Will this help me get a custom rom with root

If I understood correctly, this process will allow me to flash unofficial images/custom roms etc. I have a s8 with bootloader revision 6 but on android pie. Will I be able to get a custom rom with root after this process? If so can you please link me one?
[Samsung Galaxy S8 Guides, News, & Discussion] jrkruse:
Didn’t realize we were on v8 bootloader. Are you sure of that because latest firmware is only v6

[Samsung Galaxy S8 Guides, News, & Discussion] pixlone:
Bootloader revision 8? Afaik, bootloader 6 is the latest version released on the G950U/U1.

You can install somewhat custom ROMs as long as they don't break dm-verity (i.e. no root) but you can downgrade to rooted Nougat.

Everything you need should be in the first two posts.

Any of them. It don't matter. The slots in odin are more for looks. I have flashed csc in AP and cp pick one and run with it. Usually I choose ap or bl. The firmware knows where it needs to go

or can i use older ap cp files from bl4 or bl5 along with current bl6
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
I don't recommend using zero until you know edl works. It can leave you in a hard bricked state.

You can use older rev ap files. I don't know if cp are incremental

I gots a major issue. I have one s8. Dm verify failed unable to boot. So if I used button combo download mode does not detect. So I flashed combo. Now I'm stuck on first boot screen. I was able to boot to stock recovery. Then I could reboot to bootloader and download mode and it worked Now I cannot even reboot to recovery. So I'm stuck with no download mode. Eliwiggy said you know the pinout for edl. Can you help? Ive got a true hardbrick on my hands. Every ones like test point to edl but then they don't know where they are.

Download mode boots. But does not show added or anything in device manager. No recovery no boot

Download mode was rebooting itself before I flashed combo with no detection unless I did the recovery reboot to bootloader

Just stopping by to say thank you for keeping the snap S8 alive. I upgraded to V6 from your V5 DSC5 U1 rom (originally a sprint G950U) without any issue. Was just curious to know if native call recording or any type of system wide ad blocker is still possible on V6 like it was on the older roms

Edit- I figured out how to enable Call recording.
[Samsung Galaxy S8 Guides, News, & Discussion] Kordeyne:
thank you so much, quick question

thank you so much for this, I was able to use the instructions to load the rooted nougat rom onto my s8.

I used the method of replacing the system.img in your EDL files with the one extracted from the rooted rom zip so my phone now only has the rooted nougat rom.

im new to all this and even though i have searched some I cannot seem to find an answer to my question, maybe someone on here can help.

in the twrp safestrap that I can boot to now, i see that there are 4 additional rom slots that i can use to partition my internal storage aside from the stock room (my stock rom is the rooted nougat)

does that mean that i can split my internal storage and flash a completely different rom to another slot (like a unrooted pie rom) and then use safestrap to change which rom is active and so be able to boot to whichever system i want?

if it can work like this, can someone point me to a guide for it, or write a few line?

i tried to do it but i think i ended up flashing over my stock rom and the phone stopped booting so i had to repeat the whole instructions again to get it working again (i did though)

is it as simple as loading a rom zip to internal storage, formatting a new slot, making it active, then selecting install zip in the safestrap and installing the rom zip?

also does anyone know a good clean pie rom? preferably with stock android not Samsung version (like a pixle)

thank you all for your time!

[Samsung Galaxy S8 Guides, News, & Discussion] sleepysy:
I guess you didn't know what the BL does. The downloader is part of the bootloader, so if you zero it out, you lose the download feature. It's why JRKRUSE posted so many disclaimers and warnings for it.

Option C wasn't meant to be an option if you couldn't get A/B to work. It was an option for ease, for those users who knew what they were doing, and have done EDL methods before on that phone/computer before.

You zeroed out the bootloader which completely wiped it, preventing Odin from being used. If you had enough experience flashing, you'd know all the details already. Or, had you read the previous comments in the thread prior to starting, which is always a super smart move as you see all the issues other have had, including others that were also to blame, then you would have known this prior. Even had you completely ignored all the warnings JRKRUSE provided next to the file link. So, the problem was created by yourself entirely, and have no one else to blame.

