How to Relock bootloader

Hello all.
I attempted to flash a ROM a while back and failed miserably. All I managed to do in the end was unlock the bootloader. I would like to change this, and set things back to they way they were; locked bootloader.
Is there anyway to achieve this? I would like to be able to use apps like Uber that won't work with an unlocked bootloader.
Any and all help is greatly appreciated.

Hello I think this could help you
https://youtu.be/8OywEYZ2cbw
This is a video about how to rebrand your mate 9
Now it in the steps it says that after you use the options 2 to rebrand it relock your bootloader, I don't know what mate you have but since you probably installed a custom recovery it is why you can't relock with the command, so my suggestion is this download the WHOTA update and also install the the software finder via Google Play. With it look for your specific model and copy the links to download the files for your specific model in your PC, Also do a Backup of your Oeminfo via the TWRP since it will be the only file you won't find, probably (if it happens to be the MHA-L09 C605 send it to me I need it for my phone I made the mistake of not backing up my Oeminfo).
If you download the files and follow the instructions of the video you will be able to relock your bootloader. But watch it 3 times and also download all the files and make sure to back up everything in your PC if something goes wrong.

Thanks guys. I've found a fairly simple solution.
This is the solution that worked for me.
1. Type "fastboot oem relock (your phone's unlock code)" and select unlock or yes with volume buttons & power.
Hopefully this method will help others.

Bootloader unlocked - then what?

Hi, so I have the Chinese PDEM30 version of the Oppo X2 Pro and I've applied for the bootloader unlock using the in depth testing APK from Oppo. As I believe it was made available in July, wondering if anyone else has done this yet and had approval already?
Once (if) I get approval, I gather the unlock is pretty simple:
1) App says approved
2) restart into recovery mode by holding power + volume down (after backing up data of course).
3) plug into PC and use ADB to unlock using the simple generic fasboot command (after enabling USB debugging in developer options of course).
PHONE UNLOCKED!
So here comes the silly question - does this mean I can load ANY ROM I want or does it have to be a custom ROM via TWRP or some other tool.
I simply want to load the global ROM, so assuming I can just do this from the recovery mode. Obviously right now it doesn't work as we get the "this is an older version" error. Will an unlocked bootloader solve this or is there more to it?
Appreciate any help from someone a bit more familiar with the process.
Thanks
Ben

and FYI, here's the current status in the testing app, I have to wait until the 10th September for the result. Fingers crossed!

can you share the apk ?

No, you have to register anyway as it's part of the criteria. Just register on Oppos UK site with your number, then login to the Chinese site using that login.

Root Sprint Oneplus 7 pro 5g GM1925

So I got this phone recently and I want to root it, but can't find any method with enough information and walk through.
It says "Your device is unlocked" under UICC Unlock. Also the OEM unlocking in the developer option is grayed out. So where do I go from here in order to unlock bootloader and then root? help please!

How to root Sprint Oneplus 7 pro 5g GM1925
Here are the steps that I found, from trial and error, to root Sprint Oneplus 7 pro 5g GM1925:
Disclaimer: I'm new to this. I did it on Windows 10. Maybe there is a simpler, shorter, and efficient way to do it, but I don't know it.
Some errors I did:
1. Unlocking the bootloader in Android 10. I could have done the procedure wrong, but when I tried unlocking the bootloader in Android 10 it didn't work. Yes, I could unlock it, but the phone wouldn't boot to "normal" and the recovery didn't work too; it just stood in a fastboot (if that is what is call) even when selecting start. Meaning I brick my device, but no worries I'm writing this because I manage a way to do it.
2. Updating the phone early in the steps to Android 10.
Steps:
1. Go to https://www.xda-developers.com/what-is-adb/ read and follow. You'll need this later. TIP Remember to select the "Default USB configuration" to "Transferring files" in developer options.
2. Power off your device. Connect the charging cable to the computer but NOT to the phone. On your computer right-click on the windows logo (the logo in the bottom left if you have the taskbar in the bottom). From there select "Device Manager". Hold both volume buttons (+ and -), and connect the charging cable to the phone. While holding the volume buttons, in Device Manager you should see that your phone is registered by a driver with a yellow exclamation mark. Update that driver. Disconnect the phone from the charging cable.
3. Go to https://forum.xda-developers.com/oneplus-7-pro/how-to/sprint-msmdownloadtool-unbrick-t3989841 and follow the steps. In summary, download the file provided and use it. This will format the phone. When it is done do a quick setup, the next step is going to format it again. This step will put the device in Android 9, but do NOT update. Remember to set up the phone for ADB.
4. Go to https://forum.xda-developers.com/on...otloader-unlock-sprint-oneplus-7-pro-t4042145 and follow the steps. In summary download, the file provided and use it. This step will unlock the bootloader. Do NOT update. After boot, remember to set up the phone for ADB. TIP The moment the application screen says is done (the download bar is green) rapidly hold both volume buttons (+ and -).
5. Finally, go to https://forum.xda-developers.com/oneplus-7-pro/how-to/guide-bootloader-unlock-twrp-install-t3940368 and follow the steps/links starting from the part of installing TWRP (the bootloader is already unlocked in step 4). In the link I provided, they'll be a link (the last one) that will let you update the phone, follow the steps layout there.
I hope this helps and works.

