[Q] SGH-I337 (MDL) Stuck in Download Mode

After trying to install a custom recovery I have not been able to boot into my phone for about 4 hours now. During this time I have tried multiple times, using multiple methods and have found nothing to work.
My problem is when I try to boot up my device it wants to boot into recovery mode but it cant so it takes me right to download mode. In download mode I attempted multiple time to flash the default Samsung GS 4 .tar.md5 file and bring my device back to life but I get this error each time. (I've tried all my USB ports and still get the same error)

<ID:0/009> Complete(Write) operation failed.

I cannot find any fixes to this problem and have resulted in additional help from these forums.
Additional Info: When I was flashing my custom recovery, it was to overwrite the one I had previously installed (Safestrap v3.5x) with (OUDHS Touch CWM-based Recovery 1.0.3.4 by Shabbypenguin) and thats when I got the issue. Also, when I'm taken into download mode there is an additional red text above the "ODIN MODE" text that says, "Could not do normal boot." I'm thinking that Safestrap was attempting to boot along with the CMW-based and the device cant choose, so I'm forced into Download Mode.
Any help with this issue would be greatly appreciated. This phone is only 2 days old so I'm somewhat aggravated.

SM-G930A Bricked after trying to unroot.

Currently stuck with a Bricked Galaxy S7 that is in a Recovery Boot-loop. I tried flashing the stock firmware to the device and it failed.
Here is the Odin log:

The Screen after this failure displays the "Downloading, Do not turn off target" screen. And in small red font in the upper left corner of the screen the statement, "SW REV CHECK FAIL : [system]fused 3 > Binary 1" is shown. I don't have any clue where to go from here so any suggestions would be lovely.

I ran into same issue. Just hold power button until phone shuts down, power up into download mode and Odin flash the stock firmware for your phone again. It's a soft brick. Be sure you have correct firmware.

Same issue here - phone bricked. Odin or the Download mode of the phone fails with 1 of several errors. I have found that only 1 version of Odin works with my SM-G930A now. The last trick I think I have in the bag here is to pry off the back of the phone and make sure the stock firmware I am trying to use i the one that matches the device...
I have tried these stock images (easily google-able):
- ATT_G930AUCS2APF2
- G930AATT1APB5_User_Binary
The only version of Odin that works is the one I used to root the SM-G930A phone:
- Odin PrinceComsy.exe
It can only flash the root file:
- Samsung_G930x_QC_Rooted_BOOT.TAR
I have tried so many different versions of Odin, I think I am going cross eyed. If anyone has a solution for a phone that is looking bricked, please give me a shout out.
Thanks,
Aaron

I fixed my phone.
Answer for my case:
1. Load into Recovery mode
2. Reset factory defaults/wipe phone.
3. Clear cache
4. Reset factory defaults/wipe phone a 2nd time just for fun
5. Reboot phone
6. My phone loaded a long time through at the AT&T loading screen (it appeared locked, but was not)
- NOTE: You can always hard reset it and try to get through the AT&T loading screen
7. Go through Android/Samsung/AT&T welcome wizard
8. Root the phone: See permanent root section here: http://forum.xda-developers.com/ver...-to-notes-root-install-xposed-unroot-t3411039
- This root process side loads Chainfire's SU tool
-- NOTE: This is where things become unconventional, since my phone was not working with Google Play Services nor did the Google Store app work (I tried everything... they just would not work)
9. Open Chainfire's SU tool, go to the app's settings:
- enable SU at boot
- instead of "prompt", set app to auto-accept root access requests (normally this is stupid since some other random app could automatically acquire root access, but in this case, I was not in this state for very long. I actually had to do this because the system would not pop up notifications for apps requesting root access)
10. On a PC, download Chainfire's Flashfire app (I used this: eu.chainfire.flash_0.53-53_minAPI17(armeabi-v7a,x86)(nodpi)_apkmirror.com.apk)
11. In a Windows command prompt running as adminitrator, put the APK from step #10 into the same root.bat folder used in step #8
12. With the phone connected (with Samsung USB drivers installed of course), run this command from that folder: adb install -r eu.chainfire.flash_0.53-53_minAPI17(armeabi-v7a,x86)(nodpi)_apkmirror.com.apk
13. Open app drawer and run Flashfire
14. Follow this guide from step #1 through step #9 (because my phone will not work with Odin nor the boot loader listed on step #10 of the guide): http://www.droidviews.com/install-deodexed-debloated-stock-rom-on-att-galaxy-s7-sm-g930a/
- If steps are followed through step #9, the phone will be in Download mode
15. Hard reset phone and boot into Recovery mode
16. Repeat steps #1-5 from my steps listed above to reset factory settings / wipe the phone again
17. Phone reboots and will appear to hang... Just wait. Wait and wait. It will load.
18. Go through Welcome wizard...
This time, all apps work, due to the ROM image used during step #14. This slimmed down ROM image has fully functional stock apps, which is great because that is now set as as the factory image for any future Recovery mode factory resets. Life saver! ...or more like a phone saver for me.
Hopefully this helps someone else.

I know this is an old thread, but im having this problem after attempting to root to stock and im stuck on the samsung custom logo with recovery booting in the top left corner. the main problem though is i cant boot to recovery mode, it simply wont let me

[Need Help] G935A Bootloop

Now I've searched just about all of Google on this, but I haven't been able to find a solution yet. Everyone here seems to know the most about this kind of stuff so I figured I'd make an account and explain my situation.
Backstory / How it happened
So, earlier today I figured I'd root my AT&T S7 Edge, I used a tutorial from Max Lee (I can't post links yet but if you need to find it I'm sure you can Google it) to get the job done, and after a while I managed to get the thing rooted. I knew absolutely nothing about what the hell flashing, roms, bricked phones, bootloops etc. were and now I only know a bit about them. So the phone was rooted just fine, I had SuperSU running, and a few other root apps, but then I figured I'd install xposed installer. So I went ahead and downloaded the wrong version (whoops) and it installed its framework and then said it needed to reboot my phone, low and behold we have a bootloop. It stays at the AT&T logo indefinitely if I'd let it. I'll happily admit to that being completely my mistake, I read the warning that it may cause a bootloop but I went ahead and installed it anyway thinking I could fix it if it happened. (This thread is my walk of shame I suppose)
Solutions I've tried
Now that the background has been explained, I'll go through the list of solutions I've tried, mind you I'm no expert at any of this so some of the info I give may seem redundant or nonsensical.
- Rebooting into recovery and clearing cache and factory resetting in every order you can imagine
* Only interesting thing I could find is that it still says custom on both the download mode (the one where you press vol down, power, and home) and when you reboot the phone and it goes through the initial animation, it shows custom with a little settings-looking icon just before it goes through the AT&T animation and takes a **** on my self esteem.
- Waiting ~1 hour for the AT&T logo to change to something other than an AT&T logo (I was desperate)
* Yeah nothing came out of that one...
- Flashing every stock firmware I could find on the internet, with every version of Odin I could find.
* Kept getting the same error, "FAIL! (Auth)". I looked it up and all I found was old threads from 2013 on the Galaxy S4, with some now-irrelevant information, I couldn't seem to get it to work, but I'm positive that's what I need to do unless you guys know another solution. Here's the full log:

Don't know what I did but after that at the download screen it says at the top left "SW REV CHECK FAIL : [aboot]Fused 4 > Binary 2
Sorry for the wall of text, I tried to format it as nicely as possible to make it somewhat readable. If anyone needs more info let me know.

Can you flash TWRP? If you can maybe you can boot into TWRP and then try to flash any rom from XDA and see if it comes alive...

