TWRP and USB-OTG

Hi there,
So I did something really stupid and I wiped my phone while in recover mode trying to install a new ROM. And now I'm stuck with a useless phone that can only go into TWRP and Firmware Update Mode.
I've tried every method to unbrick my phone, and have a previous thread on this forum trying to get help (http://forum.xda-developers.com/showthread.php?p=48914581#post48914581), but nothing is working.
My question now is I'm running TWRP 6.3.2.2, If I buy a USB OTG cable and put my rom files on a USB thumbdrive, can I then install the rom from the usb? If so, where in the filesystem does this usb storage show up?

I believe only TWRP 2.6.3.4 can support OTG (I've been happy with it).
I think you may have to ADB push the files from PC over while in recovery (may need to look around).

Bricked LG G2! Please help!

Ok so I was trying to install CM13, so i read something on a forum (I think XDA), and installed this zip that I downloaded from the website then installed the zip from my custom recovery, and then restarted, and I could boot into CM13, but then I lost my custom recovery! (TWRP). When I try to go to the factory reset screen when the phone is off, I select all the Yes delete data stuff, because that's how I got into my custom recovery, but now it says secure boot error, certification error, etc. and just boots into a black screen. So the only option that I am stuck with, is i figured how to get it into the firmware update mode (download mode), but no custom recovery, and when I connect it to the LG Mobile Support tool, It doesn't say it is connected, I have installed the drivers like 3 times, and my phone keeps connecting and disconnecting from my computer (I can hear the ding sound each time it disconnects randomly and connects randomly. I have no idea what to do. Am I out of luck? Pleeeeaseee help!!!!
LG model D803 Canadian version, was running 5.1 CM12 just fine before until i decided to update and this crap started happening

Check if you are able to access download mode.
If not, check if you can go to recovery.
If both fails, then follow this guide : http://forum.xda-developers.com/showthread.php?t=2582142

The battery. BTW you don't need the otg USB you can use adb command while on twrp.
Oh yea the twrp used many layer of locking you need to swap again and again

USB Device not recognized on Windows

I have a dilemma. This morning my usb was working fine but I needed to get back to stock and unrooted. I flashed the system.img from the NDR90X factory image and wiped my data (not userdata however because I didn't want to lose everything) the phone booted up just fine and operates fine, other then it doesn't mount on my pc anymore. fastboot and adb do not work for me either. I tried mounting on both windows and linux, I tried using another computer, and I have tried mounting through the recovery. none of these have worked. I cant try going back to complete stock because fastboot is not recognizing the device either. the phone still charges fine with no problems. But I still am getting the feeling that maybe the usb port has malfunction. I was hoping that maybe someone could help me with this problem and reaching a solution. I don't know if I can contact google about this problem because my device cannot be returned to completely stock.
I forgot to mention that after flashing the stock system.img I also flashed TWRP, and since then I am back on a custom rom to see if maybe that would fix my problem. However it still persists.
I have uploaded a picture showing what error message I am getting on windows.

Reinstall the USB drivers

Turns out it was the USB that doesn't work. When I got home I tried another USB that I have and it works fine.

Z17 Lite won't boot after v1.05 ROM update

Hello,
After rooting the system I tried to upgrade the stock firmware.
I probably did something wrong because now the device won't boot.
At startup it shows the "Nubia... Powered by android" screen and does not continue with the boot process.
I still have access to TWRP so I tried to wipe everything and to install the ROM from TWRP.
It looks as if the ROM is installed correctly, but it requires reboot and after reboot the same "Nubia... Powered by android" screen comes up.
I also tried the emergency recovery but that installs only from external sd card (that the Z17 lite does not have), or from OTG device. I connected a USB thumb drive with OTG cable but it doesn't recognize it
At this point I have no idea what else to do.
I'd be happy for any assistance.
TIA

UPDATE: I tried different USB drives. One of them mounted. I found that this one was formatted in FAT. Since this is a small 2Gb drive that cannot hold the ROM, I found another drive that was formatted in ExFAT that also loaded correctly.
I loaded the ROM as suggested and now the phone is working again.
My guess is that the phone can't read NTFS file format in emergency recovery mode.
