FINALLY!

We Present To You

SamPWND!

Root for the USA Variants of the S8 & S8 Plus Devices!
(This thread will focus only on the S8+)


This thread had been closed/locked until further notice. The thread and links should remain active and the thread has served it's purpose. You will need to search the thread if you have any questions pertaining to root or any errors/issues that you are facing. The other reason I have decided to close the thread is because it has gone off topic one too many times, people like to argue and debate and MODS have had to come in here 1 too many times to clean it up so as to make life easier, I will just shut it down. Please do not bombard me with PM's for root assistance because if it has been answered in this thread already (and it most likely has) I will just direct you to search in the thread if I am able to respond at all.

ALSO, please do not utilize our firmware/root files/method without gaining permission first or I will ask for the thread to be removed/locked. Just because the thread gets closed does not mean we didn't spend a lot of time to get to this point.

Thank you and enjoy SamPWND root!

DISCLAIMER:
We are not responsible for any damage done to your device as no one is "forcing" you to root your phone! If you are not sure of how to follow instructions or use ADB then I would suggest waiting for someone to help you or that you read up on how these things work before diving head first. The ENG system is not very stable when it comes to root as well as it has a ton of tools and binaries not available on stock devices so we are not responsible if you break something while on any firmwares but especially while on the ENG firmware.


DISCLAIMER 2:

Please do not take our work and post it elsewhere. We spent a lot of time on this for people to take it and use it as if it is their own. With that being said, if you have a better process for something or find any issues/errors, please PM myself or one of the listed contributors of this root method, do NOT post it directly in the thread because it causes confusion. We know with 100% certainty the files and method presented WORK. If it is not working for someone there are a number of possible reasons why. If users start modifying our files/scripts and posting them and you decide you are going to use someone else's files/scripts, do not post in our threads asking for us to help you because we will have no idea what was modified or changed and will just tell you to use the original files.


Returning to Stock:
- It is possible to return to 100% stock and it is very EASY to do.
- This is the reason why I provide both Normal, and Comsey ODIN's.
- All you need is a full stock 4 files firmware of your choice.
- Extract those files. Open ODIN and select the 4 files in their respective slots.
* IF YOU GET ERRORS such as model mismatch, start with 1 partition at a time to find out which one is throwing the error. (In my experience, it is the BL file that causes the error.) Once you find the culprit, throw that partition into the other ODIN. (For example, the BL file is giving an error in Comsey ODIN, throw the BL file in NORMAL ODIN and flash it by itself.)
* Typically you might have to throw individual partitions into either of the ODIN's but in the end you will be back on full stock firmware.



What doesn't work while rooted?

- On ANY ROOTED device, anything that utilizes "SafetyNet" will NOT work.
- Magisk and/or SuHide will NOT work. Our bootloader is still locked and these two modify the boot.img which would cause our devices to not boot up and having to start the root process over again, you have been warned!
- Systemless root also does NOT work. Again, this patched the boot.img which we cannot do because of our locked bootloader.
- Battery currently only charges to 80%. There are a few that feel it legit doesn't charge fully but others are claiming they get the same amount of life as they did with a 100% battery so the 80% might just be a visual issue or "fake" when it is really at 100%. Either way, we are still looking into this.

@jrkruse (for uploading system.img.ext4 and his root zip for the part 2 instructions)
@V0idst4r (for help in creating a "1 click" method for part 1!)

Initial Description on the process:
We are essentially flashing a modified 4 file firmware package in ODIN and then utilizing a few binaries in conjunction with SU binary and a permissive kernel. We will then be running some ADB commands and in order to have a fully working, amazing root with all things working we will be utilizing a stock system.img & a root script in conjunction with Flashfire. If you want to know all the technical details, you can take apart the files if you would like. It is released, so it is no longer a secret!


PART 1 Instructions: NEW

Flashing SamPWND 4 Files Firmware:
1) Download the PART 1 FILES Listed Below (this includes SamPWND_Root.zip and Initial ODIN 4 Files FIRMWARE and ODIN's if you do not already have them.)
2) Extract the 4 Files ODIN Firmware Package (also extract the ODIN's if you do not have them already.)
3) Open Comsey ODIN and select each partition and then select the files from the 4 File Firmware Package you extracted (BL goes in BL slot, AP in AP, CP in CP & CSC in CSC.) The options you select in ODIN shouldn't matter but I typically select F. Reset Time, Auto Reboot, Re-Partition, Nand Erase All & Update Bootloader.
4) Press Start and Wait for it to Finish. Once it finishes, if it boots into stock recovery simply select "Reboot System"

Take a breather, the ODIN portion is done (unless you have to start over for some reason...)

