Charge Phone Before Flashing

It’s not sacred knowledge that your smartphone needs to have a fully charged battery in order to boot up the firmware. Since the first boot after flashing a custom ROM or stick firmware needs at least 10-15 minutes of setup time, it’s better to charge the phone battery to at least 50 %.

In case you don’t have visibility on how much battery % is there in your device, it’s better to keep it on charging for 1 hour to be on the safe side. Once you have charged your smartphone, you can try to flash it with the SP flash tool.

Method 2: Keep Your Phone Connected

If you have a dead phone on your hand that does not turn on after flashing, leave it connected to the computer for a while.

So in order to make them compatible, you have to use any OPF extractor that can extract the required firmware files to flash on your device. However, many third-party OPF extractors are outdated and not compatible with the newest OPF files. Our recommendation is to use MABT (also known as MTK Auth Bypass Tool) to extract OPF files in the correct format.
