I lost where you replied to what I said about the otg cable but you're halfway right.
Try this.
Download Flash_img. and extract it from the zip file to a location on your computer. We extracted it to the main C drive (not in any folder) and will use that in the next steps.
Copy the recovery image for your phone to a convenient location on your computer, preferably with a short path. We will be placing it on the C Drive directly (not in any folder) and using that in the next steps.
Note: The recovery image should have .img extension. If it is in a zip file, extract the .img file from it.
Enable USB debugging mode on your device from Menu > Settings > Applications > Development.
Connect your device to your computer via USB.
Open a Command Prompt window on your computer and enter the following commands:
adb push c:\flash_image /sdcard/
adb push c:\recovery.img /sdcard/
adb shell
su
mount -o remount, rw /system
cp /sdcard/flash_image /system/bin
cd /system/bin
chmod 777 flash_image
flash_image recovery /sdcard/recovery.img
This will first transfer flash_image and recovery.img to your phone. Then it will copy flash_image to the /system/bin folder of your Android device and make it executable. Finally, it will flash the custom recovery image to your device using flash_image.
Note that we used c:\flash_image and c:\recovery.img in the first two lines as we had these files extracted at the root of our C drive. If you extracted the files elsewhere, use the appropriate paths and if your recovery image has a different name, use the appropriate name.
Reboot your device once the process is finished and you’re done. You may exit adb and the Command Prompt window on your computer by entering ‘exit’ twice.

If you can get into download mode try opening cmd and
Fastboot flash recovery " then drag and drop the twrp.img that I just posted the link for here with out the quotations". It doesn't matter what you name it in this case. This is the easiest way to me.
