[Q] OnePlus One - Unable to unlock bootloader again after relocking

Hi Guys,
Hope to get some help here.
So i unlocked the bootloader of my one plus one and installed supersu + Twrp recovery. All worked fine until i decided to relock the bootloader.
I've put the device into fastboot mode and executed "fastboot oem lock" with twrp recovery still in there.
Now i am trying to unlock the bootloader again using "fastboot oem unlock" to be able to flash the stock recovery and having issues.
output of commands:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock
...
OKAY [ 0.004s]
finished. total time: 0.005s
C:\Program Files (x86)\Minimal ADB and Fastboot>
After this it boots straight to twrp recovery. I then hit reboot system and go back to fastboot mode and run the below:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery recovery
.img
target reported max download size of 536870912 bytes
sending 'recovery' (12260 KB)...
OKAY [ 0.389s]
writing 'recovery'...
FAILED (remote: Device not unlocked cannot flash or erase)
finished. total time: 0.404s
Anyone has an idea how i can unlock the bootloader again ?
Thanks
Vik

Would it let you reflash the stock factory image thru fastboot? Maybe if you could do that it would let you unlock again. And it would give you stock recovery.
Or else what about the option in developer settings to update the stock cm recovery when installing an update. Maybe you could install an official update thru TWRP and get stock recovery back?
Just throwing out ideas, hope you figure it out

I've documented ths same issue describe here: http://forum.xda-developers.com/oneplus-one/help/locked-bootloader-twr-rooted-t2820341

Hi YrrchSebor,
Thanks for the reply.. I already tried all that, even using adb sideload and keep getting same error as mentioned above. I'll try the solution lemonspeakers suggested later today and post the outcome.

Be careful if you updated your phone to XNPH30O OTA,
!!! Warning !!!
In the NEW OTA CM11S XNPH30O, the bootloader (aboot) img size changed....
We request all not to apply the unlocker scripts on the new bootloader , until we confirm/find the new bit position.
It might brick your phone and corrupt bootloader...

It won't work.. do not try it if you updated to XNPH30O using the OTA.

I ran this command:
Code:

But the next step does not work:
Code:
It will boot your phone into recovery once from the recovery image
stored in your PC temporarily
then you can flash the zip either by sideload or from sdcard...
I got:
downloading 'boot.img'...
OKAY [ 0.484s]

FAILED (remote: Device not unlocked cannot boot)

That's because you can't boot a recovery with the recent bootloader unless you're unlocked.

[RECOVERY][TWRP][Unofficial][Port][ROOT] Ulefone T1

This is a ported TWRP that I put together from another MTK6757 recovery that was twrp ready. I have only used it so far to root my device. I am not responsible for any harm to your device.
1) Backup your phone.
2) Unlock Bootloader (!! YOU ARE WIPING EVERYTHING ON YOUR PHONE !!)
3) fastboot boot recovery-20170912-t1-twrp
4) Swipe modify system partition
5) Install desired root method (I installed Magisk here.)
6) You phone will be back to factory, with root installed.
Enjoy!

Succeeded
Thank you ^ ^
Open CMD (command prompt) and type the next command :
adb reboot bootloader (and press enter)
Now type the next command :
fastboot boot c:\adb\recovery.img (and press enter)
**I installed Magisk but magisk hide not wroking!!! **Why??

I only just got my T1 and this is my first time using it but under "Developer options" in settings of the device there is an option for "OEM unlocking". Googling that the first result says "OEM Unlock is a protective in Android Lollipop and later that is usually a step that users need to enable in order to officially unlock the bootloader of their device." Hopefully that helped.

Did this work for you and have you had any issues with your device at all? This is my first MTK device so I want to make sure it's all good. Seems almost too easy compared to rooting and unlocking my Xiaomi devices

When I enter the cmd fastboot reboot bootloader, all I get when the phone reboots is "bootloader mode...." in the lower left corner. When I type fastboot oem unlock all I get it "waiting for device"

The stock recovery comes up instead of flashed twrp

Hello,
When I try to reboot to recovery the stock recovery comes up instead of twrp.
I have flashed multiple versions (through adb) of compatible twrp recoveries, but the issue was the same with all of them.
I am on android oreo with the latest update.
I just want to access twrp.
Did anyone experienced the same, or does anyone know hot solve this problem?

