Today I tried rooting my LG V20 H91820h following this guide: https://forum.xda-developers.com/v20/how-to/step-step-guide-lg-v20-h918-unlocking-t3808258
When I was following everything and flashing the downgrading firmware.... my pc crashed with it still flashing.
Now my LG V20 will only boot up to download mode without a device id or anything in the log box and only just "633A B50".
After trying to flash it again it only gives me errors and doesn't succeed.
I followed this guide while trying to fix it: https://forum.xda-developers.com/v20/how-to/guide-lg-v20-to-life-t3827732
Any help or fixes will be appreciated.
