Surfaceflinger backdoor doesn't work on A14

[degr15]

Surfaceflinger backdoor doesn't work on hyperos Android 14. Enabling it causes the device to always reboot.

Reproducible on Sony Xperia Stock Rom A14 with KernelSU. This is quite a fatal error. Safe mode won't solve the bootloop, even restoring the boot image won't. Are system files modified?

In logcat I saw these two lines:

02-15 23:32:16.193  5455  5455 W SurfaceComposerClient: ComposerService remote (surfaceflinger) died [0xb400006fac720b90]
02-15 23:32:16.194  5455  5455 D BootAnimation: SurfaceFlinger died, exiting...

Hope that helps.

You can remove the module on TWRP or any other custom recovery that support to access /data/adb/modules.
