Some questions about unlocking bootloader - Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers

Hi, I would like to know the answers to these questions that I asked to Xiaomi, and they didn't keep to respond.
1.When I unlock the bootloader, i will still getting MIUI Updates?
2.Installing like a custom recovery (like TWRP) will affect on any functionality of the device? And the custom recovery is gonna stay if I get a system update?
3.If I want to root my device (with Magisk), I heard that some devices, lost their Fingerprint scanner functionality. I'll loose it to? And at the moment of a system update, the root can be deleted while a system update?
4. Wich functionalities I'll lose when I unlock and/or root mi device?(other than loosing the device finder functionality and some more)

For one, Widevine security level will "downgrade" from L1 to L3. I know it's a magisk module that allows you, presumably, to unlock L1 level again but I don't know if it works.

[Q] Unlock bootloader vs root

Hi,
I'm about to jump on the wagon and get a Z3 Compact to replace my Nexus S. My Nexus S is long overdue and the Z3C would be a significant upgrade.
My Nexus S is rooted and the bootloader is unlocked. Of course, I have found the appropriate rooting procedures and unlocking bootloader topics for the Z3C. I would like to at least root the device to get Titanium Backup and the Xposed Framework. I have some questions however :
Are there any issue to just root the Z3C without unlocking the bootloader ?
I understand the unlocking the bootloader will cause issues to some functions due to DRMs security keys. Is rooting causing any issue on the Z3C ?
Is it possible to still receive Sony's firmwares updates OTA after rooting ?
Thanks
Neo.

Nope.

Nope. There is a way to root Z3 compact without losing DRM keys.
Is it possible to still receive Sony's firmwares updates OTA after rooting ?
Yes. You will still get the updates. However if you have a custom recovery installed or something modified in the system folder, the update verification will fail. Thus, rendering the update function useless.

Thank you sir. I have unlocked my bootloader on my Nexus S, however I am installing custom ROMs on it in order to have KitKat. But I don't see any benefit into unlocking the bootloader of the Z3C at the moment, since it should be supported for some time. Unlocking the bootloader just gives the ability to install custom roms, correct ?
Could something like Xposed Framework (which does not require bootloader unlocked, but requires root) cause an Android update to fail ? I do think it is modifying stuff in the system folder, however I don't have a lot of knowledge into the Android architecture. I guess I could just revert every Xposed plugins, upgrade and put them back (if supported by latest firmware).
Again, thank you

Yes. It could also be the reason why. I am not 100% sure on the technical details but based on my reading, OTA performs integrity checks (could be hash checks) on the system files before applying the update. Meaning if one system file fails to match an item, the OTA will not install itself. Also, I read that custom recoveries are one of the causes for failed OTA installation. In my experience, after I downgraded to KitKat and root it using Giefroot, I successfully installed OTA for the .77 firmware. However, during this case, I still don't have Xposed and custom recovery installed.

Questions regarding rooting & Unlocking BL

Used to root etc on old phones, taken a long break from it all but I have sent a request to Huawei to get my unlock key for my P10 VTR-L09C440, however I have a few questions I hope can be answered.
1. Can I re-lock my bootloader after unlocking, and if so does it say anything like "bootloader relocked" or anything like that or is it completely back as it was?
2. Can I use restricted apps (I know I couldn't use Barclays and I think one of my betting apps and Google Pay were restricted), has this changed now or can Magisk etc actually hide BL unlock / root / whatever it is it doesn't like?
I would like to know that too

1. No, when you manually relock, the bootloader status is "RELOCKED". To lock the bootloader you need to use HWOTA8, FunkyHuawei or FirmwareFinder and update to the newest version. Both will cause factory reset.
2. When you rooted with Magisk most apps with Root detection will work, when you enable "Magisk Hide". I use it on my bank secure tan app and Mario Run without any problems. Some friend are using Magisk Hide with other banking apps without any problems, too.
I haven't rooted and unlocked myself but I read about an important part of the process.
First of all you have to enable oem security in developer options, otherwise you risk the FRP lock.

If I'm wrong, someone please correct me.

OK great, thanks for the info. I have actually finally just heard back from Huawei so code should be imminent. Unfortunately my battery as stock seems to be awful so I need to try something to make it last a day at least.
Does Magisk hide make Android Pay work too?
I think I'm right in thinking that banking apps and the like often check bootloader status rather than just root. I assume Magisk doesn't hide this?
If I go back to stock and relock bootloader, will the apps also still register that the bootloader has been unlocked and still not work?
TIA

Can someone confirm this please? Does anybody use Android Pay and Barclays confirm Magisk makes it still work with Bootloader unlocked?

