Unable to flash stock firmware

Hello, my SM-G935A is rooted, and I have 2 issues with it. Firstly, I'm unable to receive texts or phone calls (I can send them), and I've tried a factory reset and I even got a new SIM, but nothing worked. I think if I flash stock firmware, it might fix the issue. Second problem, when I go into download mode and select my AP in Odin and press start, my phone gets an error and Odin freezes at Initialization.
Any help would be appreciated. I would prefer to fix the texting issue, as I don't want to return the phone to ATT. In either case, the Odin issue needs to be fixed

I'm having a similar issue. This afternoon, 2 apps threw errors and closed. I rebooted, which apparently was the wrong thing to do. The reboot stalled on the AT&T logo and stayed that way for 5 min - the unit became very hot & the power button did not respond, even while holding it down. I got into recovery, cleared the cache and factory reset, then rebooted. The unit came back up and started reinstalling everything. I took it back down into the download status and attempted to reload 935x via Odin, only to stall at "initialzation" [sic] as you did. I got out of that after waiting for some sort of response. SuperSU was still in my apps as was Root Checker. Root Checker indicates the system is rooted. SuperSU indicates it needs the binary updated. BusyBox and TiBu indicate they cannot find root. I deleted all the root apps and tried reinstalling root via adb which completed successfully, but the same outcome with all the root apps. So I'm not sure if I'm still really rooted as Root Checker claims, or not.
EDIT: I just saw that I have 2 "Knox Settings" apps. Clicking on either returns, "Unfortunately, Container Agent2 has stopped."

use the odin from the stock firmware thread to flash it again. if it fails you can flash the u firmware and then the stock again. then you have to use a different odin if you want to flash the root api file the one you flash the firmware with wont work. also there is help in one of the threads about fixing the volte problem so you dont have to turn it off to get calls. i didnt have to do it as using the odin i mentioned fixed it for me when i came from the u firmware.

I was having the exact same problem you had with Odin. It seemed I was able to flash stock firmware using this version of Odin: http://www.mediafire.com/download/2t2sjqxtogbkafk/odin_3.12.3.rar

did you have any problems with the u version of the s7 edge firmware, like the fingerprint scanner not responding? i am on that version and cant get any odin version or any version of s7 edge g935a firmware to flash, tried unrooting and was forced to use the U version of the s7 edge firmware, everything works except the fingerprint scanner, cant get back to full stock firmware, need help!

im having the exact same problem, when i put my phone into download mode and flash the stock at&t firmware, Odin get stuck in "initialization" and my phone screen displays and error message.

Same stuff was happening to me, I went back to stock and took the update. When your phone stops working as an actual phone, it's time to roll it back.
I played with it for a week and my phone was so freaking hot (with hot weather) equals a wait and see if this gets more stable in the near future. I did use the Odin 3.12.3 mentioned by King James III. Honestly, I did so many things to get it back to stock I forget what actually worked (it was the wee hours of the morning and I was spent). Don't give up guys, it will and can work.
edit: It may be as simple as not right clicking Odin and running it as Administrator.

I used Odin_v3.12.3_Patched_SHA256 to flash the 935U Firmware then used Odin3_v3.11.2 to flash the June Firmware release.

