OEM Unlocked - X Style (Pure) Q&A, Help & Troubleshooting

After unlocking the bootloader a month ago or so and installing tpxmm , I noticed oem unlock under developer options was disabled.
Well I had to enable oem unlock to disable device protection to reinstall tpxmm.
Should this be set to disabled now after install?

Doesn't matter. That setting only affects whether you can use the "fastboot oem unlock" command. Since your bootloader is currently unlocked, that setting will have no affect.

Old thread, but still relevant.
Are we sure about this? If "OEM unlocking" is disabled, does Moto's bootloader not block flashing certain images? I have read about other devices not allowing modification with this setting disabled, including flashing back to stock. The solution was restoring a full backup of stock in TWRP, then booting stock and enabling OEM unlocking.
Can anybody confirm if this is the case with the MXPE?

That's the phone I have.
In Android OS, Developer Settings -> Allow OEM Unlocking is Off, but boot loader was previously unlocked and I have TWRP 3.0.0 installed. Rebooting to bootloader shows
Code:
Device is UNLOCKED. Status code: 3
Software status: Modified
I was able to upgrade to TWRP 3.0.2 using fastboot despite the Developer Settings- > Allow OEM Unlocking setting.
Re-locking the bootloader and restoring to stock as a bit of a process for another thread and if your bootloader shows "Device is LOCKED" then you will need to change the setting in Android before fastboot oem unlock will work. I've never had to change the setting since then, though, and every factory reset in android set it back to Off.

Thank you for the info. Have you tried flashing stock recovery with the setting off? If so, no issues?

Not in a log time, so I just tried just now and did the following.
Installed factory recovery
booted into factory recovery
wiped cache (I couldn't remember how to get the menu in the factory recovery, so that took a while =D)
booted into android
rebooted back to boot loader
flashed twrp
booted into recovery to verify twrp installed and is functional
Everything seems to be working.

You flashed stock recovery with the OEM unlocking option turned off, correct? That's what I was reading on a Hauwei device was the problem. With the setting turned off in stock, it wouldn't let him flash stock recovery image. He had to restore via twrp backup.

Yes, I left the OEM unlocking option in Developer Settings turned off through the whole process. I haven't turned that setting on since I originally unlocked my bootloader back in January.

Bootloop With locked bootloader 7.0

My 6p is stuck in a bootloop. nbd90x build my bootloader is locked is there anyway to unlock from adb. I have already tried sideloading ndb90x through adb wipping chache and user data and still no luck. Help me Xda youre my only hope..
So you previously enabled USB debugging, how about OEM unlocking? If so, use 'fastboot flashing unlock' to unlock the bootloader. Note that internal storage will be completely wiped. Everything. Though with USB debugging enabled, you should be able to adb pull the contents of you SD card first. If you can unlock the bootloader you can try flashing factory images with fastboot. Otherwise, not much else besides RMA it with Google. There's been a few reports of stock N6Ps bootlooping. Haven't seen anyone post that Google denied the claim.
no bootloader is locked so cant flash using flashboot but debugging is enabled so I am able to use adb .
I know. What I'm asking is if you enabled allow OEM unlocking in developer settings? That doesn't unlock your bootloader in itself. You still need to use fastboot to do it. However if that setting IS enabled what you can do is... Use ADB to pull your internal storage to PC. Then use fastboot to unlock the bootloader and flash factory images. If the setting is not enabled, and wiping data and flashing an OTA don't work, I'm not sure what else can be done.
You can try downloading the 7.1 dev preview OTA and seeing if it updates whatever is causing it to fail. Other than those, RMA would be your best bet.
https://developer.android.com/preview/download.html#device-preview
After sideloading a ton of times between 7.0 and 7.1, one time i got it to boot up then i immediately enabled oem unlock then it crashed again... so now I am able to flash through fastboot although I havent been able to get it to boot again. Is it normal for bootloops to not get fixed by flashing?
Hijacking your post to report what is happening to me. I posted the same thing on the Android Beta program community on G+.
Have been using the latest beta since it came out on completely stock 6P (locked bootloader, unrooted). Everything working normally when yesterday around 10 or 11AM, phone starts to bootloop OUT OF NOWHERE, it was just sitting there on the table while I was working. I could still get to bootloader/recovery, so that was a bit of a relief. First thing I tried: clear cache, nothing. Then proceed to wipe/factory reset the device, to no avail. Immediately downloaded the latest factory image from Google's page, tried flashing it but couldn't since the bootloader was locked (OEM unlock option also disabled). Then downloaded the beta OTA and sideloaded it, process went through OK but device still bootloops. Tried sideloading the latest stable OTA but didn't work since it was from a previous build. Ran out of ideas. So there I was creating a thread on XDA for help while the device was still on its bootloop rush, about to hit the Submit button when again OUT OF THE BLUE SKY the device decides to boot itself back up. First thing I did was unlock the bootloader. Phone worked normally for 6 or 7 hours, when I'm doing something on it and then again, screen froze and bootloop starts again. This time I only reset the device and left the it bootlooping, after about 30 minutes it boots up again. I unenrolled from the beta and installed the latest 7.0 build. Everything working fine for the last 12 hours. Anyone have any idea on what can cause the device to bootloop like that? Never seen anything like it.
Yea I signed up for the beta program too do you have the link to unenroll? So you just reset and let it sit?
Here you go

