rare cases ang bootloop pagdating sa rooting
kung compatible yung makuha mo na custom recovery (TWRP) pwede mo naman itemporary boot via adb at wag mong iflash para mapunta sa recovery mode at saka mo gamitin iflash ang supersu.zip(old school of rooting) file or magisk.zip (new way of rooting-systemless) file para maroot.
eto lang key
-download and extract adb portable zip sa desktop
-download twrp.img para sa phone mo at save mo sa loob ng adb folder
-punta ka sa adb folder hold shift+right click para open command window then boot mo twrp temporary
-supersu or magisk zip file pili kanalang kung alin dyan tas save mo sa sdcard
-flash mo yang zip gamit twrp, reboot and you're done
troubleshoot:
-bootloader unlock mo if ayaw maflash yung mga zip file kung install aborted lalabas
