VTR L09 hard bricked

[chinole]

Hello
While trying to update to Oreo my phone has given an error in the update. I tried unbricked through DC_Phoenix v51flashing factory firmware but it has also given error in the update and it has turned off and no longer turns on the screen, nor does the LED, does not respond to the buttons, does not turn on load LED. Nothing at all. My phone has died. I connect it to my pc and it has not been detected in device manager. Please I need help. I have read that with method 3 something could be done but I do not understand the steps to follow.
I`ve purchased 3 day license and again can not see View Testpoint Image!
Please help Valdemaras

Hello, you need to select factory firmware/board software that has "testpoint" in it's name on DC-phoenix for testpoint image button to appear.

Make sure you have hisuite installed on pc before doing repair. Otherwise you won't have necessary drivers for when phone enters/tries to enter fastboot mode to complete flashing.

Drivers installed correctly but not enter fastboot mode. Led off, not charging. Pc only recognizes device when doing test point HUAWEI USB COM 1.0
PLEASE HELP

If not possible to flash with board software then only way to repair it is by replacing main board of the phone.
