    Really appreciate your explanation of normal flash and see flash. First time I've seen anybody do it. Always wondered why app developers choose not to use straightforward names and explanations for these things; same goes for content creators; most never seem able to explain things thoroughly enough. Thanks once again

    thanks mate helped alot. My LG G4 was won from LG Insider competition and would not update via OTA. Was a PITA.
    This method worked a treat. Awesome!

    • @kona328WH
      @kona328WH 9 лет назад

      kona328WH Actually it didn't quite work. The same old ROM remained for some reason. Though the OTA update now works which is the main thing so all flippin' good!!!

    Guys if this happened to your phone, then you have to put your phone into download mode and download the LG Bridge tool (LG website). Be sure to set the LG driver properties to COM 41. After you click on the software update tab, it will automatically start downloading / flashing.
    This was the ONLY method that fixed my boot loop bricked LG G4 H-815!

      +Zainap Borzieva just connect your phone in download mode. then on your pc open device administrator and then go to COM PORT. there you will se the LG G4 connection. right click, properties. port setting, advance, and then change the port to 41. acept and OK.

    it is much preferable to use win7 instead of win8 or 8.1 there is a lot of driver problem with win8 so i tried it on another device and it worked on my other laptop using win7. please don't forget to update your c++

  • @NicholasJNadon
    @NicholasJNadon 9 лет назад +44

    If you get CONNECTION TO SERVER FAILED in the LG Flash Tool 2014, do NOT press OK. You can leave that dialog box open while the phone flashes. This will save you many headaches.

LED notification light is also jumping nonstop. & nothing is working right now. nothing! just nonstop tok-tok !

    The H811 kdz files don't show up anyone have them, its the lg g4 for T-Mobile? ok nvm I found it on the xda forum you have the link to. But now when I run everything I get the connection server failed and I also ignored it and moved it to the side and yes the bar was progressing only 3 percent thnen that window changed to "upgrade stop due to an error' then gives me steps to remove the battery inserted again and plug it back in etc. Ive tried that already multiple times but still nothing yet.. :(

    Will this work for my LG G4 which is stuck on the logo? Sometimes it bypass that and go to the optimizing applications but it crashes half way? Why is that, software problem or hardware failure? Please help I'm so desperate. :(