So basically what I learned is you have to flash a developer preview of 10. Unlock the bootloader then downgrade back to a stable international and then update and root. Fastboot commands where broken or not recognize in the dev preview so you had to switch up. But the dev prev allowed the oem unlock to be checked

I didn't understand some parts if not all of what you wrote, a bit lost with the terms like developer preview of 10, dev preview, and international (what does it mean in Android). I'm new to this. But what I can certainly affirm is, in an overview and in some way, I downgraded, did everything there: unlock the bootloader and root, and finally update.

Sorry to say, the answer is no. I have the Sprint model too, GM1925. No Dual SIM. (And now, thanks to Sprint AND T-Mobile, no 5G for us anymore EITHER! I'm pissed. But off topic...) See here, quote from Whoareyou, comment #18:
https://forum.xda-developers.com/oneplus-7-pro/help/5g-version-dual-sim-t3938677/page2/
This is incorrect, there is no way to enable dual SIM on the GM1920 or GM1925. This would require a modem.img with the SDX50 dsds configs, which we don't have.
you can however the flash the European 10 update on to the Sprint model, there are issues with Sprint data, but non Sprint carriers work fine.

Hello man. I know it has been a long time and I haven't responded to or help you, but here I am.
In Step 2 you are updating/installing the driver so the Phone can be recognized on your PC. What I can infer from this message is that you already have the driver; that means that you can continue to the next step. If that is not the case -you don't have the driver install- then selected one of the following two links to download the driver: Link #1 https://www.driverarchives.com/pc/hp/bm388aa-abm/231997/qualcomm-hs-usb-qdloader-9008-com4-.html Link #2 https://gsmusbdrivers.com/download/android-qualcomm-usb-driver/
I recommend Link #2. In both, you'll need a program that unzips the file -I recommend 7-zip (https://www.7-zip.org)-. Then run the executable file where you'll install the driver. And definitely after that, you can continue to the next step.
I hope this helps and works.

How To Guide [ROOT][GAPPS] Root and install GApps on stock Edge S/Chinese version

So you got the Edge S and want GApps? Basically you unlock your bootloader, root with Magisk, then install MagiskGApps.
DISCLAIMER: UNLOCKING YOUR BOOTLOADER MAY VOID YOUR WARRANTY, AND DOING ALL THESE THINGS IN THIS GUIDE MAY RESULT IN DAMAGE/BRICKING YOUR PHONE. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO YOUR PHONE. PROCEED AT YOUR OWN RISK.
1. Unlock the bootloader: that should be doable with their global bootloader unlock website here.
2. Download Lenovo Motoroa Smart Assistant (Rescue and Smart Assistant), and follow its instructions to "rescue" your device. It will lead you to boot into bootloader mode and download the firmware. Find the firmware file via the LMSA's downloads (should have a "show folder" button). You'll need the boot.img file for Magisk.
3. Download Magisk, then follow its instructions. You'll have to copy the boot.img to your device, then use Magisk to patch the boot file, then copy the modified one to your PC.
4. You'll need fastboot. If you don't have it already, you can download the Android SDK platform tools here. Then go into the folder, Shift+Right Click the folder, then "Open Command Prompt" or "Open PowerShell," you should have something close to one of those two. Copy your Magisk modified .img file to that folder, then you'll want to input:
fastboot flash boot [modified .img file]
Once that completes, you should see in large text, "Start" on your phone next to the power button. Press the power button, and it should boot, and you should have root now.
5. Download MagiskGApps to your phone, open Magisk on your phone, click the button that looks like a puzzle piece at the bottom of the screen, "Modules." Click "Install from storage," locate the MagiskGApps file, and install it. After that it will ask you to restart your phone, do that, then you'll just have to be patient as it takes time once its restarted to load everything. You also may need to update some or all of the apps, then you should be able to use the notification to finish setting up the phone with Google Setup.
Thanks to Motorola for making it easy to unlock their bootloaders
Thanks to the whole Magisk team for making an easy, awesome root (and more!)
Thanks to Wacko1805 (and team?) for making MagiskGApps. This is really awesome.

Magisk has a "Magisk Hide" which will allow it to pass SafetyNet, and most things which check on device security will think the device is secure. But unlocking BL and rooting does make the device less secure, and therefore incurs its own risks apart from bricking or damaging the device.

