WARNING: Your data will be erased...
Use these two links:
1. Download the service firmware from the links above for your respective model and extract the "dload" folder from it. It will contain a file called update_sd.zip and two folders - CLT-L09_hw_eu and CLT-L29_hw_eu, each with a respective secondary update package, leave these in the folders and delete whichever folder isn't relevant to your device e.g keep the L09 folder if you have the L09 folder and vice versa.
2. Drag the dload folder to an exFat formatted USB drive and have an OTG cable handy as this phone hasn't got MicroSD support.
3. Plug the OTG cable with the drive in the phone and now go to the phone dialer and dial *#*#2846579#*#* and go to Software Update and then select SD upgrade.
4. EMUI 9 will start installing and your data will be erased after. Note: OEM unlock will be blocked, this is a known bug in EMUI 9 for now and should be fixed in a later update.
5. Enjoy EMUI 9!!!!!!!!!!
Looks great but is there a file for the non pro non lite version
