[Q] Bootloop [need help] - Galaxy S6 Q&A, Help & Troubleshooting

Hi all,
I need some help with my S6. A few minutes ago my devices suddenly restarts ( I honosly don't Know why) and hangs in a bootloop. I see the Samsung splashscreen, then after a while the device reboots again and again. I did a factory reset, after this the same happens again. The only difference is that now the system tries to install some apps (I guess this are provider specific apps by Vodafone), but then its still rebooting. I don't have any idea what goes wrong.
Now I need some support how to get my Galaxy up and running again. What can I do?
The Device is on the original vodafone ROM, I did a root with pingpong yesterday.
Build-Number:LRX22G.G920FXXU1AODG

Just use Samsung Smart Switch to restore the orginal firmware. Or flash a orginal Samsung Firmware with Odin. Both options won't trigger knox.

Thanks, I have reflashed the stock rom using Odin.

[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!!!

Samsung Note 2 GT-N7100

My phone stuck on recovery mode.

PLEASE HELP ME.

To make Odin recognize your phone, install the appropriate drivers.
Hi everyone,
I have about 20 of these Note 2 phones all with MDM locks. I tried to flash through Odin and it passes okay the stock firmware flashing processes but still comes to the password MDM lock screen.
I then attempted to flash it again with the stock firmware but enabled the NAND erase option. This seems to be wiping the phone okay (I saw the Android logo and the phone flashing).
Now the phone is stuck on the Samsung logo. What should I do now, any suggestions?
Many thanks.
