SM-G939P locked due to flashing of unofficial software - Security Discussion

Rooted my S7 according to Idonne Apps instructions and while root was successful the phone would power on, and boot up only to shut down about a minute later. This will go on until the battery dies... While trying to boot into TWRP screen flashes and displays a security message to the effect of " this phone is locked due to the unofficial flashing is softwares. Contact your local provider. Costs may be incurred for the repairs." That's not
verbatim, but it's pretty close. Upon attempting to enter recovery the screen flashes and both " recovery booting......" and download mode info BOTH appear in top left corner. Any help guys? I've been practicing and after I get this one back up, I've got a SM-G920P, and a SM-G928T, one rooted one not, that I also need help with. This is getting to be a pretty expensive hobby! Have many other phones to work with too!

Strange Rom Manager/Clockwork Mod problems

I have a rooted Verizon Wireless Galaxy S3, for reference. So today I decided to attempt to install Cyanogenmod and searched for something to install it on my phone. I found Rom Manager on the Play Store and installed it, and went into it. I installed Clockworkmod and flashed it, and everything went reasonably well until I rebooted my phone. At this point, it automatically booted into Recovery Mode, or at least tried to. What it really did was display the screen with the Samsung logo and "RECOVERY BOOTING....." at the top in blue letters. Then, it shows a screen with a yellow warning triangle, which gave me the "System Software not authorized by Verizon Wireless has been found on your phone" message, saying "SECURE FAIL:KERNEL" at the top. Now, after a bit of searching, I had found that I should flash a factory image, so I connected my phone to my computer, and that's when the strange stuff began. First, my phone started vibrating approximately once every second for a short amount of time(about 0.1 second) and my computer wasn't detecting it. When I tried to turn my phone on, it just displayed the normal first boot screen and then nothing else happened, and it went back to a black screen.
I've looked all over the place, but I can't find anyone that has encountered my problems and I have no idea how to proceed.

Were you on either of the locked bootloaders of 4.3 or 4.4.2? If so your issues lies there to begin with. No custom recovery other than safestrap will work with the locked bootloaders. Your lucky you didn't hard brick it

Stuck in "Warning Bootlaoder is Unlocked" Loop and Need Help

I have looked at multiple guides on this and other sites, googled and tried stuff and I cannot resolve this problem. Hopefully I am posting in the right place.
I took the jump and unlocked the bootloader on my Moto G first generation, XT1034 successfully. I flashed TWRP 2.8.60.xt1034.zip with adb and this was successful. Then I flashed Super SU 4.6 Update and that was successful. I got into trouble I guess when I tried to flash Cyanogenmod 12.1 nightly. I used TWRP to flash via install. The flash had an error, which unfortunately I didn't write down. I believe it was something to do with a partition. However, it looked like the flash failed. At this point and for hours I have been trying to fix the "Warning Bootloader Unlocked Loop I am stuck in.
I have been able to get into the phone and flash via adb commands. I've tried several commands suggest to fix this that I have found in forums. I have tried flashing several recoveries including an older TWRP per the method in this thread, a clockworkmod - and the original 2.8.6.0.xt1034. When I get into the phone bootloader which is available, I have not been able to access any options in recovery. Pushing the power button on recovery leads to a blank screen sometimes followed by a recovery starting or a Motorola Logo starting up and a couple times a recovery. TWRP has started a couple times, but never gets past the intro screen, where it locks up. clockworkmod (clockworkmod-6.0.4.7-falcon.img started once after flashing through adb and gave me flash options. I tried to sideload, didn't understand, went back and the recovery locked up. These recoveries no longer load at all.
Through all of this the "Warning Bootloader Unlocked" logo screen comes up after plugging into the computer (Windows 8.1).
Example, I open the phone bootloader by waiting for the phone screen to go from the "Warning Bootloader Unlocked" screen to blank - it cycles from logo to blank. If I'm quick the phone and hard boot the phone will boot into bootloader. I connect to the laptop through USB. When I toggle to recovery and hit the power button the screen goes blank, the Motorola Logo pops up, goes blank and then the "Warning Bootloader Unlocked" appears. The Laptop then seems to connect and disconnect as the Warning screen comes on and turns off.
The factory selection just goes to a blank screen.
I would really appreciate some advice on how to get the phone back to a state in which I can work with it and try again. It is very difficult wading through all of the information out there. I've learned a lot through this issue, but can't take it any further.
Thanks, Jeff
Solved - Stuck in "Warning Bootloader Is Unlocked" Loop
This resolution took many hours to figure out, but I finally got there with this guide - http://forum.xda-developers.com/showthread.php?t=2542219, this thread - http://forum.xda-developers.com/showthread.php?p=54855457#post54855457 and this thread - http://forum.xda-developers.com/gen...e-firmware-t3042687/post59139823#post59139823.
I tried RSD Lite on different computers and USB cables I could not get the device recognized. So I ended up with the MfastbootV2 method to reload stock firmware, which I found on the firmware thread above - this was big, as my phone is with Wind Mobile in Canada and the link is the right one. The only thing I picked up from a different website was to use a computer with USB 2 ports. This is what I did, but I don't know one way or the other if USB 2 was needed. .
Can't thank you hard working guys enough for the time you take to put these threads together. I'm back up and running. As a bonus, after a big clean up in the process, my phone is running fast again.
Thanks everyone.

