[Samsung Galaxy J7 Guides, News, & Discussion] Vi3tDroidz:
As I begin rooting process for my J710, and realize that the J710 is still fairly new so I thought I write this post and share my notes with everyone to help your transition goes smoothly.

First thing first, some safety tips.

Know your stock firmware. In this case SM-J710 is the min requirement

Have a stock firmware file downloaded on your PC. There's nothing for US right now, but J710 is not region lock so it matter not which version you chose on Sammobile

Make sure your current and new version match up as much as possible. So J710 should be the first 4 that need to match

Created a Folder on your PC for J710, and organize everything in one place. Samething with phone microSD card

Try to make a habbit out of keeping track of your process. It will help you out alot when things goes wrong and are looking for help. Or if you need to go back and see where you make mistake. Especially useful if you are new at this. Dev can't help you if you don't know what you did yourself.

10min rules. Always give the phone minimum 10 min to boot the first time before you disconnect the battery. Sometimes it just take longer, but 10min is a good start for first booth.

TOOLS you will need.

ODin newest is 3.10, but other version will be fine

Stock USB cable that came with the phone. This will save you the hassle of downloading USB installer, and it makes data transfer from ODin to phone alot safer.

TWRP for J710. right now it's only beta phase, but I beleive its 3.02.

Superuser zip files to be flash upon successful installation of TWRP

BACK UP DATA: With the app you can use ES explorer and back up to you microSD.

With the phone, just plug in to your computer, Copy the phone folder, and create a subfolder on your PC and name it System then paste everything onto that folder. After rooting is done. Re-install the app again, then copy your system folder onto the new system folder of your root phone. Restart your phone, and all your previous login and layout will there the way you left it.

Technically you only need to copy the ANDROID & BACKUP folder for your apps. But the above methods will back up all your media along with apps info, and it alot faster.

I recommend using ES explorer because it will does all the modification for without having to go through TWRP once you have rooted enable. Just enable root, and whatever you want to modify, place it in the correct folder of the phone SYS. Reboot and its done. You won't have to go through TWRP and risk bricking. You can save your modify rom in a zip file and share up here. It like being a developer for dummies.

So before you begin. The number 1 thing you should have is the firmware. SM-J710 from Sammobile. With that being said, I have found 2 links for rooting. They are both similiar process, but the one from XDA is for SM-J710F. and the link from Androidinfo is for SM-J710MN. Depend on your choosing you need to have a backup firmware from the method that you chose.

Now that you have the stockfirmware, and your phone is not the F or MN series. Flash the stock firmware of the method that you chose, and go with the rooting process for that method. here are the links:

This rooting method is working mostly with ODin, odds of you bricking your phone is about the same as winning a lottery. With that being said, make sure everything that you plan on flashing is from J710 and you should be fine.

The J7 is more like an opensource phone from Samsung. It does not have a lot of restriction like the other models such as S series. But you are working with a beta version of TWRP so it might not work out the first time around. If that is the case, flash a different firmware model or wait for a stable version. It not the end of the world if you phone is rooted.

Backtrack to beginning: Flash the stock firmware to begin the process again. WIPING DATA before any process is always a plus.

using ODin: Flash Firmware on "BL" for new version, i forgot which slot it is for the older version

Flash: TWRP and SU on "AP" slot for new version

INTERESTING FACTS: I ran across a thread online that mention backing firmware via Odin is possible. Hopefully someone here on XDA might have an idea on the methods, if such a thing exist. I thought I share this. If only I remember where I ran into that post.

Last notes: During the rooting process, I recommend letting the phone reboot completely as you progress through each phase of the process. the reason for this, is so it will help you identify if the TWRP is not installing, or the kernels is incorrect, or the SU.

Your phone will bootloop if TWRP does not optain write priviledges.

Your kernels will always install, but if TWRP does not have privileges the phone will not boot.

Should you were able to get TWRP, and Kernel to install properly, but fail to get SU to install. You gonna have to play around with other SU version. I would do a TWRP back up should I was able to get it to install, before moving on to SU. This way you won't have to start from the beginning if it doesn't work out.

With that, I leave the rest in your hand. Goodlucks
