Question Pixel 6 - Downgrade 13-12 - bootloader - Google Pixel 6

Afternoon folks.
I had upgraded to the 13 Beta, and was going to downgrade back to 12, the device rebooted and was left at the bootloader.
I had NOT OEM unlocked the device, so is there anyway I can unlock it from recovery, or rescue mode, just so I can flash the factory 12 image again.
or is there a way to install a factory image without the Unlock
Pixel 6
Regards

Stuck on cyanogenmod Recovery with bootloader locked (oem locked)

Hello guys. I unlocked the bootloader via adb (fastboot oem unlock) and flashed the cyanogenmod Recovery and after that i flashed Cyanogemod 13 (the official nightly).
Then I relocked the bootloader (fastboot oem lock)
Until here everything is fine. The problem is: After that I use my phone with CM13 normally, but I wanted to go back to stock, so I turn on developer options then i turned on the OEM unlocking thing, and usb debuging. And when i entered in fastboot mode to unlock the bootloader again i wrote via adb fastboot oem unlock the phone rebbot and now i am stucked on cyanogenmode recovery with the bootloader locked.
Another thing: if i flash the cyanogen 13 again the phone will allways reboot to recovery.

Never lock bootloader unless you are on stock ROM (oos). Now you need to unlock bootloader.For that you need stock ROM and stock recovery. Are you able to boot to any ROM,cm 13?
@ateresabelo maybe you have to flash stock Rom. Hopefully then it will allow you to unlock bootloader. Best of luck mate.

Thanks for the reply.
I can flash CM 13 ROM with cyanogenmod Recovery, but when the flash finish, when I reboot, the phone boot into recovery mode, and not boot into the ROM. So it flash the ROM without errors but boot into the Recovery again.

Flash stock ROM. Download it from oneplus website. And use TWRP recovery instead. Cwm is kind of obsolete and i m not sure if it works perfectly.

I cant do that. Because when I try to flash TWRP I recive the message that the bootloader is locked.

The thing is the recovery that i have is not CWM is the cyanogenmod Recovery (with oem locked). I only can boot into CM 13 ROM if i go to the fastboot mode and then type: fastboot continue. If I do that I can use the phone with CM 13.
But when I reboot my phone from the ROM it come back to the cyanogen Recovery and not boot to the CM 13 ROM. And I have to repeat the process: Go to fastboot and type fastboot continue in order to boot on my ROM.
So is any way to unlock the bootloader, like fastboot oem unlock (with the cyanogenmod Recovery instaled) in order to flash the OPX stock recovery or the TWRP recovery?

Ok, do one thing. Download flashify app and flash stock oxygen recovery through it. Remember this is an app. After that when you go to recovery, you should have stock oxygen recover. Flash oxygen os after that from stock recover. Try and let me know.

Just another question: for that task (flash the OPX stock recovery do I need root access?) I am asking this because I do not have the SUperSu installed. So maybe I need to use the cyanogenmod Recovery to flash the SuperSU and hope it works and then use flashify, right?

Thanks a lot. So, I am ready to do that. I have the stock Recovery for the OPX from OnePlus website and now I am ready to flash it via Flashify.
Just the last question, If I flash the stock recovery with the bootloader locked, does it will hardbrick or softbrick my phone? I just ask that, not because I dont trust you, because I trust, but because I read that is not a good ideia flash recoverys or roms with the bootloader locked.
Thanks again in advance, mate.

It worked, mate! Thanks a lot. Now I have the Stock OPX Recovery and the OxygenOS. Amazing! SO I can assume that I can now securly unlock the bootloader, flash TWRP and NEVER relock the bootloader again, right? (Unless if I have the stock Recovery and the stock ROM.)
Thanks a lot, again!!!

Just look at ROM section and decide, Its raining ROMs for oneplus x. ROMs( like zephyr, orion, ownROM etc) compiled with UBER toolchain are smoother, so you may wanna try them to get awed.

[HELP][CRITICAL] stuck with no recovery, no root and locked bootloader on Sultan CM13

Hello Guys,
I was trying to install OxygenOS 3.1.0 when I was on Sultanxda's CM13 but instead bricked the device.
What I did:-
1. Rebooted to TWRP and flashed stock OOS recovery and then clicked reboot into recovery.
2. Instead of rebooting in recovery my phone got stuck at the OnePlus logo.
3. I booted into fastboot to flash twrp.img but it says 'writing 'recovery'...
FAILED (remote: device is locked. Cannot erase)'
4. I repeated the same with stock recovery but no success and was not even able to boot to CM13 now.
Hence I was stuck on the OnePlus logo without any booting ROM or recovery and a locked bootloader (according to fastboot)
What I have already tried but failed:-
1. Tried to root with kingroot etc. (Before bricking)
2. Tried to unlock bootloader but failed because it has no recovery.
3. Tried to flash stock OOS 2.1.3-x
4. For now I used fastboot continue to boot back into CM13
Please help, I'm now stuck with cm13 without root and without any recovery installed.
P.S. I'm not even sure that if I clicked reboot then the phone will boot.
Thanks.
Okay, calm down.
Go to developer options and see if "OEM Unlocking" is enabled. If not, enable it.
Cool. Now enable USB Debugging, connect the phone to PC, open CMD and type
Code:
adb reboot bootloader
then
Code:
fastboot oem unlock
Download TWRP from the official website, rename it to recovery.img and then
Code:
fastboot flash recovery recovery.img
Now you have a recovery and an unlocked bootloader. Profit?
I hope this helps.