Samsung Galaxy S6 (sprint variant) failed firmware flash FAC LOCK

Let me start by addressing I know this isn't the sprint thread but there's a lot more development here which equals more help. Plus this issue seems to be able to happen to any variant.
Second, this isn't my device I'm trying to see if it can be fixed for a friend. I'm not that familiar with Samsung devices but I have been able to get them working in the past via Odin or kies but this time I need some help.
So this is what's going on, my friend recently rooted his S6(SM-920P) not sure which method he used (don't think it matters at this stage) and was on stock rom (LP5.0.2) with xposed framework installed. He hadn't changed the kernel AFAIK oh but I did install TWRP for him and everything was working. Long story short he woke up a couple days ago to his phone being unable to turn back on. I told him how to get to download mode and I asked him what did it say on the top left corner it said something like "system binary not SEandroid locked" underneath that it said fac lock
So I had him give me the phone thinking somehow it did a OTA update while he was asleep or something either way I was confident using Odin to flash the firmware would solve the issue. Had the firmware finished flashing I'm confident it would have but halfway through Odin simply froze on installing system. I figured its just gonna take a while 45 mins later it was still stuck at the same spot.
Not really thinking about it I figured I will just reboot the phone back into download mode restart the process it should be fine. Not a good idea. Now all I get is a green screen saying to access the smart switch emergency recovery system. But it gets better.
My computer isn't recognizing the device now. I installed smart switch software and it's not recognizing it. I even installed Kies and it's not recognizing either.
Is his phone toast or what? I tried emergency system recovery but I need the S/N of his phone to possibly get this thing working again, but it boot into anything anymore except the screen that says Samsung switch...
PLEASE HELP ME if it's bricked it's bricked I get that but if there's a way to figure out what to do I'm all ears. Thanks in advance

FastBoot loop

I was having issues with my Motorola Photon Q LTE with the Stock ROM (it has bootloader unlocked and Rooted), but the problem was, when running apps that play video, they wouldn't work (it would just show a white screen with a film icon). Other phones work, just the Motorola Photon Q LTE was having issues with it. So, I figured i'd try another ROM....I had one problem after another with getting ROMs to work. Carbon ROM would install but would force close FaceBook (which is needed), another ROM gave an encryption error. I went between 2 or 3 recoveries and then found someone that said they had a "stock JB" ROM....I was tired and frustrated and wound up just clicking things b/c at this point, I was ready to toss the phone on the ground so hard that it would make it's way to the center of the earth! But, now i'm stuck on the FastBoot screen with it saying "Battery Low" so I can't flash a recovery onto it again. The battery was at 70% when I was in TWRP before that happened....now I can't get even get into Recovery or anything...
Okay, I think I got it fixed now......I managed to get it to take a charge. I had to plug it in, let it get to FastBoot and then push the Power Button....NOT hold it...just push it and it would turn the display off and start charging....its at TWRP now and installing a ROM...HOPEFULLY I can get passed the "Encryption Error" issue...

Need help after failed rom install

I've had some previous experience with custom roms on my old Nexus 6P and thought I would try the same for my mate 9. Unfortunately I've discovered the Mate 9 is not as easy to install custom roms as I thought.
I've tried several things throughout the day and I feel I've accidently overwritten things I shouldn't have but can't remember everything I've done.
It is an Optus branded phone so I believe at the start of the day I had some version of L09C34. I currently have an unlocked boot loader and TWRP installed and would like to flash back to the stock firmware, but seem to be unable to do so. The boot loader is unlocked and when I try flashing extracted parts from fastboot, the phone will reboot, reboot again and sit at erecovery. Unfortunately while I can connect to wifi, no packages are found for recovery.
Additionally I now get this lovely colourful screen in lieu of the logo on initial boot.
Any help would be appreciated.
Okay, so I've managed to unbrick it and install a version of L09C432 and get it working again - thank you to various threads on XDA. I think what I noticed was that someone else had tried the C432 firmware on a C33 model and it worked. Without being able to get hold of the C34 firmware, I tried to flash nougat originally and it worked.
This morning, I've noticed I still have an issue where the touchscreen won't work when the phone is cold (i.e I can't click anything and can't turn alarms off). If I reboot the phone to recovery it's fine, so it leads me to believe its an OS thing. Also, if I give it a few minutes in my pocket, or holding my palm on the screen it then responds. This is the issue I tried to resolve by resetting and trying a different rom but seems I haven't been successful.
Finally, when I first turn the phone on and the screen lights up I see a green background with one blue and one red box. Any ideas what I have messed up there and how to fix it? I'm not too concerned, but it would be a nicety.
Just providing updates in case anyone comes a long with similar issues.
I have now fixed the strange coloured screen on initial power on. I've found the oeminfo for the C432 firmware on another XDA thread and took a backup of what was currently there, restored the C432 version and rebooted. I was presented with the eRecovery and no TWRP. Quick check in fastboot mode showed the phone relocked. I unlocked it again and it booted no issues, however was unsure if the custom rom was still installed as I was presented with the option of an OTA update. Initially my sim card was not recognised, so I had to remove and reinstall it but so far so good.
I've just reflashed my custom rom and will see how I go.
The only potential issue I have outstanding is my touchscreen not working either first thing in the morning, or when the phone is cold - i.e I've gone to the gym and left it sitting in the locker for 2 hours and I can't use the touchscreen when I come back. I can unlock it fine with the finger print reader and the phsyical buttons respond but touches on the screen won't. If the phone is left alone for a few minutes the screen shuts off and turns back on approx every 5 seconds until it becomes responsive. Has anyone seen anything like this before? My googling hasn't lead me to anything helpful.
