Hey.
First of don't cry.
Now, you have TWRP right?
Grab an external SD card and load a ROM onto it through the PC (for GPad)
Put SD in GPad, factory reset device.
Now go to install, external sd, locate ROM, Swipe to flash.
After flash wipe dalvik and cache then Boot to ROM.
If above fails.
Download LG PC suite and install LG drivers to PC.
Plug LG GPad in PC
Run the LG Suite click Upgrade recovery.
Now it will download stock LG ROM and after download will flash automatically.
Will then reboot after flash.
Hopefully now is fixed.
If hangs at boot screen boot to stock recovery, (power off, power button + Volume down, when LG logo appears let go off all buttons, now press all three in. Will need two hands for it,)
Then get a factory reset prompt, click power button twice to perform a factory reset.
Hi there, I recently bought an used unlocked LG G PRO E988 (made in korea) version. I rooted it. I tried to flash a custom rom but got stuck in boot loop with a security warning saying "SECURE booting ERROR!! Cause: boot certification verify" But while booting if I kept the volume up and power botton pressed it would give me "SECURE booting ERROR!! Device is unlocked so booting success" , However i could not get into the download mode no matter which ever key combination i tried. Finally pressing the volume up ,home key and power botton at the same time while putting back the battery on i ran into recovery mode and flashed a new rom "sphinx" and it was working fine, though I kept getting the "SECURE booting ERROR!! Device is unlocked so booting success" while booting up. I installed the Philz touch recovery while installing sphinx rom but day before yesterday I wanted to install the default cwm recovery and flash sphinx again with less apps,so from the recovery mode i wiped dev cache,wiped cache partion (and i think i wiped data/factory reset as well ) installed the sphinx rom again and rebooted from sphinx installation screen where i need to check a sqaure box to reboot. but my phone got stuck in boot loop again and with the same security warning "SECURE booting ERROR!! Cause: boot certification verify" but this time pressing the volume up and power button while connecting usb or putting back the battery didn't change the security warning to "SECURE booting ERROR!! Device is unlocked so booting success" neither could i get into my recovery mode. And i have always failed to log into download mode. I read almost all the threads about how to get into g pro download mode but never succeed. The only screen i was getting besides "hard reset" and "boot logo with security warning" was a screen with this message "Recovery mode,Using this mode, service center can back up and recover your data. Press and hold the POWER key more than 8 seconds to reboot and continue using phone." which would eventually take me to the boot loop again if i kept pressing the power button. sigh ! And at this point my phone was not being detected by my pc. I tried "[GUIDE] Optimus G Pro Full Hard Brick fix" by ricanares, but i couldnt get to download mode so the process failed for me After searching for hours and reading tutorials i found out about pdanet drivers and mtk droid tools. which finally detected my phone in pc only when the creen " Recovery mode,Using this mode, service center can back up and recover your data. Press and hold the POWER key more than 8 seconds to reboot and continue using phone." appears. Using mtk droid tools i tried to use a boot image (from an extracted .tot file)and recovery(from same .tot file) but i was getting an error saying no split boot image found.Tried using extracting a .tot file and sideloading the recovery.bin and boot.bin .Tried pushin and sideloading cusom recovery.apk files and all efforts in vein. For any files i send using sideload my phone shows an error "E:footer is wrong ; E: signature verification failed" Using mtk droid tools i could enter into a recovery mode but i dont think it is the cwm recovery mode. it has fewer options. I am so lost at this point ! I need some expert help ...
Things working
1. Boots into stock recovery using mtk tools.
2. Pc recognizes device as LG Android net phone
3.Mtk tools recognizes the device as LG E988
4.Can use adb sideload options to send files to phone in recovery mode (but phone outputs error as 1st attached image )
5.In recovery mode I can see and go into /cache folder using update from cache option.but theres nothing there
THINGS NOT WORKING
1.Doesnt Boot into recovery mode using physical buttons
2.Doesnt Boot into download mode
3.Cant get into fastboot mode with adb commands
4.Doesnt mount sd card .(tried formatting sd card with sdformatter)
5.Don't have a proper backup of my phone.
6.Can't extract downloaded .kdz files to get the boot.img and recovery.img files (tried using lg p970 rom converter, optimus L9 image extractor and lg extract)
HELP
1) Does anyone have extracted .kdz for e988 that has split boot image ?
2)How can i fix E:failed to mount /sdcard error.
3)How do i get to download mode in e988 ? is it possible that i deleted the mode ?

"However i could not get into the download mode no matter which ever key combination i tried."
Have you tried:
1) remove battery
2) hold down both volume buttons and power button
3) insert power cord while keeping buttons held down
4) download mode is yours to cherish??
And for once you get into download mode: your KDZ! (or more here)
From there to go here and do more things. Things cannot be left undone. They hate that.
" SECURE booting ERROR!! Device is unlocked so booting success"
This is normal once you install a custom recovery. As long as your phone works, ignore.

Thanks for your response. Yes i tried that but didn't work. I tried with and without battery both. actually tried numerous times.Only the soft keys keep flashing and nothing else happen. But i will give it a shot again. Plus the secure booting error has changed to "SECURE booting ERROR!! Cause: boot certification verify"-- is it just because I am back to stock recovery ? If only i could get into download mode life would have been a lot easier !! (finger crossed)

Still boned? The LG Support Tool worked for me once, when I was in a similar situation way back last month when I first began smartphoning.
I was in this *exact* same situation after trying to flash my first ROMs and recovery stuff, but I don't remember how I got out of it. :| ACk!
Yupp still stuck . Will try again later tonigh. Didn't get a chance to sit with it the whole day. Hoping for the best !!

