Samsung Galaxy J2 Pro is a Mid-Range phone; Samsung Stopped updates from their side. But, If you use Lite weight Custom Roms, you can expect a considerable performance Improvement. So, If you have little knowledge in tech, I advise you to Root and uninstall some unwanted apps. You can also flash some Custom ROMs. If you flash Custom ROM, check what is working and what is not working. It is wise to use Some Official Custom ROMs like Lineage. If you accidentally bricked your mobile, you can repair by flashing J2 Pro Stock firmware.

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!
Can you boot into TWRP? If you can Boot inro TWRP, flash Latest Magisk.
Purila.
If this is your first time on Rooting, you should read the guide fully to better understand the steps.
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.
It can support all versions within Nougat. So, IF your mobile is on the Nougat version, you are good to go.
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.
I think during the flashing something interrupted. Flash the TWRP again and do the Recovery boot in One go.
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?
You boot into stock recovery. Did you get the “PASS” in ODIN?
yes, it shows PASS
You should boot into first boot into recovery, Or Else you will lose root access. So, After getting “PASS,” You should exit download mode and boot into recovery first.
The new file is not working. I put it in ap in Odin and says md5 error! The binary is invalid.
Sorry for this. We updated the correct file.
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.
We update with one more General TWRP Recovery file. Try that one.
I hope the new file works
