Error flashing J700M secure check fail (bootloader) - GSM-Forum

gvillagra · 01-12-2019, 18:46

Hello! I need help flashing a J700M, it came as blocked by frp lock (showing only the samsung logo and the red letters on top "custom binary blocked by frp lock) It doesn't boot

I tried flashing it so it would boot but I get errors, I tried flashing (always official firmwares) with Z3X and failed, download mode shows

Secre JTAG Disabled! ! !
SECURE CHECK FAIL : (BOOTLOADER)

And when trying to flash with odin it says custom binary blocked by frp lock

I'm sure I'm using official firmwares and it's the correct model

What can I do? Thanks

This is because the bin check from the phone is newer than the bin check of the firmware,
you can check the bin of the phone in the recovery boot,
press and hold home + vol up + power still your phones turns on and the samsung logo appears
release the power button but keep pressing home and vol up
when boot to recovery check on the top for a code like "J700MUBU3ARK7"
On This Code is three Parts -J700M-UBU3-ARK7- The First is the model of the phone (Obviosly) the second is the main version of the firmware but only need the number on the section, in this case is 3, thats the bin check of the phone, you need to flash a firmware with the same or upper binary check, The last part (ARK7) is a revision thats not really important.
you can send me a private message if you need more help.
