Galaxy S6 Edge - Cant install TWRP, Carrier Shows - AT&T Samsung Galaxy S6 Edge

Hello -
I've been a long time reader/lurker and have been able to resolve most issues reading and searching.
I have a G925A S6 Edge variant. It came to me with a blue screen stating "System Software Not Authorized by AT&T". I have downloaded various ODIN images and applied and I get the same results no matter what.
The phone requires resetting a few times to boot. When it finally boots, I receive several app crash errors. I have tried to install TWRP and it fails and gives a secure error in download mode.
I know the phone isnt unlocked and I cannot fine the OEM unlock setting anywhere in settings which is probably causing the issue.
Anyone have an idea?
Thanks

You not reading enough. Phone have lock bootloader and you can't unlock at all as of now. This mean you can't use any other recovery then stock.

Thanks.
I was asking about TWRP only because I cant get the phone to behave properly. No matter what version I use, I get constant force closes on tons of apps...
Ive tried all the below versions:
G925AUCS5DPJ1
G925AUCS6DQC1
G925AUCS6EQE1
G925AUCU1AOCE
G925AUCU6EQCF
Im currently on the Nougat version G925AUCS6EQE1.
After I flashed each version in ODIN, I had to force reboot a few times to get past dm-verify and "No command" errors. Eventually, I got it to boot. From then on out it boots properly.
One other oddity, is under "Service", it says KT twophone service" - in settings.
I have no idea what the previous owner did to get it locked up on the "System software not authorized" message, but the phone would do nothing until I ran ODIN.

No command it is normal. Just wait for phone to start. Then go to recovery and do factory reset.
BTW. Are you sure it is G925A model, just asking to be sure.

Yes - SM-G925A printed on back and shows on download mode screen.

Great. Try ODIN again and flash E1. This time when you see "No command " just wait and let boot all the way. Then restart in recovery and factory reset. Reboot and let us know what you got.

[Q] Samsung galaxy S vibrant stuck on "S" screen at boot

To start, I was using I9000XXJP2 firmware on an unlocked samsung I9000 from Bell. I installed a lagfix a few days ago and everything was working fine. The phone was really slow and freezing a lot today so I decided to restart. Ever since then, the phone is stuck on the Samsung S screen (not the one with the triangle). I can get into download mode just fine and i tried reflashing XXJP2 using odin back onto the phone. Odin does everything fine up until i see a blue 'reset' on odin and the phone is in recover mode with the options asking for me to restart the system etc. I restored to factory settings from there and even cleared the cache and restarted but it is still stuck on that "S" screen at startup. Odin only says "pass" once the phone is disconnected. So as of yet I haven't been able to flash a working ROM back on the phone. If you have any ideas as to which ROM i should try, if you could place a link with that, I would be very grateful.
I've had this problem myself a couple of times (just happened today in fact).
Boot into recovery mode (vol-up, home & power). Do you see any error messages in yellow under the menu?
I was unsuccessful at reflashing any of the Froyo firmwares so I reverted back to the last official 2.1 firmware from Bell JH2. Since I was coming from a 512 pit firmware, I didn't repartition or specify a pit file. This ended up working for me. I've since flashed to JK3 and am about to go back to JPU.
Reply:
I actually do see an error message E:can't mount /dev/block/mmcblk0p1, Can't mount SD card.
I should mention that Im using the unlocked bell phone on fido. Will i lose the unlock if i downgrade? Also, if you could point me to the site where i can download bell firmware, that would be awesome. I went to samfirmware.com and they dont have canadian versions there.
Unless one of the pros comes by and says otherwise, I understand that's the error indicating internal sdcard issues.
However... if the thing is dead, you can't hurt it more by trying some fixes
You can get the official and unofficial Bell firmwares from samfirmware.com, you just have to look in the US section. You want the firmwares starting with "i9000UG". Here's direct download links for you:
JH2 (official 2.1)
http://www.multiupload.com/ZNBT2RY5Y0
JK3 (unofficial 2.2)
http://www.multiupload.com/WTZGSKJGPF
JK4 (official 2.2)
I've heard people flashing this via CWM but I haven't see the files.
Also, I've seen references to people saying their phones begin working again after this error msg after they've left the battery hour for hours.
Let us know how things go.
Reply:
No go. When i flash to 2.1, it just shows the "S" screen and turns off. When i flash to 2.2, does the same thing as my first post. I still can get to the download screen through all of this so I hope its not messed up too bad.
I tried several times this afternoon before it worked including clearing data/cache.
Although, I had a different error message so you might be SOL in the end.
called samsung
So I called samsung this morning and they basically said they won't repair it because Bell handles repairs. Since I dont have a bell account, I can't get it repaired. I keep reading on forums that if you can get into the download mode, if you see the battery icon when you plug the phone in, its not totally bricked so i still have hope yet everything I've tried doesn't work. I tried to adb into the phone in recovery mode and it detects it but says I dont have permissions to push files onto the phone. If anyone can tell me what possibly went wrong and if it is fixable, how, that'd be awesome because right now this is a very expensive paperweight.

