So OEM lock is enabled? AFAIK you need to OEM unlock first die being able to flash a custom rom. Best to check in your device's forum how to unlock.

Can you please help me unlock OEM on Yu Yuphoria 5010A with android OS.

Hi ,
I have recently purchased a Yu Yuphoria 5010A. I thought it had cyanogen mod but found to have just Android OS.
I have searched this forum for unlocking OEM and installing recovery to install cyanogen mod. I activated allow oem unlock in developers options and then tried to unlock via fastboot . fastboot detects the device but I am unable to unlock oem as it says "remote : oem unlock not allowed " . I was able to temporary boot into cwm recovery using "fastbbot 0x2A96 boot recovery.img" but it was not able to further install the mod.
Can you help with unlock the oem and install cyanogen mod. coz all the steps mentioned in this site and others have failed.
Thank you
Hii I also bought same model and also want cynogenmod os. But I don't know if its possible to flash cynogen os . but I rooted my phone an d its working perfectly. I had same problem of can't open bootloder not allowed to open bootloader. I checked the allow to open OEM in developer option. I guess this model has already unlocked bootloader cause I just rooted it even when it said can't unlock bootloader. You can try it but download stock ROM before if anything goes wrong. And please tell me if I can flash cynogen mod is it safe

What happens if I disable OEM-Unlock in developer settings?

I already unlocked the bootloader, happens anything if I turn off oem unlock in developer settings or will the bootloader relock?

Turned it off once by accident but turned on again.. Nothing changed
I don't think anything changes unless u relock it via fastboot, which at that point as long as u can boot back into the OS, u can always unlock it again, relocking bootloader will format ur data and u will no long be rooted or have twrp installed
locking your bootloader with root etc installed can cause major problems so before doing that you should flash a stock firmware otherwise you will be locked out
Why would you want to do this? There is no benefit to it if you plan to stay rooted.
Need to find something to do. You bored

I want to disable developer options, but if I do that OEM-Unlock automatically turns off and I don't want to reboot because I dont want that I lock myself out.

Just turning off Developer Options won't relock your bootloader. You can only do that manually in fastboot. But you'll also lose USB debugging, which means adb won't work anymore in case something goes wrong. (But leaving USB debugging on all the time isn't the best idea anyway.)
Hello everyone
I think I did that mistake
I have twrp installed on my phone Samsung SM-G532F . my phone was working just fine but I have locked the oem for no reason .
now when I turn off the device and tried to turn it on it shows { Custom binary blocked by FRP. (boot. img) }
and when I open recovery mode it shows { Custom binary blocked by FRP. (recovery. img) }
the download mode is working and shows that the FRP lock is on .
I tried to flash the stock recovery with odin but since the FRP is locked it failed .
the adb is not working because the device cannot boot , even the battery symbol when I plug my phone with a charger is not displayed and shows the error { Custom binary blocked by FRP. (boot. img) }
any ideas will help a lot .

You cannot boot with a custom recovery and a locked bootloader. As to how to fix this, you need to ask in the Samsung forums. This is for OnePlus 6.
If you have a oneplus look in the forum for msmdownloadtool and follow the steps, you can revive your phone.
If your phone its a samsung, search in samsung forums for a tool to unbrick your phone.

I downloaded and flashed the official firmware with odin and it worked . thanks for the reply
I did this once on my OnePlus X, disabled oem unlocking in developer options. phone and recovery worked fine. I did a backup. Flashed a new rom to test it. The rom had AOSP recovery in the zip, overwriting twrp (opx has separate recovery partition). I flashed gapps affter the rom and the setup wizard was crashing so I could not boot in the home screen. Tried TWRP, its gone. Tried to boot to twrp via fastboot, oem locked. Had to do hard brick reset. Backup and data, gone.
TLDR, you should leave it on, unless you are on stock firmware.
After flash a rom you must flash twrp recovery again, restart in recovery and flash gapps and magisk
First of all you have to flash combination file associated with your device model through ap slot of odin.
Then your phone will turn on and you can access settings through which you can turn on oem unlock.
Then you can install your desired rom into your device