Oreo bootloader unlock and root questions

I have a p10 vtr-l09 8.0.0.327(c654) security patch nov 5 2018. I live in Canada and am getting sick of these Amber alerts waking me up at all hours of the night. (In Canada all alerts are sent as presidential) So I want to root and remove the cell broadcast apk. I have not done anything with this phone as of yet. I have rooted all my other phones to date. I got my bootloader unlock code from huawei before they stopped giving them out. My questions are as follows. 1. with my security patch level at nov 5 2018 will i have any issues unlocking my bootloader. I saw people having issues with unlocking the bootloader and using dc unlocker to get the code. I assume because i already have the code i should be fine? 2. After unlocking and installing twrp is magisk the best or only method of root? 3. After installing magisk removing the desired apk , is removing root by magisk easly done? . 4. Lastly Do most leave their bootloaders unlocked? I have with my sony phones in the past, just wondering. Thank you
You don't have to unlock bootloader to uninstall app. Only root will do. Do something like kingroot, and then uninstall unwanted content trough app. Of course be wise and think before what do you wipe. Some core and google apps are inportant for funcionality.
Is it Posible to Downgrade The Huawei P10Lite anyway to Root it and unlock bootloader than?
I need to install Custom Rom on P10Lite the Stock Firmwire is Sh**!!

Does kingroot modify the system partition? Reason being is I don't want to have Google's safety check flag it so I can't use specific apps. That's why I was considering unlocking the bootloader flashing a custom recovery and flashing magisk. I guess what I'm looking to do is either a hidable root, or a root and remove APK , then unroot. Banking aps are my concern, I don't want to root then not be able to use them. I used root cloak with xposed to hide it before. Not sure if it's still an option

Does Kingroot work with Oreo and unlocked bootloader? Is it how you got it working on your phone?

Xiaomi Mi9 unlocked bootloader - what does it really mean

Hi guys,
I've recently purchased my first Xiaomi device, the Mi9. I'd like to install the xiaomi.eu rom and thus have to unlock the bootloader. Now, whats does unlocking the bootloader really mean? Do I lose some of the native functionality of the phone (find the device, fingerprint, high level security apps such as banking apps, etc)?
I can't really find no specific info about that. As far as I know by unlocking the bootloader no varranty is void. Is this info right?
Sorry in advance if my question may sound noobish but it is my first Xiaomi device.
I think you lose Widevine L1

Question Updates about Realme 8 pro modding options

Hi all, i don't follow modding world from a while so i don't know what happened more or less into the last 3 years, so now that i need to root the device i wanted to do some questions.
I bought a realme 8 pro at the dayone and now i have the last update installed (so realme UI 4.0). I wanted to do the root but i don't know how much realme support it, if the bootloader is locked or not, ecc. ecc.
I saw in this phone thread that there is a method (the guide is written in May, 14 so it seems very recent) about unlocking bootloader (so i guess is locked?) using deeptest, i tried to read but i didn't really understand what kind of thing is that. So i wanted to ask, what is deeptest? if it is locked, if i successfuly unlock this bootloader what happens to AIO updates? (I guess there will be no updates such as other devices?). If the AIO updates stop to work, Is there a way to manually download and install updates? Can i root this device using magisk for example? I have seen there is something, but there are these things i can't understand.
Thanks in advance for replies and sorry for my bad english.
Hi, yup, the bootloader is locked.
Deeptesting is an app by realme used to request an unlock code. You can try this one https://forum.xda-developers.com/t/unlock-bootloader-help.4425415/post-86777721
Try submitting your application, if it tells you "Your model doesn't support deeptesting" you'll have to follow my guide.
Either way, after a bit of waiting, inside Deeptesting → query approve result → start Deeptesting.
Doing this allows your phone to boot into fastboot. Where you can unlock your phone using
Code:
fastboot flashing unlock
Unlocking the bootloader will wipe your data.
Hi, thanks for the reply! So there is a method to unlock the bootloader. But if i do it, i can't update anymore my device via OTA, right? How could i do that thing. In addiction, is not possible to obtain root permission without bootloader unlock? Because i need root to save whatsapp messages 'cause the application is stupid and can't do a backup by itself.
In addiction... I downloaded deeptesting and my phone does not support it. Yeah
You can get OTAs if, and only if, you didn't modify the firmware. Unlocking itself doesn't break OTAs, but rooting/custom kernels/vbmetas etc. will.
You can't get root without unlocking. As per Whatsapp, I think you can use ADB to back up data without root.
Thanks again. As i know ADB is disabled for whatsapp from a while. Ok then, thanks anyway for all informations. I guess after the bootloader unlock i can install magisk to obtain root acces.
