flash stock rom through odin

OEM unlock must always be ticked if you are using diffrent recovery to root. Or else you will be FRP locked.

flash stock rom , always leave enable oem unlock enabled
Flash official rom with Odin, don't worry previous setting ,app & data is not lost. After flash reboot go to developer option enable "usb debugging" and "OEM unlock" (don't forget..) before flash custom rom/recovery again

Sure it will.., I have same problem like you after i disable oem unlock in dev option. My device SM J700F is rooted and use twrp recovery can't boot (bricked) because frp locked in reboot .Just download official rom and flash with ODIN and be sure only Auto Reboot and F. Reset Time option is selected so your data is not wipe when flashing .
Disabling oem unlock make device permanent brick?

Yes, if we want using custom recovery and root kernel we must enable oem unlock and usb debugging, disable it may cause bootloop and bricked (custom os blocked by frp lock) :good:
Suppose i am enabling oem unlock and developer options. Root and add gmail account.will boot loop or custom lock by frp error come? Samsung added patches to prevent rooting mobiles? Has anyone successfully rooted this mobile j700f?

I used 3 google accounts ,added in my J7 that's it doesn't make the frp lock,, the only cause frp lock in samsung is oem unlock, just enable the usb debugging and oem unlock. Rooting and custom rom will work.. on that
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.

Hi, I want to root my Samsung SMG930f, Build: G930FXXU2ERH1, i tried it with cf auto root , error = FAP Blocked.
What do i need, which Tool and/or file...however. Im an absolute Beginner! Dont know what to do...(sorry 4 my bad english)
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.

Guys, I tried to flash TWRP recovery on my A7, build number xxu1asa4.
I unlocked OEM first, then booted into download mode to install system and suddenly disconnected my phone from PC:
"Custom binary blocked by FRP lock"
I have locked OEM now, no recovery access, and there is a soft brick in my smartphone. :crying:
Does anyone know how to fix that issue?

I am also experiencing this problem, the solution is to take in a technician or authorized Samsung.

You should've not unlocked the OEM, but also disable the FRP Lock. Initiating a factory reset from Settings (which will force you to enter your Samsung Account password) would've done the trick.
To get your Phone running again, reflash Stock ROM and just repeat the process.
Phone will not boot because of "Custom binary blocked by FRP Lock" What do i do?
So I installed TWRP then Magisk then some modules and I reboot to install the modules and like a complete idiot I turned OEM Unlock off so FRP has tripped and I have no idea how to unlock it. I can't get in my phone but I can get in download mode. Odin3 v3.13 will see my phone and can interact with it. What do I do?

You need to flash it back to stock firmware then enter the google account info after reboot to release the FRP lock. It's only a problem if you don't know it.
