BV4900 Pro black screen after systemupdate
(12-02-2023, 02:52 PM)WalZe08 Or maybe I could try with Miracle-Box?
Should the battery to be charged in this case?
How should I go on?
At first (over)write preloader and then it will be possible to "communicate" to smartphone also with other tools?

Try just sp flash tool but this time around:
1. Try a different USB cable, port or different PC (if possible)
2. Don't hold any button when you connect
3. Untick all except preloader then flash using Download Only
Share a full screenshot of SP flash tool if you still get an error

I got this message:
" CPU: MT6765 SW:0000 Ver: CA00
Downloading Boot8 ...
>>The Boot not support the Phone, or CPU Bad. Select other Boot."
I think, the model BV4900 Pro is not known in this version and it could be possible to reach the phone with a current version. Is it so?
(04-03-2023, 10:33 AM)WalZe08 Yes, I did.
(10-03-2023, 02:32 PM)WalZe08 I have the factory firmware, but I cannot flash nothing! Could somebody show me the test point by this smartphone?
