Security Error: this device has been flashed with unauthorized software.... - Samsung Galaxy Tab S4 Questions & Answers

...and is locked. Call your mobile operator for additional support.
I have a Tab S4 (SM-T830) and a while back I tried to root it unsuccessfully. It still worked, but I could not get it to update. Today I tried to update through Smart Switch, and that didn't work as it required I get into recovery mode, but I couldn't since I had TWRP installed. So I went into developer options, and turned off OEM Unlock, the tablet informed me that it would do a factory reset. Now, I get the above message whenever I try to turn it on.
What's worse is I can still get to the download screen on the tablet, but whenever I try to flash the stock ROM with Odin (I've successfully used Odin many times in the past), it sits at the message 'Setup connection" for several minutes, then fails with the error "Can't open the serial (COM) port. I'm really at a loss what to do with this tablet, it seems to be bricked. I loved my Tab S, but this thing has been nothing but trouble.
If there's anyone that has any suggestions, I'd be very grateful.
Thanks!

[Q] Kies 3 Unsupported device alert

Does anyone else get an error with Kies 3? when I connect my Edge Kies gives me an error! I want to perform a device recovery via Kies that's my last hope. I tried to root my Edge and now I'm stuck with a bricked phone and yes I have tried Odin 3.10.6 and regular s6 Auto Root from Chainfire as well. nothing works for me, I've looked everywhere to find the G925t firmware but no luck again. I'm really screwed.:crying:
Same
I'm guessing kies wont recognize it til after 4/10 since technically nobody is supposed to have it yet. Just a guess though.

same issue here. Had to use smart switch which is not as efficient from my old galaxy to the new one. Transfer stopped and had to restart 2nd time which did seem to complete.
Helium is much better for transferring data to new phone..
Same issue here. New Galaxy S6 and Kies 3 won't allow it: Unsupported device alert. WFT?

Do the following: open Kies, click on tools, Firmware upgrade and initialisation, enter your model number and serial number and let it download the firmware, after an hour or so depending on your connection speed the firmware will be downloaded and your phone will reboot into recovery to install the firmware. done
Use Samsung Smart Switch instead. It has replaced Kies for the newer phones.
Here is my video showing it being used to flash Stock Firmware to the Edge.
http://forum.xda-developers.com/tmo...p/flash-stock-firmware-using-samsung-t3079176
Supersport, I have a SM-G900A (Galaxy S5 ATT) and Kies 3 and Smart Switch says it is an unsupported device. I got to the part to enter the model and serial and it comes up unsupported again. I tried a different USB cable and also tried Smart Switch on a Mac. The white USB3 Samsung cable does not allow the phone to be recognized by the Mac so I used an old USB2 cable and it hangs on "connecting to your device".
I tried downgrading to Android 4.4.2 so I could root it and it is in the "firmware encountered an issue" screen with the yellow triangle. Ack!

It sounds like the MAC had issues with installing the driver. I'm not positive if your model is supported by Smart Switch yet, but I would suggest using Smart Switch as KIES has stopped official support for most of the newer models. If it's not supported yet, it should be soon. They keep adding devices. When I got my S6 Edge, it took about a week for it to be supported, but that's when Smart Switch had just come out too. Wish I was more help.
Anyone else have success getting this model to flash???
Bootloop
I initially used odin to flash OI1 update, after a rom I was using caused problems and I got bootloop. It changed bootloader value to b:3 and I'm unable to downgrade now so I used smart switch which didn't recognize device so used emergency recovery and still bootloop. I have factory reset and wipe cache multiple times along with adb side load and individual flashes of bootloader, modem, kernel, flashed custom kernel and twrp to access fix permissions and to mount partitions with advanced wipe etc and still wont boot past logo. Also during one fix attempt phone said can't mount system.. Idk I'm not understanding where the problem is .everything says successful but I'm still in bootloop. Please help. I've spent hours everyday for the past week searching & trying different things that seem might help so open to any suggestions.
I seem to be having the same issue. Tried to manually update my phone via Odin but nothing has worked so far.... Now I just get an error on my phone that says
"An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
What am I missing here?? It's a Samsung phone, and it's been around for over a year (S6 Edge T-Mobile)...

If nothing else is working, you can try this for the T-Mobile S6 Edge. ONLY the T-Mobile S6 Edge is supported, so PLEASE verify it's the correct one.
https://mega.nz/#!H0hz2AQJ!iDzw_SwCL7qpJnZ8Y_8EDSrSgvAHK_hT93igXHOlm3A
It's a known working version of Odin, the Samsung Driver Package, and Firmware. Place your phone into Download Mode before using.
If any issues, let me know and we'll work through them.

