G950F S8 Rent A Center lock



Hey all, I came across a new one today. The s8 Along with RAC lock. The phone itself does not yet have the lock, but it will shortly, so this is a pre-emptive removal.

On any other Samsung phone removing this lock is a cake walk w ADB. Wipe the proper partitions and move about your day, the s8 is different.
Somehow they removed access to download mode and removed ADB access on the phone.

You can unlock Developer Options as normal, but you cannot select developer options once available, it says this feature unavailable. Using dialer command *#0808# I was able to gain ADB access but it showed up as unauthorized device. Using z3x I tried to reboot to download mode and all it does it reboot the phone, but this had an unintended side effect, once back on the home screen, USB debugging popped up and asked for access, so of course I allowed it. Boom now I have full ADB access. I located the lock using ADB commands and found it hiding in partition 13. Here is the partition table from the s8 G950F

Now not having root access, I know I am not going to be able to wipe the lock from partition 13, so I attempted to root. KingRoot got the closest, but still wouldnt root the phone.

In the end I was unable to wipe this partition because of how locked down everything is. I cannot even flash stock firmware to phone via download mode, because you cannot enter download mode. I cannot install TWRP because I cannot gain root access to install TWRP.

Any suggestions as to how to proceed?

    Did you try using combination file?

    How exactly do you propose I use a combination file, when I cannot get phone into download or flash interface mode?
