  1. Bonjour, je suis actuellement en train de rooter mon téléphone (SM-J320F), mais le fichier TWRP que j’ai téléchargé (Via le tutoriel donnant différente version -> J’ai choisi la J320F) s’appelle recovery, et c’est une image disque en .img
    De ce fait, je ne peux ajouter le fichier via Odin car les seules propositions données sont des .tar .md5 .smd .gz et .tgz
    Pourriez vous m’aider ? (Assez rapidement car je suis en plein root du téléphone s’il vous plait)

    • In English this is better ^^ :

      Hello, I am currently rooting my phone (SM-J320F), but the TWRP file I downloaded (Via the tutorial giving different version -> I chose the J320F) is called “recovery”, and it is a disk image in “.img”
      Because of this, I can not add the file with Odin because the only given suggestions are “.tar” “.md5” “.smd” “.gz” and “.tgz”
      Could you help me ? (Quite quickly because I’m in full root of the phone ^^’)

      • The file you download is a .tar file. Do not extract the tar file. you should flash the .tar file directly. If you extract the .tar file, it will give you the .img file.

    • Le fichier que vous téléchargez est un fichier .tar. Ne pas extraire le fichier de tar. vous devriez flasher le fichier .tar directement. Si vous extrayez le fichier .tar, il vous donnera le fichier .img.

  2. Hello. I tried your procedure, the installation with ODIN was successful, but after rebooting in recovery mode the phone does not load the recovery, the display keeps showing the android symbol with the words “downloading” and “don’t turn off-target.” Any tip?

    • Reboot to recovery mode. Press Volume Down+ Power Button to exit download mode and Press Volume Up+Power Button Enter into recovery mode and flash Magisk.

  3. Hi, I’ve been given the sm j320fn by a friend, so but after a factory reset, it won’t allow me to use as old Gmail account as been forgotten, so how do I bypass? Can I flash using spft instead of Odin as no USB debug on, pc/Odin won’t detect, please advise. Conner.

    • If you do a hard reset, you don’t have any data. So, Flash the firmware using ODIN and login with your Gmail Account. Google Account recovery can help you to recover the account.

  4. after clicking AP on Odin, then pressing the start button, there was a message as pass in Odin, but after that, my phone automatically takes the restart, but it wasn’t rooted; what can I do?

  5. I rooted my sm-j320F with the steps, and thanks to you, it was successful. And now I need to flash the best Rom compatible with it any idea??.

    • There is no official Custom ROMs are currently available. But, If you want to try Custom ROMs, begin with Lineage. It will work well with fewer issues. But, Most of them don’t work well with VoLTE. So, If you depend on the VoLTE network, stay with the stock firmware.

  6. When I start the recovery mode, the menu does not show the item “Wipe-> Advance Wipe-> Select Cache Data” but “wipe/data/factory reset and “wipe cache partition.” It seems it’s in a normal recovery mode, not in special TWPR recovery mode. May help? Thank you.

  7. Hello, I did everything as explained in this tutorial, but then when installing Magisk v12.0 (update from external storage) I get a failure:
    E: failed to verify whole-file signature
    E: signature verification failed
    and this happens a couple of times.
    Then, it says:
    Install from sdcard complete
    Applying update complete
    and it reboots although I un-ticked auto reboot in Odin3 v3.11
    Any ideas? I’m quite desperate!
    Thank you!

  8. Not able to reboot into TWRP recovery mode. It says “no command” when I try to enter recovery mode and then shows a different menu than what you mentioned in the blog.

  9. Hi, please help me. Stuck in recovery mode. it’s not possible to”Return to Home of TWRP select Install.” there is no “install option.”

  10. So I have a problem. I have an SM-J320F. I turn on both OEM unlock and USB debugging, I download ODIN and the rest of the files, go into download mode, and flash(Auto-Reboot is off). The flash completes within seconds, and ODIN gives “Pass!” and the progress bar in the download mode appears filled. No errors, no anything. I turn off my phone and boot into recovery mode. I see the Recovery mode that I’ve always had – it’s like TWRP wasn’t installed, but I flashed it. Attempted the same flash at least 5 times. I tried different stuff like taking out the battery after the flashing finishes and then booting into recovery mode – no luck, I still have the default recovery. Any clues to what may be wrong, I downloaded the correct files and the TWRP tar for the SM-J320F(my phone). Please help.
