[Q] Hard Brick D800 - Please Help! At a loss

Any help is appreciated! First some background:
Flashed device to stock using KK 4.4 version d80020c following steps found here http://forum.xda-developers.com/showthread.php?t=2432476. Successfully rooted using directions (and ioroot25) found here https://www.youtube.com/watch?v=HKuedInhdjU&noredirect=1.
Here's where I got into trouble...Downloaded TWRP 2.7 recovery img and flashed via Flashify. Since this step, my D800 has the exact same symptoms found on this thread http://forum.xda-developers.com/showthread.php?t=2582142.
- No download mode (tried many times)
- No recovery (tried many times also)
- Secure booting error
- LG detected as qhsusb_bulk in device manager
- Device is recognized as 15 different drives, one of which contains a folder named image with 79 different files being .B0X files and Microsoft Access Add-in Data files
- Upon restarting, LG logo with secure booting error, then the screen goes black while your phone is still on
I've followed the steps in the thread that matches my G2's symptoms, run ubuntu 13.1 in VM, apply usb filters for my device which is then recognized as either LG Electonics Inc. QHUSB_BULK or Unknown Device 05C6:9006 when running in VM.
Upon running command ls /dev/sd* in VM Ubuntu Terminal, all that is returned is /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 which are the partitions for Ubuntu, no LG.
I've tried to download and update the Qualcomm drivers, device manager tells me that the drivers were recognized, but cannot be installed and do not pass the hash check (Note: PC is running Windows 8.1).
I've spent over 12 hours on this trying to fix this problem, researched and searched everywhere. If I could get ubuntu to recognize the device, I would be able to continue on with the instructions on this thread http://forum.xda-developers.com/showthread.php?t=2582142.
Links for windows 8 qualcomm drivers, suggestions on how to get the device recognized in ubuntu vm, experiences from others in similar situation, or any with experience working with LG to get a repair done if I'm SOL (as in eMMC is fried) would be so helpful right now.
Thank you all!

After flashing recovery did you flash a patched kernel to boot stock kk?

I had the same, also with a lot of drives etc.
Screen is black but low backlighted?
Then try with pluged USB Cabel in Phone, hold Power button until screen is realy off, then hold the Power Up Button and plug Cabel into PC.
So I got download mode after I tryed many times

I had problems a few weeks ago getting mine to go into Download mode... turned out that the cable I was using was great for charging, but sucked for everything else. Once I switched to a different cable things worked fine and I was able to load D80010c on the device.
I was running D80020c this morning (with the D80010c boot.img to have a custom recovery) and decided to do an update. Since you can't load D80020k if you have the older bootloader I went all the way back to D80010c, updated to D80010o, D80010q, D80020c and finally D80020k. I was able to root that using IOroot and have restored everything back onto my phone.

Thanks so much for the responses! I've tried endlessly to get the device into download mode, and tried a new cable to no avail. Any other suggestions?

The URL you've linked to will help you solve your problem.
So once you power off your device, hold volume down and power till the lg logo shows, then release shortly and hold them again together till the white window with "factory reset appears", you should notice a text behind the white screen it's fine. So right now when you think it's gonna enter recovery mode the screen is gray(not black), now you connect your device to your ubuntu or whichever linux. You will notice the screen repeatelly blinking when linux is trying to automount the partitions. Figure out which device it is according to the messages it throws. (sdc, sdb, sdX)
This way you should proceed according to the instructions on the thread you linked.
d800 partitions are here

Still no luck

Thanks for your advice.
I got the white screen asking whether or not I want to perform a factory reset. If I choose No, the phone sends me right to the LG Logo with the error screen. If I choose Yes, it does the same thing. If I plug my phone into my computer while on the white screen asking if I want to perform a factory reset, the device isn't recognized and the PC doesn't see it as plugged in or mounted. I'm not sure what you mean by the timing of when I should try to plug in my device. Thanks again for all your help.

As soon as in the background of the white menu (factory reset) the secure boot appear plug it in. I'm not sure how much usb filter helps you(maybe it does) but try installing ubuntu over WUBI installer so your win remains. Or at least try ubuntu from usb stick. So you can know for sure if it's working.

