

I tried reinstalling the driver. Still getting the same "link failed Permission denied" error. Hopefully a solution is found for the E400R.

Thanks for your help!!
