    [​IMG]Hello everyone
    I need a help with my LG-Leon 4g lte

    My proximity sensor wasnt working so i decided to root the phone and turn it off. But as i was trying to root it using cmd and some files, something went wrong.After a write some commands to cmd the Phone turned off and i was unable to do the factory reset to wipe it or to revive it with any try. In the PC it shows that it is connected to the PC but its unable to install correct drivers cuz i cant choose it from my Phone.

    IS it possible that i deleted whole boot files??

    I was trying to flash it but it cant recognize it as a phone only as a weird modem.

    Pls IF you can help me.

    I ve put 50€ to this Phone and now its not working anymore.

    Can you list just what commands you used? That might reveal what happened
    But it does sound like the installed Android operating system is damaged or corrupted enough that the phone won't even boot up properly any more. That model apparently has a user-replaceable battery. Try removing the battery, leave it that way for a couple of minutes, then put it back together and try to start it up. That's not likely to work in this matter but at least worth trying.
    If you want to try flashing a stock ROM, go here and do a search for your particular model of LG Leon:
    Be sure to select a ROM that's specific to your model and country. There are instructions for the flashing process in the download page of the ROM you select.
    Follow the instructions, don't experiment.

    Well at this point don't have a lot of options. At least try flashing a stock ROM and hopefully this will get your phone working again. It it does, then try rooting it again and you'll have a working exit plan to just flash it again just in case.

    Is there a possibility to root it from SD card ? I ve made a bootable SD and put there android.
    But it seems that the android cant be loaded from SD.
    i followed this but i dont think so that its corrects one

    mikedt 你好

    FYI that's instructions for booting Android on a Raspberry Pi, or something. And those do boot from an SD. But it will NOT help you with an LG phone.

    Remove the battery, leave it out. Hold volume up while connecting the phone to the USB cable, let go only when you see download mode. Open flash tool and flash the firmware.

    If the battery icon shows it can more than likely be fixed pretty easily.

    I did leave a few steps out that follow after the above steps, if you do the steps above, i or someone on the forum will post the rest of the steps.
