    Bricked Phone trying to flash TWRP while Custom OS was already there. Please Help.

    Hello everyone. I have an S8+ that is basically bricked and need to know if someone can help me repair it:

    Please keep in mind while reading/replying that I am quite illiterate about thees things but tried to follow guides. I've reached a point now where I can find no guide to help me out of my problem, hence I turn to you:

    Here is the situation: I root my Samsung Galaxy S8+ (Exnynos, SM-G995FD, Saudi Arabia) and all was fine, until I tried to encrypt the device. It failed and told me I needed to wipe my data, which it would fail to do with TWRP, and then go back to that same screen. Someone told me I may need to wipe and reinstall my system files, which I did successfully and all was fine again. I reinstalled Stock Android from an online download, and all was good.

    Then I tried to reinstall TWRP recovery again. I think this is where I did something stupid. I suspect now that I already had the "stock android" in my recovery mode and I guess I can't just flash TWRP right over it. In any case, TWRP flashed but then nothing happens when I try to go to recovery mode, and the phone is stuck on the "Samsung Galaxy S8+ Powered by Android Screen."

    So I though "Okay, I'll flash Stock Android back with Odin again." Nope, it won't work. I get a FAIL! from Odin every time. I tried to flash TWRP again, and same. Download mode still works on my phone, but Odin always fails. Recovery mode doesn't do anything since I tried to flash TWRP after the Stock Recovery mode was still there.

    So now I have an S8+ with an not-working-at-all recovery mode, a download mode that fails to download anything, and a stuck boot screen if I don't do anything.

    Can anyone please help me get my OS working again, preferably on a root? Thank you so much.

    P.S: Here is the Odin Error Log:

    Still unsure how to safely root now though. Should I try flashing TWRP? It didn't go so well the first time...

    Can you post the XDA link again as not working
    Will be useful to know the solution.

    That should work. Basically, I had to exit download mode as soon as I entered it and enter it again right away.

    Would you be able to help me root now? If I try installing TWRP, I get a signature verification failed message and stuck in a loop again. Any idea what is going on?

    The TWRP file you are looking for is this one:
    https://twrp.me/devices/samsunggalaxys8plus.html

    It is installed with Odin as you would a single firmware file (AP of Odin)

    The signature verification is linked to your root method.
    I would use cf-autoroot and then install super su from the Play Store.

    Thanks. I needed that, plus a full wipe and a no verify opt encrypt file to be flashed. All is well now.
