I am intending to sell my s22u and want to lock the bootloader. The buyer freaks out when they see the startup message.
Is it possible and what's the command?
Also, will it wipe data if possible to lock it?
Follow the same process you used to unlock it. Locking the bootloader does wipe data.

Just received my Solar Red U11. Is there any reason not to unlock the bootloader right away?
I'm not planing on rooting it or installing any custom ROMs anytime soon, but I'm also not 100% sure I'm gonna be keeping the phone (few things I need to see if I can get used to).
Should I just unlock it now so I don't have to (potentially) wipe my device at a later date?
Thanks!

if you decide to unlock at a later date you can back up your stuff to your computer unlock then put it back.all the other stuff is your choice, me, mine is unlocked out of the box.
it only wipes your internal, not the ext_sdcard
At some point, one of the future updates could prevent you from unlocking it. That would eliminate the
ability to modify your phone's software. If you'll never do that, probably doesn't matter if unlockable.
The only downside is the orange reminder splash screen that is displayed on boot-up.

Aldo, how do you back up data & /or app settings of 3d party apps fm a device w/locked Bootloader & no root?
Also, what & how much boot delay is there if you unlock bootloader - I saw someone post a pic that shows the screen in text mode & a warning abt startup not beginning for 5 seconds.
Also, please clarify, HTC gave warnings about losing the Fingerprint capability if you unlock the bootloader; I just want root,so I can run Titanium B/U & some root-needed apps- put really like the Fingerprint feature- was that an old warning? The posted HTC warning says you can'telock the bootloader- but I just saw someone talk abt re-locking their bootloader bc they want to sell the device as clean.
Any help much appreciated, TIA oldwolf
Boot loader won't effect your fingerprint scanner....never heard of had that.
The warning about losing fingerprint scanner functionality on HTCDev refers to the One Max (2013), and only to that device AFAIK.

Go to developer options ( on setting) and allow unlocked bootloader ,,,ok finish
Unlocking the bootloader has no adverse effects. You can still update ota. If the bootloader is ever unlocked there is no reason to relock it unless you are returning the phone to the store.
I just unlocked the bootloader to install twrp and maybe magisk i wanted to also try the Android P dev preview. but i know having a unlocked bootloader is a security risk also your get that warnign message at boot which makes booting up longer,is there a way to lock and unlock without losing data if im root.
Unlocking and locking wipes all data by design.

Is there a way to make the device secure with it having a unlocked bootloader?
With an unlocked bootloader, anyone can install a factory image, which wipes all your locks and your google account (and, therefore, defeats FRP), which is what makes it insecure. The only way to avoid that is to have a locked bootloader (and USB debugging off). (And I've seen reports here that unlocking the bootloader, installing TWRP and Magisk, then locking the bootloader, results in a hard brick (meaning buying another phone, because Google won't replace it)
Run with the unlocked booloader, don't ever leave the phone off your person and have "insurance" that replaces stolen (and possibly lost) phones.
I've been planning to unlock my bootloader to install TWRP and GSI's on this device but I've seen the warning message you get every time you restart the device. I have plans to sell this device in the future, so I would like to know if there is a way to relock the bootloader or remove the warning message on startup. Thanks.
Yes you can relock the bootloader, the process is done the exact same way that you use to unlock it. The warning message will be removed and you will only be able to flash stock binaries.
But for Samsung phones specifically there is something to note, there is something called an "E-Fuse" that will be "tripped" when the bootloader is unlocked for the first time. There is no way to revert the phone back to a pure factory state after this happens. The feature is called Samsung Knox and it prevents a few (Samsung based) features from working.
You can read a bit here - https://en.wikipedia.org/wiki/Samsung_Knox
I know about tripping Knox. I don't really care about not being able to use Secure Folder or S Health so it's not an issue for me. My main concern is to remove the obnoxious warning when booting the device as it can be intimidating to a non savvy potential buyer. Anyways thanks for the reply.
As said in the title, I want to root my phone without wiping it, because, well, I don't want to spend a ton of time setting it up again (you can't backup installed apps)
No you absolutely can't. When you flip oem unlock and fastboot flashing unlock it automatically factory resets device. No way around. I did from the get go so I had original data.
it is so sad that in order for you to root the device you have to unlock MI UNLOCK STATUS. in order for you to unlock it you have to wipe all data. Is there any other way to root the phone without wiping data? anyone have other method to share? thank you
No.
You need to wipe all the data.
Is there any other way to install custom rom aside from starting request UNLOCK bootload from Xiaomi as 1st step?
I don't care if wipe all data or everything, I bought it not long ago but just found out how ridiculous it is that we owners have to request for unlock.

No.
You must unlock the bootloader to install any custom ROM in every device, so the UNLOCK is required.
