[Q] How to unbrick my 4X - a question of life and death!

I have half-bricked P880. Bought just a week ago.
My ROM is stock V10C. I’m trying to get rid of that crap ROM, but so far without success.
I have rooted the phone but flashify is the only app saing that the phone is not rooted. Every other app which requires root is normally working. I can’t unlock the bootloader because phone can’t be recognized by any computer, using different Windows, USB cables etc. It just shows charging but PC doesn’t see any connected device. Nor the phone shows any connection option when I connect it to PC by USB.
I’ve tried to install TWRP (without success) and CWM (successfully) but the phone can’t be load into bootloader. Just an LG logo will appear and this error message:
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
I think it’s still locked.
This method hasn’t help either…
http://forum.xda-developers.com/showthread.php?t=2251407
What’s more, the error message appears almost every time I try to turn on the phone. Sometimes it takes 10 attempts until the phone will finally boot into Android.
Yes I’ve tried basic things like playing with USB debug mode, LG PC suite option/USB tethering… please don’t respond to my question by that kind of suggestions, I’m no rookie in flashing roms and Android problems.
Only hope for me is to flash kdz file via PC (when the phone is off and battery out). BUT I’m unable to do that, due to problem that the phone is again NOT RECOGNIZED by PC. Of course I've tried every kind of LG driver but the problem is in the phone, because the PC won’t even notify by sound that a phone has been connected to it. So I need to change the corrupted bootloader… somehow.
I’ve already searched everything to this issue on XDA and elsewhere - without any solution. So I’m 95% the phone is half-bricked without any chance to flash new ROM.
If none of those things that you said doesnt work, as last resort you should try this
http://forum.xda-developers.com/optimus-4x-hd/general/s-stuck-rescue-ultimate-rescue-guide-t3012444
Thank you for a quick reply! However the autor of the method says:
i mean when you get stucked with S/W screen, and you can't flash the device in any way
Click to expand...
Click to collapse
In my case I can't say that I'm stuck with S/W screen. Because I don't even get in there. Any PC in my home (XP/Windows 7) don't even recognize that a mobile has been connected to it. So there is no S/W screen. The only way I can get in S/W screen is to keep the battery in, but it doesn't solve anything. Because the phone remains unrecognized to PC. Therefore I'm unable to flash anything. A simple explanation in here arose: the USB port in my phone is faulty. BUT, how that can be, when the USB charging works fine and even S/W screen appears while the battery is in?
Either way I'll keep your suggestion as the final solution(since I'm very skeptical of it and also dont have screwdriver small enought to take out those tine srews) if there will be no other responce to my problem.
I'm not very experienced in things like this, but when I was flashing kdz to my phone, my computer wasn't able to recognize the phone with battery out, so I did whole process with battery in (and it worked)
anyway if you want to unlock the bootloader you have to update to official JB (just flash JB kdz and then wipe data in LG recovery to prevent bootloop)
so first you have to connect somehow your phone in sw mode to computer
then flash JB kdz and wipe data in LG recovery (it should be back even if you've flashed twrp)
and finally root JB and unlock bootloader (for example this way I found by two clicks here at xda, just browse Optimus 4x general category: http://forum.xda-developers.com/showthread.php?t=2251407 )
I hope I helped you a bit
I agree with you SuperLamic. Especially with this:
so first you have to connect somehow your phone in sw mode to computer
Click to expand...
Click to collapse
My only hope is to flash kdz file using fastboot mode. However after days of searching on XDA, installing all kinds of drivers, trying different methods etc., I'm still unable to connect my phone to PC.
Any PC I tryied so far haven't even made a sound while pluging my LG to it. Nor it's vissible in the list of connected USB devices.
So now I'm sure that a USB port on my phone is faulty There is no other possible explanation. But thank you all for your suggestions anyway.
P.S.
There is maybe a tiny chance for workaround by unlocking the bootloader without PC. But this method doesn't work. http://forum.xda-developers.com/showthread.php?t=2251407 With unlocked bootloader I woud be able to solve the problem without PC. Right now I can't install TWRP nor CWM because they require bootloader to be unlocked. CWM in ROM Manager always says that installation was successful but actualy, it wasn't. Since there is always this error when I try to load recowery mod...
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
EDIT:
So I find out that only JB ROMs can be unlocked. It's not possible with my stock ICS. So there is really only one solution: repair my USB port on LG to flash kdz. But I'm afraid that these days a repair will cost more than the phone itself :[

