    Unhappy Custom binary blocked by frp lock after accidently disabling Dev. Option on Rooted SM

    Hello,

    Phone:
    Phone is Samsung Galaxy S8, "SM-G950F".
    Android 8.0 Oreo
    I rooted my phone 2 year ago. It has Magisk latest version 20.

    Problem:
    After doing some modification, I accidentally forgot that the Developer option OEM unlock was KEY, and disabled developer options.
    It shut down after being out of battery.
    Now it won't turn on and when I try to charge it it just endlessly shows the Samsung Galaxy logo with the message "Custom binary blocked by frp lock" before shutting down and turn on again.
    I can not access recovery mode.
    I can access download mode (info shown at end of post).

    Question:
    1) How could I bypass this lock?
    2) Can it be done without loosing all my data? Or can I back it up before?
    3) Can it be done without loosing root? Or can I put back root after?
    4) What would be your general suggestion to recover the complete use of my phone it was in before that mistake.

    Thank you in advance.

    But I am still looking for confirmation that my data is lost and that I have to go through the whole thing (flash stock firmware then root) again

    EDIT: Oh, accidently made double thread. My bad! Thank you.
