Hi, I bought a Samsung S6 Edge used.. It was previously rooted and the knox counter was tripped...
I'm having some serious issues with it. From apps/google services to crash. It was previously rooted so I flashed the stock firmware on the phone. Even when I setup the phone (language and google accounts) some services crash... I can't recieve OTA Updates anymore because the status is set to custom and Triangle away does not work on S6's. I can't replicate anything to make a certain app crash, it's just random.. I need your help because i tried everything I could..
Stuff I did:
Flashed stock firmware (5.0.2)
Flashed an Update (5.1.1)
Factory reset and cache reset in boot loader.

Hi and thank you for using XDA Assist
I suggest you to ask again here in order to get a resonable answer.
Good luck!
Hi,
I've one (big) problem that I can't fix.
I've been using Android 5.0.1 for more than 1 year as I didn't want to upgrade (it worked pretty well) and because I had the S6 rooted with PingPong root.
However, one month ago it started to run slowly, crashing apps, ... so I decided that, as I wanted to wipe the device, why not upgrade to MM (6.0.1)??, so I did.
I did a backup of all my data and EFS folder and downloaded a 6.0.1 ROM to flash it with ODIN. Everything went OK and finished flashing the rom, but when the S6 restarted it showed this in the recovery:
'dm-verity verificztion failed...
Need to check DRK first...'
And I cant boot.
I've tried some tips that are here and in other websites:
- I've flashed stock rom again
- I've flashed a stock rom without cache.img file.
- I Can't flash some files as I've R/L ON. (I've been trying to disable it for many months but I couldn't).
But the S6 doesn't boot...
Thank you!
What worked for me.
So this is my current issue, but i was able to resolve the issue you are having. so what i did was get the 5.1X OK7 (My phone is Verizon) firmware and flashed through ODIN 3.12.5, this flashed stock 5.1.1 in my phone and it worked good. however i have issue with my phone random restarts and power button not working in recovery or in rom. however i can go in and out of downloading mode or maintenance mode.

Thanks for your reply!
I tried to downgrade to 5.1.1 or 5.0.1 but I get an error.
(SW REV CHECK FAIL DEVICE 2 BINARY 1)
That happens when you don't have the right firmware you have.
You CANNOT downgrade to 5.1 or 5.0 since you are on 6.0. The bootloaders refuses to be overwritten.

I'm trying to flash another 6.0.1 ROM (a bit older), but I get 'CHECK FAIL. DEVICE: 4, BINARY:3'
I've read that DRK problems are related with EFS files, so... Can I restore EFS folder (I've a backup from Android 5.0.1) to solve?? I don't know how to restore it without booting into the sistem (and without custom recovery)
I am afraid that downgrade to 5.0.1 is not possible, at least I dont know anyone who succedeed in doing that.
If you were on systemless root, probably your Knox is still 0, check it in DL mode, if it is and you have the phone less that 3 yrs (1 yr warranty+2yrs factory warranty) best solution would be to ask in Samsung repair center if the factory warranty would be accepted (ofcourse dont mention flashing, just say you tried official update, and play dumb).
If not you can try custom kernel wich will bypass DRK, and prolly make the phone bootable, but there is no guarantee everything will work well (maybe it will, but mostly it doesnt, forget using Samsung pay, and KNOX tripped)
As for EFS, maybe I am wrong, but I think EFS contains IMEI and sn info, and DRK is something else.

Thank you for your reply!!
I had the device rooted, but with PingPong root, so Knox is still 0. However it shows that the system is "custom".
I'll try the warranty, they may not notice the "custom", just the knox.
I'm with the same problem when trying to flash stock BTU QA7..and only if i flashing cf_root my phone is booting.
Any idea? I don't care about the Knox..

