@Blackview-admin: could you please post a link in the manual for the correct SPflash-tool version and VCOM-drivers. Can't get update working on Win-XP and WIN7.

can't get it working on WinXP-32bit (VCOM driver INF-file for XP dated 05/30/2011, version 1.1123.0) and neither on WIn7-64bit.

Used SP-flashtool for MT65xx Preloader - version 2017/04/27 12:31

Get error S_BROM_DOWNLOAD_DA_FAIL (2004) indicating communication problem due to cable or hardware.
- Replaced USB-cable by another Blackview backup cable.
- Battery fully loaded at 100%
- Bootloader NOT unlocked
- USB-debugging on
- USBDEVIEW checked if any other driver makes problem.
See picture in low-resolution; note that standard USB-masstorage function allow reading / writing from PC to BV7000 thus USB-cables should be oke, inclusive port-connectors!!!!!!

Question: is the flashtool MT65xx also suitable for the CPU MT6737T of the BV7000-standard?

EDIT: Blackview BV7000 after next try on other USB-port initially same error as above but next try on this USB-port BV7000 totally bricked.
Red-LED keeps on burning while no loading is ongoing. Long pressing power button and nothing happens anymore. What to do???

No answer from Blackview_admin, so i decided to open the case and disconnect the battery to reset the somehow-looping-flash-program in the BV7000. That did the trick but note: opening the case with T5-torx and small PH00-screwdriver is not everybodies job! I made the error to put one small T5-screw at the position where a long t5-screw should be and broke the tread in the case partly. Thus pay attention to put TWO a bit larger T5-screws at the correct position beside the camera lens. See image and the two red arrows!!

Thus i'm still looking for the correct version of drivers + flashtool to do the job without bricking my BV7000!!

I received my testing device and like promised I am trying to reproduce your issue.
Until now stong pressing the power button for minutes(!) always helped to start a phone that looked like bricked.

But we also will investigate the flashing-issue and I will inform you as soon I know something new.

Hi PietK. There can be multiple reasons that flashing don't work for you. Please try the following:
- check that Phone is charged more than 70%
- download USBDeview http://www.nirsoft.net/utils/usb_devices_view.html Use it to uninstall all MediaTek drivers that have been installed before.
- Install MediaTek MT67xx USB VCOM drivers https://drive.google.com/open?id=0Bziqh ... GEwbXRhb1E
- Start windows device manager
- turn off phone and connect to PC with the original USB cable
- check that the phone is recognised correct (under "connections COM&LPT" as "Preloader USB VCOM Port") only in the first few seconds of connection .if it is recognised not correct click that wrong entry with right mouse button + click attributes (you have to be very fast in the first seconds after connecting) click "Update driver" > search on PC > choose from list > show all devices > choose "Preloader USB VCOM Port"
- try to flash. if SP flash tool still don't work try SP MDT 3.17 http://spmdttool.com/sp-mdt-v3-1708-00 (Tutorial https://androidmtk.com/use-sp-multiport-download-tool )
- If you still have problems repeat with other usb ports (check correct driver again), other cable or other windows pc

-Please report if you managed to flash with this instructions

PS: I never needed to do this for myself but other users reported that they needed to press the volume+ key while plugging the device to USB.
