Anyone want to help me make root for v3 bootloader on g950u - Samsung Galaxy S8 Questions and Answers

Samsung: We're patching SamFail.
Gavin: But I wanna roooooooot!
Melsbacksfriend: Don't worry, Gavin, I can help.
If you want to help me, then give me your email address. Mine is [email protected]. I bet that by that email address, you can tell that I like pokémon. I want this exploit to be called Submachine Gun 950u (as a pun with the model number that would work with any Samsung Galaxy S phone in case I want to make one for another phone like for example, Submachine Gun 930P for the sprint s7). I want the exploit to do more than just root your phone like partcyborg rom. Here are the things that I want it to do. Disable Knox, include Xposed, Have some humor involved (for example, a boot screen that shows a picture of an SMG, the number 950 and a Wii U:laugh, and improve battery life. I believe that we can do this if we work really hard and work together. I need your help because I'm only 16. There's no way I can do it by myself.

Successful Root?

Hey guys, another question here.
Ive been watching arters thread for some time now and i have yet to see anyone there post with the model [SM-G928P]. This model pertains to the sprint verison i currently hold but was wondering if anyone else with this model has been able to somehow root the phone?
Completely dumbfounded at how many models and versions sammy has released with this phone. Or maybe im the unlucky one and have the only P version in the world
Not complaining but was just curious is all.
arter97 said that he won't support Sprint.
Also as far as I know Sprint and Verizon has locked bootloader and when you root the phone, you won't be able to turn it on again.

Sprint can be rooted. It is not yet. See Sprint Note 5 dev thread for the "possibilities " The sprint s6e+ phone should have the same rootabilty as the Sprint note 5.

Thats sad to hear. Also i thought it was AT&T and Verizon with the locked bootloaders? Or was i mistaken?
Oh yeah sorry.
arter97 said he doesn't want to develop it for CDMA Devices, which is Sprint. So, someone MAY come up with root.
Hi
your answer is right and i am agree with this.Thank you for your informative task .
Thats sad to hear. It seems like a great start for the S6E+ however. Hopefully us CDMA users can join the party soon enough. Thanks for the info on arter AK. Appriciate it.

U Firmware Step By Step

Would Anyone Like To Post Detailed Instructions On How To Flash The "U FIRMWARE"? .. Also (if possible) could someone include all the necessary files & give any details on the firmware (i.e. Pros or Cons).. I've seen it mentioned in a few other threads, with some people making claims that it's much smoother, also the root is more stable on that firmware. But I can't seem to find a dedicated thread on it. So if there's one out there post the link or feel free to comment instructions, any useful instructions will be added to the OP

Hi, here's something from our friends with a Verizon s7 edge, they've written a step by step on how to flash the U firmware and what to do afterwards. What You and us t-mobile users need to flash is SM- G935U (TMO region) firmware which u can find on sammobile.com. Please read the instructions carefully and best of luck with flashing. Cheers!

Yeah it will but you need to find the right one on sammobile. The one for G9535T TMO region next to itself. The the rest of the procedure is the same as described in the post i shared. I will it leave it to you to do some research on your own and find the right files. Cheers!
Hey all, best place for U firmware is THEANDROIDSOUL.COM . they also have all other Samsung firmwares. So good flashing
Does it require root to flash U on the tmo variant?
Does it trip Knox?

Keep in mind there's also a lot in here that doesn't pertain especially if you don't need root so be careful people, this as Mag says is for Verizon but the process is the same just make sure you have the T-Mobile files if on T-Mobile. You can download at SamMobile I have a SM-G935T which is now a G35U with the new modem APK1 and have wifi calling and VOLTE in my mobile network settings and ZERO bloat which is why U firmware is desired. It doesn't have any carrier bloat because it's not for any carrier so none have installed all their bloat so it's very fast. You will lose root and everything but can redo it and reroot also.. just make sure you're getting the right files and not flashing VZW on to T-Mobile etc etc. I ALMOST did then realized lol. I Got excited. I was never going to root so none if that mattered but I tried it and after all the suggested tweaks and fixed it still ran unacceptable for me so I'm not rooted at all now. Too buggy and too many weird FCs and errors/bugs so I factory rest and flashed U and new modem and my phone has never been faster even when rooted and CPU setting tweaked etc. (Too many bugs as stated)

No because you're flashing an official firmware not a rom. No root and won't trip Knox as other have reported. This is true for all variants since it's an official firmware.

