Lg Optimus G pro E988 Doesn't BOOT (maybe bricked)

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 ?

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.

[Q] Bricked Nubia N7 Mini?

Hello everyone, i'm new to this forum and i hope anyone can help me. I recently received a Nubia z7 mini. It's an awesome phone! However just tonight i tried to upgrade using the OTA option. When my phone rebooted into the Nubia v1.0 recovery it kept displaying this message:
E: footer error
E: signature verification failure
operation aborted
The phone then rebooted.
I then searched for other ways of updating and this is where i went wrong. I downloaded the latest official update, placed it on my phones external SD and tried to install using flashify. Since the search for zip file option didn't load properly i clicked on 'boot image' (really didn't know what i was doing there). It then loaded the zip file, and asked for my okay. I then rebooted and the phone didn't start anymore, it's just stuck at the Nubia logo. I can get it into recovery mode (Nubia recovery 1.0) but if i try to flash a new rom i keep getting the above errors (footer error and signature verification error).
My phone is not being recognized by windows right now so i cant flash with odin.
Is there a way to fix this phone ?
Many thanks in advance!

Well, I can inform that you do need a custom recovery on that phone in order to flash a custom ROM... Or it wont work. But i dont have that phone, you can try this.
1.copy ****.zip to root folder of the phone SD card (no need to unzip).
2.Turn off the phone, then keep pressing power button and volume+ button until the robot icon appear, then press power button again and it will show as below
3.Press the volume- to move up and down to choose“wipe data/factory reset”, then press volume+ button to confirm.
4.Choose “yes—delete all user data”, then press volume+ button to enter the page as below.
5.It will enter below page after finishing delete all user data.
6.Then choose“apply update from sdcard”
7.Find and select the ROM, press volume+ to enter the page as below.
8.Please make sure the power is sufficient during the upgrading. It will showed as below when the upgrading finished.
9.Choose “reboot system now”,then press volume+ button to reboot your phone.
Also, Are you rooted?
Regards,
Exxo

Hi Exxo,
Thanks for your reply. Yes, i am rooted
Now in step 1 what do you mean with ***.zip. Is that supposed to a zipfile to change the recovery?
i tried downloading and flashing Clockworkmod Touch Recovery 6.0.4.3 CWM (downloaded from here: http://forum.xda-developers.com/showthread.php?t=2531628).
However it is giving me the following error:
Finding update pakacge
Opening update package

E: failed to verify whole-file signature
E: signature verification failed
Installation aborted

anyone?

[Q] HELP! GPE lollipop OTA Update Error, no apps loading after that

Hello All,
I have GPE version of GPad running Kitkat 4.4 Stock ROM. Last month I have used following link to enable chromecast mirroring. Due to the issues i have uninstalled superuser app and did factory reset. After that all well! I mean no issues with tablet.
http://forum.xda-developers.com/har...experimental-enable-mirroring-device-t2812193
Yesterday I tried to sideload the GPE lollipop update but prompted with following error.
"/system/etc/audio_policy.conf" has unexpected contents.
E:Error in /tmp/update.zip
(Status 7)
Installation aborted.
This morning I saw system update notification for Lollipop upgrade and opted to install it, but without any further msg during the system update it prompted with "Error!" After that I did factory reset. When it reboots starts optimizing 48 apps, but it prompts with following sequence of messages:
"Unfortunately sun beam has stopped. "
None of the apps loaded , no access to setting, just empty screen and on screen buttons at the bottom.
I spent quite some time looking around in xda to restore back to factory, none seems to work.
1. Tried flashing original stock .tot file, getting "Download user image is only available in the online environment!!
2. adb sideload, "/system/etc/audio_policy.conf" has unexpected contents
3. To Flash TWRP i am not getting access to setting to enable USB debugging.
Now i cant even put the G Pad in adb as i dont have access to settings to put in USB debug mode. vol down+power puts into bootloader, but cant access to adb commands.
Now I can only access to recovery and do sideload. but i am stuck with "/system/etc/audio_policy.conf" has unexpected contents error. Can someone share kitkat original version of audio_policy.conf? also how i can replace the exiting file as i dont have access to adb?
Greatly appreciate your help to bring back the G Pad.
regards
Raj

You can boot twrp from fastboot and flash either 4.4.4 or 5.0 back onto your tablet. Look at the thread in Android development for more details on flashing the stock images using twrp

Thanks! I was able to get back to kitkat with following method. I was able to flash recovery its now back to complete stock kitkat now.
http://forum.xda-developers.com/lg-...510-gpe-4-4-4-ktu84p-l002-stock-twrp-t2797883
After this I got system update notification to lollipop. Again got "Error!" msg during the install process.
I tried adb side load, got following error!
failed to verify whole-file signature
signature verification failed
installation aborted.
Any thought whats going wrong there?

