lg g3 d722 bricked? - G3 Q&A, Help & Troubleshooting

I wanted to install lineage os on my lg g3s beat d722. I've rooted the phone and i was trying to get the twrp installed when strange thing started happening(restarts,crashes) and if that wasn't the only problem, my dad used the lg tool to fix it and made things worse and now i cant even hard reset the phone. The situation got even worse because now the phone opens and after a few minutes it restarts and tries to do a hard reset but a "security boot error occurred". I think it got bricked but im not sure. Plz help me

weird bootloop broblem

Hey!
two days ago, out of the blue, by device restarted it self, and started to to it every few minutes.
after that, it just stuck in bootloop tho it was able to turn on for few minutes once or twice,
I tried to recover to factory settings from the phone, re flash the latest version with LG bridge, and use the flashing tool to reflash the kdz.
it always goes back to booploop(I think)
download mode works and not crushing.
any ideas? I
G4 h815 twn
Unfortunately, the same thing's been happening to a lot of people lately. I'm getting bootloops on my G4 but it hasn't happened enough for it to be a problem. Once it becomes more of one, i'll send it in to LG under warranty. I would suggest you do the same too (LG warranty is 15 months from the month the phone was made - that info can found on the outside of the original box) Good luck!

ofc i did a factory reset before flashing the new rom
i will now try to flash another rom.. but I have no further ideas on how to fix this issue :/

LG G3 boot loop, any solution?

Hi all, I've had some issues with my G3 and have got to the point where I need the advice of wiser heads to try and fix the problem!
The phone seemingly died during an update a few weeks ago, but I was able to fix it using LG's tool and upgrading to Marshmallow. Then a few days ago with no warning the phone froze, and gets stuck in a bootloop at the LG screen, with the flashing LED. If I try to factory reset, I just end up with the Android Droid with a red triangle and I can't get any further. I've tried numerous guides I've found to try and reinstall the stock firmware, all without success. (I haven't tried accessing bootloader as I have download mode available). LG's own tool gets stuck at 4% when I try to recover, and I've tried the LG Flash Tool but get an error at 6% (LAF_READ_GPT_FAILED) using the 8974 dll. I've also tried the LGUP tool but that gets stuck at 6% (Error can't communicate with phone[Kilo Packet]. The phone was not rooted and is a 16GB UK version (model D855). I just seem to be going in circles now trying to find a solution, I suspect somewhere along the line I'm using the wrong combination of programs/TOT/DLL files so I could really do with someone pointing me in the right direction here!

Download mode doesnt work.

Hi guys, im having a big problem over here.I have European d855 g3, 32gb version.When i turn it on phone freezes on lg logo and restarts.I thought it is a soft brick so i tried everything to flash it to stock and fix it with all flash tools , and i had a errror like "MODEL INFORMATION CHECK FAIL"" that is with LG flash tool ,When i try to get into download mode phone stays there a while and just restarts, stock recovery is stuck on logo too.So i thought it was battery and i bought new one.Problem is still here.Then i tried on my friends battery too.Nothing helps. I think it is not a hard brick because it is still giving signals of life. Sorry for my bad English, but i desperately need help! :crying: :crying:
