Either download Samsung KIES to your PC and install it (Samsung Kies 3 if you were using 4.3)
Then plug your phone to your PC
Either wait for KIES to do the emergency firmware recovery for you or find the emergency firmware recovery option and click it by yourself
Then you'll have a stock firmware
The warranty flag should be still there even you have new stock and official firmware
Second method:
Flash your firmware via Odin
You said you could enter Download mode
So flash it via Odin
Use CF-Auto Root if you want to root your phone when you fixed it
Good luck!

G800F: FAILED ODIN Firmware Upgrade. All Fail.

So I wanted to upgrade my firmware to the latest build, and having vast experience doing so, I downloaded from Sammobile.com the latest firmware build for my G800F and Odin showed "FAILED" with no error reported on the steps screen. Tried again, FAIL, swapped cables, FAIL.
I tried loading other firmwares...and nothing. The Download mode screen reads:
ODIN MODE

Any ideas or suggestions?

Try the Odin version contained in CF-Auto-Root
https://download.chainfire.eu/523/CF-Root/CF-Auto-Root/CF-Auto-Root-kminilte-kminiltexx-smg800f.zip
Have no problem with G800F and this latest 4.4.2 (15 May 2015) G800FXXU1AOE3_G800FDBT1AOC1_G800FXXU1AOE3_HOME.tar
Use Odin with admin rights,
don't know if necessary, but clear your internal storage and wipe everything before flash with TWRP:

Had the same on G800H while flashed latest Stock ROM published on sammobile.. finally the following steps a working (in my case)
flashing the stock firmware through Odin (ignore failed message)
take off the battery and put it back in
boot into Download mode.
flashing the twrp recovery
Reboot normal
The rom is now updated and had no problems with it (flashed it on this way 2 weeks ago)

+1 Worked like a Charm thanks "mind"
But now I have a new issue....I'm getting "Warning. Camera Failed".... this is like...a nightmare....damn.

Hello this method worked for me. Thank you. May I ask what version of TWRP this file https://www.androidfilehost.com/?fid=23991606952600970 is?
I am confused as after putting this via ODIN I still have stock android recovery when pressing VOL+ & HOME & POWER

Softbricked AT&T Galaxy S5

I purchased a soft bricked sm-g900a phone off of Ebay with the idea of using Odin to reflash and recover the phone. Since the phone was purchased soft bricked I do not have a history on what firmware was running on the phone or what the previous owner flashed that may have caused the phone not to boot to the OS or into recovery. I am assuming the previous owner was on 5.0 and tried to downgrade and ran into problems.
Short description of the current state of the phone:
1. Phone will boot into Odin Mode and can be flashed using Odin.
2. Phone will start to boot to recovery but sticks at "Recovery Booting. . . ." and reboots after about 30 seconds
3. Phone boots to Samsung logo and reboots after about 30 seconds.
What works:
Using Odin I can flash the following without errors: After flashing the phone exhibits the behavior above.
G900A_OC4_Stock_Kernel.tar.md5,
G900A_OA1_Stock_Kernel.tar.md5
G900A_OC4_Stock_Modem.tar.md5,
G900A_OC4_Stock_Partitions.tar.md5
G900AUCU3BOC4_OneClick..exe - reboots to recovery and "Recovery Booting. . . ."
I can flash SM-G900A_pit.pit with Odin 3.07 but not 3.09 or 3.10.
What does not work.

Same errors as above .
Tried to use Kies to recover the phone. It goes through the process of recovering with 4.4.2 and crashes about the same place flashing wit Odin does.
I assume if I could get into recovery to do a factory wipe I would be able to get the phone to boot. I have read multiple forum posts and blogs on getting the bricked phone to work where most recommend flashing G900A_Downgrade_to_NCE.tar.md5 and then if you can't get into recovery to flash either G900A_OC4_Stock_Kernel.tar.md5 or G900A_OA1_Stock_Kernel.tar.md5 and then you should be able to get into recovery. This of course has not worked for me.
Does anyone have any idea how I might go about getting this phone to boot into recovery? Also is it possible to have the local AT&T store re flash 5.0 on the phone.
I know it is a risk buying soft bricked phones but I sure would not like to have an expensive paper weight.

Its hard to tell what version it was on previously since recovery wont even boot, but from how its acting i'd say it was on LP and bricked for a KK flash, so you flashing NCE(Kitkat) is doing zilch. Seeing as there is no option for you to root, and im assuming you arent interested in that anyway, i would just take it to bestbuy or the att store and get them to reflash it, just say you got it off ebay and it was like that.

I took the phone to BestBuy and the guy there flashed it with 5.0.1 with the same results. Boots to the Recovery Booting. . . . screen for about 30 seconds and then reboots. My daughter is taking it to an AT&T repair center to see if they have any better luck.

Have you tried flashing the boot image?
Sent from my SAMSUNG-SM-G900A using XDA Free mobile app

Boot image. Not sure which file you are talking about.
Could you give me a little more information or a link to the file?

