You need to do it after flashing system.img. That was what I did and I'm currently rooted with VOLTE.

---------- Post added at 06:30 AM ---------- Previous post was at 06:22 AM ----------

Download the latest stock U firmware of your carrier from updato. Then use regular Odin with just f reset time and auto reboot checked AP, BL, CP and CSC. Then start over with root.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] lilrich17892:
I had similar issues. I could flash everything but neither Odin would let me flash the stock firmware AP. It caused them both to stop working. What I did was use smart switch. It said device wasn't supported. I clicked on the more button, then clicked emergency software recovery and initialization. Then clicked device initialization. I had to enter model number and press search. Then it asked for my serial number which I found by pressing *#06# in the dialer. It downloaded the software and asked me to put phone in download mode and connect to pc. It installed the stock firmware and rebooted. That was it fresh out the box
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] kcsevo:
How do i use smart switch? From phone or comp? And if comp how can i download it?

---------- Post added at 07:52 AM ---------- Previous post was at 07:48 AM ----------

Smart switch on phone is telling me to connect to an old device.

---------- Post added at 08:31 AM ---------- Previous post was at 07:52 AM ----------

Nvm. I downloaded SW for pc. I got through to those options like you said. But instead of hitting initlization i hit ok. Now SW freezes after i reconnect device and hit more, then emergency download. Dont know what to do at this point. I uninstalled and reinstalled with a pc reboot in between. Cant get back to that ootion no more.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] TT_Vert:
DO NOT use that supersu.zip provided it is only for t mobile I found out. (Check settings and also apps and you'll see some tmobile stuff in there. So first flashfire that QGL system.ini w/ the QG2_ADD_CSC_SYSTEMROOT you originally used. After this, reboot and ensure you have data again. After that youu now need to boot to the download mode, use odin and flash the CSC and CP from that same FW you got the system.img from (QGL). Then you'll be golden. If odin fails w/ mismatch then remove the .md5 extension from the file name.

How do you push the system root (8 files) in the first step for the adb???

keep getting an error "cannot stat 'systemroot': no such file or directory

EDIT:

Apparently, the issue is the systemroot file not in the adb directory, not sure what I am looking for here. WHY is this not in the OP's???
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] DaftOdyssey:
That's weird because the supersu.zip worked perfectly with me. :cool:

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] jhofseth:
don't flash userdata in Odin

It has probably been said, but I would avoid flashing userdata in Odin, because it flashes but it resized my data partition to only 9GB and I had to completely reinstall & re-root in order to get a normal size again. At least one other person had the same experience from what I read. :)

---------- Post added at 10:56 AM ---------- Previous post was at 09:59 AM ----------

Also, if you don't like Samsung's RCS icon on top of your phone (i.e., swirly white thing), you can do what some have done....

looks like some were using adb:

adb shell settings put secure icon_blacklist com.samsung.rcs
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Wacky2bakky:
So from here, flash that QG2_ADD_CSC_SYSTEMROOT in the original post in flashfire? Or do i need a specific file out of it? Then after that, i should have data back? Then flash regular csc not home csc and cp from latest fw with odin?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] braswellington:
Hey guys, idk what I did differently but I have never had the 80% battery problem. After root iv been able to change to 100% Anyone else have thv same result ?

Stuck

Can someone help me? I have the canadian s8+ and I was able to root with the steps but I would like to have it removed. Odin fails immediately when I try to flash my stock rom back and smart switch doesn't recognize my phone and I think it freezes when I try to recover it through emergency recovery. Anyone have any tips on how to get this removed?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] smooth703:
Is this what my build number suppose to be .. I redid all the steps flashed csc and cp.

Adaway still doesn't load and don't see the option for calling plus
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] mopartonyg:
Hello Jolly, it is in the OP. 1) Extract the Systemroot + ADB zip listed below in an easy to find directory. I guess the OP figured that anyone rooting there phone would have ADB experience. And then use his ADB by hitting cmd-here. And yes any files you are pushing should always be in your ADB folder.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Wacky2bakky:
See, that's what I couldn't get updated on my end was the build number. I just reflashed the system image from sprints AQGL ap file and the csc system root zip in 2nd steps. Now I have data again and still have root. About to flash cp and csc thru Odin from sprints AQGL fw to see if it corrects everything. I'm doing the exact steps everyone is recommending. I don't see why I can't just be on Sprints latest FW (software version, baseband,and build) with root so I get all the extra features. Now I'm back to model # G955U1 lol. Didn't get that until after flashing the csc system root zip in 2nd post thru flashfire
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Christogq:
whew i dont feel so bad now. ive been rooting and flashing etc etc for years now. never used ADB before. im beyond lost lol
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] mopartonyg:
Sorry for my ignorance, I guess that was my way of saying to read a little about all the different systems needed, odin, adb, FF etc. Not just jump in and then complain. Even experience users get stuck sometimes. After all the work done here this thread is full of complainers and critics and non readers. Sorry for the rant all. And OP and friends thanks for the great job.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
looks like aqgl to me???
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
it is in "OPS" and if you dont know how to follow instructions might want to hold off on root since it is a processand if u r already confused that is not a good sign

