Does Bootloader unlock operation really wipe your data? - Redmi Note 9S / Note 9 Pro (Indian Model) Question

Hi gentlemen,
i'm posting here because i could read on the web different points of view from Mi users. Some tell they didn't get their data wiped after unlocking their bootloader while others tell they had.
I guess it depends of devices and version of os they wore.
So what is about us with Redmi Note 9S (i've got MIUI global 11.0.8)?
Second question: In case it wipes, is it possible to make a full backup of the device without root and TWRP?
Thank you for your answers

Redmi Note 3 32GB Mediatek version - unlock bootloader

Hi, I need help. My girlfriend bought a Xiaomi Redmi Note 3 32GB / 3GB RAM Mediatek Helio X10 version.
I want to upgrade the firmware because it needs an upgrade. Since she bought it, February, it didn't updated one single time, and it has some bugs that upset her. So, here is the problem.
I already asked for permission from Xiaomi to unlock the bootloader, and already got it. When I tried to unlock, got the 50% problem (Current account is different from the account info on the device). Since then, tried to flash (from the Updater App) the developer ROM, also with no success (couldn't verify package).
The last option, I believe I have, is to manually flash (using MI FLASH software) the developer ROM and after that, unlock the bootloader to finally install the MIUI 8.0 (that's the goal of all this, with the unlocked bootloader).
So, how can I do this? Suggestions, tips, tutorials, guides or experiences, everything is welcome!
You have to go to latest Beta/developer Version and the Unlock should work...
Else just Update miui, because maybe the Bugs are fixed

I already solved it by 'hard flashing" the miUI 8... because that's the version she wanted. Didn't try to flash the miUI 6 [developer] because I was lazy, but mainly because I didn't see any gains for her from doing it [unlocking the bootloader].
Thank you 2 for the replies!
Hi Guys,
I've been searching for 2 days now for a clear guide on how to unlock the bootloader for the Mediatek version and haven't found anything other than the official way. Can someone point me in the right direction please?
Thanks.

[Kate / SE] Very confused about modding ... I need help...

... sorry but I'm very confused ...
I'm reading the possible on the network, but the result is I always get confused more despite having a certain familiarity in modding having modded a galaxy nexus, and an LG G2 on which I installed TWRP recovery and various CyanogenMod ROMs.
Unlocking the bootloader in kate/SE, in an official or unofficial way, is still very difficult or almost impossible?
I often read of modified TWRP recovery, which sometimes give problems and sometimes it does not ...is it possible just put the official TWRP for kenzo?
If I can somehow install a TWRP, is possible to easily install the CyanogenMod ROM (after flashing ROM flashing kate modem is needed) and provide CM updates simply by flash new ROM via TWRP recovery?
Thks in adv
Nope! It's easy as 123... Please, check:
http://en.miui.com/thread-345728-1-1.html - for unlocked "emmc_appsboot.mbn".
You can also download ALKA TWRP, rename to "recovery.img", and replace it in fastboot ROM (image folder).
(As well as "emmc_appsboot.mbn emmc_appsboot.mbn", downloaded from the link above.)

I could not unlock my "kate" officially.
I've tried the method posted above, and works like a charm!
No bootloop, at all...
Thaknk yo so much for yr reply
I remain with the feeling of more complexity and less certainty, than the modding of the galaxy nexus and also the LG G2...
Official unlock works fine.
I have a Kate and unlocked it officially.
Just make sure to flash the global developer ROM, log into your MI account on the phone and press the "bind device to account" button inside the security settings menu before attempting to unlock.
I also got my Kate to unlock officially after using updater on phone to flash global beta rom.then in developer options clicked MI unlock status then linked phone to account. After that unlocked first try after many many failed attempts on global stable.
Nice news and info, thks so much!
But... why so many people can't officially unlock their kate having 50pc error...??
Which version of miui unlock tool and Global Dev. ROM you used when officially unlock yr kate?
I used global beta 6.11.24 and MIflash unlock_1.1.1111.1_en
Thks for reply and info

Need help with TWRP recovery install and/or root redmi note 4x bootloader unlocked

Hello,
I have been trying to install TWRP recovery in my bootloader unlocked xiaomi redmi note 4x phone with china stable ROM non-root device. I have tried multiple methods that I found in this web and somewhere else but unfortunately all failed and unable to install any kinds of recovery. I am also trying to root my device but failed every method I found. One main problem is I don't read chinese at all and my ROM is chinese version. I have been trying to install at least Global ROM so that I would understand english version and probably able to root my phone and ultimately use google play store. None worked so far for me.
I would really appreciate if you can help me resolve any one of my issues stated above.
Thank you very much

The language of chinese rom can be set as english.
Then you can flash chinese dev rom and use a built-in ROOT.
However, without twrp you can not flash gapps because the system part is encrypted, so you must unlock the bootloader and then flash twrp.

Miui Stable vs Developer

Hi guys,sorry for this stupid question but after the xiaomi's news about the bootloader re-lock that causes a brick...i'm not sure of anything...so i'im asking this
I bought a mi8 6/64 global version(bootloader locked) so i think that is coming with the global stable.
So if i want to put the global developer can i just download the package from miui website and then install it from.the system update settings on the smartphone without problems?
Like bricks,errors or something weird? ?
If yes...afyer that,can i come back to the global stable without issues?

