[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] elliwigy:
lets be clear, it does not "completely remove" green screen issues.. some including myself have still experienced some screen issues even on AQI1 firmware.... all you are doing is flashing latest combo boot.img per his guide, it is not in any way endorsed as a SamPWND "fix".. many "fixes" are not possible until we can use modified boot images or stock boot images which means an unlocked bootloader or secure boot disabled.

and as i stated multiple times, its simply updated combo firm files.. thecombo firm files used in sampwn and that are required while rooting include abl, devcfg, boot and recovery images.. so if you are updating the boot.img, its highly recommended you update all 4 of these images.. if not you will have firmware from 3 different roms and can cause issues..

if you follow guides from other threads and run across issues pleasedirect yourissues to that thread and not in here.. this isstrictly a root thread

Also, if you see a thread not created by one of us listed in OP as contributors, then it is not anything made by one of us so we cannot support or answer questions about those threads.. basically dont sendme pms about a green screen fix or a battery fix if i didnt create the thread meaning i do not support it..

i am saying this now bcuz threads are starting to pop up saying [SamPWND] in the title that we are not affiliated with at all and getting pms about them.. any official "fixes" will be added to op when they arise but so far:

1) no unlocked bl or secureboot bypass meaning no modified boot.img

2) No screen issues fix (some might have less issues updating combo firm files, this is always recommended, nothing new to be on latest possible without incrementing bootloader)

3) no battery fix (some posted but dont believe anyone actually successfully tested it meaning it didnt work. 80% is baked into the boot.img so this along with screen issues are not fixed)

4) stock boot cannot be used due to dm verity, it cannot verify the system.img when modified/rooted.. the combo boot works since it has dm verity disabled and is permissive.. the boot.img only verifies the system img.. the bootloader verifies the boot.img so this is why we cannot use a modified boot.img but can use a rooted system.img.

5) files from combo firm used include: abl.elf, devcfg, boot.img and recovery.img.. IT IS OK TO FLASH THESE USING ODIN/COMSEY ODIN

6)Besides the rooted system img and the 4 files from combo firm, everything else u flash can be from stock firmware such as persist, modem, xbl.elf, csc etc etc

I am not planning to post updated files as thatd be a huge task since newfirmwares come out all the time as well as u have the U, U1, W etc variants so beyond the sampwnd files and rooting is outside the context of this thread, u are freeto use w.esystem img or co.bo files you choose
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
Well sorry just assumed it was since i cant see them anymore on the app but thanks for the clarification
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Goliath27:
First and foremost, THANK YOU ALL!!!!!!

Now, it's been a couple of years and I have not kept up with the whole root game. My only reason for wanting to Root would be to find a snapchat app that does what Snap Prefs did. But, I have no idea if I need root, or something else? Is Magisk an option?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] elliwigy:
u need to read.. magisk has been discussed multiple times in multiple threads and most includes info on it in the OP

YOU CANNNOT USE MAGISK

unless you have unlocked the bootloader magisk IS NOT POSSIBLE

ppl dont understand how magisk even works lol.. it MODIFIES THE BOOT.IMG which we CANNOT DO
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jaischaamu:
After the part 2.. i got an error saying " security error your phone has been flashed with unauthorized software .. etc " any way to bypass this to get full root access
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Deliz8806:
There is a solution to this somewhere in this 90 page thread lol I remember coming across it do some more digging and good luck. I believe it's a user error an option in flashfire left checked or unchecked or maybe with the order of flash, wipe, etc but anyways you'll find it somewhere in here
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jaischaamu:
ok. Thanks in advance .. will check
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] davidisflash:
Is USB processing working for you on Viper, bro? I only can get it working if I set FX mode to compatible and force a profile such as headset. This then breaks YouTube audio, alarms ,etc, and still, Viper sounds bad.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jiffyjeffsd:
I got the same error. I was following the instructions from the root junky video.

I was using an old super su zip.

Use the files from the op.

After that,no problem.

SamMobile's regular servers are on maintenance so I can't download the latest G950USQU1AQGL update from here:

https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U/VZW/download/G950USQU1AQGL/186122/

Can someone please mirror and upload the latest firmware update so that we can extract the ext4 and update to latest firmware with FlashFire?

http://updato.com/firmware-archive-select-model
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:
updato (as the above comment mentioned) has it and also if you search Google for the entire firmware version (G950USQU1AQGL in this case) you can usually find tons of places that have it available for download.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] davidisflash:
Updato worked. I had searched for that string before posting my question in Google, and other sites either redirected to SamMobile or seemed not so legit. Didn't want to potentially get a tampered image.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:
Yeah I should have also said use your best judgement when it comes to finding a place.