D405n fully bricked - problem

Hello,
few days ago i unlocked bootloader and installed twrp on my l90 d405n. Unfortunetly, something went wrong and now my phone is fully bricked. Windows see the phone only as 60mb disc with two folders, on phone screen is still black.
I tried this: (remove space)
ht tp://android forums.com /threads/guide-unbrick-lg-l70-no-download-mode-no-recovery-mode-no-fastboot.893311/
but main problem is that idk what version of software i've got (10a, 10b, 20b, etc.), only remember it was rooted android 5.0.2. I tried few aboot's, but effect is still the same - nothing happens.
it may be due to bad recovery version o rbad aboot? What can i do?

I have the exact problemm as well.. EXPLAIN!!
I had the same problem, but then i tried the guide with replaceing aboot boot recovery files and now my pc doesnt even see the 60mb disk. When i plug my phone to charger or pc without battery in it shows that its missing but when i put t back in nothing happens the screen just stays balack or shows 0% for a sec. When i connect it to pc nothing happens and when i hold the power button the sound of conecting a device is playd and after a sec the disconection sound plays.
Is there any hope for my device??
come on guys we need a fix please help
If your computer still recognizes it, you may be in a soft-brick. Try flashing your stock ROM onto your LG L70 and wipe caches.

Help, Hardbrick LG L90

Hello guys, i'm new here. First of all english is not my native language so sorry if i make any mystakes.
I flashed my phone to Lollipop. Then i tried to install twrp (with Flashify) recovery so then i could install Xposed... but the thing is that i may have used the wrong file..
My phone doesn't start. The only sign of live that it gives is when i plugged it to the PC, the pc makes the usual sound when you plug a USB. And it shows my phone as a usb with 63MB of storage (obviouly my phone has more storage). And when i go to Disk admin it shows me all the partitios that my phone has.
Also in Devices admin it shows my phone as: LGE AndroidNet USB Serial Port (COM6)
Do you know what can i do to unbrick my phone? :crying::crying:

You probably flashed the wrong bootloader, which is a fatal error.
I know users that managed to recover other phones from this brick with LGBoardDiag as explained in this topic: http://forum.xda-developers.com/lg-g2/general/fix-unbrick-lg-g2-stuck-qualcomm-hs-usb-t2933830
I don't know how to get this TOT file, but the same partitions shown can be retrieved from your KDZ in BIN extension with LGFirmwareExtract, I think it's just a matter of renaming the files.

I meant that will lead you to a working download mode, which is enough to restore everything, including partition table.
I have a suggestion, you said Windows detects as a mass storage unit, can you boot Linux and follow this thread http://forum.xda-developers.com/showthread.php?t=2582142 to see if can see all the partitions?
If yes, it's just a matter of extracting the KDZ of your variant and flashing the said partitions to get a working download mode to make a complete kdz flash.

