What is the difference between those firmwares?

Hello.
I want to flash latest firmware, running Syberia ROM, but I want to know what are the differences between: FW, FW-less and FW-non-arb?
Thanks.

If you are still anti rollback (arb) 3, installing the latest firmware (FW) will update your bootloader, thus you will have arb 4.
Fw less roms come without the firmware. since there is no firmware, no way to trigger ARB.
Fw-non-arb are firmware files without the bootloader part, again no bootloader so arb will not be triggered.

I have a Redmi Note 5 China with MIUI 9.6.4.0 stable, I want to install some custom rom, liquid remix or havoc, I will download the latest firmware ''MIUI 10 8.12.27 Global / China Beta ROM Firmware'' but I do not know which one do I do? ! FW, FW-less or FW-non-arb?

Since 8.12.27 is the newest rom available you can install only FW as this would not trigger ARB (Both 9.6.4.0 and 8.12.27 are ARB4)

Unable to flash roms which need pie firmware

Flashing latest builds of most ROMs (ones which need pie firmware) give error 7: with message 'you need to have firmware V10.3.1.PIEMIXM or above as prerequisite to flash this rom'
Since I am on anti-rollback-3, i downloaded and flashed the non-arb version of V10.3.1.PIEMIXM firmware from the stable firmware list, but flashing the rom still gives the same error.
I tried using TWRP 3.3.1 Official, i am using redmi note 5 pro (indian version). Can anyone tell me what am i doing wrong?

Just install the normal fully arb firmware and try again

Is there no way to get pie firmware without getting to anti 4?

You need recovery compatible with Pie FW. Here is unofficial TWRP 3.3.1-1 working fine with Pie FW.

Firmware files

Just out of curiosity, I have a couple of questions regarding firmware files. I'll keep it simple.
How can I flash them from a PC, i.e, without any custom recovery?
Can I flash a new firmware over an old ROM? E.g MIUI 12 china firmware on MIUI 11 global?

Is it possible to downgrade the Android version to a custom ROM?

I am unlocking the bootloder on my mobile Android 9 miui 11.3, I want to run Xiaomi eu's Android 8.1 miui 9 custom rom now. Do I need any frimwear to install custom ROM on this device?

I think Eu ROM flashes the firmware automatically, so u don't need to flash firmware by yourself.
But but but please check the ARB version of firmware

Question What is firmwire

So i have this mi 11 lite device (lisa) and when i was flashing awoken os rom after flashing i was sidedload the firmware i downloaded from Xiaomi website..but after flashing it only went to bootloop but when i flashed pixel os rom and downloaded their firmware that was included with the rom it worked !! So my question is can i use that firmware for every rom or do i have to download separate firmware for every other custom rom..or is it the Android version that requires the same version firmware... e.g Android 12 has one firmware that works for every Android 12 rom and Android 13 has a firmware that works with every Android 13 rom..

Every rom requires different firmware . U can download the proper one from the rom's topics