Hi Sneaky E. I have the same issue you have. I'll be following your thread. If I figure anything out I'll let you know. I am also having an issue getting mine to charge now. Have you tried downgrading your TWRP?

VirtualBox Error
VirtualBox recognizes the device is plugged in, but won't allow me to push the device for use in linux. I keep getting this error message:

I've tried all USB ports, 2.0 and 3.0. I feel like if I can get past this there should be no reason linux can't see the partitions in the phone. Please Help!!!

Ok so thank you for your help so far. I was able to install Linux on a USB drive and ran the commands and pushed appropriate files from there. I pushed all files including recover.img but the phone will not boot into recovery. Please help!
Thank you!

you are not alone dude. i had the same issue since sunday and i have spent almost 46 hours already trying to restore my LG G2 F320S korean model.
i followed that instruction in linux, everything went well but then I ended up with a phone not going past the LG logo. the screen no longer dims like how it used to with the secure boot fail error. again, it stucked at the LG logo and thats it.
pressing the 3 buttons though for 5 seconds shows a white screen with 3 options and a bar code under.
but all of these options will just take me back to the LG logo.
I went to a phone technician today, and they said the doing a JTAG fix is the only way to resolve the problem because after trying to fix it with linux, it is no longer identified by my PC.
what are your solutions so far?
anyways before this issue came up, i tried to flash TWRP using flashify, it failed. then went back up. tried to update the OS via OTA then thats it.
i home someone could help us out.

Been running pac rom, tried installing a custom ROM that was almost stock kitkat for Verizon. Forgot to wipe i think, and now i have been screwed since. Stuck in boot loop. Factory reset can be reached, but screen goes black everytime and doesnt allow me to get into TWRP. Only thing accessiable is download mode. But device is not recongized in adb, only when its bootlooping. But it is recognized in devices and printers in bootloop. New computer also, no RSA authentication, while in bootloop ive tried to adb boot recovery commands, but no authorization. Im completly stuck and have been for days, ive read so many posts but everything i have found doesnt match all my problems. and most people dont read the entire post or problem before submitting a dumb answer, which is a duh i tried that kind of thing thanks for nothing.

vs98010b stock rooted

[Q] Please Help!! Flashed wrong version of software!

Hi guys. I had a 32gb G2 and i was able to root it, upgrade it to 4.4 and use it without a hitch.
Today i got another one (16gb version) and flashed a kitkat rom i had around without stopping to check if it was 16 or 32gb (i forgot they had this difference). Well, now i got phone that i cannot use (im stuck at the SIM card PIN). What happens is that the screen is erratic. i click 2 and it registers 7...i click 5 and it selects simultaneously 123 and so on. basically i cannot pass this screen to enable all the good stuff.
Is there any way i can solve this?
I have a LG G802.

Boot without SIM card, connect to USB and transfer correct ROM. Boot into recovery, flash proper ROM. If you can't boot without SIM card you can probably use adb push to just push the ROM onto the sdcard and then reboot to recovery + flash.

Ok. will implement & report

My problems just keep getting worse.
Since i wanted to go full stock i ended up downloading a kdz file a nd followed the tutorial on http://unbrick.itcse.com/unbrick-soft-bricked-lg-g2/
well...that didnt work. the process initiated and somewhere along the way the app stopped, and the only thing i could undestand was a "EMERGENCY something". After like 1hr with nothing happening, i unplugged the phone and got some corrupted partitions.
I then turned to the tutorial on http://forum.xda-developers.com/showthread.php?t=2582142 ...but damn! i cant reboot properly. now all the phone does is boot up to the lg logo and nothing else happens. windows doesnt detect it, linux doesnt detect it and adb doesnot detect it. am actually crying now....IS THERE ANYTHING I CAN DO TO SOLVE THIS?....im kinda desperate here. This is a brand new phone!