Re: Softbricked AT&T Galaxy S5
If you have the oc4 update zip, in the zip should be a boot image, create an md5 tar file from it then flash in AP. If that doesn't work, you flashed a bad kernel and may have to use jtag to fully recover. Or bring it to a repair facility to have them do it.

My daughter took the phone to an AT&T repair center and they also could not successfully flash the phone. The only OC4 update i have found is the G900AUCU3BOC4_OneClick..exe update and I do not believe I can extract the boot image from that update. Is there another source of the OC4 update available where I could obtain the boot image.
Thanks for the help everyone.

I'll look for the DL link. But if they tried flashing it, and it didn't work. You may be SOL.

Was scammed and bought bricked SM-G925A. Won't boot into recovery mode.

Good evening,
First time poster long time reader/browser. Before posting this message I have read all other posts/threads in an attempt to fix this issue. Long story short I busted my old Samsung Galaxy S6 Edge SM-G925A AT&T and bought this one used online. The seller never mentioned it was bricked as all pictures posted of it showed it operating and at least booting up. When I received phone I turned it on and it is stuck in a boot loop. I have tried to boot in recovery mode by pressing VOL UP+HOME+POWER button and it does nothing. I am only able to boot into download mode. I have attempted to flash multiple stock firmwares which 3 have been successful and passed in ODIN, however once they pass and the phone reboots it is still stuck in a boot loop. I have been successful in flashing the below firmwares. I do not know anything about the phone besides the IMEI number, S/N, SKU and manufactured date. I do not know what firmware was on the phone originally and do not know what was flashed on phone when I received it (I'm assuming phone was flashed or rooted before due to the above stating SYSTEM STATUS: CUSTOM) Am I stuck with a bricked phone? I've attempted flashes with PIT Files, w/o PIT FILES, with just the AP file, with all 4 BL, AP, CP and CSC files and each time it gets in a bootloop. Can someone please assist me? I've read that sometimes all is needed is to wipe the cache in recovery mode and that would clear bootloop, but I cannot get into recovery mode. Any suggestions. Again, below are what I've flashed successfully but continues to bootloop. Thank you all in advance.
G925AUCS5DPJ1--SUCCESSFUL ODIN FLASH-STILL BOOTLOOP
G925AUCU3BO12--SUCCESSFUL ODIN FLASH-STILL BOOTLOOP
G925AATT3BOJ7--SUCCESSFUL ODIN FLASH-STILL BOOTLOOP
I will say after flashing the DPJ1 files I can no longer flash the BL file for either of the 2 firmwares below it (the AP, CP and CSC files all still flash successful).
I'm just about to give up and shell out the money and buy new phone. Was just hoping someone on here could provide me some advice, some sort of miracle file or a way I can odin flash a tar/md5 file that will wipe my cache/system cache like it would as if you did it in recovery mode.
OH! Also Samsung Smart-Switch will not recognize the phone. I'm able to input the model name and S/N in the emergency software initialization but as soon as I input the S/N and click ok it immediately crashes and closes out Smart-Switch. Thanks Guys!

You need to find a Marshmallow odin file. The phone has most like;y already been updated to Marshmallow in the past. Once on MM, you cant go back to Lollipop which is what those 3 files you listed are.
Edit, NM....that PJ1 file is marshmallow. Try taking it to Best Buy and having them reflash it with the latest MM file.

Thank you, I will try that. I have tried taking to AT&T but they wouldn't help at all. They said since I'm not AT&T customer then I'd have to go thru Samsung. I'm aggravated. I've been working on this off and on for 3 months now. Thanks again for the reply. I've read a lot of people saying after wiping cache partition and rebooting it fixed bootloop after successful flash.
You said I could go back to Lollipop. If I use anything other than the 3 files I listed Odin will fail with various,
Secure Check fail message. Do you know if anyone has created a Odin file that will successfully wipe the cache partition like it would via system recovery?
Thanks again for the reply.

Any updates on this ? I'm having the same issue with my G925I.

why don't you try to flash the DPK5 update from ODIN in the nougat update thread. that's the latest ODIN file I think

No matter what I flash , it's always stuck on the s6 edge logo.. And I can't enter any recovery be it stock or custom recovery. All I can do is enter download mode and flash official ROMs but none seem to work.

Thats some unfortunate situation. I don't know what to do. If official roms don't boot then it's permanent brick I think. Any senior devs know what to do?

I am suffering from the similar fate,, its a friend mobile whose stuck on Samsung logo, he tried to fix it with Kies and Smart Switch and it did not workout for him.
The phone does not boot into recovery. I tried flashing G925AUCU1AOCE and G925AUCU3BOJ7 stock firmwares but no luck.
I successfully flashed G925AUCU6EQCF but it is still stuck on Samsung Logo
Any help or suggestion would be welcome
edit 3rd: Ok now I have managed to flash G925AUCS5DPJ1, still it won't boot into recovery and it is looping to Samsung logo

Same for me ... The recovery is not accessible and the phone reboots in a loop, Smart Switch tell me that the S / N does not match the phone model ...

