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.

Yes, you absolutely can. Even in ARP3 you wouldn't have any problem. Only ARP4 is a headache for us. So be careful not to upgrade your bootloader to ARP4.

Just flash miui rom (.zip) from TWRP or u can use miflash (.tgz). Even with level 4 you can return (only to 9.5.19)

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)?
Thanks!

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?

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

You can directly go from MIUI10 to 9.5.19
After downgrading just do a factory reset

I am on Pixel Experience rom, and want to try another rom, Help me

I am on Pixel Experience rom, and want to try another rom. I was on MIUI 10.02 and I unlocked bootloader and installed PE rom. Now I want to try another rom, but am afraid of bricking phone. Is it safe to flash another custom rom? or what?

Flashing Custom ROMs is safe leaving aside MIUI based custom ROMs.
Go from Oreo to Pie or Pie to Oreo without a doubt in any AOSP or Lineage OS based ROM, but if you ever want to go back to MIUI or any MIUI based ROM just ensure that you install the latest version or the version higher than the one you had previously.
Only the firmware found in MIUI ROM is responsible for bricking. So you can also try firmware-less MIUI ROMs. There are many relevant threads regarding it.
Just do a search.

Ok what are roms that based on miui to avoid them?

It's easy to find by the nomenclature.
Their names include MIUI or a variation of it.
Some are: Revolution OS, MIUI Pro, MIUI Eu, Masik ROM.

Did u mean that miui based rom can brick my phone ?
Did u sure for that ?
I think the only way to brick it to go from arb4 to arb3 in miui official rom only but the miui based roms i dont think so .... But if u sure about that tell me again ?

I mentioned that you should always install a MIUI build that is of higher version than you previously had to be on the safer side.
After MIUI 9.5.17, ARB protection bumped to ARB4 from ARB3.
So, once you update to any ARB4 version and then make a mistake of installing any MIUI build of ARB3, your device will be bricked.
That's why I mentioned that always ensure that you install the latest build or the build with version higher than the one you had previously installed.

I believe his question was about custom MIUI roms which have firmware update removed so that risk of bricking is non existent. I believe reading that Masik does not contain firmware, but I'm not sure.
Other than your good explanation about ARB4 vs ARB3, one thing to add: anyone on ARB4 can flash any ARB4 rom since the bootloader checks for anti rollback protection index but not the MIUI version specifically. So any rom starting from Stable v9.5.19 if I remember and Beta 8.7.6 are safe, until ARB5 comes (if it comes, and if it requires ARB5).

as long as they tell you in the rom features or installation that doesnt affect ARB or doesnt touch firmware its ok.. but not sure if not all miui based roms have firmeareless. so you need to read rom intructions.

PE Extended. Also depends on the Kernel. But nothing like MIUI gives you better battery life.

try mcaosp rom... you won't switch to any other rom ever... best custom pie rom in my opinion. or if wanna go for miui based go for masik x1.7
