Download Oppo A57 Cph2387 Preloader File To Avoid Jumping To Brom Message From Some of The GSM Unlock Tool.
I have a preloader file that may help you with the Oppo A57 4G 2022 CPH2387 jumping to Brom issue.
Some of them suggest using the "test point" method to fix the Brom error. That's why I gave you a test point with this file.
while others claim that you can use a tool like "CM2" to flash the device without a test point.
Please be careful and follow the instructions carefully, as this may damage your device if done incorrectly.