Oh! One thing to remember: always plug your USB cable directly into your computers motherboard USB ports, and avoid plugging into USB hub ports (like via a monitor or keyboard). If a desktop: that also means don't use the ports on your computer system. always use the rear ports that plug directly into your motherboard.
(A couple of times I was able to flash a stock TOT/KDZ via the USB hub on my monitor, but that is not a feat that is repeatable for me.)
This makes *all* the difference for me.

The Why: You can't flash that via the stock recovery. You need to use FreeGee to flash CWM or TWRP.
You can get your system into stock recovery: this is good! Does ADB recognize? If not check Windows drivers. If ADB recognizes it, and you can 'adb shell' into it, maybe I could walk you into rooting and installing a custom recovery via the shell?
1) If not already, have ADB at hand. It is your best friend.

Dude, you are so in the wrong program:
LG Flash Tool 1.8 -- this is what handles your TOTs.
Err, wait, you're on E988? Nevermind, no TOTs for you. I've only flashed KDZ a few times, and I don't recall off hand. :| I think it was this one that worked for me: here.

Yes I can actually get into shell using adb. and my device is recognized as an adb device in device manager. If u can walk me into rooting through adb that would be awesome. specially if i could install a cusom recovery. I spent a bit of time yesterday looking into the files in my phone through adb. tried to change the default.prop file , and push in a custom recovery, but no luck. and i could be wrong but I think for some reason my internal storage (/sdcard) is not being mounted.and same for my external sd card.
But i highly appreciate your response dear Thanks alot for looking into it.

No doubt, what kind of jerkoff would do that!
I was on stock Kitkat 4.4.2 and I installed a custom recovery on it, TWRP to be exact. After backing up the stock ROM, I tried to install the Custom ROM but all of my files were gone because I wiped everything off my internal SD card. Now, whenever I tried to reboot it got stuck on the LG screen. I then tried to install a KDZ file via LG Flash Tool but unsuccessfully. Now whenever I try to turn on or go into download mode, it shows an error in the top left corner and it says "Error: secure booting error" and then just turns off. I can't go into download mode, nor can I go into the recovery. Can someone please help? I have been looking all over the internet for a solution but without any succcess.
Also, my phone turns off imidiately when I try to go into the download more or try to boot it up the normal way.
Hello, guys!
I stupidly bricked my D855 trying to install CM 13.
It was on Stock Lollipop.
Now it only flashes red and blue led. No system and no recovery.
This is exactly what I did:
1. root
2. install TWRP 3.0.0.0
3. reboot to Recovery mode
4. completely format all partitions
5. upload CM13.zip and Gapps.zip
6. try to flash CM13
Here I got an error about the Baseband version and the flash did not started.
It was version 20B I guess.
7. Search Google about the error and found an update to version 30B
8. Download the firmware.zip and upload to phone
9. Flash firmware.zip
10. reboot
This is where I got stuck.
I thought it would boot to recovery again, but it is completely dead.
When I power the phone on, I can see the LG logo with this error at the top left:
ERROR : boot certification verify
[660] ------------------
[660] Secure booting Error!
[660] Cause : Boot certification verify
[660] -----------------
And then the screen turns off and the led flashes red and blue.
If I try to push Power and Volume Down, I got the same thing.
If I try to push Power and Volume Up, the screen turns off, but the led don't flash.
If I push only Volume Down the phone reboots to the LG logo.
LG Flash Tool does not detect the phone.
I've searched on Google, YouTube and here on XDA and did not found anything.
It was stupid to format all partitions, I know.
Is there a way to recover the phone or I should buy another one?
Thank you very much for the help.
Hi, guys,
Download Mode still works.
Using LG Tool, the KDZ method did not work, but looks like the TOT+DLL mode works.
Unfortunately, I could not find the files for my specific model D855P.
The tool recognizes the phone at COM41, but the files for D855 are not suitable.
Anybody know where I can find the TOT and DLL?
Thank you!!!

It's a google search for your required firmware. Try it.
https://www.google.com.pk/search?q=...rome..69i57&sourceid=chrome&es_sm=93&ie=UTF-8
Thank you very much for the help.
Unfortunately I did not found the correct TOT and DLL for D855P, but the KDZ file worked.
I changed the Mode option on LG Flash Tool from DIAG to Emergency and the flash did the trick.
Now I'll try to upgrade to stock 6.0, root, install TWRP and than CM13.
Thanks, guys.

Thanks, man!
The flash of the KDZ file fixed this error, but it's always good to have this fix.
At this very moment I am ready to root my new Android 6.0 Stock
Hey Guys! Here is my problem.. So I am trying to update to Marshmallow and I'm currently running Lollipop and OTA doesn't work for some reason (My Phone is rooted).
1. LG Bridge Doesn't work. It detects my phone but it wont update it.
2. I tried flashing a KDZ File using LGUP (Software version: 20i). That doesn't work either. Once my phone enters download more I get an error "0x2000 CEFS::Can't Initialize"
3. I tried installing TWRP but I can't get into recovery mode / bootloader. When I enter "adb reboot bootloader" it will simply restart as usual into the OS, except that in the top left I see a message that reads "Secure Boot Error :1003"
(The reason I am installing TWRP is because I have a flashable zip file for 20i)
4. Since my phone is rooted, I was able to install flashify from the play store and when I try to flash twrp, it gives me a success message but upon reboot it simply reboots into the OS again, and has that message in the top left that reads "Secure Boot Error :1003".
5. The button combinations to get into recovery mode don't work either.
6. I am thinking trying to use a TOT and DLL file but I can't seem to find them anywhere (Can I get them from the kdz?)
Even if could get into fastboot that would be appreciated. I do not understand why I am unable to get into fastboot!
My Phone is the T-Mobile Version (H811) Currently Running Software H81120H (Lollipop)
Which key combination do you have tried exactly to get into recovery?