do you remember what you did to get it to boot?

Well, that's the thing. Everything I tried didn't seem to work. I couldn't flash the factory image since the bootloader was locked. I was able to sideload the beta OTA but the device still bootlooped after that. So I just left it bootlooping and after around 20 or 30 minutes the device booted normally. I have no idea what caused it and what I did to make it work again.
P.S: device restarted 2 times while I was typing this.

If your boot loader is locked you are screwed, sorry to say, I would RMA it. Unbelievable an update can mess a phone up...that's why I always unlock the bootloader first thing and never lock it. I need complete control of my phone.
Edit: Only thing I can think of is delete the partitions with fastboot or adb and reflash factory image.
boot loader is unlocked now Ive tried flashing using the flash-all script but the phone still wont boot

As a last resort, flash all of the images manually with fastboot. This will wipe all userdata and completely format the SDcard. Nothing will be left. Extract the bootloader and radio images from the factory images zip. Flash them in fastboot. Reboot to fastboot again. Extract the next zip in the same folder as BL & radio images and flash the vendor, system, boot, recovery & userdata image files. Just for good measure, boot to recovery (stock Android recovery) and perform a factory reset & cache wipe. If the phone still fails to boot, your only option would be to RMA it at this point.
Note: As per Heisenberg's sticky thread, do NOT flash userdata.img if you have anything besides the 32gb model as you will only have the ~32gb storage available. If you're using a model with more storage, just use fastboot to format userdata but don't flash the image.
Ill try that.. but isnt the warranty voided because the bootloader is unlocked?

Not on a Nexus, no.
Added: I had to RMA mine after the phone got its first update. I unlocked the bootloader and stayed stock for a long time (until N came out). I took the OTA in About Phone and it applied with no problems but the phone would not boot. Factory images also couldn't get it running. Stock recovery and all. RMA'd without issues. I didn't tell them, just sent it in. If they tried to boot it they would've seen the unlock symbol. There's also a thread somewhere buried in the general section where someone called Google and asked and they confirmed to them that unlocking does not void warranty. I'll try to find it for you.
Found it: http://forum.xda-developers.com/nexus-6p/general/unlocking-bootloader-warranty-google-t3229804/page1
I also returned 4 faulty Nexus 5's (mostly screen artifacts) all unlocked with no problems.

Phone is locked with factory(?) password after relocking bootloader, no recovery mode

Hi guys, I tried flashing stock rom and re-locking the bootloader so that I could have the phone completely stock. However, after re-locking the bootloader, I seem to have bricked the phone. I've scoured the forum for fixes, tried tenfar's tool, and nothing has worked yet. Hopefully someone has come across this situation before and can advise me on how to get my phone working again.
So how I got to this point.
-Originally the phone was on stock rom, rooted, with official TWRP recovery.
-Booted into TWRP, wiped cache, dalvik, data.
-Flashed ZTE_A2017U.B29_MergeBootStack_by_DrakenFX.zip.
-Flashed ZTE_A2017U.B29_StockSystem_by_DrakenFX.zip.
-Rebooted phone, went through initial setup, then turned on Allow OEM Unlocking in Dev Options.
-Rebooted back into TWRP, used Minimal ADB to fastboot oem lock.
So the phone rebooted twice from there, and seemed like it was going to boot properly, but the first screen that appeared was a lock screen asking for the password. I didn't set any passwords, and couldn't find any default factory passwords even looking through the zteusa forums on posts for similar situations. Then I tried rebooting into the bootloader to factory reset the phone, but trying to boot into the bootloader only leads to a black screen after the ZTE boot logo. That's where I'm currently stuck. No matter what I try, be it tenfar's tool, I can't get into anything but the black screen or the password-locked screen.
Using tenfar's tool, after I issue the axon7root.exe -p 3 command, it shows the next two lines, up to Version 1.10, then does nothing else. I'm not sure if this is because I flashed B29, and the tool only goes up to B27.
Any advice would be greatly appreciated!
Tennear's tool for flashing a boot and recovery image seems the most promising I think, but I don't quite understand how to use it.
-Rebooted back into TWRP, used Minimal ADB to fastboot oem lock.

