Yes ,the reason why u should untick it is because if the build u are flashing is lower than what u have on the phone it will give u hard brick and u can't recover it without easy tag or test

@kelvinchinedu i successfully flashed v612 firmware on my ITEL P55 5G using android utility pro - xiaomi tab flasher. I ticked preloader because the build I will flash is higher than the installed current firmware.
thank you for all your help and advices.

after the phone 1st boot. on language setup, I didn't get bootloop. and then i reset factory the phone. and then i didn't get bootloop. but my battery goes 1% . still have 64% on first boot.

i will still monitor if i will get problem during usage.
