Confused with flashing new firmware - AT&T Samsung Galaxy S8 Questions & Answers

Have a Galaxy S8 G950U that has T-Mobile firmware with bootloader version 7. Can not seem to flash any other firmware with bootloader version 7 with Odin. It just fails with no error code. Tried several different versions of Odin to no avail... any suggestions?

Possibly wrong version of Odin. 3.13 it's needed.

Yes thank you...finally figured it out because of the g7 bootloader..

awesome glad to see you got it

I was at bootloader v2 until I changed carrier to T-Mobile and they updated firmware to BL v7. Now I guess I am stuck here with no chance of root with custom FW. Not even safestrap has an update for BL v7...oh well not going to cry in my beer.

No not yet. I posted up the combo we need. For the boot img. But we still need the edl files.

Can you pass along the link to that thread....would appreciate it..by the way, is there a tutorial out there for learning to do the programming we need? I use to do commercial programming in COBOL, then some in visual basic. Might give it a whirl to try and help out where I can....

Is there any TWRP or other recovery for SM-G930V

Seems like the only recovery is see in TWRP is for the edge or international versions of the model, so I'm having a hard time adding a recovery. Can anyone help??? I'd greatly appreciate it.
No...the phone just got root and the bootloader is really locked down. No one saw us getting root, so who knows what can happen.

IF we get anything it will most likely be safestrap. So no AOSP.
Use FlashFire!

FlashFire is the compatible recovery. There are two ROMs for the Verizon S7 Edge. http://forum.xda-developers.com/verizon-s7-edge/development I have personally verified that the PlayStore ROM posted for the Edge will work on the S7 flat.
I should mention that you need to be on the U firmware prior to flashing those ROMs. The ROM also installs the G935 engineering kernel, so you need to flash the G930 boot kernel with Odin afterwards. I can make a write-up later if there is any interest.
I can even modify his ROM with the correct build.prop and kernel for the G930V.
How's the stability and finctionality?
A guide would be awesome. How do I get it up and running lol.

If you intend to root it, then you still need to use the same engineering kernel. I will say that before I rooted the U-firmware, the phone was much smoother and faster in stock form than the stock Verizon firmware.

Does flashing the engineering kernel unlock more LTE bands by chance? Band 12 to be specific..

Not just the kernel alone. Flash the U firmware and you will be able to select any band, as long as the radio is in the phone for it.

Thanks. Is it the G930U or G935U firmware that's needed? I'm guessing the Edge U firmware is what you're speaking of.. is it a simple flash? I'm running PE1 rooted at the moment.
930u for flat 935u for edge. Just flash entire image over. Shouldn't need root

OK I just accessed service mode on the PE1 firmware.. no Band 12 or 17 option. I'll flash the 930U firmware and attempt again to see if there's a difference at all.
Also, is rooting the 930U firmware the same as the PE1 firmware process?
Sorry for hijacking this thread.

I flashed the G930U firmware and was able to receive Band 17 successfully. Thank you for pointing me in the right direction with the U firmware!
Did you flash the 930U firmware on a flat S7 or edge Verizon variant device. I have a rooted Verizon device and using it on T-Mobile.
Version 6.0.1 July patch.
Can you pm or reply here on how you managed thanks
G930v custom recovery pass dm verity
Can someone point me in the direction of a thread to install custom recovery on the Verizon varient S7? Say hypothetically I could pass the dm-verity check.
How would I go about implementing the pass to install a custom recovery.

AT&T G950U (S8) stock firmware?

Does anyone have the AT&T variant ( or a link ) of the stock firmware for the G950U? Also.. could someone please explain how to go about flashing it over? I have a Verizon G950U.. my old Verizon S7 Edge I flashed to the AT&T firmware but it was much simpler... I used odin and just put in the 4 files ( AP, BL, CP, & CSC_ATT ) ... but after reading quite a few threads on here.... it appears to be a much more complicated process with the S8.

I have the same confusion. Did you figure out how to switch to ATT? i have an Verizon Unlock S8. Just downloaded the ATT firmware. Which instruction should i follow?
do i still need the factory binary and the canadian firmware?

please check, odin saids md5 invalid
Rename every file, remove the .md5 off the end.
That's ALWAYS step 1.
2. Use modded Odin
I've flashed it many times with no problem so if you're getting any error it's user error.
Ok, so I flashed the June att firmware sucesfully but when I booted it up, the boot screen still show custom. Anyway to fix this to not show anything like stock att?
nevermind, once rebooted again, it disappeared
Hi. is there a guide that shows how to flash ATT firmware onto the unlocked S8? Thanks!