Soft-bricked AT&T S7 Edge trying to unroot / go back to stock

I'd attempted (and succeeded) in rooting the s7 Edge without much of a problem, it seemed to be working fine. I was considering flashing a custom ROM as well, but before I could get to that point the phone started behaving oddly. It would refuse to boot, freezing at the AT&T logo screen and vibrating in a 1-3 pattern (1 vibration, then pause, then 3, etc., ad nauseum). I realised I still had ADB access at that point in boot (somehow, I have no idea) and used it to reboot to bootloader and see what I could do with Odin.
ALL VERSIONS of Odin I have tried (3.12, 3.12.3, PrinceComsy variants of both) have failed to restore the stock image and unroot the device. I have attempted to use multiple different stock images I've found around these forums and elsewhere, and all attempts have resulted in either the phone throwing an error about the Odin version I'm using, or Odin itself telling me that the flash failed and the phone indicating some strange message about the boot or the firmware being 'fused' or something. Exact error is SW REV CHECK FAIL : [system]Fused 3 > Binary 1
All I appear to have accomplished is preventing the device from ever booting properly -- it refuses to boot normally, and by default enters Recovery mode (the stock recovery, which is essentially useless and won't do anything at all). I would very much appreciate some help getting this device off the ground again; I'm sure we can figure something out together! As I type this, I am attempting yet another version of the stock firmware I've dug up, so... fingers crossed that gets some better results. If not... please help. Currently trying the APK1 version of the stock firmware.
Cheers,

You have to use either the stock version of the firmware that your phone was on or newer. You can't use any older versions. APK1 is the latest version i believe. Use the official Odin. The .12 version and you should be good.

Thankyou. It took me longer than it really should to figure out which firmware version to load. Downloading that now... fingers crossed, heh.
Do you think it's worth attempting to re-root and install a modified ROM on it for the performance tweaks that I've seen cropping up here and there? Or should I just count it lucky it's still mostly salvageable?

Depends on what you want. Personally i would root it and go to the Verizon forum and download Stang5.0litre rom. That's an awesome rom. I'd stay away from echoe rom, seems like the devs are hit or miss on support. The dev for the stang rom is awesome and very active. I ran both of then and prefer stange.

Woah, woah, what? You can flash a rom based on another carrier? Will it still work? O.O

Yea it works. I know that one does. You'll get a message that says "unauthorized SIM card: or something like that. Just ignore it and use WiFi to setup the phone. Once you have it setup use package disabler or titanium to freeze "setup wizard" and that'll get rid of that notification. You'll have to manually setup your AT&T APN. After that your golden.

T713 owners, attention!!

I just flashed the latest XAR (cellular south) ROM onto a 2016 T713 and it's very, very good.
It's over at Sammobile FYI, I could not find a FAST download site, but they got it but good!
Just flash in Odin as 'AP' with no other options, WIFI WORKS FINE!!!!!

How have you rooted this? I could not find root info for 7.0

cf-autoroot-> https://autoroot.chainfire.eu/ SM-T713 -> https://download.chainfire.eu/1105/...uto-Root-gts28vewifi-gts28vewifixx-smt713.zip
SM-713 is build on QCO rom but also works fine with QD3 - mine is using the Cellular South QD3. Both are Android 7.0
Install using Odin and reboot. It may take a couple download/reboot tries due to some strange locking function on the Tab S2 but eventually it does install.

Whats the difference between the stock rom and the cellular south one?

I tried this twice, and both times when Odin rebooted the system it wouldn't let it reboot, and said "integrity verification has failed" and it wanted me to do a full factory reset, with a little button being the only thing I could press. So twice, I had to do a full factory reset.
Any ideas on how I can get past this part? I am using the latest version of Odin and the exact same copy of Nougat you are using. I have a SM-T713 that is the Nook version if that matters. I upgraded to Nougat because I wanted to be able to change the resolution for games like my S7 can with Nougat, but there is no option for it on the Tab S2, so I was trying to root to get access to change the resolution...
Thanks for any and all help.

1st thing, Titanium Backup is invaluable in this case because those wipes will delete your apps & data.
Before you started any of this did you go into the developer options and make sure OEM Unlock was turned on? You kinda need to make sure that is done.
Not sure if the Nook version makes a difference (mine is not) but the OEM unlock should do it for you. I always have to do the wipe thing after a new stock rom upload. Just a necessary evil I guess. I always let it fully boot and get to the launcher screen (I skip thru the setup stuff and use Titanium to restore things) before retrying the autoroot upload. For me it always takes after that first wipe (even repeated the whole process using the XAC -Canada- image today).