ROM Flashing Driving me Beserko

Hello All,
New to the forums here and I am going to jump right into it. PLEASE direct me in the right place.
I have a Verizon LG2 VS980. Android 5.0.2. After about 3 hours I was able to finally get it rooted.
My goal is to be able to flash ROMS to it. My carrier now is T-Mobile. Initially I was looking to flash the phone with a stick T-MO ROM I found. But I found another one I would like to try as well.
I downloaded TWRP and selected my phone and selected Verizon as the carrier and flash the recovery ROM which tells me it was successful.
The thing is, I can't perform a manual boot into recovery mode because it takes me to a screen and just gives me the option to factory reset.
I tried downloading multiple apps to boot into recovery mode and when the device reboots, I get a message that just says Fast Boot Mode and that's it. It just stays there till I power off and then on again. WTH is going on???? I am assuming when I am flashing the recovery in TWRP, even though it is telling me it was successful it isn't. This is becoming more difficult then it seems and after 5 hours of this, my brain is melting.

Please HELP! Note5 stuck in Download mode and blue screen due to FRP block

Hi guys! I've been looking for help in the site all day now and I've decided to ask for more specific help.
I have a Note5 SM-N920l, I bought it online, I believe it's Korean. It's factory unlocked or international, something like that. And was running the Android Nougat 7.
I successfully rooted it and also installed Magisk. It was working great but while trying to get Pokemon Go to work, another story, I tried switching different settings and I turned off the OEM unlock. From what I understand (I am a noob) that has to do with the FRP. I had turned it on to be able to flash stuff onto the phone and I turned it off again and I forgot to turn it on... and I turned off my phone.
I was stuck in the booting screen with the red letters on top that read "Custom binary blocked by FRP lock". I tried booting into my custom recovery but FRP doesn't allow that. I can get into Download mode but when I try to flash things in ODIN the FRP block comes up and doesn't allow anything. (Tried to flash the firmware)
After trying to flash some things I am stuck with a blue screen that says "An error has occurred while updating the device software. Use the emergency recovery function in the Smart Switch PC software." I downloaded said software and it can't find my S/N. So it has not helped me either. I also downloaded Kies but it is stuck in "Connecting".
I don't know what else to do. I don't mind losing all the data and personal files in my phone, I'd like to know if there is a way to factory reset it or wipe it or remove the FRP. I am desperate, this is my only phone and I really need it. I'd appreciate any help I can get.

Root not properly working, please help!

I have the dual sim Exynos version, model number SM-N950F/DS.
I followed this guide 100% as said:
https://www.youtube.com/watch?v=ygcDFTPT248
Root is not properly working. Unsure why. I rooted using Magisk. When checking the app, it has ticked both latest and installed version V16.4. When checking safety net option, both are ticked.
Adaway even after rebooting says ''rooted Android required'' . Root explorer not working also. The only thing I got working and only after rebooting it worked was Titanium backup. After rebooting I was prompted to give root access which obviously I did and it works fine.
However, other apps requiring root access do not prompt me to grant it root access and immediately says ''no root'' .
Any suggestions? Thanks.
Ps. I keep getting this annoying notificaiton on the taskbar saying ''Security notice. Unauthorised actions have been detected. Restart.'' . How do I get rid of this notification? I restarted twice yet it keeps popping up.
And now for no apparent reason I am stuck on the Samsung logo, phone is not booting up. The top left blue LED is flashing but the phone is not booting. Please help.
^ I managed to fix my device, like always I was running an older version of TWRP!! Happens every time with every phone regardless!
From one of the threads, I downloaded the very latest recovery and flashed it via ODIN. Voila! Installed one of the Note 8 roms and perfect. Everything working fine.
Why is it if using a slightly older recovery nothing works? I am unable to even format/wipe, install roms, nothing...

SM-t813 problem trying to load firmware

I was recently given a SM-T813. I cant get to the Recovery screen because i'm presented with the bright blue screen telling me there was a problem updating, and to connect to the Smart Switch to restore the tablet. I can go into download mode, but i've tried so many firmwares from Sammobil and they keep all failing. It usually fails after it gets to the System.ext4 portion using Odin. On the tablet after it fails, it tells me FAP is enabled and something about cannot load non-fap? Am I getting these errors because im trying to install the wrong firmwares or the wrong firmware versions? I'm not sure which version firmware it had previously. And last time i was able to finally get to the Recovery screen, it had
Android Recovery
MMB29M.T813XXU2APK6
samsung/gts210vewifixx/gts210vewifi
But I flashed it with some other firmware, which it took, but after reflashing again, now i'm getting the above blue screen and im not sure which version firmware it has now.
Is the tablet toast or do i still have options?
