[Redmi 9A ROMs, Kernels, Recoveries, & Other Develo] jdd1996:
Lineage -- what can we say, this word refers to Ancestry , its a more Open Sourced frame, based on AOSP but now has another theme, its ungoogled as much as possible, adapts to different CPU's, Kernels.

Lineage 19.1 release is based on Android 12.1 , i give it a 4.7/5 in smoothness and performance on the 9A That's why i want to share it here.

Everything works, no NFC, but the rest works perfectly. Including Camera , Recovery, everything.

Lineage OS 19.1 - Android 12.1-- 2023 August Security Patch

https://sourceforge.net/projects/an...1-20230715-UNOFFICIAL-a64_bvN.img.xz/download - Vanilla (Recommended)

Another ROM i want to share ( bluetooth and magisk do not work)

AOSP-TrebleDroid - Android 13 -- 2023 July Security Patch

https://github.com/TrebleDroid/treb...06/system-td-arm32_binder64-ab-vanilla.img.xz - Vanilla

Incredible ROM, fastest, smoothest experiences i've had. The problems are the above mentioned, no bluetooth and no magisk yet for this device - Performance/Smoothness = 4.9/5

Sources - https://github.com/TrebleDroid/treble_experimentations/releases

Method of install, requires a PC and ADB, Bootloader unlocked;

1 - First install MIUI 12.0.19.0 -- I haven't tried with 12.5.4.0.

(I think coming from any Android 10 will give it a smooth performance.)

2- Unpack desired GSI, rename the file to "system.img"

2 -Reboot phone into recovery - format/wipe all internal data (dalvik , cache, data, internal storage)

3- Reboot phone into fastboot (also called Fastbootd )

4- Plug phone, open terminal and work with fastboot-adb (android sdk platform tools) execute commands;

fastboot devices (make sure its being recognized)

fastboot flash system system.img

(allow it to complete flash very quickly in 2-5 mins, im impressed with how fast it transfers)

fastboot reboot recovery (reboot to recovery and format/wipe all internal data again)

5- finally reboot to system.

These roms will boot very quickly after the redmi Logo, just wait a few mins, and you should be in.

Personal Opinion:

-- I will stick with Lineage OS 19.1 for the time being. Because it has excellent battery life, acceptable performance and bluetooth works.

But AOSP - TrebleDroid wins in performance and battery life with 5/5 score for me, but has no magisk or bluetooth which is a downside when playing emulator games, connecting gamepad or headphones.

I realized its not good to be flashing stuff all the time, everything has a life time. Even Internal Storages/Memory RAM... So becareful not to overdo it with the ROM flashing thing, its not a sport. We should give Honest REVIEW of our experiences with ROMS, so that others can benefit without wasting time, experiencing lag or issues.

None of these Roms bricked my phone , so they're very safe, Use good cable and good 2.0 USB upwards.

This is as updated as we can be.

At this point i realize we cannot offer more to this device, for more, purchasing a new/better device is the recommended approach. We start to realize this when in Android 13, Bluetooth or Magisk are broke. So we still have to wait for many developments and updates before rushing to flash new Android versions.

Android 14 is soon to be released next year, and hopefully Linux OS will continue developing itself for ARM-ARM64 cpu's

Keep your security up to date.

Look foward to healthy tecnology, convergence and adaptability.

Remain updated and stay positive safe.
