You receive OTA updates no matter if you have TWRP or not.
But for the automatic OTA to execute, you need stock Recovery (you can always flash to switch from stock recovery to TWRP and vice versa)
Alternatively, you can download OTA zip and install theough TWRP
There are really many threads about (it's not specific for this or that Xiaomi phone) and generally info on Internet.
Please take your time, search, read, do your homework, get informed

Sorry, I'm not using/did not need Mi Flash and besides, I remember that when I was interested in and I was looking for, I found many and good guides here on XDA, on Internet and YT
Hence again, if you are interested in something, take your time, search, read, Google is your friend - as all of us do when we need something new
If too complicated to search and learn, better stay on stock bcs sooner or later (if you didn't do the homework and learnt it good by reading varios guides yourself) you will make a mistake, get a brick and start asking for help. And it's always hard to help to newbies who just jumped into something, without studying and well understanding things themselves (they don't know to describe the problem, what they did to come to brick, they don't nunderstand instructions experienced users give them, it becomes a waste of time)
Sorry, but that's the way it goes

If you ever messed with Persist (flashed over, wiped), you lost Widevine L1 and forever. Unfortunately, some AOSP custom ROMs also overwrite Persist and you loose L1

Simple guide for unofficial BL unlock, TWRP, root - Redmi Note 3 Pro Kenzo SD

This guide is meant for people that have experience in flashing Android phones. I just consolidated the information from various threads around the web, so it's easier to find.
Advice here works on the latest Lollipop MIUI stable ROM, 8.0.5.0 LHOMIDG for Kenzo Snapdragon version. I tested it myself.
Just to be clear, I am not responsible for any possible problems you may encounter white attempting to do anything mentioned in this post.
1. follow this guide to unlock the Bootloader unofficially ( http://en.miui.com/thread-253680-1-1.html )
2. do not use "emmc_appsboot.mbn" from the above thread, or you will have a bug that causes your notification led light to blink red constantly, while the phone is connected with a USB cable to a charger, or a PC.
3. use "emmc_appsboot.mbn" from this thread ( http://en.miui.com/thread-280771-1-1.html ), or if you prefer, this is the direct link ( https://drive.google.com/open?id=0B6qi9i0uOR-BY21NRGxVN1JiRDQ )
4. install recovery from this thread ( http://forum.xda-developers.com/redmi-note-3/how-to/zcx-twrp-install-twrp-flash-supersu-t3462448 )
That is all. Enjoy.
EDIT: Apps that are safe to freeze with Titanium backup are listed in the attached screenshots. Remember, do not uninstall or remove them. Just freeze them. List updated on 10. Nov 2016
Also, my advice is not to bother with official BL unlock. It's just a data mining operation by Xiaomi. They use it to get your e-mail account, phone number, location and who knows what else... Also, avoid any MI related services, like MI accounts, storages, backups and sync.
After rooting the phone, FREEZE but do not REMOVE any bloat apps. Do not forget to firewall MI apps!
ty for this, although I agree with you they use this for data mining, but unlocked it officialy anyway, because they gave me permission in few hours... Also unlocking only takes like 5sec,
I use dropbox & google stuff so they have my data already
Agreed, but there is no need to add Chinese to the mix
I will post a list of apps that are safe to freeze in a few days, as soon as I finish testing.
List of apps ( screenshots ) added in the first post.
Updated the list of frozen apps. This is as good as it gets, without getting force close on anything.
Thank you. Your thread helped me with the red light issue.
mhm,this method work in miui 8 global 6.12.1 beta? ( dev)
tested and success. thanks you
tested and success. thanks you
@Tomo123
Please confirm, that Using this ROM as base would work for unlocking unofficially?
http://bigota.d.miui.com/V8.0.5.0.LHOMIDG/miui_HMNote3ProGlobal_V8.0.5.0.LHOMIDG_a831ea486e_5.1.zip
And, i plan to use AOSP roms,but please tell me how to go back to STOCK MIUI ROM[without brick] in future if i decide to unlock officially, i have already got the permission, but the unlock tool stuck at 50%.. cant wait more...
Thanks for the help.
Confirmed working.
I'm on MIUI Global 8.2 (8.2.9.99 LHOMIDG) will this procedure work? I just got my Redmi Note 3 Snapdragon variant today and i want to Root it, Xposed it and Enjoy it

