How to install Oreo ROM?

Hi! I'm really humbly sorry, I'm new to this stuff, so I have to ask you...
I have a Galaxy S8+ Duos (SM-GD955FD). I bricked it once or twice trying to root it. So I had to flash a sammobile.com ROM...
Now this is done, I have a successfully rooted phone with with the Baseband version G955FXU1AQH3 and the irritating "security notice" (since I was not able to install Magisk, and the NotifyClean app doesn't work either).
I would like to flash the latest Oreo and root it. I also heard good things about the Oreo ROM by alexega.
So: I'm on AQH3 rooted. What can I do?
Thank you for your patience.

If wou want to install stock ROM you must follow this instructions: https://forum.xda-developers.com/galaxy-s8+/how-to/guide-how-to-flash-crap-using-odin-t3748555. Bear in mind that if you install stock due to security issues you can't unlock OEM for 7 days after flashing (you must not reboot your phone for 170 hours).
If wou want to flash a custom rom you must have TWRP installed, move the zip rom to your SD card and just flash it from recovery. Make sure to format data before flashing.

Nice, thank you. So I have just flashed the thing with the sammobile.com ROM again (so, no root) and updated to the oroginal firmware Oreo following your link (I worked parallel).
I was just about to root Oreo and was googling for a way... But did I get you right? I should not reboot my phone for 170 hours now?!? So, no rooting until next week?!
Edit: I have developer options enabled and the "OEM unlock" switch is on (it says: "Bootloader is already unlocked.""). So... confusion...

Excuse me, are you currently on Nougat 7.0? If so, you obviously have OEM unlock option available. The problem is in the new 8.0 stock rom, wich sets RMM state to pre-normal preventing you to flash TWRP and to get root in OREO. To skip that you can directly flash a custom rom with 8.0.- Otherwise (stock rom) you must wait 7 days with no phone reboot to get ridd of that pre-normal issue and then flash TWRP and flash Magisk.

Just rooted the new Oreo ROM with TWRP. Works just fine, thank you.
So, what are the advantages of the Oreo ROM by alexega compared to XXU1CRAP?

Do you need a custom rom to not have the RMM lock anymore? A stock with BlackMesa's RMM START .zip is not right?

There's no need to have a custom rom, if you flash the fix in stock RMM lock gets killed everytime.

First you have to install OREO and wait 7 days without reseting your phone. After 170 hours, you get OEM unlock in developer options and you will be able to flasf TWRP. After flashing TWRP you flash RMM-State_Bypass_Mesa and that´s all.

You can download Android 10 manually or you can use the oxygen updater app from the Android market to download the latest stable or beta Android 10. I've rooted and unlocked/relocked my bootloader several times without any problems.

You idiot EMUI 10 cannot be bootloader unlocked, downgrade to EMUI 9.0!!!
If you want android 10 or even 11 you need something called a GSI, which I can inform you about it.

that what i was thinking also, so bye Emui 10 for ever i guess.
what was the rom base on android 11 you are referring to ?

GSI Project treble rom.
The definition is https://source.android.com/setup/bu...tem image (GSI,or higher can run successfully.
Google's Offical GSI will not boot on huaweis though.
After unlock bootloader download this https://github.com/phhusson/treble_...v300.l/system-roar-arm64-aonly-vanilla.img.xz
use 7zip(https://www.7-zip.org/a/7z1900-x64.exe) to extract the file once and rename it to system.img and move to C drive WITHOUT under any folders.
Then go to recovery and factory reset, do not advance wipe, wipe>factory reset only
Then go to fastboot and
fastboot flash system C:\system.img
Failing to follow will result in rage!

Backup System, Vendor, Data and Internal storage in TWRP before doing anything will be a wise choice, in case anything is wrong.

Forgot to mention you must flash magisk in TWRP before installing rom, to disable AVB(Android Vertified Boot) so that a custom rom can be loaded.

