First of all, you should first check what anti you are on. You do that by launching CMD from ADB tools and typing command "fastboot getvar anti". If it shows 3 then ARP protection is not turned on. But if it shows 4, then it is turned on, and that means that you can't flash any rom containing firmware of anti 3 because your device will be bricked. If your anti is 3 then you can flash any rom you want whether it is anti 3 or 4, but you should really be careful with the ROMs you flash(especially miui based) so you don't enable ARP. Your ROMs should not include firmware files. Masik for example doesn't, so it's safe. For the other ROMs you should search and ask to find out whether they are safe or not.

ok sir ... it means that i can install miui custom rom without the firmware inside, with the note that the above version might be like that?

Basic Answers to Flashing procedure

Hey guys, I am new to whyred , flashed alot on other phones tho. Got some questions regarding the process of things I have to do to not mess up. I would do it like this:
0. I am on 9.5.19. miui global stable.
1. Unlock bootloader after 360 hours (hopefully)
2. Boot into Fastboot, boot up twrp image via command and then flash twrp via twrp.
3. Do I have to flash lazyflasher when I flash magisk? Which version of magisk is recommended atm? 1600?
4. After flashing one (or both, I don't know) I would go with flashing aosip or havoc (which is better on battery, features and over all performance?).
5. Do I have to flash some firmware or anything?
6. Since I am on Anti 4 (probably, didn't check yet but I am quite sure since I updated on 9.5.19) do I have to be aware of something else important?
Thank you guys for every help. If my answers will get answered and everything runs smooth sailing I will write a noob/starting guide to focus the knowledge a bit more. It seems really clustered in this forum
Do not flash any firmware for now. Since your are in 9.5.19 it has anti 4 enabled.. flashing firmware over anti 4 will brick your device.
Unlock bootloader
Boot to twrp and flash twrp
Wipe system cache dataa and flash custom ROM and gapps
Reboot to system
Reboot to twrp and flash magisk

I still at 9.2.13 didn't update to 9.5.19 in that case I can flash and roll back to any firmware below antilock right?

Yes. If you are in 9.2.13 build then you have to flash firmware along with custom ROM.
But if you are running 9.5.19 build do not flash any firmware. Just ROM and gapps is enough

Which firmware are you referring to? You mean I can roll back or do I have update to certain firmware to flash custom Roms?

Yes you have to flash firmware file recommended by custom rom developer to avoid problems while using custom ROM. And its not related to anti rollback protection.
All the firmware recommended by developers doesnt have anti rollback protection but you shouldn't flash firmware file if you are using 9.5.19 stable build or 8.7.12 beta build because these build contains ARP and flashing firmware in ARP enabled device will brick your mobile

I'm a bit confused here. I have always been under the impression that firmware = ROM (with other phone brands) and they seem to be discussed interchangeably. Now with my Xiaomi Note 5 Pro, I hear about these as separate items a lot. What is the difference between firmware and the custom ROM, at least in the Xiaomi world? How do I know when I am dealing with one or the other?
TIA,

Your understanding is correct firmware is nothing but a ROM, but in custom ROM, developers dont include bootloader (In custom ROM world firmware contains bootloader related stuffs) in their OS because they will make use of bootloader from stock ROM thats why developer recommended firmware files so that their ROM works perfectly without any problem.
I might be wrong but this is how things work here. If you are on lastest global MIUI beta ROM then you dont have to flash recommended firmware file by custom ROM developer

So when people talk about flashing firmware, they're really saying to flash/change the bootloader? Does the bootloader have a name, version number we would reference, or it's just 'the bootloader for MIUI Global 9..5.19.0'?
If I understand you correctly, if someone offers a ROM with and without firmware, you could install the ROM without firmware and it would work ok, but installing with the firmware (changing the bootloader) would make the ROM work better? Or just do the ROM with firmware if you have problems with the version that didn't install the firmware/bootloader?
I'm on MIUI Global 9.5.19.0. (just normal ROM), but with unlocked bootloader, twrp, Magisk installed (I can't work without my Titanium Backup Pro!)

Most of the firmware recommended by developers contains older bootloader (Antirollback protection version 3)
Since you are in 9.5.19 your bootloader has Antirollback protection (ARP 4) so if you try to flash older firmware then your mobile will get bricked so avoid flashing any firmware recommended by developer because you already have latest bootloader
Firmware name will be based on global beta ROM version

