Installation guide
First we have to extract recovery.img from the file “e-3.x.x-x-202x000000-UNOFFICIAL-cannon.zip” whatever version we just downloaded, once recovery.img is extracted we flash it with fastboot using fastboot flash recovery, once thats completed we do fastboot reboot and hold the volume up button to boot into the e/os recovery.
Once we boot into recovery we simply have to select factory reset then format data then format system partition, once thats complete we select the arrow on the top left to go back and then apply update either with adb sideload or sdcard.
Note: the 3.1.4-t build gives a verification failed install anyway? warning just select yes
MicroG version for this build is 0.3.9

Revolut :cross_mark: build.prop tweak is not enough as bootloader unlocked status is visible
Wizz air :cross_mark: closes as soon as you open it, likely bootloader unlocked detection or needs buuld.prop tweak

Hi all,

I am currently using the Redmi Note 9 5G (cannon) with the Dimensity 800U (8/256GB). I am planning to move to a custom ROM (specifically looking at crDroid or LineageOS), but I have a specific requirement.

My question for anyone already on a custom ROM:
Does your ROM bundle newer vendor blobs that bump the reported apiVersion to 1.2 or 1.3? Or is the ROM still using the legacy Xiaomi 1.1 blobs?

If you could run vulkaninfo in Termux or check VulkanCapsViewer, please let me know what version is reported.

Device Info:

  • Model: Redmi Note 9 5G / 9T

  • Codename: cannon

  • SoC: Dimensity 800U (MT6853)

Thanks in advance for helping me avoid a “blind” flash!
