    Its repeatedly getting stuck at 90% and i am doing as mentioned by you(i.e. restarting while its connected) and I am getting the done, but the root checker is saying it’s not rooted and Super SU wasn’t installed

    Not working for me either…. At&t LG G2 5.0.2 lollipop stuck at 90% on computer and 0% on phone firmware update…. have tried a number of times on resetting it downloading a different one click root and still the same…

    • Mayur says:

      Check the note above. Reboot the device manually while it’s connected and it’ll show 100%. If it doesn’t shows SuperSU installed after reboot then repeat the procedure again.

    ATT LG G2 D800 Lollipop 5.0.2

    It worked! First two times failed… third times the charm. I wonder what caused it to fail the first two times?

    Thanks for the article! Very easy to do, took less than 10 minutes.

    If you are stuck at 90%, you can try the script method and make sure run cmd in Administrator, and cd to your folder. That work for me.

    If the phone not recognize, try to switch between MTP and PTP options.
    MTP not worked for me. i selected PTP option.
    If Serial port not found! insert the phone manually into Download mode.
    Disconnect the USB cable and turn off the phone.
    Then press and hold the Volume Up button, and while you\’re doing that connect the USB cable again.
    mine completed at 100%.

      Tried your move; got an error prompt on my laptop at 90% saying The program can\’t start because MSVCR100.dll is missing from your computer. Try reinstalling the program to fix this problem; then finishes at 100% done but my phone got stuck at download mode; any ideas?

  15. Mike says:

    If the Root works properly, Is it supposed to wipe everything and have a fresh install?
    I keep re-rooting and nothing seems to work.

    can someone help doesn\’t move pass 75

    • Brian says:

      Mine is also stuck at 75%.
      Checked devices and there is a exclamation point next to the MTP USB Device. (also yellow exclamation points next to CDC serial & LGE Android phone).

      I think that is the issue. I have tried updating the drivers and it hasn\’t fixed anything.

  22. stone821 says:

    Thanks so much, you save me

  23. browarsk says:

    tried 10 times, everything goes great, didn\’t even stopped o 90% once, but it doesn\’t shows SuperSU installed and Root Checker says that root is not properly installed

  24. Banan says:

    Hi, i had problem with getting stuck on 90 % many times too. I uninstall my old driver and install driver ver. 3.14.1 (from this site) and than it works at the first time (with long pressing power key for reboot). However i can´t know, if driver is the reason ;).

  25. aphx says:

    No error
    No Stuck
    But No root on my LG G2 mini

  26. jason says:

    stuck at 75% on computer and 0% on phone, it says it cant find the serial port and says to manually enter download mode, so i did that but the app never reactivates to start the process again, just stuck on the firmware update screen.

  27. is there any technique to root without pc.

  28. Steven says:

    Worked after a couple tries, thanks a bunch!!! For folks with issues, try one of the following:

    1) when the process seems to be waiting on device connectivity alternate the connection type (switch between MTP and PTP)
    2) if option one fails try starting with PTP as the connection type and then alternate the connection

  29. Another Steven says:

    Worked first try (G2 d801 T-Mobile). Just waited while it did it\’s thing (seemed to take longer than i thought it would, just be patient). Thanks Mayur.

  30. Mike says:

    This worked perfectly, thank you!

    Many thanks. Worked the first time I tried.
    Lg G2 D800 (AT&T) Lollipop 5.0.2

  36. Joel says:

    Mine\’s LG has been stuck on that firmware screen for a while. I\’ve tried holding down the re-start button, but have had no joy. I\’ve noticed some commenters above mentioning their phones being plugged into a computer. How/hwy would a phone be plugged into a computer? Is this something which I need to do to get rid of this firmware glitch?

  37. vin says:

    Lg G2 D800 (AT&T) Lollipop 5.0.2

  39. Alius says:

    I went through with the whole process flawlessly. It even reached 100% and rebooted for both the computer and phone. That\’s great. But now the phone will not boot. it is stuck at the LG logo and the notification lights keeps blinking green.

