If you have a computer use GT's guide to unbrick. http://androidcreations.weebly.com/lg-g-stylo-update.html

Why can"t you boot to recovery and restore your nandroid backup. If you are not rooted and have a custom recovery (twrp) just boot into stock recovery and factory reset. If you can't get into a recover then you will have to start over and use unbrick method.

So, I bricked my Stylo messing with that Magisk stuff to get Android Pay to work w/root.


I lost TWRP and bootloader. My Stylo has a finicky USB port and only certain USB cords work. I tried everything in my house and was almost surrendering. Then, I tried a brand new USB cord and it worked!

So, I got to download mode and used the LG Flash tool in GT's link above and got my phone back to stock. I even updated to 20c

What was notable is my bootloader was still unlocked. I thought flashing the kdz would lock the bootloader again but it is still unlocked.

I'm going to stay stock probably until I get a new phone.
