Trying to root my note 10+, i've enabled the oem unlock and tried to follow a guide to unlock the bootloader. but when i try to press and hold the vol up key nothing happens and bootloader wont unlock, tried to just flash twrp but get blocked by OEM lock. any help appreciated.
did you find a solution? First you need to unlock this option from developer options.

I will receive my galaxy nexus few hours later and plan to unlock my phone. Is there a way to hide the unlock logo after I unlock the bootloader or Can I unlock the bootloader, then root the phone and relock the bootloader after to clear the logo but still get the root access. If yes, then how to relock the bootloader?
fastboot oem lock will re-lock the bootloader
But will I still get the root access of my phone after I relock the bootloader and will the unlock logo disappear when boot up after I relock the bootloader?
p.s. It is retail version
why do you need it locked?
I don't like the unlock logo at bootup and the warranty detail only state that I will lost the warranty if I unlock the bootloader, so relock it in case I need warranty, it may cheat them
so then you relock it if you need to. Development for this phone is very young right now so you'll likely be doing alot of flashing. I flash different rom/kernel combinations probably 3-5 times a day with how often things are updating right now. Besides the little unlock symbol is pretty awesome
I know the development is young, that's why I post this. I just need to confirm
1) Is it possible to relock the bootloader in retail version
2) Will the unlock logo disappear after relock
3) Will the phone can still get the root access after relock the bootloader
Thx very much and please reply me if anyone know!!

1) Yes, "fastboot oem lock"
2) Yes
3) Yes, while "fastboot oem lock" does not touch any of your data, "fastboot oem unlock WILL delete all your data. None of these processes can remove root access, the only way to remove it is to reflash the system partition, either by flashing it manually or through an OTA update.

So lately, I tried to unlock bootloader of my Samsung Galaxy M30 with One UI Core 2.0. As I had read in many guides that after successful unlock, the option of unlocking OEM will be grayed out. But when I enabled it, it asked for my device PIN, then Samsung account password and switched off automatically. After factory reset, it booted up but the OEM unlock option was still blue and togglable. It read Bootloader already unlocked!
I'm confused because there was no 'device lock' mode in download mode, no need to 'long press power up to unlock Bootloader in download mode' or 'no gray toggles'.
On Download Mode I could see "OEM lock: OFF" . Does it mean that my Bootloader is unlock.

You are bootloader unlocked. Check the guides on this forum, and also the TWRP thread.

hello, urgent help me. I have a samsung M30 which I flash with an android 10 binary 6 rom. and after the tactility of my phone no longer works. I want to bring the system back to android 9, but I can't.
please give me any solution, waiting for your answer
When I boot the phone into fastboot mode, it doesn't recognize the bootloader is unlocked, even though once I turn on the phone, it does recognize it's already bootloader unlocked. I followed the EDL method tutorial, I have an LGG710EAW model, with the Indian versions of pie on it. Hope someone can help me figure out how to root it. Thanks.
I did a test rom on my Note 10+ N976N Exynos, I activated the OEM Unlock from the developers options, then I unlocked the boot loader from the download menu by long pressing the V+ key, then I want to go back to flash the stock rom but the OEM Unlock was grayed and in the download menu there is no v+ long press, I have only:
V up: Continue
V down: restart
Skey: show barcode
What should I do? or no hope and I will not be able to lock the BL?
Or can I update OTA with unlock bootloader?
Best Regards
Are you on a custom rom? If not :
1. enter fastboot mode
2. enter command like oem unlock but this time with oem lock or flash lock or just the opposite of unlock
DO NOT OTA UPDATE OVER UNLOCKED BOOTLOADER
Thank you for your help sir. But I risk to update my note10 plus on OTA with unlocked bootloader and I updated it successfully to latest version.
Hi I have the wifi only gt310 and when I go to developer options there is no OEM unlock feature. I can get to recovery though using power and vol up on boot. Im just wondering if I can proceed to flash a new rom or if I need to unlock the bootloader - as I have not been successful with finding those instructions on how to do this
I was able to use adb to see my device but fastboot bootloader restart did not work. It seemed to hang on waiting for device.
You don't need to unlock bootloader on wifi only versions
