Do not Flash this ROM via TWRP, use fastboot instead
To get started, make a back-up of all your device data since everything will be wiped
Now follow the Instructions Carefully:
- Download the Evolution X ROM from here
- Extract the zip file and copy the contents in the platform-tools folder on your PC
- Open Powershell/CMD in platform-tools by clicking Shift+Right Click, connect your device and type adb devices to make sure your device is identified
- Now type : adb reboot-fastboot or fastboot reboot fasboot

- Now type : fastboot devices to check if your device is connected
- Now type : fastboot -w (This will wipe all the data on phone and it is mandatory or you’ll end up in a bootloop)
- Now enter the following commands one by one:
- fastboot flash boot boot.img
- fastboot flash dtbo dtbo.img
- fastboot flash system system.img
- fastboot flash product product.img
- fastboot flash vendor vendor.img
- fastboot flash vbmeta vbmeta.img
If you get some error while performing the flash, try uninstalling the platform tools and reinstalling them from here or contacting help from here
After the flashing is complete, type: fastboot reboot
You’re all done, enjoy Evolution X OS
