how do i back up /data before wiping it?

will it wipe files such as a custom rom file
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mandeep Hundal:
In order to install custom rom you need custom recovery installed before custom rom.

However, if you install custom rom you don't have flash zip file to access internal storage through otg cable.

I flashed this recovery and when trying to boot into TWRP by holdilg VOL UP + HOME + POWER it gives a message "installing updates" then right after "no commands" and boots into old bootloader, feels like the system is overwriting TWRP by itself, I have USB debugging on as OEM UNLOCKING too.

heres the process, in case you missed something:

you must make sure auto reboot is turned off in odin

once completed, unplug, press and hold home+volume down+power then when the screen turns off switch (with all the other buttons pressed) to volume up

Hello there,

Does this custom recovery works fine with 8.0 ?

Do we still have to flash zip file to unencrypted the storage ?

After flashing does it show verification failed and says to reset ?

Will we have to reset phone to make it workable ?

Do we still have to flash custom boot img with custom recovery ?

Tell me everything I should know before flashing custom recovery so I could prepare before start.

Help to root j7 prime SM-G610F/DS Android with 7.0.

I have tried almost every method to root this phone. Can't find anyone that works. I tried the few threads here and no dice. Now, there's a person that claims that after downloading the thing from desktop.firmware.mobi got it working but I can't seem to have the same luck.

In fact on that page there seems to be 2 kinds of software for the same device, or maybe is there two kind of devices under the same name? I don't know if I have to use on7xelteins or on7xeltedd? Again, this is the j7 prime SM-G610F/DS, also it has Android 7.0, samsung experience 8.1, compilation number NRD90M.G610FDXU1BRB3 and has the Android security patch from february 1th of 2018.

Now you said it is a clone of Samsung in this case what are my solutions ?
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] LordBaal19:
Oh by the way I have a "Custom Binary Blocked By FRP Lock" in red text when booting up the phone.

EDIT: And now for some reason the phone is locked in a bootloop (it worked normal yester night) and also says RECOVERY IS NOT SEANDROID ENFORCING. Did I bricked the phone beyond recovery?

EDIT2: The correct stock firmware would be: https://www.sammobile.com/firmwares/galaxy-j7-prime/SM-G610F/XME/download/G610FDXU1BRB3/212350/ but of course the free download is "currently unavailable" and I can't really pay for a subscription. I have a paperweight now right?

EDIT3: I tried installing the stock recovery from here (because at least still opens download mode): https://xdaforums.com/android/general/root-samsung-galaxy-j7-prime-cwm-t3516777 I doesn't work. The recovery got flashed, then the phone reboots into installing a update, then it shows a huge yellow warning sign with an dead android mascot beneath and then opens up Android recovery. I wipe data/factory reset but after is done and I try to reboot to OS and it's still on the loop saying Custom Binary Blocked By FRP Lock and the it turns off.

BTW on the recovery screen the headers reads the following:

Android Recovery

MMB29K.G610FDXU1APK2

samsung/on7xeltedd/on7xelte

6.0.1/MMB29K/G610FDXU1APK2

Dunno if that's relevant.

EDIT4: Ok,

If I try to power on the phone it only says "Custom Binary Blocked By FRP Lock" the other message about the recovery is gone, but it still just turn off after a few seconds.

If I try to go into recovery it shows the "installing updates" screen again that ends up with the dead android and the warning sing, then after a few seconds it loads recovery.

If I try to go into download mode it does so without issue.

What should I do from there?

You know, I had, but since I saw it didn't do anything (apparently) then I disable it. After the phone discharged and turned off the error came.

What can I do now? Must I flash a stock rom?

EDIT: Oh my I just flashed the stock room for the phone (after 3 a days download from updato), exactly the one for it (even the original country and all) and apparently I came back from the dead! I won my medal of necrotech?

EDIT2: Now, with this model and software of this phone, can I follow the instructions of the OP to root safely?