Question Stuck in Download mode after firmware flash

Hi, I need some help flashing my device. Somehow, my device got stuck in a boot loop last night, and I've been having trouble getting it to work again. I think my phone may have reset during an update while in my pocket as I was laying down on the couch last night.
I found my device firmware on sammobile according to the specs listed below. I've downloaded Odin 3.14.4 and have flashed my phone successfully 3 or 4 times at this point, but when it restarts post-flash, it keeps booting into download mode. I can't seem to get it to boot into recovery mode or just turn it off at all anymore. No matter what, it boots straight into download mode.
Does anyone know of a way that I can force it into recovery mode so that I can try restarting it normally? This is my first time flashing a phone, so I have little experience here though I am competent with technology and willing to try further tricks to get it working.
I'm just looking for recommendations and hoping that my phone isn't bricked. I've only owned it for 3 months at this point, so I'm very disappointed.
Thanks in advance for the help, and I'm happy to provide any more information if it helps you come up with any potential solutions.

Do you have TWRP installed? Try flushing it. You can also follow Dr. Ketan ROM installation guide, it's very straightforward.

I don't. I was looking at that post earlier and noticed that it mentioned the G998B/N model. Mine is the G998U1, so I was worried that it wouldn't work or cause more problems. I couldn't find any versions of TWRP that matched my specific model.

your bootloader version is above v1. cannot be unlocked. you need to flash a samsung rom. try redownloading it if you can't boot. and twrp probably won't work either.
you're saying that if you hold the vol up key and power button when the device is off that it won't reboot into recovery at all?

I was actually able to get it to boot into recovery mode this morning. The download mode timed out and the phone shut off which allowed me to finally get into it. I tried redownloading the same rom I got from sammbolie again a few mins ago but still no luck.

Try another firmware with the same BL revision, CVC9 for example

Was your phone carrier branded originally? And you're flashing the u1 firmware so you won't have bloat? Or is it originally an unlocked model? I ask because if it was originally carrier branded and you used the Odin version from the SamMobile site then that may be the reason. U need to use the modded version of Odin that's floating around somewhere. If you need it I can upload it to my drive and let you download that version. I literally just flashed VCB last night and everything worked just fine.

No, I bought my phone directly from Samsung, and I bought the unlocked model. I chose the rom from sammobile that looked to be exactly what my phone originally had on it based on the model and PDA/carrier info I found when looking through the recovery logs on the phone when the issue first occurred, before flashing anything onto it. If you think the modded Odin might work, I'd be willing to give it a shot.

I can't tell you the exact differences, but I would flash with the patched odin. it's on xda if you search for it.

No luck so far. I've downloaded the patched Odin software and have tried flashing my device numerous times with the same result. I also tried tried flashing firmware that I found on Frija instead of the firmware I originall downloaded from sammobile to see if anything would be different, and that didn't seem to make a difference.
My best guess (could be wrong) is that it doesn't like the bootloader tied to the firmware I've tried to flash onto the device. I've spent a good while searching firmware that uses the version of the bootloader it wants, but I can't find it anywhere. At this point, I'm all out of ideas, but I appreciate everyone's responses and advice.

So this is what you are saying: You're using patched odin (https://forum.xda-developers.com/attachments/odin3-v3-14-1_3b_patched-zip.5158507/) to flash an official U1 Samsung rom (https://samfw.com/firmware/SM-G998U1/XAA/G998U1UES5CVCB for example) in the AP slot, all other slots are empty, without any odin errors during flash, and are then unable to boot, with partition errors seen in download mode? This is very unusual... flashing in download mode overwrites partitions, including recovery. I would assume if there are no odin errors, then the rom file is not corrupt and the sd card is not damaged. I don't know much about flashing through odin with a locked bootloader, maybe unpatched odin with the above instructions is worth a shot. I'm out of ideas aside from the sd card being damaged or trying unpatched odin if the above instructions with patched odin are resulting in recovery partition errors. I don't think you can access adb in download mode either.

You can extract the CSC file using 7zip. In there you will find the PIT file and you can try flashing it with repartition selected and inserting the PIT file in developers section of Odin.

Interesting. I did not try it with only the AP slot populated. I thought you needed to always flash with the BL, AP, CP, and CSC.

wait, i messed up. if it has all of those files, flash them. my bad. i was thinking about custom roms - sorry about that.

Hey everyone, just wanted to make a final update.
I ended up bringing my phone into ubreakifix after trying just about everything I could, and they were not able to fix it either. They suggested that it might be a hardware issue and recommended sending it to Samsung for repair. I then sent it over to Samsung, and they confirmed that it was an issue with my motherboard. Samsung replaced my motherboard, and the phone is back in action. Since I only had my phone for about 6 months, it was still under warranty.
I appreciate everyone who took their time to provide me with advice. I hope that this post may help someone experiencing a similar issue to mine in the future.
