I was trying to backup the stock ROM of this tablet (Blackview Tab 8) however i must have incorrectly installed SPD drivers or somehow had uninstalled them, because Research Download said "failed user cancel", then boom when i tried to switch it on it was not turning on nor charging. I have been trying to charge it for about 4 days, no dice, it does not charge still, nor turning on.
This Tablet is sc9863a
I must have soft bricked it, because it gets detected by the PC as "SPRD U2S Diag (COM5)", but when i try to flash Stock ROM i downloaded it either says " failed user cancel" or gets stuck at "checking baudrate".
I don't know what to do, would opening it and test point it make a difference? Even if i open it intending to test point it, what pins would i have to click on the board? Because some guy on Youtube was able to flash his SPD phone after test pointing it, as it was facing "failed user cancel" . Since board are of different models so i think pins to be test pointed would be different.
I wondering if someone with the exact Tablet has ever faced a similar issue, or am i using the correct key combinations. Because i use vol - then insert the cable. Even if i change and use vol+ or both of them with and without power button, it doesn't flash on Research Download.
