I was on Ephemeral Mate 8 | International B180 ROM on my NXT-L29, and everything was ok.
But then I made some mistakes trying to flash a B321 ROM from AL00 and after some faillures it seems I got it installed (or sometinhg like it, as seen on screenshot)
However I lost twrp and root, and I am not able to flash twrp again, because when i try do fastboot flash a twrp img i get a failled message (i think it is writing not allowed)
When on bootloader menu I get 2 messages: Phone Unlocked and FPR Lock (or FPK?)
What does it mean? Do I need to unlock bootloader again? How can I get twrp (or other custom recovery) back on phone?
Any hints would be welcomed
Many thanks
i have the same problem with b180.. i just wanted to start a new thread but found yours... i hope someone can help

Hi, sorry for you guys.
so first Try to unlock bootloader again
Posted about this on another thread. If you have FRP locked you need to boot the phone, sign out of Huawei ID and Google ID under Accounts. You may get a notification that this will disable device protection features. Also, under Developer Settings, make sure OEM Unlock is checked. Then reboot to fastboot and it should show FRP unlocked.

I will give you a real solution... First of all save all your data... Do a factory reset.. After that.. Go to menu and activate usb debugging.. Then dial... *#*#2846579#*#*..select usb connection and than manufacturer mode...NOOWWW connect your phone into fastboot... Flash first the insecure boot image b321 via adb... Then recovery.... Excactly this worked for meee... Plz let me know if it worked....

Hi.
My mobile is pattern locked and I forgot the pattern.
I don't have had activated usb debugging or OEM unlocking .
I tried flashing it with twrp recovery but no luck.
I don't want to lose my data from the mobile.
Is der any other custom recovery apart from twrp for Samsung j710f?
Thanks

I don't think there is, and even if there was you would still have to enable OEM unlock before flashing it.

So this OEM unlocking is mandatory for flashing any custom recovery?
Yes. It has to be enabled to allow flash of binarys not signed by samsung, otherwise you will be forced to download mode to flash back stock firmware.

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.