Sorry but i can't find the answer to my question.
Ok for unlocked bootloader and china/global.
Ok for anti rollback for android 8/9.
But my question is about a Mi8 with locked bootlader and Global stable and developer
xandreasx said:
Context:
Over the few months i have seen many Mi 8 owners who tweak their phone end up with a bricked device, of all the cases, a huge majority of them is due to the lack of research and jumping into modifying their phones before fully uinderstanding the situation (I almost made the mistake too, taking for granted that all android phones have minimal restrictions)
There are two things to take note of (especially if you decide to tweak your Mi 8/SE):
1. Xiaomi implemented a policy that prevents relocking of bootloader if you install a Global Rom on a China Variant Mi Phone
What this means: You cannot relock bootloader if your Mi8/SE is a China variant and ou have Global Miui version installed (Developer/Stable)
Common mistake(s):
1. Avoid 'Clean and lock' option when using Mi Flash. Only use 'Clean all' or 'Save user data' option
2. Do not relock your Mi8/SE if you are on Global Beta or Developer or Any MIUI rom that is Global
2. Google implemented a policy that prevents rollback to older Android versions for Android Oreo and above Roms. This is for 'Security' reasons and affects MIUI.
What this means: You cannot rollback to an older Miui version (Below Android 8.0) if you already you are currently on Andorid Oreo (i.e Miui 10) and up.
Common mistake(s):
1. Do not restore an old backup with Miui that has any Android version less than 8.0 from Miui 10 ( Android 8.0)
2. Do not install Miui 9 (Below Android 8.0) after installing Miui 10 (Android 8.0 Above)
*Tip: Ask yourself if the Android version you are about to install is lower than the Android version currently installed, if it is, DO NOT flash it. (Applicable if you are currently on Android 8.0 and up)
Please keep all of this in mind before you start tweaking your phone as you will run the risk of bricking your Mi 8/SE. After which, your Mi 8 becomes a very expensive paperweight. I hope this helps to clear things up for many people! Do know that while I disagree with Xiaomi's new anti-consumer policy, i also feel that it is YOUR responsiblility in your own actions, especially when you decide to modify your device and when you do modify anything (not just phones), there are always risks involved. When in doubt, it does no harm to Google it or just ask around in the forums. Moral of the story: Proceed with caution!
For those already bricked:
1. Contact Xiaomi Customer Service and try obtain edl permission to peform Testpoint fix.
2. Bring your phone to a Mi Store and hope that they can help you with it.
*In the case where my information is wrong, please correct me so that I can update accordingly for the benefit of everyone!
Have a nice day ahead and all the best in your phone tweaking adventures! Hopefully I helped you in clearing things up

I have the bootloader that is locked and i would like to leave it locked.
Then, is it possibile to change rom from GLOBAL STABLE to GLOBAL DEVELOPER without unlocking the bootloader and making other "modding things"?
Then(only if the 2 roms have the same android,so not now) can i switch back from DEVELOPER to STABLE (with locked bootloader and only if they have the same android version)?

I see what you mean, so yours is the global version and you want to flash without unlocking, http://en.miui.com/thread-720781-1-1.html (google search). Yes u can, from my personal experience, upgrading shouldn't require data wipe, but if you downgrade be prepared to wipe data, thats the only drawback, but you can definitely do it without a bootloader unlock using XiaomiTool or Miflash as well. For upgrading to developer just use updater app and select package, if not possible then miflash. Be careful flashing, you shouldnt have any problems as of now as long as you stay away from China rom. Miui roms are all ARB:1 which means ARB not yet activated, so downgrade possible. Have a good day ahead and have fun with your new Mi 8, it is a great phone (apart from the EDL lock **** Xiaomi pulled)

you can switch from global to dev with locked bootloader. Just download the dev of Android 8.1 and install it via settings - choose package, this will format the phone. Then you will get the Android 9 8.11.8 update

Perfect!

Maybe for the "normal" XDA users it's too easy and obvious...but not for me xD
Sorry guys if i bother you again.
But someone just told me that, yes it's possible to change from global stable to global developer but that i should have the same Android version (in this case right now stable is 8 and developer 9).
Otherwise i should unlock the bootloader and then i can switch...
What do you think?
Download http://bigota.d.miui.com/8.9.7/miui_MI8Global_8.9.7_fb7963a71d_8.1.zip and install it via phone updater.
That ROM was the last beta Android Oreo published.
After installing it, you'll receive an OTA update of the current beta ROM 8.11.8 Android Pie.
Done.
Hi xandreasx,
did you do it? Did it work? I tried and it did not work. If it worked could you send me the link where you downloaded it?

You can keep your data only if you do a backup before switching to beta
I have global stable 10.0.3.0 on global mi 8, locked bootloader. I downloaded 8.9.7 Global dev but the updater app says that it's not allowed to update to an unofficial rom. What version of oreo global dev do I have to flash?

What's the state of the Mate 10?

I just got a Mate 10 and I wanted to know the state of the phone before touching anything: just a quick summary.
Do you have to unlock the bootloader to install stuff like TWRP? I wanted to at least root it to install Titanium Backup and remove a bit of bloatware. If so, can anyone share the latest tutorial? I've seen lots of them but I don't really know which one is up to date
Is it advised to install a custom ROM or is EMUI good enough? I was previously using a Redmi Note 3 with MIUI.
Is it known if this phone will get Android Q by any chance? Just curious
Thanks!!

Well, for me EMUI is very ok. I have a Mate 9 and Mate 10 Pro.
I used to flash custom ROMs on weekly basis (LG G2, G3, V10 & G5). Maybe it's laziness or the volatile nature of Kirin SoC and its difficulty in flashing but I've decided against doing it.
Bottom line is that I'm more than happy with EMUI especially 9

First question
-yes you have to unlock the bootloader in order to root phone( not recommended if you not sure what you doing because of very easy hard brick possibilities)
Second
-custom rom or Emui that is up 2 you, you like or don't like Emui and
Third
- Android Q is far far far away so IMO that is highly unlikely
Thanks!
I'll stick to EMUI, it's great so far and I don't want to mess anything up.
