LG V20 H918 wont boot up

[NJ_RAMS_FAN]

Hi all,

I was downgrading to root my lv v20 to older firmware (used lgup) and now my phone wont boot up. No LG logo. nothing... and no its not the battery. lol.. any ideas? I'm still under the 1yr warranty period so I might send it.. What's weird is that I used this method before without any issues..

what version were you at before trying to downgrade?

10j...

You didn't need to downgrade 10j -- it was rootable.

Something must have happened while the phone was flashing, and either the XBL or ABOOT didn't get written (LG UP erases before it writes), and now you have a brick that only LG can fix.

If you have a warranty with either your carrier, or the phone is still covered by LG, open an RMA. Unfortunately, there is no way to fix that for the average person anymore -- booting from SD card has been pulled.

You got bit by ARB (anti-rollback). 10p is ARB version 1, 10j is ARB version 0.
