LG Lucky Lgl16c Does it have a recovery/download mode? Also Twrp recovery flash?

I've looked all over the internet and can't find if this phone has a recovery or a download mode. I've tried lots of button combos and nothing. I know for a fact that there's a factory reset mode (vol down/power hold vol down release power then press and hold power) but that's it. Also I kinda tried flashing a twrp on my phone but it didn't work tho my phone boots and works fine but i can't factory reset so was also wondering if someone could possibly make a twrp .img file for the lgl16c that'd be awesome. :p Trust me i'd do it myself if i had the stock rom but it's not my pc and i don't wanna mess anything up on it with the installing ubuntu stuff.. hehe :angel:

missing drm libraries in stock(china stable).rom, also in xiaomi.eu and in cm 13

Can`t play google play videos, can`t play magine tv etc. It drives me crazy. Is there anybody, who solve this on MI 5 128 gb? (or fix the unofficial cm 13 rom [20160521 Update] by coderstory here in xda forum)

Lockscreen not working, also "System UI isn't responding" and Settings app FC

Hey there. I hope this hasn't been addressed already, I wasn't able to find a thread that would help me.

I'm running stock 6.0, no root. A month ago, one day my MXP lockscreen started having some pretty terrible problems; it wouldn't respond, basically. Pulling down would end up with a frozen lock image, then I'd need to press the power button to switch it off, then press it again to get to the proper lockscreen, and that wouldn't work either. After trying about 200 times I would be able to unlock it, then I'd start having problems with the notification bar (wouldn't work/wouldn't get to quick toggles). I tried rebooting several times, but after a few seconds on the issue would start again. Somehow after a while it seemed to start working properly on its own.

Today the same thing is happening. Only this time it's persisting after four hours. I guessed I would just disable the lockscreen altogether, and that seemed to work for about ten minutes. Now I get the notification bar issue, random system UI not responding messages, app switcher issues, a sometimes-not-working home soft button, and when I try to set the lockscreen again it asks for my pin (which I'm not sure it should, being that I disabled the lock); when I type it in the security app crashes.

The issue persists on safe mode as well.
Any ideas? Thanks a lot in advance
