My samsung galaxy s7 SM-G930F is stuck on boot loop (CUSTOM BINARY BLOCKED BY FRP locked).

I tried instaling Twrp and firmware through Odin , but i keeps giving error's cause of FRP lock.

i also tried updating through sdCARD in recovery mode but it gives me :
E:footer is wrong
Signature verification failed.

When im trying ADB it will only see my device in " recovery-mode ADB sideload"
so i cant use fastboot or 'normal' ADB .

Is it porsible to unlock FRP lock some way or turn it off in a other way ?
how can i update and install twrp or some other recovery-mode?

im really stuck here and i dont know how to install or update anything cause of this FRP lock, it locked everything and i cant open the phone to turn FRP lock off.



i really need you help here guys, so every little help will be appreciated!
Thanks.

Welcome to Android Central! I moved this from the Galaxy S forum (for the ancient original Galaxy S phone) to the S7 forum for more specific traffic.

Sorry, but we can't discuss measures to bypass security measures. Hopefully someone can come up with some other solution.

Has this always been your phone? Did you forget your password? Did someone root it and install a custom ROM at some point?

I'm sorry but playing Pokemon doesn't result you going to rooting your phone and trying to unlock your bootloader...if you don't remember Google authentication there really no way to go past that , it's a security feature so no one can steal the phone or it's information.

If you have all the accounts , fingerprint, password you should already be in the phone

In what state is the phone in now ?
Can you get to the lock screen?
Is it still in download mode ?
If it can't get to lock screen perform factory reset through recovery see if it boots up and put your password

i can get to recovery . and i allready tried factory reset many times.
but when i restart it sys FRP LOCKED and turns off again.
i can also go in download mode and connect to Odin , but when i install the phone says FRP LECKED and fails the instalation.