U System firmware on BLv5/6 Phone

1. Thanks to @FP_XDA and GSMZambia for the great directions found here
2. The other stuff and ideas:
The above method does put the U firmware on your phone. I had trouble getting it to connect to the network. I did try different combinations of files in the AP tar; CP; and CSC, but it would either not connect after a factory data reset or loop with the message about my SIM has changed, please restart.
I tried just flashing the following combinations through flashfire, but maybe this is a Sprint SIM issue and it works on other SIM cards; however, I have Sprint.
The U firmware seemed to work fine on the software. Including boot.img in flashfire would take away the eng_boot and root. I just had trouble connecting to the Sprint network.
Do you need to use the v5 combo file and flash a certain CP/CSC before going through the rooting steps? The U firmware CSC file is different in size, so is it a partition (PIT) issue since that will write the cache.img.ext4 file and those vary in size from stock to the U? Is there a certain order to flash in flashfire to get it to work properly?
Anyway, I downloaded several U CSC firmwares (XAA, XAS, SPR (last two are sprint)), but ran into some network issue every time. The operating system seemed stable, but the lack of connection and some random entries under settings make it so close, but yet so far.
I don't mind the Sprint firmware, but can you unlock additional LTE bands if you use the stock sprint firmware on another carrier?
Thanks for any help!

Here is more info about the Settings submenu options:
Here is some more detailed info:
The submenus under settings give me options like K twophoneservice; T roaming; Giga LTE. I think it is CSC related as those carriers are Korean based. I think this may be my issue along with a few others I've seen on reddit. Just wondering why it says that though. I used the G930U version, so not sure why this would appear.
Any help or suggestions?
Thanks

Bootloop
Did you get Oreo working while running on v5? Have followed steps in that video but the phone always gets stuck in a boot loop. I extracted the latest Oreo files from the AP file and every seems to flash right but gets stuck in a boot loop after flashfire reboots. Have tried multiple times with same result. Would rather not upgrade to v6 but was trying to get Oreo working.

I didn't try Oreo, but I didn't have any success getting Nougat to work. It would install and run fine, but I never got it to connect to a network. I tried flashing different imgs and making zip files with additional files to add to the system and same result. I do have additional LTE bands unlocked (12,13,17), but since I still have sprint, I have no way to test it.
I assume that everything would work normal except for VoLTE, but I think you could add that with root.

You have to follow the other guide on here about disabling packages. The only problem: you can't disable packages anymore with the apps from the play store. Samsung stopped that. There are system level applications that are blocking you from connecting to sprints network after flashing eng_boot. My guess is you flashed eng_boot, phone booted, then shutdown and reboot, now no network connection? This happens with the binary 4 version as well. I have been on nougat rooted using U firmware for a good while. I once had to re-install everything and when I went to disable the apps, I couldn't. There is a way to disable them via ADB but its not easy and requires patience. But once those packages are disabled, you will have a perfectly running phone with root.
Here are the packages:

The version used by GSMZambia includes a boot.img file, which removes the eng_boot and root after a factory reset. It sounds like you are actually still b4 for everything. This version is for people on b5/6 and want to install the U firmware. However, you are correct about disabling those packages when rooting on the U firmware. You lose root and eng_boot by flashing the stock boot.img in flashfire. The point is to have the U firmware without root on a b5/6 Sprint S7/Edge.
Maybe it would work if you flash the eng_boot again and disable, but then you are stuck on the eng_boot. Plus it messes with Knox, so I'm not sure if something like SABS or Adhell would even work.

