Hello,
i just flashed TWRP in Odin and now i´m not able to boot into Download Mode or Recovery anymore. When i just press the power button the phone shows the splash screen and the boot animation but doesnt get past that. I also cant reach the phone with ADB. Is there any way to flash a file without Odin/Download Mode?
Need help

i don't understand how you can't enter to download mode , did you do this combo keys (hold vol.down+hold home +hold power) right ?
are you sure flashed correctly twrp for your model device ?
if you can't enter to download mode , i'm sorry bro to tell you , your phone is hard bricked .

Maybe one of the buttons is broken or so. Sometimes it does boot to download mode, sometimes it doesnt. I managed to install a custom rom. I tried two Roms and none of them is able to boot. Both get stuck on bootanimation. I did not turn on USB debugging or allow OEM unlock in the stock rom before installing a custum rom.. May this be related to that?
Just tried a AOSP Rom (unofficial Lingue) and it booted like a charm. But Samsung Rom won´t boot. Do you guys know a solution?

if you can access to download mode .
1-flash latest your firmware
2-flash cf-autoroot again if you (flash latest marshmallow) by odin
if you flash nougat
1-flash latest twrp image for your s6 model
2-flash magisk root latest by twrp
after that you should access to stock rom

What's the difference between the firmware I flashed and this one you provided? I exclude a hardware failure because a AOSP ROM did boot.
Possible for the partition layout to be corrupted?

bro , the firmware difference between country and others , there firmware can't boot correctly if you installed on device , another firmware will boot correctly .
i don't think there are a failure on hardware cuz you can boot your device correctly and you can use it .
however , you can try flash this firmware without any problem , if also not booted you may need pit file for the firmware for Poland but first try flash without pit
if not work with you only (not boot up)
-flash firmware with this pit file together with
1-check option re-partition
2-make sure you check auto reboot and f.reset time
pit file for fimware

The Phone is from Germany, I would like to flash German firmware and pit if possible. Why did you exactly recommend this Poland version?
update: With the pit file flashed it doesn't boot either.

I'll flash it today when I'm home.
Yes I can, of course the stock recovery is installed now.
You need to install firmware via the 4 part binary method. Try the process below:
Download and run this:
Samfirm (on phone so having issues getting link, the software is on xda)
When you open the program, type the values given here;
Model: SM-G920F
Region: DBT
Auto: Selected
Manual: Unselected
Binary Nature: Selected
Check CRC32: Selected
Decrypt automatically: Selected
When you write and select options given above, press "Check Update" and then press "Download" to download factory firmware for your device.
Once the download has been finished, extract the zip file that you've downloaded via SamFirm.
After unzip it, download and run Odin
When you open it, press BL and select file which starts with BL from downloaded (from Samfirm) and extacted zip folder.
Do the same thing for AP, CP, CSC.
When you set 4 files to Odin, connect your phone to your PC in download mode and click "Start" on Odin
Credit goes to @forumber2 foe this process, it seems to fix a lot of stock firmware flash fails.

Then phone started to boot to dektop with some errors and i put hacker kernel s6 MM .zip
again flashed oldsboot (BL) with TWRP (AP) and i booted to TWRP recovery flashed hacker kernel and i made factory reset cach wipe then i flashed bootloopfix (BL) and stockrecovery (AP) and i did factory reset wipe cach and i managed to go inside Official MM with hacker kernel with no errors but the touchwiz sometimes fail but it comes right away....after this i downgraded to arter 5.1.1 back to note ROM i just wait to arter release MM back note ROM i dont like MM s6 i like note ported ROM..
first off all > sorry about my bad english
you need to install old boot lp then instal twrp lp and flash SuperSU-root-BETA-v2.66
then flash new boot mm
that is all

Install the zip with odin 3.10.7, like ap file( video tutorial) https://www.youtube.com/watch?v=TSNbHvJdTk4. Then reboot and celphone start working. This change your kernel and boot, but you can flash the original kernel ( i have if you needed). If you want root check this video https://youtu.be/0FEfJ4DWVcY

I had the same problem as the OP, and I flashed this kernel after flashing some stock roms, but it still doesn't work for me. When booting up, the phone no long gets stuck in the stock recovery but gets stuck in the Samsung Galaxy S6 Edge logo with the red tiny words on the top-left saying KERNEL IS NOT SEANROID ENFORCING.
Is this happening because I flashed a pit file the first time and maybe accidentally erased my EFS? I have made some backups using TWRP and an EFS BACKUP app before, but I have no idea how to restore those files now as I cant get into my phone.
Would really appreciate any kind of help.
In addition, I found that I don't seem to be able to flash a custom recovery like TWRP onto my device, at least I cannot get into it after odin says Pass when flashing.
I'm trying to use ADB but it seems the device isn't found.

