Can I install a previous version of Android on my J7 2015? - Samsung Galaxy J7 Questions & Answers

So, I have a Nougat (7.1.2) custom ROM. I just want to flash the stock one (marshmallow 6.0.1). Can I just simply wipe on twrp and flash? Thanks.

It should work. I did this to upgrade my radio files to the latest.
Note that you'll lose TWRP and root.

Install 5.0.2. ROM while being on 5.1.1. Stock

hi guys,
i'm on stock 5.1.1. On a s6 sm-g920f, rooted with unikernel, installed twrp. now i'd like to install axis rom which is 5.0.2 based.
with their RLS3 release they've noted: "NOTICE: This ROM no longer flashes a kernel! This means it uses the kernel that is already loaded on your device. If you flashed a 5.1.1 ROM and are planning on flashing RLS3, you MUST also flash a 5.0.2 kernel.".
1. Is there kernel I could use from glewarne (not allowed to post links yet )?
2. is even possible or a good idea to install a 5.0.2 custom ROM (in my case axis) while I'm already on 5.1.1?
3. if the answer is yes would this be the procedure: install AXIS ROM in TWRP, install 5.0.2. Kernel in TWRP, REBOOT? or do I have to downgrade bootloader, modem etc.?
Please help and excuse me for being a noob
Come on guys. Didn't realize my question was that stupid anything??
It won't work. A 5.0.2 ROM needs a 5.0.2 bootloader. And atm downgrading the bootloader is a no-go.
Thanks!

ROOT and TWRP for Galaxy S6-920F 6.0.1?

I am currently on 5.1.1 stock with rooted and twrp installed. After flashing 6.0.1 official ROM via Odin will I retain ROOT and TWRP?
If not then how can i get rooted and twrp installed?
Thanks in advance.

Do so at your own risk.. flashing official firmware will wipe root.

Rooted S6 G920F rooted on 5.1.1, upgrade to 6.0.1

Hey hoping someone can just help answer my question on flashing my phone.
Currently I have a rooted G920F S6 running 5.1.1.
What I want is a bloatware free minimalistic ROM, so I chose to install is XtreStoLite 3.3.1 FINAL Marshmallow Android 6.0.1,
Do I have to update the firmware first? I tried with Samsung smart share but it freezes everytime I try to use the program.
Any help be great
Is your current software version an official Samsung one? For android 6.0.1 you need a custom kernel for your S6. Find one that supports the 6.0.1 bootloader and then a custom recovery like TWRP.

Hey mazwi thanks for the reply. Yes it's the official stock one running 5.1.1.
Phone is rooted and twrp installed I just wanted to be sure I could install the rom straight away without anything else.
Any advice on this kernel be glad great help?
To flash successful a 6.0.1 rom
First you need to flash modem and bootloader that are compatible with MM using odin.

Second make a factory reset
Third flash the rom
Fourth Enjoy your new rom
As for the kernel it will work 100% with the stock but arter's kernel in my opinion is the best.
*flash the kernel after the rom
*links are from XtreStoLite DeoMod Edition 3.3.1 MM thread

Stuck on 5.1.1

I'm a rooted 5.1.1 J700M user with TWRP and basically I can't run any ROM i see in this forum, everything needs Marshmallow, those godly A5 ROMs which improve speed need MM too.
I tried going back to Stock Recovery and Firmware with Odin but failed, tried another thing by converting the zImage or recovery to a flashable with Odin too and failed again.
I'm a Lollipop 5.1.1 user how can go to 6.0.1, the update isnt even showing on the System Update, so i guess i must use a PC.
Please help on upgrading my rooted 5.1.1 TWRP J700M to Marshmallow
Go to www.updato.com and get an MM rom for your fon and region.
Flash with Odin.

I think you can flash this https://forum.xda-developers.com/galaxy-j7/development/rom-resurrection-remix-mm-5-7-0-t3414185 and then flash ROMS that require Android 6.0 , As it is saying that to install Resurection remix, it may be with Android LP, or MM,

Oreo Custom ROMs on Canadian W8 variant - Anyone successful?

Given that the Oreo S7 update has now been delayed, I've been trying to flash a variety of the custom BTU and Note 8 ported ROMs on my Canadian W8 variant. Every single one I've tried will put me into a bootloop or hang at the S7 logo. I feel like I must be doing something wrong and would appreciate any help if possible.
I'm currently using the Superman Nougat ROM v2.5.0
I've tried the following steps:
Doing a full wipe - Reboot to TWRP - Wiping everything except SD - Reboot to TWRP
Installing each ROM either using AROMA or flashing no-verity-opt-encrypt-6.0.zip then installing the zip for the ROM and/or flashing Magisk-v16.4(1642) and/or SuperSUv2.82
I've chosen both updating the bootloader and modem and NOT updating the bootloader and modem, but no difference. I've tried all different combinations above and I've tried flashing stock via ODIN beforehand.
If anyone has had any success with flashing any of the Oreo ROMS out there on the W8, please let me know which ROM you are using and what steps you've taken to flash successfully. It would be greatly appreciated!
Thanks so much!
Updates?
I am running W8 on Alex DevBase ROM 5.8 (WAS running)
I Odin flashed back to Oreo stock tho recently.
Best of luck.
You need to update to oreo with odin first
Just flash stock oreo, install twrp.
After that you gonna be able to use oreo rom.
I'm on superman 3.0.1 right now.
I'm using Resurrection Remix on the W8 S7 right now.

I did flash stock Oreo via Odin (lost root)
I CAN flash TWRP but getting root is where I run into problems. What am I doing wrong?
I did find that Dev OP from Superman posted an updated TWRP specific for Oreo S7 maybe I should try that one?
