htc one not charging (No usb host mode)

So today i unplug my phone from my charger, then i wanted to transfer files via USB OTG. So i immediately plug in my usb otg and my pendrive(cuz pc cant detect my phone due to usb problem), sadly it wont work (got usb host mode). then i download latest elementalx kernel (18.0) and flashed it. after that, i immediately go charge my phone, nothing happened. no usb host mode bug, no landscape mode.
then, i entered fastboot while charging my phone, it only display fastboot instead of fastboot usb and its not charging. Tried reinstall rom (ARHD81.0) three time, one of them it will charge after boot, but NOT anymore after i entered fastboot. Tried wipe system and cache, still not charging. Only will charge when powered off and in recovery mode. Help! Some of my friend told me that my battery is dying, isit true?

Tried

Brisk and down then connect usb
None of these take me to the proper download mode screen. Can some please tell me what I am doing wrong.

I also getting message Connection problem or invalid MMI. How can I fix this

Click to expand...
Click to collapse
Hold vol down+bixby for a few seconds then connect usb to pc.
Kies only for old phone like note 3/S5. Newer phones need Smartswitch
I have tried many times and watched YouTube tutorials I cannot seem to get my phone into that mode. Maybe my phone is faulty.
Are you sure your phone is a genuine Samsung phone?
