OEM unlocked (showing in System) - Download mode -> OEM locked - Samsung Galaxy Note 10+ Questions & Answers

Hi,
I just got a second hand Galaxy Note 10+
And I'm trying to get TWRP up and running on that phone.
I'm havin huge issues with the OEM lock.
I already did a complete reset of the phone with a Sammobile firmware. Flashed it via ODIN. Everything was factory resetted.
Then I did the OEM unlock in the developer options. Rebooted. And it is showing that OEM is unlocked.
Then I tried to flash the TWRP-recovery via ODIN. But it always fails with the same message "Cutom binary(RECOVERY) by OEM lock"
I am no beginner. I already flashed many Samsung phones and have them all unlocked. Please help me with that issue.

OK, I got it working.
I just forgot to reboot directly into Download-mode. I always booted into the original recovery menu and there I selected the "Reboot to bootloader" option.
But the right way to do it is to enable OEM unlock in Dev-options... then turn off the phone... Plug in a data cable(!!!)... and holding Vol up + Vol down
Then you will get asked to unlock the bootloader. Long press Vol up... then short Vol up as a confirmation. Done...
I hope this helps other people having hard times to do that. And: DON'T FORGET THE DATA CABLE.

This is nice, May I know the model of the second hand phone?

[Q] Locked out of phone... Help?

My friend was trying to guess my unlock pattern and after so many failed attempts the only way to use the phone is to input your Google account details. The only problem with this is I had the mobile data and wifi turned off so the phone is stuck on the same screen. Any way of getting past this? If not, any way to restore to factory settings without getting into the settings menu or flash the stock rom? For the first time ever a Google search has completely failed me
I'm not sure the correct key press sequence, but I thinking holding both volume keys while powering on (from off state) should get you into the bootloader, from there you can pick recovery, and in recovery there should be an option to do a factory reset.
edit: once the stock recovery boots, it might look like a warning sign with an android in the middle. from that point you need to do another key sequence to see the options. It's been a while since I used a stock recovery, so I am not 100% positive.
perhaps try and pull the battery and let the phone restart? might let you try and use the pattern lock.
Thank you! Sorted now It was the same key sequence from the recovery screen and got it from there!
I am quite sure that the stock recovery menu does not offer any options.
I know one way which would work 10000%. Go to bootloader mode(hold both volume buttons while switching on), connect to your computer, and then use fastboot(http://koushikdutta.blurryfox.com/G1/) in the console, typing "fastboot oem unlock". This will unlock your handset(not a simlock,just the bootloader), but because of security reasons, your phone will be restored to factory settings. After that just use "fastboot oem lock" to lock the bootloader again if you want to preserve your warranty.
Stop thief!

Unlocked boot advise, how to get rid of it?

Hi ppl,
I've unlocked my bootloader and now, every time i power on the OP3, shows a screen saying my phone is insecure because it is unlocked, and offer key settings to go recovery menu, etc.
It shows about 3 seconds and continues the booting process.
Is there any way to flash my own image or something to hide it (as i did on my old moto g/g3-te)?
Thanks.
Sergio.
Nope, you'll have to live with it.
You can skip that message by pressing power button, but there's no way to remove it.

Other way of removing that message is to lock the bootloader.
Type in terminal: fastboot oem lock. this will wipe clean the userdata and you'll need to install everthing again.
You can't remove that message with the unlocked bootloader. You'll have to live with it.

immediate poweroff after locking bootloader

i think i might of just bricked my 10.
I've been going through the process to get my S-on HTC_001 device upgraded to 7.x. I used the stock Deodexed image which worked fine on 1.95.401.4, but needing firmware to get the fingerprint/menu button working.
so i update to 2.41.401.3 firmware which seemed to of flashed ok without errors.
i then found a 2.41.401.4 firmware which i attempted to update to, but got errors during flash 'FAILED (remote: 9 RU_SECURITY_FAIL zip from usb command in download mode)'. A quick search on XDA shows a bootloader lock/unlock might fix, so thats what i did... 'htc_fastboot.exe oem lock'. select yes, phone reboots and poof, phone now shuts itself down almost immediately. tried VolDown+power, but no luck.
if i leave the USB cable in, it'll keep turning itself on and turning itself off. unplug cable and the moment i power on, it'll turn off again.
anything i can do to recover it? if not, whats the solution now - pay for HTC to fix?
i started fiddling and found pressing both volup & voldown while powering on got me into the bootloader and then into download mode where i can then re-unlock the bootloader.
surprised i didnt find anything about vol up&down together in my searches.
hope that helps someone, sometime!

Tips for Nougat rooting

Just wanted to pass along some knowledge I gained the hard way when rooting my BLN-24 with Nougat (360).
1) Make sure you have the EMUI 5-specific TWRP and SU. They may have the exact same version #s as their EMUI4 counterparts, but only the EMUI5 versions will work.
2) (This one cost me a LOT of time): Once you "fastboot oem unlock", do NOT let the phone boot to system until you've installed TWRP! If you do, it will FRP lock, and the "Allow OEM Unlock" developer option will be permanently greyed out. With FRP lock on, you won't be able to flash a new recovery (it will error with FAILED (remote: not allowed)).
So after running "fastboot oem unlock" at recovery, the phone will reboot and factory reset. Once finished, shut it down, then start up with USB cable plugged in and holding Volume down + Power on. This will get you back into fastboot where you can now flash recovery or recovery2. If you screw it up and flash the wrong recovery, you'll have to RE-lock your bootloader, then re-unlock the bootloader and go through the whole process again.
Unless there's a simple way around that problem that I totally missed...
3) Don't try to re-lock your bootloader once you've flashed a new recovery. Once I did that, the device would only boot to eRecovery. (Actually, I flashed TWRP to recovery2 so I could still get OTA updates, but I suspect flashing a replacement recovery and relocking bootloader will cause the same issue).
Hope that saved somebody some pain.
Help needed After Flashing berlin twrp recovery . The phone just boots to Revovery.
Thanks for the article Florp . I need some help to fix my recovery issue.
I have flashed the twrp berlin recovery for EMUI 5.x and now my phone just boot to recovery no matter what I do.
Your help will be much appreciated.
Are you able to get to the bootloader (fastboot) screen (USB cable plugged in, Volume down + Power on)?
If so, what does it show for the lock status of FRP and bootloader?

The Bootloader screen says
Phone Unlocked
FRP Unlocked.
If you only flashed TWRP and haven't flashed a custom ROM, I would try to flash the stock recovery for your current ROM and see if that fixes it.
Thanks for the heads up. Good looking out..

N975F/DS can't Unlock Bootloader, but OEM Option ON

Hello everyone,
Sorry for disturbing you but I'm desperate, I tried everything and I can't find a way to unlock my bootloader, Here are the steps I've done so far ... First I've activated the OEM Unlock option in the dev mode, then I've turned off my phone and booted into recovery by pressing bixby boutton + Volume up, Then I choose Reboot into bootloader and so far from there I got only a screen saying to hold Bixby + Volume down for more than 7 sec to reboot the device and also got a bar code there ... I don't got the function to unlock the bootloader as everyone else ...
Also I've bought my phone yesterday here in saudi arabia, and I got the latest firmware version and that it N975FXXU1BSL7/N975FOXM1BSL9
Model N975F/DS

If you must unlock your boot loader, plug your usb into a pc, turn off the phone, hold volume up and volume down together, and plug the usb cable in.
Then you will find the unlock option.
