Updating bootloader and modem to the Oreo and then go back to the Nougat - Samsung Galaxy S7 Edge Questions and Answers

Hello there!
I come here with really important question.
I use the Android Nougat as a daily driver but I'd like to update system to the Oreo. Will I be able to go back to the Nougat if I flashed the Oreo's bootloader and modem?
Thanks in advance for answers!

If u updated bootloader there is no way back

Can you explain how did you do that?

I'm confused for now. Can anybody tell a little more about this? Is it possible via TWRP? Or neither via TWRP nor Odin??

Nope. Works for OS3 too. I believe the firmware is what's causing your bootloops. give it a shot.

I understand you want PA, but your firmware needs to be MM firmware. So you can either flash that or flash the official OS3 first then flash PA.

Is it safe to upgrade to TWRP 3.0.2?

Hi there.
Is anyone here using TWRP 3.x? I'm still on 2.x, since I read of lots of problems with newer versions of the recovery on this device, but I'd like to upgrade now. Can anyone give me some feedback?
Thanks in advance
It works but as with multiple posts not with Aroma.
Sent from my SM-N930F using XDA-Developers mobile app
I see no reason to update if u have no issue on 2.x. sometimes upgrade is just a no go.

Try it.. It totally a new design You can revert back, if you don't like it.. By flashing the image through the new twrp itself.

If you're trying to downgrade, it means that you've flashed TWRP.
If you've flashed TWRP, it means that you already know how to flash a custom recovery.
If you already know how to flash a custom recovery, then this is EXACTLY the same thing. Just pick an older version of TWRP and flash it the exact same way you would flash any version of TWRP.
And if you don't even know how to do that, google is your friend.

I can probably see right now, you've done it wrong... Download stock rom from huawei.consumer... For some reason i thought it's gonna be android MM, but it was android N, so no problem here, just download stock rom and you will have newest android.
You probably downloader rom from xda, rom it's in .zip right? And you tried to flash it with TWRP?

Yesterday I had this issue, it's more easy than it seems. In Revolution Recovery for Nougat, flash the update.app ZIP with 6.0 , it will show you a lot of errors, but don't worry, it's ok. After this flash than DUALSIMOEM.zip and after that shutdown your phone and use the 3 buttons method to automatically ,,update" to B161.

That's because u don t have the bootloader unlocked Also, verify in Developer Options to have Enable OEM on, that's why you have an error in CMD

How to update to PIE official (unlocked Bootloader with TWRP)

Guys today morning I got the OTA UPDATE to PIE. I am currently on v340 with an unlocked bootloader and TWRP already installed.
Should I go with the OTA update? Will it cause any errors?

Stay on oreo, pie is a disappointment over oreo in many ways, like BB reduced, sound quality reduced, no night light and most important you can't play PUBG in HD and many more.
If you really want to taste pie then you can use custom pie roms otherwise stay on stock oreo.

Can I update or not? I don't care if I lose TWRP. I don't play PUBGM. Will it cause any issues as my phone already has TWRP. Can I simply download the OTA and get on with the installation.

If your bootloader is unlocked then it's not a good idea to update via FOTA in my opinion. Wait for until someone made a flashable Twrp zip.

To install any rom using twrp you must download the rom and place it in your storage
Then boot into twrp
Click on install and and browse to your file click on it and flash it...
You can also do clean flash by wiping your sytem and data before flashing....
I saved update file on SD card, restarted mobile and update proces itself started.
Everything was fine.

I think I should wait till someone makes a TWRP flashable zip. Way too much hassle, again going back to stock rom using adb, then updating the rom, then installing Twrp and magisk again.
