      Latest version is H870I20a_00_TIM_BR_OP_1122.kdz

  • 12/09/2019 20:23:20 henriqueoafonso says :

    My LG G6 H870I is bricked. Always gets an error message on LGUP. I'm trying to install the H870I20b_00_OPEN_SCA_OP_0115.kdz, but it gets an error message every time. I even tried to manually change the folders on the LGUP folder, I've extracted the dll with the firmware extractor, I've changed the dll on the LGUP\model\common folder, but in 99% it gets an error message again.

    The download of the firmware here takes like 4 hours to download, and I have a 100mb connection. It's getting to my nerves. I'm very afraid of losing my phone. Please, somebody, help me!

    • 12/09/2019 20:26:34 henriqueoafonso says :

      I reinstalled the LGUP and I get a message saying LGUP can1t load the model[C:Program Files (x86)\LG Electronics\LGUP\model\common

      • 12/09/2019 20:31:30 admin says :

        Try use UPPER CUT.

    • 12/09/2019 20:26:44 admin says :

      Which firmware version you use before?
      Speed for different country is different and you must can't forget. We free fan club and you download free.

      • 12/09/2019 21:40:58 henriqueoafonso says :

        I think it was the H870I20a_00_TIM_BR_OP_1122.kdz. I believe so.
        By using uppercut you mean to use with the all original LGUP 16? Or with the configuration that I told about?

        • 12/09/2019 21:43:26 admin says :

          For H870 you need use LG UP 1.14 + UPPER CUT. Like in our video.

          • 12/09/2019 22:21:50 henriqueoafonso says :

            but it is the H870I, not the H870. I used the uppercut now and a error message appeared again. I'm trying another firmware. Now I'll try the H870I10c_00_OPEN_SCA_OP_1114.kdz.

            • 12/09/2019 22:24:27 henriqueoafonso says :

              the error message appeared at 70's percentage, not at the beginning. The uppercut was able to recognize my phone, but in the middle of the process I receive an error message. The most part is 0x2bc error.

              • 12/09/2019 22:41:05 admin says :

                You can't flash 20b, 10c. You downgrade and this brick your phone.

                            UPPERCUT doesn't work anymore in my computer. It says that UPPERCUT.exe is missing. I tried to extract the LGUPc.dll and to put it on the common folder, renaming it to LGUP_Common.dll, the LGUP recognised it, but I always get an error message. My phone goes from 12% on the percentage bar to 0% again in the middle of the process, and I get an error message.

                            • 12/10/2019 19:41:32 admin says :

                              If UPPERCUT doest't work on your PC you need try use another PC.

    Dear webmasters,
    First of all I'd like to thank you for making the files available so we can upgrade our devices.
    I would like to inform you that the firmware named "H870I20a_00_OPEN_SCA_OP_0712.kdz" when installed appears as v20j. Is this a flaw or is it correct?
    Another point is the file "H870I20a_00_CLR_BR_OP_0703.kdz". I tried twice but it seems that there is some problem with this file because in two attempts the device does not leave the screen "LG G6 Thinq".
    I would suggest that the files have been fixed.
    My location is Brazil.


    • 08/20/2018 21:27:02 admin says :

      LG made error in H870I20a_00_OPEN_SCA_OP_0712.kdz file name and inside is 20j.
      When you flash H870I20a_00_CLR_BR_OP_0703.kdz you downgrade from 20j to 20a. Try make hard reset.
