Hi, I'm having a problem with my phone (C21Y RMX-3263) being stuck in bootlop after accidentally updating magisk via direct install option (has been rooted once already with patched boot img and spd tools). I figured I should just flash the old firmware but neither SPD research and upgrade tools work properly, for about 10-30 seconds all is going well, but then it just gets stuck on downloading, on different parts like super, or boot randomly alternating between attempts. I've left it on for about 4 hours and tried multiple times with no progress at all. There is nothing visible on the screen but holding the vol down button and plugging the cable in seems to initiate fastboot. I've tried using different versions of the tools and different firmwares for my model but nothing seems to work. The bootloop itself is very weird - the phone buzzes and the splash logo appears, afterwards starting to glitch out extremely eerily, the colors start to become weird, white lines dance on the display and after that it turns blank and flashes gray for a few seconds before turning off, looping and doing it all again. Pretty sure this isn't a hardware issue as the phone was working fine before. Assistance would be much appreciated
