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.

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)

Do I need to update firmware before flashing custom rom?

I am currently on MIUI Global 9.5.19.0. Do I need to flash the latest firmware before installing an android 9 or 10 custom rom?

Yes buddy u have to flash atleast a pie firmware
(I suggest to flash 9.4.25 firmware, as it is best Pie Firmware)
U can download from Xiaomi firmware updater

Thanks man!!

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 How to update to 12.5.9 ?

Hello,
My lisa came with 12.5.5 out of the box. OTA offers direct to 13.0.2. Is there anyway I can upgrade to 12.5.9 ? I don't want to upgrade to A12 atm, or anytime soon really.
Indian firware if that matters.
I see xiaomi.eu has a version of 12.5.9 which is no longer updated, but lisa isn't listed on the compatible device list.
Thanks

First of all, some basics (not sure are you aware of):
1) If your phone came with Indian, you can update but only to Indian firmware without unlocking your Bootloader:
Install MIUI Recovery ROM using Stock Recovery and Updater App
Has your Xiaomi phone received a new MIUI update? Then follow this guide to easily install MIUI Recovery ROM using stock recovery and Updater app on Xiaomi devices. Any smartphone user prefers getting…
www.thecustomdroid.com
In that case you will need to download the so-called Recovery or ZIP stock firmware and use the installation as above
2) For anything else, like switching from Indian to Global or EEA (or to Russian or Chinese) - they are all stock ROMs, or switching to Xiaomi.eu - that is not stock ROM, or any other custom (ie, not stock) ROM, you would first have to unlock Bootloader
AFAIK, Xiaomi.eu has no 12.5 for Lisa, only 13.0 - hence not applicable if you insist on 12.5
To switch from Indian to Global or EEA (still stock ROMs), you will need the unlocked Bootloader, the so-called Fastboot or TGZ firmware (and MiFlash tool):
How to Flash Fastboot ROMs on Xiaomi? - xiaomiui
If you are a Xiaomi user and have installed custom ROMs on your device, then you might be wondering how to flash fastboot ROMs on Xiaomi devices. This article

I don't know where do you see 12.5.9 for Lisa - I had 12.5.8 EEA) , but there should be not much difference
Anyway, install the following app and you can check which versions are available for Lisa (for stock Global, EEA, Indian, etc) or custom Xiaomi.eu:
MIUI Downloader - Apps on Google Play
MIUI upgrade app for Mi users.
play.google.com
It shows the Latest but click on Older and you will see all the previously released (stable) versions.
Btw, under Indian, I don't find 12.5.9, neither under Global or EEA (under Global there are eg 12.5.11 and 12.5.14)
From the app, you can also choose and download Recovery (zip) or Fastboot (tgz) stock ROM for the wanted version - depending on your flashing method as above

thank you very much. I did request to unlock the bootloader in the mi unlock app, but all the custom A11 roms stopped development or moved onto A12, so I didn't see much point in unlocking bootloader.
as i understand, if i am on the indian firmware, i can flash the indian rom without BL unlock. but if BL is unlocked, do i need to switch firmware as well to install say the Global ROM ?
about 12.5.9, i mistook it as the last version before they moved to 13. sorry about that.

When you unlock Bootloader it does not prevent you to update India ROM by stock Recovery method
It just gives you the additional option to switch eg to Global by flashing Fastboot/tgz ROM
Its like, you can always go by foot, but if you have a car, you have the additional option to go by car
Please take your time, Google, read to acquire further knowledge and know-how.
There are tons of guides here on XDA, on the Net, Google videos, etc

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
