G925F Unbrick help with a solution - Galaxy S6 Edge Q&A, Help & Troubleshooting

S6 edge stuck on opening logo of "Samsung galaxy S6 edge" - it's not mine, so I can't know the history that caused it - but I think it's related to a bad try of rooting.
when trying to flash a new stock firmware from Sammobile getting the same problem - even after wipe and wipe cache.
on recovery getting this messege on the bottom:
dm-verity vertification failed... need to check DRK first...
this is what I tried to do to fix it:
1) flashed newest stock - still no do.
2) tried to flash with smart switch - it did flash - but it didn't help - phone still in bootloop.
3) flashed S6-UniKernel_v6-0001-ODIN or S6-UniBase_BOG8_v2 - it did helped, the phone worked, but I lost the IMEI and needed a certificate to fix the IMEI, I did it and the phone works fine..... BUT I can't left it with a custom rom 'cause I want the original updates and the original stock rom.
4) tried to flash the repair firmware G925FXXU1AOCV (comes with 4 files CSC, AP, MODEM and BOOTLOADER) which is 5.0.1, so it fails (tried also with pit file) - didn't do.
5) last thing I'm willing to try - is to split a new firmware to CSC MODEM BOOTLOADER and AP by myself... the only problem is - I don't actually know how to do it.
another thing I've noticed on the download mode it is written:
Current Binary: samsung Official and System status: custom
I was wonder if someone can give me a clue what to do, and how to fix this problem.
thanks!

What country are you from? Are you sure the phone isn't on 5.1.1??
Download the firmware from sammobile of your own country or the nearest country/countries, put the device in Odin mode and try to flash that one through Odin "AP" Okay "IF IT FAILS" (copy the Odin log and paste it on this thread. If it succeeds LET US KNOW PLEASE.
Be sure of the Android version.. If that's impossible my safe bet is to flash it with a rom for 5.1.1
You shouldn't mess with the PIT files!

hey,
first of all, thanks for the replay!
If I flashed with smartswitch - then it should flash the newest rom and the one who fits for the device.
what I flashed in odin is: G925FXXU3COJ1_G925FOJK3COJ3_G925FXXU3COJ6_HOME.tar
which is Israeli firmware and 5.1.1

Okay, BUT when you ran Odin did it succeed or fail flashing the device?
If it failed what was displayed on Odin logs?
If it failed, Please re-flash your device again through Odin and whether it fails OR succeeds, COPY THE LOG AND PASTE IT HERE !
I need to see the logs, if you want help.

You mean this post? It isn't clear enough, if you want help answer the questions people ask otherwise no one can help you.
And look, we are not talking about the device but we are talking about ODIN! Does ODIN fail or succeed flashing?
IF ODIN SUCCEEDS WITH FLASHING, THEN TELL ME!

Im going through the same madness for over 2 weeks...
heres my thread with a lot of amazing people tring to help....
maybe something there will help and apply to u and get urs up an running
http://forum.xda-developers.com/galaxy-s6-edge/help/bricked-s6-edge-sm-g925f-help-please-t3286385
please let me know if you get any sort of fix as i think im having same sort of bootloader issue....

Hey Ice, i didn't get your reply on ur thread sorry.
Do you have the same UniKernel as described above?
Please give me all info you have about your device and the current condition of the device (please be clear about what you can do with the device now and how you get to a certain menu such as Recovery/OdiDLmode/Smartswitch/Bootloop*kind of bootloop.)
Hope to be of good help.

