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:

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!!

hi! just want to ask, after I root my e400, will restoring to factory settings through the Settings Menu lead to bootloop? or should i do the restoration (in case i need it) through button combinations (HOME+VOL DOWN + POWER)? thanks in advance!

I flashed today with KDZ latest N firmware. Now I can't root the device.
Should I downgrade? This is what the root tool prompts at the end.

Code:

Solved Run Superoneclick V1.7 rageagainstthecage and in 5 min your LG E400 is rooted.

    Stealing...

    In case anyone is still reading this, I just wanted to mention that I don't appreciate having my work stolen. "Zeref_Dragneel" took my LG Spectrum exploit (http://vulnfactory.org/blog/2012/02/19/rooting-the-lg-spectrum/), replaced a few words in the instructions, ripped my name out, and put his on it. This is plagiarism, plain and simple.

    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?)
    Click to expand...
    Click to collapse

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

    Flash it in KDZ ;)

    Or you can use Gingerbreak app for Unroot it :D

    This tool is for E400 not E400R. You can try Gingerbreak or Superoneclick :D
