2. How to unroot, and to totally reset and restore phone back to stock ROM just in case.

Many thanks!

I have exactly the same questions.

The tutorial on the first post is awesome, but it definitely lacks back up / restore of the stock ROM.
[Samsung Galaxy J7 Guides, News, & Discussion] aniesh1114:
U need to have a custom recovery to take complete backup of a ROM. U can download stock rom from sammobile, which u can flash though odin if required.

After installing twrp-3.0.0-0-j7elte-j7elte.img.tar, it asked a question about partition read only and something related to official updates.

But it appeared only for the first time.

I didn't confirm it, what was that?

And, Is it better to use the stock ROM or should I install a custom ROM?

Here is my devise info :

SM-J700/DS

Made in Vietnam
[Samsung Galaxy J7 Guides, News, & Discussion] aniesh1114:
I am not sure about partition as i don't own this phone anymore and nor i have flashed twrp 3 on my phone.

Custom Rom is good as there are hardly any bloatwares in that. This custom roms are based on the old build by samsung however u will miss new features and security patches whenever samsung includes in their latest build.

---------- Post added at 02:57 PM ---------- Previous post was at 02:53 PM ----------

Maybe the variant J7008 have really no option for OEM unlock. Sorry bro.

By the way, what is the chipset of your device, Snapdragon or exynos?

I think available twrp and custom roms now only supports exynos variants. J700H/F/M

---------- Post added at 03:00 PM ---------- Previous post was at 02:57 PM ----------

Its not advisable bro. Since the custom rom your using now is deodexed and debloated.

But you can try it since you already have backup in cased of boot loop :) and report it here the outcome :)

---------- Post added at 03:02 PM ---------- Previous post was at 03:00 PM ----------

Hmm, i think snapdragon chipset is not supported. But you can try the steps in first post bro.

Regarding Android 6.0, there no marshmallow update for J7, only the CM13 but not stable enaf as daily driver :)

I need help for uninstalling TWRP recovery without flashing stock rom

I need help anyone,plssss.Im using the Sm-J700h.It runs on 5.1.1 Lolipop.I eooted it a few days ago for usinv Xmod,but unfortunately it doesnt work due to enforcement in samsung,even after trying a lot.So,I unrooted my J7 and deleted everything related to root.Now,when I click software update,it says ur device has been modified in an unauthorised way and .......Means I cant update to Marshmallow now!!!It can roll out anytime.And in device status it says Custom.So i did a complete wipe through TWRP recovery.Everything was gone,all my apps,data settings...Still the Status is custom.I tried doing many things from Xda forum including the removing sd card and wipe cache technique.It has just been 1 month since I bought tgis phone and I cant let it get destroyed.Later on I found that it was TWRP recovery for which the device status showed custom and I coudnt update.Pls tell me How I can remove TWRP recovery and change it to stock recovery without flashing the whole rom???I can flash the stock recovery file if it works,but I searched a long time but no one has the stock recovery file.And I cant flash the Stock Rom because my Baseband Version is not available in anywere.My Baseband is J700HXXU2APC1 .I cant find any rom with that baseband.One thing to mention is that Im from Bangladesh and I bought it from here.Pls tell me anyone how I can get Stock Recovery back without flashing stock rom so that I can Be able To Perform OTA updates again.Pls help me.

[Samsung Galaxy J7 Guides, News, & Discussion] daishi4u:
You can put it back to stock using Samsung's smart switch software on a PC... But it still won't do ota updates afterwards because of the Knox protection crap. The good news is that you will still be able to update, Just have to use smart switch to do it from now on
[Samsung Galaxy J7 Guides, News, & Discussion] Ahnaf_AdilAhnaf:
Ive searched samsung smart switch pc but im unable to find any download links.Pls give me the Download link for Windows 7.And also one thing,I didnt understand what u said about knoX protection,cant perform OtA afterwards.Pls tell me how I can get My device to recieve OTA.Cause Marshmallow may arrive anytime.I could have flashed the Stock Rom but the My Baseband Version J700HXXU2APC1 is not available anywere.Ive searched for a long time but coudnt find it.If u can find the stock rom of my baseband and give the link for downloading my Baseband Firmware,then Ill be very happy.Pls help me.Its been only 40 days since I bought this phone.I cant lose the OTA updates.

[Samsung Galaxy J7 Guides, News, & Discussion] daishi4u:
Here's the link for smart switch...

http://www.samsung.com/us/smart-switch/assets/downloads/Smart Switch PC_setup.exe

But, like I said, even going back to complete stock will not allow you to receive ota updates anymore. The Knox protection hasn't been broken from what I could find... This tells the phone that you've modified it and won't allow you to update anymore. You can still update through smart switch though. Just google how to update your phone using smart switch once marshmallow comes out.

1) Download Odin, TWRP Recovery & SuperSU file to your laptop/PC.

2) Turn off your phone.

3) Go to download mode (by pressing Volume down+home+power buttons at the same time for about 6-8 secs)

4)Press the Volume up button to continue.

5)Open the ODIN file you downloaded on your laptop/pc.

6) Connect your phone to your laptop/PC through USB cable.

7) When ODIN detects your phone, It will show added in the Log.

8) In ODIN click on AP and then select the recovery file you downloaded.

9) Click on start. The flashing process will start.

10) If the flashing succeeds, ODIN will show 'PASS'. That means the recovery flashed successfully. It will boot into recovery.

11) Swipe to Allow Modifications. Click on Reboot then System.

12) Copy and place downloaded SuperSU file to your external SD card.

13) Turn off your phone.

14) Reboot to recovery (by pressing Volume up+home+power buttons).

15) The recovery will start. Select 'install zip'.

I'v done all this so far but i can't find this install zip thing ! help please =)