Google Pay works. But according to the Motorola website you should be able to relock the bootloader if yours doesn't work. But there's never any guarantee. If you need your device secure, recommend don't unlock bl or root, or wait to see if there's a root option without bootloader unlock that can be easily undone.

That's not good. Hopefully they can restore it back somehow. With this guide to unlock and flash gapps why would you need to flash G100 though? This seems to be itright now without one of rom developer's releases to get root & apps. For me this is all i would look for. Titanium backup on it and restore.. done until PE rom comes out.

I would think yes, if you flash different firmware, locking the BL would likely cause problems. It's very difficult to do anything w/o unlocked bootloader, except sometimes rooting is doable. That's pretty much the behavior I expect. If they come to this subforum, we might be able to help.

thank you. They did not ask for help. It seems that the lock BL is a self-verification switch, and then performs a verification system integrity.

I'm curious,If you unlock and flash other firmware and then flash back to the original firmware, can it be locked again?

Mine doesn't let me unlock its BL. I've got unlock code from moto and did a factory reset with SIM card in slot 1. After enabling developer mode and debugging the switch still is greyed out. So no chance to unlock it.
Has anyone got an idea what to try now?
Moto support answered yesterday to my request but also no solution since I told them that it doesn't work
Device is not branded. I got it from Amazon so no provider branding.
If this won't be able to be unlocked and rooted I'll have to return it and switch to a Google Pixel.

I had the same issue, you need to factory reset WITH your sim card in the phone, this will let you open the OEM unlock slide thing in the dev mode.
Then once its done you can fastboot and unlock the bootloader.

I did so, maybe I explained not so well. SIM was inserted and then I did factory reset by starting it from settings. After restart it's still the same - switch / unlock slider greyed out.

On my OG Pixel XL, I had to wait 7 days for the slider to become normal. By the time I got around to do it on the Edge S it was about the same time.... could be related

Now as you said that I remember that thingy with another device. Maybe a Xiaomi I think... With that I had to wait several days until the unlock code was delivered.
But there was a message, too, when trying to get it sooner, which said you needed to wait some more time.
Not sure if it's the the same for Moto devices? Then again, when thinking that you experienced the same with a Pixel, too...
Did anyone else make such an experience with his/her g100?

Make sure your on the latest OTA, Lenovo made a mistake on previous versions with the OEM Unlocking function not being enabled. They fixed it in latest ota.

RSA tool said the file I uploaded yesterday is the latest one available (and it's exactly the same as the installed version).
The device was released just a few days ago in Europe. Perhaps they fixed the unlock switch in other regions and still need to fix it in Europe..
Will wait until weekend if they come up with a solution. If not I'm afraid I have to return the device as I need it personally AND professionally, too - I'm field agent, so.... :/

Question I have a samsung galaxy A13 can anyone tell me how to begin rooting after developer mode is unlocked and USB debugging in activated never used debug?

I just wanna learn how to begin the rooting don't know what driver how to get a sdk what app nothing?

I'm looking at the A13 as well since the GS5 is now blocked by AT&T.

I just spoke to Samsung, and they told me the A13 G5 unlocked version purchased directly from them comes with an unlocked bootloader.

Samfirm should have the version of android you need for you're phone you need the Samsung flash tool su+twrp+magisk is optional good luck! Ps.always back up everything

I will be working on mine purchased from Metro PCS. Its OEM bootloader is locked at the moment. I will be using Magisk and flashing a TWRP. Utilizing an ADB wireless USB connection from PC. I will keep you posted if someone else doesnt beat me too it. Either way this thread is going so im sure together we can knock this out. Im going to do my LG Stylo 4 firsy. Its OEM came unlocked from Metro PCS...so i scored. Just havent had time. I just did my ZTE ZMax Pro Z981 from Metro PCS...it also was unlocked OEM. They will all need a PC usb connection and Magisck. You can find them in threads here. Good luck. Will post again when i get time. Hope this helps a little. Here you might not get an answer you want...but if you dig youll find what youre looking for...just got learn by doing...like they said...always backup... everything...first...dont forget to remove sd before you factory reset or you will wipe it. And your phone. If youre not sure...dont change things you dont know...you will brick your phone. Follow directions you find in threads...and you will be fine. I learned how to be a great chef from other chefs who told me the ingredients but never amounts of ingredients. Thats how you become a great chef and also become great developer...good luck guys. Im learning too. Share what you learn. FYI...the one click....dont bother...IJS...PC you will need for this....

How do you plan on flashing those if the bootloader is locked.....?

Sorry to break it to you, but it's a Samsung thing. It doesn't matter if it's a device from a carrier or carrier-free directly from Samsung, if you buy a U.S. Samsung phone you will not unlock bootloader freely.

