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...

Keep trying it over and over. If it still doesn't work I have no idea what you could do. Can you explain how you got in to this problem?

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).
Hello, I've spent about the past 5 days trying to figure this out. So, how this started was, a while back when I first got the phone, I wanted 4.4, so I rooted my phone, and tried to flashify a recovery like CWM and TWRP. Both of these failed. I tried many times, and no matter what I tried, flashing always failed. But guess what, my stock recovery was erased in the process. I forgot about it until today, where I found the OTA update to 4.4 was released, and attempted to do it. To my dismay, I forgot I had no recovery mode, and instantly got the "boot certification verify" error screen. Now All I can access is download mode, to my knowledge. So I've been trying to fix this, either by installing stock recovery, or another way to install a custom. All to no avail. When I use the lg flash tool for the stock recovery, it fails at "BIN CRC Check". Every.... Single.... Time. Despite downloading multiple replacement files. I would be perfectly content with installing a customer recovery, but the ways I see require the phone to be on, and use the built in recovery mode. At this point, my phone is bricked, and I am looking for any and all ways to either A) boot back up normally without installing a recovery and fix it later, or B) install a recovery, even if it's the hard way.
Update:
I followed this thread:
http://forum.xda-developers.com/showthread.php?t=2582142
It looked like it was going to work. I am using a Xubuntu virtual machine. I was copying the files over, and every time it finished copying a file, it unmounted and remounted my phone (I don't know if that was suppose to happen, just worth mentioning if it wasn't suppose to). I was super excited to do it. Hard rebooted my phone. And now it's just a blank screen. I have no logo, no error, and no download mode like I had before. Seriously need some help here.
Update#2:
I have the flash tool correctly working. Awesome! But..... I still have no download mode here.... So I can't use the tool....
Lastly, I am aware of the title.... i don't know how that happened. I intended to type "need", but somehow that happened. I do not know how to edit it.
Can you enter recovery?

Ouch bud you are hard bricked pretty much. It sounds to me from what you explained all the partitions are wiped clean. I don't think there is any recovery from that unless you have a nand programmer

Im confused you said you had download mode then didnt? If it works try using the alternate G2 dll named 8974, because the second time I used Flashtool only the alternate dll worked which is weird because just hours earlier I had used the original, the original said wrong model/download failed the second time.

Try this

Then use LG Flash Tool, the Verizon guide works for LS980. Except use LS980 dll, and you must use Verizon USB drivers (Not T-Mobile, ATT etc), or Flash Tool wont work.

from what he said it sounds like a hard brick
Damn, not even fastboot? Feel sorry for you.
First, recovery works. So the phone(D855) itself is ok. The problem is after i power it on. The LG logo shows, but the bootanimation doesn't and it just turns off after that. I have tried flashing different roms and kernels but all have the same result. Charging to 100 doesn't work. Removing battery doesn't work. All I did was took my SIM card out and replaced it with another one then this problem happened. I changed it again and removed it but the same thing happens.
In short, I turn the phone on. LG logo shows, bootanimation doesn't, then the screen shuts off. TWRP works fine but it seems like the phone won't load or something. Any help would be appreciated!
Try putting your phone in Download mode and then flash a firmware (.tot), Follow this guide here:
http://forum.xda-developers.com/showthread.php?t=2785089
Update: I flashed a custom stock rom (Limited rom)and it actually booted. So I think CM/AOSP roms may be the problem or it could be xposed/kernel/other mods since i only managed to boot with the rom itself. But I'm still not sure about it.

I'll try that again when there's nothing left to do. Thanks for your suggestion.
Hi,
My H815 always suffered from this problem: http://forum.xda-developers.com/g4/help/fastboot-download-mode-problem-t3466649 - the only way I could have fastboot was from an adb shell.
Well, that was not a problem until today: CM14's nightly broke (booting just loops at the moving logo) and now I have no way to go back to fastboot. And if I try the recovery mode, I just have a blurry circle saying "erasing" for a few seconds, then a looping CM logo.
Anyone has a way out of this mess ?

