Bootloop - ADB not detecting phone - Galaxy S6 Q&A, Help & Troubleshooting

Yesterday I tried installing the original ROM with Samsung Kies(currently rooted). Everything went fine until I had to go into Download Mode. The PC did not detect my phone. So I decided to stop the process and tried to turn on my phone. That's when the bootloop kicked in... At this point the only thing I'd done was going into download mode and going back out of it. Nothing was transferred yet.
I have TWRP installed and I can go into recovery mode, but can't do much in there. ADB on the PC is not detecting my phone, tried all the drivers I could find. I tried it on my laptop, thats where ADB was working fine a couple of weeks ago, same result.. The only thing that I can think of is that my USB settings is set to Charge Only. Is there a way to change this with the Terminal in Recovery mode?
For the record:
- ADB is not detecting my phone
- Kies is not detecting my phone
- Odin is nog detecting my phone

Stuck at downloading

So in attempt to find my way to cyanogenmod 7 today i managed to brick my phone using odin3 one click. i was able to get my phone back into download mode after reading a few tips. so my new problem is my computer saying "usb device not recogniced. one of the usb devices on this computer has malfunctioned'. i've tried reinstalling the samsung drivers for my captivate and that doesnt seem to fix the problem. Any ideas? And if i can get odin to recognize my phone, should i master clear everything before trying to flash it back to stock?
Re-install the drivers and try again. Be sure to have the ODIN 1 Click open before connecting your phone in download mode.
also try different USB ports. wouldn't be the first time a port caused a connection problem.

[Q] ODIN sees phone in recovery mode, but not in download or when booted regularly.

What the heck could cause it to see the phone in one mode but not the other two? I've tried removing all Samsung drivers, and Kies, and installing rebooting, and installing just the regular USB drivers. Same problem.. never had a problem with Odin before.. not sure what to make of this.

Trapped in Download Mode [Possible Brick]

Hi everybody, Yesterday my friend and i were trying to upgrade his Samsung Galaxy Core (GT-I8260L) from official stock jellybean 4.1.2 to kitkat 4.4.4 unnoficial. We rooted it succesfully, installed Super SU, and BusyBox. Then we downloaded a TWRP file to flash it through ODIN. the flash was succesfull but when the phone rebooted it got stuck at the download mode. It doesnt boot, and we can't acces the recovery by any means. it just turns the screen on and show the download mode screen (picture attached).
We have tried everything, but the thing is that the device isn't recogogniced by the pc (We've tried in a win 8.1 and win 7 pc, but had no luck.). It fails to install the right drivers. we've tried to download almost every samsung phone drivers, but none of them worked. ODIN also fails to recognize it.
we also tried Heimdall, but when we try to install the drivers it does recognize the phone as 'MSM7x27' for some reason.
We also have problems setting up the 'SAMSUNG Mobile USB CDC Composite Device Driver', failing to make it work every time we tried to configure it (Automatic Windows Driver Install or Downloading it manually).
I hope someone can at least guide us through the solution or suggest a way to fix it.
Thanks in advance

[Q] ADB help

Ok so i have an lg optimus ls970. It turns on freezes then turns off. So i want to put a new firmware on. Im using ADB. I put the phone in recovery mode then go to update using adb. My computer does not recognize the device. Ive tried installing and reinstalling google usb and lg drivers still nothing. The only time adb recognizes the device is when it is on. What do i do. I also tried adb reboot bootloader but all that does is reboot the phone.

[Completed] galaxy s3 soft brick? can boot into recovery but not into download mode

hello, I searched but cannot seem to find this situation.
Phone stops at first samsung logo that shows model no and goes no further.
SD card is formatted and there is nothing on it (no backups).
I can boot into recovery (not always), but not download mode. There is nothing available in recovery as card is formatted.
I normally use linux, but used odin in windows.
USB drivers are ok except mtp connection to phone via usb. Phone is recognized as Samsung Android device. I used developer usb drivers and not kies; Should I have used kies.
If someone could point me to a thread that'd be ideal for this situation, I'd appreciate it.
edit:
every once in a while I can log into download mode or recovery. Phone keeps restarting and I have to remove the battery to turn it off and then enter download or recovery.
I can't seem to get the windows drivers to work as the phone is in either booting or in download mode when installing drivers.
