[Q] Relocking Bootloader after installing Cyanogenmod?

Hey gang, trying to make sure I won't run into any nasty surprises before I attempt this, so;
I want to install the Unofficial Cyanogenmod ROM for the Mi 5, move away from Miui - but I also want to regain Android Pay functionality (and a few other apps I'd like to use that require a 'secure' device). For that, as far as I know, I need to relock the bootloader. So basically I'm looking to have my device that is:-
• Rooted
• Running custom ROM
• Custom recovery
• Locked Bootloader (or at least Android Pay functionality)
Installing the ROM and keeping the recovery updated and working isn't a problem, but I just want to make sure that I won't bugger something up when playing around with the bootloader. I've never had a device that's needed a bootloader unlock before, so I'm very tentative around the whole idea.
Is there anything that I need to know about relocking? Such as specific quirks with the device (I've read people have found themselves stuck in boot loops after locking) and if it's even possible to do so with a different ROM installed.
Thanks in advance!

Don't lock bootloader again, usually it causes issues(been there, done that).
But Android Pay doesn't require a locked bootloader, just unmodified system.

bootloader

Is it possible to unlock?

At this moment, no.

You will know as it'll be reported here very early. There are some third party companies that do it. Some are cheaper than others.
For the moment, there is nothing..
Sucks I know

I asked this before on another similar thread and didn't get a response. Is it possible to dump the bootloader from either an unlocked or locked phone to analyse it for potential vulnerabilities either in how it handles the unlock code, or more generally that would allow a user to soft-mod unlock the phone? I know for the 5th, 7th, and 9th gen Fire 7 tablets exploits were found in the LK part of the bootloader which eventually allowed for a customised version of TWRP to be flashed onto the devices, and later LineageOS. If we could dump the current Huawei bootloader surely we could try to find if there are any similar exploits?

I am found metod but it needs mrt dongle((

Tbh custom roms aren't really important anymore. Google is already ruining android everytime a new update comes around, like the overlay feature that was introduced in oreo but then removed for no reason.
Besides EMUI is already optimised for the chip so, again, no reason for custom roms and/or rooting (unless you want to remove bloatware but that can be solved via ADB)

Question Question regarding root and updates?

Hey there guys,
I just received my s21 ultra (G998B) and planning to root it. I had a few questions since I’m new to this and wanted some clarifications:
1) If I root the phone can I update it OTA through the settings or do I have to update it by another method? Will I lose root/data/apps if I do that?
2) If I lose root when updating it, can I just root again and be all set? Or do I have to follow another procedure for that?
3) I am planning to debloat a few apps and services that I won’t be using, if I update the system/software will the stuff that I debloated come back and will I have to do the debloat again?
Thank you for all the help.

1- Probably not usually the root or recovery will block OTA updates from installing, even if they download.
2- If you lose root, you can USUALLY re-root assuming the same root method wasnt patched. If it was patched, a new root method (though probably still through magisk) will be needed. If this is the case, its up to the dev to find that method, you might be without root for a while.
3-if you debloat, and receive an OTA, your will probably need to de-bloat again, thought I havent personally had experience with this.
Why are you rooting? Just to de-bloat? If so, root isn't really necessary...

As someone who's been in the rooting stage for many years, i can answer your questions.
1. You can not update your phone through OTA updates after rooting the device, as the device was modified in an unauthorized way. And since you own a galaxy phone, the e-fuse within the motherboard will blow and knox will be permanently blown. You can no longer use samsung pay, google pay, and any other app that uses the safetynet api, even after you unroot the device.
2. You will lose root every time you update. You will need ODIN on your PC in order to properly update your firmware and to re-root your device by following the procedure again that you used to root your device, unless samsung patched the method you used to root your device. You can always check what bootloader version you're on within the firmware. For example, on the galaxy S8, the firmware version is N950U1UES5CRG9. The 5th to last number of the firmware will tell you. In this case, N950U1UES5CRG9 is the 5th bootloader version. Keep this in mind once samsung starts to update your phone often.
3. You will have to debloat again from scratch. In order to fully update your device through ODIN, you need to download the full firmware file containing an AP (Firmware), BL (Bootloader) , CP (Modem), and CSC (Carrier File) and manually flash them.
Do keep in mind, it is possible to soft brick or even hard brick your device, so back up your data frequently if you decide to tinker with your device.

Thank you for the detailed answer. I just updated my software to the latest official one by Samsung (April 1st security patch) but I am not rooted yet. I guess I could live with the fact that I can root the phone now and stay on this software version/security patch until I upgrade, since I would have to go through a lot of hassle to set-up the phone the way I wanted. But the main reason why I want to get the official updates is because of the camera improvements that Samsung does, since the main reason of me getting this phone is the camera. And there are some root-required tweaks that I absolutely need such as Viper, and some xposed tweaks also. I like the Stock ROM of Samsung, it really has come a long way at least imo throughout the years, as I have been a Samsung user since day 1 but:
Would it be a good idea to install a custom ROM then? I am reading the description of a few custom ROMs and it seems like I can “retain everything” by simply dirty flashing the ROM and following the dev’s instructions on how to retain root whenever the developer updates it. Is that a better route to take you think? I can keep my device rooted, and still get the updates through a custom ROM.