When you say you try the recovery mode how do you try to get into it? Btw do you have twrp installed?
Same thing happened to me, tried to install, just got put straight back in to TWRP after boot. Tried installing a stock ROM, CM ROM & using LG Bridge to recover, to no avail. Help appreciated, (i'm assuming LGUP is going to come up a lot)

Sorry, it's nearly the same issue though, CM14.1 broke phones today.
Today's update broke mine as well. Looking for solutions. Will follow your thread and progress.
Same for me. Tried download mode with lgup to flash stock which worked once - but I kind of bricked it again by trying to install cm14.1 again. Then i tried to go back to stock using lgup again, but now lgup it just crashes. The phone now goes automatically to download mode after turning it on, the progress bar stays at 0%, the phone says "633A B100" and lgup crashes after 9% "prepare dlmode" or something similar. any ideas? :/
Some people seem to have fixed this issue by flashing the official Cyanogenmod Recovery.

After flashig the CM Recovery via TWRP, i can't use the recovery anymore. If i boot into CM-Recovery the display shows "Ereasing" and start the system. After that i got a bootloop.
Is it possible to use fastboot??
You guys should also check CM14.1 thread because people there are talking about the same problem. The latest post says the only solution was to flash an official kdz with LGUP.

And the two times you tried to flash CM, that was with the same recovery ?
Can you go into fastboot mode ?

Yes, it was with cm recovery 20161130, if i remember correctly.
Sadly now, i can not go into fastboot. The phone goes directly into download mode. My windows vm detects the phone, and tries to flash a recent kdz, but lgup crashes at 9%. The phone still shows "0%".
Oh that's bad. What about another kdz ?

Already tried like 3-4.... Its always the same. If the tool would at least give me a little bit more information, but it just stops.
I don't know then. Some users seem to have had the same problem (stuck at 9%) : http://forum.xda-developers.com/search/forum/4233?query=lgup 9%
I had the same issue, tried several things, my final solution was:
- Start in download mode (Volumen up and then plug in cable)
- use "LG Brigde" on Mac to install stock Rom ( Software update tab in APP ) guess should also work with Windows
- Boot original android
- enable usb debug
- Start bootloader via ADB
- fastboot flash recovery to twrp 3.0.2
- Boot in recovery via power and vol down (first factory reset from stock appears but after this twrp is starting)
- install cm nighty of 1 DEC via ADB sideload
- reboot and done
In the meantime i updated to twrp 3.0.2-1., installed gapps etc. everything is now working fine again.
Hope this is also working for you.
Which version of cm14 did u download and install? Can u please post the exact version?
Mmh ... LGUP is the Windows utility right ? How do I do if I only have a Linux machine ?

I'm trying to get to it via power+down, I get to the double "do you want to factory reset ?" question, but then :
- sometimes the CM recovery just says "erasing" for a few seconds and reboots to (non-working) CM
- sometimes it just plainly boots to (non-working) CM
I used to have TWRP installed but it didn't work with CM update, so I let CM install its own recovery.
Hey guys, I've given up. For every step I make it gets worse.
I had rooted my OP with Magisk, and one night i decided to update my OP. I woke up and tried to turn on my OP, it went to 1+ screen as usual but then the LED went white and the screen totally blank.. I couldn't do a thing.. I decided to wipe everything on my OP with TWRP recovery mode, but it made it worse. Now when i turn it on it starts a bootloop. Recovery mode is totally gone from the phone, and my computer and ADB can't detect my OP. The only things I can do now is going into bootloader or turning it into an endless bootloop.
Can you guide me through this?

ADB doesn't work while in the bootloader...
Might still be possible to use fastboot in bootloader mode to flash TWRP, boot to recovery, connect to a computer, transfer over a full OTA zip and flash that.
If nothing else though, the unbrick tool likely works...

Probably exactly what the unbrick tool would do, except it would more than likely use stock recovery instead of TWRP.

So, in other words it'd be less work using fastboot, because you'd have TWRP from the start and could put whatever ROM version you'd want on there straight away... :laugh:
