Is your bootloader unlocked and have you got twrp?

Even if his bootloader is locked Poco doesn't have any lock on it that control what version of software to have your best bet is Google it's your friend don't be lazy......

If bootloader is unlocked then older miui can be flashed using twrp. Then a facotry reset is required to get to homescren. I've done it myself, with global rom, downgraded from 11.0.4.0 to 10.0.3.8 (however now back to 11.0.4.0 again)
*Factory reset will delete internal storage too so backup everything before downgrade.

Thanks for the reply,
I found a topic for Poco F1, here on Xda, with some info about unlocking bootloader and installing TWRP and I managed to unlock the bootloader after many attempts.
So I unlocked the bootloader, but did NOT rooted the phone. Transfered TWRP with ADB minimal commands, but when I restart phone in recovery TWRP asks for password for decryption. It lets me cancel the screen with password, but when I try to wipe cache and data gives error for not having permission. So I abandoned this method.
I google it and found another way to install roms, thru MiFlash, the tool from Xiaomi website.
The question is: Can I flash Android 9 MIUI 11 Global stable version with MiFlash with succes?
I have now installed on my phone Android 10 MIUI 11 Global stable version...

I've never used miflash so can't answer, sorry.
going back, i belive you had to flash disable force encryption.zip in twrp. This could remove the encryption.

I fiund different videos online but none for the poco f1 regarding the downgrade with stock rom with MiFlash. It said that it would work with all Xiaomi models, but I don't want to make something stupid, that's why I am asking in this community, maybe someone knows more info about it.
So what version of TWRP you use? Where I can find a working version of the ,,disable force encription.zip" for poco f1?

as far as I know MiFlash is one of the safest ways to flash stock miui for afresh new beginning.
I always use this when I run into any problem. (but u shud get as many experts opinions as possible)
Now coming to the point of "downgrading", I m gonna downgrade my device to check whether it bricks or not.

Once you've done that, format system and data. Then get twrp flashable miui 10 from here:
https://mi-globe.com/miui-firmware-rom-builder-features/78/
After flash, you need to format data to be able to get to homescreen. It works for me and i downgraded more than once from miui 11 (android 10) to miui 10

Thank you for the help, I wil try to do that and come with feedback. I supose i can install TWRP using minimal ADB commands like I did before, then try to flash the zip with the decryption data.
But you say you downgraded from miui 11 (android 10) to miui 10...is still viable for me to downgrade with this method from stock global version miui 11 (andoird 10) to stock miui 11 (android 9)??. I only have the bootloader unlocked, NOT rooted

While flashing I selected clean all+lock bootloader. After successful flashing and booting, I used "unlock tool" with MI login on the device+on the unlock tool and it didnt give me trouble (waiting period to unlock etc) to unlock again. So its pretty simple if u knw wht u r doing.
Happy flashing

You'll need fastboot commands to flash twrp.
Yes, I've downgraded from global to global. If using twrp, you need the rom in flashable zip format.
Can't see why bootloader can't be re-unlocked.

Yes, I've seen that roms for Twrp are in .zip format and the ones for XiaoMiFlash are .tgz format.

Yes, I will do that, check everything twice and don't rush. Everything should be properly done, step by step.
I still have a question.. if I have my microSd card in the phone while I flash a rom or wipe data it will affect it? I will loose the data on it? Should I get it out while doing the procedure?

Although I feel that it shudnt format sd card, I would simply remove sd card when wiping and insert it back when needed.:good:
I dnt wanna take chances.
Its upto u nw.:fingers-crossed:

Unfortunately it is as you can see from the file name.

see the patch note for more
It's prettier, few new options and better battery life than MIUI 7. My first impressions
I flash this rom in my redmi note 3 pro and I install gapps and rooted the phone with supersu, putting the gapps and supersu Zips in the microsd and follow the method to entry in twrp to install the Zips without lose the original recovery (the system of the forum given't permissions to me to put external links) .

Well, you flashed the ROM which is not for your phone. It's redmi 3 forum, not redmi note 3
Hi, I flashed the correct rom for my device, but the method is valid for all devices with miui 5-8, with official unlocked bootloader, and original recovery, sorry for the confusion xD.

What process did you go through? I'm interested in MIUI8/root/GAPPS.
As for MIUI8 it seems that the only available version is the China Dev one. It comes bundled with a ton of useless chinese apps, no root, no gapps.

Mine hv previous china dev rom installed (miui7 6.5.26) before, and i was download miui8 from official site and flash it manually via updater (choose update package). No data loss or relocked BL after (even all my games still there)
Gapps using google apps installer.apk frm mi market.
Root: just tap root permission in security apk and it will download (i assume its miui root file or something) and device will rebooting by it self after. Done.
Ps: i have no superSU installed.

Thanks for the answer. What I did, is flash it from the TWRP. I must have missed that I can go from 7 to 8 from within the OS. Now I'm back to 6.5.2.6 so it's good to know. I'll update soon.

This guide explains how to flash stock MIUI roms. You have a few options for root. You could flash a global or China beta/dev ROM which have an in built root which can be enabled. You could unlock your bootloader and install TWRP then install superSU. Or you could just try an app like KingRoot if you trust it enough.

I've done it with the China dev/beta rom and that is what's recommended. It may be possible on the new global dev but I'm not sure and so can only recommend the China dev/beta. Once unlocked you'll stay unlocked so you can flash whatever you want straight away after. Just make sure to backup/sync any data first as everything will get wiped when using the SP flash tool.