Removing USB connection while flashing

Hi all,
I have a serious problem with my G2 which I could not solve: I used the new LG Flash Tool 2014 with stock KDZ file, everything was going just fine till I received an error message that LG server is not available, I disconnected the USB cable by mistake from my G2 and afterward I saw that it was in the middle of flashing process (12% was completed). I turned it off and tried to reach download mode again and nothing!, I'm receiving the "LG" logo and nothing- the screen goes black (it is still on).
I tried also to connect my phone to the computer- I received a list of 13 "new" local disks "H" to "T", only "H" disk is available and it's showing "image" folder with list of files.
I cannot reach "download mode", nothing is working!
I hope this is not the end for my G2..
please help me
Thank you so much!

If you could receive all those hard disks then you could maybe fix it with linux/ubuntu if you have it. Search for guides to cOpy the neccesary stuff bacK like the bootloader. I can't really help you atm as i am too sleepy.

Thank you for your reply. I found this on the sticky threads: "[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2".
I installed ubuntu and followed the instructions. when I type the following: "gdisk -l /dev/sde" I receive an error message:
"GPT fdisk (gdisk) version 0.5.1
NOTE: Write test failed with error number 13. It will be impossible to save
changes to this disk's partition table!
Problem opening /dev/sde for reading! Error is 13
You must run this program as root or use sudo!"
My device is not rooted, is this the problem?
Please help me!!
Thanks

@NNCa It says you need to run the program as root on ubuntu.
Just use sudo in front of the commands.
You need to type once your password to use sudo, you can't see the password if you enter it for safety I guess but just click enter after you typed ykur password.

Hi,
I powered off my phone by pressing volume down + power for a while ("LG" logo blinked once and phone was fully powered off).
I pushed volume down + power till I saw the LG logo, released it, and pushed again- and finally I reached the Factory Hard Reset screen. I have pushed 3 times the power, and I have got "Factory reset processing..." and nothing is appeared, even when I'm pushing several times on power again.
I guess this is the end of my G2 :crying:
Thank you all for your support, this is an excellent forum!:good::good:

Nope it isn't the end try to install the recovery again or try to push the custom twrp recovery again to the right partition! Dont give up that fast when i hear your things then its still fixable! you already got the factory reset processing so try to Push the Recovery again and search for an guide about recovery maybe Then you would probably get your device fixed.
Just read my things about simplicity so think easy and you can fix it. AND STAY POSITIVE You will repair your phone today :good:

Sorry for late reaction but i needed to think of something. Did you tryed to use another cable? Did you tryed to do it on another pc? Did you tryed to maybe install LG PC suite and see if it gets recognized? If you have the PC Suite you may need to turn it off in the LG flashtool idk. Can you tell us more like which windows you have?

Hi,
I tried all you suggested, however my devide is not recognized. I tried to use the LG PC Suite and to flash by IMEI, however it is still saying that no device was connected.. I checked windows device manager, and nothing changed there.
There is any chnage I can see my connected device? use some tool or another software?

Hi, sorry to say but you have unfortunately completely hardbricked your device. It happened to me too however I was able to get it replaced under warranty at no extra cost.
What happened was that when your phone was still detected by linux, you had a chance to recover by flashing the correct partitions to gain access to download mode and from there, flash a KDZ to go back to complete stock. However, the files you used were probably incompatible with your variant which has now corrupted your bootloader sequence. I suggest you read this reply by fizzy177 as well as the rest of the thread: http://forum.xda-developers.com/showpost.php?p=51522304&postcount=118
So right now, you cannot do anything as you have already found out, no computer will recognise that your phone is plugged in. Your phone fails to boot when you try enter the download mode and it just freezes on the splash screen which looks like this: http://www.lg-phones.org/wp-content/uploads/2014/03/image2.png
What's meant to happen is your phone should load past that initial splash screen into this http://www.androiddunya.com/wp-content/uploads/2014/01/LG-G2-DownloadMode.jpg which accepts KDZ flashing and warns the device has been rooted.
So it's a blessing that your phone cannot boot as LG cannot find out you have voided warranty and you will be able to get a replacement free of charge.