Thanks for the reply, i could unlock the bootloader successfully, but i have a problem.
when i rebooted to the MIUI system ROM while in the process to unlock(after unlocking the bootloader),
i could observe that there was no network, my 4G sim couldnt be detected.. And thereafter when i try CM14.1 or RR rom, i get network but cant make calls/sms but 4G data works.
I tried a few Nougat firmwares, but same problem of no calls/sms
I am getting the feeling it all started from the 5.1 MIUI ROM with no network..
So i was thinking to flash the latest global/dev Marshmallow ROM and start over the BL unlock process.. will it help? have any ideas?
And the most important Ques is that the bootloader talked here would even work on With marshmallow ROM for unofficial unlock or not?
Please suggest.
Thanks.
I've tried this guide loads of times now and I'm always stuck with "FAILED (remote: oem unlock is not allowed".
All the info regarding the problem mention to boot into the system and turn on oem unlock in the developer options. But I can't boot with the modified emmc_appsboot.mbn I only get the Mi logo flashing.
Any ideas?

Recovery bricked after Nougat update?

First excuse me for opening an other thread like this, i think i have read all other threats regarding my problem, but none have the same situation
My Huawei M3 Wifi (BTV-W09) seems semi bricked after installation of Nougat Update.
The Installation (Force Install with dload) gave me an error and also while boot i got the error message: "Your device has failed verification and may not work properly."
I have the option to press "Powerbutton" and the device will boot up. I checked the Version and it showed android 7 + EMUI 5. The only problem was that almost every system app was missing, like keyboard, calendar etc. (playstore was there)
So i tried to do the rollback with:
HUAWEI MediaPad M3 8 Rollback Package%28BTV-W09 %2CC900B300%2C EMUI5.0%2BAndroid7.0 rollback to EMUI4.1%2BAndroid 6.0%29
The Installtion (force update) gets stuck at 5% and after like 3-5 minutes the tablet will boot up showing the same boot error that can be skipped with pressing powerbutton. I checked sytem and it still showed "android 7 + EMUI 5" but built : BTV-W09C900B300
I think this is the one i "need" to be able to install the "HUAWEI MediaPad M3 8 Firmware %28BTV-W09 %2CC100B006%2C EMUI4.1%2BAndroid 6.0%29"
Problem is regardless which "update.app" i try to force install will get stuck at 5% and give me same error. I have ADB/Fastboot installed and tried some different things like flashing/unbricking it with "Huawei Multitool" where you can extract like boot.img or recovery.img and try to flash it.
Also getting an error. I can access eRecovery witout problems, the option to fix it by itself by wifi doesn`t work. I can´t access "normal" recovery and i think there is the problem (may got bricked while flashing Nougat?) I think its recovery problem, cause when i boot it up to the "half-installed" Android and go into setting "hard-reset" option i know it would boot up intoi recovery and would erease everything, while bootup it shows error "reset failed".
In fastbootmode i see bootloader: unlocked FRM: unlocked
I tried to install TWRP recovery with adb but get error: adb remote command not allowed
I downloaded like 15 different Android Versions 6+7 Emui 4.1+5 to try with force update but none worked, may i have to flash special version of recovery first?
I just want a normal version of android 6 or 7 i dont mind but at the moment with half working 7 "without" systemapps its a hardtime.
I hope someone can help me.
This isnt my first android device and im not a total noob i unlocked bootloader and flashed kernels on many other phones but with the W-09 where i did nothing special i dont get why "recovery got broken"
Thanks in advance
You haven't read other threads too well: more times people reported that the bootloader got locked after an update still declaring itself unlocked!
Second thing you have not found: the Nougat update consist of 2 packages and the second must be installed from TWRP.

thanks for your anwser, i read that so i also tried unlocking it "again" and it quotet it is also unlocked in adb. I also know that there are 2 packages. That you need TWRP i didnt know thanks so i am a bit smater now. I think i ll try "relock" and unlock it again might be the right way, thanks for the tip.