How are you booting to TWRP?
Which command are you using to flash TWRP?
Unplug usb + power + vol up, release pwr when phone vibrates/huawei logo is seen.
Or use 'adb reboot recovery'

Hi
I have the same problem... Let me just round up the facts:
I have a Huawei Mate 9 Pro
The phone is unlocked, when i boot in to bootloader (adb reboot bootloader) it says PHONE Unlocked + FRP Unlock
When I flash twrp I get:
fastboot flash recovery_ramdisk twrp-3.1.1-0-hi3660.img
Sending 'recovery_ramdisk' (27944 KB) OKAY [ 0.658s]
Writing 'recovery_ramdisk' OKAY [ 0.268s]
Finished. Total time: 0.943s
When I afterwards try to boot into recovery (adb reboot recovery)
Error
Please update your system
Error
Func NO 11 (Recovery image)
Func NO 2 (Load failed)
I currently have build no LON-L29 8.0.0.323(C432LOG)
All I want to do is flash a newer image, can I do it with adb/fastboot directly?

i am using this recovery for my Mate 9 (L29) at https://forum.xda-developers.com/p10-plus/development/recovery-twrp-3-2-1-0-oreo-t3734993. Works fine. I suggest when you flash it via fastboot, please don't use command to reboot phone. Instead, just unplug phone and manually shut it off. Then, hold vol up + power buttons, it should load TWRP. I experienced that the reboot command loads eRecovery than TWRP.

Only reason it would do this is because you're flashing an image meant for Nougat.

My OnePlus 7 Pro is bricked.

My OnePlus 7 Pro keep booting into fastboot mode. Neither I can access recovery nor can start the phone. It's always comes back to recovery.
Please help me getting it done.
Bootloader is unlocked.

You haven't given enough info, tell us step by step how your "Bootloader is unlocked".
We would need to know if you did it properly, you probably need to go into the recovery and perform a "Full wipe". Unlocking the bootloader usually does that anyway.
The normal method is:
Enabled developer settings by pressing the version number in the about section 7 times and entering your pin
Copy the adb developer folder from the mounted OnePlus driver partition you usually get on your computer when attaching the phone, into a folder on your hard drive, and enable adb in developer settings.
In developer settings enable "OEM unlocking"
Reboot into fastboot mode
Open a command window (with admin privileges) in the folder you copied to your hard drive (In Windows, hold down shift and right click inside the folder, then click "Open Command Window..."
Run the command "fastboot oem unlock"
Accept the prompt shown on the phone
This will wipe the phone back to factory reset so ensure you have backed up your data, although you should be doing that before you even start.
Flash the appropriate TWRP recovery partition (which afaik isn't even available yet so I'm not sure why you would unlock the bootloader so soon to be honest
If you didn't perform those steps or performed them in the wrong order then you've done it wrong.
Performing a factory reset in the recovery partition may get it booting again but it's hard to know with the minimal information you've provided.
Although again, why are you unlocking the bootloader when there hasn't been a TWRP version released yet? You won't be able to flash anything, not even Magisk.

I've unlocked bootloader by command of OEM unlocking.
After than the unlock, I rebooted it's again And installed some Magisk file, which made it stuck at fastboot.
I can't access the Recovery nor can restart Phone.
All I can do is switched it off And get back into fastboot again after.

Yeah, you can't flash things with the default recovery (That's just made for flashing the default builds), that's most likely why. Magisk was made to be flashed with TWRP.
Did you use the test TWRP here? If so, then go to that thread for help.
If you can get into the OnePlus recovery you could maybe grab a build from here and flash the default rom back, then start again using the guide I showed you but, tbh, I would wait until a good TWRP build is established and Magisk is confirmed to be working.
That thread also looks like it has the default recovery image too so you can flash that back on the phone with :
fastboot flash recovery filename (Just put the recovery image into the same folder as your adb.exe and fastboot.exe
Then see if you can reboot into it and flash the stock rom back on from the same thread.

