My phone LG Quantum Wont pass the Lg logo please help
I can't find anything looking through google or any of the WP7 forums I read about a boot problem on the LG Quantum. Have you tried calling LG? I know you bought it from eBay, but they may be able to troubleshoot it and may have a way to do a hard reset without it booting all the way up.

Hi everybody!
I have Lg g2 D802 Baltics. Yesterday I tried to return to Stock KitKat via Lg mobile support tool and Flashtool, both of them didn't work, they just didn't find my phone in download mode. Then I decided to reroot and reinstall TWRP. The first was done and the second too, but unfortunately my phone restarted and got a Security error and LG logo and can't boot, just permanently restarts. I've already read a hundreds of articles like http://forum.xda-developers.com/showthread.php?t=2432476 . The method written here isn't working for me because the Flashtool just can't find my phone when trying to install a firmware. So, any program like Lg support tool and Flashtool don't find my phone, so I can't do anything with my phone to get it to work. I'm facing i real problem for me and i'm quite shocked. So, please, tell me what to do, how to fix my phone. I tried a lot of thins, nothing helped. What to do?
Hello guys, my name es Hernan and i´ve been using xda forum for at least 6 years with all the phones i had. But today i have a big problem with my LG and after hours of searching i couldnt find how to fix. My last hope is to post here and wish for help from you people.

DESCRIPTION OF THE PHONE BEFORE THE BRICK
LG G2 D806 with 5.0.1 lollipop working perfectly and rooted (with oneclickroot program). I tried to install TWRP using autorec (searching on internet i´ve found that D802 apk would work for D806 since this one doesn´t have his own autorec apk). After that the phone rebooted into fastboot mode. I used this (http://forum.xda-developers.com/lg-g2/general/mega-tut-how-to-fix-bricked-lg-g2-t3055033) guide to fix it but i didnt work, then i used d802 files to fix it because i thougt it would work.
CURRENT STATUS
If i turn the phone on it shows LG logo, after 2 seconds LG security error and after 2 seconds it turns off by itself.
if you plug the phone windows doesnt recognize it all (nothing at all literally) and it shows LG logo, then lg security error and reboots constantly nonstop. :crying:
no download mode
no recovery mode

hello guys, i wasnt able to answer because i was away from home for the new year.
After considering all posibilities and realizing that there was only one way to fix my phone i took courage and did the tutorial i've found and you gave me (http://forum.xda-developers.com/lg-g...brick-t2904404). After that, the phone revived from hell and right now its working perfectly. I can affirm LG G2 is UNBRICKABLE.
For anyone who will ever read this thread in the next months/years do not desperate if your phone is dead, your LG G2 will never be a brick due to flash mistakes.
Hey guys. I tried rooting my LG G4c but after rebootingen it seems that my phone is stuck in a loop, and i can't fix it.
What happens when i turn the phone on:
1. LG logo turn up
2. The following message appears:
[670] --------------------------------------
[670]
[670] Boot verification fail!!
[670] - cause : MISMATCH_SIG_LEN
[670]
[670] --------------------------------------
3. Phone reboots
Using the power button + volume down does NOT work anymore to start recovery mode (although starting the IMEI display still works).
I tried using LG UP to install the original firmware via USB but the device does not show up in the list (probably because the phone keeps rebooting itself). Some website also said to connect the phone with the pc, turn LG UP on, then put out the battery and put it back in to make it work, but that also didn't work.
Anyone know what i can try next? What method can i use to reinstall the firmware? And if it's not possible, does it cost much to repair and who should i ask?
Edit: It seems i can start "Factory data reset" but when this proces starts the phone restarts and continues the loop with the error message.
I also tried connecting the device with LG UP while the phone is stalled on the IMEI screen and the Factory data reset screen. This way the phone does note restart itself and it might appear in the device list of LG UP. But too bad it still didn't work.
I don't know if i'm reaching anyone who can help me, but even a answer from anyone saying that the problem is hard to deal with would already be very relieving I really can't find anything related to this problem on the internet and i'm noobish myself. I'm probably gonna visit a some phone shop down town in the next days because i really don't know what to do.

I had this problem too. I send it to LG and said the phone was unplugged during update process. They flashed it and I gave it to my mom. I have an S4 yet. Much better performance and rom support.
download mode

Can you get it into download mode?
Hello everyone! A guy from the forum told me to ask here for better advice. A few days ago i found my old lg e400 on a drawer and i was curious about its condition. I boot it up and everything is fine, exept for the fact that as soon as i entered my pin, the phone shut down due to low battery. Then, when i reboot, it somehow stuck on the lg logo (it does not even go to the flashing one) and thats it. It is not rooted, nor has cwm recovery installed or usb-debugging enabled. All i can do is see the lg logo, or boot into emergency mode. I tried recovery via lg support tool, but i get errors when it comes to writing data to device. kdz updater brings extract file error too. Please, help me. I want to fix it because it was a gift from my late girlfriend. Thank you in advance.
Never mind guys! After a lot of canibalizing with guides i found online, the phone finally works! If anyone from the moderators can delete this thread, beacause now its kind of non-functional. Thank you!

You will need to do some research, start on the LG website, I don't know the steps because my variant doesn't have a kdz available, believe you will need a pc, to connect the phone in download mode to flash

ive been able to load some kdz files onto my phone but none of them seem to fix the touch screen issue is there any chance iam using the wrong ones. can someone point me to correct 1 for LG V20 H990ds ame united arab emirates region. the stock rom pls for oero
this looks like a hardware problem to me, you might try reseating Lcd and digitizer connectors, but if not works maybe the screen needs replacement.
