locking the bootloader - Google Pixel 2 Questions & Answers

I just ordered the new Pixel 3 and it will be coming in the next few days, I'll be giving this Pixel 2 to my son and want to reset it and lock the bootloader back. I know how to reset the phone, but for locking the bootloader back do I just go into developer options and lock it there and that's it? I've never locked one back. Lol.

First, absolutely MAKE SURE you're 100% stock. Flash the complete factory image using the flash all batch file with the -w in it intact. This will wipe the device. Make sure it boots and there are no issues. Note, that after flashing the flash all batch file you'll need to set up the phone from scratch. You can bypass that process when you first boot. If it boots ok then you'll want to boot back into the bootloader and run the command
fastboot oem lock
This will wipe the device again.
If you are not 100% stock and you run into problems with a locked bootloader your device will be rendered pretty much useless.

Thank you for the info. I will go through these steps once I get the new phone.

[Q] Nexus 5 Soft-Bricked ! Please Help :( (Locked Bootloader, Stock Recovery)

Hello Guys,
I'm now in deep deep trouble as my Nexus 5 has got soft bricked and now stuck in a bootloop. Yesterday evening i unrooted my device, flashed everything to stock and locked the bootloader back because i was getting a really awful battery life upon rooting. Hence thought of reverting to stock. So flashed the stock image of 4.4.2 and setup my phone just like it came from a factory. Only thing i did this time was disable some Google Apps i.e Play News, Games & Magazines, Movies etc. Till midnight it was working too good with only a marginal battery drain on idle i.e 1% in 2 hrs or so.
Today morning when i woke up, i just entered the PIN code and unlocked the homescreen and then it just got stuck. I restarted my device and since then, its just stuck in a bootloop and whenever the phone tries to restart the OS, its gives numerous errors all related to Play sErvices and something like android.process.acore and Media.
I tried to factory reset by going through the stock recovery but even in that it gives the errors " Failed to mount /cache" and "Failed to mount /cache/recovery" with invalid arguments in the brackets.
Now i can't even flash stock as the Bootloader is in Locked State. I'm able to flash unlock Bootloader but when it asks to restart "fastboot reboot", it again gets stuck on the Google Play services error resulting again in locked state. That leaves me with a LOCKED BOOTLOADER, STOCK RECOVERY & NO USB DEBUGGING ENABLED.
What can i do now to get my device working people ? Feel like :crying: since its happened. Moreover, i can't RMA it as I'm now in a different country from where the phone wasn't purchased.

The tool specifically asks for Unlocked Bootloader and like i've already mentioned, its in a lock state. To unlock that, i need to have USB debugging enabled which i can't enable as i'm not able to even see the lockscreen, just stuck in a bootloop. :crying: I'm able to launch the Fastboot Mode and also partially unlock the bootloader but as soon as i type the command "fastboot reboot", the device again goes into bootloop starting the cycle again
Any more suggestions guys or should i assume my Nexus to be a paperweight ?

Go to the stock recovery and format cache.. Do it a couple of times till the /cache errors go away and then go to the bootloader and flash the stock factory images again. After flashing the stock images, don't boot it up, head over to the stock recovery and perform a factory reset and then reboot!

You can use command in fastboot "fastboot oem unlock" to unlock then reboot in fastboot again, and try this instruction (since you unlocked you should be able to do this).

(BTW you dont have to reboot after bl unlock.
fastboot oem unlock
then flash stock images iwhtout reboot)
What? USB Debugging doesn't have to be enabled. Bootloader unlocking is done from fastboot via 'fastboot oem unlock'.

Same is the case in Stock Recovery as well.
Can you please get me a solution on this. Would be highly obliged :good:

Successfully unlocked bootloader finally and installed TWRP. Booted in TWRP and performed Data Wipe and it failed. Again unable to mount /cache /persist /data etc commands showed. Then it tried formatting using make_ext4fs function but it failed. Swiped for a factory reset and it failed.
Used your ADB command afterwards and it displayed first daemon started successfully on port 5037 and then error in cmd : device not found.
What next ?
EDIT : Just noticed on the TWRP screen that my internal storage space is being shown as Zero (0) MB Now does this means my flash storage has died ? If that's the case and i need to RMA it, how to relock the bootloader , reset tamper flag and load stock recovery so that google doesn't cause any warranty issues. Please help me in that case as well.
EDIT 2 : Using fastboot, tried flash stock cache.img and userdata.img, it failed. When i flash system.img it went through perfectly. Also, got to know that the steps which you mentioned earlier, TWRP was booted temporarily and bootloader was unlocked temporarily. So does this means i don't need to relock or flash back something ? And, if i've unlocked and relocked the bootloader numerous times, how do i reset tamper flag ?

You could try one more thing. Format the /presist partition, For some reason it magically fixed other's devices, like for this guy and for an other in that same thread, but if you format it you will lose your wifi and bluetooth mac address, and some kind of DRM stuff. I made a tutorial how to fix wifi and bluetoot mac address problem after the formating, but I cant tell anything about the drm kind of files, because I still didnt get answers form the guys in that thread. That could mean they are experiencing no problems. Here is the zip which formats persist partition.

