Updating/Flashing my S8+ from Verizon (Carrier Unlocked)

Solved
Used patched version of odin to flash the samsung unlocked firmware (G955U1) from the firmware servers. No more Verizon Splashscreen and spay/bixby work fine
I've been using android devices all my life and have rooted every single device I've owned in the past (probably 4-5 devices). I know the risks and I know how to flash my device and such but I got my S8+ from verizon about 3 months ago before the international unlocked version was released. I only bought it from verizon because their phones are carrier unlocked by default. I use google's project fi.
Verizon is somewhat good with bloatware I can disable or uninstall all of their applications and I haven't found my device to be slowed or burdened by their addons so I never felt the need to root my device which was nice but I got the Bixby update today and I cannot use it unless I update my system software. Tried to update it and it attempts to connect via verizon and ultimately fails saying it cannot connect to the update server. I expected this -- I think it's due to me not using verizon and not having the phone registered with their service.
Want to use Bixby and also would like to flash a stock updated (latest stock version) ROM as I don't care for any new features or custom ROMs because this phone is perfect as it is so far.
Phone software/model specs:
model is SAMSUNG-SM-G955U
kernel version 4.4.16 march 11th, 2017
sev 8.1
android 7.0
aspv march 1st, 2017
knox 2.8
If I follow my usual rooting route properly is it safe to root my phone? Asking because S8+ root is relatively new. I won't ever sell the phone so I don't care if the warranty goes void or something like that.
Essentially looking to turn my Verizon version into a completely US unlocked phone with a stock clean ROM. Is there any possible way I can perform this and still be able to use Samsung Pay? Not a necessity but I do enjoy it.

No root is out

Alright, If I flash the newest version of the samsung firmware onto my device (force update it) will SPay and Bixby still work? And my Knox will be fine?

Both should be intact and working as far as my knowledge goes Bixby for sure spay shouldn't be affected. Let me get this straight you have a Verizon s8+ flashing the unlocked firmware correct?

I have the S8+ G955U. It's verzion and has the ****ty verzion startup screen and sound it's just annoying. I really want to use Bixby voice as I just got the update from samsung but it says I have to have the newest samsung firmware to use it. I cannot update my phone normally because I don't use verizon I use google fi. So I want to try to flash the standard US carrier unlocked firmware onto my phone from sammobile (not the verizon variant). Is this safe?
the firmware list I'm choosing from: (spaces added so because account is not old enough to post links)
www . sammobile . com/firmwares/galaxy-s8/SM-G955U/
Which one on that list should I use? Obviously I'd choose the first one which is the Verizon firmware but I really would like to just have pure Samsung unlocked stock firmware so I don't have verizon apps & the verizon startup screen.

That's a tough decision I too have a Verizon s8 and it was plagued with the bloat and the splash screen when booting but I used a package disabler to get rid of many if the unwanted and unnecessary packages I didn't like as for using Bixby and getting rid of the splash screen.... It is safe to flash unlocked firmware many people have done this and there is a thread here on xda somewhere all about carrier switching the s8+ to the unlocked firm I could find it if you'd like?

If you could get that thread for me that'd be perfect. Thanks for the help. Really wishing I waited the extra 3 weeks and bought the unlocked version instead.

Updating because I was able to solve it myself. I used a patched version of Odin to bypass the model mismatch error and flashed a new system image and csc (G955U1 model image) that wasn't for my G955U Verizon model.
Bixby works, KNOX is fine, SPay is solid. Verizon splash screen is gone and the phone (from the settings point of view) has no carrier and is fully unlocked and void of bloatware.

SM-G930U root for v9 Bootloader "G930UUEU9CSA3"

i got the latest security update via OTA and an now running the G930UUEU9CSA3 firmware, ive tried flashing the eng boot img i originally used to root from here "https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616" but odin fails every time, i'm pretty sure its because the new security update updated the bootloader also... to version 9. now i guess my question is are there any eng boot files for the v9 bootloader available yet? or any other usable root methods available?

That wasn't very clever was it.
Should never update branded unless it's to fix a major bug. Any loophole which allows root or flash is closed on an update until someone figures out how to root on the new boot loader.
I think the best advice to anyone on US networks is to flash unbranded and go from there.

Get magisk.zip from internet , move to a sdcard insert sdcart to s7, Flash twrp for s7 then format data then click install magisk.zip reboot after finish and done.

I'm fairly certain that the only twrp for the s7 is a temporary one because there is no unlock for the bootloader, and even still the temp twrp is only compatible with the v4 bootloader and I am currently on v9.... that is unless I'm mistaken if I am then please someone correct me and point me in the right direction because I'd love to be running magisk on my s7 : )

No it most definitely was not very clever at all and unfortunately I'm stuck : / Also is the G930UUEU9CSA3 firmware not unbranded?

