Dooge X5 Max Pro Bricked[Urgent]

[Ap0sGR]

Ok, i have a doogee x5 max pro phone and i tried to root it by flashing twrp recovery using sp flash tools. While flashing i got the error "PMT Changed for the rom it must be download". So i did a small research on internet and i found out that i needed to format everything except bootloader. This succeded. So after that i tried to install the firmware with this succeding to. Unfortunately the time i tried to turn phone on it was dead. SP Flash Tools wont detect it anymore. Please help me cause the phone is not mine and its brand new! I can rate my self as moderate android user. I am starting to lose my mind,i have 5 more days to fix it and i tried everything my little brain could think of. Any advice will be awesome. Thank you!

Leave the phone plugged in. Hold the power button for a few seconds until it vibrates or the screen shows something.
Check if flash tool detects it now. Load the scatter file and try to flash it again.

UPDATE: I almost fixed it! I had flashed wrong preloader so phone wasn't recognized by SP Flash Tool. I fixed preloaded with a little trick from here: link. After that i flashed stock rom downloaded from doogee.cc but phone will not boot resulting in a total black screen. When i hot Power + Vol Up it takes me to another screen:

Select Boot Mode:

Recovery
Bootloader
Normal

Doesn't matter which boot mode i choose i just get a total black screen which means i get nothing. Idk what is happening! Any further help would be appreciated! I constantly try to bring it back working with little success and small improvements.