Prob not. Many people including me have done ALL of the post root modifying to make it run better when rooted with very little success. I tried every single post root method to try and get it stable and nothing made a difference and if it did it sure wasn't stable anyways. So bad that I Reodined the entire thing and started fresh and didn't root. The root is very unstable and simply not worth it. I don't need root for anything I care about anyway and my S7 Edge is plenty fast. and running the U firmware there's no bloat except like 2-3 apps which I can live with and that was one major reason to root anyway (to delete the bloat) so meh to root for me.... If you read back many have reported this. I don't need nor want root and when I saw how bad it ran I immediately re did it all. Now it's lightning fast, I get amazing LTE speeds because if the APK1 MODEM and I'm in one if the 319 cities supporting the 4x4 MIMO LTE that the APJ1 Takes advantage of. My LTE is faster than most people's wifi. So I recommend d regarding the Odin and forgetting about root. It's just too buggy and I'm by no way a noob. Been here fir 10 years so I know what I'm doing and I couldn't get it stable enough even applying every single post root suggestion. It ran like crap and wasn't even usable unfortunately. No offense to the root team whatsoever they achieved root and kudos to them it's just not established enough to be a daily driver sorry to say.
My latest LTE speed abiut 20 mins ago. Not wifi....LTE..LOL it's amazing if yoyre in T-Mobile and you're in one if the cities supporting it. I imagine everywhere in the US will sooner or later it most cities. It's relatively new but I'm getting speeds unheard of. Before this I was getting like 10 mbps download and 8 Mbps upload
Not it's more like 6p-70 and 40-70 depending in where in my city I am. It varies deoending on how close to towers and what not you are if course. But damn it's fast.. wow

is there a way to install this U firmware and then simply root it and not install all the other junk? I love it running U stock with the new modem because it HAULS ass, but I want to root so I can edit the build.prop and since you have to be rooted that's hay I ask. But the root causes all kinds of issues and post -root stuff needs to happen to get it even stable which none worked for me, a few did but it ran horrible so I immediately returned to stock and redid the U firmware. so is the something like a way to just root for file access only without it modifying anything else? I doubt it but don't know much abut the U firmware except it runs amazing until rooted at least from everything I'm reading. a couple peeps claim there's is running amazing even rooted but I have doubts...mine ran like total crap even after applying all the tweaks and kernel settings with Trickster and the like (which I know how to use very well and bought it and have owned and used it for years....any ideas? I want to edit the lcd from 640 to about 580 is all and don't want to root if it's going to bork everything up again...

Hi -
I am a person that just has to have his phone rooted. Dont ask me why, but I do. And I love custom ROMS. Since I do not really see any custom ROMS for the S7 yet,
I will settle for just rooting my S7, I was hopping someone would be kind enough to point me to the correct files needed to ROOT my phone and maybe a small odin walkthrough.
Phone info:
Galaxy S7 SM-G935T 6.0.1
Baseband G935TUVU4APK1

Also ... what about TWRP support ? I want to be able to nandroid backup. Is there a version of TWRP out yet for the S7 ?

Follow the instructions in the O.P. of the post-root issues *exactly*. Don't skip anything and don't add anything. Trickster is not listed in it. I followed it exactly and my rooted U just plain smokes!

The answer to both of these is that since the bootloader is locked, you can't install custom recoveries which makes custom Roms a lot harder (but not impossible!) There's two that are in the Roms subforum (TEK and Echoe) but I've personally found stock U firmware + root to be the fastest/most stable.

Is your reason for "have to have root" for a specific reason or no? This root us really laggy and buggy as hell so if I were you I wouldn't do it. There's no Roms really. Well two I think but it's going to be more if a headache than the benefit of root. No one "has" to have root. What do you need that's so important by rooting. That's silly....

I'm not sure bud. I LOVE the U firmware and the APK1 modem for Tmobile have made my LTE VERY fast and the U firmware as well with ZERO bloat. I wouldn't downgrade anyway but can't answer your question, I simply don't know. Are you on ATT or something?