. Luckily, you can buy motherboards relatively cheaply on Ebay, since people ditch the phone once they find out the cost of a new screen. So, you can easily get them for $65‐$75 on Ebay, and relatively easy to swap out. In the future, always follow the directions (including warnings/disclaimers & the comments of others.)

"Make Your Own System Image" clarification required ...

If I understand the intent correctly, the "Make Your Own System Image" process results in an image file that can be installed using "G950U_recovery.bat" (basically an update to a more recent version).

I don't understand the last step ... it seems a little mangled:

"5. Reboot to download flash proper bootloaders to match your rom. You may need to make your own"

I'm at the point where I've flashed a new system.img & the G_950_PIE_ROM_CREATE.zip.

(The new image has not been run at this point, & no updated CSC flashed).

Do I dump the updated system.img using TWRP & to use with "G950U_recovery.bat" ?

What BL & CSC do I use to get into & out of Safestrap?

Any insight would be appreciated ...

BTW, both the rooted version & the Safestrap recovery version work great!

I've managed to edit the telephony.db to "customize" my APNs & have deleted bloatware & some carrier apps that run background services (spyware?) by editing the TWRP backups of the system & data partitions.

It's not like being rooted, but there's lots you can do with editing backups.

I need to refresh my memory about permissions to understand how far I might be able to go with this.

"Make Your Own System Image" make BL help required ...

I've managed to "make" my own image (using 6DSJ4 img) that successfully reboots into safestrap using the provided ENG bootloader.

(The instructions didn't mention that it was necessary to chmod the image file to 755 before flashing.)

Now, I'm stuck at making an updated bootloader based on "BL_G950USQU6DSG7.tar.md5" using the "6SDJ4" files to boot into the system.

What files need to be replaced?

Has anyone successfully updated from 6DSG7?
[Samsung Galaxy S8 Guides, News, & Discussion] shellhouse4:
Perfect, used post 2 to flash rooted nougat.

Ran into a slight newb issue with forced OTA update after disabling updates in app store and Developer settings. No pm package manager found in TWRP shell, looked in system dir and searched all using find. Ended up deleting update.zip under data/fota (iirc), rebooted, and promptly removed system update packages using titanium backup once able to get back into the OS.
[Samsung Galaxy S8 Guides, News, & Discussion] DejaVuAgain:
Success ...

After some experimentation, I managed to get a fully working Safestrap on G950U1UEU6DSJ4

To make an updated Safestrap bootloader, simply replace the NON-HLOS.bin file in BL_G950USQU6DSG7.tar.md5 with the one from the update BL file.

Rename the new bootloader as required. I didn't bother adding the .md5 to the .tar.

It is necessary to follow the same sequence of flashing the BL & HONE_CSC after running G950U_recovery.bat (which was used to inject Safestrap into the update system image).

After the first boot of the updated system, entering & leaving Safestrap is done by flashing the BL_ENG_BOOTLOADERS_SAFESTRAP_G950U_V6.tar.md5 or the newly made bootloader as required.

So from what I read in this complete thread is no way possible to have a system-less root, so any ideas on how to unroot safely after I modded the phone ?? I have apps that check for root and will not work if rooted but I want a lot of the stock rom not stripped down like most of these roms here so I want to mod it myself but it looks like these roms are not easy to unroot and not sure if I root a stock rom if I can unroot.

Is there still no root method for pie. Because I was going to use sampwnd root method and I know how to do everything required. I dont know if it wont flash the 4odin files because I am on a newer boot loader or what. I am on G955USQS6DSJ1. And again. I am wanting to know what if anything I'd have to do to root using the sampwnd method without having to go back to oreo. Or just why it isnt letting me flash the sampwnd odin files. It starts and gets to the .abl then fails.

Speaking of rev. 7 BL, I was planning on retiring my S8 (VZW) so I purposely flashed the latest stock firmware after being on a rooted nougat.

Any ideas how to get the phone to boot would be greatly appreciated. I've wiped cache and data in recovery, but that didn't help. Also, if it means anything, I also fail dm-verity after flashing full stock. Thanks again if anyone can help!

The stock combo boots just fine, but after data wipe, odin flash full stock (minus userdata), added PIT, and checked nand erase, I get successful verity hash tree until I reboot to system.

I don't know if it's a clue or not, but notice the bottom of the screen in the attached pic. Failed to mount /data and the mismattached carrier ID.
