Bootloop Protector
- This module try to protect your device from bootloops and system ui failures caused by Magisk/KernelSU/APatch Modules.
- Generally , This Module can fix these type of bootloops if their cause is Magisk Modules.
- The device repeatedly restarts but may show the boot animation before crashing and restarting again.
- The device gets stuck at the boot animation and never progresses to the lock screen.
- device boots successfully, but SystemUI fails to start, causing a black or unresponsive screen."
Installation
- Flash it in Magisk,KSUorApatch
- if you flash it in custom recovery, it will disable all the magisk/KSU/APatch modules for no reason. Flash it inTWRPonly when necessary.
Bootloop
- If a bootloop is detected, , it will automatically disable every Magisk/KSU/APatch module and set the permissions of all general scripts (scripts placed in - /data/adb/service.d,- /data/adb/post-fs-data.d- /data/adb/post-mount.dand- /data/adb/boot-completed.d) to 644
- You can manually enable each module, or you can use the action button. Using the action button will also set executable permissions - chmod +xfor all general scripts
Recovery
- Flashing this module in - TWRPor- custom recoverieswill automatically disable all Magisk/KSU/APatch modules and general scripts. Your data partition should be accessible otherwise, it won’t work.
- It may not work with all recoveries. 
How does it work?
• Each time the device fails to complete the boot, the module creates a “marker”
- No marker files: it creates the first marker (marker1). 
- One marker file: it creates a second marker (marker2). 
- Two marker files: it creates a third marker (marker3). 
- When three markers are present, the module considers the device to be in a boot loop , and it disables all Magisk modules by creating a disable file in each module’s folder. This action prevents those modules from loading during the next boot, which may help the device boot correctly. 
- The module waits for the boot to complete, checking every 5 seconds. If the boot does not complete within a set timeout period (2 minutes by default), the module assumes there is a boot problem, disables all Magisk modules and general scrips, and reboots the device. 
- The module also monitors the state of - zygoteduring booting and disables all modules if unusual behavior is detected.- whitelist
- you can add module-id to - /data/adb/YABP/allowed-modules.txt,and script names to allowed-scripts.txt, those scripts/modules wont be disabled even if a bootloop is detected
SystemUI Monitor (optional)
- some modules, especially - customization modules, may sometimes cause SystemUI to crash. Enabling this could help in tracking and resolving such issues.
- You will be prompted to disable or enable system ui monitor while installing the module. 
- if enabled , then The Module checks the status of the SystemUI process every 5 seconds. 
- If SystemUI is not running, the module starts tracking it and if SystemUI remains inactive for more than 25 seconds , or if it crashes too often the module assumes a failure of the device and it - disablesall the magisk modules and general scripts and triggers a- reboot
- To - disablethe systemUi Monitor , you can create a file named- systemui.monitor.disablein- /data/adbor you can just run
to enable the systemui monitor , you can just remove that file, or you can run , (changes will take place after the next boot)
- Logs of this module will be found at /data/local/tmp/service.log
- you can run rm -f /data/local/tmp/service.logto clear the logs.
Limitations
- If the cause of the bootloop is not related to Magisk/KSU/APatch modules, this module won’t help.
- If any modules directly modify system files, this module won’t help.
- In cases where a module uses an incompatible system.propor causes a bootloop during the early boot stages (post-fs-data), this module may not be able to disable it in time.
In these cases , you can always flash it in TWRP to disable Modules
