Hi My G2 was bricked that fastmode started and every time a enter a command it would hang and not process for example fastboot erase recovery then it would have a recovery...... and nothing.
Hey still looking to fix? Look for lgg2 stock firmware and use LG flash tools to put 4.4.2 back on and it will be all original. If it's the d800 Google Supersport and big fau and you should be able to find it. It's a 1.9gb installer with complete step by step instructions on the xda page. If I fine it later I'll edit this
first install lg usb drivers and then pda Net drivers then go to fastboot mode

I have messed up my lg volt it was on the stock rom zv5 and was running fine with root. I decided to flashify a deodexed version of my rom onto my phone, this of course went wrong as all my phone displays is the Lg boot animation with Fastboot in the top right corner i cant enter recovery mode as I have a bad recovery. I can open up the adb sideloader within Android System Recovery but have no idea how to get it to work as my command prompt does not recognize the command. I have tried a factory reset and rebooting. Help please I am getting desperate. FYI I am 14 and my knowledge on flashing is minimal.

Hello, and welcome to XDA! You could try to adb sideload a rom and flash it. Or fastboot flash a working recovery onto your device, and then sideload a rom and flash it. Or you may have to reflash stock firmware onto your device to get it to work. Here is a guide as to how to flash roms: http://forum.xda-developers.com/wiki/index.php?title=Flashing_Guide_-_Android. To sideload, the command is simply "adb sideload name of file" without the quotation marks. For further help regarding your problem, you can register and post your questions in the XDA help forum: http://forum.xda-developers.com/general/help.
Good luck!
Hi!
I have same problem as here:
http://forum.xda-developers.com/g-flex2/help/h950-5-1-1-v11z-bricked-bootloop-lg-t3223221
But i dont delete rootedsystem.img
I tried this guide:
http://forum.xda-developers.com/g-flex2/development/lg-g-flex-2-ls996-zv6-sprint-5-1-1-t3169212
But first time dont work, then i copy bad copy command and i run "dump" command, what does it mean?Its all deleted?I think it shoud be for backup no?And when im now trying to do flash cmd, the hashtag dont dissappered.
Any idead?I have last V15C rom, so i dont can use LGFlashtool, because downgrade doesnt work?
Yes you can use LG Flash Tool to restore your phone to stock and unbrick your device. Download V15c stock kdz file and flash it with lg flash tool from download mode (turn of the phone, hold volume up and connect your phone to pc). Run lg flash tool, browse for v15c kdz, select csm flash to format all data, and pres start, wait for 5-10 minutes and watch progres bar on the phone. If lg flash tool crash after phone reboots, never mind it is ok.
So you do not need to downgrade because there is a v15c kdz, I use this method to unroot and revert everything as new.

Yeah, i done it yesterday before your post.Luckily i have found all Flex 2 firmwares, so i flash correct one.But thanks for your answer.
Hi
This is short guide on how to install latest available Firmwares on a rooted lg stylo 2 plus ms550 [Note: this will remove root and twrp from your device and you will need to re apply the steps in my twrp thread to flash twrp and get the root back]
Steps:
1- download the latest kdz from here
https://lg-firmwares.com/lg-ms550-firmwares/
2- download lg up 1.14 from here
http://downloads.codefi.re/autoprime/LG/Flash_Tools/LGUP/LGUP_Store_Frame_Ver_1_14_3.msi
3- install lg up, open it and choose the upgrade option
4- choose the downloaded kdz and press start
5- wait for the phone till it reboot to the download mode, install the new firmware and after the flash is done your device will automatically reboot back to the system.
enjoy
Awesome appreciate your work!!!

I want to first thank Messie2050 for all his work on this. I know I'm making a mistake when I'm attempting to root this phone but I don't know what exactly I'm doing. I follow each step to a T. When I get to opening the command prompt and type in fastboot etc, windows says it doesn't recognize the command "fastboot" and to make sure I typed in correctly. I also tried on my netbook which is running Linux. It's slightly easier however it just waits on the device. I don't know how to extract the twrp file on a Linux machine. Can anyone help? I've tried everything to root this phone!
I am getting a msg that says invalid kdz....
Yeah, still not sure whether to use MTK or MTP.
My LG UP said LGUP can't load the model (C:/Program Files (*86)/LG Electronics/LGUP/model/com
On stock 5.0.2 I have tried everything i can think of: tried rooting using a oneclickroot made for the model,kingroot wont install,cant boot to download or fastboot but recovery is working, tried booting to download and fastboot using adb phone just restarts to system also tried installing apks using adb, tried using linux as root(virtual machine) and adb to flash laf.img just get errors and no permission. I likely missed something with linux? opened the phone up shorted to qhs usb dloader 9008 mode to try and use boarddiag(I did this a few years ago to fix my LS980 and boarddiag worked the first time no problem) but the D415 i just get the 2 common errors everyone gets something like no response from phone, and not found in the flash mode selecting correct com port etc. The only thing i can think of is to buy a board. If only i could just manage to flash the download mode (laf.img)
As above stated I've bricked my LG V20. Completely black screen, no download mode, no anything.
I've taken a few steps towards unbricking it and none of them were successful:
Uppercut and LGUP (device not found)
QFIL (Sahara errors and connection errors)
Either I screwed up something in the "revival" process, there is another method I don't know about or the only thing left for me is buying a new board.
I would greatly appreciate help.

Once you flash h918 firmware on a non h918 you're done, there's no recovering it.

EDIT: forum made me remove all links to post, but then let me edit and added some back.
I have just a little experience with rooting, just enough knowledge to be dangerous, but I'll try to help anyway.
I thought I had bricked my phone this weekend, but managed to get it going again.
Wrote this up from memory, but pretty sure its right.
I needed to do this because download didn't work, ie Volume up + plug usb to PC = download mode and if you start the patched lgup and it doesn't find your v20.
At this point, I thought the phone was bricked, so had nothing to lose.
Install fastboot and adb: link
Download H915 v10e KDZ . H91510e_00_VTR_CA_OP_1205.kdz.
Download latest LT Extractor SW . https://forum.xda-developers.com/showthread.php?t=2600575
Run the extractor sw, select the kdz file downloaded above and extract DZ file from it
Select DZ file, and extract lafxxx.bin
REMOVE ANY NUMBER FROM THE NAME OF FILES and change ext to .img ( SUPPOSE YOU GET laf21345.bin THEN RENAME TO laf.img)
Note that laf is "LG Advanced Flash".* It loads download mode and lets you write a new kdz.
Copy laf.img to folder with fastboot installed in step 1
Download and install lg v20 usb driver, under "LG Universal Mobile Drivers Download" at this link:
https://www.lg.com/us/support/help-library/lg-mobile-drivers-and-software-CT10000027-20150179827560
Hold Volume down then plug usb to PC to put phone into fastboot mode.
Go to windows Device Manager, and should be a row for android.* Click and make sure its working properly.
Run Command.com, go to folder with fastboot,then run
fastboot devices
fastboot responds with device info.* If not, figure out why before proceeding.
fastboot erase recovery
fastboot erase laf
fastboot*flash*laf laf.img
fastboot reboot
exit
You should be able to connect in download mode now.
