No Root Fix: How To Change IMEI On MTK Android Marshmallow Phones

So recently I discovered that an update for my Oukitel K6000 Pro had been released via Needrom but for some reason this update was not showing up yet on my device via FOTA. After some back and forth with Oukitel’s support lady, Joanna, I was made to realize that the Oukitel K6000 Pro runs on two ROMs at the moment. The first batches sold run on 32bit Android Marshmallow while recent batches run on 64bit Android Marshmallow which is better given that the device has a 64bit CPU.

So I proceeded to flash the 64bit ROM on my device and succeeded after some trial (I had to format then flash the phone with SP Flash Tool to get things working. I’ll write about the procedure soon). Unfortunately the flashing procedure erased my IMEI and fixing it wasn’t so straightforward as it has always been with previous Android versions. Most tutorials online, require root access to change the IMEI on Android Marshmallow but the method below doesn’t require root and is even a lot more simpler than the method we’ve been using to fix invalid IMEI errors on Mediatek (MTK) phones.