Yes it is I didn't read properly. Anyway what odin are you using to flash? The modified one?
We are talking about a qualcomm device yes?

Yes I'm using the modified Odin and all my previous attempts at flashing the eng boot files via Odin on the v8 bootloader have been successful, it wasn't until after the OTA that I started having issues.
And yes this is Qualcomm : )

Hmmm so it may be that loophole is now closed, what you need to think about is if you deffo need root? Or is it just nice to have. I'm sure a dev will get round it soon.

Okay I was completely unaware of TWRP being an option or the possibility of Magisk with a locked bootloader, now to clarify I'm running the latest unbranded US Region firmware for the US T-Mobile version of the Qualcomm Galaxy S7 "(TMB) G930UUEU9CSA3" that being said I have a few questions about how to specifically to proceed if you don't mind helping me?
First is the version of Odin available from the post provided above inst the modified version I've been required to use for all my previous flashing "Odin3_v3.13.1_3B_PatcheD" should I use this one or the version provided in the post above "Odin3_v3.13.1"?
My next question is that all the different versions and variants of TWRP available for my device the Galaxy S7 and the S7 Edge are either for Exynos Canada/International or Korea or the Chinese Qualcomm variant of each. Should I download and use the TWRP for the Chinese Qualcomm S7?
The sammobile link in the original post for "Android 8.0 Oreo Stock Rom" provides me with a list of the latest and up to date international versions of firmware for the Galaxy S7 Edge "SM-G935FD" I'm assuming I should just use the stock firmware image for my device "SM-G930U" instead?
The link for the no-verity-opt-encrypt-6.0 is dead but I don't think its needed because of something someone said in the original post about this method failing after latest security update "the one I'm on" https://forum.xda-developers.com/showpost.php?p=78115895&postcount=18 he said he solved it easily with information and another flash able zip from this post https://forum.xda-developers.com/showpost.php?p=77000849&postcount=47 and the zip from here https://forum.xda-developers.com/showpost.php?p=76564735&postcount=37
All that being said I haven't attempted anything yet, I'll try the above method as I understand it later this evening and I'll post my results

Hello there, i deleted most of your post because i didn't want my post to be huge. So if i just give you some guidelines hopefully you can have a look around for the files you need.
1. For Qualcomm / snapdragon devices you must always use the patched version of Odin you already have. Now this version of Odin can be dangerous if you don't flash the correct firmware for your device because it ignores device mismatch and other safety measures the normal Odin checks for before flashing. Which brings me to.....
2. Anything for G935 will not work for G930 including TWRP, you must always use firmware, patches twrp which specifically says it for G930 Qualcomm/snapdragon devices.
3. The China/ Korea Qualcomm/snapdragon devices are exactly the same as the US devices, anything working on the China / Korea devices will work on the US device.
Now i know you want to root unbranded on V9 but as you are on the T Mobile network it may be easier to flash and root T Mobile Oreo for the time being until there is a workaround root for V9 unbranded.
All of the threads you linked to were for G935 devices and i've mentioned you can't use those patches BUT the process and step by step instructions you follow are the same for your device. So you can follow those guides as long as you are using the patches for your device.
There is a Snapdragon section on this forum so thats a good place to look.
I've had a quick look for this specific firmware and can't find anything about rooting the U9 version yet.....
I'm just checking this firmware G930UUEU9CSA3 your running did have either XAA or USC code next to it when you downloaded? I've noticed Verizon, AT&T and Sprint are using the same firmware VZN, ATT, XAS.

I'd be interested to know how this turned out if the device with V9 bootloader could be rooted with temp TWRP method.

Can i actually flash magisk on my 930u?

Is there any way to root my g930t ?
I'm on v9 bootloader, and i don't care about knox tripping.
Did developpers really failed to break the security of this little old device ? Or no one worked it ?

You'll get updates sooner if you change to a CSC that Samsung releases updates for first, for example if you change to the German CSC (DBT) on an S9.

Do you have a locked bootloader?

The S21 series was released in January so it has not been seen.

If we use a December build on the S21 Ultra, any change that it could work?

You have bootloader 7, you tried to flash a bootloader 3. You need to use a firmware with at least bootloader 7. You can't revert bootloaders.
The 5th last character in the firmware version, identifies the bootloader version.

I have also confirmed that if you take any of the updates for the s20 note 20 or s21 variants with BL version 2, you will be stuck with whatever csc was assigned at that point without anyway to flash or change it. I'm working with samsung and local techs to find solutions.

Chimera Tool or Samkey is my only confirmed way to change CSC with February and newer firmware on the s20 and s21 devices.

