There's no anti-rollback on MIX2.

Is that still the case? I have a mix 2 with MIUI Global 10.0 stable 10.0.2 .0. Does it still not have anti rollback protection? Would I be safe to unlock the bootloader and install any custom ROM?

There's info on it in this thread of mine, and you can always unlock and flash custom ROMs. Just make sure that when you go back to MIUI that you flash MIUI via fastboot or MiFlash and not TWRP. Also use MiFlash to switch between MIUI beta and stable and when downgrading MIUI. But there is no problem with custom ROMs.

Thank you so much for the response. Your thread looks like it is jam-packed with some really useful information. I'm certainly going to read through it. In any case, in a nutshell does this mean that my phone currently does not have the anti roll back protection on it?

It has, but you can unlock and install custom ROMs. But if you go back to official MIUI, flash it via MiFlash or fastboot.

which rom is the best for OTA?

my Mi5s arrived yesterday, system says i'm running MIUI 8.0 Global 8.0 Stable 8.0.3.0 (MAGMIDI) rom,
Is this the best rom for OTA?
Is this the latest official rom avaiable?
are there any better rom options based on MIUI which receives ota updates?
thank you in advance
Matteo
Official global rom's dont updating....now the latest version is China stable 8.2.5.0....but global stable is stayed in 8.0.3.0.....xiaomis not updating GLOBAL OFFICIAL ROM FOR MI5S....but now coming Global developer rom 7.5.18....it is good for ota....but if you dont want dev Rom...you can Root your mi5s and flash Xiaomi.eu rom....its unofficial Global Miui....and very good and stable for use....Xiaomi.eu is based on China Stable latest version but without Chinese content and with more Supported languages....
Except that Xiaomi.eu stopped their OTA support.

except as you're on 8.0.3 you're s**t out of luck - you can't update, you can't root because you can't unlock - unless you use a deep flash cable and MiFlash a different Miui ROM with OEM unlock status available.
then you can unlock, and flash any ROM

On the first attempt error occurred in 50%, so I uninstalled the driver and installed again, That's it!
Edit: I used the software from Xiaomi.
I'm using official global 8.2.1.0, is it possible to install the global dev 7.5.18 without error ?
I mean, I tried to do it using TWRP but, again, it got stuck during installation. I know it's possible with a fastboot version, but we don't have it.

Can I install MIUI 8.7.26 (MIUI10) without worrying about ARB?

I have a Redmi Note 5 Global with MIUI 9.5.19, and I want to install 8.7.26 (MIUI10) because I can't unlock my bootloader yet (14 days to go).
My question is: can I do that safely without bricking my device? And can I go back to MIUI 9.5.19 if I wanted to?
Thanks!
I did same thing and it worked flawlessly.

You have a locked bootloader? You used a recovery ROM or a fastboot ROM (MiFlash tool)?

Just update through the phones settings with the zip file. You might need to try different MIUI 10 versions. There is always only one version you can go to from your current MIUI 9 version. Took me 4 tries but now it's working great

I flashed MIUI 8.7.26 through the method you mentioned without issues, but it has so many bugs, especially with notifications on lockscreen that bother me so much. Do you know if I can revert back to global stable MIUI 9 with the same method without issues with ARB?

Am I safe to proceed?

I'll be able to unlock my bootloader in less than 24h, and the first ROM I want to try is the Pixel Experience ROM (android P). I'm currently on MIUI 10 8.8.23 Global version. Can I just unlock the bootloader, flash RedWolf Recovery through adb, do a full wipe and flash Pixel ROM without worrying about ARB or anything?
Thanks!

Umm dude read my post again. I said I'm on MIUI 10 8.8.23 (which is the latest one), I don't want to flash MIUI, but I want to flash Pixel Experience ROM. How will that trigger ARB? I understand very well that if I want to go back to MIUI, I need to flash the latest version of MIUI available.

Just flash pixel ROM
For other custom ROMs do not flash any firmware file recommended by custom ROM developer, because those firmware files are 8.7.5 MIUI firmware. If you try to flash firmware files then you are going to brick your device

Not yet, still 2 hours to go.
I'm on the latest MIUI 10.0.0.1 stable Chinese.
I just want to flash the latest Global. Can I do this by just unlocking bootloader, flash RedWolf Recovery, then flash the latest Global recovery.zip file? Or do I need to worry about ARB?
If you want to go back, make sure you will flash these version or higher

Q about rollback

—Answered— Thank You!!
Hi, I just bought Redmi Note 5 today and after I turn it on, it is already on MIUI 10 8.7.5 Global Beta. The question is, can I roll it back to to MIUI 9.6 Global Stable? Because I found this rom isn't comfortable and I found so many bugs. I don't want to update it to MIUI 10 stable yet because ppl in MIUI forums complained that there are some bugs.
Thanks
Wtf...New device came with Developer beta rom?

8.7.5 miui 10 is ARB3 you can rollback to 9.5 miui 9.5.17.0 thats last ARB3..
or get 9.6.4.0 thats ARB4.
How come new device comes with beta ROM?? Something wrong with reseller please contact ask them
Right now your device is on arb3 (no antirollback) you can upgrade to latest version with firmware less ROM

Yeah I know that... What I mean to say is. Most of the people download official ROM package from official website and try to flash update using custom recovery and this will cause mobile brick..
That's why Xiaomi suggest not to downgrade to Oreo after android pie update (miui android pie)

No it's a problem, even if you flashed firmware-less most of the functions won't work, at least that's what happened with me, no camera, no earpiece, no vibration and ofc more under the hood.
We're stuck on pie and even the custom ROMs need to be updated to the new vendor because the situation is the same.
Pie is so far so good but I'm surprised that exFAT isn't working!! now my sdcard is useless! i checked and the module is missing which is exfat.ko, don't know if they forgot to add it or what now!! also all the recoveries i tried give a problem with data and encryption so it need to be updated, other than that all is good.
Anyone tried latest xiaomi.eu build 9.3.25?

TBH I didn't try because of the problems I heard people were having. But with the original pie update I had to use orange fox recovery just to get out of encryption it was a mess. I am going to try to flash a pie rom but if you are flashing an Oreo MIUI make sure the firmware folder is not in the zip or you will brick your device.

Agreed. This seems a bit strange for me. Are you sure guys you cant simply go back to Oreo?
As long as anti is fine, it should not be a problem. Maybe there is a new mechanism now which we dont know.

I've Installed China and Global Pie then reflashed 10.2.2 without problems with MiFlash, haven't tried with custom recovery, i think you will not have problems.
Guess I will hold off MIUI Pie until its finalized.

Yes you can do anything if the anti version is same..
But Xiaomi recommends not to downgrade to Oreo after android pie update. (There won't be any problem as long as we use MiFlash tool)
Maybe Xiaomi will introduce new anti version for stable android pie update
Here http://en.miui.com/thread-6004916-1-1.html you can read moderator suggests not to flash Oreo ROM after updating to android pie.
Maybe Xiaomi moderator mentions same thing for our device during public beta release
For those stuck on the new miui pie, a possible solution:
