Xiaomi Redmi Note 8T can't boot into bootloader / recovery after flashing recovery - stuck in loop

I have Xiaomi Redmi Note 8T (ginkgo). I was installing a new ROM, wiped the device, and from TWRP, flashed the recommended recovery from the CrDroid device page - SHRP (SkyHawk Recovery Project). After flashing, it said it was going to reboot to recovery, but it didn't, and it seems to be stuck in a loop. - Holding Power and Volume down - Vibrates and just flashes. - Holding Power and Volume down - Orange Fastboot logo flashes on and off. - When the buttons are released, it goes blank, i.e., the phone stays turned off. - If connected by USB to a laptop, it keeps flashing every second. - adb fastboot does not recognize the device: - using adb devices = just says: List of devices attached - adb reboot bootloader = error: no devices / emulators found - fastboot reboot = Any way out of this?
