Samsung Galaxy S6 Live Demo converting to G920F problem please help :'( - General Questions and Answers

Hi....
It's about my Samsung Galaxy S6 live demo which i bought some 6 months ago. It was working fine as a G920F. I could make calls, use whatsapp everything.In short, it was a full featured galaxy s6. At that time time i was noob. I didn't know anything about rooting-flashing. I thought retailer has sold me just a rooted phone that's why my software is not updating. I went for custom upgrade, started with super user full unroot, nothing happened. I rebooted and at once device started boot loop and was stuck. I tried everything but nothing helped. I saw a forum
" https://forum.xda-developers.com/ga...er-thread-guides-firmwares-t3267738?nocache=1 "
It helped me in knowing it was a demo unit and guided to flash it to stock and then to g920 F but after doing everything whatever it said disabling retail mode updating software in stock demo firmware, I can't flash G920F rom. Whenever I flash via odin it passes but stucks on Samsung live demo screen and on opening recovery mode says "Dm-verity verification failed.. check drk first " and else there is nothing...I am stuck on logo screen :crying:
My s6 was on Android 5.0.2
Firmware was G920FXWU2B0G8
Please help! I am crying :'( I bought it expensive... :"( ... Please help....

DM verity verification failure happens when your bootloader detects that there have been modifications made to the device that it deems to be unsafe.
Your 2 options are:
1) find the correct original firmware to flash via Odin and hope it works.
Or
2) let Samsung repair or replace the device.

What could be the correct original firmware for a demo version?
Also the boot screen even after flashing shows same galaxy logo witha live demo unt written on it...
Is there a way to bypass dm-verity verification? Somehow block the bootloader from detecting modification?
Please help... :"(

No, there's no way to trick the bootloader.

[Completed] Need Help Fixing my Semi-Bricked Galaxy S5

EDIT: See bottom of post
Hello everyone, and thanks for taking the time to attempt to help me.
Earlier today, my T-Mobile Galaxy S5 updated to 5.1.1. I searched google and came across a few links on how to root my phone (G900T) - The one I ended up using was CF-AutoRoot
I used Odin 3.07, used the tar5 file from that site above where I downloaded the root, and attempted to root the phone. Odin says everything worked as planned ''passed'' was displayed with 0 fails. I waited about 20 minutes, but my phone never rebooted, it was stuck in a boot logo loop ' 'Samsung Galaxy S5 powered by Android'' or ''T-Mobile'' was displayed.
I tried going into recovery and reseting all data / factory wipe but that didn't help, and made it even worse. Now my phone says this when I try to turn it on: ''Firmware upgrade encountered an issue, Please select recovery mode in Kies and try again''
How do I go about getting back to stock firmware , that is rootable, so I can then proceed to install CyanogenMod?
EDIT: I used Kies and was able to get back to stock firmware and the phone turns on.
Can anyone recommend a reliable root for the G900T S5?

Hello and thank you for using XDA Assist.
It's good to hear that you managed to revive your phone. Many of us find it convenient to install a custom recovery such as TWRP which makes backing up and restoring, switching ROMs, and many such activities much easier. XDA happens to have an active and friendly area dedicated to the Samsung Galaxy S5, and specifically to the T-Mobile version at http://forum.xda-developers.com/tmobile-galaxy-s5. I suggest you search that area or simply post your question in the Q&A forum there at http://forum.xda-developers.com/tmobile-galaxy-s5/help where our experts will be most likely to be able to guide you.

galaxy s3 semi-bricked need help!

bought this second hand verizon galaxy s3 4.4.2, rooted it with towelroot, and flashed twrp using twrp manager and when i tried to boot into recovery, i had a warning sign that software has been tampered with and i should contact verizon for help, i tried to recover using a stock rom with odin but it fails each time, i did some researcch for many hour without success.
sometimes the screen tells me to use software repair assistant, i was able to download it but it never detected the phone, just sits there while phone is connected, btw drivers have been successfuly installed.
i tried kies, didn't work either.
i know now that it had to do with locked bootloader, but this is my first verizon phone.
please any help will be appreciated!
Edit and solved!!!

Bricked Device after flash TWRP recovery

Hi all,
I'm not new in XDA but i'm new in Samsung and yesterday i bricked my device. i own a Samsung Galaxy S8+ G955F
What i did was, first ticked OEM Unlock and USB Debugging in Developer options and then flashed the original TWRP recovery for Galaxy S8+.
After reboot the phone bootloop, i only can go to Download Mode and after that i trigger the Knox too.
If i try to flash an original Samsung rom i solve the problem?
Any help please?
Thx.
Solved by flashing a stock rom.
Sent from my Samsung Galaxy S8+ using XDA Labs
Reflash stock recovery.
Jtag dead phone to life and rewrite IMEI
First of all my phone is the s8+ G955fd, but I am sure that the people that helped me can help most Samsung owners with bricked phones.
My phone ended up being stuck on the first boot screen, I couldn't get into recovery or download mode. I installed TWRP and after that I lost my IMEI numbers( dual sim), so I tried to reflash stock and thats when i became bricked. I searched someone to help and found reference to the Fonefunshop in England. I sent it there and they said that the eMMC chip was bad. I searched for someone who could write to it or put a new one on the motherboard . I found A2Z cellular in Ottawa Canada. They used jtag to restore it to stock and they told me that the Fonefunshop had not opened the phone which is necessary to use jtag as they claimed, so avoid them.
The phone was now back doing everything it should except the IMEI's were null like before. I gave them the original IMEI's and the phone is working like new.
If your Samsung is bricked these guys can probably fix it and it won't cost much to find out.

Samsung SM-G930F

I bought a used samsung s7 Sm-G930F but after using the phone for some days i saw an update release so i decided to update it but after download the update it couldnt install it due to some error i dont know is talking of. So after some days to went off and it couldnt come on. So i decided to flash the firmware BTU on it through odin3 but after get PASS in odin3 it keeps gets stuck on SAMSUNG. I have also try factory reset wipe cache before even doing the firmware flash. Also i try downgrading to 7.0 and 6.0 but didnt work. Please help am guessing am missing something. I also notice something when even i boot the phone in recovery mode and plug to my system, my system recognise as SM-G930S, while at the back is written SM-G930F. Pls provide with any possible solution to this issue.
Used phones are often rebranded as other models to try increase resale value. If it says G930S in download mode then that's the phone you have. If you tried flashing G930F software you've probably soft bricked it.
You could try flashing again but using G930S software.
