[Firmware] G935UUEU4API3 Odin Files & Modded Odin

I know there's another thread for this but it's an absolute cluster F*** to make heads or tails of. I wanted to simplify things.
Simply download files, download modded Odin and put files in proper slots in Odin.
This is will give you stock U firmware with the latest PK1 modem. Root isn't what it used to be so I don't bother with it, please don't ask me for root files and instructions of this firmware.

Here's the modded Odin that I used. This is from the root thread and never once failed to flash anything on any device I've thrown at it: http://d-h.st/gsDA

Thank you for simplifying this process.

You're welcome. I'm here to help.... The other thread was too much of a mess!

Thanks joe3681, for all of your efforts.
Where online can I find a list of updates or a version history for the Samsung S7 Edge (T-mobile)?

so this will work with the latest update from November? and also what are the benefits of U firmware? I haven't been able to find any good info anywhere. i have rooted and flashed before lol i just haven't been in the game for a while

U firmware seems smoother, it's bloat free. Only real downside is no advanced messaging.

No, the U firmware is still the September security patch level. It's so much smoother/faster though. Especially rooted.

Thank you so much, this was obviously 100x easier to follow than the other thread.

I followed the O.P. in the post root issues thread, doing nothing more and nothing less than what they said to do. No lag, normal temperature.

Thank you
OP thank you for the easy to follow instructions. I just bought my SM-G935T from ebay. I noticed some lag with the S7 Edge and of course all the Samsung and T-Mobile bloatware.
I flashed all of the files then did a system cache wipe. I have not noticed lag so far and now have 20 GB of the 32 GB free.
One question though. Where will the phone check for updates? Will it get updates from Samsung or T-Mobile?

TWRP help
.
I just got my T-Mobile Samsung Galaxy 7 Edge and have been doing a lot of reading here on XDA about this device. I have had all the galaxy's since Galaxy II.
I have rooted / custom recovery / custom ROM all of them. I know there basically is not much out yet as far as ROMS go for the S7e, but I would like to instal
TWRP and root the phone. I can not seem to get a straight answer as to how to do this exactly. Each "How-To" that I run into are a little bit different and scares
me a bit. If you could help me with any answers or links to my question(s) I would sure appreciate it.
1) I would like to odin into the phone the latest TWRP but I am not 100% sure which file to flash.
2) I would like to ROOT the phone if it is fairly safe at this point in development, but again I have heard of at least 2 different methods to do this.
3) Please advise on which file to use and/or method. My phone DOES connect up with my PC just fine via USB and I have ADB working also.​

Well if you continue searching and reading some more, you will see that twrp only works on non locked bootloaders. Any carrier driven Samsung device has a locked bootloader and twrp will not work. We have the snapdragon and not the exynos. If you need to have twrp then you need to get an S7 edge Exynos version. There is no working custom recovery for the snapdragon version phones as of yet.

Yeah, you'd think! The international is the one that gets everything first.
The unlocked firmware favors T-Mobile though offering T-Mobile customers features that other users don't get.

You have to wait for TWRP to be updated to support the AQG5 bootloader, or install any of the AQG5 custom roms found here https://forum.xda-developers.com/galaxy-s8/samsung-galaxy-s8--s8-cross-device-development while using the AQF7 bootloader.

Are you saying this is not valid?
Plus if he's got an Exynos S8+, doesn't the S8+ TWRP already work on his phone? IF he also wants TWRP and not just root, he says. I'm not aware of any restrictions on TWRP for S8 Plus as long as he has Exynos, which he does. Yes, he's posting in the wrong forum (S8 instead of S8+), but other than that, please educate me where I'm wrong.

Besides the answers I posted for you above to root and to also install TWRP if you want, you should post over in the correct forum

You have a Galaxy S8 Plus, not a Galaxy S8. That forum is dedicated to same device you have, and more people will be there to help you even more. But the two links I posted should help you root your S8+ and/or you can install TWRP and root. With TWRP you can also install custom ROMs.

No. That link is not valid. As of today there's no compatible TWRP with new bootloader.

Those guides are usually just copy & paste of previous guides with updated version names and numbers. I wouldn't trust those sites, that's what we have XDA for, and if you look at the Question and Answers section you will find numerous threads of people having softbricked their device because of trying to root the AQG5 firmware. Custom firmware is the way to go right now and there are plenty of working rooted AQG5 custom roms here on XDA.

Anyway, you can't root with magisk on AQG5.

That's true you can't get Magisk by doing the CF auto root. But if you use a custom rom then you can have AQG5 and Magisk, you just have to stay on the AQF7 bootloader.

