Ulefone S10 Pro Unbrick Ulefone S10 Pro

Hi there

I managed to brick an Ulefone S10 Pro by trying to flash a rom onto it which ended in a brief error message and then the screen went black.Since then, it wont boot up. There is just a black screen and it vibrates briefly as if it's starting up but then nothing, before repeating ad infinitum.When I connect it to a computer, the computer makes the connection sound, then a few seconds later, the disconnection sound. Nothing is shown on the phone nor the PC at this time.I have no clue what to do as it doesnt stay connected to the computer long enough to be recognised before disconnecting and nothing appears on the phone screen. Ive tried disconnecting the battery and connecting to the computer without it but the same thing happens