No worries, I got it working! Thank you!
SOLUTION FOR ANYONE HAVING ISSUES STILL
1. Make sure you have Samsung Smart Switch Downloaded
2. Make sure Smart Switch is updated.
3. Click "more" across the top
4. Click "Emergency software recovery and initialization"
5. Click "Device initialization" across the top
6. In the model name box, type in exactly your model number. It is case sensitive. (for me, it was located on the back of my phone on the bottom named "SM-G925T)
7. It will then ask you for your serial number which can be found by holding POWER, HOME, and VOLUME DOWN
8. PROFIT$$$$$$$
Will this wipe the data like recorded audio and video files? This phone belongs to a friend with cancer and I'm trying to unload message he recorded for his family. I need to recover the data first and foremost and then getting the phone operation is secondary. I've got conflicting reports of what a firmware flash will do to recorded media files. I'm hoping the SDcard area will be unaffected but I need to know beyond a shadow of a doubt before I do anything.
Yes it will, it will behave like a factory reset. It will ask you to backup your storage content if it recognizes your phone you may be able to fix it.

[Q] Bricked my SM-G925T while attempting to root. PC doesn't detect it anymore.

My phone was on stock rom, 5.1.1, and I tried to root it using zedomax's guide (found on youtube here: /watch?v=G5HDG6caoog) but I ended up bricking it.
When attempting to flash the root kernel provided in that guide, Odin gave me a FAIL result, and after that I've been stuck in a blue screen with a message that says: "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
So I downloaded both Smart Switch and Kies 3.0 and both have unable to detect my device, and Odin as well.
Can anyone tell me how to proceed from here? I cannot even turn off my phone, with either holding the power button. Holding volume down, home, and power button resets the screen into the same error above
I tried 4 different cables on different USB ports on my laptop, the phone is still not getting recognized. The phone is still stuck on the same blue error screen.
Device manager looks like this:

update:
upon reinstalling Samsung USB drivers and rebooting the laptop, it's now recognized in the device manager and Odin, but not Smart Switch or Kies.
Try flashing the stock firmware from Samsung several times, you may get lucky and return to stock. If you do and need your phone in order to make/receive calls/messages, leave it stock, root is not safe for this phone anymore.

I managed to flash it back to stock firmware, however it has triggered the knox count by 1. It's working fine now.
So is it not possible to root this phone at this point?

S6 Edge+ (G928) t-mobile soft bricked after OTA upgrade to 6.0.1 while overseas HELP!

Hello, I managed to soft brick my phone while overseas and am writing this message at 2:00am in the morning (at least in this time zone) after two days of trying to fix it. Some background info--I'm usually based in the U.S., have a Samsung Galaxy S6 edge+ with service from T-mobile. Have never rooted or modified the phone in any way. I'm using a macbook pro laptop (running a windows virtual machine/vmware, on the mac) on this trip.
While on this current trip to Asia (currently in the Philippines) (much to my surprise it seems like the phone was getting 4G data here), I accidentally bumped the "yes" button on t-mobile's persistent OTA upgrade request box and the phone started a OTA upgrade, I assume to Android 6.0.1. I kept an eye on the phone as it went through various stages of progress in the upgrade. didn't see any error messages. It eventually restarted, got to the T-mobile screen, and got stuck there. That was two days ago. I've done quite a bit since that time to try to figure out what went wrong, searched all over online to find potential solutions. it goes without saying if there is any way possible i need to recover many important files on the device, so a reset is the option of last resort.
Long story short, seems like the farthest I can get on the phone is to Android Recovery mode, or the download screen. I installed the android tools and have "adb" working from the mac command line. Bad news is, it looks like I didn't have USB debugging mode activated on the phone, now I can't see any possible way to activate usb debug mode because the phone just won't boot past the t-mobile screen. I can get adb to detect the phone for a moment if I select "apply update from adb" on the recovery mode screen but that's about it, haven't been able to issue any other commands to the phone through adb other than detect and sideload.
tried to reload the android image...via command line adb sideload G928TUVU2DPD1 but get error messages about failure to verify (i think), anyways adb sideload wasn't happening. I installed Odin on my windows VM, attached the usb bridge from the mac to the windows vm and Odin was able to see the device. I was able to successfully push G928TUVU2DPD1 to the phone's download mode, both Odin and phone seemed happy about the file transfer, the phone went through a install process, restarted, with the exact same result as when the OTA update finished - phone stuck at the t-mobile screen after reboot.
I tried to load TWRP to the phone with hopes to run backups, and was actually able to transfer TWRP to the phone using Odin, yet TWRP wouldn't install -- the phone complained of the unauthorized binary. i guess the phone has to be rooted first or something else needs to be flashed to defeat the binary check, haven't tried that yet.
So I'm stuck with a soft bricked phone for now, yet instinct tells me with Odin working and talking to the phone, I should be able to install -something- that will get me back in business...that's why I'm posting this message, to ask for help as it seems like this group is the go to place for this type of specific info.
i am not at all familiar with custom android work yet have been active with tech stuff for the greater part of my life, plenty of coding and experience dating back years and have done dev work in most of the popular languages, very comfortable with command lines, log files and so forth...just never had a reason to mess around at a low level with my android phone until the past 48 hours, so i'm not really familiar. does anyone have any ideas? as a next step i'm thinking of trying to push a downgrade to the phone through Odin which I suppose would be Android 5.1.1 , although I haven't yet located binaries that feel exactly right for t-mobile and s6 edge+ ... sigh, this has been quite a time consuming way of learning the bricked phone recovery process..
:good:
thanks in advance for any ideas or help on this...it's quite disturbing to be on a business trip with no phone, and the past 6+ months worth of not backed up (gulp) data still sitting on the device (hopefully)..
here's some data from the Android Recovery screen:
6.0.1/MMB29K.G928TUVU2DPD1
samsung/zenltetmo/zenltetmo
was flipping through the recovery logs and i notice quite a few log entries about "couldn't find any tzdata when looking for localtime!" , I notice entries like "Starting recovery on Fri Jan 2 03:55:29 2015" -- i'm wondering if the phone is having trouble setting internal time and date which might be preventing it from booting...just a theory.
sorry for the long message, wanted to completely describe this fun scenario, just in case anyone has any ideas..thanks again
keep trying to load TWRP from the download screen on my phone...but get the "custom binary blocked by FTP lock" message. There's no way to change any settings on the phone as it still won't boot past the t-mobile screen..