Oh yeah, do they have it on chainfire's new firmware.mobi site?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] davidisflash:
Haven't checked
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:
He sure does: https://desktop.firmware.mobi/device:466

This is the new best place for firmware because:

- its chainfire

- no silly download caps to ploy you to subscribe (I'm guessing)

- not relevant to us, but you can download them auto rooted w/ CF autoroot

- its chainfire!
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] elliwigy:
i have to agree with u on this one.. the site is awesome lol.. thecf auto root thing is amazing too, u can basically customize your own cf auto root.. now we just need to unlock our BL!
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Aruku:
I'm going to repeat the whole process to update to the latest version, maybe that will help with my SD problem; does anybody know the difference between the CSCs BST, GSF, USC, XAA and XAS?

I just noticed that there is no AT&T U firmware, just U1. Wasn't the U1 the unbranded one and the U the ones with the carrier bloatware?

https://www.sammobile.com/firmwares/galaxy-s8/sm-g950u1/

https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U/

I understand less and less every minute about Samsung's firmware nomenclature... @_@

What benefit do you get from flashing CP and CSC after the fact? Can't you have VoLTE without doing it?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Aruku:
[please remove]
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jhofseth:
CP has modem and CSC is carrier specific code; I've had no issues with SamPWND root on latest T-Mobile system.img.ext4 and latest T-Mobile CP + CSC. T-Mobile is my carrier.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] insaneshan3:
could someone please help me with this? I did everything up to the setsid su part and i even got it to exit

but for the life of me i can't get the next step. I've tried over 15 times, it wont mount rw. system is always mounted as ro.

I even disabled security log agent with an app i purchased from the store but no dice. Any input / advice is much appreciated.

Thanks!!
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] freak69ize:
I had to reroot the other day and was having the same problem. Took me 2 hours to finally get it.. Just gotta keep trying
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] insaneshan3:
Thanks for the reply, just to clarify did you just flash the same files over or did you flash the stock back and then try it again?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] freak69ize:
I did something stupid that put me in a boot loop.. so odined the root fw selecting nand erase. But when i got booted up into the sampwnd fw and started root process is where i had problems getting system rw.. it kept coming up ro. It took awhile but finally came up rw.. just have to keep at it. Remember your in a unstable root shell.. sometimes it goes the first time.. sometimes you gotta take a few wacks at it. lol
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] eelsid:
Don't use unstable shell. Use "adb shell setsid su" as described in the S8+ instructions. [MENTION=8034635]TimelessPWN[/MENTION] please update OP as unstable shell is unnecessary.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] AngelRyu:
Ok I'm so excited and thankful for ALL of the devs hard work and long hours and not giving up!!!

So I never ever updated my phone until four hope ? of a root to come about so, my question is, will this work on the latest firmware of the s8+ or should I keep it on the old one im on(7.0) ? Just want to know if I can update to latest and still achieve root. Thanks!
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
Only things different on updated fw is if you havent gotten the bixby update to not remap it (but now you can disable it through bixby app update), and monthly security patches. You should be fine with rooting the phone if you do it properly. Good luck.

So took a nap and left my phone on the charger... I woke up to it at 81%
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] elliwigy:
what he means is in my instructionsand provided adb you do not need to press enter many timesas the first adb command will drop u right into a stable root shell, no need at all to hassle with stability to gain a root shell

whats your point?

ppl have experienced this randomly and even with higher than 81%

if you know what caused it then by all means please share lol

Thanks but VZW is probably Verizon don't think it will work for Boost.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:
It will be in the original firmware worst case. Download the latest US from somewhere, try sammobile or updato I'm not sure is firmware.mobi keeps these files. It should be inside the USERDATA tar you will have to look up how to mount the image file on windows I don't know how as I don't use Windows. If it's not in there then there is probably a userdata.img.ext4 (same name in the USERDATA tar) inside the AP tar. It will be in one of the two as otherwise it would have to be a system app which means it wouldn't be upgradable

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] highaltitude:
I've had 83% on mine before.