I also accidentally turned off oem in rooted phone , Does my bootloader locked or I can safely reboot
I restored the stock firmware using Odin, but now I see that the bootloader is still unlocked.
When try to lock it again the system says: "If OEM unlock is turned off, your phone will be reset to factory default settings after restart. This will erase all of your data... " etc.
My question is: will the firmware be still in place? I don't mind everything being wiped, because most of it will be restored anyway when I login to Google and Samsung again.

Did you turn on OEM unlock?
Best method these days is to flash TWRP and then flash Magisk.

Yes i turned it on. u mean debug Mode usb?
Not USB debug, under develop options is a setting called 'OEM Unlocking'. You can't make modifications to your boot partition unless that's enabled, which means you can't root without it.

Black Shark CHINA (SKR-A0) - Unlock Bootloader

Hi everybody!
After the precious advice of user ndt192, I managed to unlock my SKR-A0 which, until this day, seemed un-unlockable.
THIS PROCEDURE WILL WIPE YOUR PHONE MEMORY SO REMEMBER TO BACKUP EVERYTHING
TL;DR
In developer options, OEM Unlocking must be ticked (if present), then I just issued a fastboot oem unlock while in fastboot mode.
I'm on the latest OTA (29-12-18, v. G66X1812291CN00MPX).
Full Tutorial
Enable developer options by tapping 7+ times on Settings -> About Phone -> Build Number
Enable USB Debugging and OEM Unlocking (if present) in Developer Options (Settings -> Other Settings -> Advanced Settings -> Developer Options)
Open a terminal and issue the command adb devices
On the phone, allow the access from your computer on the dialog that will be shown
In terminal adb reboot bootloader
Wait for the phone to reboot in bootloader mode
STOP AND THINK - DID YOU BACKUP EVERYTHING?
Issue the command fastboot oem unlock and wait for the OKAY in the terminal window
Reboot your phone with fastboot reboot
Now, you will be informed that because of the unlocking your phone memory is "corrupted" (aka not decryptable anymore) so the phone needs to be wiped. Agree and wait.
Hopefully, your bootloader will be unlocked now. You can check that by returning to fastboot mode and checking that the Status is Unlocked.
If you want TWRP/root, check out this thread.
This procedure didn't seem to work until a few months ago so I don't know exactly if this procedure works only on newest Joy UI versions or not. Try it out (at your own risk).
IMPORTANT - if you can't unlock with these steps, please post here with the version of Joy UI installed and the message shown after the fastboot oem unlock command

Question Removing the "Phone is locked can't be used without authorization"

Hey
Is there new 2023 methods to get rid of phone is locked screen? I enabled adb and removed kg lock. Upon disabling systemUI, the screen is blank, How can I manage to get rid of that lock by unistalling system app, or installing new systemUI and getting rid of the original one which is locked.

Install Odin on your camputeur and reinstall your whole system with it.
the A125F system firmware is at this link : https://samfw.com/firmware/SM-A125F
To get to re install the system is not that easy. First no option to factory reset at recovery mode, then locked bootloader. If you can assist on the same, it will really help
give it back jamal

If the bootloader is locked, then connect the phone at your pc and press volume + and volum - until the phone starting in download mod and there re install system with odin.

get into BROM Mode, use SP Flash Tool to flash normal firmware, then use FRP Bypass to bypass setup, then turn on OEM Unlocking, reboot to download, enable oem unlocking, reboot to download again, and flash TWRP, from TWRP flash a GSI or a custom ROM.

This may or may not work too, I have never tried this method before, but it looks fine for the removal of that screen. or in SAMFW Tool I think there is a MDM Bypass, if not then you can use SAMFW tool to bypass the FRP on that phone.
