What is a brick?

If there is no usual way to recover your mobile, then it is called brick in my opinion. That means if you can't able to go to recovery and fastboot mode or the device is just blank with no sign of life.

When brick happens?

It will happen because of locking bootloader with custom images or just because of Mediatek/Realme strange behaviour.

What we have to do if brick happens?

Simply we have to flash stock firmware with Smart Phone Flash Tool(aka SPFlash Tool). With only SPFlash Tool we can't do anything, since we don't have permission for it. But with the advent of MTK-bypass, we can have full control over our device. If we don't have this MTK-bypass, then we have search for costly alternative's.
You can't flash only if your eMMC is damaged, which is the worst case because oppo phones are prone to eMMC failure.

Where to get firmware to flash?

Download decrypted .ofp firmware from https://drive.google.com/file/d/1SOmRxix9_UtjOLLanXPYxf4YK1NrA_RW/view
Thanks to @bx2_nero for it.

What is the procedure for using MTK-bypass and SPFlashTool?

MTK-bypass is a Python script and it needs different USB ways for working. So with these two in place, we can get our work done.

Linux Users

For Linux we have to use FireISO or patched kernels for working of MTK-bypass.
Use the Linux guide by @bx2_nero at https://forum.xda-developers.com/t/...our-realme-6-6i-india-6s-linux-method.4251077

Windows Users

For Windows we have to use libusb32 filter for MTK-bypass working.
Use the guide by @daeSundae at https://forum.xda-developers.com/t/...india-6s-using-spflash-tool-for-free.4222027/

MTK-bypass Official instructions

See Github ReadMe at https://github.com/MTK-bypass/bypass_utility and XDA support thread at https://forum.xda-developers.com/t/mod-dev-mediatek-mtk-auth-bypass-sla-daa-utility.4232377/

I need help, my C12 is stuck on fastboot mode. This happened after flashing a GSI using TWRP and flashing the image in the Super (System and Vendor) partition.

I tried rebooting to recovery mode by executing fastboot reboot recovery but it says that bootloader is not known.

I also tried to flash a GSI (taught it might fix the problem) using fastboot flash system system.img but it says that no partition named system exists.

Please suggest what I should do.

Bro, can you make a video about this? my realme c12 got hardbricked after I flashed ozip file from stock recovery while bootloader is unlocked. it got hardbricked when I reboot it after flashing ozip
 
How can I reboot to recovery mode when in fastboot mode? The command fastboot reboot recovery is not working for me.

Use latest platform tools
Sir I've finally able to reboot to recovery. I've tried flashing the OZIP file for my model but after some time it says Installation failed. When I was still using custom recovery, I wasn't able to mount System and Vendor. My bootloader is also unlocked sir.

Should I lock my bootloader sir?

Don't lock bootloader.
Download this https://sourceforge.net/projects/realmec11/files/Fastboot-ROM/[email protected]/download

Extract above 7z file and flash ONLY super partition from it with below commands
Code:
fastboot -w
fastboot flash super super.img
fastboot flash recovery stock-recovery.img
fastboot reboot recovery
Now flash stock ROM .ozip in stock recovery.

Thanks
Oh my, thank you so much sir. You have no idea how much you are helping me sir! My parents will be so happy, and we won't waste money… Thank you so much sir… 😢

I'll update you sir after doing these, thank you sir! ♥

Download this https://sourceforge.net/projects/realmec11/files/Fastboot-ROM/[email protected]/download

    I rooted My Device (Realme X2 Pro) by Magisk. And Since My Device Bootloader was unlocked I Unrooted/Uninstalled MAgisk.
    While Locking Bootloader My Device is Stuck where It displays { The Current Image (boot/recovery) have been destroyed dand cannot boot. Please flash the correct Image or Contact Customer Service to fix it }
    While Trying to ENter the Fast Boot Mode {By pressing Volume + - and Power Button} Its Unresponsive
    It shows Realme Logo And chrging Display for a Instant

    Do you Know any way around to fix my Problem?

    Since your device is Qualcomm, I don't know. In any device, we have to flash stock rom (or atleast the partitions that are modified) to get device in working state.

    You may get better help at https://forum.xda-developers.com/f/realme-x2-pro-questions-answers.9439/

    Thanks
