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.
