Brick after incorrect rom flash [LooperXB]

So i went to flash [ROM] Looper_XB but i made a mistake and flashed 5.0.2 when i needed to flash 5.1.1..Now i have made mistakes in past and would usually flash stock firmware in odin to my phone but this time it is not working. i downloaded stock firmware from here > LINKTOSTOCK. I get a error in Odin. i can go into download mode and into TWRP. I dont know what my next step is.. yes i know how to use a search bar.....i thought maybe i could flash the correct 5.1.1 Looper rom onto my phone through TWRP but i cant get my phone mounted to laptop to where it will let me transfer any files that way.. i can view all files but once i go to transfer the file over the phone will basically disconnect...In need of some help here guys.
Also was searching around and saw something about using kies , which i downloaded and installed but my phone wont connect. I only get the samsung galaxy screen and TWRP and Download mode like i mentioned

As a last resort you can always download either Samsung Kies or Samsung Smart Switch software and restore your device with the original firmware. You will need your model and serial number. You can get your s/n by booting into download mode and then pressing the home button.
Sometimes Kies will not work on the first couple of tries but it eventually should. If it still doesn't then try Smart Switch.
Once you have restored your device you can start from scratch.

WIFI Wont Turn On

I've been trying to flash a custom ROM on my Note 4 for about a day now and every ROM I flash the WIFI wont turn on I will do my best to list in full the steps I've taken to do everything.
Started by trying to use Heimdall Suite to flash TWRP twrp-3.0.2-0-tbltetmo.img but it failed to download my device's PIT file. After some searching I told to use ODIN in place of Heimdall Suite Downloaded ODIN Odin3 v3.12.3 used it to flash twrp-3.0.2-0-trltetmo.img.tar. This seamed to work I have TWRP installed now so far as I can tell.
I downloaded CMRemix (CMRemix_trltetmo_MM.6.0.1_r61.v17.8_20160820-112925.zip) and flashed it after doing a full wipe. It looked like it installed correctly but during the initial setup it fails to turn on wifi.

Cm 12 & Cm13 required stock 5.1.1 lillipop bootloader and modem
If you are on mm 6.0.1 the wifi wont turn on cuz modem & bl is not compatible.
I am having the same issue with wifi not turning on. How do I know which bootloader and modem are required? Where would I get these?

I wonder if someone could expand on how I could fix this? I'm still in my learning stages and I have to admit, sadly I don't know exactly how to tackle this one.
Edit:
I was able to solve this issue by reading this post http://forum.xda-developers.com/showpost.php?p=69480388&postcount=13835 and flashing the 2 files in the link provided.

Flash latest stock firmware in odin .
Once odin shows PASS go to stock recovery and do factory reset and wait 15 minutes to boot.

Tab S2 (SM-T817T) Bootloop

Hello every one!
I am having bootloop problems on my tab s2 SM-T817T. I tried to flash the firmware through odin using stock firmwares from Sammobile. I was able to flash the Android 6.0 firmware but when it booted, it became extremely slow. I tried to turn on wifi and it keeps turning off by itself. It is so slow I cannot even set up my google account. I tried to flash the 5.0 firmware but there was a rev check failture.
I tried to flash the android 6.0 firmware again and the bootloop problems comes back again. I was able to wipe the cache but I was unable to do a factory reset. There was an error message saying that there was an issue mounting the drive.
Can anyone please kindly help me? thank you!