If you are talking about DRK, the only way to fix it that I know of, other than hw replacement, is via 3rd party professional repair tool. (Octopus/Octoplus box)
If DRK is ok, phone boots normaly, if it is messed up, the only way of booting is with custom kernel which bypass DRK check.
You can check it in recovery, if messed up it will say DM verity failed on bottom of the screen.
Ok, i send my phone to fix, i will tell you what happened.

Thanks for your reply!!.
I took my S6 (925F) to a Samsung service center as you said. However, they told me that my S/N was incorrect (I bought a second-hand S6 edge, I think someone changed it) so they couldn't fix it.
Now I'm trying to use SmartSwitch to do a factory reset but it asks me for the S/N and I don't have the original one, just a S/N from a non edge S6 (920F). How can I do the factory reset without my S/N??? Can I use the serial number from another 925F??
Now I'm trying to find an engineering bootloader, to bypass the R/L and flash CF-AutoRoot, custom recovery.... but I only find it for 5.0.1 or... for galaxy S6 G925T, not F.
Finally, I managed to fix my S6 by myself!! (not really, but at least it boots...)
This is what I did:
- I found a factory binary for my S6 so I flashed it via ODIN
- I flashed a 6.0.1 ROM without hidden and without cache
Then it boots without any problems. However, now I can't get into recovery
I hope this will help someone
I've checked on my download mode screen and Knox isn't tripped and my device status is official.
However, today, after installing official Samsung software, Samsung health claims it can't run on a rooted device, which mine isn't. I have tried reinstalling it and factory resetting. I've tried installing the PHE firmware which it supposedly came with, but to no avail. What can I do?
Also, what is a foolproof way to know which specific firmware my phone came with?
Thank you.
hello all.
long time viewer first time posting..
Ive searched, downloaded, and even called Samsung Tech Support to no avail. After a week now this is my final attempt before the phone goes on Ebay..
I have a Samsung Galaxy On5 (SM-GT550T01) through MetroPCS. Acquired last week when I decided to trade a sibling phones. I had actually rooted the phone for them and it was working fine. switched SIM card out etc, theirs works fine mine isn't. Turns out they did a factory reset with root and somehow managed to even wipe the OS leaving me with just Twrp Recovery.. Ive locked up my fair share so first thought was smart switch the SN i found on Twrps terminal was not the original sn anymore? Searched here saw someone post a sn -tried it - it seemed ok until 100% then states an error use code in emergency recovery but does not give me a code.. eventually says cannot recognize anything, Ive tried ODIN, ADB, countless recovery firmware - same result,,,called support was transferred to "the techs" who said they wouldn't be able to force a new OS onto the phone...I find that very hard to believe...sorry for the rant....just wanting to know now if i waste anymore time or buy a new phone....as for knowledge on all this I would say between beginner and intermediate...lots of google/XDA/YouTube and I am usually able to accomplish something..this had me beat as well as awake at 346am...any help appreciated! Again
Samsung galaxy on5 g550t1 metro pcs
twrp 3.1.1
no OS
not everyone all at once now...
What happened with your Samsung oN5 GT5501
Im currently trying to root my samsung GT5501. Now I notice their is a GT550. Different model. I think the GT550 is the ON5 Pro. 16Gb of internal storage, but the one I'm guessing were both inquiring about has an internal storage of 8GB, correct?? Now hopefully were talkg bout the same phone. Now was it the GT5501 the phone u had rooted? If so, did u do it without a PC?? If so can you direct me to instructions or vids. Can't find any specifically for the GT5501. All the tutorials are for the GT550 model..... sorry I wasn't any help to you, but I hope you got it all sorted out...

The firmware that you are trying to flash is giving you the sw rev error because that firmware is an older/downgraded version than the version that is already on the phone. You have to flash the firmware that is the same as what is already on the device or a newer version, you can't flash an older version. Find the newest, most updated firmware that you can find for your specific model number.
Do a Google search for:
"Stock firmware for SM-G935FD"
Then find the newest available version that is made for your specific region/carrier.