Need some advices please

Hi all,
I'm trying to flash the global ROM on my Whyred. However, it's currently already on the latest MIUI 10.0.0.1 (OEICNFH). I've confirmed it has anti rollback (4) enabled already.
What's my best move right now? Do I unlock the bootloader and then... ?
Or do I wait for the latest global 10.0.0.1 and flash that via fastboot? Not too sure what to do now.
Or can I simply flash the latest MIUI 10 8.8.30 beta via MIUI recovery - http://bigota.d.miui.com/8.8.30/miui_HMNote5HMNote5ProGlobal_8.8.30_4996e76420_8.1.zip
You. Cannot flash global ROM using updater app but you can flash miui10 global beta using fastboot method
Before flashing miui10 global beta just confirm antirollback version in miui10.0.0.1
If it is anti: 4 then you can flash all ROMs (including stable) which has anti version 4
Thanks for your reply! I'm on anti 4 atm.
I need to unlock bootloader before I can flash using fastboot right?
And looks like you can use fastboot flash commands in CMD, or use MiFlash (which also uses the fastboot ROM). I presume both requires an unlocked bootloader either way?
Yes you have to unlock bootloader to flash fastboot ROM
Thanks, I know how to do that
Just to confirm, even though the MIUI 10 Global beta is v8.8.30, which is a lower version than the MIUI 10 Chinese Stable 10.0.0.1, it's still OK to flash? They both came out on August 30th, so I'm assuming it's OK to flash from one to another and vice versa, without getting the phone bricked?
https://www.theandroidsoul.com/xiaomi-redmi-note-5-pro-update/
enter this commands
fastboot getvar anti
to know the antirollabck version, if it is anti 4 in MIUI10.0.0.1 then you can flash MIUI 8.8.30
Yup it's anti 4.
I thought the anti rollback prevents you from "downgrading" to a lower firmware? I'm a bit confused why stable 10.0.0.1 can be upgraded to 8.8.30 beta, even though the version seems to be lower. I guess it's just a naming convention difference for the stable and beta firmwares?
Then you can switch between any anti 4 ROMs
Yes beta ROM naming convention follows present date month year format
8.8.30 indicates
2018/08/30
Next beta update name will be 8.9.6
And yes antirollback prevents you from downgrading to older version of bootloader
9.5.17 ROM and previous ROM has anti3 so you cannot rollback to those version
For China stable it is 9.5.21 and you cannot rollback to 8.5.6 beta ROM these ROM
So be careful while flashing older version this may brick your device and no problem while downgrading anti4 enabled ROM
Perfect, that makes a lot of sense now.
Thank you very much!

ARB and custom ROMs

hi! I'm having problems with wi-fi and mobile connection and I am on a custom ROM at the moment
my question is:
if I flash **complete** MIUI ROM (latest 10.0) without locking the phone using Xiaomi tool, would I still be able to install TWRP and custom ROMs without bricking the phone?
I am not interested in previous versions of MIUI so obviously I wouldn't be downgrading MIUI versions
Yes you can, remember that custom ROM not have firmware so your arb status will not be touched

yes use fastboot rom and miflash to get back to miui 10. thats ARB4. remeber to tick clean all in miflash dont relock bootloader. and then you can install twrp and any custom roms.

Need help in downgrading

I have redmi note 5 pro and I have installed the latest orange fox recovery in it. Please tell me how can i downgrade my miui 11.0.3.0 to miui 10.2.1.0 oreo without bricking my device.
Thanks in advance
I'm not sure (wait for a proper answer) but I think ROMs from MIUI 9.5.19.0 and above are ARB4. I recommend that you flash a fastboot ROM that include the proper firmware for Oreo.
Fastboot ROMs: https://xiaomifirmwareupdater.com/archive/miui/whyred/
yes I recomend fastboot way too, not recovery's
I will like to ask people why recovery downgrading is risky as with custom recovery u can have n number of possibilities

Thanks buddy for ur help, I successfully downgraded to 10.2.1.0.
One more question,what is the minimum ROM version that i can downgrade to (I have ARB 4)?
Now your ARB version is 4.
You can download the offical ROM image package and exract it.
Then open the file called "flash_all.bat". Look for "set CURRENT_ANTI_VER" in this file and look at the ARB version of the package.
If the anti level is 4 , it's safe to downgrade to this version.
If it's below 4, DO NOT flash the ROM or your phone will be bricked.

Question Any way to flash stock ROM if my phone is on "anti:1"

All the stock MIUI rom available have an anti-rollback lv 0. Am I basically SOL until Xiaomi releases a rom that is anti-rollback lv 1 or is there a workaround? My phone is the global version if that helps.

I think I have the same phone as you do. My last lifeline was to try and flash the Pixel boot.img and see if that would at least get me recovery. No luck. Not really sure what to do at this point, but I think that it's the anti-rollback that may be causing a problem for me as well - just not sure what else is on there that could prevent it from accepting and booting a flash recovery. None that I've tried (lineage, pixel, orange, or twrp) work.
I think I'm just going to set the phone aside for a few months and hope that something develops in the meantime. Right now the phone is stuck in fastboot and is still a recognized device. I'd hate to blackscreen it by experimenting.
Just an aside, at this point I'd be very cautious about trying to flash a custom ROM to any handset that's been OTA upgraded to Android 12/Miui 13.
I gave it one last try using zgfg's recommendation here:
Bootloop Fastboot (stock) / Phone locked for security reason (Xiaomi.eu)
Xiaomi 11 Lite 5G NE (Lisa) Stock 12.5.8 EEA Bootloader unlocked, Orange Fox recovery and Magisk Canary 25.2 I was running the same set-up for a couple of months, by only updating when newer Magisk was released or some module. I never had any...
forum.xda-developers.com
Downloaded the -fastboot EU ROM which came with it's own .batch file in the archive. It pretty much wiped everything from the phone and installed a functioning version of A12/Miui13 and the handset is working again.
It's the same with me *anti 1*, I wanted to install miui eu. Is it smart, if anyone can give some advice. Thanks and regards .

Just like Mthw, i was on MIUI 13.0.10 EEA and anti 1, gone back and forward between stock (only used stock fastboot) and custom, only problem was trying to flash other roms from stock, without first flashing eu fastboot.