How can I get things done back, all I've is fastboot.
It's a New set, please help (

Reading that thread again, flashing recovery is not as simple as it used to be due to the A/B partition model used now, so you'll need to read the instructions shown for recovery. My guess is that you didn't read them properly and flashed the recovery to the wrong partition. If you have flashed that TWRP then you need to seek support in that thread.

This will sound stupid, but I had similar issues with the pixel and it was due to drivers and the port. Tried from a different machine and worked. Do you have the luxury to do so ?

Man, I've flashed like tons of Custom ROMs and Twrp from the same machine everytime.
I used to be a Xioami Redmi Note 5 pro user, And I've flashed almost every ROMs And root and everything, and same with my Redmi Note 3.
I don't think the machine have some fault some how.
It was Just like I had unlocked the bootloader And just after I flashed some Magisk ISO file which got flashed completely, And then all I'm stucked with the Fastboot, everything Stopped working, And everytime I'm dragged info fastboot.
And also as I said, can't flash Twrp.

Since you are familiar with custom rom,unlocked bootloader etc you should had known already that you must NOT flash any kind Magisk staff without having proper and functional twrp.
Even if it flashed successful that doesn't mean will work after reboot and normal restart.
That why you've brick your device.
And on the other hand with A/B partition things has changed dramatically evolving all custom made staff and how they works.
Oneplus device not work the same way as Xiaomi you've described.

Any post that describe exactly what changed? I havent flashed custom roms/kernels in close to two years due to OOS being satisfying enough. What I have done is fastboot into twrp and flash magisk(I believe). Will I still be able to do that with OP7 Pro?

That was a stupidity, all I forgot was the command.
Now I used the same command and then used oxygen os fastboot flashable all bat file, as suggested by a member.
And here's my phone back. )
Thanks

I recently unlocked bootloader to flash Magisk so I could have root access. I was getting the same error and found out that you must do the flashing in "download mode", not in fastboot or bootloader mode.

I recently unlocked bootloader on my HTC U11 to flash Magisk so I could have root access. I was getting the same error and found out that you must do the flashing in "download mode", not in fastboot or bootloader mode.

Download mode

hi, sorry for the late reply, my brother "borrowed" my phone for a couple weeks and he did a factory reset. I don't have my phone yet, hopefully I won't have to unlock the phone again or flash Magisk into the bootloader again either...
To unlock the bootloader, I followed this nice and detailed tutorial here:

.
Then I followed Magisk's official tutorial on how to flash it without a custom recovery... here

... just go to the "How to install Magisk with ADB and Fastboot (without custom recovery)" section and read it carefully, but instead of rebooting the phone into fastboot mode, I had to do it all in download mode.
I I did not install TWRP custom recovery, I manually patched the stock "boot.img" file with Magisk and then flashed the patched boot with this command with the ADB tool in Windows (phone in download mode):
fastboot flash boot patched_boot.img. I wanted to keep HTC's stock recovery.
Then I rebooted the phone into Android, and opened "Magisk" app in Android to make sure the root was working...
I didn't have internet connection in my phone (data connection or wifi), I did it all offline.
If you don't have the locked "boot.img" you must check the exact version of your installed Android OS and download the correct RUU file. Then you can extract the boot.img from it, patch it with Magisk, then flash it into the phone.
I did it in download mode as it was failing in fastboot mode. Make sure to enter download mode when you restart your phone, not fastboot mode. I'm not responsible if you brick your phone. My phone is the "Global" version from India (6GB RAM, 128GB internal storage).

Issue was resolved. My phone's bootloader was unlocked and and top of all it got pie update on unlocked bootloader with rooted phone and updated to android pie, then it started creating random issues like phone booting time was around 10 to 15 mins and i was getting above mentioned error. whenever i was booting to download mode my system was not detecting my phone but in fastboot mode it was detecting (kind of strange issue)... which turns out to be a cable issue. Once i changed my cable my phone was detected in download mode. So i re-locked the bootloader and then again flashed the firmware everything came to normal. Phone is up and working fine and thanks for help again.
