Alright so I recently got the lg k7 from metro pcs and decided to root it. I rooted it using kingroot and then used supersu me so that I could install supersu instead of the one used for kingroot. It worked and then asked me to reboot my phone but when it started up again, it just stayed frozen on the metro pcs logo! I removed the battery and went into recovery mode, (by clicking the down volume+power button) but when it starts up again, it still stays stuck on the metro logo. Im assuming it is stuck on a bootloop? I also believe it is soft brick because i can still access the download mode, although it did take a while as i had to find the dang drivers b/c my computer would not recognize it.
I tried using the LG Mobile Support Tool to try to unbrick it, but it says that it already has the latest firmware installed! I cant do an update recovery either!

Sadly the 7 day exchange and return has ended and I cannot replace it, so is there any other way that anyone knows to unbrick the phone?
Thanks

The only way to fix our LG devices...including @Goongydin device
1. downloada kdz firmware file for our respective model & carrier
2. download lg flashtool & another tool on a windows PC
3. put the device in download mode
4. reflash the firmware(Stock)

check out my tutorial here if the firmware file for the LG K7 is ever released...http://forum.xda-developers.com/android/development/how-to-universally-manually-update-lg-t3280735

HOWEVER the LG K7 firmware file has NOT been released yet & LG wont release if ask...I asked once & they told me they do NOT make it & then I ask another time(different lg representative) She said that file is proprietary & so it can NOT be released to anyone outside of LG...
so I have multiple responses that conflicts with one another especially when the first conversation was with an LG developer...who ACTUALLY makes those files apparently, but inclined that he does NOT.

if you have a working one that boots, I can make firmware for it, and share to everyone that needs, I have one myself that doesn't boot

here you guys go I made stock tot.

Wow that is amazing! For the sake of educating, would you mind sharing how you made a tot file (or a link describing the process). I have been trying to make a kdz or tot for like the past week and have just been going in circles.

I have the T-Mobile variant of the K7 (LGK330BK. Is this tot carrier specific? All I need is to get back into TWRP to restore my back up or restore my system.img.

If you have already fixed your phone disregard but keep this handy. It works. On the lg ls770 which has a locked bootloader and is very finiky. I have a booting and a non booting k7 and trying to find a system.img or how to extract the system.img from the phone. All i find is how to extract img from firmware. If you could share the system.img it would be appreciated

I didn't use a DLL file, my program doesn't need it, you can try LGUP

    You may have given us a solution to unbricking the k7! but just as the rest I am having trouble without the DLL file. Can you pm the program that you used to flash your phone? Thanks.

    If someone with at working k7 could run the commands on post 19 we would know for sure.
    Intuition tells me /dev/block/mmcblk0, but I'm not sure. step 2 for boost mobile says:

    If anyone has had success with the pair of LG_Root techniques on post 25, please say so.
    Mine won't get past step one and I am considering open a new thread to address my personal circumstance.

    I was able to pull the information from my wife's k7. I was able to get to step 11 but even with knowing the dev block it still fails at that step.

    I have been going nuts trying to figure this one out. Could you please PM me with the name of the program that will flash my K7. Thank you so much.

    I am checking XDA every hour for update. That's how desperate I am right now after bricking 2 device :(