I successfully updated the CSC in Android 11 with April patch on a rooted device using this method:
Install X-plore File Manager app or any other root browser from the Play Store
Launch the app, go to Root Explorer
Navigate to /efs/imei/ folder, edit the CSC code in the mps_code.dat file and save the changes
Reboot your device

Samsung Galaxy A71 5G SM-A716U Bootloader Unlock, Root and TWRP accomplished

The Samsung Galaxy A71 model SM-A716U by AT&T which has a normally unlockable bootloader has thanks to afaneh92 been unlocked. And he has made a TWRP version for it. Mine is now rooted with TWRP installed.
The version of TWRP was just built today by afaneh92 and it may still need a few tweaks per afaneh92 to be fully ready for prime time but so far it seems to be working fine. He was also very helpful in installing TWRP and getting root done on this model.
I'm not sure of all the details regarding how this locked bootloader is unlocked but it is a pay service that involves using your phones DID number which is then used to make a customized file for your specific phone and is flashed with Odin. Using afaneh92 for this it had a waiting time of only a couple minutes to get the file.
See this thread for afaneh92's info to get your bootloader unlocked on this model if you want root and TWRP:
Samsung Galaxy Bootloader Unlocks for normally unlockable Bootloaders
If there is interest I'll detail the steps to get all this done. I didn't have all the details when I started so I got help from afaneh92 via Telegram for the process. You will need to have Telegram either on your PC or phone to communicate with afaneh92 and to get the needed info and file built for your phone.

When you decide to unlock your bootloader these directions will help you be prepared and will avoid tying up afaneh92 too much as I know he barely gets any time to sleep with all that he does Since I'll assume you are not unlocking your bootloader for fun of an unlock the directions below will help you get Root and TWRP installed. TWRP is the easiest way to install Magisk and get root.
First you will want to do a complete backup of your phone. I suggest Samsung Smart Switch or MyBackup Pro or both
Then you need to get your phones DID number. You can see it on the download screen. Easy way to get into download is to turn off your phone, then hold volume up and volume down and the plug in USB cable to your computer (charger may also work). Then when you see the aqua color screen hit volume up to go into download mode. There are a couple other methods listed on the page afaneh92 has in the link above.
Save the DID number and it will be good to take a picture of the Download screen also as afaneh92 may request that.
Make sure you have the patched version of Odin from here:
https://forum.xda-developers.com/attachments/odin3-v3-14-1_3b_patched-zip.5158507/
Also get multidisabler.zip and vbmeta_disabled.tar if you don't have it.
Multidisabler.zip can be found here: https://forum.xda-developers.com/t/pie-10-11-system-as-root-
multidisabler-disables-encryption-vaultkeeper-auto-flash-of-stock-recovery-proca-wsm-cass-etc.3919714/
Also get the Magisk.zip file from here: https://github.com/topjohnwu/Magisk/releases/download/v21.4/Magisk-v21.4.zip
Then get on Telegram to contact afaneh92 from his link for his channel in the link above. Once you make payment he will get the .tar file for your phone. It can be just a couple minutes or a day or so I believe depending on his source being available. Mine only took a couple minutes. Once you have the fix file
for the bootloader unlock you will use the patch Odin to flash it to the AP section. Upon reboot the phone will take a little while to start up as it's like a factory reset and your data is wiped.
After you have gone through the phone setup wizard you will want to reset Odin, go into Download mode again and flash vbmeta_disabled.tar to the USER_DATA section in Odin. And if afaneh92 has TWRP available you can flash it into the AP section at the same time. Before pressing start in Odin be ready to quickly press volume up and power button once the phone reboots and the screen goes black. The release when you see the Logo. The you will be in TWRP.
Use adb to push multidisabler.zip onto your phone. Since data is encrypted at this point there is no use in
copying it there ahead of time. Just use "adb push multidisabler.zip /" which will copy it to root of phone storage where you can see it with TWRP. After flashing it do not wipe cache / Dalvik.
Then in TWRP choose Format data and type yes to confirm. Then reboot TWRP into recovery (TWRP)
In TWRP flash multidisabler.zip Then format data and answer Yes.
Then the best way to install Magisk is to flash it now from TWRP with "Install".
Reboot and check whether Magisk Manager is installed. If for some reason it isn’t installed automatically,
manually install Magisk Manager and with Wifi on allow it to do any updates.

Here is one other way to get your DID number (also shown in afaneh92's message thread above):
adb shell getprop ro.boot.em.did
or by Android terminal: getprop ro.boot.em.did

After talking to afaneh92 I believe he will be ready to release TWRP for the Galaxy A71 in a day or two. I am not sure yet if it will cover all the Snapdragon A71's or which exact models as I haven't asked about that but the one I tested today seems to work very well on the A716U.

This thread is where you can now get TWRP : [RECOVERY][UNOFFICIAL] TWRP for Galaxy A71 5G (Snapdragon)

Confirmed legitimate. Currently running his custom TWRP as well. He reaponded quickly too. It is worth the money to me.