Now the NEW Root Process:
1) Once the phone is booted up, make sure you have ADB Enabled and connected to your PC. It should have prompted you to accept USB debugging as soon as it booted up.
2) Unzip the SamPWND_Root.zip
3) Double click "step1"
4) Wait for it to finish and once it reboots and comes back on you will be rooted with SuperSU!
5) Continue to PART 2 for "EVEN BETTER ROOT"
* It is a Windows bat file so not sure if it works on MAC. If you can't run bat files, use the OLD instructions.
* The bat will take about 30 seconds to run it's course. This is due to giving enough time for the remount script to mount the system as RW.

PART 1 Instructions: OLD

1) Download the PART 1 FILES Listed Below (this includes Systemroot + ADB zip, Initial ODIN 4 Files FIRMWARE and ODIN's if you do not already have them)
2) Extract the 4 Files ODIN Firmware Package, Also extract the ODIN's if you don't have them already.
3) Open Comsey ODIN and select each partition and then select the files from the 4 File Firmware Package you extracted (BL goes in BL slot, AP in AP, CP in CP & CSC in CSC.) The options you select in ODIN shouldn't matter but I typically select F. Reset Time, Auto Reboot, Re-Partition, Nand Erase All & Update Bootloader.
4) Press Start and Wait for it to Finish. Once it finishes, if it boots into stock recovery simply select "Reboot System"

Take a breather, the ODIN portion is done (unless you have to start over for some reason...)

Now the ADB Process to actually Root:

1) Extract the Systemroot + ADB zip listed below in an easy to find directory.
2) Make sure phone is connected to PC and ensure USB Debugging is enabled.
3) In the folder you extracted, you should see a "cmd-here" file. Double click it and it should open up an ADB cmd window.
4) Now we will start with the ADB commands:
- Type
Code:
adb push systemroot /data/local/tmp
What it will look like:
C:\Users\Thomas\Desktop\Minimal ADB and Fastboot>adb push systemroot /data/local/tmp
/data/local/tmp/systemroot/: 8 files pushed. 0 files skipped. 10.0 MB/s (7072263 bytes in 0.673s)

- Type
Code:
adb shell chmod -R 7777 /data/local/tmp
What it will look like:
C:\Users\Thomas\Desktop\Minimal ADB and Fastboot>adb shell chmod -R 7777 /data/local/tmp
C:\Users\Thomas\Desktop\Minimal ADB and Fastboot>

- Type
Code:
adb shell setsid su
What it will look like:
C:\Users\Thomas\Desktop\Minimal ADB and Fastboot>adb shell setsid su
(It will be blank with the blinking cursor, move to next step)

- Type
Code:
id
(you should at this point see that your are in a root shell!)
What it will look like:
id
uid=0(root) gid=0(root) groups=0(root),1004(input),1007(log),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats),3009(readproc) context=u:r:shell:s0

- Type
Code:
echo /data/local/tmp/systemroot/remount2.sh > /sys/kernel/uevent_helper
What it will look like:
echo /data/local/tmp/systemroot/remount2.sh > /sys/kernel/uevent_helper
(Again, it will be blank with a blinking cursor after you type the command in, move to next step)

- WAIT ABOUT 30 SECONDS BEFORE MOVING TO THE NEXT COMMAND

- Type "
Code:
mount
" (you should now see rw next to rootfs and system partitions)
What it will look like:
mount
(After we type in mount, we are looking for the below two items to say rw like they do in the next two lines)
rootfs on / type rootfs (rw,seclabel,size=1586716k,nr_inodes=396679)
/dev/block/sda19 on /system type ext4 (rw,seclabel,relatime)