Can you pretty please link the latest Revision 2 AT&T G950U Firmware? I cannot seem to find the Revision 2 Dec 20th Updated Release Build. I am pretty sure the build number is G950USQU2BQK5 but I have access to all the other variants on this update just cannot find the damn ATT version. I keep getting errored out writing the G950U1 XAA firmware, the G950U on all other carriers I get errors on it as well. I tried using Odin Comsy, Odin 3.12.7, 3.12.3 patched 256 version, 3.12.7, and even using the Z3X Samsung Tool Pro to reflash the firmware. I got one to finally take using all 5 files on G950U TMB but now the baseband is unknown and I cannot see the IMEI either. Anyone have any suggestions, I would highly appreciate that....
Flash QK5. It's for all carriers and installs proper carrier files and settings depending on the SIM you have installed. Use Prince Comsy Odin.
QK5 on Updato.com: (Labeled VZW but installs as ATT) http://updato.com/firmware-archive-select-model?record=0C70C888DEB811E7A5F9FA163EE8F90B

Me too, after latest OTA.

Downgrade from 6.0.1 to 4.4.2

Can someone please upload the stock rom, kernel, and modem for 4.4.2 NCG? I have tried atleast five time using what I thought to be the files and keep getting stuck on a black screen with a blue status light after flashing with flashfire from pb1 using the guide on the 'top topics'. Can someone please help me out?
What's the problem to pull it off the stock firmware?
BTW, I'd try BOK3 rather then BPB1.

I like the simple design and battery life of this version when I had it in 2014 on a G900A. This Marshmallow and Lollipop stuff is absolute bs. Battery life on Lollipop gives me 4 hours and Marshmallow about 2 hours. I'm hoping that KK would give me better performance and battery life on this G900V.

Yeah....This was a terrible idea. A auto update managed to install and I'm hard bricked. I'm not sure if it updated to the next update or to 6.0.1. Does you know where to find a debrick image?

Nope, only showed this 'Qhub' thing in device manager and didn't show in odin. Found a PD1 unbrick img, wrote it to a sd card with win32 disk imager, put in the sd, held the buttons for download mode, and it booted. Yeah, A total hard brick. I'm not gonna do that anymore, lmao. Found a great way to disable a phone though.
I also have a cid 15 g900v, what can that do compared to a cid 11? I know a bootloader unlock but what's that mean? I can install any rom?

Locked bootloader is called locked because it can only boot a signed, stock kernel (boot.img).
It's locked in SM-G900V by default.
CID15 means that you can unlock the bootloader and use a custom/modified kernel, if you want.
For example, it's necessary for LOS or for rooting on Android 6.0 and above.

So I could build roms if I wanted?
Or you could sell the CID15 phone to me via swappa to make a little $$$? I'm actively looking for one...
I just downgraded from BPB1 and unlocked bootloader and disabled Reactivation lock last night. CID (15) I think it's CID, but 15 none the less. Also I knew the login info for Samsung account. I believe you have to know. I still have all files, but I don't know how I'd get them to you. Also have a paid FlashFire.APK. I can also tell you what you need to fill when it comes time to flash NCG via FlashFire. LET ME KNOW, BUD. Took me months to find all files and the correct method. Now on 6.0.1. Fully rooted. :angel:

Help me identify the correct FW to flash/update to Pie 9.0

I have an Sprint Samsung S8. I want to update to Android Pie 9. Its currently on Android 8.0.0 - R16NW.G950USQU5CSA4. And I want to flash with Odin to any compatible Android Pie FW. I am personally not looking to unlock or anything. The confusing part is that when I research the FW version (G950USQU5CSA4) it comes as a Verizon FW. So I am not sure if is safe to flash any of the Pie FW available on sammobile for Sprint.
It is safe to flash for example to one like G950USQU5DSD3 that appears in Sammobile and is for Sprint?

Does flashing G988U sprint locked phone safe?

I have bought SM-G988U phone which is sprint locked. If i try to flash the phone with the unlocked U1 model would this unlock the phone or not?
Sorry For this but i'm still a beginner and don't know if this would fix my problem. If not, then what would you recommend please?
As far as I know it's safe....but as with anything involving modding your phone....be careful as one misstep could cost you.
Hey dude, I can confirm U1 works great on Sprint devices, currently using it and still getting access to the t-mobile 5g networks here in LA.

No, it will not Sprint device Network unlocked. Your device will still be Sprint locked. I do believe this model will actually fail if you flash in Odin. Sprint pretty much puts an MDM on their devices now preventing firmware flashing. If it does flash by chance, it will just remove Sprint's bloatware apps.

I have a Sprint S20 Ultra. I'm currently on Sprints latest firmware ATE6. I downloaded ATEC which is Junes security update with USC carrier. It is U firmware as well. I am trying to flash in Odin and I keep getting a fail. Any ideas if Sprint has now implemented something to prevent flashing of other carriers firmware? I never had issues with my S10+. This is the first time I am trying to flash firmware with my S20 Ultra. Help please
sigh. all you need is the latest patched odin and you can flash the u1 or other carrier u firmware.
i flashed the att U firmware to xaa U1 firmware. and then flashed to TMB U firmware
dont listen to other people who havent been in the odin game.

patched one
I used the patched 3.13.1 version. Yes it is safe, I'm running the Sprint version UI firmware. Originally tried with 3.14.1 and failed 3x's. Also tried the full International UI firmware unbranded with the 3.13.1 patched firmware and the phone would get stuck on the SAMSUNG logo. My phone is sim locked to Sprint though and that's why I think it wouldn't boot the full unlocked version. The Sprint branded version worked like a charm.
