Is is possible to use the last Android 9.0 firmware release to flash on a P60 version of BV9600 Pro?

Sorry, no.

It's still a shame because the announcement at the launch of the BV9600pro in nov 2018 announced this update to android 9. In all, it was planned in the many ads and on the site of blackview. Beware of ambiguous ads.

It seems we've been scammed

As a result, there will be no update for the P60 release in the future?

On the Russian forum 4pda, I personally posted the installation instructions for android_9 on the revision with the P60 processor
Naturally, this is not an official installation method, but at least I’ve been using android_9 for a month on my bv9600Pro (p60)
absolutely everything works, even contactless payment ..
Officially, on the old revisions, android_9 will never appear .. otherwise, who will buy the new revisions !?
I also want to remind everyone that in no case do not install android_9 on old revisions if you have no experience using the flasher ... otherwise you will overwrite the nvram block. A lot of users lost nvram when trying to install android_9 ...
Restoring nvram is much harder than wiping, especially when there is no personal backup

in order for everything to work on old revisions, you must strictly adhere to the instructions for installing the software (the instruction is not simple, you need to unlock the bootloader and there are still nuances ....) otherwise, at least the mobile network will not work (because the revisions differ in modem) !
Unfortunately I can not write instructions in English, because I do not know this language

quick installation guide for android_9 on bv9600Pro / revision_1 (helio P60):

download software: https://mega.nz/#!5Y8FyKLS!o6t3colH9_4ieauO_4_tN9NtsDB4G8zBF-c1FdhmtnQ
install using SP_Flash_Tool in "firmware / upgrade" mode ( necessarily mode select "firmware / upgrade" otherwise you’ll lose nvram)
after installing the software, disconnect the cable from the smartphone but do not turn it on
in SP_Flash_Tool we charge "MT6771_Android_scatter.txt" which is located in the "Fix_start" folder (this folder is in the root of the main folder)
Flashing the "preloader" block in the normal "Download Only" mode
Only after that we turn on the smartphone and rejoice android_9, on which everything works on helio P60/revision_1
The only inconvenience awaits you is the red characters in the upper corner of the screen
To remove them you need to unlock the bootloader! After unlocking, the hieroglyphs will disappear automatically!
If you do not understand what I wrote, then do nothing with your smartphone! all actions are strictly at your own peril and risk!

It’s difficult for me to write instructions for unlocking the bootloader, so I don’t even dare to do it! .. but the instruction is standard for android_9, you can peek at any topic on xda

Do you have a download link for the original P60 stock ROM, especially the scatter file?
It should be a good idea to save the P60 version about a full read back. After this exist a copy of nvram partition.
What is the reason for the second reflash of preloader?

It seems to me that in this thread so no one fully understood about the number of revisions !? company representatives also do not want to clearly explain everything ..
I will try to explain the situation:  At the moment, the bv9600Pro smartphone is available in three revisions
revision 1): bv9600Pro (P60 / "mt6771v/c") android_8.1
revision 2): bv9600Pro (P60 / "mt6771v/c") android_9.0
revision 3): bv9600Pro (P70 / "mt6771t") android_9.0
The software between the first and second revisions is 98% compatible. The only difference is in the modem! (Mobile connection)
Therefore, installing software not from its revision, mobile communications will not work! everything else works!
The third revision appeared recently and official firmware is not yet available for free!
if I made a mistake somewhere in the description, let the moderators (official representatives) correct me
