Hello,
I wonder if it's possible to flash a marshmallow Rom directly from Oreo with twrp? Is it possible or the boot loader will create some issue?
Thank

bootloader will create an issue. marshmallow is long gone my friend unless you have some older devices that were rooted and had TWRP installed prior to the bootloader upgrade was issued
Ok sad

Hi, i have a xt1621 non plus, i've unlocked for rooting Marshmallow, but now i have the Nougat Stock rom 25.93.14-4 via stock recovery. I've read in other threads that i need the latest stock rom for my device to re-lock the bootloader. I can't find the rom.
Now, when i downgrade to Marshmallow, the update to Nougat 25.93.14-14 appears, but is possible to re-lock with the OTA update?
Regards.

No, you need to flash the images via fastboot and then run the lock command. There are explicit instructions on this forum.

Thanks for the reply, I'll have to wait for the stock rom release. :good:
Hello XDA!
I've rooted my phone (the J5) about a week ago after finally deciding it might just help me to some extent.
Well, then I realized I'm still on Android 6.0 and updating obviously doesn't work.
This brings up multiple questions for me:
Is there any way to get the official update?
OR do I have to download it myself and flash it on?
Can I flash Android 7.1 on it without bricking the phone or losing all data?
Can I flash any firmware (or firmware updates) without losing any data?
If anyone could answer my questions, I'd be grateful.
Thanks in advance.

You can't update your phone OTA whule it's rooted. If you want the new 7.1.1 stock you must flash it manualy over odin. If your phone is on stock 6.0.1 the manual flash will not erase any of your data or apps. If you are on a custom rom then it wil erase data. When you install nougat it will be unrooted and with stock recovery.

I understand that, but will it brick the phone or erase the data? The J5 is certainly not made for Android N.

I've used the CF AutoRoot package for the root. Does CF-AR install a custom ROM?
Thanks for the answers.

What version of the J5 2016 do you have? Only install 7.1.1 manualy on the J510FN.
A custom ROM is a software installed over a custom recovery that is totaly different from the stock rom.

Alright, I've got a J500FN, so the dream of Android N is gone.
I didn't use a custom recovery, I used Samsung's Download mode.
This is it. Thanks for your help, ya'll. I'm gonna upgrade to 6.0.1 manually now.

There is no official Nougat for your device, so don't ever try to install tge J510FN version ?????
But there is a ported stock nougat rom for your device on the J5 2015 ROMs section
hello, is it possible to install the ROM -15, when I already have the -92? When flashing it by fastboot, it does not allow me.
Nope.
How do I know which bootloader do I have? I'm currently running build B35.
Can someone direct me to a thread how to flash universal bootloader and modem?
If I use bkores flash toolkit, it said you have to flash universal bootloader, modem along with Rom and Gapps but in which order?
If using twrp for future flash do I need to flash universal bootloader and modem every time I switch ROM?
I'm not an expert but here's what I understand.
1. You don't have to worry which version you have unless you're flashing a custom ROM, usually for Nougat you want the B15 and for Oreo you want the B35.
2.Universal Bootloader>Modem>ROM>GApps>Magisk/SuperSU
3.You only need to flash it once if you're switching ROMs with the same android version.

If you haven't you need to unlock your bootloader before you can start flashing custom ROM. You can find a guide on how to do it here.
So I really want to install a custom rom and I know I need to unlock the boot loader and flash it with twrp. But I been reading around here and it seems unlocking the bootloader on Oreo is not possible and the only way to do that is to downgrade to nougat... except I don’t really know how to do this on my device since as previously stated, the boot loader is not unlocked and I don’t know where the stock rom for nougat is even available to download from, or any necessary tools to download to be able to do this (I’m a complete noob). Some info of my device: A2017u, Oreo, B20
Help would be appreciated, thank you
I think you may need to go back to Marshmallow to unlock bootloader and install TWRP but I'm not on an A2017U so won't try to advise you.
I did revert my own A2017G from latest Oreo back to Nougat ok. Since gone back to Oreo. It seems to work when stock but once you meddle with it that's when all the problems start.
