Hi,
I have a Nexus 5, running stock Marshmallow MOB30B. Recently the power button stopped working,
The oem was initially unlocked, hence I tried re-flashing the phone to check if its a software issue, but not.
I locked the oem back once I re-flashed.
But now I'm not able to unlock the oem, as it requires a working Power Button to be pressed to confirm.
when i fire the below command from bootloader,
"fastboot oem unlock"
It asks a question in the device to confirm the action, there i am required to press the Power button to confirm (which I cannot do since the Power button is broken).
I tried almost all possible apps to root the device without unlocking oem, none of them works.
Towelroot is not supporting my device (even I cant do a temporary root and unlock oem through apps).
any other way to root the device requires unlocked bootloader.
I'm looking for something to do with adb shell or something to unlock the oem.
Please help me on this.
Thanks,
Harish G

Hi there,
I think i bought a fake Samsung Galaxy S6. But it works well, and it looks identical and has most of the futures of the real Galaxy s6.
As a fake Samsung phone, it doesn't have any Odin Download mode in it. So i tried to get into the bootloader via adb "adb reboot bootloader".
When i get there, i try to unlock the bootloader "fastboot oem unlock".
On the screen of the Phone i get a message about the fact im trying to unlock the bootloader etc. Press volume up to Unlock, Press Volume down to cancel.
The problem is, I can't press Volume Up for some reason, only Volume down. So i can't unlock the Bootloader to install custom recovery via ADB and finally install custom ROM.
Anyone any help? I can only access Stock recovery menu, some chinese test menu and the bootloader. Thats it.
Any help would be appreciated, i can provide any info you will possibly need.
grtz, Alex
Hi I'm hoping someone can help or at least point me in the right direction if i've missed a thread, i'm on Windows 7 64bit.
I appear to be stuck in a boot loop on my original Shield Tablet, stuck on nvidia screen when i try to go into recovery mode i get the "dead android" picture.
I have tried to unlock the bootloader and i get FAILED <remote: <>, device shows up under fastboot devices command, device shows up as Android Bootloader Interface in Device Manager.
I've searched the forums and seen this problem but everyone else seems to be able to unlock easily, this is the same but no replies https://forum.xda-developers.com/shield-tablet/help/nvidia-shield-unlock-bootloader-failed-t3178865.
Any help anyone can give me would be appreciated. Thanks in advance.
Check the recovery images section for your device here: https://developer.nvidia.com/shield-open-source
Instructions to unlock the bootloader:
Unlocking the Bootloader
Your SHIELD TABLET may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the "Volume Down" button to select "Unlock bootloader" option on device
- Press the "Power" button to confirm the unlock. Your device's bootloader is now unlocked.

You need to already have adb set up and the Shield connected to the PC to do this. If you don't have USB debugging enabled, this may not be possible, but you should still be able to get into recovery by booting the tablet with Vol- and power button (hold volume - and then just press the power button, don't hold both at the same time).
Yes I've tried that (I know the steps of unlocking the bootloader) that's when i get the FAILED error. When I try to enter recovery I get the "dead" Android picture.
Hello,
I have a Samsung galaxy S8, sm-g9500, I want to get it rooted, but I heard about the OEM unlock option in the developer options and I should Turn it on, but this option is not there.. And I am afraid to root my phone because the bootloader might be locked and I don't know how to unlock it. Is there anyway to know if it's locked or not?
Thanks in advance!
Yes you can..
You can put your device on download mode (hold power key and home key and volume down key together) then push volume up key.
Now you are in download mode, you can see something like : frp: on. OR frp: off.
If it is off then your mobile is not locked.
You can disable OEM by deleting your Google account from your device then your device will not request to enter your Google account and frp option will become : off.
Hi..
Im an LG g4 H5410 user....
My device seems not to have the oem unlock option in the developers section ...i searched for it but could not find it ....please would you help me find it since i want to install bootloader in my phone....thankz in advance
It tells you in download mode if its on or off, I had to re flash a firmware after messing about with my device and it didn't have OEM lock, checked in download mode and it was off so I flashed TWRP and I worked as expected.
My Galaxy S8 from T-mobile version SM-G950U don't show in any way the OEM. I tried many things. Does anyone knows how to Unlock it?
Hi,
is it a problem to relock the bootloader ?
What steps do i have to do ?

