A few days ago, I had an RFP reset experience on a Samsung Galaxy A5 2016 (SM-A510F/SM-A510FD) that stuck Google account verification. The first thing I did was take the phone to Recovery Mode to identify the firmware version. I saw A510FXXS8CSF6 on the top screen, S8 is a binary (security lock applied on the bootloader of Samsung devices) running on Android 7.0. If your phone shows U8, S8 and U8 have the same binary.
So I would like to share a short story of the experiment to unlock Samsung SM-A510FD/SM-A510F with S8 and U8 binary.
First Try - Bypass FRP
I was unlucky to follow the FRP bypass video from Zarachiel Nugraha, downgrade the phone firmware from A510FXXS8CSF6 to A510FXXS8CSC4. Both have binary 8 but the A510FXXS8CSC4 has a low Android Patch Level Security. S-Voice seems, but on the Terms of Conditions page, there is no active link for access to the Samsung Account login page. I decided to find another solution.
Second Trial - Flash with Odin and Combination Firmware
Flashing is risky but worth it. The phone successfully unlocked Google account verification by flash using Odin and Combination Firmware Binary 8 from Z3X.
- Flash phone with Combination Firmware.
- Flash phone with Stock ROM FRP Unlock.
- Flash phone with Official firmware.