- Type
Code:
sh /data/local/tmp/systemroot/root.sh
What it will look like:
sh /data/local/tmp/systemroot/root.sh
rm: /system/bin/install-recovery.sh: No such file or directory
cp: /system/bin/.ext/.su: No such file or directory
chmod: /system/bin/.ext/.su: No such file or directory
chcon: /system/bin/.ext/.su: No such file or directory
touch: '/data/.supersu': Permission denied
/data/local/tmp/systemroot/root.sh[55]: can't create /data/.supersu: Permission denied
chmod: /data/.supersu: No such file or directory

C:\Users\Thomas\Desktop\Minimal ADB and Fastboot\NEWSAMPWNDFILES>

5) If you followed all of the above commands to the T, your device will reboot and you will have SuperSU installed.
6) Install Flashfire from the Play Store.
7) Up to this point, you are on an ENG system.img with root that doesn't function the way we would like it to. This means you will feel a vibrate every time you try to gain SU access as well as it will take quite a while for an SU prompt. You can stay on this root if you would like to experiment with the ENG system, but outside of that I would HIGHLY recommend you proceed to the STEP 2 PROCESS.


PART 2 Instructions:

1) Download the PART 2 FILES listed below (this includes the system.img.ext4 and the add CSC Systemroot zip both provided courtesy of @jrkruse , view post #195 for specifics on what these are but essentially they are stock QD2 system.img and the zip has multi CSC, root, and a bunch of other goodies!)
2) Extract the System.img.ext4 zip and place that actual "system.img.ext4" onto the Internal SD Card (might work from external but some users have reported issues with chainfires root.zip and FF with external sd cards, this is not a fault of the SamPWND files/process.)
3) Place the entire Add CSC Systemroot zip onto Internal or Externdal SD Card (THIS FILE DOES NOT NEED TO BE UNZIPPED, THROW THE WHOLE ZIP FILE ONTO SD CARD OR INTERNAL)
4) Open Flashfire and grant it root when it prompts you. IF FLASHFIRE IS NOT LOADING FILES AND YOU JUST SEE A CIRCLE OR LIKE ITS CONSTANTLY LOADING, PUT THE PHONE IN AIRPLANE MODE AND THEN GO BACK INTO FLASHFIRE AND THE FILES SHOULD NOW APPEAR.
5) Press the + sign and select "Flash Firmware Package" & navigate to where you placed the system.img.ext4 and select it
6) Press the + sign and select "Flash ZIP or OTA" & navigate to where you placed the Add CSC Systemroot zip and select it, select Mount System as r/w
7) Press the + sign and select "Wipe" and select System data, 3rd party apps, Dalvik cache, Cache partiton, Cache Partiton format
8) Now, long press on "Wipe" and make sure it is on the top by dragging it. The order should be Wipe, Flash Firmware Package & finally Flash ZIP or OTA
9) Make sure the "Everoot" is disabled!
10) Flash away!

If you followed all of PART 1, then followed all of PART 2, then you will be updated to QD2, rooted with busybox (and have some other goodies) and the phone will be running great! Root will be stable and snappy as ever. Adaway, Root Checker, V4A etc. etc. are now all possible.

Dam it, if I wasnt drunk, and tired, I eould vet myself out of bed and do this now, lol. Thanks for all your hard work.

One thing i would suggest would be to either put the commands that need to be typed in as bold face type or im not sure if its possible on here, as im on my phone atm, but there are Code/code tags avaiable that will make them easier to copy and paste.

Again, thanks for this......I did not think it was going to be possible. This will be my morning present when i wake up, feels like Xmas.......

Where's the best place to get the stock firmware we might need just in case? As far as best download speed etc.

I got mine here... Took awhile to download... Someone gave me the link in the 955U1 thread

http://updato.com/firmware-archive-select-model?record=F6B451FD73EE11E7963AFA163EE8F90B


Also do we need to back up our EFS/Imei stuff? I know its recommended when flashing roms in recovery but our bootloader is locked.... Is there a way to back up without root?

Edit* I asked about the backup before in a previous thread but didn't get an answer.... Sorry to ask again

And this will work with Sprint S8+ Correct? Lastly, since the latest update which included Sprint LTE Plus calling. We will still manage to have that feature after root right? Because boy do I enjoy being able to browse the internet and being on a call at the same time again lol
If you have the system.img for the latest update then correct, if not and you want those features with root you will have to download the AP and CSC from thw firmware you want
