Question A little help please

well I thought I read enough. I seemed to have missed something. First I toted to the update, no problems. Then rooted ok, no problems. The problem happen after I followed someones direction and install TWRP. That seemed to go OK. I booted into TWRP and did the WiFi hot spot hack-seemed OK. Then the problem sowed its ugly face. It restarted will not go past LG. I can get into TWRP. When I reboot into download mode the windows 8.1 and windows 7.0 will not see my phone.

Please is there anything I can do, please let me know.

UPDATE: I some how got it working with this help.
