Now choose any rom from here, than download the compatible variant as you see in treble info app.

The file you are going tlo download will be in ".xz" file extension, you must exract it using 7zip.

Than connect your phone to pc and run this command;
(i will give 2 command, i not remember which one is right, try both)

adb reboot fastboot
or
adb reboot bootloader

once you done, your device must restarted in recovery gui, and it detected as fastboot device in windows. (if not, you must install google usb driver in device manager manually, or try 2. adb command)

Now you can flash gsi rom with this command;
fastboot flash system <gsi_system_image>

you also must flash empty vbmeta by this command;
fastboot flash vbmeta_system <empty_vbmeta_image>

If you have more question or have trouble kindly reply to the post or find me on telegram (MrMiy4mo)

@Sam_cheat the steps are same as above since this is GSI

There are few exception, but not here.

@MrMiyamo Sorry I have a problem, when I try to flash it says fastboot locked, i tried unlocking with mtkclient but when Install the gadget mediatek driver it doesn't detect the phone, any solutions? I searched on forum but I don't find anything to fix this

so how I unlock? Im quite lost, and the apk deeptest also don't work
Earlier, i was able to unlock bootloader via common method.
Which is to check "oem unlock" on developer options and entering to fastboot mode (by rebooting to fastboot mode from recovery mode, took me long time to find that way, i even used mtkclient at first).

This way may or may not work with C21Y, you may talk with other members here who have a C21Y

Я хочу прошить кастомную ОС gsi на моем realme C21Y, но мне нужно кастомное рекавери, если оно у вас есть или вы знаете, как это сделать без кастомного рекавери, я был бы признателен

можно обойтись без кастомного рекавери и полной перепрошивки systems с загрузчиком gsu в разделе для разработчиков, только для этого нужен разблокированный загрузчик