It is kind of funny, we can get root but can't find out why the phone reads only 80 for max battery charge
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] sparky2029:
Everytime I flash it, everything is the same after it reboots. I don't ever see the viper app get installed. Do you have the zip that you used to flash by any chance?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Nysarea:
Odin files to the pc. The gm950u files are what you need. Im on xfinity mobile but got tricked into flashing the system image file from cricket because I mistakenly found some info that suggested the carrier code for xfinity was CCT. Turns out it was crickets... So yeah. Haven't bothered to try the process again with xfinity firmware that I haven't bothered to look for yet. Got it rooted and has been mildly glitchy with modem crashes rarely when my signal is low while traveling but otherwise fine. Can't wait for a %80 battery issue fix.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] yungrandy:
ok so im safe to root with this process? And thanks for the response. oh and i should back up my phone first right ?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Nysarea:
Yep xfinity mobile S8 is safe to root with this process.

If you can backup then of course do so :)
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Aruku:
So I'm back in stock, and while it sucks not having root to restore my TB stuff, I can use my SD.

The whole process confirmed what people seemed to already know in the S8+ thread: with this root method, we can't use certain SD cards, maybe just SDHC/SDXC.

I also discovered that the AT&T bloatware comes with the eng firmware, not the U1 I downloaded, so something else I learned.

Does anybody know why the "Phone bootloader update" option in Odin is greyed out? I've seen it like that several times, but then after the first flash this time it started to be usable,

without doing anything different... Maybe because I selected a home CSC?

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] sawixso81:
just a thought I havent looked into it as I just got my s8 yesterday coming from a note 4 and love it by the way, but when i was working with custom roms in the past for example i was running a note 7 port on the note 4 and would unplug the phone from a full charge and it would drop instantly to say like 95% well looking into the framework.apk file the power profile was set for the note 7(might have been an s7 rom) for a 3000mha battery instead of the 3220 mha that the phone had, even the battery stats app showed the phone having a 3000mha phone so i corrected the power profile to show the proper mha battery and now the phone shows proper charge.

Not sure if this firmware we use to flash has a different power profile than what the tmobile phone is?

Once again just a thought:good::highfive::good:

by the way did I say this phone is the s@#$lol

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Nysarea:
Yeah mine did the dump files thing too. It has something to do with the sampwnd firmware. It's temporary. Just ignore it. If you don't know where adb is just get the new copy from the op and use that one. The rsa keys is the prompt the phone will give you once you initiate adb connection. Disclaimer also: I am not a pro with this. I stumbled through just like you seem to be. Just follow the instructions in the op and check out the YouTube video some guy did for this process.

How is this root method better than CF auto root?

How is this root method better than CF auto root using odin to flash a rooted kernel?

https://autoroot.chainfire.eu
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] elliwigy:
lmao seriously?

co sidering that cf auto root isnot even possible on alocked bootloader this is the ONLY rootmethod available.. so its this method or no method atall

if there was multiple options, this method doesnt trip knox like cf auto root would either
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] falcon67:
I think if this method does not trip KNOX then this is a big advantage. However I am asking because CF Auto root website lists both G950U and G955U rooted kernels to flash via odin.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] elliwigy:
they are auto generated.. it also clearly says they will not work on devices with locked bootloader.

i can go to his new site and build a custom cf auto root for my g955u but since our bl is locked it will not at all work

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Nysarea:
OK so run me through what exactly you have done so far. You've odin'd the sampwnd files and got the phone to boot after that, right? Then you connected your phone to the computer with USB debugging enabled and have the Samsung drivers for the phone already installed right?

---------- Post added at 04:29 AM ---------- Previous post was at 04:23 AM ----------

When i did it I followed that YouTube video I linked and just followed his instructions with his tool from the downloads in the video description. I was pretty sure the RSA keys thing was about the phone asking to if you want to trust the pc that you have it connected to and to hit yes.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] yungrandy:
yes i had usb debugging on from beginning but after it rebooted it kept saying that it cant access the data on my phone and to install samsung smart switch or android file transfer

---------- Post added at 03:49 AM ---------- Previous post was at 03:41 AM ----------

does adb have to be open or somthing on pc for it to do anything or ...?

---------- Post added at 03:53 AM ---------- Previous post was at 03:49 AM ----------

cause i never got the window to pop up asking to allow adb
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Nysarea:
Hmm it did something like that to me when I tried the process without rebooting my computer after installing the Samsung drivers. I had to factory reset it like 4 times before I realized. But it was odin failing on the first part for me. If you got past the flashing of the sampwnd files and it booted ok after that is when i ran the autoscriptor from the rootjunky youtube video. Just watch that video is about all I can offer at this point...

And yes, after you've rebooted and plugged the phone into the pc, running the command window from the adb folder is when the prompt to allow the phone to trust the pc comes up.

And ignore the smart switch message. You are looking for the other prompt (trust this pc)
