Is it possible to relock bootloader without wiping data? All my previous devices didn't require wipe, but I received such strange warning when tried to relock bootloader on Z2 Force Sprint

I believe you're not able to relock the bootloader until Motorola release a signed bootloader. I had the page once before I'll see if I can find it again and add an edit if I do.

Don't relock your bootloader unless you want a brick. Technically you can relock it, but everything has to be legit. You've already voided the warranty, relocking won't reinstate that, all that will happen is you'll be bricked with nothing to do about it because you've locked the bootloader.
Why do you want to relock it?
I would like to relock my bootloader and wondering the accuracy of this last post. Will relocking my Sprint Z2 Force bootloader brick my device?
I'm running completely stock via OTA 8.0.0 no root. The reason I want to relock my bootloader is bringing my phone to out of box status and pass SafetyNet. I don't want to root to get this done and I want to continue receiving OTA's.
I understand that my warranty is void when I unlocked bootloader originally and I understand relocking my bootloader will wipe data (factory reset).
Will this brick my phone?
Can I relock anymore?
What are the fastboot commands to relock the Z2?
Thanks!

I would suggest flashing one of the flash alls for sprint before doing it to ensure being fully stock. The command is below. Also i f you ever have any issues and want to reunlock, you always can with your original unlock code.
"fastboot oem lock"
You'll get a "are you sure" message. Type in the command again and poof, relocked status.

So, I did a "fastboot oem lock" and it re locked the bootloader. Restart bootloader, shows locked. Restart phone and still getting a splash screen similar to the one when your unlocked but this time it says "Device has loaded a different Operating System". Continues to boot normally into the system without issues. This was odd so I unlocked again did a Flashall w/ "XT1789-03_NASH_SPRINT_8.0.0_OCXS27.109-48-6_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip" and "fastboot oem lock". Both times said the lock was successful. But I'm still getting this boot splash screen with test reading "Device has loaded a different Operating System". System boots but still fails SafetyNet.
What gives? What am I missing?
From what I can muster up on XDA I can see that "you need a signed boot.img". Does this mean something and how can I find this?
Can anyone who has unlocked and then relocked their bootloader report on the behavior of your phone? Do you get the same "different OS" splash screen? Has anyone been successful at making it go away and passing safetynet?

I've been working on this all morning trying a couple different methods. But none have been successful. But the best I can figure, when in bootloader, there is a message stating that your system is "Modified". Somehow, that needs to get changed to what I can only speculate as "unmodified", or something alike.
I tried 3 different versions of returning to stock
First one I tired I cannot seemed to find now
Secondly, I tired:

Posted by Uzephi
I added the command "fastboot oem lock" 2 times just above the fastboot reboot command; thus locking bootloader.
But upon reboot, I still get the modified OS message.
Lastly, I tried this method
https://forum.xda-developers.com/showpost.php?p=76850077&postcount=6
I downloaded https://mirrors.lolinet.com/firmware/moto/nash/official/TMO/XT1789-04_NASH_TMO_C_8.0.0_OCX27.109-36_subsidy-TMO_regulatory-DEFAULT_CFC.xml.zip
Followed the instructions (to some degree) and modified them for Linux since I am not a windows user.
After reboot, radio did not work. No WiFi, not data, nothing. Developer options was already enabled, but oem bootloader unlocking option was grayed out. Now I cannot unlock my bootloader and flash an updated OS.
Thanks for the reply! As of now I am stock latest Sprint 8.0.0 July update with bootloader locked. I get the "Your device has loaded a different Operating System" splash screen when I boot up with a "ID:" followed by nothing. I don't know what this "ID:" with nothing following this means. Also when I run a SafetyNet status app is says failed. But, everything else in the OS appears to be working. Google Play shows "Certified" status and all my apps that require SafetyNet is working (Banking apps, Netflix, Hulu, Google Pay, etc...). So I accomplished my mission in getting these apps working and everything else appears stock. The only thing that troubles me is this "Your device has loaded a different Operating System" splash screen and the failed status in the SafetyNet app. Would love to know how to fix this or an explanation on why.

That message appear because you've unlocked your bootloader before, I'm getting that message too and I can update my device via OTA. If you change that splash screen OTAs will fail.