I finally did it myself haha.
It turned out to be pretty simple; just in case someone is in my shoes in the future, here's what I did:
Flash a stock rom using Odin 10.7.
(IMPORTANT) Do not let it boot up til it says drk fail, hold down the vol down, power, and home button to get back into the Download mode.
Flash PhilZ recovery using Odin 10.7. arter97 . com /browse/exynos7420/recovery/twrp/g925fi/
Once it's done, hold vol up, power, and home button to get back into the Recovery mode immediately.
I'd personally do a wipe to make sure nothing goes wrong, then backup the EFS and other partitions while I'm at it.
Then choose Reboot to go back into the Download mode.
Now flash CF-Auto-Roots using the attached Odin. forum.xda-developers . com /galaxy-s6/orig-development/cf-auto-root-t3056630
Let it do the installation on the phone. It will reboot a few times I think, and hopefully when it says Pass, the LED indicator starts glowing. Then it should be all good.

i forgot to factory reset before i downgrade the os with odin. now the phone just stuck on the booting screen. i can get to download mode but not to recovery mode. anyone have some solution?
You could try flashing everything from the firmware you download from sammobile.com (BL + AP + CP + CSC (not HOME_CSC)) + check re-partition in Odin.
It will wipe everything. Be sure to download the correct firmware supposed by your hardware, else bad things may happen.

You can download the firmware from Sammobile, and flash it via ODIN, this should hopefully get you back to Stock OS.
You could also try to flash twrp img via ODIN and try to access Recovery Mode again.
Goodluck

Have you flashed the Appropriate Bootloader and Modem?
At what screen is it stuck at? You could use the Volume Up Key plus home, plus Power Button to force boot it.
Here check This link out, it might help you.

Well aslong as you can turn it on download mode you should be fine. If i was you i would download samsung kies 3 and put the phone in download mode and try to the firmware recovery from the top left section in the app. This will flash back the original firmware that came with the phone.,
---------- Post added at 04:42 PM ---------- Previous post was at 04:39 PM ----------
And if you flashed the CSC then you phone should be wiped when you boot it but maybe you flash the wrong file but like i said hard boot your device and set it to download mode and you should be fine
My phone is not working at all, it just sits in a bootloop. Samsung switch doesn't have my model, nor does their website. I've tried to flash the stock rom on my phone and it doesn't work. The only way it flashes is if I delete cm.bin and sboot.bin other wise it will just fail in odin. My phone is not supported that much I guess but even when I try to flash custom roms on my phone it is successful in twrp recovery but stays in a boot loop after restart. I don't know if I need to buy a new phone because for the last week I've been trying to fix a 200$ brick. Please help is there any other way to flash stock firmware other than odin. I've tried diffrent cables, ports, the whole works. What do I do?

ty very much but my model is not supported
Hello guys,
after days of reading and trying i decided to open a thread.
I got my Samsung stuck on Erasing Screen after an update.
I tried to Flash Stock Rom via ODIN. The Flash passed but after Booting the device stuck on the Bluescreen with "Erasing" on the bottom.
I tried Flashing with Pit, and without. With Nand erase and without. With Re-partition and without.
I can not access recovery with VOL UP + Home + Power.
Device is not rooted.
I am very thankful for any advice.
Thanks in advance.

Sorry,
it is a G930F
I downloaded the File from SamFirm (G930FXXU2ERE8_CL13438344_QB18102270_REV00) and used Odin3 v3.13.1.
any solutions?
I have exactly the same Problem.
Did you find a possibility to fix that ?
I´m going crazy with that my device is unrootet and on stock Rom when it came into bootloop , i tried to fix it with Odin a couple of times used the latest Firmware from Samfirm but it doesnt work and gets stuck on erasing Screen and keeps on restarting . I can always get into download mode but i cant open the recovery . Another thingis that my System Status in the download mode says custom ?? i never flashed a custom Rom on it Does anyone know if i can bring it back to Samsung like that because i still have a guarantee
i would be so thankful for your help guys
cheers
Had a similar issue before with an S6, and one of the workarounds that works for a lot of samsung issues is to flash the phone through ODIN with a repair firmware and a pit file. If im remembering right the firmware files are AP, CP, BL and CSC, also the pit file. you gotta check repartition in odin too.
any idea how to fix this ? In the same boat, can't figure out how to solve this.
same thing happened to me, i can't get it to work

can´t believe there is no solutions for this
i have the same problem with a galaxy A20 SM-A205G
i flahshed diferrent ROMs from diferent countries, with PIT FILE and without it and nothing works
maybe the difference with other posters here is that i can access to recovery mode but i dont find anything about fix this phone from recovery mode or something like that.