Secure booting error 1003

So I think I may have bricked my phone unless I can get the H811 20i KDZ file but even that may not be good enough to save it. I'll start with where I am currently at. On boot I get the error:
Secure booting error!
Error code: 1003
Modified
I am able to get into download mode by pressing the up volume key or into the wipe mode by pressing the down volume key. However, no matter what I try I can't seem to get it to reboot normally.
Here is what I did to get myself into this situation:
I stepped through the guide to install MM and then I performed the fastboot OEM unlock and booted into TWRP. I then installed SuperSU and rebooted. Then for reasons unknown I decided I would relock the boot loader and so I ran the command fastboot oem lock. I fully understand the stupidity of that thought now but didn't think very clearly at the time.
Here is what I have tried:
Using the LG Support Tool I attempted an Upgrade Recovery which failed.
Using the guide on here to return to stock I attempted the method using the kdz file for h811 10n but that fails at the upgrading your phone with the error message "Upgrade stopped due to an error". I have attempted the retry button numerous times without any change in responses.
At this point in time I am game to try anything.
:fingers-crossed:
Thanks to autoprime I am now downloading the kdz for MM and when it is complete I will attempt to use LGUP to restore it.
Well I get an error message from LGUP stating that I don't have the correct DLL for H81120i installed. I attempted to replace the dll with the one inside the MM kdz but that didn't work.

Oh I wish it were that simple. I had tried it last night but attempted it again as I couldn't remember what happened. I get an error message stating "Connect your mobile device to the USB port. If it is already connected, contact LG customer service."
At this point I think I may just need the MM dll to use with LGUP. I attempted to use an MSI packaging utility to replace the dll in the 0.0.3.23 installer with the dll I extracted from the kdz file but that got me nowhere.
I attempted to use the LG FlashTool v1.8 and found out that the dll that I extracted is ver 0.0.3.21 which is older than the msi version found on here. Does anyone know how to get a newer one?

I had the same error and sucessfully used lgbridge. You probably need to reinstall your usb drivers.
OK I'll give that a shot.
No go...
I uninstalled anything I could find related to LG. I then reinstalled the LG Bridge software which then updated the USB drivers to 4.0.4. I then rebooted my computer and attempted it again and I got nothing but the same error.

I had this exact same issue when upgrading my phone. Didn't do it correctly and it took me about 3 hours before I got my phone working again. It was about a week ago on another computer, but I'll try to recall what I did when it finally clicked in my mind.
Download H81120i_00_0201.kdz flashable zip from here (1.6GB Feb-04-16):
http://downloads.codefi.re/autoprime/LG/LG_G4/H811/H81120i/
Download LGUP and install it. I used the DropBox link in this thread:
http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
Remember to install the LGUP_8994_DLL file BEFORE LGUP_Install
Download and install LG Bridge (for the USB drivers) here:
http://www.lg.com/uk/support/pc-suite
Select the LG 815 model, the drivers will work. I only used the LG Bridge to install the USB drivers. Nothing else.
OK, now here's where your phone comes in.
Step 1: Turn off your phone (pull the battery if you must, but put it back in).
Step 2: Hold the VOLUME UP button and plug the USB cable into your PC. This puts your phone into DOWNLOAD MODE.
Step 3: On your PC, open up LGUP. The program shoud recognize the phone as H811 in COM3 or COM4. Highlight it and click the SELECT button.
Step 4: Under the "Process" row, select UPGRADE
Step 5: Click the blank space under File Path, it will pop up a [...] [X] at the end. Click the [...].
Step 6: Select the H81120i_00_0201.kdz and click on Start. The program will push the STOCK H811 MM ROM to your phone. This will bring your phone out of Brick mode, but you will have to go through the entire rooting process again.

Woohoo!!!!!!!!!!!!!! I changed two things and I'm not certain which one it was that finally made it work but I followed your steps and installed the LGUP_DLL before the application (upon re-reading the original thread for the LGUP program I see that is the way you were supposed to do it the whole time, so much for reading comprehension) and the other was I ran it from a Win 7 VM instead of Win 10.
Big thanks to you and also to bender_007 for walking me through a bunch of stuff and recommending the VM approach.
I did the exact same thing, but I cannot get LGUP to recognize my device. Uninstalled and reinstalled drivers and all. Any other ideas?
I did the following:
Installed Windows 7 in a VM
Installed the LG Bridge software and ran in do it should update
Installed the LGUP DLL
Installed the LGUP software
Connected phone to VM
Then ran LGUP tool

first of all, how can we make PC detect our G4?
actually, even w/o any drive installed in PC, the PC should detect G4 if it works normally.
Device Manager shows my device, but as "LGE AndroidNet USB Serial Port". From what I have read this may be it's bricked mode. Is there anyone with an idea on how to come back from this?

