Accidentally deleted my OS on Samsung Galaxy S7. Nothing works! - Samsung Galaxy S7 Questions and Answers

I have a rooted S7 with TWRP recovery on it and i recently deleted my OS by accident as i was just trying to reset my phone to factory settings. Now the only thing i can do is boot into recovery mode and download mode, or i can just get stuck at a boot loop.
I have googled and googled and seen so many ways to try and fix this issue but nothing has worked for me. Heres a list of the issues i have and what i've tried so far. [Using Windows 10]
Installing Odin (3.12.3) and stock Samsung firmware from here.
Installing the necessary USB drivers from here.
My PC wont recognize my samsung device in either modes (recovery/download) and Odin wont recognize my phone either, as well as i cant find anything under "Device Manager".
Tried using ADB to transfer files to my S7 but when i activate ADB in recovery mode it just loads for a couple of seconds until it displays an error with no explanation.
I even tried downloading ADB drivers and necessary tools i got from this guide.
I also tried wiping Dalvik cache and cache.
I have tried three different USB cables on all available USB slots on my desktop PC and the one USB slot in my Surface and nothing works.
I have tried rooting previous phones but I'm still new to this rooting thing and there's a lot i don*t understand. Perhaps i downloaded the wrong USB drivers, or maybe I'm just unlucky. I just really need some help to understand how to fix this. If it can't be fixed is it possible to remove all traces of rooting on my phone?

The phone needs to be in Download Mode to use ODIN
The only sign it is connected is a COM port lit up at the top of the ODIN window
Add the .MD5 ROM to AP and hit start

[Q] Bricked Phone - Help!

Hey guys,
I tried flashing stock JH7 after disabling lagfix. When I tried to reboot, I ended up in a boot loop and the phone kept getting stuck on the "AT&T World Phone" screen. I can access stock Samsung recovery and Download Mode, but, although I tried numerous methods, Odin3 doesn't recognize my phone in Download Mode. I also don't have any update.zip or backup on my phone that I can flash in stock recovery.
Is there any way I can fix my phone without Odin3? If not, how can I get Odin3 to work on my computer? I'm running Windows 7 HP x64 on my laptop, and I have adb installed, but can't access adb shell for some reason.
I searched numerous threads but couldn't come up with a solution. Please help!

Have you tried reinstalling your drivers?
My laptop won't recognize my phone anymore for the Android UMS drivers so I've been using my desktop to flash using Odin.
I've tried, but Odin only recognizes my phone in recovery mode and doesn't recognize it in download mode.
Fixed at last!
I finally fixed my phone! I found out that I was using the wrong USB drivers -_-
I installed the correct drivers, and voila, my phone was recognized by Odin3
Sorry for the n00b error

[Q] Samsung Galaxy 5 (GT-I5500) won't connect to PC!

I've tried a few other forums but haven't got any replies, I guess since the Galaxy 5 isn't such a popular device. I figured if there's anyone who can help me they will be here though.
I wanted to put CWM on it so I could get a CM7 port on. Unfortunately it's just about impossible for it to get detected on USB. I've installed Kies (and even the generic USB drivers found in the SDK). In 2 days I only got it to connect once, and then I went and bricked it.
The one time it finally connected I ran Odin and tried loading CWM onto it. It still hadn't finished after half an hour so I figured it ended with an error that was never displayed. So I unplugged it and as expected - brick! I can get into download (upgrade/firmware) mode so I think it can be fixed if I can get CWM on it (and just install the CM7 port I had originally intended to put on).
Problem is I cannot get the darn thing to connect! to my computer I've tried two separate PCs, one running Window 7 x64 and another running XP x32. Is there a a certain process of connecting things? I haven't ran across anyone making mention of one.
Has anyone else experienced USB problems like this with Samsung phones? Would it even be possible to flash CWM on after it's been bricked like this? When I boot (normally) all I get is an image showing a phone and a PC with and exclamation error connecting the two. Please help!
Try to look for stock firmware on the forum.xda-developers.com and flash via ODIN. You need to be able to put the phone into download mode, so maybe get an USB jig. That should do the trick. Odin has to recognize your phone. First of all right click on the ODIN executable and select "Run as administrator" on windows. Plug the phone in the DL mode and wait until it appears as active in Odin. Then flash the ROM and pit file. (Don't use ODIN one click). If ODIN does not recognize your phone try a different USB port or reinstall Kies. The Kies trick was which I used and it was able to recognize my phone.
Thanks, martin0176. I can still manage to get the phone into download mode - it's getting recognized by a PC that's the problem.
Could you tell me more about the pit file? I only have an ops file.
Try a different cable. I was having the same problem on the Samsung Continuum and it turned out that the cable was working for power, but not for data.

[Q] Samsung Galaxy S - cant flash

Hi there,
I've read every kind of threads here and no one works for me. I rooted my Samsung GT-I9000 and all worked well, then the phone started acting crazy, my root was gone and when I boot the phone I come to the usual screen where you enter pincode but after that the popup screens start, multiple popups saying that twlauncher crashed, media, acore etc.. so I cant get to the screen where I can enable usb debugging. I can enter the stock recovery and my PC can contact the phone, but when I press vol down + home + power so I get the download mode the PC cant find the phone, not in win7 or in Linux. I have tried every kind of driver there is for Samsung but no one works that make it possible for the PC to find the phone when it is in download mode, win7 list it under "unknown device" and NO driver at ALL works so win7 can reqonize the phone. I've tried installing Kies how many times I dont know and uninstalling, updated SDK, uninstalled every USB driver and even the hubs and installed them again, updated win7.. what can I do to flash the phone!?!? Because Odin, no matter old from new; cant find the phone in DL mode, same with linux. And in stock recovery, I wiped cache and data but the problem is still there when I enter the OS after enter my pin...
How can I flash my phone without PC finding the phone in DL mode and no USB debugging enabled? Or how to flash CWM so I can flash a ROM from SD? Please help!!
At first try another PC with Winsows or use another USB cable.
About recavery-try to find temperery recovery or cwm,that flash from recovery.

As I wrote, my desktop is under Linux and the laptop under Win7 and none can reach the phone, both computers can only detect the phone in Recovery mode, but the laptop under Win7 only detect the phone as offline, Linux on the other hand can reboot phone into recovery from recovery, to download mode and reboot normal. Already tried to use Ubuntu 13 Live and it cant detect the phone in DL mode either. And tried different cables also. And if I find a recovery or CWM, then what? Dont I need to get phone into DL mode to flash something?
But in Linux I've got a small breakthrough, Heimdall can detect the phone know, but fails to flsah anything. Maybe wrong files or something..? But anyhow, if Heimdall now can detect the phone and it couldnt before; know I just need the right files to flash.
Just find a friend who owns Windows desktop/ laptop, download stock from Sammobile, flash stock via Odin. If not, try Odin mobile...

[help] s6 stuck in boot loop after editing build.prop file

Okay so some of you might know that there is a ram management fix for the Samsung S6 by editing the build.prop file. I tried doing it and my phone went into a boot loop(it just repeatedly show the white text of SAMSUNG GALAXY S6). My phone is rooted by the ping pong method which doesn't trip knox. The last 2 things I want to do is go to a samsung store or flash a stock rom which wipes my data.
I saw a video that you can fix it by using adb. However, when i plug my phone in my pc while my phone was in recovery mode, the pc doesn't detect. But if my phone is in Download or just its boot loop mode, the pc detects but it often says "Your last device is not recognised or malfunctioned" or something like that. Yes I do have drivers installed including Kies3.
All I want to do is just to fix my s6 build.prop file without
1. Tripping the knox,
2.Not visiting the samsung store
3.Factory resetting my phone and flashing a new rom.
Please help. Thanks
*********EDIT***********
I found out that you can flash a zip file that restores the build prop file here:

It's one of the replies to the post.
But I'm an odin noob so... how do you flash it???
***********EDIT AGAIN*********************
Okay... soooo I'm stuck now. I can't even get my s6 to connect to my pc. It just says usb device not recognised.
I already tried:
-Redownloading samsung usb drivers.
-Installing Kies3
-Installing Smart Switch then clicking more and reinstalling usb drivers.
-Using different port.
-Using different wire.
-Blowing into port and phone port to clear debris.
Help :/

Flash TWRP in Download-Mode and then connect it to your pc. After doing that, you can use adb and restore your old build.prop
