[Q] My Phone wont boot up! HELP

Problem SOLVED!
Thank you all!

Hi ClarkOwen, would you care to share what happened and how to solve it? My Optimus G won't boot with red flashing led.

What rom are you using?
I tried to boot into safemode by turning on with power button + volume down button and holding it till it boot up then I uninstalled framework and gravity box as i think they are preventing my phone to boot up and then I rebooted my phone and it worked
What exactly did you do with your phone? What caused it not to boot up anymore?

There are senarios where you do get to restoer your phone using kdz but then it still wont boot up with red led blinking which basically means the battery needs to be hardware reset - taken out of the phone which would require you to open up your phone which is difficult. Thats why I need to know first what happened which prevents your phone to boot up.

Thanks for your reply. I run stock ROM and was preparing for flashing with CM11. I installed ROM Manager and updated my clockmodwork recovery. Then I boot to recovery when this disaster began. The phone just wont boot.
I followed the instruction found in this forum to unbrick using kdz updater and LGNPST and yes I needed to disconnect the battery first. Open up the battery cover was difficult but I managed to to it. After numerous attempts I managed to complete the step for both kdz updater and LGNPST but that still wouldn't boot the phone. Not even into recovery. I could get to the download mode though.
The last successful attempt with KDZ updater (successful means completed steps) has caused my phone totally dead. Now it won't respond in anyway. No flashing led, nothing. I suspect the battery could be dead.
Is it true that we can't charge the battery when the phone is (soft)-bricked?
Anyone knows how to charge LG Optimus G battery in the case of emergency? Ie. not through the phone? I read post about charging using stripped-out USB cable but I don't know where is the +/- of the battery.

[Q] Please Help, Hard Bricked lg optimus g pro e988

The phone is showing black screen after i flashed exitrecovery.zip file since i got stuck into a recovery bootloop and right after when i pressed reboot button in twrp phone died. Have i got the phone hard bricked?? :crying:
What i have tried so far is pressing various keys combination and nothing is happening, tried to get into download mode but right after putting the usb cable connected with pc into phone it gives a notification sound but doesn't shows anything on phone screen :crying:
I also tried to flash the stock rom with lg flash tool 2014 with kdz file but it reaches to a point in the beginning and it gives an error message that the "phone isnt connected pull out the cable and retry" and after pressing retry few times it gets stuck at 60%
Please help, is there a way to get out of this :crying:

When something similar happened to my Galaxy S4, I charged it to 100% first. Then I tried flashing the stock image back to it twice. The first time did not seem as if it completed. Second time was the charm. I know the phones are different but the symptoms are identical.

Still stuck in LG logo bootloop after using LGUP

Hi, I have an LG G3 VS985 on 47a (according to LGUP) and I recently tried installing an OTA update that I have been putting off for a while. During the update I got an error that froze the updating process so I pulled the battery. After pulling the battery I can not get passed the LG logo in the beginning. The logo will show up, turn black for a few seconds, vibrate, then restart again. I tried downgrading using the TOT and KDZ methods but kept getting a no ks version error or some other type of problem. So then I decided to use the newest 48a KDZ file and LGUP to update/overwrite what I have installed right now. The process starts and the phone shows that the installation is working but when LGUP gets to the point where it has to restart the phone (about 80%), it just keeps bootlooping instead of going on with the installation. I tried clearing cache, factory resetting, and everything else I can think of. I read that the bootloader might be corrupted? If that is the case, how would I go about fixing it? Thanks in advance.
Edit: Another strange thing happens when I plug my phone into a charger from the off state. Instead of showing how much battery is charged, it just shows a loading circle on the battery picture then proceeds to restart into the loop (without me touching the power).

Exact same problem I'm having
1 difference my led light does not work . Is there a fix? Need help

no recovery, no rom lg logo just pops up and fades away

So i was unhappy with my rom so i tried flashing another rom on my lg g4 h815 which didn't work and i didn't seem to be able to install anything with twrp on my phone so i wanted to reinstall twrp which didn't work and now I have no recovery, and no rom on my phone and when i turn it on the lg logo appears and then i have a blackscreen, and then that repeats. the logo only appears for like half a second. when i try holding volume up and power the logo stays a bit longer, though my phone doesn't enter download mode. the LG bridge doesn't seem to recognize my phone even after installing driver, and the lg support tool gives me an error apparently but i can't read what it's saying, the error message is just blank. I'm grateful for any help i can get with this. thanks a lot in advance

Sudden death of G3

Hello i have Lg G3 D858HK went unresponsive after using facebook apps while listening to the music.
It completely unresponsive and i pull out the battery and turn it on.
Only blank screen with blue and red led sign. Is my motherboard problem?
I tried to boot into twrp and reflash the rom i used which is Fulmic 8.0 and
same problem blank screen.
I start digging into countless of thread like LG G3 Hard Brick Recovery
I managed to flash partition using extracted .tot from LGD858HKATv10d, still it won't boot.
I continue with LG flash tool 2014 on download mode with trial and error with the problem always stuck at 4% S/W upgrade
and keep continue to ask me to disconnect and reconnect the phone. Somehow i managed to flash firmware
using new firmware D858HK30b_00_0906.kdz.
I thought the problem is gone, now it stuck on bootloop and sometime with dead android guy with warning marks on his body.
I do factory reset still not working.
Is it i flash the wrong kdz file?
I have clueless right now as where to seek help. I don't know what is the actual problem
motherboard or software.