So nobody's addressed the million-dollar question. What does Afeneh92 charge for this service?
Also, do we need to be on a specific version for this to work? I haven't updated my phone since I bought it because I've been waiting for a root method to be developed. Would he be able to root if I update to the latest software? Will I be able to update it after he roots it?
edit: nevermind the first question, it looks like the current price is $65 for the A71 5G.

The Samsung Galaxy A71 model SM-A716U by AT&T which has a normally unlockable bootloader has thanks to afaneh92 been unlocked. And he has made a TWRP version for it. Mine is now rooted with TWRP installed.
The version of TWRP was just built today by afaneh92 and it may still need a few tweaks per afaneh92 to be fully ready for prime time but so far it seems to be working fine. He was also very helpful in installing TWRP and getting root done on this model.
I'm not sure of all the details regarding how this locked bootloader is unlocked but it is a pay service that involves using your phones DID number which is then used to make a customized file for your specific phone and is flashed with Odin. Using afaneh92 for this it had a waiting time of only a couple minutes to get the file.
See this thread for afaneh92's info to get your bootloader unlocked on this model if you want root and TWRP:
Samsung Galaxy Bootloader Unlocks for normally unlockable Bootloaders
If there is interest I'll detail the steps to get all this done. I didn't have all the details when I started so I got help from afaneh92 via Telegram for the process. You will need to have Telegram either on your PC or phone to communicate with afaneh92 and to get the needed info and file built for your phone.

Hey man is yours from ATT ? I got my mom one and wanted to useon Cricket AIO . ATT owns Cricket and uses same network so does Safelink . Well cricket sim works for 5 mins no problem the says the imei is uncompatible. Safelink sim works fine . Are there some gsi for this phone ? That may help it or modules to spoof lol .

Hey was wondering if anyone has or can make a backup of modemst1 and modemst2 for A 71 5g snapdragon ? I had an issue registering on network and found a guide using fastbootcommands to erase those and that would fix it. However now it won't recognize any sim card and I've downgraded and did Ota to 3.0 again after formatting data in twrp. I ve tried twrp backup and that didn't fix it .

Hi,
You mentioned the A71 A716U and in the OP mention "AT&T". Is that what the A716U is? The AT&T model?
I ask because I just bought two of them, but they're Unlocked and someone else is using it with my Carrier (MetroPCS, now called Metro by T-Mobile) and so it didn't mention which Carrier the model normally ties to.
If so, I still use this same BootLoader Unlocker that he creates, right? I definitely want to Root both phones.
I didn't see the steps for Rooting here (I think you mentioned listing the steps), but I'll keep looking.
Thank You,

hi Zeus i believe the A716U is the north american A71 5G and diffrent cell carriers can be flashed for the firmware part, the carrier lock is i think controlled by you but you've got to ask your cell provider to unlock it carrier wise if you owe nothing for the device and it it isnt blacklisted or stolen the imei, also the devices are usually? branded one particular carrier, to find that out go into download mode and it should have a csc cell provider code at the top. =) hope this helps?

Hi,
I went to the link where the "multidisabler.zip" file is and got that, but when I looked for the "vbmeta_disabled.tar" file, I don't see it on that page. Where can I get that one, please?
I ask, because I've never heard of that one before and so I don't know if it's specific for this phone and so was worried about just grabbing any file from wherever (on XDA) with that name.
Thanks!

Oh, maybe I wasn't clear (my fault). I don't mean the Cell Carrier. I bought that part Unlocked. I'm talking about Unlocking the BootLoader.
Thank you for taking the time to respond! I appreciate it!

Hi no bootloader unlock for DUE4 yet thank you

No Android 11 update available

Just purchased new Galaxy S10e and it won't update past Dec update. It says no more updates available. I'm on Verizon network. Any ideas?

If you have the U1 variant with unlocked bootloader, you can download latest firmware for your device e.g. with Frija and flash it with Odin.
If you have the U variant with locked bootloader, then you have to wait for Verizon to provide the OTA updates.

i upgraded my galaxy s10e (exynos) to one ui 3.1 and it's showing a lot of lag, and the camera takes time to open and take a picture. (Can anyone help me with this) ? is its performance normal with the one ui 3.1?

reboot in recovery mode (phone needs to be connected with computer by USB), wipe cache followed by repair apps.

To receive OTA updates (from Verizon), you have to stay on original Verizon firmware.
If you are sure that there is already an update available from Verizon, and you do not get it over the air, then contact Verizon support.
Flashing a firmware of another device model into your phone may brick it and you will lose any warranty and support.

1. The U1 model does NOT have an unlocked bootloader.
2. You can manually upgrade either model via the exact same process: download firmware via Frija or wherever and flash in Odin. Waiting for OTA is *never* required
