Hello all!
I am back to see if anyone has any more ideas with what I can do to resurrect my LG G3. To recap, I tried to flash android 5.0 and I had forgotten to re flash the stock recovery prior to doing so. Long story short I completely botched the process and I am left with a LG G3 that can only access system recovery selection menu. When ever i try to just boot the phone by holding the power button, it shows the G3 boot image and then an error in the top left reads: "Boot certification verify".
From there, the phones screen turns off and the led flashes amber and blue until I pull the battery.
If I remember right, I need to find a way to re flash download mode but it has been several months since I tried to repair it..
Hope you guys can provide me with some input!
I linked a video I made of what happens when i try booting the phone below:

I had to do a warranty exchange through the insurance. It is not worth
The effort since we don't have fastboot. Got a brand new replacement.
Hope you can do what I did. Told them the truth that the phone
Would not boot up. Nothing else.

Totally would have done that had I not dropped my phone in water:silly:
Just pay the hundred and use the insurance, you can report it lost.
This way you can have spare parts.
You can also replace the motherboard. Sometimes you can get them
For 100.00 but I'm only seeing them for 150.00 on eBay.
Id like to hear that you can unbrick this phone but I doubt it with
No fastboot. Good luck.
Since it will boot cant you just usecthe lg flash tool thingamajiger and flash a .kdz

so, you can access recovery menu, does that mean you are in recovery?
if so, is it stock recovery or twrp?

You need Download mode to restore to stock via KDZ or TOT. He's lost Download mode, apparently.

Hi, i've a strange (but i hope common and resolvable) problem.
After all, i say that i searched through the forum (with the search function) but with the solution that i found and tried i didn't solve anything.
I start saying that i got a p500 with a broken sdcard reader board (it simply doesn't have a microsd 'cause doesn't recognize).
That phone some days ago just shut down and went stuck on the LG Logo.
I tried at first the hard reset (home+vlm down+pwr), nothing happens.
I tried then the recovery mode and try to update with lg updater, and didn't work, lg doesn't recognize the phone on the updater (but on the main screen of the BBc app does).
After some tries, (dumb tries, for example leaving it without battery for some hours), and searching, i did two ways:
-KDZ Firmware update way, selecting 3gqtc and diag on lg logo, or recovery (and recovery sc) on recovery screen, nothing done.
-LGMDP for installing fastboot and CWM and v20e. It completes the operation but nothing changes, the lg is still stuck on the lg logo.
The last thing that i noticed is that one time, powering on the phone, button's leds flashed about 4-5 times. but if i try to re-do the action, doesn't get anymore.
I would know if there is another way to exit from this stuck-screen.
I hope opened the topic on the right section.

When you say recovery and recovery sc, you mean EMERGENCY and CS_EMERGENCY, right?
So, you tried selecting these options while on the black menu of recovery (like the Clockworkmod one) or on the yellow screen saying Emergency Mode!! ?
In case you were on the recovery, try the following: remove the battery and, while holding the volume up and back keys, connect the phone to USB. After that, try using KDZ selecting EMERGENCY.
But in the case you were correctly on the emergency mode and just used the wrong words here, then I'm sorry but I don't know what else you could try to solve your problem (wait and see what other ideas people will come up with).
When you say recovery and recovery sc, you mean EMERGENCY and CS_EMERGENCY, right?

Yup, sry it's late night and i got confused with words.
I'm can go on the yellow screen and "EMERGENCY MODE" is texted on center.
And on KFC Used both modes of emergency (even diag).
I tried to do this without battery, but the result is the same. When it reboots stucks up on the lg logo. =(
Uh, i forgot to post the errors of kdz:

Hello. I'm new to the forum, and the issue that brought me here as had me fulling my hair out of the last three days.
I'll try my best to make this short as possible. I have (obviously) AT&T Lg Optimus G (E970) that was running 4.0.4. i rooted and unlocked it and flashed a cm 10.1 using TWRP. Yesterday tried to flash a zip for a transparent status bar mod. But the flash resulted in CM getting stuck on the splash screen. So i booted in TWRP recovery mode to restore from a recent backup. In the midst of wiping my rom and going to restore, i guess my phone died (which was weird because it had a substantial charge). Then it would no longer power on, and the only was i could get ANY response was by plugging it on the charger. All i get it the red indicator light. my phone will only turn on when plugged into the computer. from there the only two thing i can do is enter download mode and boot. and when i try to boot, i will get the lg logo for a moment and the the screen cuts out and goes back the the flashing red light.
so I trien the LGNPST method.
i downloaded the auto LGNPST and installed just fine. downloaded teenybin and lg stock bin. i've tried to flash both (put phone into download mode, select the dll and select the bin file). what happens is everything starts off fine, then when it gets to 67% the phone reboots, then goes back to the flashing red indicator light, and a message on LGNPST will pop up saying the phone has been disconnected, and to reconnect to continue. so i'll unplug the phone, plug it back in, and put it in download mode, and hit continue. LGNPST will say complete but the phone will still be just sitting in download mode. and if i unplug it, it's goes back to square one (red flashing indicator light)
EDIT: i was flashing the v11c stock bin. i just flashed the v20j bin and now we're boot looping while plugged in (lg logo for about 2 seconds, shut off, repeat) progress???
SO SO SORRY FOR THE LONG READ. Just trying to give as much info as possible hoping it helps.
My question is, is this a hard or a soft brick, and do i have any options left? after researching on here i'm hoping JTAG isn't my only option (I don't have the time or funds to go that route) and i saw someone mention taking it back to at&t, butIi don't think that would help me any since rooting the phone voids the warranty, correct?
I'd be eternally grateful for ANY advice. i'm at my wits end, and i've been google researching this for so long i'm starting not to even comprehend what i'm reading. PLEASE HELP!! And thank you so much in advance.

If it is hard bricked when connected to computer it will show up in device manager as QDUSB Device or something similar. You could try to do a factory reset with button combo, be sure phone is powered off then hold power and volume down until menu shows up.
You Can Also Try TeenyBin If Factory Reset Does Not Work

thanks for the reply guys. it looks like my phone is showing up in the device manager under ports as "LGE AndroidNet USB Serial Port (COM3)" is that a good sign? i'm going to try flashing teenybin again.

Yes, you are not dead in the water. Proceed, young grasshopper.

All the custom, unofficial 4.2.2 roms I found on XDA require that you be on the latest LG 4.1.2 OTA.
There are also links to stock rom and kernel so you don't have to mess with LGPT whatever. No need to do OTA etc, if you flash this.
http://forum.xda-developers.com/showthread.php?t=2219953
I also found TWRP to be far easier to install, which is installed by default I think with FreeGee. But you can find thread for the latest TWRP 2.6. TWRP makes flashing and wiping cache/dalvik super easy.
Ok, so i'm starting to think this is a battery issue as opposed to a hardware issue. i could still be wrong. I've flashed the stcok rom after stock rom. When i plug my phone into a computer usb port it LG logo boot loops (and this is the only way i can get to download mode), but when i plug it into the usb wall charger, i just get the red flashing light and no other response. when it's not plugged in i get nothing.It's still showing up as "LGE AndroidNet USB Serial Port" in my device manager and i can still get to dpownload mode just fine, so i know all isn't "according to what i've read and been told". So i'm running out of fixes. I did come accross a thread on here suggesting i unplug the battery and plug it back up. So i'll be getting the tools and praying that works.
I did also come across an interesting thread on another forum. They were saying how id you allowed your battery to drain all the way to true zero (which i think might be possible because my phone died in recovery mode), it wouldn't have enough juice to initiate and monitor the charging process. If this is the case, can the batter be brought back to life? a jump start or something (lol)? or will i have to just replace the battery?
THANK YOU SO MUCH FOR THE HELP SO FAR GUYS.
When you used lgnpst to go to 11c it boot looped because you tried to go backwards from cm. If you did a factory reset afterwards with button combo it should boot. Also can you get into recovery after flashing teenybin to do a reset and flash a ROM?

