I have a E988 indian version which is stuck at boot with the "secure booting error cause : Boot certification verify",
I can get only into download mode and no recovery or can not boot into OS,
Earlier when i was in the situation i could get into download mode and use LG support tool to flash stock, But now i am getting battery low error..
My question is "Is there any way to recharge the phone if stuck at secure booting error or in download mode ?"
I tried offline KDZ flashing also but there also i was getting battery low error.
Thanks
If you can get to recovery. Mine charges while in recovery.

Try a factory reset by holding power and volume down at the same time. Press power button to confirm reset. If you do this, sometimes it will reboot you in to recovery, if not try it again and this time manually enter recovery.

If i try to factory reset it initially asks for do you want to go ahead with factory reset and after i confirm the same old error of secure booting comes in... (factory reset does not happen), And i can not go into recovery mode directly using the volume up and power button...

I hate that stupid low battery message. It's so dumb that they do not allow you to continue at your own risk. I have also had this problem going from AOSP back to stock. The only safe way to do it is using LG Flash tools first, then flash one of those stock zipped roms. Now it is too late for that. Do they sell your handset in the country you live in? If so, they can fix it in store in most cases. For me, they don't sell this phone in my country, I was just lucky enough to be able to continually try to factory reset and then my phone randomly booted in to recovery (don't know why or how, it just did). After that, I flashed lockified TWRP and CM11 again.

Hey, My G Pro is on Miui and everything works fine on it. I can enter recovery mode and all that. But, I want to revert back to stock and this low battery error keeps popping upon during offline flashing. I have seen your method for bypassing it, but I have not found a solution. Is there anything else I can possibly do? Thanks!

This is what I did by accident
The problem, as I see it, is once you root your phone and put the custom recovery on it, CWM or TWRP, it overwrites your factory recovery. I tried using a 10k flashable zip I have to get my phone back to stock. BUT once I tried to get the OTA update to 10P, as another member here pointed out, My phone boot looped. So my question is, is there a way to remove the custom recovery and restore the stock recovery WITHOUT having to go through the PITA process of using flash tools? If there is a way it would save people countless hours fixing their phones just to get an update.
I know many of you don't see this as an issue because your whole point IS flashing new Roms. But from everything I have seen of this phone it's more trouble than it's worth. This phone is so very picky it's ridiculous. I just wnna get the damn 4.4 update, have it rooted to remove bloat, and call it a day. But to answer the OP question, you always have the option of buying a battery station online and charging your battery that way.
Fixed low battery error
My friend managed to fix the low battery error. He tested the method on my phone and during flashing the error did not show up. Will be creating a new thread which fixes the low battery warning soon. Stay tuned !

Nice work. And that thread will definitely help allot of others with that issue.
TL;DR
Aside from all the technical stuff, and since the g pro has a removable battery(thank god for that) there are several chargers that you can use which charge the battery outside of your phone. Here where i live (honduras) I have seen quite a few and had one myself(used it to charge spare batteries).

Never thought I'd be the one to create a thread like this..
After I flashed the OKV4 ROM, strange things started to happen (this was after a full wipe). Apps kept force closing, etc. Later that day, when I picked up my phone, I saw the samsung logo flashing over and over. Making me unable to enter recovery.
Download mode still worked though and I proceeded to flash a stock firmware via ODIN. This did not help. Oh, and the Odin flash succeeded, without rebooting my phone though...
So, I'm still stuck with my phone which can't seem to get out of this strange loop.
HELP :C
I remember reading somewhere here that if you have flashed a diff FW now and then a possibility the last recent kernel is still in the system folder etc....this is maybe the cause of the bootloop.
Since you had confirmed going to download mode is possible..this may work logically... Why not do the following :
Get your phone rooted via Recovery (there is a thread here by The-E)..Once done flash arco68's CWM Recovery....Boot to recovery n do this :
Factory Format....Wipe n Clear including Delvik...Then go to Mount n Storage wipe every single folder...System...Data...Etc (this will wipe every single data left behind but I assure you the CWM will not be wiped) once done reboot n put the device into DL mode and use Odin to flash back to the stock FW.
From this moment the recovery will be replaced by stock version and the stock FW will be restored....once it boot up..Walla as I had done this over two times :
Best of Luck !!

