I was able to locate the bootloader unlock zip file doing a search on XDA developers, however, I'm having trouble with flashing the recovery. I have the ME302KL drivers installed, loaded the bootloader unlock apk file, downloaded it and ran it which lead to my tablet being factory reset. Hold down the power button and Volume Down, which takes me to the fastboot screen. I have fastboot.exe, AdbWinApi.dll, and AdbWinUsbApi.dll, and the twrp-3.2.0-0-duma.img all in one folder. I enter the CMD prompt there and copy paste "fastboot flash recovery twrp-3.2.0-0-duma.img" followed by enter to run that prompt. It says:
sending 'recovery' (8978 KB)...
OKAY [ 0.286s]
writing 'recovery'...
OKAY [ 0.478s]
finished. total time: 0.766s
After doing this, nothing really changes as far as I can tell. I manually reset my tablet by holding onto the power button. When I hold onto the power button and volume up (or type in adb reboot recovery from CMD prompt), it shows the android on its back with the red triangle exclamation mark logo like this -

Any help please?
EDIT:
"for those having problems, i found this,

"Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typingfastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install." Thank you Diones from