But from what I read in the original post is that BEFORE using flashfire to flash the original boot.img, you are running the eng_boot.img. Is this correct? Btw, flashfire NEEDS root. So you ARE rooted at some point. Therefore, this is why you are being kicked from the network. Thus, disabling those packages will prevent that. But SABS and Adhell no longer work, at least I couldn't get them to. I even paid for the one and used it once. So I'm a bit annoyed with that. But yes, I am still on binary 4 for the BL. It was a requirement when purchasing my phone on Craigslist xD
But, what you are after may not be feasible. This is what you want: 100% U firmware on Sprint Binary > 4 WITHOUT eng_boot?
I always thought the whole point of being on U firmware was for root access though. But anyhow, once you get the U firmware flashed, which BL version is on the device? Is this an exploit that allows for older Binary to be flashed?
I'm intrigued by this method for other reasons. I would really REALLY love for a custom boot.img to be allowed but you can't. If this method is a way to block checking of BL, AP, etc hash checks, then the similar method should be possible for a custom recovery and custom kernel. I miss my kernel.

AdHell 3 still works on Nougat at least. You have to get the newer version because Samsung changed their SDK keys program. I'm not on Oreo, so I'm not sure if it will work. But if you are rooted, you have better options. If you need the new version of AdHell3, I'll post a link.

Basically, when you finish. You'll have the U firmware on the phone, but the BL with still be 5/6. So some things like Knox, System Updates, etc..won't work because of the conflict and will say the phone has been compromised. Also, the phone doesn't bootloop because of those items you need to disable, because you did it before using flashfire.
It works fine after applying the changes after rooting, but it is after the flashfire flash and factory reset that doesn't. Modem you can flash, but the CSC files mostly get erased because parts of them are install to the system with the rom. When you check, the phone has no CSC setup available. Which is why it probably displays Korean carrier settings since that is the default with CSC files present.

The original point of U firmware was to get rid of carrier bloatware and the ability to use most carriers easily with most addons (VoLTE) available.

So in conclusion, you have the U4 firmware running on a Sprint S7 with b5/6 installed without root. Since the phone runs fine with the U firmware, something is causing connection issues to Sprint. I assume he is in Africa (Zambia) and by using a GSM only sim card, it will work.
Unless you want to upgrade to b5/6 and try it, that's probably the only true way to test it. Plus, who wants to be on b4 anyway?

Yeah I am currently rooted with the U firmware BL4. I want to upgrade to Oreo, hoping for performance improvements, better battery, etc. But I guess since the Oreo U firmware is still BL4, I can just downgrade if I can't get root back.

I never mentioned a bootloop? Is this about something else? The point I am trying to address is the loss of Sprint connectivity after flashing eng boot. This is because of the packages that need to be disabled.

So you flash everything, eng boot, and are currently rooted. You then flash the provided file via flash fire, factory reset, and now you no longer are able to connect to Sprint network? When you say "can't connect to Sprint network", are you referring to data or to Sprint network entirely? If you go under your "about phone" section, what does your IMEI and phone number display? Don't actually type it here, but it should be something comprehensible. It shouldn't say "unknown" or a bunch of zeros, etc. [/quote]

I do. A lot of people want to be back to BL4. There is NO difference in the newer bootloaders EXCEPT a special "key" type of thing that prevents downgrading. That is the only thing different. This is why the U firmware is still on BL4 despite having an Oreo update. Sprint changes the BL version just so people like us have extra hurdles to overcome when we want something different. Its very stupid tbh.
But, I would like to help you guys out, however, I AM NOT upgrading to the BL5/6. Noway nohow.

It actually shows a crossed out circle for the signal strength in the status bar. I'm pretty sure I tried it by flashing just the system and system with boot, which removes the root. Even entering apn info had slight issues.
I was hoping someone with more knowledge and a b5\6 phone would give this a whirl. If you get bored, maybe it would be like you flashing the U firmware with b2.
My wife's phone is still b4, so at least one of us didn't get the Sprint screw.

