How to downgrade from MIU 10 beta to MIU 9? - Xiaomi Mi 8 Questions & Answers

Some people say there is an anitrollback mechanism?
Is it the same with the Mi8?
What if I try MIU 10 beta I find it doesn't work well and I want to come back to MIU 9.
How do I need to proceed?

Flash 9.5 global rom via fastboot mode with mi flash tool

If your bootloader is locked, you will brick the phone if you try to downgrade. However, if your bootloader is unlocked, you can easily downgrade ( although I don't understand why one would downgrade since latest Xiaomi.eu MIUI 10 is more than stable ) .

Flash Global Developer via Recovery locked Bootloader

Hi everyone
First, I didn't find an answer form my question via search. Sorry if there is already one.
I'm now with an Global Mi 8 with Global ROM MIUI 9 9.6 (9.6.4.0 (OEAMIFD) and locked Bootloader. That's how my MI 8 got out of the box (so, the official Global version).
I want to flash the Gloabl Developer ROM 8.8.30 from the official MIUI Homepage (http://en.miui.com/download-346.html). As there is also a ZIP ROM Version for flashing via Recovery I want to ask wether it's safe to flash this. The verification process said no problems, just that all Data is erased. This is ok.
Is it safe to flash this way or is there a danger for a brick if the Bootloader is not unlocked?

It's safe to switch from global stable to global beta rom thru the updater, it won't brick your device.

Hello,
I was in your case with the same version.
No problem for me, I downloaded the version like you via the link then going through system update of the phone.
My bootloader is not unlocked
I'm currently on China Stable (miui9), bootloader isn't unlocked yet, what would happen if I flash globlal beta rom (miui10) (zip) via updater recovery?
It worked. Thanks

If your device is Chinese, you gonna brick it without unlocked bootloader.
So unlock it, flash then stay unlocked.
Is it possible to downgrade from 10 beta to stable 9 with recovery rom?
For the people who did. Did it erase everything on the phone? I am thinking of trying miui 10 but am too lazy to re-setup everything

Yes, it erases everything, back up all your data first, and save it on your computer
Hello,
I would like to flash Global Beta Rom on Global Stable rom thru adapter, but after touch 3 dots I do not have opportunity to choose the zip.
Do you have any suggestions how to do it?
Hello.
Click 10 times on the miui10 logo and submenu will appear.
Have fun
Thanks, it works :good:
Lol wrong thread

is it possible to downgrade from custom rom pie to oreo without brick..?

i'm using revolution rom 8.10.25 pie and now arb become 1...
is it safe to downgrade to another custom rom such as revolution 8.10.25 but oreo version. without brick..?
I would say so, but you're gonna need to format your data. So, in any case, make a backup, and then format..
I had been already on Xiaomi.eu Pie version, but since it was still a little bit buggy, decided to go back to Oreo Stable.
You have your bootloader unlocked, so as long as you keep it that way, ARB doesn't affect us..

That's NOT TRUE at all. ARB as Google intended would work that way, but Xiaomi implemented their own version of it. If you flash something with lower ARB index, you brick your device. More information here.

btw did u or have tried to flash firmware from oreo...?
Yes, I had. First thing I did when I got my hands on my Mi 8, was to unlock the bootloader. Luckily for me, I had an account already, from the times of my old Samsung Galaxy S3, which had a lot of firmware available, and I used Miui at some stage and created an account back then, which allowed me to unlock the BL straight ahead.
So after unlocking the bootloader, flashed xiaomi.eu , and root with Magisk.
FLashed a few updates of xiaomi.eu and when it came out, xiaomi.eu stable rom, based on china version( all of this rom's are based on china version)
But, I had already tried global, but because it doesn't allow us to install 3rd party themes, decided to go back to xiaomi.eu and keep it that way.
A few weeks ago, Android Pie, came out, flashed a beta version, noticed it was still buggy, and didn't saw much advantage on using it, not to mention the fact that it was draining my battery faster, so went back to Oreo.
What I did?
Format data, by going into Wipe in TWRP, and then press Format Data.
After that, flashed Xiaomi.eu Stable version of Oreo, and everything works great.
So yeah, it's possible to downgrade from Pie to Oreo, as long as you have a Unlocked Bootloader and keep it that way.

i think i know why still can be downgraded to oreo.... i look in fastboot (oreo stable v9.6.7.0) file "flash_all.bat" the "set CURRENT_ANTI_VER=1"..
and in pie also arb still 1... so which mean still safe to downgrade to oreo coz arb still 1....

