A thousand apologies if i've missed this somewhere. I just picked up the carrier unlocked S8 directly from Samsung during the $300 off sale. Their site specs say it's a Exynos and the "chat" chick swore i could use it on Verizon, will this method get TWRP installed?

Many thanks and again sorry if i missed this being addressed.

What's the model number?

[Samsung Galaxy S8 & S8+ Cross Device Development] chetqwerty:
...yeah, i guess i should have waited to ask till the mailman actually delivered it as that's a pretty important factor.
[Samsung Galaxy S8 & S8+ Cross Device Development] MeltdownSpectre:
If it ends with F (like mine), then it's Exynos and it's rootable and you can flash TWRP.

If it ends with U, it's Snapdragon, not rootable and no TWRP.

[Samsung Galaxy S8 & S8+ Cross Device Development] chetqwerty:
Thanks for the info. Reading a lot of other stuff on XDA about Exynos def not supporting CDMA but does support VoLTE so that's how the Exynos can work with Verizon. Sound accurate? Kinda lame though if it actually IS a Exynos not supporting CDMA being advertised as carrier unlocked. If i stray out of VoLTE range I lose service. Ok don't mean to hijack but someone may find the thoughts useful. Hoping for the best would love TWRP and root.

Thanks

long story but very useful for beginers !

just a week from purchasing my s8 device i decided to go thru my habit again

custamized Roms,

first of all i went thru all instructions mentioned in this post and folow it ( step by step ) to install TWRP and it was

success with no error.

then i rooted my devise using MAGISK ver 12 but this never happened !!

tryied so many times and read alot played so many videos to find out why ? but unfortunatly couldn't ( got same msg ERROR each time)

then i went for auto root using odin and yes it was working and superSU was there,

ofcourse it changed my recovery.

using my latest root i made a lot of changes to my device such as installing new fonts and apps and for sure i made s health app

work after changing the counter !snapchat never work and i know why but this is not the case

as soon as everything got stabled i felt board !! and tried to look at the MAGISK issue again

and flashed TWRP back and went for old Magisk ver 11.6 and it shows success but nothing there - no root -

this mean i wipe all things again !

here i told my self why dont you try to keep the new recovery which is better and install superSU from there

but guess what all my tries faild ( show success with no action )!!

and because i cant wait longer i accept not being rooted to finish some tasks and calls

during this .. i restore my data and apps thru samsung cloud which was backed up before the changes

and i discovered something very exciting

all my settings done while rooted was back ( font & s health ) and snapchat working just fine !!!

then i played again with settings and disable the OEM and USB debugging ( i know it is fool behaviour and dont do it ! )

and restart my system and then it got stock with baned error !!

no possibilty to flash any recovery or root anymore even cant go to my system !

now it is the major part

i flashed the origional software from samsung website using odin and able to restore my device with

all settings and apps again

my system now show ( status = Offical ) and able to get updates from air !

which means return to first square !

I flashed the latest 3.1.1.1 on my S8+ according to the instructions, but I can't boot to system. The device keeps booting to recovery.

I installed stock rom - no problem!!

Flashed twrp with latest odin, according to instructions on this thread - No problem!!

Flashed custom rom - No problem!!

BUT - Device keeps booting into twrp... NO MATTER what I try.

What am I doing wrong? Thanks

Did you format data and flash the disable decrypt zip?
[Samsung Galaxy S8 & S8+ Cross Device Development] smart_az:
hint :

both files ( no-verify & Magisk ) should be moved to PHONE NOT to external SD CARD

and flash them from there

( this caused an error for me while ago )

Thanks.. I actually flashed no-verify from sd card... Did not flash magisk at all

What's this file called "samsung-antiroot-removal-2.4.zip" all about? I have have seen this on a apparently reliable website? Does the file "no-verity-opt-encrypt-5.1.zip" now replace this or is the removal zip the old way of flashing/rooting?

Everything worked fine for me but then I disabled OEM unlock in developer options...

After i restarted im in a boot loop and I am unable to start Android Nougat at all.

Recovery doesnt work.

Download mode works.

I cant re-install TWRP if I cant enable OEM unlock in Android.

So basically im stuck!

Any idea's here?

Specs: Samsung Galaxy 8+ (SM-955F) with twrp-3.1.1-1-dream2lte.img and no-verity-opt-encrypt-5.1 with latest SuperSU v2.82

[update]

Sorry guys Ive been out of the game for a while.

I fixed it by flashing stock rom and re-doing the process.

Thanks for the advice.
[Samsung Galaxy S8 & S8+ Cross Device Development] gcarmagnani:
First ... how do you disable OEM unlock if the option was hided .... to prevent this cases.... ???

you have to download the stock rom .... flash with odin ... and redo all the process .......
[Samsung Galaxy S8 & S8+ Cross Device Development] crazynewfie:
Why would you disable OEM unlock? You will have to flash stock firmware through odin. Then enable OEM unlock again and start over.

