device auto reboot when pingpone exploit . fail root, the log as follows:

Device detected: SM-G9200 (LRX22G.G9200ZCU1AOD9)

Try to find address in memory...
Attempt msm_cameraconfig exploit...

You need to manage to get remap_pfn_range address.

Try copying kernel memory... It will take a long time.
Attempt pingpong exploit...

then it's reboot. failed root
