Apps started crashing - did factory reset - no boot

Hi,

I have a 3 week old BV6000. (No serial number anywhere I can see..)

It had Nougat on it when I got it.

No adware, and I was running Avast Mobile Security and Malwarebytes Anti-Malware.

I have not used the phone in water or done anything outside of normal use as a phone.

Last night the applications started crashing (Application crashed. Restart or send feedback).

Choosing Restart just gave another crash.

First it was Avast, then more and more apps crashed.

I rebooted the phone and it seemed ok for a few minutes before it all started again.

"Google Services has crashed. Restart?" came up and the screen went black.

Restarted again and went straight to Settings -> Backup and Recovery -> Factory Reset and did a factory reset.

Phone rebooted, and is now stuck on rebooting.

Shows the Blackview logo, then it goes away, and a few seconds later it shows up again.
Goes on like this until the battery runs out or I turn off the phone.

I cannot boot to recovery.

Any tips?

Thanks.

Update:

I managed to push Android 6.0 version 2016.10.25 using ADB and Fastboot.

Device booted successfully, but both IMEI were just 111111111111111.
Tried several tools to set the IMEI's, including the MediaTEK tools.
None works, all fail with "invalid database entry".
Last program I tried this morning was the MobileUncle ToolHero.

It allowed me to type in the IMEI1 and IMEI2 and asked to reboot.

After rebooting the IMEI was a random string of numbers totalling 27.

I downloaded Android 7 Nougat 2016.12.16 and tried to flash it using TWRP as the flashtool did not work.
When trying to flash it I get these error messages: Click to see the picture of error messages.

Really strange problem, looks almost like the firmware has been corrupted somehow.

Third flash (full 100% battery charge this time) did the trick.

Back on Android Nougat 7.0 2016.12.16 and both IMEI are now proper and phone is working again.

Not sure how this happened.

Have now rooted the phone and installed TWRP so I hopefully can avoid this issue in the future.

As another user posted: This phone is a great learning tool for getting to know about the MTK peculiarities and flash tools, etc.