This is nonsense. Unlock, install the right TWRP then install the second zip package.

i cant unlock cause i dont have the code, on the huawei page i try do make an account and get the code by providing the necessary information.
I just uploaded a picture, i choose "before EMUI5" cause this is the only option i can choose "tablets". --> i choose "tablet wifi" , enter product model "BTV-W09" then the serialnumber i can see in setting: 28D6R17316XXXXXX but then i have the problem to input product id, it say i can get it through "Dialer" app (which i dont have in wifi model ) or the calculator. Problem is in my damaged installation there is no huawei calc, other calcs from store dont work (read that problem in other threats) I tried many apps from appstore to get a product ID but huawei site keeps saying wrong product ID =/
With the program DC Unlocker i am able to see a MEID i dont know if its the right one, i tried my luck with the Product ID Generator from Huawei but it doenst work. (device not supported)
It's very strange that it says bootloader unlocked if you have never unlocked...
And was very stupid to try to installl a beta release without before unlocking and taking a backup.
Exhange your device for a Nokia 3110!

yeah at this device i never touched bootloader, i didnt think it would become such a big deal , i didnt want unlocked bootloader or other recovery just newest android. Never had any problems with the "force update function" to come back to stock. I tried DC Unlocker but cant get further cause device need to get into manufature mode (thorugh dialer or calculator which i both dont have) i hope maybe i find one more way.
Did you ever find a fix
Did you ever find a way to fix this. I'm in the same situation. I even did a VPN on my router to give me a Hong Kong address for erecovery and that still didn't work. I have the exact same product. Like you I tried to various attempts to download a new recovery, but nothing works. Nice hardware, but some of the worst software/firmware I have ever dealt with since starting with the first release of Android on the HTC Hero.

I had mostly the same problem. I rolled back to 4.1 using the rollback and the actual 4.1 update.app. I think that puts you on C100 if I remember right. Tablet I have is C128 (USA) but no problem for this step. Get the Product ID from the calculator. Allow OEM unlock in the settings, then unlock it using the unlock code. Email yourself the unlock code because who knows if their website will even be functional next time. Alternatively you can extract the stock calculator from the update_data_usa.zip or whatever and try to use DC with 5.0. That second update zip does not install properly via the dload method, so a bunch of stock apps don't get installed. You can kind of hack it and flash it via TWRP but I didn't do it that way.
Or...you can use firmware finder to force an OTA from 4.1 right up to 5.0 (350), then take that last partial OTA to 351 after as well. The way to do that is via DNS in firmware finder. Find the Full OTA in firmware finder you want, send it to the updater by changing your DNS the way it tells you to, and when it does the OTA, everything will be properly installed basically the official way. Good as new. Flash TWRP to recovery2 and replace the erecovery. Keep the stock recovery as is. Install magisk. Golden.

Also, as far as the rollback, you need to do the first one (the C900 which is just a compatibility fix to allow rollback, previously used by beta testers I believe). Then you need to do the second one, the C100. If it is getting stuck, try downloading it again and be sure you don't have anything else in the /dload directory on either internal or the sd card. I had one on both at one point so maybe that happened to you. The C900 should be very quick but the C100 will slowly progress after 5% all the way around in several minutes.
When you get to updating back to 5.0, you can choose whichever region you want as long as it is a full OTA. C128 is USA and that's what I bought so that's what I picked. That gets you back in the right OTA update channel after that.
Hi guys,
I started as a novice and have learnt the hard way.
Has anyone tried rollback to EMUI 4.1 EU version on a US device (W09) and are there any problems I should be aware of?
I have had the exact same problem shared in this thread and have gone through the pain of finding a solution. My last resort is to rollback to 4.1 and restart the whole process.
@deV14nt: you suggested that when updating back to EMUI 5.0, I can choose the region even if my EMUI4.1 is EU version. How does this work?
Thanks in advance for your help.

