My phone was bootlooped so i hard reset it but when i reboot the phone it ddn't boot and also recovery mode seem not working. Then, i have decided to flash a stock ROM(updated one) using SP Flash tool. I checked all except preloader and successfully downloaded it. Still my phone no sign of booting up when i power it on and it doesn't show battery percentage when charge it.

I tried format the whole flash and reinstall the stock rom with preloader and firmware download was successful but still it is not booting up.
I've read a lot that it was HARD BRICKED.
I tried to consult in a mobile repair shop but their pc cant detect it. I DONT KNOW WHY cause my pc can detect it so it still have a chance to repair, maybe. I can't find any solution so im in here thanks to sir @enigmaSmile

I already unbricked 2 mtk devices. Im not a professional so i cant find where i've been wrong.

I ran memory test in SP Flash Tool, dont know if it can help:

It seems the firmware you've flashed aren't for your variant.
What caused the bootloop in the first place? Was it something you did or it began suddenly
Also, was flashing of the other roms also successful?

I dont know the cause of bootloop it's just suddenly happened after I finished charging it up, that's when i decided to factory reset it via recovery mode and after reset it was bricked so i ended up flashing the Stock Rom, i tried every version of rom for my phone model and it was all successfully flashed. But still not working.

seems like the roms are not for your build / variant
how many roms in total have you tried?
and did you perform a factory reset after flashing the roms?

Seems you'll need to search for more firmware for your model....unless this is a hardware issue

Unfortunately that's all the rom available in surface web for my phone model... Sad
I still cant decide that this is hardware failure because it's still able for flashing and my pc still can read the phone.