    Please help me!!! Is it too early to start panicking??

  40. Onie says:

    Hi,

    Does it need your computer or phone connected to the internet while performing the rooting?
    or you just need internet when downloading the files?

    thanks if someone can confirm

  41. alpin says:

    i tired.
    every time stuck at 90%
    damn!

  42. Gene. P. says:

    Thanks for your tip. Mine kept getting stuck at 90% and then after I followed your advice which was holding down the power button while still connected to the computer the phone restarted and process was complete same as your screenshot.

  43. Alex says:

    Hi everyone, I have done the process, supersu and rootchecker shows ok, but when setting a recovery rom by an applications (rom manager or autorec), they are security locked and doesn\’t work. As the recovery doesn\’t boot its impossible to force another rom…
    Any idea to resolve this problem ?

  44. Frosti says:

    Works for me every time, but after last reboot SuperSu doesn\’t appear on my phone.

  45. arturo says:

    genial funciono en un lg g2 vs980 en el quinto intento!!!

  46. JohnG says:

    I got it to work, basically the first time failed, the I hit Cancel and reboot by G2 then the second time it works. Thanks.

  47. David S says:

    My phone battery would not wall charge normally after any rooting. I first rooted my LG G2 D800 with KitKat, then I recently restored and upgraded to Lollipop then rooted. The charge would get stuck at 65% or 73% so I replaced my two year old battery, no change. I kept on having to unplug my cable then plug it back in and it charged very slow. It would also connect and disconnect the charging repeatedly. It drove me crazy! After some research I realized that not all wall chargers are the same. My LG came with a 1.9A charger. Most cheapo chargers are 1.0A. I purchased a 2.1A charger (higher charge rate used for iPads/iPods) As soon as I started using that 2.1 Amp USB wall charger my charging was back to normal. I hope this information helps those who have the same problem.

  48. David S says:

    On my LG G2 D800 my install got stuck at the 90%. Rebooting and repeating did not work for me. Through trial and error I found two ways to get the install to 100%. The first time I got it to root successfully I simply pushed my Volume Up button and it went to 100% install immediately. The second time I rooted the Volume Up (repeat) or Volume Down (repeat) buttons did not work so I just pushed my Power button, did not hold it in, and after several times (repeat) it finally went to 100% install. Each time I was patient and waited a few minutes at 90% before doing what I did to get the install to work 100%.

  49. k54 says:

    it doesn\’t work with samsung cable, when I though that I must use ORIGINAL LG cable at first time all gone ok !

  50. Aleks says:

    Who have this problem with 90%, the fix is really simple, put the phone on charge mode, start one click root when it cannot detect the phone, change it to PTP mode, when restarts, PTP mode again, had this issue 5 hours busting my head, i resolve it that way

  51. Mr Majestyk says:

    Hi guys, I have solved the problem for those stuck at 90%. I think it has to do with the USB you\’re plugged into. I was using a USB3 port and it would never get past 90%. As soon as I switched to USB 2 port, it worked immediately. It took me about an hour to realise this. Phone is rooted!!

  52. nbi says:

    This does *NOT* work for a T-Mobile LG G2 D801 running Lollipop. \”Looking for LG serial port\” times out with a registry error. This happens under both Windows 7 and Windows 10.

  62. A third Steve says:

    It did not reboot into Download mode. It rebooted into \”normal\” mode and I\’m stuck at 45%, \”Waiting for device\”. I tried a couple of different methods. shutting down and restarting, holding down the up key and power key or just the power key. It will then go to 75% and stay there \”Waiting for Device\”.

  63. Adam says:

    I\’m stuck at 90%, 0% on the phone. Long press power button does not work at all, nothing happens. Phone does not reboot. When I try to press \”cancel\” in the program, also no response. What now??:(
