Bootloader Problem !.

hi guys my tablet was like bootloop. when I unlock bootloader after restart again by itself again locked. for this I can not install stock rom, what problem ? pls help.

"custom binary blocked by frp lock"

Edit: No one replied with a good answer so i reinstalled stock recovery while keeping root and turned off OEM Unblock and it bricked my device with "custom binary blocked by frp lock" and i am currently fixing it with Smart Switch initialization. Moral of the story: Never disable OEM Unlock
(A5 2016)
Does this happen after you turn off OEM Unlock because the recovery is not stock (TWRP is installed) or because the device is rooted or both?
If after rooting with https://forum.xda-developers.com/sa...overy-samsung-sm-a510f-fd-exynos7580-t3314399 i flash stock recovery and turn off OEM Unlock will i still get this message?
Thanks!
Please note that i had the "custom binary blocked by frp lock" error but i fixed it with Smart Switch initialization. I want to turn off OEM Unlock for security reasons

just flash previous firmware version which u have in your phone before frp lock.
nothing to worry its not bricked.
only ensure version u are going to flash is same as before , flash via odin and enjoy

I already did it, my question is that if i remove TWRP and install the stock recovery while keeping root, will disabling "OEM Unlock" show "custom binary blocked by frp lock"

Help
I am going through a similar enigma. I have S7 Edge. If I log in with Google and then turn down unlock on will I get custom binary error? Any help would be greatly appreciated.

@CrystalGTX
This is an old thread, but I am having the same problem; (stupidly) unchecked OEM Unlock. Reboot, and now I have "Custom binary blocked by FRP lock".
When you say "fixed it with Smart Switch initialization", does that essentially mean reflashing firmware?
And as a result, erasing all data?
I've read that flashing stock firmware can save the hardware, but I'm much more concerned about the data; I need my contacts, photos, txts, etc.
EDIT: Err, shoot. I see now this was posted by a Guest, so I doubt the OP is going to give me a response. Anyone else help?

you just install frimware latest one and activate it with ur google account. than oem unlock than flash with root via odin

Im having this issue with my phone i accidently ticked off the oem unlock in development settings I put the phone in download mode because thats the only mode i can get into (recovery and regular boot does not work) when I connect to pc now it shows up as usb serial device in ports or it shows up as samsung modem and odin wont flash the firmware

I never had any issue. You get a single recovery.IMG and flash it. The s6e+ is tricky. You should have a custom ROM or what you want to flash ready and just flash twrp, boot immediately into it. Backup phone via twrp then wipe it and flash custom ROM. This will ensure you don't get any real issues or fpr blocked. Also use XDA tuts or get help here, YouTube can go good or bad. Recovery images are device specific. If you have f and flash t it won't work. You have to really look at what you are flashing and match model information. I'm seeing a lot of people fpr blocked and in trouble. I might go make a little walkthrough

Bricked N900V unit that cannot be Unbricked.

Hello people
I've got this problem since 4 days and I have done everything with no luck.
I have this N900V that is stuck in the boot sequence.
I've flashed thousand or ROMs (like 3 stock ROMs) and they flash as usual.
The problem is that I have to make a factory reset and Everytime I try to do it it gives me an error: MDM doesn't let me factory reset the phone!
I try to replace the recovery with TWRP and I can't cause the bootloader is locked.
I can't unlock it cause I have no root access.
I'm lost here and I don't know what to do. Please, help me you gods of XDA!

[SOLVED] My Mi A1's system is destroyed and locked, please help

Hi! Today, I decided to try to install GCam on my Mi A1 running the August 2018 update. I have successfully installed the GCam Mod on my Mi A1. But when I wanted to lock the bootloader, I accidentally wiped clean all my data and now there is a pop-up stating my system has been destroyed. I cannot boot into the stock ROM, however, I can enter fastboot. So, I tried flashing the stock ROM into my phone using the XiaoMiFlash tool. It failed and showed me an error message. That error message can be seen here: imgur.com/a/naxM0WB (sorry I haven't posted enough posts to grant me URL sharing). I assume the error was caused because my phone has a screen lock. Also, the ADB drivers don't recognize my device and my phone also failed to enter EDL mode. BTW I'm a newbie to this and I cannot do anything that will involve me opening the device.
Can anyone please help me flash the stock ROM?
Thanks,
KN
SOLVED: So, it turns out that you need to unlock your device with Mi Unlock and everything will be back to normal.

You have locked your bootloader with modified system. Unlock it and reflash stock ROM.
