[Question] Help me Plus P20 PLUS

[Djzebulon]

Good morning to all of you, 
I'm new to the forum and I admit I'm a little lost
I bought an unbranded Chinese Plus P20 PLUS phone with mtk6572 processor, unfortunately that contained a virus. the backup went wrong and since the flashing it just loops by making music to start without turning on the screen!! (black) I managed to debricker it with SP_Flash_Tool_v5.1924_Win, but it no longer appears under mtk droids tools . If by chance someone knows the model Build number :
PLUS HS_GT033_PLUS_M512_D2_5.72_V0.5_20191202
Build date UTC : 20191202-130322
Android v : 4.4.2
Kernel v : 3.4.67 (lhf@lhf-LastTry) (gcc version 4.7 (GCC) ) #4 SMP Mon Dec 2 23:33:48 CST 2019
It would do me a great service!!
