Nooo never. You are privileged to have anti3. You want to keep it. You can flash fwless miui ROMs which you can find here https://xdaforums.com/redmi-note-5-pro/how-to/index-redmi-note-5-pro-miui-roms-t3816343. But never flash a rom that has anti 4.

Hi All...

20 days ago I bought my phone and once I bought it I applied for unlocking permission and I got the permission but still didn't unlock, I'm planning to unlock and flash custom treble Android P , my scenario is once I find a fully stable custom Android 9 I will unlock and flash... In case I wanna go back to the fully stock phone (locked with the latest MIUI installed) Can I go as the following...

1- Wipe everything using TWRP

2- Flash LATEST stock fastboot rom of MIUI -preventing ARB blah- using XiaoMiFlash.exe with the option clean all and lock.

please advise if this safe or not...
[Xiaomi Redmi Note 5 Pro Guides, News, & Discussion] MeDoOoS:
You meant that ,, I can install any AOSP ,, but when I back to miui ,, should flash last version or version that newer than last miui that I flashed before flash AOSP ?
[Xiaomi Redmi Note 5 Pro Guides, News, & Discussion] taco9:
From first page:

It depends on which version of MIUI. Some older versions dont have ARB, but if you flash new ones (9.5.19 and above or miui 10 betas), you will get ARB4, in which case you will be stuck with ARB4 and must be careful not to go back to earlier versions unless you flash MIUI without firmware (no bootloader) as mentioned above. I am a new RN5 owner with 9.5.19, so not experienced with older versions, some of which have ARB3, pls confirm with others.

I think is possible, because I read that both versions use ARB4. But wait for more opinions.

1: When I will to install the custom ROM, what should to wipe? ( I usually wipe all except Micro SD, it's that ok?) (Have any risk?)

2: Return to MIUI it's safe?, probably in the future when i will change my phone will try the MiFlash using the option "Clear all and lock" and install the newest stable ROM, should be this a problem with the ARB 4 ?

3: Can I install TWRP after install a custom ROM or this could brick my device (i'm very afraid of the ARB 4 ), or it's better lauch TWRP from the ADB comands always?

4: And the kast question: It's safe to install Magisk on MIUI? (Probably I will get only customs ROM, but i want to know that).
[Xiaomi Redmi Note 5 Pro Guides, News, & Discussion] dlghowk:
1. Normally the OP leaves the instructions to do anything, like the wipes, flash instructions, etc. But is very common to wipe only system, data, cache. Just follow the instructions.

2. Antirollback is going to react only if you are trying to flash older firmware. If you're anti 4 you can do: flash any anti 4 rom (or modified anti 3 roms without firmware) and upgrade to future anti 5 roms (Which would make your device anti 5 too)

3. Once you install TWRP you should boot it from the adb commands... Or just before it goes to MIUI try to open the recovery menu by pressing volume-up + power (It could be different). if you are going to keep MIUI you need to flash lazyflasher to keep TWRP permanently... or just install another rom while you are in TWRP.

TWRP or any other custom recovery doesn't include any kind of firmware update.

4. Well, being honest I don't know. I think is going to be fine but who knows.

You can flash farmware less miui ROMs which you can find here https://forum.xda-developers.c...note-5-pro-miui-roms-t3816343.

For check ARB version you have to type the command 'fastboot getvar anti'. Then you will be sure on how you should proceed.

Yes you can flash it. But you have to use fastboot method to change China ROM to Global ROM

Download 9.6.3 fastboot ROM and flash it using MiFladh Tool

Just follow this en.miui.com/a-234.html
[Xiaomi Redmi Note 5 Pro Guides, News, & Discussion] dlghowk:
If it is 9.5.19.0 or higher, everything is going to work just fine.

Before, check what version of anti you have with:

fastboot getvar anti

(You don't need an unlocked bootloader to check that)

If you're anti 4 and want to come back to older versions of MIUI, please go here:

I have a redmi note 5 global 4/64 with pixel experience Oreo and I wanted to go back in stable miui. My last firmware was miui 9.5.19 global stable (ARB 4) but now there's 9.6.3. Can I install 9.5.19 instead of the lastest one? ( I have downloaded it from updater before switching into PE) Then how ota with redwolf recovery work?

I got a question, if anyone with more knowledge about this arb stuff wanna answer.

From what i've gathered, there's no difference between arb3 and arb4, except the fact you can't flash an older arb3 firmware if you're on arb4.

Now, i've upgraded from vince and with that device, firmware had a big role in battery life, newer global firmwares were underperforming, while older firmwares, one in particular had a great battery life, especially in deep sleep (i know that probably you think that's BS, but trust me, i've had that for like 5 months now and there is a big difference in battery life inbetween firmwares).

Now what i wanna ask. Is the same thing here? Is battery life or even perfomance (kernel wise) affected by which firmware i'm on?

I'm currently in 9.5.13.0 which means i'm on arb3. Since i won't be using miui, only aosp custom roms, i really don't care if i'm on arb4 or arb3 or whatever.

The only thing i wanna know if there any differences battery and performance wise just in the firmwares alone.
[Xiaomi Redmi Note 5 Pro Guides, News, & Discussion] SunilSuni:
Vince has SD625 that's why it is power efficient

But whyred has SD636 so power consumption is little bit more as compared to SD625

With 9.5.19 you will get better battery life 9.6.3 also good update you can choose any one. For more info checkout SOT thread

[Xiaomi Redmi Note 5 Pro Guides, News, & Discussion] siddesu:
Got a new whyred phone, with 9.6.4.0 global. After a needlessly long wait, unlocked the bootloader today. Tried to flash TWRP and failed miserably.

What I tried so far:

1. TWRP flashing method.

1.1. Reboot to fastboot, plug the phone

flex15 # fastboot devices
13c9c406	fastboot

1.2.

flex15 # ls -l twrp-3.2.3-0-whyred.img
-rw-r--r-- 1 x x 37195776 Sep 2 19:56 twrp-3.2.3-0-whyred.img

1.3.

flex15 # fastboot boot ./twrp-3.2.3-0-whyred.img
Downloading 'boot.img'

The result is, the upload hangs until forever, TWRP doesn't boot, doesn't work.

2. Try to flash older stable roms. Didn't work, which is, of course, expected, as this is an older ROM than the one I have and I hit the protection.

flex15 # sh flash_all.sh
product: whyred
Sending 'xbl' (2506 KB) FAILED (remote: unknown command)
Finished. Total time: 0.001s
Sending 'xblbak' (2506 KB)

Hangs here, does nothing.

III. Custom roms - didn't even bother.

IV, V. Tried flashing the dummy.img, it also hangs without completing the update.

fastboot flash antirbpass dummy.img
Sending 'antirbpass' (8 KB)

anti var is 4:

flex15 # fastboot getvar anti
anti: 4
Finished. Total time: 0.001s

So, two questions.

1. Have I missed something stupid along the way which is the reason for the failure? Any hints appreciated.

2. What now? Any tests or different steps to try?

Thanks in advance, and #%@$ xiaomi and google for sticking it to the customers.

And make sure it is in the same directory on PC, that you have run CMD/Powershell from.
