MTKCLIENT on MT6897 (Dimensity 8300 Ultra)

[martin9753L]

Hi! I think i bricked my phone -.- i unlocked the bootloader a year back with Xiaomi Unlocker like i always do with mi xiaomi/poco phones, i never re-locked anyone so i had no experience locking it back, today i wanted to lock my phone (only because theres no way to use Uber Driver on a unlocked phone) and used the comand OEM LOCK on fastboot (yeah, i fucked it up), then the phone restarted and started showing a 'The System has been Destroyed !' after the POCO logo, and then bootloops.
I can still enter fastboot mode but cant install any rom cause its now locked (i tried with Xiaomi FlashTool), if i check the phone status now says its locked (i tried the fastboot oem unlock command, it 'work' (i dont get any error) but the phone still dead, so googling i find this tool (MTKCLIENT) but i cant make it work, so my question is, does it work with MT6897? i think not, here i post a log of what i get

Thanks!
