I've tried flashing stock firmware, using various tools and applications, flashing a variety of files and rims but I'm still getting no where
I have access to Odin mode, recovery mode
And a beautiful Samsung flash image that is stuck in a bootloader
TWRP said android pie 9 ONE UI installed successfully, along with giving a mount efs error

Flashed MH8 firmware and now I'm in trouble

So I downloaded the latest UK firmware (MH8) from Sammobile and flashed using Odin, all went well and Odin passed and phone rebooted.
However now it just sits on Samsung logo FOREVER! I have reflashed firmware 3 times (every time it passes in Odin but still wont boot up)
I tried to reflash older firmware but that fails in Odin on bootloader section.
So I thought, all good I'll just flash Philz and restore my backup but now philz cant unmount System and I can't restore anything or even wipe system.
I'm pretty stuck it seems.
Does anyone have any ideas to help please
Flash mh8 in odin. Then boot into the stock recovery and do a factory reset.
I tried that 3 times but just tried it again and for some reason the 4th time it worked!!!
Still cant restore my old back up in Philz recovery for some reason.
Keeps failing on mounting system. Damn.
looks like I'm stuck on a stock ROM for the time being

Yep, that's the theory at the moment but if you go here - https://plus.google.com/+Chainfire/posts/5ggu7naWtaW
you should be able to re-root the phone.. Not sure if I'd try to flash a new rom just yet but at least you should get back root...
All reports are you can't flash an older version through ODIN because of the new bootloader...
Thanks again Chainfire...

Yeah at least we can root it now.
Still keeping my fingers crossed that someone will find a way to unlock the System partition.
I wish I'd never updated now, Samsung should of warned us that if we do this we pretty much lock down our phone

safestrap....unable to mount /system...potential brick??

have rooted s5 on 4.4.4 nk2. Have been trying to install custom roms via safestrap. Apparently i am missing a step. I wipe data, try to install twi5ted Lollipop on custom rom slot....blank screen for over 30 min after reboot, phone gets real hot, take battery out. Try to install on stock rom slot, reboot then get stuck in boot loop and keeps booting into system recovery. I then saw through my hours of searching to format instead of wipe....so i format then try to install, get stuck again, take battery out, get back to safestrap dash now when i try to wipe/format/or even restore my backup it says unable to mount system. When i click reboot system it says no OS installed. After reboot, my custom slot gets erased.
I was about to try an odin flash back to stock but some how was able to get my phone back to a system restore. Why can i not get anything installed? Do i have to have odin to do a custom rom install?????? i know every rom is different but wtf. I have seen multiple videos and threads of people flashing zip via safestrap and rebooting into new rom without flashing kernals via odin or safestrap after rom install.
Also...my phone will not let me download zip files (ex. cm12.1) says unable to create download folder....how close to F'in my phone up am i? I have successfully rooted all phones in the past...s5 is giving me hell!
I just tried installing rom after format, then flash nk2 kernel from odin, still gives boot loop....ive tried everything i have found..never this much problem with custom rom..
When you try to install twisted it needs lollipop firmware which is flashed on odin, and based on your statement it says you're on NK2, a kitkat firmware. Try flashing a stock ncg tar and rerouting, downloading apps, etc. on the phone to see if that works. Also, I noticed you mentioned a cm 12.1 zip not downloading which, while unrelated to your current problem, will cause a bootloop when flashed due to the locked bootloader on the S5, so it isn't a smart idea to even attempt an install.

thanks, i will try fresh from start ncg. so you have to be on the current kernel that you are flashing a rom for, whether its CM, Twi5ted, Alliance...etc i need to be on rooted 5.0 kernel then flash rom via safestrap?
i was having problems downloading from internet on phone, not downloading rom if thats what you thought i meant. I just tried installing zip for CM 12 via safestrap and got same issue. Phone reboots, goes to black screen and eventually heats up like crazy. .... I just noticed, after my restore ...again... it says safestrap disabled in red on the boot screen, why is that? it says installed and tried reinstalling.
FIXED
So i flashed ncg from odin on the messed up phone and got messed up worse. Ended up getting stuck on first boot image of samsung android s5 boot screen. Finally found original stock firmare file and used odin to complete install stock os and got rid of root. Now back to normal... luckily i figured it out my self! thanks to the 100's who viewed and didnt help and thanks to mrjiggywiggy for giving me some input to help out!

N910C EFS partition is ?corrupted? Not a single ROM boots. In dire need of help.