i did a factory reset a few times, but it still never booted. and whenever i LGNPST, when it hits 67% the phone reboots and just starts bootlooping (if i flash a stock rom) if i LGNPST teenybin, at 67% the phone will shut off and the flashing red light will just come up. and after each a message will say phone was unplugged or lost connection. after both instances ill plug it back up and put it in download mode again to finish and it will complete, but the phone will just be sitting there in download mode. and if i reboot.... bootloop city.
i cam across this thread that seems to detail my issue perfectly. so i'm going to attempt a teenybin flash one more time to tryt to get recovery mode (havent been able to get it at all), and if that doesn't work i'm going to do a battery pull..

and thanks to the tot link provided by zymphad above, i'm now running jb 4.1.2
THANK YOU GUYS :highfive:
I found LG's camera lacking, but 4.2 has an update for that, plus the camera mod, much improved I think.
Running RootBox great now with 124mhz idle, GPU downclocked to 200 and CPU undervolted to 85, stable and cool. I don't 3d game on phones.
Glad you fixed it, I just hope someone makes a high capacity internal battery for us since taking it apart isn't that difficult.

I'm using v40 of temasek unofficial cm11, Boefflea version 11 kernel.
while I was using my phone, the phone suddenly went into a reboot and started the boot-loop, even when I pull the battery out and put it back in it starts booting immediately and goes into the boot-loop , whenever I try to go into download mode or recovery mode, once or twice I will be able to reach it, but 3 seconds in, it restarts and goes into the boot loop again (I can't choose between restarting or going into download mode)
would a USB jig help me getting into the download mode or will it be 3 seconds in and restarts?
would a service center help me retain my data as I need them?
Thank you.
momentarily I've managed to be able to access download mode and the laptop started making a sound trying to identify the device, too bad the battery fell off (or the phone restarted) lol
anyways I still need help because I couldn't get into any of them
If the phone starts the moment a battery is inserted then usually the power button is stuck -try giving it a wiggle, or get it replaced.

yeah will do that once this gets fixed lol ..
for some awkward reason, I found out that once I pull out the battery I can use download mode
what should I download?
I tried flashing CWM but I get back to the bootloop ... should I install a newer bootloader?
No, bootloader is irrelevant to firmware. You would be best to flash a full stock rom with odin then factory reset and see if it will boot. I would suspect the power cycling may have caused partition problems if recovery got wiped.

which would mean I would lose all the data in the previous cm11 right?
I'm trying my best to flash a recovery but I think it got wiped for good.. I'm trying to flash it over and over again .. (I unplug the battery once I'm in download mode to prevent the sudden restart) .. before I flashed the CWM through odin I was able to go into a glimpse of a recovery mode, now I can't seem to see it at all...
is there a way to just copy the data (mostly pictures) through odin or adb with my phone current state?
Google says it might be possible

only through recovery mode or hoping your phone would suddenly connect after many boots lol
I don't think that will be my case .. oh well
as long as I can get my phone working again
going back to stock rom didn't fix the issue. can't access anything yet.
any help?
if anyone is reading this, I've been looking everywhere for a stock rom with pit file, I think that's the problem I'm facing since I have different bootloaders and different modes, somewhere around that I jacked my partitions and I think this would help putting it all back
I've found ones for android 4.1 but nothing of 4.3 .. since I came from 4.3 stock rom and then 4.4 kitkat temasek I think 4.1 won't help me at all
time to go to a service center I guess.
OK this is weird...
after I gave up I put my phone on a recover firmware that for some bizarre reason brought it back to life!!! I just put the phone back and left .. 5 hours later it was on and working.. I was able to access the phone for a brief moment.. but for some reason again I wasn't able to get the touch screen to work... I was able to raise the volume.. restart the phone.. but nothing on touch screen..
then it went back to the dead state...
any ideas?

