    Default Help anything to get my lg optimus l9 p769 working

    My phone is an Lg p769 T-mobile(Bricked)V20H
    All i did with this phone is rooted it, to get root access to moving files.
    I have a Locked Boot loader.
    I Accidentally installed chain fire 3d without knowing its not compatible with JellyBean.

    So my problem is I'm stuck in boot loop.
    when i turn it on its stuck on Lg logo. (No Security Error)
    I am able to get into S/w upgrade mode but not Recovery mode.
    My PC (Windows 7 Professional) won't detect my phone when in its in S/w upgrade mode. But it shows as LG modem
    Device driver software shows my phone when connected as s/w upgrade mode as Unidentified Device - Unplugged
    I installed the my phone driver from the Lg websites even the latest drivers 3.8
    But still its not connected
    I tried following guides to offline Flashing with lg mobile support tool to flash stock rom to my phone. but still my phone won't get detected
    getting stuck on 15% when upgrading.
    Adb also dosent detect my phone

    all i need is to get anything to get my phone working even if i have to wipe everything.
    i provided images to see what I'm getting when my phone is in s/w upgrade mode and connected to my pc
    Sorry I'm for my bad english

    Have you tried the following from powered down (phone off)?

    Hold Volume Down + Home + Power buttons for 8 seconds until the phone wakes up. That should do a factory reset and allow the phone to boot. You would loose all your data...

    Also there is an LG Mobile Support Tool that may help:
    LG Optimus L9 P760 hard reset
    LG Electronics: T-Mobile Device Update Instructions | LG USA
    Nokia Lumia 1520.3 (Factory Unlocked): Windows Phone 8.1 w/ Lumia Cyan
    Dell Venue 8 Pro (32GB): Windows 8.1 Desktop OS w/ Office 2013 H&S

    if the user that created this post is still wondering you will need software upgrade mode but you will also need the modified version of LG's utility i made a mistake once modifying a file in my rooted phone so it would show the LG logo then go to a black screen i put it into S/W upgrade mode by removing the battery and when the program prompted put the battery back in after that my L9 was back to a unmodified v20h (no root or file tampering)