I tried all sort of things before finally giving up. Ultimately sent the device for RMA. Thanks for your inputs as well
@bitdomo, i have realised it was a case of dead memory chip only. I managed to relock the bootloader and reset the tamper flag (oem device info showed Tamper as "false") but now my only cause of concern is the LG Flash Tool. When i flashed the KOT9H firmware, it changed the original device version as mine came with 4.4 OOTB instead of 4.4.2. Can Google refuse the RMA citing this now ? Rest all, the kernel, recovery, bootloader, tamper flag is all stock. I coudn't even change that back to the original device version as i couldn't transfer any zip to the internal storage as it was dead.

Google can't get your actual device factory version, because it is only visible with lg flashtool, and that tool is an internal lg software. Google has nothing to with that tool.
By the way this lgfalsh tool makes your phone offical, because this is the offical tool used in LG service centres!!!!
Can you imagine a guy at google who takes your phone flashes a custom recovery, reads back the misc partition and search for the factory device version in the hex code. Then he checks your phone serial number and sees 310K then denies your rma request because your device factory version cant be that because in oktober 2013 there were no 4.4.2? I think no.
But if it bothers you then, you can flash krt16m, or if your nexus 5 had to do big update ~150 mb ota update then flash kfs78n if your device is D821 or flash kqs81m if your device is D820. Converted roms work too without problems I have tested them.

I have already sent the defective one for RMA so there's no question of flashing any files now. Google sends the new replacement device and and lieu of that they block temporarily the device's price for a period of 14-21 days in which the service centre ppl check for the issues what got the device in. And i think LG only is handling that as it made the device ? So my question still remains now can the LG guys intimate Google that the phone was flashed. ? But on the positive, the flash tool was of LG and it can't be turned unofficial What say ? I don't wish to pay again for a new device. If the service centre guys gives a thumbs up that phone indeed died as a result of hardware failure like emmc chip, then the card block is removed.
BTW, i am not aware whether Google itself handles the service or asks LG to do the same! Any inputs ?

I'm really afraid there's nothing you can do. Before relocking the bootloader, you must go back to an approved stock firmware. (See, when you rooted it, you changed it.)

If you have downloaded the full image from Google servers, try if you can fastboot using the boot image from the full image. It that boots your phone, you could try enabling unlock, get into fastboot to unlock for flashing. You can then flash the full image from unlocked fastboot

You can use the fastboot continue command.
This will boot up your phone normally and then you will be able to go to developer settings and enable oem unlocking again.
After this you will be able to unlock from fastboot again.

[Q] Bricked already? Stuck in bootloader

EDIT
Turns out I was two versions of adb/fastboot behind instead of one. Ignore me!
Hey all,
Yesterday I went to flash the factory image on my Pixel 2 that was running unlocked and rooted with Magisk and Snoke kernel, but it failed while trying to erase the cache partition. I found out that I wasn't using the latest fastboot because the Pixel doesn't use a cache partition so I updated and tried again, and the flash-all script seemed to work fine. But when it finished an rebooted the phone, I was back at the bootloader. I tried the start, recovery, and download mode buttons but they all sent me back to the bootloader. If I turn the phone off and plug it into a charger, the charging icon will come up on the screen for a second and then send me to the bootloader.
I tried flashing the files manually, but the process was hit or miss and would either hang forever or return a generic error (either a generic load error or check device console).
I can't boot the alpha TWRP because it returns a generic load/authentication error and quits.
At this point the flash-all will go through the motions and seem to work every time now, but when it reboots I'm back at square one. I can lock and unlock the bootloader and confirm it on the phone screen, I can flash the bootloader, boot, and system images, I can erase those images, I seem to be able to do everything I can usually do in there, but it's almost like my computer says it's working, but the phone isn't actually doing anything. Short of an RMA I'm not entirely sure what to do. Does anyone have any insight?

I set the active slot to b and rebooted and I got the warning message that the bootloader was unlocked and to continue, which brought me to the boot logo for a little bit, and then back to the bootloader.

# updated
https://forum.xda-developers.com/pixel-2/help/fastboot-update-resulted-bricked-device-t3694761
as this thread, just flash every img manually resolved this issue.

Can i just go back to how it was?

I don't even know why I wanted to root my phone. I'm like 3/4 of the way through rooting it and after I flash the boot_stock.img and the twrp installer .zip, I get this message saying
"Unmodified System Patition
Keep System Read only?
..."
and I don't know what to do. I'm following the video tutorial titled "OnePlus 7 Pro - How to Unlock the Bootloader, Install TWRP, and Root with Magisk" by the XDA devs and I get right up before I need to install Magisk or whatever. I don't care anymore.
Have I bricked my phone? Is there any way for me to go back?
Thanks for the advice.
That's just TWRP telling you the system partition isn't rooted, you can say no to allow read/write, then flash the TWRP zip. It sounds like you didn't do the original setup correctly, in the TWRP it tells you to use :
fastboot boot TWRP.img (replace for the current version)
Then the phone would boot into TWRP but TWRP isn't actually installed, that's why you should then flash the TWRP.zip and then immediately flash the latest Magisk to allow root and allow TWRP to remain in place.
Or, as you say, you could just lock the bootloader back but that will wipe data just as unlocking it did. That's a security measure to stop a malicious attempt to access files.
You could also, most likely, just download the zip for your rom version, put it in the root folder and perform a local "upgrade" which should just put your phone back to default, although, if you unlocked the bootloader it will still be unlocked, you need to run the following command to lock it again :
fastboot oem lock