It makes sense since it's developer version and people go from weekly to stable back and forth. With new stable and official release of Pie on MI 8 they would increase ARB index and it would not be possible to rollback anymore.

Where to find last Miui without Arb ?

Hello,
I got a new Mi 8, and didn't do any update to not get ARB (9.5.13.0)
As my bootloader is still lock for a couple of week, i would like to update MiUI to the last official stable version that don't have ARB.
Couldn't find any clues about :
- which is the last version (just found that anything after 9.5.17.0 should have it, but it seems for Redmi Note 5)
- where i can download it
Any idea ?

Just update through OTA for the lastest stable version. When you unlock your bootloader you could flash MIUI eu without ARB or any kind of ROMs you want to flash and enjoy it! That's how i do when i bought mi 8 one month ago. Update normally and dont be scared. Stable MIUI is still android 8.1 so no ARB confirmed. Without unlock bootloader you shouldnt flash anything except stock ROM.

i thought there is no ARB in stable ver until now ARB just prevent you to downgrade. If you like using global rom so nothing to consider. But if you want to go on other ROMs, you should stay where you are to be SAFE and wait to unlock bootloader and change to another one. I heard that if you dont want to be bricked when in ARB4 and downgrade to ARB 3, you just need to use MI Flash and flash stock China Rom (not global) in first then Flash the rom you want through TWRP. That's what i heard about :good:
Well, that's exactly why I'm looking for the last miui rom without ARB.
- to get update of the firmware (used by other rom)
- to switch rom without worry of brick
- to come back to miui if not satisfied at the moment by available rom

that's good to know, but i'm still cold feet about doing the update without solid evidence..
But i will look into it a bit more...
I Guess i will download the fastboot image and look into the script, i should get my response.
Thanks
afaik no mi 8 rom has arb higher than 1. you can check that in flash_all.bat. also, you should be safe from arb bricking if you always flash with miflash.

Indeed, just finish my download :
::set CURRENT_ANTI_VER=1
Well, i'm currently in 0 so technically, i will get arb

That's what i said just update the lastest through OTA ( i dont think there is arb on the STABLE ver) but for the safety he should stay where he is, wait to unlock bootloader and change to another one without any concerns. After unlocking, MIUI eu beta or stable is a compatible choice with arb 1 :fingers-crossed:
What is the difference between "standard" (ota) rom and fastboot rom ?
I mean, there is like 400mo difference... so it's not just the script.
Does standard rom have firmware, etc..?
Well, i did the update, and still no ANTI variable on my phone, so you were right !

What do u mean "standard " and "fastboot" roms bro?
There 2 kinds of roms: Stock and Cook Roms
- Stock ROM is the ROM developed by Xiaomi. Thats i call Stock china ROM. And maybe your global ROM is stock too
- Cook ROMs are the other ones developed by developers from many countries. These Roms have many other function which are very usefull depends on user's purposes and optimized better than Stock.
- About OTA, maybe - just maybe because i aint sure the other cook roms have this function or not- is only on Stock ROM.
- the only way to flash stock rom is fastboot. And normally, cook roms are flashed through TWRP. But your global ROM could be flashed by both ways.

well, it's what is called "local update" (basically OTA update) and "fastboot update" (flash) on Miui website.
Here an exemple :
Official rom from Xiaomi (https://en.miui.com/download-346.html) :
miui_MI8Global_V10.0.2.0.OEAMIFH_f1b5f34c66_8.1.zip --> Size: 1.6G
But from the same page, you go to "Flashing Guide", then "fastboot update" (http://en.miui.com/a-234.html)
" Xiaomi Mi 8 Latest Global Stable Version Fastboot File Download"
dipper_global_images_V10.0.2.0.OEAMIFH_20180912.0000.00_8.1_global_7d6e5e4b45.tgz --> Size: 2.4G
(Just to be sure, i uncompressed the tgz and did a zip -> 2.38G)
800M of difference, "same" rom.

