  3. Hi there!

    While trying to perform “Install Magisk on your Samsung Galaxy J2 Pro using TWRP” step, in the recovery mode, I keep getting the “no command” error so that I couldn’t get into the TWRP.

    Is there any workaround, or what could I have done wrong?

    Thanks ahead!

  4. Hello, for what firmware version is the twrp SM-j250g here? Because mine is ASK1, the latest firmware for Samsung J2-Pro 2018 SM-J250g/ds, thank you.

  5. I successfully flashed twrp via Odin; it says PASS. But when I try to go to recovery mode, it shows no command, and it didn’t boot to twrp. Any advice? Thank you.

    • You should un-tick the Auto-reboot in ODIN. After the flash exit in download mode and immediately boot into recovery. You should flash the Magisk in the first boot, Or Else you will lose TWRP Access.

      • I already did un-tick auto-reboot and removed the battery, then pressing vol up+ power + home to go recovery, but it still shows no command. Sorry for the trouble.

  6. I just learned that after pressing vol up+home+power, then showing “no command,” it will go to a screen with options: reboot system now, reboot to bootloader, apply update from adb….and lastly power off. Is this the recovery mode for J2 pro? If yes, then, what should I do next to go to twrp recovery?

  7. Hmm, I already did that many times but still no twrp recovery. After getting a pass in Odin, I go to recovery mode, but instead of that, it will show no command. Then after a few seconds, it will go to stock recovery.

  8. Dear, there is an error that appears ‘cannot validate device tree table cannot get fdt’ please tell me the solution of this.

  9. I tried many times but still not able to get the TWRP screen; I got the standard display,
    what I am missing,
    1: turn on with vol-, power, and home but, select the vol + to go to downloading option
    2: select the nougat, in Odin, I am using AP option, I am don’t see PDA or PA,
    3: it passes, I have turned off the auto-reboot, and immediately I used the vol- and power button to turn off and vol+, power, and home button to turn on to TWRP mode but it still loads in stand mode, I have copied the magisk.zp in my sd card.

    where I am missing, please let me know

  10. Hi, you might not respond to this comment; the post is old, but I’m desperate.
    I do everything as you describe; however, after flashing Magisk, it seems to run and says done, but after a couple sec’s it says….” failed to mount data ( invalid argument)
    then I have to start over because the boot is in the loop
    please help
