Can't load android system -
This happens due to multiple reasons: user data corruption, full storage, or a temporary glitch.
If you encounter this error do these steps:
Try to force restart (into safe mode if needed), or wipe the cache. If those don't work, then factory data reset the device. This will erase all the data.
If factory reset, didn't work then a new motherboard will be required.
Note: "Wipe the cache has been removed from android 15 - 16 the only way to wipe or fix the cache is by a hard reset"