adb devices
Now, you will see a serial number in the command prompt window which indicates that the device is connected.
adb reboot bootloader
As the device booted into Fastboot mode, type the following command to lock the bootloader.
fastboot oem lock
Now, a confirmation pop-up will appear on the device screen. Use the volume buttons to navigate the highlight to “Relock Bootloader” and press the Power button to confirm it.
And after this, what will happen? Especially when you are rooted? Will it wipe all your data and can you start all over again, or will you face errors/issues/bootloops?
Person I wont just relock my bootloader. Your hash records are broken and you won't get working upgrades anymore, it's even the question if you still can oem unlock it again..... Besides this I don't know if, when you will brick your device, the msm tools still work. If you want to go back to stock better use MSMtools directly and go back to stock. https://www.xda-developers.com/how-to-unbrick-oneplus-nord-msmdownloadtool/amp/

Is this a safe method ? I dont want to brick the phone.... because i read a thread,where the relock ends in a bootloop..... THX
Im not test it but i have last week close BL on my O+ 8pro without any problem!
But before you close BL read this:
https://forum.xda-developers.com/on...de-fix-persist-img-loss-finger-print-t4125909
So i make it. And everything works without any problem.
If you have root remove it.
Flash last original firmware!
(so if you use patched boot.img you have now the "original" again!)
Then relock bootloader...
After that i test it with FP,Face Unlock and OTA update!
Everything is fine ...

This 10.5.11.AC01AA version is ok?
Wanting to root the device via magisk, I tried first to unlock the bootloader of my phone but apparently failed.
I started by activating the developer mode, set oem unlocking developer option in the settings then tried adb reboot bootloader : no success, the phone simply rebooted. A fastboot oem unlock just hung out waiting for a device.
I can go into download mode or recovery mode if that may help...
Any idea how to unlock this bootloader ? How can i check it is effectively unlocked ?
Thanks in advance for any help
It's well known that SAMSUNG mobiles don't have the Fastboot feature: there it's the Download mode.
FYI:
Power off your device. Press Volume Up + Volume Down and plug in your device to a PC to boot into download mode
When you enter download mode, Long press Volume Up button to unlock the bootloader.
ok well, let's forget about fastboot command then.
I'll answer myself on the original question, to unlock the bootloader:
switch off the phone
press volume up and volume down key
plugin a usb cable
choose "device unlock" with a long press volume up
after released the key up, choose "unlock" with volume up again
Now I'm looking to enter the download mode which I can't reach anymore. Any idea xXx yYy ?
Answer myself again
Apply the 3 first steps of my previous answer, you'll be in the same unlock screen as before but the first option will be "Continue". Choose it with volume up and you will end up in download mode !
Now I'll try rooting with magisk...
Rooting with magisk 25.2 done by a classical patching of AP from november release: AP_G736BXXU1BVK2_G736BXXU1BVK2_MQB58744363_REV00
It appears that this is the only thread on the entire forum for this phone?
Having just bought one for the removable battery and the dual SIM, I discovered that samsung in their infinite wisdom disabled the multiple users feature in their oneUI ROM, which really sucks because that was part of the reason I wanted the phone, to segregate certain apps into their own user account.
This all made me realize Root + custom ROM is probably the only way I will ever get that basic functionality returned.
So here I see that rooting is doable, but there appears to be zero results for un-samsung'd ROMs.
Which market is G736B? I was looking at ordering but I am in the US and the Samsung site is giving me the SM-G736UZKEXAA. Would the classical patching work on that?
The G736B model is sparsely distributed in EU, Asia, Africa and Oceania (see here). Your G736W US model is also based on Snapdragon 778G, it is probably the same phone with a few subtleties concerning 5G support (if any, can't find out) and software bloatware. I'd be surprised the above patching doesn't work but ... it's only a guess !
