  3. I downgraded my LG G4 VS986 which was on the 25A build to the 13B version and it is now stuck on the Verizon Logo Screen. Any idea as to how I fix this issue?

    • Problem fixed! I did a Factory Hard Reset. Luckily I had backed up all my files and recovered everything! Thank you so much Faiq, for your informational “How-to” pages!!!

    • Hi Daniel,

      If you are running a newer version of Marshmallow (I was on 25A build), you cannot downgrade to the 11A version of the kdz file. Go to the KDZ download link above and download the 13b version. Follow the steps above and it should work. Once I downgraded to Lollipop I was able to root my phone. Good luck!

    • I had this problem with my LG4 8H11…eventhough the model is told to use the 8H1110n kdz. Not for everyone. It kept telling me the same error code rollback so what you have to do is find the CORRECT kdz file and to do so is when you look at the LGUP and the top of that interface where it says Com port then Version mine didn’t say LG4 8h1110n it said LG4 8H11v…so I found in the same folder for the 8H11 was 4 to 5 different kdz files..I saw that I already downloaded all the 8h11 files including the n but there were two v files…so it refurbished without error on the v …File…I couldn’t find anyone Helping anybody with this error and sadly the supposed techs didn’t bother to help answer this error code…I’m an IT and it didn’t take me long to figure this out…sadly these guys call themselves TECHS..lmao

      • Hi Mike H, good to hear that you figure out the issue with your G4. And yeah there are some tech guys who know nothing. They copy the methods of others and publish them and when someone needs help they don’t reply coz they don’t know anything.

  4. Will downgrading erase all data on the phone? I am planning on backing it up first but I’m wondering if it’s done successfully is the data supposed to remain on the phone?

  5. Hi, everyone, I am wondering whether I can install any firmware from any LG G4 version on my LG G4 VS986 (Verizon)!!?? Would it bring about any uncompatibility issues???

    • Don’t you ever do this to your phone. All the firmwares are intended for their specific models. You can not flash any firmware on your Verizon G4. Only flash the firmware that is compatible with your phone model or else your phone will be bricked. Refer to this guide if you want to update your verizon G4 and use this method if you want to downgrade.