I think you misunderstood me :/
This isn't the ordinary bootloop where the boot animation plays. It resets literally 2 seconds after starting. This makes me unable to enter the recovery at all. Thanks for the effort tho.
Tl;dr:I can not enter recovery mode.

So my note 2 had been working very well, but just the other night it turned off and then was stuck at the Samsung logo screen. I attempted to boot into recovery, but it would freeze at the TWRP logo screen. I decided to Odin a new recovery and put the latest version of TWRP on there. I can now boot into recovery, but it asks for a password. I assumed I had just used a bad version, so I tried several others which resulted in the same outcome. Pressing cancel lets me get into TWRP, and it seems as though I can browse files, but trying to perform any other action gives an error message saying that TWRP cannot find the partition for data, system, and a few others.
Is the phone dead? Or is there something I can do to bring it back to life?

Hello all,
LG Optimus G Pro user here (LG-F240S). I recently rooted my phone, then used Gomdol's tool, which roots the phone and installs CWM recovery at the same time. I had initially thought that the application also unlocks the bootloader, but since then found out it doesn't.
Anyways, the first time rebooted into recovery, I flashed a ROM (specifically for F240S), which wasn't successful for some reason. Now, when I boot up the phone, it keeps saying "Secure Booting Error! Cause: boot certification verify"
I have tried everything, from the Volume down + Power + Home to erase everything and do the factory reset, but it doesn't work. I have also downloaded the stock firmware, and tried the KDZ_FW_UPD application to flash the stock firmware, which also did not work (Extract File Error). My last resort was using LGMobile Support Tool, but it keeps telling me to recharge my battery (my batter is currently recharged to 100%, and the USB is plugged in, so something is very wrong here).
I would really appreciate any help, It's been 3 days now without being able to use my phone and it sucks
Thanks!

on your boot certification problem, I had that same problem before and made me panic for two days. I tried LG mobile support tool and worked for the first time. few weeks ago, I also encountered the same error on LG Mobile support tool (battery error,right?) I used I also used the KDZ_FW_UPD application and yes, extract error. but you know what the magical thing is? I found the G2 KDZ flasher from the G2 thread..
even if this was from G2 thread, it worked for my device.
here is the link and of course thanks to @hyelton for bringing this wonderful fix. now, I don't have to worry about bricking my phone again(except for hard bricking, of course).
http://forum.xda-developers.com/showthread.php?t=2432476
one more thing: make sure you download the KDZ. there is a thread here that links to that. but I think you have the right kdz now so just follow the steps. make sure you are in download mode press volume up and down (only the volume up and down. not the home or power) and then plug the cord.
guys, this happens when installing custom rom with lg stock rom in it and your device is not fully unlock. to lessen the hassle of worrying trying to reflash to the stock rom and downloading those huge files..just download any custom pure android rom , slimkat, cm11, etc then flash to your recovery..it would boot again without that error on boot certification. only that your on pure android rom but that's ok

You should be able to get in download mode by following these steps. First take out the battery for atleast 5seconds, put it back in, then press and hold both vol + and vol - and within 2seconds plug in the usb cable, your computer should make the sound of a new device connected, when you hear that let go of the volume keys. The screen should say download mode now.

I have sent it to warranty and they told me that the phone was rooted, they sent me a picture with the back of the phone showing the imei and serial number and a front picture showing me that the phone has the app SuperSu.
They told me that the phone need a new motherboard that cost ~340 $.
Why do they need a new motherboard ? because the phone was not hard bricked.
I will get my device back.
Is possible to get it back with some modifications? I mean if they managed to boot it and see the SuperSu app.
I know to work with LG Flash Tool, so all I need is to put it to download mode.
All the above key combination didn't work. Power and vol- or power and vol+ ......
I will contact you again when i'll have my device.
Thanks!