But if you read my post then you'll understand that due to absence of a recovery I can't unlock the bootloader and hence cannot flash twrp

Nexus 5x stuck in bootloop without usb debugging (stockrom NBD90W)

Hi there,
I would really appreciate any help at all. My device is stuck in bootloop but its adb and fastboot work properly. USB debugging is off and bootloader is locked.
What I have already tried:
1 - to flash any rom through fastboot: impossible, bootloader is locked
2 - to adb sideload an older rom OTA: no rom will be accepted, since NBD90W is the last one and you can't downgrade this way
3 - to adb sideload current rom OTA: works just fine, only thing I could do so far, but the phone remains in bootloop
4 - install a custom recovery through fastboot image.img: impossible, bootloader is locked

You're better off looking in the device-specific forum.
http://forum.xda-developers.com/nexus-5x
Unfortunately, I don't see a way to fix your problem that doesn't involve erasing your user data. You may have better luck in the subforum.
I don't care about my data. I'm giving up this phone after the last thing I've tried: I have successfully installed marshmallow (finally) through LGUP, and after I reboot it... stuck in bootloop! I don't know what this device problem is, but believe its a tiny hardware problem that will allow it to flash roms through various methods, while keep it stuck in bootloop. Does this make any sense at all?
Unlock the bootloader and flash a factory image.
Do a factory reset then flash latest stock rom

Bootloop even after flashing fastboot

Hi,
I bought yesterday the snapdragon global version and after installing many apps i rebooted the device and i got a bootloop. I didn't made any update, it came with global stable 8.1.10.0.
I can't enter recovery, only fastboot and i flashed sucessfuly 8.1.10.0 and 8.1.15.0 and none worked, i still got an endless bootloop with the MI logo then a white progress bar. When i try to enter recovery i get a phone logo and it says: pcsuite.mi.com.
What can i do in this situation?

Just to add more info, like i said i didn't made any update, just installed around 20 apps. I used an app called Activity Launcher on which i disabled some apps like gmail, calculator, google play music, movies. I am not sure if this has something to do with the bootloops.
Thanks in advance.
You cannot flash the fastboot ROM without unlocking the bootloader..
Just apply for unlocking the bootloader...
When approved unlock the bootloader then flash the fastboot ROM...
But getting the permission and unlocking the bootloader is gonna be very painful....

Can i unlock the bootloader with the phone like this? I can only enter fastboot mode.
Is this a normal behaviour? to get a bootloop without doing any update?

Yes you can unlock...
Although it's not normal to get bootloop without doing any update...
If possible then apply for replacing your phone with a new one...

Question Relock Bootloader

Hi,
has anybody tried to relock the bootloader?!
i was a little over hasty and unlocked a device. I thought (yeah, i didnt checked it ...) if asus is offering a unlocker, it should be no big deal to lock it again.
But everything i found is for the ZF8, and all i found does not work on the ZF9.
It starts that there is no adb/sideload option in recovery nor have i found a custom recovery.
And every relock command in fastboot is not known by the fastboot environement of the ZF9...
So has anybody found a way?
thx in advance.
Matt
Has anyone found a method to close the bootloader again? I'm thinking of opening it but I'm worried that I won't find a method to close it if necessary.

If you haven't tried it, you can try it with:
-fastboot oem asus-back
-fastboot oem asus-csc_lk
-fastboot flashing lock
-fastboot flashing lock_critical
-fastboot oem lock
-fastboot oem lock_critical
-fastboot flash !frp-partition! default_key.bin
-fastboot oem asus-lock
No. Didnt work. 'Command not supported in default implemantation' All of these commands.
I did not try the *critical commands and the "frp partition". I had not time to read me in on that. And i dont want to brick the phone complete.
For what it's worth, fastboot oem asus-csc_lk worked for me. It also wiped the phone itself, I didn't have to do it manually.

Same, though I expected that since I rooted.
For any one wondering how to update, just take the firmware file from ASUS's site, place it in your phone's internal storage, then either wait a few seconds for the update notification to pop up or restart your phone (you should see it then). Follow the prompts from there.

1. You can only re-lock the bootloader by going back to the stock firmware/recovery, losing twrp and magisk.
2. Re-locking the bootloader does not re-enable the OTA updates, but might help with Google Pay/SafetyNet attestation if that's broken for some reason.
3. This command works. Just flash the stock firmware and recovery, then do adb reboot bootloader and fastboot oem asus-csc_lk.

ok, just one last question. If I have the latest version (2060.113) with TWRP, to leave everything stock what I have to flash is the zip downloaded from ASUS (also 2060.113: https://dlcdnets.asus.com/pub/ASUS/ZenFone/AI2202/ASUS_AI2202-33.0804.2060.113-kernel-src.tar.gz?model=Zenfone%209 ). I have seen that there are other ROMs called RAW, but I don't know exactly which one to install. I'm afraid that when installing the zip from that link something "non-stock" will remain installed and when closing the bootloader the smartphone won't boot.

I can't say much about this. I don't think it's going to be a problem, but of course you're doing it at your own risk.