First, you shouldn't (can't?) relock the bootloader while you're using a custom recovery. Additionally, I don't think you can issue fastboot commands to recovery.
Boot into TWRP and do a factory reset from there.
If not, flash the ZTE B29 image either via stock recovery (flashed via TWRP/tenfar's tool), or edit the install script to make it flashable via TWRP.

Nexus 6P: Default Bootloader Setting; Locked?

Sorry for the confusing title but I'm curious...
Being fairly new to Android in general and a total newbie regarding rooting these devices (a Nexus 6P in my case), I'm finding myself questioning some of the features and functions as they're related to rooting. In this instance, I'm wondering about "OEM unlocking" as it's listed in Developer Options. I've successfully flashed several factory OEM images that past few days as well as flashed TWRP, installed SuperSU, made backups of those images and all has worked out fine. From Marshmallow to Nougat 7.1.1 and to now what I've recently flashed, Android O, all the flashing of OEM software and using TWRP to recovery those backup factory images I'd made has worked, all's gone well without a hitch.
When I first activated Developer Options in settings when the phone was brand new, fresh out of the box, I noticed that "OEM unlocking" was in locked bootloader status. I'm guessing that's a factory default kernel or OS setting. Why is it that after unlocking the bootloader and flashing a complete factory zip image, when I go into Developer Options, the "OEM unlocking" is now displaying "Bootloader is already unlocked"? If it's a complete factory image that's been flashed, wouldn't "OEM unlocking" be locked by default because it's stock OEM software that's been installed? Guess I'm wondering if there are settings (like bootloader) that are not part of factory software images and reside in some hidden partition or in firmware or . . . .
By the way, the only reason I'm flashing all these different images via TWRP recovery or not, is to become familiar with rooting basics, command prompts, curiosity and 'cause it's fun, at least for now. Guess it'll really get interesting when I start messing with custom ROMs.

Hello...
Once you allow "OEM unlocking" in developer options, it allows you to unlock your bootloader. Which you certainly did by:
fastboot flashing unlock
In bootloader...
You can flash as much as you want, the bootloader will remain unlocked. I don't know what partition keeps a record of the command, but flashing​ a new image doesn't lock as you can see. As long as you don't relock using:
fastboot flashing lock
Don't do it if you are not full stock, because you can't flash anything if something goes wrong...
Cheers...
If it's one take away I've come away with so far after reading several posts here at XDA, ones that include tales of rooting gone bad, it's to NOT lock the bootloader unlesss the device is back to stock (thanks Heisenberg). Fortunately, I'd read that before moving to and from locked bootloader status'. Thanks for the reminder, too!

How to Stock FW and Relock Bootloader? OP5

Hi all,
I've wanted to go back to Stock OS but when i type "fastboot oem lock" it says "FAILED <remote: Flashing Lock is not allowed."
Everything boots normally to OS 4.5.2. In DEV options the Unlock Bootloader is greyed out and says bootloader is already unlocked.
What can i do?
Cheers
These instructions did work for me with the OnePlus 3/3T. They should also work for the OnePlus5, just make sure that you download the OnePlus5 version of the software and recovery.

Thanks I asked the same question earlier glad u tried it..I want to make sure we can relock it before I get the phone. Did u enable oem unlocking in the developer options before doing a fastboot oem lock? Also, make sure you are on stock everything including recovery..

Hello. I first thing I do always is to install drivers. I start by connecting the phone to the laptop in charge mode, then in transfer files mode, MTP or camera. In this way he will recognise all the drivers your laptop needs.
Also I enter in fastboot mode and recovery so the laptop can recognise the drivers and always reboot laptop and phone just to double check.
What I did was: go to Developer Options and enabled Unlock Bootloader and USB Debugging.
Then I accepted the laptop request on my phone and all drives were OK.
I run CMD and typed fastboot devices to see if it recognises my phone and it displayed a serial number. So I proceed next to type fastboot oem unlock and the process went OK and on my phone it asked Yes or No to unlock and I choose yes.
Then I flash a twrp image by typing on CMD: fastboot flash recovery recovery.img (my twrp I'm had other name so I rename it. You need to enable "Show file extensions" in Windows so you can see what the extension is).
I then type fastboot boot recovery.img and the phone entered in Recovery Mode in this case TWRP.
My phone was always connected to the laptop and he open the internal storage window so I drag the supersu inside.
Then on TWRP I wiped dalvik and cache and I went to Install and installed the SupeSU on my internal memory root.
The phone then rebooted and ready to go.
But then I went to developer options and the Unlock bootloader was greyed out. I unroot my phone and flashed a stock recovery for OP5 and the stock image 4.5.2 and when I type fastboot oem lock it always says it can't be flashed.
I need to stock it since I'm giving to a family member and they don't understand much about phones and If there's a problem the warranty doesn't cover.
Just installed supersu to try an app. I never install 3rd party roms.