Can you download Odin?
Sent from my SM-N910T using Tapatalk
yes i have installed Odin and it's working fine...I can push files to the phone in download mode and it works fine, but the Android images i have loaded so far all seem to result in the phone getting stuck at the t-mobile screen...it won't go past there
Did you ever get this figured out? My guess is it has something to do with not being connected to t-mobile home network. The fact you can get to download mode & Odin sees your phone should mean all hope is not lost yet on recovering your files and getting it working again.
Twrp isn't going to work unless you had root installed with the USB debugging & oem unlock option turned on in developer mode.
Maybe try asking in some of the other s6 forums. There's a lot of knowledgeable people here & I'm sure someone knows how to fix this.
Goodluck, I hope you get it figured out, I know how frustrating it can be.

D852 bricked, stuck on android with the trunk open, no recovery, no connection,

Hello I have been having recurring issues with the wifi so I have tried to install an older version of the firmware. Everything went well, until it rebooted. The progress bar android with the trunk open almost completely loaded, until it got stuck in that permanent state. If I try to boot into recovery, the same screen appears, there's a couple of yellow writings who flashes then disappear.
When using the LG Flash stool to flash the tot file, it begins, the connection establish, but then it says connection fail with device. Which is strange since the phone itself is receiving the software name information. I also tried the shorting pins method, without much success.
I've tried on many computers and also other versions of windows and I always end up with the communication fail with device error. Here's what is happening https://youtu.be/rnZISocgtJg
It's very annoying since the device is like new and I would really like to have it working again.

Bricked Galaxy Tab3 7.0 SM-T210, can't enter download or recovery modes

I have a Galaxy Tab3 7.0 SM-T210 that we've owned for a long time, but I now want to use it for more things and find it a little clunky and slow compared to our more up to date smart phones. So i wanted to flash with a newer version of Android, but the tablet now appears to be bricked showing the "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again" screen and it won't do anything else. It won't enter download mode or recovery mode.
I came across these instructions to take me from a stock tab, and upgrade to Android 9.0 theupgradeguide.com/2019/09/17/install-android-9-0-pie-on-samsung-galaxy-tab-3-7-0-lineageos-16-how-to-guide
I loaded TWRP successfully using Odin and was able to set up a Nandroid backup. I then moved on to part 5 to perform a factory reset of the device, which was successful. This is where it started to go wrong though! I chose the reboot option after the wipe, rather than as per the instructions going back to the TWRP main menu. The tab rebooted and would't get past the Samsung logo. It went back in to download mode when I tried, and then tried to flash with a stock version of KitKat Android. Odin recognised the tab connected, it accepted the .tar flash file, and the tab showed the progress bar showing the download happening. Then Odin failed after a few minutes, and then the firmware upgrade failure error message appeared.
After lots of internet searching I've tried the following:
1. Putting it in download mode, doesn't work!
2. Putting it in recovery mode, doesn't work!
3. Connecting it to Kies, device not recognised and latest version of Kies doesn't have the option to manually select your device to reload the firmware!
4. Tried using ADB, device isn't recognised!
So i'm at a loss what to do to fix it, can anyone help?!
I was just trying to do the same yesterday. It all went fine with backing up and wiping, but TWRP didnt accept the image I downloaded.
It is so sad to have a capable hardware limited due lack of manufacturer care (not even saying updates, because they updated the android version at the time, but lack of optimization and how my tablet became sluggish, gave me disgust of any samsung branded device).
Can't you get to TWRP screen anymore?
If you can get to Odin download mode, trying reflashing Odin (perhaps a different version).