No that won't work. What you need to do is to use the TWRP update that can be found by joining the Telegram group found here https://forum.xda-developers.com/ga...pment/recovery-twrp-galaxy-s8-exynos-t3595102
If you use the regular update you need to flash the AQF7 bootloader - boot into TWRP - flash the TWRP update - flash AQG5 bootloader with Odin. Then you are free to flash Magisk or SuperSU.

Yeah the method posted (http://www.teamandroid.com/2017/07/25/root-xxu1aqg5-android-70-galaxy-s8-plus-g955f-nougat-firmware/) does not work. Plus there's that point that says "remove battery." Why and how would you remove the battery on a G955F? I like to root and just keep it as stock as possible but this method does not work.
Also when I posted a comment on this site it got removed.
"This method failed. OEM unlock on, USB Debugging on, drivers installed. In download mode the COM does not turn yellow. When I initiate this it fails. And why would I want to remove the battery? I don't have those kinda tools to do it, you gotta be kidding."

Finally I rooted My device Sucessfully....

need to root J327T1

Greetings,
Ive bought J327T1 today and i want to root my device which is on nougat.

You and countless others. Welcome to the unrootable device club.

the Sm-j327u is rootable its the same exact device as the j327t & t1 the only difference with that model is it's bootloader unlocked. the only solution i see is buying the unlocked version of the j3 prime from samsung's website. good thing about buying from samsung is the fact you can choose what company you want and theres none or less bloatware installed.
---------- Post added at 11:01 PM ---------- Previous post was at 10:52 PM ----------
also i have the link. i recommend that everyone buys directly from samsung for now on. remember one thing if your device has sm-XXXXU (X's in place of model numbers/letters) (U=unlocked and available on all carriers.) This is the death of unlocked bootloaders on carrier specific devices. the link to the phone is: https://www.samsung.com/us/mobile/phones/all-other-phones/galaxy-j3-16gb-2017--unlocked--sm-j327uzkaxaa/

We are working on it stay tuned a new thread will be made in the guides and news section if we are successful.

Update: we are out of ideas. Until someone has an exploit we cannot root this device sorry but you will need to either buy some other device or buy the j327u directly from samsung. It is unlocked and you can flash cf autoroot no problem. The only issue is we do not have twrp for that device yet but it will be soon.

for now its hopeless. samsung really pissed me off by patching the root method not even a month after it was made. sure performance was improved slightly but patching the bootloader is just too much. is having an unlock method too much to ask?

Really surprised me with Samsung to about this. They're normally pretty nice with OEM unlock and etc. Unfortunately this is just a phone they've licked down. They're Galaxy Note series all have root. So it really makes no sense to me why this one is so closed off.

Is S10E can be root?

https://myphoneupdate.com/root-galaxy-s10e-unlock-bootloader-install-twrp-recovery/
Can we root S10E with this link? I just found it on the web.

Seems like they copy and paste this "manual" for each and every (Samsung?) phone. First point : find me a home-button on the S10(e) ...

I don't believe TWRP is available yet on the S10, nevertheless the S10+ recently got rooted https://www.xda-developers.com/exynos-samsung-galaxy-s10-rooted-magisk/
S10e won't be far off

does anyone have tried the patch boot image magisk method ?useless to try ?

Check it out!! https://twitter.com/topjohnwu/status/1112611158735966209?s=19
The magisk Mastermind has struck gold again! This is no April fool's day joke! We are about to see payloads galore!!
Great work John Wu!

Why is it that I can't find any information on the status of the snapdragon version of the s10e root/bootloader unlock? I love this phone but I really need root. Does anyone know where I can find information or status updates?

From my understanding, if your model has the option to unlock the bootloader from developer options, then you can root. If you have a snapdragon varient, the only model that has the ability to unlock the bootloader is the SM-G9700 which is only sold in hong kong/china. I believe all Exynos models have the ability to unlock the bootloader, not sure though.

No one has rooted the snap dragon variant, but I'm sure it's possible. I just don't understand why there's no information or status updates on it.

Im pretty sure people are using the Exynos method on snapdragon variants that have the unlockable bootloader.

Don't be so sure about unlocking the US Snapdragon devices. There hasn't been a real root since the S7 series, the S8 root only works on some older bootloaders and crashing a lot, while the S9/S10 have nothing so far. Without an unlockable bootloader, it's extremely difficult to do anything. On the S7 it was possible via special engineering bootloaders, but that trick doesn't work on the S8/S9/S10 series coupled Samsung's new bootloader security measure via "VaultKeeper". Even on the Exynos versions it's a struggle to run Magisk, on every reboot you have to go through a bunch of steps to basically re-unlock the bootloader. It's basically game over rooting new US flagship Samsung devices, therefore you're better off with the international/global Exynos "F" versions.