Hmm. That's weird. What does your about phone section say for IMEI and phone number? Everything good? I wonder if something is affecting the PRL. Try updating that via settings menu before you flash the firmware and factory reset. The CSC shouldn't really affect that part. I have changed mine multiple times to just eff around and see what/if anything changed. Its more for the phone to know what menu options are available and such. For instance, call recording shows up when its not a US branded carrier.
Sadly I will never flash the newer BL. But I will definitely keep trying via the thread and if you would like to discord or something similar I would be down. School starts in about 2 weeks so I'm basically free till then

sim boot loop
I have the same issue. I can install the g930u Nougat firmware on my BLv5 Sprint phone (you seem to need BLv6 for Oreo), however, the phone will not connect to the sprint network. I flashed the cache.img file and it does the same thing. It forces you to reboot to finish setup then errors out on the blue sim card screen in recovery. I removed the AutoPreconfig app through adb shell to bypass the forced reboot and tried to just select Sprint as the network under connection settings where you can search for available carriers. That too failed...it just sat there for a while then said that it couldn't connect and shows the emergency calls only as the network up top and low signal bars.

Thanks for posting this!!! I'm glad that I wasn't the only having this issue. I tried it again using a different method and still got the SIM boot loop. This method probably works great if you have anything other than Sprint or Sprint MVNO, but something is conflicting like it does during a typical root of the G930P. Anyway, hopefully, someone else will be able to figure this out.

:( How can I recover this i337m in 2019

I have lost the phone that has been working for ages. I am broke atm. Please help I need to use my phone. I was trying to get my radio to work again because I lost data a couple weeks back. So I have spent more time than I even should have for this trying to fix it.
I have run Odin 3.07 with
lineage-15.1-20190210-UNOFFICIAL-jfltexx
lineage-14.1-20190212-nightly-jfltexx-signed
and
open_gapps-arm-7.1-pico-20190209
I have wiped everything and tried 2 different system boards ;
from download mode I have
used I337MVLSGQB1_I337MOYAGQB1_I337MVLSGQB1_HOME.tar
to reload with nothing checked but F. Reset Time.
pulled out the cable then the battery.
went straght to recovery (system was going there already) to do first stage unpack with android and progress bar.
It said BAR and END
I went in back in after restart, and a full wipe.
And after a long wait .. the system very glitchy, slow like something was running in the background (modem ?) if I open the phone app it wont close and calls are silent. then resets over and over..
I have tried custom roms, and flashing latest modem and original ? Whats up ? anyone
PLEAESSEEE help soon .. I am going crazy cuz this is literally my only phone and I need to use it !!!!
Had an old system board and tried to replace it and ended up in the same place with the second board ?!?! what is going on !

I know your post was a while ago but you cannot use Odin to flash a custom ROM.
Are you flashing the latest stock ROM from sammobile.com or updato.com?

I ended up using the pixel experience rom. I am sure I have the wrong bootloader and modem for i337m though. It works with data when I reset network settings and re-enable. Data each reboot. For the longest time lineage 9505 ROMs worked until like Feb 5th I saw the data just fall use just fall off. I couldn't get chatr to work anymore. It was a nightmare I went to stock and , pitted the phone and it would only function until I added TWRP and tried a nougat rom or even with latest modem. Wifi was evn a problem. Now I am using like a lollipop bootloader with the green battery charging and modem isn't right. When I flash a different modem and bootloader in Odin and rip the battery and then cableit doesn't even change .
Wtf?

I'm not sure how you could flash the wrong bootloader unless it was flashed using TWRP or CWM. To confirm, boot into download mode to see the model # listed on the screen.
Are the modem and bootloader matched; i.e. the phone is running a 5.0 bootloader and modem? To easily ensure that both are matched, you can flash the latest stock ROM using Odin.
If the modem version is not changing after being flashed, it is possible that the internal memory is faulty.

Can you tell me what version the latest boot loader and modem is for Canadian i337m

I haven't had an s4 for a long time but it was running the latest OH1 firmware: https://updato.com/firmware-archive-select-model?record=8D5422F720B911E6949E0CC47A44B7B2