the adb systemroot files are in the download section, u literally unzip it and use the "cmd-here" to open a command prompt and systemroot is literally already in the adb root lol
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] smooth703:
I have data just a weird build number no calling plus and no adaway
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
u need to do step 2.. u are still on eng lol
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
bro u need to follow step 2.. u will habve issues with root on that build.. you can clearly see it says "eng" lol

if u dont complete step 2 u have been warned.. very easy to break stuff on eng.. i just spent the last 4 hrs flashing all sorts of stuff trying to unlock the bl lol each little thing i had to completely start over
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Wacky2bakky:
Yeah it was on the AQGL build but it had all kinds of weird settings. It wasn't Sprints stuff. Looked like Tmobile.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Christogq:
I can dig it. I just always figured ADB was just the regular command prompt. I went in and read everything but got sideways on this part. I have downloaded SDK tools and will try it from there. Thanks again to everybody that helped and the folks trying to do it. We will not be stopped!

---------- Post added at 09:48 AM ---------- Previous post was at 09:28 AM ----------

Annnnnnnd they're so cool that they put adb in there for us already. These folks are incredible.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] biotoxin:
finally rooted

guide needs more details though

reminder to be in odin mode, details on disabling everoot, what to do if flashfire won't populate, clarifying more on the ADB when not to expect anything (more going blank notes)

this being my 4th rooted device I will say it was relatively painless and an overall great job, can't wait to see where we go from here
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] mdiaz33685:
I was unlocked following the new instructions,

part 1- took me less than 5 minutes... :good:

part 2- took about 30 min, only cause FF was taking so long to read the system.img, just had to play with it a bit, :D :good:

then I flashed my Tmo rom with our latest firmware G955USQU1AQGA and made a copy of the original updater script so if we get unlocked BL just have to put the original back... so I edited not to run the Boot.img..... BOOTED UP ON 1ST TRY WITHOUT ANY ISSUES... :D

so far adaway 3.1 didn't work, looked around and found 3.2 build.. working perfect... also I used FF v60 with no issues...

like everyone says.... READ, READ, get ur files together... u should have no issues... :highfive:
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Christogq:
I think I'm struggling because I have no idea about ADB or even command prompts. Never got in to all that part. kicking myself in the ass for skipping class that day lol
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] mdiaz33685:
honestly I've been following all the threads, have my favorites in my browser all filled up, and had a word document with all the issues and stuff.. but didn't need anything, just all the files in the front.... except for I used the original supersu that was posted, cause the new one gave me some sprint stuff, so I wiped and flashed my rom instead of the system.img

I do not know to much with the adb also, I just copied and paste the commands and it worked fine... I see people get stuck when the cursor stands still, but the OP has been fixed and looks great, just keep moving through each step, and use the adb with minimal ADB, I had an older version, so I used the new version, and no issues at all,

if you get ur files together and put them in ur phone, just do 1 step at a time, 1st part should really be less then 5 minutes,

2nd part is just make sure u disable to airplane mode, and I put a copy of my rom, or system.img in my internal and ext sd..

like I said my biggest problem was FF reading the system.img or rom was taking forever to copy, a restart and trying again worked..
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
sounds like wasnt properly wiped at some point . had doubles and troaming n such in settings right
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
yea.. pplthink its terrible but in the end the part 1 only has 4 major commands haha which r really easy.. thats the push, chmod, echo and root.sh
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Wacky2bakky:
Yeah that sounds right

OK, been pushing the commands and something is not correct.

Code: adb shell setsid su

(It will be blank with the blinking cursor, move to next step)

Mine reads:

/system/bin/sh: No controlling tty: open /dev/tty: no such device or address

/system/bin/sh: warning: wont have full job control

dream2qltesq:/ # _

"the cursor is blinking, but locks up, you cannot type any further commands, only option is to exit adb shell"

Suggestions???

All previous commands do get the correct response.

So weird how Samsung's eng builds are so jank. Google eng builds are flawless they just take more space/memory due to everything being built with debug symbols.

