Thank you for this guide. I followed the instructions to a “T”, and everything completed as expected however I am still stuck at the T-Mobile white screen. Any advice is appreciated.
Is Flashing stock ROM is completed?
I did everything as well according to your guide and I am still stuck on the LG boot screen. The phone is still stuck in a bootloop.
Do a factory reset.
I have updated a link to the Official Xda Post.There is a new Guide.You should check out that.
I am here because I want to save my data from prior to the bootloop. Things like my pictures videos documents and music that are on my hard drive. Will all of this be deleted using this process? I remember even though you factory reset on some phones, the data on your hard drive will still remain available unless you choose to do a complete wipe.
I recommend taking a backup of your data because everything will be wiped
does this really works ? pls tell me i m about to do it.
It worked when we tested.There is a link to the latest guide from Xda.You should check out that one.
How do I know which version of the H815 do I have in the “Download LG G4 Stock Firmware For all Models”?
Supported models are listed.Yeah it is for H815
my LG G4 is not entering Firmware Download mode 🙁
Please read the instruction.Read the Xda thread linked below
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
thanks for your response. But no download mode, what now?
You can find everything in the shared Xda thread, please check that out.
did you try the “Volume UP” button? Worked on mine….
Thank you for the assistance, I am really hoping it works – one question however: It appears that you recommend the 2014 LGUP, but one can use the 2016 version and you have a link to those instructions. What would be the advantage to the 2016? For what it’s worth, I obtained my G4 (VS986 – Verizon) about 6 months ago, and I really only want to unbrick in order to recover data, photos, etc. Thank you very much –
Every time i try to flash it there is an error which prevents the rest of the flashing
will this delete all data on my device?
sure will. You should probably back it up before you try it.

Good friend I have a lg g4 sprint 991 and the pc is dead only recognize it in qhsusb_bulk with these programs I can revive it your response
Did the trick few months ago, downgraded even disabled 2 big cores and worked great till now. Now started boot looping again, but this time can`t get even to download mode, it shows is loading download mode but restarts on and on, or when factory reset restarts when upgrading apps..any ideea?
i have LG G4 and its not getting switched on .. only LG logo is coming up ? should i install LG Flash tool to fix it ?
You do know that this is a hardware issue. Flashing firmware won’t fix it on most. LG repaired these under warranty but now there is a huge lawsuit over these.
doesn’t work for me.. seems like a hardware issue… i tried everything.