Correct

first you need oem unlock on that takes pluging in phone holding volume+/- (both) and power till it shutdown and restarts with the unlock option in recovery

Just bought this but the 5G version

Hi, I just rooted my Samsung Galaxy A13. Here's a quick tutorial of what worked for me:
Prerequisites:
Install Heimdall onto your computer. I used Manjaro Linux as my OS, and haven't tested anything else. Install any drivers if necessary.
Install Magisk onto your phone. I recommend using the F-Droid store/app, or Magisk's GitHub page.
Steps
Install any updates for your phone.
Unlock Bootloader
First of all you need to unlock the bootloader:
Enable Developer Mode by navigating: Settings > About Phone > Software information.
Tap Build number about 7 or 8 times until it says You're now a developer.
Allowing the bootloader to be unlocked:
Settings > Developer Options > Enable OEM unlocking.
Allow it to be enabled if prompted.
Turn off your device.
Turn on Download Mode by holding down Volume Up and Volume Down.
When you see a blue screen, hold Volume Up until it shows Unlock Bootloader screen.
Press Volume Up to confirm.
Flashing firmware
https://samfw.com/ is a good resource for downloading firmware. Be careful that you're downloading the correct firmware though. You can find information by navigating on your phone:
Settings > About Phone, and Settings > About Phone > Software information. If you call *#1234# it will show you the current firmware.
Extract the archive.
Extract the file staring with AP.
Extract the file boot.img.IZ4.
Move boot.img onto your phone.
Open Magisk. Click install. Locate and patch the file. Move the file back onto your computers.
Extract the file starting with CSC. Locate the pit file.
Open Heimdall.
Choose the pit file and the patched boot image.
Put your phone in Download Mode and connect via USB.
Flash your phone.
If it worked successfully, your phone will reboot. It will probably throw an error before starting. Choose to do a factory reset. This will delete all the user data, but the patched boot file will stay in place.
Download Magisk again. Follow the prompts.
To test if you have super user access, install Termux from the F-Droid store. type su into the terminal. You will get a pop up asking if you want to give super user permissions.
Congratulations! You're now the UNIX sysadmin of your own phone!

hello Everyone, a friend of mine from America bought an A13 5G, now we are in Europe and the phone is blocked.
exactly inserting a European sim says:
Phone locked. Please contact our customer service center to unlock your phone.
i tried to unlocked bootloader, but unfortunately i don't have OEM unlock present, no way i get it out!
there is a complicated procedure with Flashing a Combination Firmware, but it looks difficult!!! I haven't done it yet.
but would it be possible to only unlock the phone to use European sims?
many thanks

Unlocking the bootloader would not do anything for you in regards to network unlocking. Those are 2 totally separate and distinct procedures.
What's the Baseband Version on the device? You can find that under Settings-->About-->Software Information (and don't do any software updates to the device if it prompts you to)

Hello, the first thing would be to unlock the bootloader which is very easy in Samsung terminals, In all Samsung is the same, you can see the following video that I recommend. No PC needed, The video is in Spanish but it is only to follow the same steps:
The second thing would be to get root, the easiest would be with Magisk, I recommend you watch this video since it is not necessary to format the cell phone, the video is also in Spanish, but you still follow the same steps. In this case, a PC is necessary:
Soon I will make a post myself, teaching you how to root without losing data, the same way as in the video, in case you didn't understand the video.

There is no boot.img.IZ4 im my ap file

ok i found the boot.img I extracted the ap file with winrar before. some how it does not see the .img files but untarring on linux worked. i managed to re flash the ap fille with odin and i saw lot of .img files being flashed and the extracted foldersize by winrar was way smaler than the archive. so that made me look at the ap file and i got the boot.img patched by magisk and made an lz4 file out of it how do i get that boot.img.lz4 back in the archive?
also whats wrong with fast boot?
"fastboot devices" lists my device when its connected but like many here post it does not work with other commands it failes like thIs :
fastboot flash bootloader b.img
Sending 'bootloader' (32768 KB) FAILED (remote: 'unknown command')
fastboot: error: Command failed
Tried other examples too but nothing works tried the fastboot included in android studio and one of the minimal adb/fastboot. the boot loader is unlocked (Not using fastboot) and odin works fine. my phone is in the "entertering fastboor mode" state .its a samsung galaxy a13 g5 and i flashed this firmware using odin
AP_A136BXXS2BWA1_A136BXXS2BWA1_MQB61124574_REV00_user_low_ship_MULTI_CERT_meta_OS13 now its stock again with no accounts.
fastboot reboot does work so some is right.
fastboot reboot
Rebooting OKAY [ 0.001s]
Finished. Total time: 0.005s
i hope some one can point me in the right direction.
thx

Fastboot isn't functional on Samsung devices. Samsung replaces it with Download mode. Therefore, all flashing is done via Download mode using Odin, not via fastboot mode using command terminal