Long story with guys at warranty. I asked them to prove that the phone in those pictures is mine. From the picture showing my imei, yes is mine. But from the picture showing supersu app....they don't convince me. Every phone could have installed supersu app without being rooted. So i asked them to provide me another picture that will show the google account that was registered on phone and another with all my apps installed. They didn't send me such photos.
If they managed to revive my device and showing me there is a supersu app, that means they don't need to change the motherboard.
Am i right?
So i get my phone back working and they cut my warranty.
I tried vol+ and vol- and usb cable and download mode appeared.
Thankd!

I smell something weird about LG. They probably put SuperSU on there or they got the wrong phone. Anyway i'm sure the community will help Don't lose faith/hope yet
About the warranty, its very complicated.
The store from which the phone was buyed, took it and send it to another warranty dealer authorized by LG, i guess, which was not named LG.
At last, I sold the phone, i own an lg g2 now and recently flash official lollipop.
Gladly and after some fails and always getting the secure boot certification error, i managed to access the download mode and with LG Flash Tool installed the stock .kdz on my LG L90 D405n.. thx for all the hints..
Before of this secure boot my e988 was working but no download mode. I've encountered this on a LG G2, so after some search i've found out that I must downgrade the bootloader. So, I rooted my device and installed autorec.apk from here http://forum.xda-developers.com/showthread.php?t=2715496 that fixes the " no download mode " .
I don't know how to skip the secure boot error. If someone managed please share with us!
Boot : Error Certification Verify
Hi. I am new to this thread although i had used this thread many times with issues i have had. There is this one issue im having that i can't seem to figure out which im usually good at doing by following forums or threads.
A couple weeks ago i had rooted my LG G Pad 7.0 V410 LTE tablet from AT&T. I had TWRP downloaded into it and i had flashed Candy5 it worked perfectly i just didn't like how it looked so i tryed to flash it back to original stock OS. But now when i boot my tablet up it goes to the LG screen and at the top left it says Boot : Error Certification Error. This has me dumbfounded on what i should do. when i connect the tablet to the computer nothing pops up no tablet connects to the computer. I tryed downloading the drivers and everything but nothing seemed to work. I need help with this issue please!!
I didn't know where else to post this issue due to being new!!!
Hi.
I have a problem with my D855. My phone is rooted and runs the fulmics ROM. Everything was working fine, , on Fulmics 5.3, except than one day, I was using my phone normally and then it crashed. I saw the phone rebooting, but for some reason it got stuck. The phone tried to boot unsuccessfully until the "firmware update" went through, after what it reboots again (unsuccessfully) and so on.
At that time, I was able to access twrp, do some backup, and flash properly with a downgraded version of fulmics (from 5.3 to 4.1).
It was able to boot again and use my phone like before. Yet, after one month of usage, the same problem happened on version 4.1. The phone crashed and now cannot boot.
Any idea of where it is coming from? Should I go back to stock? Should I contact customer service?
What did you do before the phone crashes ?
I think you probably should flash the stock ROM and wait for an other crash... or not.

I haven't done anything special. I think that the first time I was playing on candy crush. The second time I was just looking at pictures in my gallery.
I was using the ROM without any tweaks or extra modules such as Xposed. Just regular use.
Update on my situation: I switched back to stock ROM and it seems to work OK for now (it has been 4 days). So I will wait and see if new problems happen. By the way, it was extremely difficult for me to get back to Stock directly from fulmics ROM. I tried several methods that I have found on xda based on LGUP or LG Flash tool without success. For some reason I was not able to connect the phone to my PC in download mode.
The only way that I found was to use a nandroid backup that I did just after rooting the phone and that was based on stock ROM.

You can also use the Stock rom flashable from twrp. So you can wipe the system partition and get a "better situation" than a nandroid backup that should be with an old version.
Or use this that has also root and other improvements.

Same problem here. Normal usage suddenly started to reboot and now it's stuck in boot loop
Coming from Fulmics too - stopped working one fine day.
Now, continues to boot-loop at the initial LG screen. Trying to get into the recovery shows me the the 'Factory Reset' screen, but beyond that leads to boot-loops again. Even the Download mode loops!
I'm at my wits end without a solution in sight.

