Flashing Steps Evolution X 11.5 kernel 4.19
Jiro* If anyone is still on AOSP k4.9, please return to MIUI
*Make sure to back up all important data before flashing. Because kernel 4.19 is not compatible with kernel 4.9, a clean flash is mandatory
*Clean flash involves formatting data which means you will be loosing data stored in the internal storage of your device, data in SD Card should not be affected. I will not be responsible for any loss of data.