You cared enough at one point to start the process. Whether to root or not is a personal decision, based on what types of added modifications of features you want out of root, and how important those are to you. Maybe you have changed your mind to that point. And I am biased to my own opinions. But that opinion would be to go ahead and finish the job, since you got this far. Nothing wrong is going on really, you just got stuck, not knowing what to do next. It does happen from time to time, when modding these devices. And nothing to get discouraged about. You did the right thing coming onto the forum and asking before doing something you were unsure about.

This is pretty hard to brick. Unlocking the bootloader, flashing TWRP, and root likely will not result in a real brick. Even if you brick the phone, there is an unbrick tool that will mostly likely get it up and running again.

I'm like 3/4 of the way through rooting it and after I flash the boot_stock.img

It's not necessary any longer to flash the patched boot.img in order to root. Follow the "Recommended" install method from the TWRP thread, which is simple and straightforward. It's pretty much what the previous response outlined above.

The method you are following (flashing a patched boot.img) does work. But it has more steps. And you have to be careful to flash the correct boot.img for your OOS version. Otherwise, you may have some issues. So going with the easier method is better, in my opinion.

Is that true for all phones?
If you have the Global OP7Pro and not the T-mobile variant you don't have to be afraid of bricking the phone. The MSM unbrick tool can bring your device back to stock if its bricked or even if its not. I am not sure if the MSM tool works on the T-mobile variants, but it might.
I've hard bricked this device and successfully used the tool to recover it.

That's just TWRP telling you the system partition isn't rooted, you can say no to allow read/write, then flash the TWRP zip. It sounds like you didn't do the original setup correctly, in the TWRP it tells you to use :
fastboot boot TWRP.img (replace for the current version)
Then the phone would boot into TWRP but TWRP isn't actually installed, that's why you should then flash the TWRP.zip and then immediately flash the latest Magisk to allow root and allow TWRP to remain in place.
Or, as you say, you could just lock the bootloader back but that will wipe data just as unlocking it did. That's a security measure to stop a malicious attempt to access files.
You could also, most likely, just download the zip for your rom version, put it in the root folder and perform a local "upgrade" which should just put your phone back to default, although, if you unlocked the bootloader it will still be unlocked, you need to run the following command to lock it again :
fastboot oem lock

Thanks for the advice. However, once flash the TWRP .zip installer, immediately flash magisk, and then attempt to reboot back into the system it just throws me back into TWRP saying "Unmodified System Partition". Is there something I should be doing after I flash Magisk?

Ignore this entire reply, I got it rooted. After flashing the TWRP installer, I rebooted back into recovery and flashed Magisk. Then, it booted and all is well, except for the fact that my bootloader is still unlocked and I still get that annoying splash screen telling me my data is insecure. How/should I relock my bootloader?
Well if you relock your bootloader you won't be rooted or have TWRP... It will also wipe all of your data like starting over when you got the phone out of the box.... If you want to stay rooted and use twrp you will have to deal with the splash screen all of us see it on our phones also. Basically you need to have the bootloader unlocked to keep root and have TWRP

You can't relock your bootloader, you currently do not have the default recovery partition, if you really want to relock your bootloader you would need to flash the stock rom back over itself so it replaces the recovery with the default one. Then you can run "fastboot oem lock" but be aware, as I said before, this will want to wipe your data so the rom will go back to default setup. Remember to disable bootloader unlocking from the developer settings if you do, then you will be back to the default stock rom state.

If you want root, you need to leave the bootloader unlocked. That is normal, and just how it is. The warning screen is just something to live with.
You need to return to full stock (ROM, boot.img, recovery) in order to relock the bootloader (otherwise you will get a bootloop or no boot). Which of course defeats the purpose of rooting the phone. So again, having the bootloader unlocked is the normal and expected state, when you are rooted.

Question Complete crash/shut down

My husband's phone deviced to completely shut down. When he tries to use the bootloader, it shows a message about being corrupt and not trusted. Any idea how to fix this?
-Selecting Bootloader, Recovery, Restart and Off all take him back to the same screen about corrupted phone.
Phone will go into FASTBOOT but will not go into RECOVERY mode.

This is what a half unlocked bootloader looks like. What device and build?

OnePlus 9 for TMobile.
If he's rooted, that means he didn't unlock the bootloader first. This is what causes that and I've done it myself.
I don't know if either of these will work but worth a shot in this order.
Option 1: *FLASH* UNMODIFIED stock boot.img via fastboot flash boot.img (whatever your filename is, or just drag and drop it in the adb cmd window)
2: Use the TMobile MSM tool to revert back to stock. I believe I tried this on the 6t and it didn't fix the issue somehow but in theory it should cause this is how OnePlus's legendary horrid tech support does it.