if your phones boots its not bricked... My guess is that you data is corrupted, i would wipe everything including userdata en reflashing the stock with recovery.

Hi right before your comment i managed lol.
I re-flash the stock recovery and in recovery i reset and wipe everything. then i install the OS4.5.3 by ADB Sideload and it's working now.
Just wanted to get rid of the inital warning that my bootloader is unlocked. I want to lock again.
I rooted my device with Magisk, and now I want to restore it to factory state.
I flashed stock recovery and OOS several times, wiped everything but fastboot oem lock failed all times (FAILED (remote: Flashing Lock is not allowed)).
Can you help me?
What should I do to relock bootloader?

here in this video u can see in detail how to lock bootloader. hope this help you
https://www.youtube.com/watch?v=CQYCSdDUdAU
HOW TO RELOCK..
Install TWRP and Magisk if you don't have them yet.
Magisk should allow you to slide "OEM unlocking" to "enabled"
Reboot to fastboot
Flash stock recovery via fastboot.
Run locking via fastboot flashing lock
Allow it to reboot and upon start up it will say device corrupted (THIS IS NORMAL)
Boot to recovery via the warning start screen.
Once in recovery, sideload latest FW.
Profit.
I usually do it this way (successfully):
Wipe everything but OTG in TWRP
Format data
Reboot to TWRP
Flash the full stock OOS zip
Reboot to fastboot
Flash stock recovery
Lock bootloader with the fastboot lock command
Has anyone made any progress with this? I too am having the issue as described and have tried the solution by Ricyksydhu, along with solutions from various other places around the net.

Can you use fastboot (volume down+power)? If you don't have Android SDK, then install Minimal ADB and Fastboot, open cmd in that directory and type "fastboot device" (or "fastboot devices"?) while phone is connected via USB in fastboot mode. If it displays your phone's serial number, then you can use fastboot. If it doesn't show you anything, then I think wiping your phone in recovery or performing a clean flash through Mi Flash is the only way. However, if you can use fastboot, then the next step would be booting into TWRP... but we'll get to that once you confirm if it's working or not.

Hi,
i have checked by typing command---fastboot reboot and my phone reboots and hangs at android one screen so that means i can use fastboot but strangely didnt see in fastboot devices but i found output for fastboot oem device-info where device unlocked shows false and other status.
If this is enough for using fastboot to boot into TWRP?

Actually bad news is that to boot into TWRP you need to unlock your bootloader first (fastboot oem unlock), but to do that I think you need to have enabled "OEM unlocking" in developer settings (though strangely I am unlocked, but for me this option is disabled). Try unlocking anyway. If it doesn't work, then I would follow this guide to clean flash official firmware with Mi Flash Tool. Be warned, you will lose all your data if you manage to unlock your device.

Hi,
Is that mean i will still loose all data even if i unlock bootloader?
And i am unable to unlock bootloader by command. So only option i have now to do factoryreset/wipe data?
So after factory reset again i need to flash the ROM ? Because if again i need to flash ROM, i understand the prerequisite is Bootloader unlock which will create issue again.
Please suggest.

No, if you wipe your phone through recovery you won't need to flash anything. It just deletes all your stuff without touching the system.

I bit the bullet and ordered an EDL cable so we'll see if i get anywhere with that. I've read that newer Xiaomi devices wont work with EDL cable and only option is to use the test point method....not sure how accurate that is but guess i'll find out whenever the cable gets here.

You can try fastboot oem edl
To put the phone in EDL mode without specific cable
However why not wipe data from the recovery?
Just use fastboot reboot recovery

Thanks for the suggestions. I know when I ran fastboot oem edl previously I get message stating device already locked.
If i do fastboot reboot recovery i got an error ..i believe not allowed but will have to check later tonight.

If you see a triangle, you are in recovery mode
You need to press a button combination to see options, Search on Google for that