Yeah, I was trying to find out if the phone could be reverted back to an out of back state. Another words, no splash screen saying "HEY! I HAVE BEEN MESSED WITH!" like you can on any other phone I have ever owned.
Thanks!
Yes you can

Yes you can , I already had this issue with my moto z2 force in Morocco , so what I did is I connected the phone to internet via bluetooth and when I added my google accounte the unlocking oem in dev option was normal , so I was able to flash roms again . Hope this will help you
I think there is no way to relock bootloader without wipe the device. Also you can relock the bootloader and you will not have any problems. I've already done it, at least with my sprint moto z2 force. the message there is no way to remove it, only flashing a logo.bin, "the boot splash" or replacing the logo.bin of the flash all package by the one of your preference.

Yes, you are rigth
So, which of the methods to re-lock did finally work? I was running on Android 8 before, OTA failes for at least 10 times, but suddenly it worked to upgrade to Android 9. Now I am weirdly not passing SafetyNet-check anymore (was working fine on Android 8, GooglePay etc).
Any recommendations? I just need the stupid GPay thing working
So I followed instructions on how to unlock bootloader on my pixel xl. And now I'm unable to connect to my network. I put the sim card in and it doesn't recognize it. I've tried multiple times to restart phone with no luck. So I did this last night and the only solution was to hard reset the phone once more. But that untenable that oem unlock function! So I unlocked it once more just now and I'm in the same situation! Should I proceed by unlocking oem and than do a hard reset? I'm not really sure how to proceed from here if someone could give me some insight i would really really appreciate it!!!

Are you saying that it isn't recognizing your SIM, and saying there is no SIM inserted, or are you saying that it's simply not applying the right APN settings and so you can't get cellular data and such
hi , its easy , just remove your sim card , and flash the phone again
Once you OEM unlock your phone a hard reset should not relock your phone. The only way your phone should relock is by using issuing the command OEM lock or OEM flashing lock.
There is an issue with some phones and systems where the "allow OEM unlocking" check box will come unchecked, this doesn't mean the phone is relocked though.
I got it figured out thanks! Now I'm just trying to install twrp but I'm not having much luck lol

You have to boot to TWRP from fastboot with the TWRP image file and then flash TWRP from within that recovery.
Hello
i am new here.
I got a Samsung A3 2017 SM-A320FL which is locked with a pattern. I need the files from the phone(contacts,images,etc...). No one knows the pattern. Is there any way that i can get the files before doing a factory reset. USB debugging is not ON, nor is OEM unlock checked. Cant flash custom recovery because "Custom binary blocked by FRP lock". The phone is working but i cant unlock it and i dont want to factory reset it because i need those files. Anyone got an idea?
Thanks
anyone, anything????

login to google dashboard with the google account associated with the device, or you can use the samsung account associated with the phone also.
Cheers
I waited the 72 hours and then ran the program on my PC for the Mi Unlock, and then afterwards I wiped the phone clean, flashed TWRP, and put on miui10, forgetting that doing a data wipe resets the Mi Unlock status. Do I really need to reunlock it, cause if so it will delete all my data again..
Edit: It's just odd because on the bootloader screen, 'fastboot oem device-info' shows my bootloader unlocked still, I have Magisk installed, running joeykrim's Root Checker from google play shows root access not properly installed, running flar's DevCheck from google play shows the device rooted, I have BusyBox installed , and lastly, in the Developer options, OEM Unlocking is ticked on, but doesn't say already unlocked, and the Mi Unlock status still shows locked. Lots of conflicting info here, so just a bit wary since this is my first Xiaomi phone.
I went ahead and tried unlocking again with the tool and I get this (see screenshot)
Usually unlocked only once, but if your device is locked again, it can be unlocked without any damage. Don't know what ROM you use If it is a world class ROM, ctf will not pass. For magisk, you have to modify the fingerprint to pass. Try studying. You have to do it. Good luck.

WEll everything is running fine being rooted. MAgisk SAfetyNet passes, rooted apps work fine, but Mi Unlock still shows my phone is 'locked'm but fastboot says it's unlocked. And I'm using the official miui_MIMIX2Global_V10.2.2.0.ODEMIXM_a92827160b_8.0 rom and fw_chiron_miui_MIMIX2Global_V10.2.2.0.ODEMIXM_a92827160b_8.0 firmware
You don't have to worry. I think your device is already unlocked. If the device is still locked, you cannot install twrp.
yeah thats why im confused. everything works fine. i guess i wont worry about it unless i come to a problem
