What have you done before? A Simple reboot, OTA-update, tried to root, installed TWRP? Anyway... I've found a tutorial on YouTube:

LG Magna stuck in bootloop/bricked

So first of all a little bit of backstory: I tried using TWRP on my phone to install a supposed CM13 rom that actually ended up bricking my phone, but I had made a full backup beforehand in case something like this happened, so I restored the backup via TWRP and nothing, so I thought to myself I'll just wipe my phone and install a stock rom, and so I did, but nothing, the phone was stuck in a bootloop on first launch ( I left it on for about an hour just to make sure). So I used LG Flash Tool with a .dz stock rom for my phone but still nothing, I also tried the official LG tool but the result was the same. I have access to download mode, fastboot and can factory reset the phone, I tried factory resetting it but nothing. So I assume my phone is bricked, how do I unbrick it?
I'm using an LG Magna H502Y Dual-Sim and has an MT6582 chip
Cheers,
Kamefrede
Exactly the same problem here.
You solved that problem?

Edit 2:
Don't flash the MD version. And don't downgrade with this ROM. I bricked my H500f again. Heavy.

root 10.3.0 OP 6t ?

hello how can I root it ?
after i update it i lost my root.
Thanks a lot
If you lost the root I suppose you have updated and restarted the phone via OTA. If I am right so you can use the standard guide to root it again:

I've never had my phone freeze but a Google search yields a lot of suggestions on how to force restart a 6T.
