[Samsung Galaxy J6+ Guides, News, & Discussion] JulioManeiro:
After so many days of testing and more testing, and scared of losing IMEI, I was finally able to find a custom rom for my J6+ (J610G). (Not yet tested in other variants of J6+)

This custom, and the Resurrection Remix (RR) GSI based on Android 8.1.0 (Oreo). (Link to the original thread for more information)

Requirements:

Bootloader Unlocked (Option "OEM Unlock" checked in "Developer Options").

TWRP Recovery installed.

Memory Card with 1.5GB of space.

Very attention.

STEP BY STEP BELOW:

(WARNING: YOU WILL LOSE ALL YOUR HOME MEMORY DATA AND DO NOT RESPONSIBLE FOR DAMAGES CAUSED TO YOUR SMARTPHONE, DO AT YOUR OWN RISK!)

1. Download the rom, "system-181221-arm-aonly-gapps.img" from this link, and move the file to the memory card.

(THE NEXT STEP WILL DELETE ALL YOUR DATA)

2. Restart TWRP, tap: Wipe >> Format Data >> type "yes" and swipe!

3. Go back to the home screen, tap: Install >> Select storage >> Check "Micro SD Card >> (Go to the folder where you moved the downloaded system.img).

4. When you find the folder, tap: Install Image (All files with extension ".img" will appear) >> Tap the image you downloaded previously >> Check the "System image" and give "Swipe".

5. After installation, return to the initial screen and go to: Wipe >> Advanced Wipe >> Check "System" and touch "Repair or Change File System".

6. Touch "Repair File System" and "Swipe" after the repair, go back and touch "Resize File System" and give "Swipe". (CAUTION: If there are errors while performing this step, repeat it a second time).

7. After performing the previous step, install a root solution of your choice. (I recommend the Magisk 18.1)

8. After installing the root solution, return to the splash screen and tap: Reboot >> Recovery!

9. After the TWRP is started, configure it the way you prefer, and then go to: Reboot >> System.

10. Wait for the startup, after the startup is completed, put your language, do not connect to any wifi network and skip as many steps as you can.

11. When you get to the main ROM screen, if you do not have a navigation bar, see the next step, if you skip right to step 13.

12. Go to Settings >> Personalize >> Slide to "Navigation" >> and check "Allow navigation bar".

13. After all the above steps are followed, activate an Internet connection(Mobile or Wifi).

14. Try for a Google account, if you give a famous error of lack of certificate, do not worry as much as there is to solve! Click on this link and follow the steps.

(WARNING: You will receive numerous notifications from Google Play Services until there is an account added to your smartphone).

15. After 10min. of the above steps are performed, you can add an account and you can take advantage of all Google apps.