Hi thanks,
have no idea about unikernel and have not tried anything with unikernel,
read someting about this somewhere else too,, something about the kernel not even loading cud be a problem?
phone is a galaxy s6 edge SM-G925F
was working fine and apparently on hungarian XEH firmware but not sure if it was on 5.02 or 5.1.1 when 16 year old kid did something or the other with it to put into bricked state.
have no idea of its previous info or condition as it was handed to me in a bricked state
only thing i can do with device is get into download mode and flash via odin...
have never ever been able to get it into recovery mode ever !!!! not even after any successful flashing
I can flash many stock files either the single tar files or either the 4 part multifirmware files
Can do flash and emergency recovery firmware through samsung smartswitch
but no matter what flash if its odin stock firmware flash or samsung smartswitch flash have never seen recovery and always can never get past the white samsung galaxy edge 6 with powered by android in white at bottom too
after succesful flashes in odin cant get out of download mode if auto reboot is ticked, only way out is to hold vol down and power. or get back into download mode then vol down to cancel/restart,
phone just never gets past that white message screen, sometimes that message will splash across screen continuouly like its turning on and off...like some sort of bootloop.... depending how i try to power/boot the phone back up again
and then sometimes it will just stay on the screen forever lit up and frozen/hanging...
strange thing that is happening now if you look at the last few attempts of flashing the 4 part multi firmware file and ticking re-partition to fix the pit files...
once i turn phone off out of download mode.... i cant power the phone/boot it up using just the power on button.
normally i assume to start the phone or turn phone on all u would need to do is hold power button.
so if phone is powered down or turned off after flash, power button alone will not turn it back on, have to go back into download mode and restart from there
i hope any of all that makes any sense at all

Here is a question for you.
When the device is OFF and you plug it into your computer, does the device then jump to the Smart Switch screen?
Btw IMPORTANT when you say that you "flash" the device through odin are you referring to the pictures on your thread where the logg states that it failed on "nand write" and once on "hidden.img" or did it actually pass after the complete flashing of all the files "hidden.img" included?
Firstly need to try this; when the device is stuck in the bootloop you have to do this.
It shows you this type of screen (1st)
http://www.pocketpc.ch/attachments/...49759183-s6-edge-bootloop-20151210_155028.jpg
(does it say kernel isn't seandroid enforced?)
Then this 2nd screen shows up
http://zidroid.com/wp-content/uploads/2014/03/Galaxy-S5-Boot-Animation.png
RIGHT after the 2nd screen SAMSUNG LOGO disappears press volume UP, HOME and POWER you need to be VERY FAST.
Then once the (1st) screen pops up again, release the POWER then volume UP and HOME buttons.
Maybe it's possible that it'll jump into recovery, even if it does this is not the solution just a way to diagnose.
Don't worry we'll fix it!

If you have to flash it in any way to get it in a bootloop then the test isn't required! Don't do it.

This is what i gathered for you guys as a possible fix, it would work 100% if you guys didn't mess with EVERYTHING IN ODIN!
Because i have tested it myself several times.
READ EVERYTHING CLEARLY
4# When you mess with an s6 to the point that it does not turn on anymore and it only reacts until you plug it into a computer then it shows a screen "error occurred during update use Smart Switch..."
Well by that point Smart Switch mode partially takes over and you can only flash the device successfully in Smart Switch mode using Odin on the computer NOT Smart Switch.
(this knowledge will be useful later)
!!! PART 1 !!!
Here we go, follow this in detail.
STEP 1. You need to download the original Odin 3.10.6 from XDA here below:
http://forum.xda-developers.com/attachment.php?attachmentid=3109599&d=1420980613
STEP 2. Download the Kernel below:
http://mirror31.downloadandroidrom....nibase/S6-UniBase_BOG8_v2.tar?token=514002462
STEP 3. Open Odin on your computer as administrator.
STEP 4. Now connect your device to your computer.
STEP 5. Put your device/phone in Odin mode.
(volume down, home and power)
STEP 6. Make sure Odin has detected the device.
STEP 7. Load the Kernel in "AP" and wait 1 minute, then click START.
It should say PASS! However if it does not succeed, reboot the device and try it again in Smart Switch mode.
(It should actually pass the first try if these simple instructions are followed properly)
_____________________________________________
!!!PART 2!!!
STEP 1. Download this Firmware below:
http://www.sammobile.com/firmwares/download/62003/G925FXXU3QOKN_G925FVFG3QOKN_VDF/
STEP 2. Open Odin as administrator.
STEP 3. Connect your device to your computer.
STEP 4. Put your device/phone into Odin mode.
(volume down, home, power)
STEP 5. Make sure Odin has detected your device.
STEP 6. Load the Firmware in Odin "AP" and WAIT a few minutes UNTIL Odin is done reading the file. THEN CLICK on START and install the Firmware!
!!! IMPORTANT !!!
1st Possibility, if Odin shows "FAIL" "hidden.img" then that's a GOOD THING!
your phone is allmost fixed.
(Let me know if that happens.)
2nd Possibility, if Odin stops at "Nand Write" you must start over, unplug your device make sure it's OFF, then plug it back into the computer in order to boot the DEVICE into SMART SWITCH MODE and then follow the "STEPS 2,3,5,6" again!
DO NOT FOLLOW "STEP 4" Leave the device in SMART SWITCH MODE. (read above "4#")
HOWEVER
If Odin shows "PASS" then DO NOT UNPLUG the DEVICE! Go get yourself a coffee your device should be perfectly fixed!
Just unplug it AFTER A FEW MINUTES and try to switch it on, if it doesn't boot up? All you need to do is replug it into the computer and see if it boots up by itself (this does occur sometimes).
!!! LET US KNOW !!!
You can proceed rooting your device ask for help for a complete root guide for this specific device/model SM-G925F.
EDITED AND SIMPLIFIED.

I did flash that UniBase kernel and because of this I've lost the Imei number... I had to use Jtag box to recover the Imei.
so Beware when flashing this kernel.
I will try to flash the stock rom from sammobile... Hope it will help.

only problem is - the device stuck on the first logo (powered by android).
and on download mode it shows:

System status: custom
and on recovery it shows:
dm-verity vertification failed... need to check DRK first...

I did some research also
http://forum.gsmhosting.com/vbb/f77...drk-device-root-key-not-shoving-imei-1991601/
and
http://forum.gsmhosting.com/vbb/f684/dm-verity-verification-failed-1974767/
I'm not sure what is this rootkey issue, someone said that it is damaged, therefore it shows the dm verity vertification failure.

I also got the "dm verity vertification failure" today, but with me it happened because I was dumb enough to flash a G920I modem and bootloader on my G925F...
So it also bootlooped and everything, and then just like what you had, it asked me for Smart Switch. But then when I used Smart Switch on it, I got firmware from a totally different country than my own (think it was from Mexico or something), as I live in the Netherlands. And it even asked me for my phone's serial number before Smart Switch went on and flashed that firmware.
So I guess they only look at the CSC or something? Anyway, after that I got it into download mode and immediately flashed the newest correct firmware, and am happily flashing ROM's again Just download your own country's 5.1.1 firmware and you'll be alright, as long as you can get into download mode

yeah... already flashed the newest for my country.. it flashes well but still stuck on logo after.
from some reason after flashing, on DL mode it shows :
Current Binary: samsung Official
System status: custom
so the system status refuses to become official. even after using the smartswitch software.
I think maybe some of the partitions in the eMMC are corrupted.

I think that's because you've tripped knox (hence custom), but you do have official samsung firmware, (hence official).
Edit: Have you checked your kernel?

succesful flashes i mean passes, i can get many many stock files to flash and pass no problem now as wasnt the case when i first got the phone
It shows you this type of screen (1st)
http://www.pocketpc.ch/attachments/s...210_155028.jpg
thats the first screen i can never ever get past
(does it say kernel isn't seandroid enforced?) it doesnt say that... but previously when i was flashing twrp and booted tried booting the phone up it woud say recovery isnat seandroid enforcing, i dont get that no more as i am flashing stock firmwares