Everything was fine until I flashed CM13 unofficial.
Now, my bootloader is updated to 6.0 (COJ5 something or COH4), I can't revert to something prior to that: odin fails at sboot.bin NAND write start fail.
-While this issue has occured to many others than me, I'm the only one who can't even boot into CM13 or AOSP based ROMs, even after pushing different variants of ROMs several times through ADB, bootloops are still persistent.
-Any other 5.1.1 Official ROM that's not COJ5 or COH4 fails to flash at odin. COJ5/COH4 ROMS flash succesfully, but the phone doesn't boot past the samsung text.
-I have tried flashing various COH4 ROMS along with their AP,BL,CSC etc, everything flashes succesfully apart from the bootloader file, and after that it's the same samsung text brick. I couldn't find the PIT files (bootloader csc n such) for COJ5..
Is there a place I can find a backed up EFS partion ?file? and restore it myself? Would this get me out of the****hole i'm currently in?
What can I do about this...

Yea i came across this, but there was one tiny problem
how on earth am i supposed to root, get busybox, and apply usb debugging on my phone while it has no functional ROM?
and how on earth am i supposed to transfer a backup from my ROMless phone?
Do you have a pit file for repartition
If so, access twrp , wipe everything including your internal storage. Then boot into download mode.
In the computer, load the pit file and your stock coj5 into Odin 3.10 , tick "repartition" and "Nand Erase All"then click start.
Back to your phone - which now should be boot looping - access the stock recovery and wipe. Root - try using a different root method like chainfire's Odin autoroot - then twrp ur phone. Flash cm13 then start running the steps I threaded ( [fix] note 4 exynos bootloop problem ...... )

Might have Bricked S7 Edge SM-935FD. Need Help to recover

Hello guys
My phone is Galaxy S7 Edge Duos- SM935FD. I seem to have bricked the device.
Below are the actions I have performed.
1. Flashed TWRP using ODIN as described on https://www.the***********.com/root-samsung-galaxy-s7-edge/
2. Booted successfully into the OS. Found superuser app installed.
3. When I went to back to Flash ROM i erased multiple things such as internal storage/dalvik/cache/system after which device got stuck in bootloop. Showing NO OS.
4. I tried flasing Custom ROM Zip files through OTG. The process failed showing package corrupt and still stuck in bootloop.
I can enter recovery/download mode however cant seem to get the device booted. How can I get the device to work either Custom or stock ROM.
I will be going through some threads in the meantime, your guidance is very much appreciated.
Flash stock rom with Odin: This shouldnt be posted on Development Forum but rayher questions and Answers.
Find what your Stock Firmware for your phone is using Sammobile and flash stock then re do rooting and TWRP Process
zzThrain is right -- I wouldn't risk flashing custom ROMs at this stage, especially because many contain new bootloaders or other stuff that might make this even worse for you. Just pick up the relevant Samsung stock ROM file (from, for example, SamMobile) and see if it boots normally again. Once it does, re-do the process *after checking all MD5s of the files you used* -- I, too, have had it happen before that a download went corrupted and I flashed it. If all is well, get into Download Mode and let Odin rip.

Go to recovery mode & transfer rom to phone using pc. wipe cache, delvikcache, data only. No need to wipe internal sd. Install rom & reboot.
if you phone goes to recovery or download mode, no need to worry. If it doesn't go to neither recovery nor download mode, them your phone might have probably bricked.
It's my pleasure to help you if you still facing this problem

Hi
I tried flashing stock rom from sammobile. I could find for SM-935FD hence downloaded SM-935F.
It got stuck at 90% showing System in ODIN.
From the ZIP file which is the file that needs to be flashed among below ? I tried AP.
AP_G935FXXU2DRB6_CL12365438_QB16944063_REV00_user_low_ship_meta.tar
BL_G935FXXU2DRB6_CL12365438_QB16944063_REV00_user_low_ship.tar
CP_G935FXXU2DRAG_CL648265_QB8691891_SIGNED.tar
CSC_OJV_G935FOJV2DRAG_CL12785220_QB16560277_REV00_user_low_ship.tar
HOME_CSC_OJV_G935FOJV2DRAG_CL12785220_QB16560277_REV00_user_low_ship.tar
Now when I try again it immediately shows FAIL. Am i Flashing the right stock rom ?
It Worked. Thanks to all who helped.
I wasn't running ODIN as Admin and also was using an slightly older version V3.10.7.

I have an stock S8 that is boot looping. Do you think rooting or installing an different Rom is possible?

It's been a few years since I've done anything like this.
I can get into the recovery menus and wiped the device. It still won't boot normally or in safe mode.
Also if it's possible, what Rom would you recommend? I'm a Pixel user and really like it's UI.

I recommend to first flash a stock firmware to fix the bootloop.
You can check and download stock Samsung firmware files with Frija (https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910594/) and then flash it with Odin.
Check latest stock firmware available for your device first then you can decide if you want to test a custom rom.
I flashed the official ROM but my phone hangs on Samsung logo screen. When I open stock recovery (as I don't have custom one), it says dm-verity verification failed and when I boot up my phone, it goes straight away to stock recovery and logs show recovery reason unknown no such file or directory. I have tried flashing multiple times but no luck. Odin flash is always successful.