Is there a root for the Unlocked S7 Edge US Snapdragon model?

I have a SM-G935U that I bought from BestBuy some time ago and I was wondering if there is a root for it. The carrier versions have a root, but I don't know much about the unlocked.
Did u find out? I thought the answer was a firm no since the bootloader is locked but I also really don't know what I'm talking about.

No, I never found out. I kind of just let it go. It's like people don't know the unlocked US Snapdragon version exists. Like how we got the Nougat update slower than all the other variants.
Check out the url I posted above. I guess you can now! And it seems really easy. (famous last words.)
Buried on like page 69 are even better instructions apparently. Here's a screenshot of what dude said to him to do.

S8 downgrade from Version 9

Hello, Smart people
I tried to search but couldn't find any proper solution. Is it possible to downgrade S8 running on Android 9, I want to install version 8 on it.
Thanks
i am also interested in doing this. i have had my phone for over a year, i was very careful never to download. the other day it popped up as i was taking a photo, and wham. normally i would have ripped the battery out of the back. but no such chances anymore.
the new os sucks huge. big stupid buttons, changes to the camera, the messages are pure misery.
i am on bootloader build 5. i have tried to use odin several times, only to discover this bootloader number thing on these forums.
im going to be furious if last week i was build 1.
at this point i would consider rooting the phone only out of spite to samsung for not letting me customize my phone anymore.

You can only go back to Android 8 if you have bootloader version 4. Use this code on your phone *#1234 # to know your version of bootloader.

If even OEM boot loader is downgrade is off, can I still do it? If it’s version 4?

You do not need to shut down OEM to downgrade! Respect only the bootloader version, otherwise it will brikar the cell phone, downgrade before the April patch as it is coming with bootloader version 5.

this is an s8 i am using, but i have a brand new s9 i have been holding back to use.
i want to fix the s8 before i stash it into storage as my backup.
can i downgrade the os to the former?
if not, if i root the phone, can i downgrade the os?

You can not because Oreo uses bootloader version 4, forcing a downgrade will turn your phone into a brick.

damn my bootloader says a bunch of numbers then 5 towards the end.
so that means im on b5.

He is right, I did not realize that you use snapdragon and there is yes oreo with version 5 of bootloader so you can do Downgrade normally.
thanks so much for helping guys!
what is the oreo version i have to hunt down.
im on t-mobile.
i tried to backdown using odin, it kept giving me errors. does odin protect the phone lol?
so if i get the proper oreo os, with the boatloader 5, odin will work?
thanks again for helping me out!!!

hey, which one is the one to use? android 8 is oreo?
i tried two 7.0's, and i might have tried the earliest 8.0 on this list.
do i just go higher up, and odin will just bang it in there?
thanks so much again!
I came back to the Oreo, well done system, with fluidity and great performance, Samsung Android Pie is crap.

Version 7.0 uses bootloader version 2, and there is version of Oreo that uses version 2, 3 and 4 of bootloader, do not use these, use this here to have no problems;

Samsung SM-A205U (Boost Mobile) Bootloader Unlock

I have searched everywhere on the web and none of the tutorials work to enable OEM Unlocking on my device. I'm trying to unlock the bootloader so that I can install TWRP and a custom rom. Any suggestions?

Sorry, Samsung have blocked the 205U
@RealBrianDuong @physwizz have y'all heard of any changes with this or any genius moves? lol

Could some also try to sum this up for a half ass noob with rooting and everything i've only rooted two devices but,
with this knox system i'd hate to trip something or whatever.
meanwhile this https://boycracked.com/2019/10/19/official-samsung-galaxy-a20-sm-a205u-stock-rom-for-usa-region/
website shows something that looks promising but what does this mean and is this bluff or workable?
if it could work please tell a dummy the best way lol
---------- Post added at 08:35 AM ---------- Previous post was at 08:32 AM ----------
on another note, if you can not unlock bootloader, how can you get to reflashing the stock rom like this site says and apply the cf auto root anyhow??? https://boycracked.com/2019/10/19/official-samsung-galaxy-a20-sm-a205u-stock-rom-for-usa-region/
You can't do anything much without unlocking the bootloader and Samsung have blocked the 205u