Any tips how to do it as you need both hands to press the 3 buttons on the s8, how do you press the start one in Odin? :eek:

I watched 2 youtube videos for rooting the S8 but none are using the steps 9 and 10, they just press on start in odin and their S8 reboot in twrp, unless they already rooted before and they didn't need these 9 and 10 steps?

Also which one is better? Magisk stable v12 or Beta v13?
[Samsung Galaxy S8 & S8+ Cross Device Development] Trident10:

Hi,

Did anyone has issues on taking a TWRP backup on S8+ (G955F)?

I'm on Batman ROM with latest TWRP and when I try to get the backup it gives me ERROR: 255 when backing up the system.

Edit: I finally managed to take a backup by changing the backup location from internal SD to external SD.

Thank you.
[Samsung Galaxy S8 & S8+ Cross Device Development] SantinoInc:
Hey guys. I just ordered the G955F and was reading up on how to root and get TWRP. My primary source will always be from the dev's on XDA but occasionally I will follow along with a YouTube video https://www.youtube.com/watch?v=yqhdq_A47DY&t=355s&index=1&list=FLrrZcKioF-JslPjIgk-e1rg

This guy doesn't flash dm-verity but has some " Samsung Anti Root removal kit" that he flashes in TWRP with Magisk. IDK whether it's the same thing as DM-Verity. Anyone have any idea what that's about?
[Samsung Galaxy S8 & S8+ Cross Device Development] bassgenerator:

Am using version 3.1.1-1 now. As far as I know, ever since S6, all the TWRP I use can support USB-OTG. I install ROMs and apps via USB-OTG most of the time.

[Samsung Galaxy S8 & S8+ Cross Device Development] TarikVaineTree:
I've got two questions about this:

I don't care about KNOX but will Google SafetyNet still pass after flashing TWRP and if yes, do I have to take care of something?

My plan is to flash TWRP and Magisk to use Nintendo Apps (PGO, Super Mario Run) although I'm rooted.

In first post the following is written:

"3. Samsung Firmware OTA (aka System Updates) will no longer work once you flashed custom binaries.

(You can flash custom ROMs if you want to keep the OS up-to-date.)"

How can I receive official future updates by Samsung like bug fixes and stuff nonetheless? Can I download and flash them manually? Would I lose root (Magisk) or even TWRP by doing that?

Please quote me when you answer me. :)
[Samsung Galaxy S8 & S8+ Cross Device Development] Andysmith71:
Hey Guys, Whenever I try to do a full restore I keep getting the extractTarFork() process ended with ERROR: 255. This happens with every restore, I've even tried different backups from different days with same result. I've also tried the method of un-ticking Data in Mount, but this does not seem to work either. Is anyone else having this issue or are your restores working? Any suggestions?
[Samsung Galaxy S8 & S8+ Cross Device Development] ianmacd:
I also experienced this again today. I learned my lesson the hard way a few weeks ago, however, so I had also made a back-up with FlashFire. That one restored perfectly.

I have a 100% failure rate attempting to restore back-ups with TWRP. Back-ups made with multiple versions have all failed to restore for me with the dreaded extractTarFork() error.

As far as I'm concerned, TWRP is a handy little tool for flashing ZIPs when the device isn't yet rooted and FlashFire therefore isn't yet available, but as a back-up solution, it's thoroughly unreliable and therefore unusable.
[Samsung Galaxy S8 & S8+ Cross Device Development] Andysmith71:
Very interesting to see I'm not the only one having 100% failure with restores. I've never had any issues with TWRP previously (I've had both S6 and S7's and now S8+ so I'm not a newbie). Thank you hugely :good::good: for letting us know about your success with FlashFire, I'm using that as we speak to do a backup.

Cheers again,

Andy.
[Samsung Galaxy S8 & S8+ Cross Device Development] white7561:
Interesting. From the very first day. I never had any problems with TWRP. The backup restore works perfectly. Never had I get any error. PS : I'm backing up to an sdcard with exfat format. If it's not the same as yours. Try formatting to exfat. It might works
[Samsung Galaxy S8 & S8+ Cross Device Development] ianmacd:
My SD card is a 256 Gb Samsung EVO Plus with the factory-formatted EXFAT file system.

I've never actually had to call upon my TWRP back-up on anything but this S8+ before, so it could be that I would have had 100% success on previous phones, too.

On this S8+, however, where I have not only made back-ups, but also needed to restore them, I have yet to see one work; though all are successfully created and verified with no error.
[Samsung Galaxy S8 & S8+ Cross Device Development] ianmacd:
I'm not sure this is even TWRP-related, but in upgrading my S8+ yesterday to the newest firmware (AQF7), a strange new problem has popped up.