Yeah for sur, i'm rolling back, unlocking BL then TWRP in order to get a full backup. I ll check the rom after that
A senior member refer to for EMUI 10 upgrading :
"Don't update system via OTA when phone is rooted or bootloader unlock. Flash firmware via erecovery and rooted again"
i think this is incorrect right ? he cant root again while on EMUI 10 ?

well i'm stuck with twrp not decrypting my data
i managed to install TWRP (several version), boot on them and so nothing to do
also can get root easily and magisk as i sideload zip from crypted TWRP version (worked)
tried the version twrp_clt_0.1.img from XDA stuck on TWRP starting screen
i'm almost giving up

Extract Android 11 Gsi, rename to system.img and move to C drive , not under any folders.
Go to fastboot then
Fastboot erase data
Fastboot erase cache
Fastboot flash system C:\system.img

Question ROM

I'm asking for opinions. What is the difference between ROM 13.0.19.0.SLCEUXM and xiaomi.eu_multi_XM12_V13.0.37.0.SLCCNXM

The first is stock rom intended for the European continent.
The second is a custom rom based on Chinese firmware with many modifications and latest developments.
Better than stock.
See here:https://xiaomi.eu/community/threads/miui-13-stable-release.64441/
Change version to stock rom(EEA to Global,etc) or install Xiaomi EU rom requires bootloader to be unlocked.

It is better to install the first ROM or the second one. Bootloader is unlocked. And I have a second ROM installed. Should I reinstall it? And I have to format in TWRP? Thanks for the answers.

How did you install the rom and what rom do you want install?

I had 13.0.19.0.SLCEUXM there, but I formatted, apparently there is nothing there, the system says that it is not installed. Formatting doesn't work. I can only go to fastboot or TWRP. I do not know what to do. I would like to install such a ROM there, from which it will be possible to upgrade Android 13 when it is available. I don't know what to do. Thanks for the help.

For a stock rom I always use MIFLASH
Use Miflash:
https://forum.xda-developers.com/t/flash-tool-guide-use-xiaomi-flash-tool.4262425/
DONT RELOCK THE BOOTLOADER
EDIT:
With a stock rom and a bootloader unlocking the play will not be certified.
This problem does not exist with XIAOMI EU ROMS.
Important:
What's the version of your phone?Global,EEA,CHINESE?

Global

Benoni1 said:
Global

So,if you use Miflash you can re lock the bootloader.

I like to use TWRP, Magisk so I don't want to lock the bootloader. I need to learn how to do with MiFlash. I was able to install the rom via TWRP. But I had big problems with formatting the data. It seems to be fine now.

You want to be up to date with the latest rom so why did you install an EEA rom when there is a stable global beta in A13.
https://xiaomifirmwareupdater.com/miui/cupid/
You have problems with the TWRP and you want to root and use modules, if you are a beginner these are not really things to do, with the root an error and the phone is broken.
Prevention is better than cure.

oneplus 8t unroot + get back to stock

Hi,
I am currently on A11 with Oneplus 8T and unlocked bootloader + rooted stock rom.
What is the proper process to lock the bootloader and to get back the stock rom? What are the options?
Can I just factory reset the device?
Thanks,

You're confusing us
You're already unlock+root
Then again ask for unlock BL!
If you want just stock then flash boot from stock that's it nothing else to do

@Mr Hassan sorry, I have just edited the first post. I want to LOCK the bootloader and get fully back to an unrooted stock rom.

Install the latest rom for your phone from the OnePlus support site using local install. That will overwrite the Magisk patched boot you currently have installed.
After the phone reboots (you'll see that Magisk shows it's not installed) then boot into bootloader and use fastboot oem lock
Then select NO (yes, this is a bug in the OOS bootloader) and that should wipe your phone and bring it up with the bootloader locked.

if you want the easiest fastest way, just use the msm tool for the correct model.
ps. if you dont care about losing your data
