Good, you have to look at software updates, box or dongles that we have, open the z3x shell and go to software, lg and you will see that there is an update of lg tool 2.64, when you have installed lg tool 2.62, these small errors they make procedures wrong or kill the phones, you have to be aware, it is a tip, if it fails in the flash, it is octupus lg, umt has lg module too or test point, loader, and convert firmware of that lg model to xml.

Yeas I made a mistake, I used the Z3X to make it easier. Should use LGup and Uppercut. Thanx for the lesson. If you have a way to convert a kdz firmware to an xml please share.

Good again, it is a tip, I am not the one to give lessons, if the phone detects it in the device manager with the driver qualcomm 9008 then if you must convert the firmware kdz to xml, if you have umt, in the module lg what you can do it, if you have hydra tool module qualcomm you can also do it and if you have ufi box or dongle you can also do it.
Now if you can enter lg download mode, with lgup you can do it through kdz.

Regards.

Hi again. As I told in my origuinal post the phone it's in download mode but the PC don't detect it. Very strange. Only in fastboot mode and this set does not allow bootloader unlock so no flashing in fastboot mode either. I have umt and several other tools but for flashing in qualcomm mode I'll need to open up the device and make testpoint. That I'll do as last option. Thanx for your help anyway.

That looks like you have a cable problem. I flash 100's of these with no problem. Why it disconnect at 50%?

Good and good contribution sir, if you have read it, the latest update of the lg module of z3x works fabulously even better than octopus, the drivers also influences.

Regards.

Hi, I solve the problem OK. IT was NOT a cable problem. Medusa Pro did the job just great flashing the .kdz in qualcomm mode. Thanx to a clangsm member who pointed at me.
UMT pro could not flash it, even with the software converted to html.

Just to let you know how to solve this:
First. Problem was the set H873 suffered a flashing error on Z3x trying to flash 9.0 Pie.
- After reboot set got into download mode by itself but PC did not recognize it.
Solution:
Enter EDL mode via testpoint and flash this firmware H87315d_00_OPEN_CA_OP_1226.kdz via usb. After the set will get into download mode again but this time PC will recognize it.
- Flash latest kdz with LGUP via uppercut (what I should do in the first place)
Problem solve.
Thanx for your concern and help.
