  1. “Select Wipe->Advance Wipe->Select Cache Data.”
    I can see on this step these menu options only:

    – Reboot system now
    – Reboot to bootloader
    – Apply update from ADB
    – Apply update from SD card
    – Wipe data/factory reset
    – Wipe cache partition
    – Mount /system
    – View recovery logs
    – Run graphics test
    – Power off

    I have chosen “Wipe cache partition,” then I was returned to the same menu.

    “Return to Home of TWRP select Install.”
    This I don’t understand, how can I get to this?

  2. “Once the file is loaded into the device, reboot your device.”
    But Odin reboots the phone itself, I can’t reboot it.
    “If you installed TWRP, Don’t turn on your mobile. Immediately, move to Magisk Installation steps.”
    But the phone is already rebooted, i.e. turned on.
    From this point, discrepancies begin between my results and your steps. After “Boot it Into recovery mode”, I don’t see “TWRP Recovery Mode”, I see the system menu that I described before.

  3. I want to root my phone, can anyone that has experienced full success comment? I love this phone, want to install Dolby atmos or resurrection remix rom. Thank you, thank you, thank you.

  4. Hello,
    Android Oreo
    Odin 3.12.7
    but… Odin fails!
    Any hope to flash successfully another way?
    PS: screen capture on-demand.

  5. Hi,

    I also tried to root the phone and got into the same troubles as Leonid. I uploaded the TWRP with no error. During restart, I pressed Vol up + Power + Home, and the default Android recovery showed up instead of TWRP recovery mode. I also used the right twrp file. Is there a solution?

  6. I followed all the steps (using the latest versions of everything, i.e., USB-drivers/Odin/TWRP), but I get a similar error message as zblerx reported June 14th (only one digit differ 5 vs. 3) on display:
    Odin states the following:
    RQT_CLOSE !!
    Complete(Write) operation failed.
    All threads completed. (succeed 0 / failed 1)

    My A3 runs the following:
    Build number:

    I only want to root my device, so is there some other method?
    Is my assumption correct that if I only want to root the device, I do not need to use Odin/TWRP method, and I can achieve the same by installing the latest version of “Magisk Manager” according to this?:

      • I downloaded the TWRP again from the link above.
        But I got the same error.
        Are you sure you updated the new TWRP file as it is binary identical with the one I downloaded before entering my first comment on Sep 30th:
        C:\Projects\Android\A320FL>FC /B “samsung_sm-a320fl_Oreo_TWRP_old.tar” “samsung_sm-a320fl_Oreo_TWRP.tar”
        Comparing files samsung_sm-a320fl_Oreo_TWRP_old.tar and SAMSUNG_SM-A320FL_OREO_TWRP.TAR
        FC: no differences encountered

          • Thanks for the support so far!
            However, as I have the A320FL and not the A320F, do I dare to use that TWRP file?
            From the file name of the A320F file, it seems to be version 3.1.1-1, and I found another 3.4.0-0 from the official twrp site.
            So, what is your suggestion? Should I first try the 3.4.0-0 and then the 3.1.1-1 if the first does not work?

  7. I tried it now, and it works, ok!
    Rooted an old Galaxy S6 and the same method (but other TWRP), and that device is also rooted now!

    Thanks a lot for the support!

  8. Hi,
    I have A3(2017) SM-A320FL.
    The goal is to recover some deleted files.
    Therefore I want to root.
    USB debugging is on; USB configuration MTP (developer mode)
    BUT: the phone is just charging. I can’t connect with USB.
    No popup or something…just charging.
    So, is there a way to root via the SD card?

    Thanks for the support,
    hopefully, Martin

  9. Hi,
    I’m not able to load the TWRP with Odin on my device. The log shows:
    RQT_CLOSE !!
    Complete(Write) operation failed.
    All threads completed. (succeed 0 / failed 1)
    Do you have any idea where the error is coming from?

    Thanks a lot!