The phone now spends considerably longer on the pre-boot screen, the one that shows the model of the phone (i.e. not the flashing Samsung logo screen that comes after it). The screen also turns black for a second or two before the switch to the flashing Samsung logo.

It doesn't matter whether I boot to system or recovery, the delay is the same, so I reason it must be something to do with the bootloader, because it's before any OS or recovery code is called.

Once Android has booted, the only obvious negative change from how the system ran on the previous version of the firmware is that the phone now also takes considerably longer to turn on the screen (5 seconds vs. 1 previously) when I open the cover and bring it out of Doze.

I haven't tried restoring the stock recovery, but it's hard to imagine that that could be the culprit.

I reflashed all of the individual firmware files with Odin to try to fix the problem, but there was no change.

Any ideas?
[Samsung Galaxy S8 & S8+ Cross Device Development] force70:
Im not sure why taking longer to boot would be called a problem? Your device is fully functional so.....

Longer boot time may be something different than what your accustomed to but hardly a legit "problem".

Sent from my S8+, S7 edge or S6
[Samsung Galaxy S8 & S8+ Cross Device Development] ianmacd:
It's taking longer before the device even reaches the point of starting to boot. That's the key here. That's a fundamental change and hints at a low level issue.

Ane that's not the only symptom. I also mentioned that the screen is now taking longer to come on when the phone is woken.

And today I noticed a new issue: Do Not Disturb is now randomly enabling itself every few minutes.

Something is definitely wrong. The symptoms may be subtle, but they represent a change from previous behaviour, and that in itself is suspect
[Samsung Galaxy S8 & S8+ Cross Device Development] otonieru:
This definitely not TWRP problem,

Very high chance thats Kernel-Firmware-ROM-Magisk/Su mashup related,

What ROM and Kernel are you in?

My AQF7 booting in 14 blink of samsung logo (yes i count it, lol)
[Samsung Galaxy S8 & S8+ Cross Device Development] ianmacd:
I'm using the stock AQF7 firmware, but the number of flashes of the Samsung logo is irrelevant, because the delay occurs before that even appears. The delay is on the phone model screen. So booting into recovery is slower, too.

I agree that it's unlikely to be TWRP, but there was no more suitable place to post about the issue, unfortunately.
[Samsung Galaxy S8 & S8+ Cross Device Development] otonieru:
If you are rooted using magisk, try to reinstall magisk,

Used to have "longer than usual" boot previously, and it caused by magisk bad boot image patch
[Samsung Galaxy S8 & S8+ Cross Device Development] ianmacd:
I'm using SuperSU, but I don't think it's related to that, either.

I'm going to have to do a low level reset of the device, because even a normal reset isn't fixing it. I think the device is in an unstable, half-flashed state.
[Samsung Galaxy S8 & S8+ Cross Device Development] goRt:
I've reported, with logs, the inability to restore backups.

Someone always pops up to say they don't have an issue, then eventually reveal they are not using a stock ROM but custom.

No response from the Dev.
[Samsung Galaxy S8 & S8+ Cross Device Development] tiho5:
I follow the thread like many others and I see that in total the dev has only one post here other than the first opening posts.

I've not witnessed this in any other recovery thread, and I've had a fair number of devices.

I don't think he should have undertaken this project.

I haven't seen any absence of activity/support like that for a popular device like this and considering this is a "development" forum.

I'm not judging his knowledge or abilities, but the man obviously has no time, or isn't interested at all. Better to hand it over to someone else.

Need help. I am unable to get TWRP to work. After installing via Odin, TWRP boots but it failed to mount /data (invalid argument) then reboots automatically. When it automatically reboots, it goes to a Verification error. The only way I managed to get pass this was to install stock fw. Any ideas? I went straight to installing TWRP from a new phone with OEM unlocked. I am using the latest version of TWRP and Odin.

So many have issues here .. if you have any doubts from the beginning .. Do NOT start to flash just because you can follow a 1,2,3 list .. connect all the dots first before you start doing something, read other threads, specially from ROMs ..

This is the best manual I came across : https://xdaforums.com/showpost.php?p=72004368&postcount=3

It is not that complicated either .. just take your time, don't expect it be done in 5 minutes ..

Not working USB-OTG is not a little niggly issues.This is standard on every phone, but not on the S8.

P.S Text from Team Win website:

This is the Team Win website and the official home of TWRP! Here you will find the list of

officially supported devices

and instructions for installing TWRP on those devices.

Sometimes, firmware updates for a device break compatibility. If you have not updated the firmware on your device and the latest version of

TWRP is not working for you, you may want to try an older version.

With an older version, I have the same Problem.

I did not know that Alpha versions are listed there
