You have use power + volume up key to access preloader menu and you can select bootloader from there ,once you flash factory preloaderHi folks,
I have just unlocked my Redmi Note 8 Pro and I want to move onto the next stage of flashing preloader_begonia.bin and lk.img, but I can't get fastboot to work.
I can get fastboot to recognize the device with fastboot devices, but all other fastboot commands either hang or give an error.
Others online with the same problem said that they were using an old version of fastboot, and updating it fixed the problem, but I'm using the one from this thread which is the latest version.
Does anyone know if there is a fix for this problem? Or maybe someone knows something I can try?
(I'm using Win 7)
EDIT: OK! This tool works for me. Nothing I did before worked but installing this version of ADB/Fastboot allows me to actually use Fastboot.
All praise and All Thanks to God ADB Fastboot and USB Driver installer tool for Windows, which will always install the latest version. To update the adb fastboot and usb drivers again, just rerun the tool. OS Requirements: Windows 7 and Above...forum.xda-developers.com