Thank you for the response
I've tried getting TWRP to work, but apparently there still isn't a way to get it working on the AT&T, I was under the impression that it was only for international and Korean versions. I haven't been able to find any version of TWRP that works for my device.
However I just did try some newer stock firmware from, "theandroidsoul" which partially worked, being that I'm desperate and don't know what I'm doing I just tried flashing all three:
G935AUCS4API2 - This one worked more than the others, but it seems at some point it disconnects for whatever reason, causing it to fail. After that my phone gave me the whole "You messed up go use smart switch" deal, and smart switch was saying my device was unsupported. That said I'm not sure what is causing the fake USB disconnect cause I can hear the windows sound for the USB disconnecting, but I'm not sure why.

I found it interesting that it got even less far than before.
G935AUCS2APH1 - Stopped at lksecapp.mbn then went to FAIL! (Auth). There was no disconnect or reconnect

I seem to be stuck in a similar situation. Did you ever find a fix?

I had the at&t s7 edge before and had the same problem but not sure if it was the same odin error.
But this is how you flash a stock rom on the at&t:
-You must use the princecomsy odin (search for it on google)
-Here is the stock rom with the latest security update (type "G935AUCS4BRA1" in the google search bar)
(I wasn't allowed to post links)
unzip and flash
tell me how it goes

Bootloop and can't enter recovery or flash stock rom with odin

Can someone please help me out
This morning i was running AlexisRom on my Galaxy s8 (SM-G950FD) which is an s9 port for s8 but the headphone jack wasn't working on the rom so i downloaded a stock rom from Sammobile and tried to flash it through odin, and after i put in the BL, AP, CP and CSC file and pressed start, it gives me a fail and says :

Also, i cannot get into recovery at all by pressing Bixby + Vol up + Power, it just bootloops
If i try install TWRP, my phone boots and shows the Samsung screen and says in pink writing on the top:
RECOVERY image signature check fail!!!!
Reboot to avoid warranty bit set!!
And i am 100% sure that the phone works as i had it working yesterday perfectly fine.
The roms i have installed before this one:
Stock S8 Rom
AMBASADII ROM FOR S8/S8+
Alexisrom s9 port for s8
Someone please help me out, if you need more details please ask!
THANKS <3

For anyone who has the same problem as me, here is a fix i found after almost giving up,
Go to Sammobile.com or Shell.BoxWares.com and download the latest firmware for your phone model, even if it isn't your country, still download and flash it, i live in ireland, so i should have 3IE Firmware but i downloaded the Indonesian firmware and it flashed without a single hassle

Its due to bootloader issue

You are trying to flash a old bootloader on top of new bootloader version, downgrading is not allowed AFAIK

There is a simple reason for this. If you came from TWRP as "reboot to download", this creates the problem. Turn off the phone. Go to download mode with Vol_Down+Bixby+Power and then press Vol_Up button. When I enter download mode like this, it flashes without any problems.

SM-G950F Unable to flash TWRP

Good morning,
I purchased this phone a couple years ago specifically for being able to root and customize my phone, I wanted to go with Lineage OS, but wasn't available at the time so I went with Renovate. Last night I tried to move to Lineage but failed, in fact I couldn't install any custom firmware's even returning back to Renovate. In troubleshooting I reflashed a stock image back to the phone and now i'm back to stock and working, but when I try to flash TWRP I am unable to I am getting only stock firmwares are allowed, i'm thinking perhaps I flashed a locked stock firmware. Looking at the developer options OEM unlock is enabled. Any thoughts, or help pointing me to a stock firmware that I would be able to flash to TWRP with?

The firmware has nothing to do with twrp so it's strange indeed. Can you get an Odin log from when you try to flash twrp? With this it's easier to identify why twrp won't flash.

Hmm the first screenshot, I've never seen before. Custom binary blocked due to remaining installment balance?! But from what I can see it maybe due to a network lock or OEM. Which stock firmware fo you have currently and what CSC?