That really varies depending on the custom rom you go for. Usually when you dirty flash a rom, you would need to re root your device, but some (not all) roms are persistent with root after system updates. Do keep in mind if you switch to a custom rom, your system might be more buggy and crash more often. One thing i will say though is that xposed is outdated. The last android version xposed officially supported was either 8 or 9. When it has to come down to certain mods you'd wish to have with root, take that into consideration too, as it might make your device really unstable if it's too outdated or if there's a buggy port available. I've dealt with that issue too many times on my phones.

if xposed is outdated, what is the new thing the comunity is migrating to? All the privacy, security, and customizability tools available through xposed must go somewhere, right?

There's buggy ports thats flashable on magisk. While you still can get xposed, it'll be an unofficial version, and more likely to run into issues within your rom and daily use into your device.

I mean xprivacy on xposed was the must have killer feature for any android device to turn your device into anything other than a privacy nightmare. If we can't do that any more we are f'd.
[EDIT] Looks like the new version of xprivacy, xprivacyLua is still supported for android 11, with magisk and EdXposed or LSPosed:
[CLOSED][APP][XPOSED][6.0+] XPrivacyLua - Android privacy manager [UNSUPPORTED]
XPrivacyLua Really simple to use privacy manager for Android 6.0 Marshmallow and later (successor of XPrivacy). Revoking Android permissions from apps often let apps crash or malfunction. XPrivacyLua solves this by feeding apps fake data...

Bootloader Xiaomi Redmi 9

Hello to everyone reading this, wish you all the best in the New Year.. Now let's get to the problem I have.. I'm using Brave as my browser and I am sure most of you are familiar with Brave Ads, well they don't work on my phone.. While duckduckgo-ing through I stumbled on possible reason why it may not work, the said reason was unlocked bootloader.. It was suggested to download SafetyNet test and check if everything is as it should be. To my surprise my bootloader was unlocked (I double checked via developer options since Xiaomi offers information on that there as well) but the issue is I never flashed any ROM or Firmware nor anything similar, it's stock as it can be from the store.. Now that I elaborated the best I can (Since my native language is not English) I need to ask 3 questions as stupid as the may sound.
1. Is it possible that bootloader unlocked by itself or some shady app?
2. Does that lock icon below front camera unlocks bootloader by tapping when you turn on the phone? (Since it was locked before and now its not)
3. Is there a way I can lock it without using PC and adb tools?
Thank you for your answers and time, much appreciated!
PS: I would add pictures if needed but since I didn't tamper with the phone nor change anything in developer options I doubt it's of any help.

To lock the bootloader in mi you need to flash the stock rom and if you only need to pass the safety net checks install magisk canary and it's not actually possible to unlock an mi device without the authentication of Xiaomi so it can not unlock by itself as far as I know. Are you totally sure you or someone in your family or friends didn't unlock the bootloader because if not this may be a dangerous exploit used by a shady app and should be reported to Xiaomi now.

Not a single soul have a access to my phone, and if they did they sure as hell don't know hot to flash custom roms or unlock bootloader.. So it might be some shady app.. But how would I check and see if that is true?
PS: And about magisk canary I don't see it in google play store, but I suppose that is apk for rooted phones? The issue is my phone is not rooted if that is the case.

Question Consequences installing custom ROM [SPES|SPESN]

Hello,
I would like to list the consequences of the changes when installing a custom rom on the redmi note 11 (spes/n).
In your opinion, what causes the following changes on our phone
This is some responses I can give after testing myself
1/ Unlock bootloader
Erase all your data
The unlock icon appears on the top of starting logo
2/ Install custom Recovery
Nothing have happened
3/ Install custom Rom (for me Evolution X)
First install : You will have to erase all your data
Upgrade : Nothing should happen
4/ Root
Maybe Unauthorizing Bank apk ?

Hi Darkspirit66,
Whilst I am not at the Custom Rom'ing stages yet with this phone, too new for me to tinker with this one... I'll just have to settle with me other phones for messing around with for now...
However I am glad you've raised these points. Whilst I've asked this before in another thread, its good to have clear answers...
Whilst most of the earlier questions, I kinda of expected. Some kind of message/logo at booting stage to announce it's unlocked/modified. I believe this is standard in pretty much all phones, one way or another.
Unlocking Bootloader/Flashing, again.... erasing of the data is standard practice again.
The bit that most concerns me... Is there any tell tale signs of after unlocking/rooting....? I've come from a mainly Samsung background. In the early phones, you simply ran "TriangleAway" and bob's ya uncle... no one is any of the wiser. Under new models, once ya trip the ole Knox, there's no going back. Permanent visible sign of tinkering, and security and bank apps will never work again without tricks.
So, if one was to unlock the Bootloader, root, rom and then change their mind and go back to stock. Will all the banking apps continue to work, or does it alter it for good....? I believe once unlocked and with custom recovery, its best to flash stock with TWRP as you get to keep the unlock but can flash stock and custom as much as you like without any triggers...??
Cheers, Lister

Hi LOS
Rooting the phone results in the problem with banking applications.
If you decide to unroot (it's possible) and reinstall a stock rom the apks should work again. (To confirm)

You can always hide root with magisk and keep your phone rooted also with banking apps ;-)