LG G4 H811 (T-Mobile) - Unable to get into recovery / fastboot or Install TWRP

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?

[Problem] Bootloop "Your Device is corrupt." Can't access recovery.

Hello,
Woke up to my phone turned off and upon turning it on showing the Your Device is corrupt error and after 30 seconds a reboot happens automatically. I remember I had a "low disk space" alert for a few days. I think there is absolutely no free disc space. I can't access recovery as when I hold down any buttons it turns on and quickly shuts down within 1 second upon the first screen showing.
Don't know what to do. I had many important files on it as well.
Any tips would be massively appreciated.

Why are we facing this issue?

+1
Any solution for this?
My device is also facing the same issue.

Factory reset is the only option!!
connect your phone to pc in normal charging mode and then try booting to recovery mode (power&vol+), you should be able to boot to recovery.
you will loose all your data.

Sadly this is clearly not working. There is quite a few posts on the nokia forum relating to this and the android 10 update bricking the device. But so far there is no solution and as well as that, the recovery mode is not available.
There appears to be some opportunists on youtube that are exploiting this to profit to fix the device, but that is no real help.
So I'm also in the club of a bricked Nokia (well its my mothers phone) that has remained stock the entire time. (it's a good thing I kept my Nexus 4!)

Try booting in fastboot .
Poweroff your phone .
Connect to pc .
Press (vol- & power) until the logo appears with a little fastboot written in left bottom.
If you are able to boot into fastboot then tell me I will give you the solution.

Yeah, it's refusing to go into fastboot, just keeps going in a cycle back to the corrupt error again

Yeah, thats when it goes into cycle even more so, android one screen comes up, quick flash of the corrupt error, then it starts again.

Sadly it is lifeless now, believe the battery has ran out and the phone refuses to charge in this state

solution
Hello i had the same problem , i recovered my 5.1 plus this worked for me maybe it works for you too.
First download sp flash tool and firmware file i have 5.1 plus world wide version and dowload the image PDA-209B-0-00WW-B06 for x5 use the image with cn not ww.
Unzip flash tool and the image PDA-209B-0-00WW-B06.
Run sp flash tool load the scatter file from the image, then unthick the box sutinfo, systeminfo_a & cda_a and hit dowload, conect youre phone holding volume up and down until it starts download.
Wait until it finish and the green box wit ok appears. Now the phone will start and after android one logo,the robot image and no comand will show up, click power button then quick on volume up and recovery menu shows.
Now you need a micro sd card and OTA update file download the Android 10 Update (V3.11A) : ace851ea59294177f677018648d6c0614317510e.zip.
Copy the zip file on the micro sd then insert it on the phone. From the recovery menu choose update from sd card then select : ace851ea59294177f677018648d6c0614317510e.zip
The update will start wait untill recovery says succesful it will take some time be patient. After that reboot all done youre device should work. Its my first post i cant post links sorry the sistem wont let me.

You left the most important step .
Readback step in SP FlashTool.

Hey folks!
Let me share what worked for me when I solved this issue on a friend's phone.
This guide is dependent on you being able to boot into recovery mode - the screen with the green android robot laying down with a red exclamation mark on top of it.
We'll use recovery mode to sideload an OTA image to the device. Go to the Nokia OTA repository on telegram (search for Nokia OTA repository). Once there search for Nokia 5.1 plus and from the search results look for a full Android 10 OTA image with the April security patch (sorry, can't post links - should be 1.23 GB). Download that file and move it to the root directory on your SD card and then insert your SD card into your device.
Now, boot into recovery mode on your device (there's a key combination that will get you there but I'm not exactly sure what it is - try Power + Volume Up or Power + Volume Down). Once you get to the recovery mode screen, press Power and Volume Up to load the recovery menu. You'll see a bunch of options listed there - the one we're keen on is 'Install zip from SD Card'. Scroll down using the Volume Down button until you get to that option and then press the Power button to select it. You should then be able to select the zip file you downloaded earlier from your SD card. The process should then take a few minutes to complete. If all goes well, you can now reboot your device and Profit!
Good luck!

Readback is the most important step when you are flashing stock rom .. it backups all the partitions in a single file which you can use to restore if something goes wrong .. many users have faced issues because they didn't do the readback process . You can check out the guide for downgrade and there is nothing to search about .. if you can access recovery/fastboot then it's very easy to restore . If you can't you will have to flash the stock rom . You can check the guide in Guides thread. You just got lucky .if something went wrong you would have end up bricked up your device bad.
