Same here, with a brand new BV5500 Plus.
The problem came, like on many other MTK phones, after reformatting completely the phone.
On some other phones from other manufacturers, a special file (attestation key) must be flashed with the SN Write Tool.
Example for the Cubot X19: [Cubot X19][Fix]Red Google Key watermark whi… | Android Development and Hacking (xda-developers.com)
How is the procedure with the BV5500+ ?

Hi
When you completely reformat and flash a MTK device, you probably will get two problems at the same time.
First problem is the Not Verify mark, this is only a cosmetic problem which will be hopefully be solved soon here.
Second problem are missing or wrong IMEIs.
Why?
When I began to be active in smartphone forums, my phone made strange problems. I found out that I had published my real IMEI (in a picture or file), somebody abused it with a stolen phone, and I was punished for helping. Since then, I know why images or pictures contains wrong or missing IMEIs
The solution is simple: Download the latest version of SN write tool https://snwritetool.com/category/download, look at the instructions on https://androidmtk.com/use-sn-write-tool and write the correct IMEIs in your phone.
With the MT6739 chipset you will have problems to choose the correct MD1_DB file, but when you activate the options "Load AP DB from DUT" and "Load Modem DB from DUT" you will be successful.