Oh and they aren't rooted but they aren't signed with pros keys so you have to have an unlocked bl to run them
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Kjc99:
Might be a long weekend in this thread..... The OP is definitely idiot proof... I've never used adb before and did it.... If you type this it will show this... That made it so easy for me.... Also going back to stock instructions are all right there... If it doesn't flash put in modified Odin if still mismatched then put Bl in modified Odin flash then put Ap, CP, csc in regular Odin.... If you having trouble I recommend reading OP directions again...

I kept the instructions pulled up on my screen right next to Odin/ADB

Also flashfire will give trouble if not in Airplane mode (also in OP)

Hey all, I searched for yellow screen and faded screen and could but find anything.

When I am on a complete white screen (like Facebook) there is a fading down to the bottom and it gradually turning yellow with lines in it. I posted a screenie and I hope it's seen in it.

Anyone else have this problem or an answer for it? It's driving me nuts!!!

I hope you can see the fading gradually to yellow and the lines across the screen. I can't be the only one having this issue!!!

If you used the latest firmware and pushed csc and cp, that should solve the problem. That's how mine got resolved. And btw, supersu.zip worked perfectly with mine.

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] IJoxer:
Alright, I know this is a root thread, so I apologise if this is considered unnecessary clutter, but it's mostly relevant.

I couldn't find the link, but when I get home, I'll be sure to add it. There was a forum post concerning an S8+ user only being able to charge their phone to 80%, they contacted their carrier/Samsung, and was informed that it's a feature of the phone. Supposedly, if the battery is above a certain temperature, it won't allow you to charge past 80%.

I'm not certain, but this may be a clue on what we're dealing with for this root process. It isn't necessarily heating the battery up beyond the safety shutoff, but it might be a glitch that automatically enforces said shutoff.

Again, I apologise if this isn't helpful, but I know many of us would like the 80% issue resolved, especially those of us whom are completionist with OCD lol.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] JollyGrnReefer:
***WARNING***

Just want to thank the OP's and the community for the help in trying to achieve this root. Unfortunately, I was unable to complete the steps at the moment.

Through trial and error, the new ODIN3_v3.12.7 and ADB do not work on XP, since they are no longer supported. Reverting back to older/supported versions will not work successfully in pushing the commands via ASB. Ironicly, ODIN PrinceComsy works on XP, go figure. Was able to flash SAMPWND firmware, however, unable to complete the commands needed to complete root shell.

Phone is stuck on SAMPWND Firmware, unable to revert back to stock image since keep receiving errors in ODIN when flashing BL firmware. Once again, older versions will not work and auto fail. Do have a working phone with my carrier, so that is a plus.

Simple work around, going to reformat computer and install a linux distro. Been putting it off for a couple of years, giving me a lil motivation now. Then will complete the ADB commands to finish root.

Once again, this method is not achievable for WINDOWS XP. Save yourself the headache. I have lost the battle, but not the war.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] TT_Vert:
Yeah a few people have had the same issue w/ that supersu.zip. We also have no carrier either. Random Tmobile stuff all in there as well. I am on latest FW as well as the correct CSC/CP (See images). I have no idea why i have these issues. Can you do me a favor in adb shell perhaps and run two commands? They will just tell me what these are set at.

settings get global tether_dun_required

settings get global tether_dun_apn
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] TT_Vert:
Oddly, on my wireless charger i'm at 80% right now but it says 45 minutes until full charge. It may be using a calculation of current charging current vs. capacity vs history of full charge rate vs. time to come to that but I don't know.

**Update** I don't think this is a calculation as the displayed % is still 80% but now it says 38 minutes to fully charged after having it off the charger for a bit. So if it was using that 80% as a charged figured that time to charged shouldn't be moving that much.

I'll check back in about 40 minutes and pull it from the charger and put it back on and see if it says only a few minutes until charged or fully charged. The phone says 80% and it is still getting warm so it is certainly charging beyond 80% IMO. I'm going to have to check the current on this thing w/ my meter soon.

I find it odd that your apn is null. I may try that to see what happens. I specified the apn manually. Can you confirm you typed that APN command correctly? Did you have to make ANY changes to APN or anything related to hotspot?

Dave

---------- Post added at 02:57 PM ---------- Previous post was at 02:50 PM ----------

I also cannot understand why my build it NOT QGL but everything else is. My built shows QG2. We used the same system.img file as well as the same CSC and CP files.

Dave
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] IJoxer:
I'd have to agree, this information, along with other comments I've seen leads me to believe that this simply trickery. It may even be something that was baked into the boot.img for development reasons, either to test the safety shutoff, or possibly even calculations based on information regarding current batteries being more optimal when charged to only 80% rather than 100%.

I'm so very curious for whatever reason, and excited to see what other clues pop up about all this.