Now i could sure that global is stock rom but with 2 versions- 1 for fastboot and 1 for recovery. Fastboot ver has some system functions which will help you unbricke some softbricks like cannt flash other ROMs and stuck in fastboot, bootloop etc... Recovery could also helps you but sometimes you have to use fastboot when it cannt. When you want to update or go on other ROMs, use recovery or OTA is more faster than use fastboot. But when you dont sure about ARB and want to be safe, thats when you should use fastboot to downgrade because recovery like TWRP dont check ARB. Only downgrade, update to newer is ok. And fastboot has .tgz tag, recovery has .zip tag.

Question Can stock zips be flashed with mi 11 twrp?

Just wondering if the stock zips can be flashed with twrp?
I tried numerous stock zips and the ROM flashes successfully with no errors, xiaomiflashtool V2 is also successful, however when the phone boots no matter which stock ROM succeeds, Xiaomi.eu is the ROM that boots.
I don't want to use mi-flash, my phone is eea(Vodafone) and I'm trying to flash eea global, when switching with mi flash it activates ARB and bricks the phone. I know it does because I have already done so and got a replacement from Vodafone.
Any help to flash a stock ROM would be appreciated, I'm stuck with xiaomi.eu as it stands.
Cheers.
at moment . there still no recovery rom for Xiaomi Mi 11 . there's people trying to flash stock rom in TWRP but keep failed .

Mine doesn't fail though, it succeeds. Well shows it succeeds but boots to xiaomi.eu each time.
Xiaomiflashtool V2 also succeeds with the stock ROM , but same outcome is present, xiaomi.eu boots each time.

I dont really want any custom roms really, ideally looking to flash stock again but its proving difficult.
hello me i think wait for a stable recovery.
At the moment the "TWRP" that is out is A10 based therefore you can only do normal stuff like wipe, flash magisk etc. It does not support flashing A11 roms yet

Hi you can, but you need the bl unlocked, also with china phones you might need root for gpay, banking fp etc.... with the bootloader unlocked these things may or not work, however on Chinese phones the bl must remain always open on a custom rom, otherwise the phone will brick.

Should i flash official miui to completly reset my phone ?

Hi guys,
i flashed tons of roms since i got my phone. Now i want to revert back to miui 10 android 9 ~v10.3.17 - xiaomi.eu, as miui 10 always was best with battery life for me.
Should i first flash the official stock rom from c.mi.com with fastboot mi flash tool to get rid of all my mess i have done in those years or can i just flash xiaomi.eu via twrp ?
I have the chinese version redmi k20 pro 8gb 128gb raphael.
Thanks.

Flashing Xiaomi.eu will only replace the system. It's probably better that you first re-flash the complete stock, also MIUI 10/A 9, to have the clean situation like in the old days
@zgfg thank you very much for your answer.
May you can tell me if i should prepare anything to get the bootloader unlocked again easily or is it the same procedure like requesting the file from mi.com ?
And maybe you can tell me if i can flash eea or global rom aswell as i live in Italy/europe or china is required ?

I suppose your BL is unlocked since you were flashing.
You can check in Fastboot:
fastboot oem device-info
Regarding how to flash the fastboot firmwares, see (I didn't use myself):
How to Flash Xiaomi Firmware using MIUI Fastboot and Recovery ROM
Ever since the dawn of affordable smartphones in countries like India and China, the demand for more has increased. The consumers now, more than ever, are
www.getdroidtips.com
Long ago, when I switched from stock to Xiaomi.eu, I switched from EEA (but AFAIK, Xiaomi.eu guides nowhere require to be coming specifically from EEA, Global, China, Russia)
Yeah im unlocked, but if i recognize it correctly flashing stock will lock bootloader again.
Need to do further research tomorrow than if i can prevent that somehow .

Take a look to the screenshot from Mi Flash in the guide, there is the option Clean all vs Clean all and lock
That is a common issue, people leave on default: Clean all and lock and if anything goes wrong while flashing (wrong firmware or something) they hard brick their phones and since they locked them, they cannot flash again (and must ask for the paid EDL support)

Thank you so much for pointing that out, i surely have missed that.
If i can keep it unlocked may i stay at stock and will do a lot of debloating and optimization as i wont update it .