EDIT 3: The phone updated a lot of times (thing that didn't do before) and now is sporting Oreo (8.1.0) with a security patch from dec 1th 2018.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] LordBaal19:
1. Ok, so the phone as a fresh 8.1.0 system (just flashed the 7.0 and then it updated OTA in a matter of minutes). I enter the phone, enable the developer mode, enable OEM Unlocking.

2. Then I put the phone on download mode, flash the TWRP recovery disabling the auto-reboot on Odin so it doesn't boot to system automatically. This seem important since otherwise the recovery goes back to stock.

3. Then, to get out of download mode I press vol. down and power keys at the same time and the phone turn off. Then I turn on the phone into recovery mode, once in there I swipe into write mode and go to Wipe and select Format Data, type down yes and it says it's done. I go back to TWRP main menu.

4. I connect the cellphone to the PC and drag the no-verity-opt-encrypt-6.0 file into the storage that pops up. Then I select Install and install the .zip file without selecting Signature verification or Reboot after is complete. It says is done installing and no errors seems to occur. I employ the button to wipe Cache and Dalvik.

5. Then I try to reboot to System, and choose to Do Not Install the TWRP app, and... the Phone is on a loop. It shows the Samsung Logo and reboots, once and again until I interrupt. I can enter both download mode and TWRP recovery without issue. What I have done wrong?

EDIT: Re-read the whole thread, I just flashed everything stock again since couldn't find a way to boot up to system. Don't know what I did wrong. Perhaps is because I didin't choose USB debug or it could be kernel issues that DarkLord1731 mentioned on a post 21st October 2018.

Maybe it just can't be done and rooting the J7 Prime SM-G610F/DS with Android 8.1.0, Samsung Experience 9.5 with the December 1th 2018 security patch is impossible yet.

Since you are on Oreo you'll need to install magisk or a custom kernel in order to bypass dmverity. I'll add this in the OP

Alright then, at which moment should I install magisk or the custom kernel? Which one is more recommended?

Which one do you recommend? At which point do I have to install it and then I don't need to install no-verity-opt-encrypt-6.0?

2. Then I put the phone on download mode, flash the TWRP recovery disabling the auto-reboot on Odin so it doesn't boot to system automatically. This seem important since otherwise the recovery goes back to stock.

4. I connect the cellphone to the PC and in storage I select Mount USB. Then drag the Magisk-v18.0.zip file into the storage that pops up on Windows. Then I saftely remove the device in Windows and go back to the main TWRP menu on the phone. I select Install and install the .zip file without selecting Signature verification or Reboot after is complete. It says is done installing and no errors seems to occur. I employ the button to wipe Cache and Dalvik.

5. I go back again o Wipe and select Format Data, type down yes and it says it's done, again.

5. Then I try to reboot to System, and choose to Do Not Install the TWRP app, and... SUCCESS!! The phone starts again, I config everything and then Magisk is there in the apps. I tried with an app that requires SU and it works!

Cant access data in twrp with no encryption and latest magisk installed.

im using stock tw oreo latest build.

i found this while searching for the sol.. Dev may you please take a look.

I don't know if you faced this issue already, but some people couldn't mount /data partition in TWRP even though they removed encryption. Why this happens?

Explanation:

Samsung added quota support in their oreo update for the /data partition. Means a TWRP update with proper quota support is needed to get this new feature to work. Till now, many developer simply disabled this feature again on their kernels (so they can mount /data without issues on the old TWRP).

What I did:

I updated the tree with the latest files, kernels and so on. Including the above mentioned quota support.

This TWRP version works on stock and supported oreo kernels. Older kernels (which removed quota to fix mounting problems) won't work here. Please advice your kernel developer to update his kernel with the changes.

Hey!

I have overcome the twrp problem on j7 prime with Oreo stock.

First, on the twrp menu select the "wipe" menu then select "format data", swipe and type "yes"

then return to the initial twrp menu, select "install", see if the internal storage is mounted

And then,

If you want to install the custom rom (Like DotOS or Lineage 15.1 from DarkLord1731)

Do the usual steps after the internal storage is mounted or do as in the quote above

Twrp 3.2.3 has a problem with internal storage that is not mounted
