I installed Superman Oreo rom and want to go back to the Nougat version, I wiped the phone and flashed Nougat but it just got stuck in a boot loop.It seems the bootloader was updated to version 3 and nougat uses version 2.Does anyone know how I can fix this? I tried flashing the bootloader and modem through Odin but it gives an error.
I want to do the same. Superman 3.10 oreo to nougat 2.90
Have I to downgrade the bootloader?
Thanks for answer

I tried everything i could find and nothing worked i just stuck with 3.10
Try flash first Stock ROM Nougat than Superman 2.90 ;]
I had Oreo Stock and back to Nougat Stock without problems.
Superman 2.90 could need Nougat Stock ROM
Same here.
Was using SuperMan 3.1.0 but was disappointed with Oreo.
installed stock Nougat ROM via odin 3.13, then TWRP and root, nxt SuperMan 2.9.0.
need time and patience.
Make sure your battery is fully charged. and you have stock latest NOUGAT ROM with adequate AP,BL,CP,CSC.
If you have FAIL at 1st attempt, do it again.
I had 2 FAILs before it PASSED.
Tip:
When your Odin process will FAIL, but process isnt finished yet, disconnect phone from laptop and turn off holding power button, Phone will restart into DL mode with big triangle on it saying to use SmartSwitch for PC to recover the OS.
turn it of again and when screen is off but before the vibra, press and hold PWR+Vol DWN+Home, phone will go into normal DLmode, connect then into laptop and press Vol UP to confirm Odin Mode in Download Mode.
Then using Odin, install OEM Nougat OS.
This is the method that worked for me and had successfully installed Nougat.
After that, boot the system, unlock the Dev options in setting and turn on OEM unlock before you go for TWRP and root.
hope it will help.
Goodluck.

Hope this helps:
Go back to Oreo or whatever ROM you can use
Goto settings > developer options
Enable OEM unlock
Now try flashing nougat if you stuck on bootloop then install a custom ROM that is nougat, then try to flash stock nougat. If it still doesn't work there is nothing I can do use a custom nougat ROM. I recommend ultimate nougat

So is there any method to downgrade the ****ing bootloader?
Mine is ver.3 and need to flash ver.2.
I realy not want to stuck on Oreo. Oreo realy have no Benefits.
There is no way to downgrade the bootloader. Samsung blocked bootloader downgrades starting with the S3.
But why cant we just install the nougat bootloader and modem as .zip from twrp if we are on an Oreo rom?
Is this not possible?

Hello, I currently have a G920T that had been working alright for quite some time. The problem is that yesterday while using it normally, it suddenly froze. Thought it was the app, but saw it was the phone itself. Thus, I decide to turn it on again. When I do that, the phone does not continue after the logo and has the LED light white, while blinking on an off. When I manage to enter the Android Recovery menu it gives me the error shown in the title. The phone's rooted and was unlocked, so I could use it with AT&T.
I attempted doing a full reset, upgraded it to Nougat, and I am still stuck. Any help's appreciated in advanced.
Would like to say, when I installed the official Nougat Upgrade for my phone, upon starting, it began installing some things and then preceded to start Deleting. Afterwards, it just froze again. Did I do something wrong?
To get past this issue you have to Root with SuperSU, this will patch the Kernel to disable DM-Verity and will allow you to boot normally.
If you don't want to get rooted then reflash stock firmware via odin. never do OTA updates as i have always say the come "Dirty"
EDIT: Sorry didn't read you were rooted, just re-root again with SuperSU (To get your Kernel patched again) for DM-Verity

So I use (what I previously used) cf-autoroot again? I ask this, since it seems their website have the recovery for marshmallow version and not for nougat (if I am not able to downgrade to 6).

Root with TWRP and superSU zip, i don't recommend CF-AutoRoot
Before flashing the Zip do the following on a Terminal in TWRP
Mount o- bind /dev/urandom /dev/random

You can use CF-AutoRoot for 6.0.1 and 7.0.

When I use CF-Autoroot and attempt to boot it into recovery I get the following message, "recovery is not seandroid enforcing".
So I'd take I try installing a custom ROM first before attempting to start it in recovery?

Oh, that means CF-AutoRoot has not updated to work on 6.0 & 7.0 bootloader for G920T (It is updated and working on 6.0.1 & 7.0 for G920F)
Flash the stock ROM again. After that, flash TWRP and than flash latest SuperSU zip via TWRP.

I tried doing that, but wouldn't get past the main ROM's screen. I tried a custom ROM then (I think nemesis or such) and lasted longer, but again froze and loops with the white LED light on.
Any suggestions?
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.

Hey guys,
Hopefully someone can help me with my problem. So i did the following:
To get rid of the 7 day Block of oem-unlocking on my s8+ i downgraded back to Nougat. From here on I flashed TWRP + rooted my device with magisk. After That i flashed the RENOVATE_ICE_G95X-7.5 rom + the Flashable_G95xF_FD_Firmware_TWRP_AQL5_r8 Firmware. I've let my Phone start up and went back to TWRP To Update the rom to RENOVATE_ICE_G95X-10.1. To this point everything Worked fine, the Phone Boots completely fine. Now to my problem: im Sitting on the actual stable rom but with the Baseband-version of Nougat which is AQL5. When i try to Flash the actual Firmware (CRC7 or CRD7) via TWRP my Phone gets stuck on the first Samsung Logo and Shows the following red Message: "Only official released binaries are allowed to be flashed". I would be glad for any help.
If you can find a standalone modem file from the ROM you mentioned you should be able to flash it in TWRP recovery. Last time I did this was on a Note 3. I think that the process should be the same with S8.
Can't seem to find one, but i found out that the same error occurs when installing other custom-roms like the King Oreo Rom which installs the newest Bootloader and Modem via Aroma installer. Only solution after that is to Flash Nougat again via Odin.
Hi all
Currently on Batman V2.0.0 Oreo - S8+ SM-G955F
Reason for change is due to poor battery life and intermittent fingerprint scanner.
I have downloaded stock Nougat 7.0 - G955FXXU1AQF7_G955FOXM1AQF7_BTU, flashed this via Odin and everything booted up fine. The next step was to root and device and install twrp.
1. Downloaded TWRP and installed
2. Installed dm-verity and force encryption disabler
3. flashed Magisk.zip
had full access to twrp and had root.
Now i am trying to flash batman V1.50 via twrp. The installation goes fine, when rebooted it stays on the Samsung screen. it will not let me load a OS. The system states no OS installed. i have tried with 2 other Nougat roms and still no joy, i even flashed the correct bootloader and modem and still hangs on logo. is there something i am missing here? all your help would be appreciated. Oreo update is not for me.
Restored a twrp backup to go back to my working version of batman oero again, stuck with this until a solution
just a update, managed to sort it out, all working with Nougat and it is stable

How ?
hello everyone,
i have S8+ with android 7 installed, not rooted and still didnt get any OTA for either oreo or Pie, so i decided to do it manually but i wanna make sure of the steps since it's been a while for me not flashing anything.
first thing i should know is that this update is going to wipe my phone due to the bootloader update
and about that bootloader update, should i flash pie bootloader first or just flash a stock ROM with odin that includes bootloader file ?
any help with this issue is much appreciated

If you are going to update with Odin flash full firmware. ( 4 files )
As for wiping your phone when you unzip the downloaded firmware there will be 2 CSC files.
CSC - Clean install will wipe your data ( same as factory reset )
Home CSC - Dirty install should keep your data
Always do a backup before doing anything.
Note: Make sure after you upgrade your firmware to update your apps so that they will be comparable with new firmware.
