Try hard reset. press vol up+vol down and power until you get a message.then press power forbhard reset.if it won't work,kdz updater is the solution to get back to stock.

[Q] f240s stuck in download mode

Hey guys,
Just a few days ago I received my LG Optimus G PRO F240S. I did some tinkering around with it and when i restarted my phone it was stuck on boot logo and in the corner it it read "boot certification error" I attempted to fix this by using LG's Mobile support tool but it said cant connect to servers.
And now whenever i boot my phone up download mode pops up.
Any help would be appreciated!

[Q] Bricked G3

Hi everyone, new member. Recently my g3 got in a bootloop so i hard reset it. Everything seemed to work fine but after a short time the device used to get stuck and restart. I followed a guide how to revert back everything to stock but something went wrong and the device got stuck on MiniOS and then Reset Status 2.
i tried to fix it by flashing it with .kdz file but for some reason now when i turn it on it says: Secure booting error and the screen turns black and the led starts flashing red and blue.
I cannot access download mode cause it goes straight to the lg logo and black screen but u can access recovery mode. i already tried a hard reset but its no use as the device gets back to the black screen.
Any help would be immensely appreciated as this is my second g3 in 4 months and im tempted to throw it away.
Thanks and good day

Weird bootloop

I have a bootloop on my LG G4 H815, it constanlty turns off and on again on the LG logo screen. It sometimes works after flashing stock back onto it or using LG Bridge but then crashes and gets stuck in a loop again. So its not fully bootlooped but still is. Anybody know how to fix it as i really dont want to buy a new phone
Nand corruption. Use warranty