MM relocked the boorloader was stupid.
I had this exact error yesterday. I used cdmatool to get some bands enabled so I could get AT&T LTE with an AT&T sim and T-Mobile phone. All went well, and on my way out I figured since I had done the fastboot oem unlock, I should probably relock it. BAD IDEA.
By the time I found this article I had figured that somehow I needed to reflash to a ROM with a unmodified bootloader. This article is great! Such a rare treasure - all of the links to the necessary software and a short-but-sweet guide all in one. This post saved me hours, maybe days, of searching and trial-and-error.
By the way, since I had already installed the LG device drivers (available here) it was not necessary to download and install the whole LG Bridge.
THANKS!
Many times tried to flash my H811 to 20i but always ended with blank screen...is it have to wait until 5 to 10 minutes to get the phone rebooted after flashing with LGUP? Because usually ended with blank screen and qd mode, have to revive using qfil, imei unknown, camera and google play store always closes.

Did you unlock your bootloader first using OEM unlock and fastboot before flashing the bootloader?
Try this,
Download the MM kdz file for your phone here,
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
Then follow the instructions EXACTLY on the following link and attempt flashing the kdz, install the DLL first then LGUP and follow the instructions to do a full wipe and install MM,
http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
After that, follow the instructions on the following link to unlock your bootloader.
http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
That doesn't work if it does I'd be delighted to know how
Secure boot error 1003 means you only have download mode to boot into
Likely lg up tool will either not see your device or it will say model unknown.
I've been sitting secure boot error bricked for a week with no explanation on fixing the Unknown device model issue with that tool.

Try uninstalling LG up, the DLL, and LG bridge from your computer. Reboot, and start over. You are entering download mode with LG UP correctly right? First, install DLL then LG UP. Turn off phone and with LG UP running, plug in usb cable to computer and into phone, remove battery from phone and put battery back in and the phone should enter download mode automatically. Follow the rest of the instructions in the LG UP thread to flash the kdz. You can flash the stock kdz with a locked bootloader. Your PC is the problem. If you manage to flash the kdz, be patient. It reboots several times. Don't unplug it during this process.

But I'm scared to think that relocking the boot loader screws up what PC driver settings were reading from the phone such as mtp mode.
So the question is how do you get a PC to recognize download mode with drivers does download mode Still REACH a signal across to the PC.
Are these a special set of lg drivers or Lg bridge drivers which are called Lg air driver update that bridge tool forces you to update too .
What makes you think also that This Unknown model is going to go away its already been stated that it remains because If you was on a ROM and not stock this occurs and no way around it .
I'm not saying lg up doesn't see my device it just sees it and detects model unknown so what I'm saying is the pc and Lg up tool is actually seeing the Lg g4 but just reading it as a Unknown model which then prompts you to choose correct model which you can't

That doesn't work if it does I'd be delighted to know how
Secure boot error 1003 means you only have download mode to boot into
Likely lg up tool will either not see your device or it will say model unknown.
I've been sitting secure boot error bricked for a week with no explanation on fixing the Unknown device model issue with that tool.

I couldn't restore my phone with the KDZ so I went to T T-Mobile to replace the phone

I'm just throwing it away it's a headache at this point
I can't take it to T-Mobile cause its not on an account I got it on trade from a friend
And it is paid off but it would be a hassle with no account tied to it also Lg would hassle me for a warranty replacement likely wanting proof or seeing its bricked first then telling me I did it