Thank you for this advice. I was able to update my stock ROM after the Nandroid backup through LGUP, but your method would have been faster.
But anyway, I am waiting to see if I am stuck with bootloops again, using non-root stock version, so I can send it to customer service if this happen again.

Are you using Fulmics ROM as well? Can you have access to TWRP? I was able to connect to a PC in the recovery mode and to transfer files before flashing, in case you need some basic backup...

Silly question, but are you sure that you selected "Yes" when the screen asks you about factory reset? you have to press "volume down" and the "power button", since the default answer is no.

Yes, of course I was able to access TWRP successfully earlier.
Curiously enough, the phone boot-loops in regular startup, Download mode and trying to get to recovery. However, it doesn't restart itself and fall into a loop, while on the Factory Reset menu. Am I correct in assuming that the battery could not be the root cause of the overall problem? Because if it was, it would likely loop even on this Factory Reset menu as well as far as I understand.
Unfortunately, the phone restarts as soon as it lands in the Download mode so I cannot even restore to stock.
EDIT: Okay, weirdly enough it just booted and reached the homescreen before restarting again. What I did was let it charge to a 100% and tried booting while plugged in. Could it be the battery after all? Though this exact set of steps hasn't been helpful before.
I have updated my Nexus 5x to 7.1.1 beta and after a day it powered off and I got the infamous red led during charging. I was not able to turn the phone on even after leaving the charger on for some days. I thought it is bricked and left it alone connected to my computer.
However today, out of nowhere Google logo popped up. It was bootlooping, but I was able to enter bootloader and original recovery. I wanted to flash it from bootloader, but was unable, because it was still oem locked. And I was not able to oem unlock, because I did not do the required part in the Developer Tools menu. I tried to adb sideload OTA in the original recovery, but sideloading stopped after uploading ~48% every time.
So I opted for the "VolumeUp + Power" mode flashing. Phone was recognized and I started flashing the appropriate TOT file. However at 33% on phone and 28% on the PC, progress stopped. And after a minute or so phone turned off. Currently it has no signs of life at all. Have I completely bricked it now? Is there a way to recover from interrupted "VolumeUp + Power" flashing mode?
EDIT: at first I though maybe the battery died during flashing. But interruption was not abrupt. First the progress slowed down to halt. And then after some time phone turned off.
It seems not all is lost. Have a blinking red light again after leaving it connected to computer for a day. Back to square one, but at least it is alive.
Your motherboard is dead.
And it is not your fault, mine also died while using beta 7.1 and I sent it RMA. They replaced for a new one.
But in my case i had unlocked bootloader, I flashed back 7.0 and it gave no results, still bootloop that's why I sent
Thanks for the info.
After leaving my phone with a clamp on a power button throughout the night (so the red light would flash continuously), I got it booting into "VolumeUp + Power" mode and this time I have successfully flashed the same TOT file via LGUp software. It was still bootlooping after flashing. Now I was able to enter into bootloader and recovery and this time sideloading the same previous file actually works. However it still bootloops.
Anyway, I tried to RMA it and after giving my IMEI to the Google rep, they said that they could not find it in their system after checking US and UK store records. Also tried calling LG warranty, but they do not know of my IMEI either. I got this phone from Swappa, so I left wondering where did the original owner of this phone got it from. He claimed that he got it as a present...

out of curiosity, have you ever tried to flash custom recovery through the bootloader ? If you can, you might also wanna try to make a EFS backup, wipe all partition, then flash custom rom or near-stock rom like this one, just for the sake of testing.

I wanted to flash custom recovery but was unable to do so, because device is still OEM locked. And I am unable to unlock it, because I did not do the confirmation in the Developer Options before device started to bootloop. Is there a way to flash custom recovery without this step in Developer Options?

For now, no way that I can think of. You could try to oem unlock it until it work, just cross your finger I guess?
I have some progress here. Since I was able to sideload various OTA images, I started doing that one by one and seeing if some of them would not bootloop. And after flashing 7.0.0 (NRD91N) from here (https://developers.google.com/android/ota) phone booted successfully and now is working. Will report if I get any problems.