Update to Android 8.0 Oreo

Hi all,
I'm on WAS-LX1AC432B184 and i can't update via OTA because "no update" and I think there's update as a friend of mine has the same phone but different build numbers as i needed to unlock my dual sim capability.
When i bought my phone i could only use 1 sim then i changed it to a dual sim. Can this be the reason why i can't get updates? The guy that did the dual sim conversion told me that i will be able to get updates as normal but i don't at all.
Please help me get the latest update so that i can enjoy the new Android – 8.0 Oreo
Hey there, by looking at your build number, you've got a 3GB RAM variant (LX1 instead of LX1A) Dual SIM (even build number) P10 lite on the global cust (C432).
The strange thing is the build number, stuck at 184 when Nougat arrived at B209/210 (Oreo is at B360/361).
Maybe you did some kind of modification (root, bad EMUI flash in the past) to the system so you can't receive official Huawei updates via OTA?
Have you tried clicking on the top right in System Update > Download latest full package?
Just some guesses here…
Probably, the you're huawei p10 lite dual is a branded? Usualy these models is the very slow for porting major release.

Hi zYoshi,
the download latest full package is greyed out... i have done a dual sim conversion in the past not sure if it was done correctly but i got it done... is there anyway i can fix this?
I want to get new updates for my phone to be honest.

Hi sham_1
I sent you a guide wrote quickly in DM (for anyone who might need it, I left it here).
One quick question, now you have an even build number, right? That means that you are on a Dual-SIM firmware.
I suggest you to follow these steps and maybe wait some weeks because I did something similar too while Oreo was hitting Huawei's servers, but I received it only a month later, when the IMEI finally matched my firmware (the IMEI has to be approved in order to receive updates, suggest to "check firmware availability" on Firmware Finder).
"Hey,
I'm not so experienced in Huawei modding, but I managed to debrand my device from C55 to C432, so maybe it's worth a shot.
•
Anyways, try this:
- Download Firmware Finder from Play Store
- open it and click on WAS-LX1C432
- search for builds like B210 (must be an even number and not an Oreo B361, otherwise you can brick your device) choose a FullOTA
- click on update via proxy/DNS, follow the steps on screen
•
The important thing here is to know if the phone grants you into updating with that build, then failing in erecovery (detecting an error, no brick) so that you can reboot with not updated firmware and do a standard System Update from the settings, that update will contain the same build that you've got installed, but it will be used to basically overwrite everything without losing any data, even thought I suggest you to do a backup.
•
Before doing any of the steps I gave you, could you please describe me what you did, what method did you follow?
•
In this post, I am giving steps that worked for me when I had a corrupted firmware, but your problem may be different from this.
Check also the HWOTA method (to solve the same problem but with the warranty void, I suggest to use it only if the above method doesn't work), search "HWOTA P10 lite" on Google for more info.
•
Hope this helps

Can I recover files like photo or videos from Xiaomi Mi 9t 6gb/128gb?

I just install MIUI 12 Chinese version beta, in the unlock of bootloader I lost all file, some got saved by Xiaomi account and other in Google drive.
There is a way to recover the rest of lost files?
I appreciate everyone who can help me
try restore software for windows, but honestly I doubt it.
beside it's your fault - when you unlock bootloader there are pop-up warnings that you will loose data if you proceed.
always make a backup if you do something related to firmware

Can rooted phone work? If they add the possibility to root this MIUI?

Downgrade question - possible upgrade upon restart?

Hey all,
I am very much willing to wipe my phone to do a downgrade.
I have the OP8 Pro, unrooted (never rooted/never unlocked bootloader).
The scenario I see is - I downgrade my phone to 10.15.13 (I have the INAA modell). I'm sure at some point the phone will check for an OTA.
My question - Is it all possible for the phone to upgrade itself if it restarts?
Meaning, is there a time limit that the update is sitting in the queue waiting for the user to press reboot to install? Or can I just somehow figure out a way to silence the system notification of an update pending?
Not sure if that makes sense but my hope is to just go back to 10 and enjoy certain things that just worked out better for me unrooted vs 11 unrooted until some things are ironed out.
Thanks for your time.
No you would need to initialise the upgrade, unless you have automatic updates on.
You would have seen the initial installation begin.
Least that's my experience of it. The update is stored on the phone so you may also be able to delete it.
Turn off automatically download updates.
I downgraded using the special firmware I found (couldn't find official to do it ) and then installed the official EU/UK firmware straight after with no problem