It was a simple and normal question. I don't bully you or anyone else here. It's better if i ask you before you brick your phone or something. But anyway, it's your phone and your choice.
Global dev rom works, I unlocked mine early this week. You will need to fill in the form for permission from Xiaomi hxxp://en.miui.com/unlock and wait for an activation code for your Mi account before you start. You'll also need that account on your phone. It absolutely will not work on Global Stable, trust me, I tried!
The Global Dev rom doesn't have root enabled, so you'll also have to install TWRP (from cofface) there is a good guide in this forum somewhere, then flash SuperSu from there. (the official version works just fine)

Thanks for confirming, I unlocked using the china dev rom and enabled the built-in root. I could then use flashfire to install cofface's TWRP recovery and did a wipe in TWRP to start afresh without root.

Bootloader can even be unlocked on Global stable now. Just did it successfully on 8.1.2.0. Next TWRP can be flashed via fastboot and last SuperSU in TWRP. All done.

No reason why it should not work on 8.1.3.0. Just look for the bootloader check in developer settings. If it's there and you can link your account you should be good to go. Always worth a try...
Latest Supersu is always available on Chainfire's website download.chainfire.eu. Flash via TWRP. It's not specific to A ROM or device.

[Q] Flashing Pixel ROM Redmi note 3

I am very keen to know about flashing ROMs
I am using Redmi note 3 SD 3G. I want to flash the pixel ROM for my device and I have the following doubts
1) Do I need to unlock my bootloader or without unlocking my bootloader I can directly flash TWRP?
2) If yes, then do I need a beta version of MIUI for unlocking my bootloader cause I have been trying since a very long time but it is stuck at 50%(I tried all the solutions).
Thanks a lot in advance
1. U have to unlock ur bootloader for flashing custom recovery .
2. it should be unlocked on any version but dev versions have more chance of unlocking than stable ones (especially china rom,s have high probability )
3 U can try unofficial bootloader unlocking but do it on ur own risk as it can hard brick ur device .

Wait for a few days or couple of weeks, that helped in my case. Update and try syncing your Mi account on your phone.
Follow the instructions here
http://en.miui.com/unlock/
If nothing works, follow this guide, just flash any ROM of your choice with TWRP.
https://forum.xda-developers.com/redmi-note-3/how-to/kate-guide-install-lineage-os-locked-t3546154
And if you want the Pixel experience, install PureNexus ROM, it is better.
Just flash lineageos with stock gapps. And then flash my universal pixelmod. It will give you full pixel experience. Nav bar not included yet. Will include it in future.

How to install developer rom ?

Hi guys, I heard that it is easier to get bootloader unlocked on developer rom so i am trying to get it.
I downloaded it from miui website , the developer ROM for RN4 Qualcomm global. Then when I put it in sd card and try to install it via updater app, it first does all that decrypting thing and shows can't verify file. WHat do I do ? How did you guys get to install develoepr rom ?

I downloaded it from miui website , the developer ROM for RN4 Qualcomm global. Then when I put it in sd card and try to install it via updater app, it first does all that decrypting thing and shows can't verify file. WHat do I do ? How did you guys get to install develoepr rom ?

What you heard is wrong.. the only way to unlock bootloader is patience.. wait 5-10 days after getting the sms and try unlocking every day.. you will get the unlock eventually... I tried every solution on the internet and I can guarantee you none of them work..
As for the dev rom install.. you simply can't.. the updater will say can't verify package.. English Mi PC Suite won't detect your phone on recovery.. China PC Suite will detect it but it will say you can't flash developer ROM over stable ROM.. and fastboot flash will say can't modify partitions (requires unlocked bootloader xD).. believe me I have tried them all..
PS - i'm currently on lineage and going to flash AICP today

Sorry but no, pm me here if you want
If your mido at 8.1.10.0 or 8.1.15.0, you can only flash with updater to 7.2.16 glodev.,because it is still MM.
Can't verify, because it's N ROM, different version..

You must flash the persist partition with twrp. You can find a tutorial at the 4pda site
I am having the same problem.. any solution??
Thanks in Advanced..
I read on a latin facebook page, that you need to install some rom, the majority agrees with miui 11 to start it, to activate the usb depuration and to install the global and european stock android one 9.0 rom and that the problem is corrected, i do not correct why the process has to be that.

No i did not.
Developer option bootloader unlocked and usb debugging activated
Fastboot unlocked using adb fastbioot
And flashed the official fastboot rom using mi flash tool

Can you go back to 10? They say just make a backup of persist partition via twrp then flash it

Flash any custom rom (PE in my case), then flash stock rom again....

So basically, i updated to stock android 10, realised it was a mistake, flashed stock 9 via fastboot, lost sensors, installed orangefox rexovery and flashed latest PE, while in PE i tested the sensors and they were fully working, flashed stock 9 via fastboot again and everything is fine now. That was it.
Every time The same story. Before the update every user want it like a question of life or death. After ask how to downgrade. LoL

Strange, i've used the method twice now with success. Are you using the official march fastboot rom from xiaomi and the latest platform tools?

You guys are missing an important step; for the downgrade to be successfully done, you must come from a custom Android 10 ROM for Pie vendor, as such only the official PX is eligible, not the unofficial by nullby, because the latter uses Stock 10 firmware, vendor included.
I suspect it's because dtbo.img, since it carries hardware information to the Linux Kernel, thus the sensors would be targeted.
You can use any custom ROM that matches the requirements, as such the EvolutionX by chaplindev; but I do recommend to use PX Official build, just because that's what I used to recover my sensors back; download is available here.

That's the one i used both times and successfully restored the sensors..
Solved
Just Download laurel_sprout_global_images_V10.3.4.0 This Rom and Flash .....I think everything will work fine.
When i tried others like v10.3.16.0... Also facing same issue.
