Hey everyone,
My nexus 5x froze shutdown yesterday.
My phone uses TWRP and Cyanogenmod. After it happen I couldn't even boot into *recovery* ! The phone just "turns off" and I cannot turn it on for quite a while.
Eventually I was after to get into bootloader to use fastboot.
I tried to reflash the recovery. The flashing worked but I still couldn't boot into recovery.
I read somewhere someone who wrote that he/she locked and than unlocked the OEM lock and it worked for some reason, so STUPIDLY I locked my OEM, and when I try to unlock again it says I cannot unlock it (although I did enable OEM unlock in the first place, that's how I flashed in the first place).
SO HERE's the bottom line:
I am stuck with OEM lock enable and ONLY fastboot (cannot load into recovery).
I thought I installing OTA (which I can install with OEM lock), but I need ADB for that which I don't have.
ANY IDEAS????
THANKS A LOT IN ADVANCE GUYS!
Hello,
I've got a replacement Nexus 5X from Google after my first was dead. I never tried to unlock then before today.
Today, I've tried to unlock it and use the "flash-all.sh" script for pushing the stock Oreo build from Google.
fastboot flashing unlock seems to work, after using it (and confirm), the bootloader print "state unlocked" in red on the screen.
But when I used the "flash-all.sh" scripts, it re-lock after flashing the first part (and reboot). I've finally flashing it by adding "fastboot flashing unlock" between each flashing command in script.
After that, I've tested "fastboot flashing unlock" after Oreo in installed : it's works, but the phone re-lock itself at the next boot, preventing any rooting or custom ROM usage.
On my first Nexus 5X, one unlock was enough.
Is there a way to definitively unlock my phone ?
Edit : it seems I've this problem "No RPMB" is printed after Secure boot state.

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
Hey there,
I just wanna know if i unlock my bootloader (only unlocking) can i still get OTA and install it without problems?
Thanks in advanced
Yes you can.
I unlocked my bootloader when I first got the device and received all OTA updates without problems. The only time you notice it is when rebooting: there will be a message that your device is unlocked.
But an unlocked bootloader means that some apps (such as Netflix) cannot be installed, and some banking apps won't work.
Which is why I re-locked mine.
What I would have liked though, is a warning that this would also wipe the device. I thought i'd get a confirmation dialog but the "fastboot oem lock" command just proceeds with the wipe, no "are you sure?" is given.
Week ago I flashed the android 14 dev, don't liked it and yesterday flashed A13 (TQ1A.230205.002) with Android Flash Tool. Today I saw that I can't add my credit card to the Google Pay. I checked in settings and found out that my bootloader unlocked but the button is unavailable.
What can I do?
If your phone was rooted, then do a factory reset. Download and install the Google Platform tools, or if adb and fastboot drivers are installed system-wide, that's fine.
Connect phone to PC in fastboot mode
Enter the first command "fastboot devices"
Then type, "fastboot flashing unlock"
Confirm on your device to lock the bootloader
That's it. If you want a detailed guide, here are the instructions on how to unlock/relock the bootloader on a Pixel phone.

Yes, of course! Unlocking and relocking will erase and factory reset your phone, I use Google One to take backups.
Alternatively, you can also use the Android flash tool, and it will automatically do it for you. You just have to follow the on-screen instructions, and it will ask for your confirmation to lock the bootloader, and you also get the option to wipe data (never tried unchecking the wipe data option).
Here is the video tutorial, if you need it.
EDIT: apologies for covering much of what has already been discussed by @wrkadung, got ninja'd a bit there...
I wouldn't risk locking the bootloader via platform-tools....so many instances from all the way back from the original Pixel has had countless members hard-brick their Pixel's relocking the bootloader.
The safest way to go about it is to use the Android Flash Tool to flash both slots and relock bootloader; most hard bricks happen when it's not flashed to both slots and/or the improper factory image is used...
But the OEM unlocking being greyed out is sometimes SOP after unlocking the bootloader. It's not really anything to be concerned about. If Wallet isn't working properly, it is doubtful it is simply having the unlocked bootloader; Wallet usually doesn't work when rooted than it is the fact of an unlocked bootloader. You should try Force Stop-ing and Clear Data Wallet first. Then even "uninstall updates" and/or revert to an older version before locking the bootloader. ESPECIALLY if you don't wish to wipe the device by relocking the bootloader...

Yes, definitely, a stock factory image is required. Most people directly lock the bootloader on a rooted phone using adb & fastboot commands, which results in bricking the phone.
On stock firmware, it is working perfectly. Right now I am working on a video tutorial for Pixel 7 and it worked fine without any issues, it was just bootloader unlocked device (not rooted).
