Downgrade Android - Samsung Galaxy A8 (2018) Questions & Answers

Hi,
I would like to know if you know how to downgrade the android version of the Glalaxy a8.
As several A8 users, my phone is becoming really slow and I would like to do something about that. I tried to flash Android Nougat and Oreo official stock rom through Odin, but that didn't work. I have been told that Samsung had set in place some procedures to block any downgrading non-approved by Samsung itself. But I am wondering if there is a way for me, maybe by installing TWRP I could be able to install whatever ROM I want ?

How Can I Downgrade Verizon Galalxy S6 from 6.0.1 to 5.0.2?

Hello, due to me having to replace a broken S6 that was running 5.0.2, my new phone was running 5.1.1 by default. When Android M came out, I decided to go ahead and upgrade, hoping for an exploit. However, this hasn't seemed to happen yet. So my question is, since 5.0.2 is the only OS version I know of that can be rooted for my device, is there a way I can downgrade from M to that version? Or is there any other way I can have a rooted phone? I am by no means an expert with this stuff, but any help would be IMMENSELY appreciated.
Unfortunately, no and no. The consensus seems to be that a new root method is unlikely to be found.

Attempting to downgrade at this point will render the phone useless until you flash the version you are on or higher through Odin.

New Rom for my S7

Hey Guys,
i'm owning an Galaxy S7 (G930F) and it's have a Vodafone Brand(Germany), (boot logo and some apps from Vodafone).
I'm really pissed of the update schedule from Samsung, and want a root to, so i decided to install a custom Rom.
But my latest custom rom phone was some years ago ( old Samsung GT 8150 Galaxy W) I think since it have changed many
I want a ROM that have an auto updater, i had that on the old GT 8150, when an update was ready, it was a easy way to install.
Its possible that knox will not be triggered?
Which Version of Rom can i install? I had some issues with my 8150, when i started testing some ROMs, some Roms had the boot bug, and then i tried to install the Stock ROM, but then was no able to boot.
On this time this Infos says me S7.
Android 7.0
Basicbandversion: G930FXXU1DQH6
Build: NRD90M.G930FXXu1DQH6
Knox 2.7.1

Sorry for that bad english,
Thanks and regards,

Custom ROMs require unlocking the bootloader, which triggers knox.
is there a simple way to get root on my S7 then?

Any good ROMs for the Verizon Galaxy S6?

Hi,
After *days* of research, I finally was able to root my Galaxy S6 SM-G920V(erizon) on Android 5.1.1. I was also able to install FlashFire. I'm having trouble finding any custom ROMs though, I tried to flash a stock Oreo ROM but it failed so I had to go through the process of rooting the phone again, which is kinda lengthy and I don't want to have to do each time.
Anyway, if anyone was successful in installing a custom ROM on their Verizon S6, please tell me what ROM you're using so I could check it out.

Need Help Turning My Phone Into A Rubber Ducky!

I would like to turn my Samsung Galaxy S7 (G930F) into a USB rubber ducky. My device is running android 7.0 and it is rooted with Magisk v16.0. I have tried flashing kali nethunter, but it only supports up to android 6.01 for my device. I would flash android 6.01, but i REALLY dont like it, im willing to flash android 8.0 if that helps. TWRP is installed and i also have kali linux installed (with linux deploy). I tried using Dual Boot Patcher to dual boot android 6.0, but it wont boot up whenever i switch to it. Any suggestions for how i can get it to work? I know a bit about the android os, but i am in no way an expert. Any help is appreciated and i am happy to answer any more questions you might have about my device.
To clarify: i do not intend to use this maliciously, i just think it would be cool (and maybe to prank a couple of my friends).

Need help un-rooting my S7

Hi All
I had and still have the latest software for SM-G930F
I followed a tutorial to root my s7 but then realised that root does not work properly on android 8.0.0
I would love some help to un-root my s7.
Baseband version
G930FXXS7ESL5
Build Number
R16NW.G930FXXS7ESL5
I have used odin to re flash original firmware but it still says the device is rooted.
like Samsung pass comes up this device is rooted so this option is unavailable.
i used sm-g930f cf-auto root, magic-disk and no-verify-opt-encrypt 6.1 and have twrp 3.3.1.0-herolte
it will only let me re-flash android 8.0.0 original firmware witch i though would wipe the the phone completely and un-root but i was most certainly wrong.
i wold love my s7 back on android 7.0 or below so that i can have a custom rom installed.
If you need more info let me know and thanks i advance to all the developers, moderators and users.
thanks
John
Hey there, since you have twrp already installed you could look into some of the custom roms if you want theres even Pie roms with OneUi avaliable, i have almost no experience with cf autoroot but if you want to completely get rid of previous system files before flashing the firmware select the option 'nand erase' in odin and make sure you fill every file to its respective field.
I would suggest against using 'plz' 'pls' in the title or your thread because that will most likely get you ignored, feel free to give me an update if that worked for you!