Hello Xdma,
I have a rooted LG G3 D855 (D85520H to be exact). Recently I decided to try and downgrade the firmware from lollipop to Kitkat and failed uberly. For some reason my device had no download mode, and when I tried to put it in this mode, it would go straight to fastboot.
I decided to take matters into my own hands. I found out the only way to get back download mode was to flash the correct laf.img file to my phone. I have all the adb and fastboots installed on my computer. I thought life would also be easier to flash this buy getting a TWRP recovery. I tried using flashify for this. Unfortunately after flashing it I was forced to reflash to the stock recovery because it could never get into recovery mode . Instead the screen would go black and the led light would flash red and blue.
Just as I was losing it I then proceeded to do something utterly stupid. I erased the system img from my phone (as well as the laf but I have a backup copy) through fastboot.
I am now unable to get past the LG logo after turning it on. How would I go about fixing this? Feel free to call me as many names under the sun for the stupidity of my actions.
Btw I am an android nooby so be nice and talk in a language I can understand!
Thank you for any available advice!
So I rooted my HTC ONE S (villec2) today, and I wanted to flash a custom rom on it. I got a recovery (turned out to be a bad one, but it worked either way.... I noticed way too late it was made for HTC One M8) I got TWRP 2.7.1.0 and I got it working on my phone. I then backed up the system, and realized I messed up the recovery. In the meantime I got a CM 12.1 img on it and wiped the thing. The wipe removed the old Android system and the CM I downloaded was a bad download. If I go to recovery in the bootloader, it will just do the HTC white screen with "Entering Recovery" and the red warning logo but it won't get anywhere. It's just stuck there. So now, I'm stuck with a device that won't boot normally - just stuck on the white HTC screen, will boot into bootloader, and I want to know if there's a way of accessing the internal storage without being in the operating system. The worst thing is, there's no external SD Card, all just internal... Please god help me. I'm really stressing out about this since it's the only phone I have and if I lose it.... well I'm practically f-ed.... :crying: I know that I messed a few things up really badly and I'm not sure what state the phone is in.
Also just to add, the phone is barely loading up right now. I'm really scared since it's my only phone and it won't even boot normally right now. It's really acting strange, it was on 90% battery but now it might just be dead... i don't know.... someone please help
I honestly think I screwed it up.... All it does now is just a white flash / flicker when I hold the power button (both only power button and vol down) and that's it. I'm really disappointed right now but oh well.... Maybe just because the battery is not charged.... Also been looking around the other threads and looks like a lot of people had the same issue but with 0 replies...

I have no way of trying the stock rom. I cannot access the phone itself because I deleted the OS. There's a weird thing, that if I plug the USB to the computer, it does the connect windows sound but the phone's internal storage is still not accessible.... So as it turns out I can get to the freaking bootloader but then it just turns off with a white flicker a second later.... I have no clue what to do :crying:
try to hook your device with windows and hold the Volume Down and Power
to see if it can detect it

Alright. I slept through the night and now I'm here trying to resolve this again. Status now, is that when I try to boot it up, it just shows a white flicker and won't turn on. no matter if i try to boot in bootloader or normally. The device doesn't appear to be charging when I plug it in because it doesn't show the LED light for charging. I think it's hard bricked. I tried other threads, showing bright light to the proximity sensor, but nothing happened.
//edit// - My bootloader was unlocked, and I was on S-ON (HTC ONE S, S3 villec2) that might change on your phone and might make the process different
So I fixed it. I will leave the tutorial for anyone in the future that might be having the same issue. If you "locked yourself out" of your system, eg. no OS, and broken recovery just plug it into the computer, try somehow getting into bootloader, go into fastboot and plug the usb cable to your computer so you're in Fastboot USB. Then you can flash a recovery on the phone using a fastboot command. I believe it's fastboot flash recovery _filename_. Just google that, there'll be plenty. Then you have the recovery and you're back on track. After that you can get the rom you wanted. Just don't make my mistake, and check if your device is exactly the same as the files you're downloading for it. I messed up there . Anyway, good luck everyone!
t
yea
Happy to hear that u have fixed your phone add "solved " to the title and add a fast tutorial for help purpose
