[Completed] help with the Android phone samsung s3 Sph l710 T bootloader wrong possible brick hel

hi guys, so today I was Trying to download a new rom for my phone which is Samsung s3 SPH l710 T and I was thinking I was searching online if I had to unlock my bootloader and so at the end of all that I ended up not downloading the ROM. but as for the bootloader I used ez bootloader unlocker something like that and so I unlocked the bootloader but then I reLocked it again. and after that I powered off my phone only to find that when I powered it on again it wouldn't start ! so I searched online and then I figured out that most people say that if you unlock it the bootloader that it would go into a brick a Hard brick Or soft brick I don't know which one but whenever I try to turn on my phone at all.it's not doing anything no signs of life at all on the phone. I tried it all the key combinations for factory reset, download more, all that. but nothing happened. so my question is on my phone would it work if I bought a jig whatever its called and try to force it into download mode? or if I just took it into Samsung service repair and play dumb and say that I don't know why its not turning on all that. so what should I do and if I send it to Samsung repair would they like to try to figure out if he was rooted or not. oh I also just before I turned it off and never turn it back on again I also unrooted it with superuser the one the permanent unroot with one tap thingy. so it should be Unrooted. but I don't know like what I should do if I should use the jig or if I should send it to Samsung repair or what to do! anybody have any ideas please comment please help me cuz I really want to fix this phone. and I'm sorry for the bad grammar and all that cuz I was using Google Voice. so please try to help me Thanks.

[Q] Bootloop [need help]

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.

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!!!

Hi, I have the same problem with a S6 G920T. Were you able to solve the problem?

Rooting issue

Hi.
I have recently tried to root my Samsung A50(also patched "disable dm verify, multidisabler, and rmm state bypass") but it was an unsuccessful try. The reason was that my phone was not booting into the OS and was stuck on boot logo. After some research I found out a way of getting out of that kind of situation. The way was to just download a firmware and install it on my phone with help of Odin. After that my phone started to work again, I even checked if my phone is rooted and it was not. But when I tried to use the Secure Folder I was getting error messages saying something like this - "This device is rooted or something went wrong".
Can anyone please help me with this problem?