Issue was solved- device was fixed under warranty
Hi,
I just want to update you all that my device was fixed under warranty! (motherboard replacement)
Thank you all for help and great support, this is a great forum with great community :good::good:

Hello
From past 2 weeks i am wondering on internet for a solution . Hours and hours of surfing and articles but still
Hope some one solve this issue.
Okay. First i m using LG G2 F320 K update to lollipop . Non rooted. It was working fine . I can transfer files in MTP .
But about a month ago i get an update for my phone . And after some days i need to transfer some files to my phone , i wonder when i connected my phone to computer nothing happened . No notification on mobile for changing PTP MTP option . Also nothing happened in Computer device manager..
From that day i am unable to connect my phone with windows 10. It always charging mobile.
I uninstalled all drivers in device manager and installed from LG website. I updates windows N and NK MTP update from windows for windows 10.
I changed different data cables and different computers and different ports . All stuff i can do. Still no luck.
When ever i plug USB data cable it always put my Mobile on Charging . No notification on Mobile. Also i go in setting > storage> and there is no option in upper right corner to select USB PC connection .
I am in developer mode and debugging mode is on also. Also USB tethering option is Disabled .
Kindly some one help me regarding this.
LG G2 F320K updated to stock Koren lollipop 5.0.1 . Non root.( i updated lollipop in April 2015)
Issue i am facing is no notification for Charging/ MTP/PTP Usb Debugging on mobile notice bar when i attach my phone using USB cord with computer. Also in computer device manager nothing happen. Even i checked on windows 10 , 8.1, 8, 7 .
I remember it was working like charm 4 weeks before I can change MTP PTP or Charge only mode by selecting notification when i attach it to my laptop. I can transfer files can use LG PC suit .
Then i received an software update like 40 mb and i updated my mobile. That i remembered.
After that 2 weeks before i need to transfer some books from laptop to my mobile. When i plugged my device there no notification to select MTP mode . Also there is nothing happened in my windows 10. I looked in task manager. No yellow icon in computer task manager for driver thing.
Laptop is just silent and mobile is just on charging .
Then i go to setting in LG and looked for USB PC connection settings. I wonder there is nothing . Settings > storage > 3 dot in upper right corner.. it suppose to be there . But here is no 3 dot in storage. Then i looked into share and networks in android setting and i found that USB tethering. But its faded mean it is disabled and i am unable to use this feature also.
I tried on different computers different cables , original, but nothing. Always when i plug usb mobile went on charging and in all computers nothing happen in device manager.
USB debugging is on.. I factory reset device 2 times. but useless. Also i uninstall all drivers from my laptop and then reinstall drivers from LG website also i tried google drivers , ABD, different ports. Nothing nothing happen.
Also now if i try put mobile on download mode by turning device off and then push + vol button and then put cord in mobile . No download mode also it went on charging. Well charging from laptop or from charger is okay.
Hope i explain all.

[Q] [HELP] LG G2 D802 in coma - Really Deep, Hard and Seriously Bricked

A few posters here claim that the G2 is unbrickable - but I think I can challenge that. It started off with me wrongly flashing the Cloudy ROM 3.0 - what I didn't realise only till later was that it was intended for the Korean variant of the G2. Dummy move indeed.. I had previously taken the necessary precautions and took a full titanium backup and ROM backup onto a USB drive via TWRP - I previously ran Cloudy ROM 2.2 with Dorimanx Kernel on KK 4.4.2.
Right now, the phone doesn't seem to power on via buttons. When I plug it to the PC via the USB, I get "QHSUSB_BULK" as an unknown device only.. no black screen while on, no drives or COM port.
First off I want to be clear that I know I and only I am responsible for bricking my phone - The reason I'm in this mess is completely down to my stupidity, and trusting 'educated guesses' instead of confirming specs black of white. Just wanted to be clear in case anyone gets the wrong impression.
So this is more or less the sequence of events;
1. After flashing, I got stuck in fastboot mode.. (can't find the link) I followed one post where I needed to flashed .img files via the Fastboot CLI (similar to ADB). I used the images from the LG G2 D802 16GB in europe. source.. It was a toss up between the EUR and non EUR, and so I made the first of my so called 'educated guesses' that sent this phone deeper into the ground.
2. Something went wrong as when I rebooted the phone (had no idea what had gone wrong at the time), I got no logo. After some time, I noticed the screen on with a black background. when plugged into the pc, the QHSUSB_BULK would appear and with it a bunch of drives that Windows thought needed repairing. so I followed This .. I installed ubuntu, booted to terminal so I don't get those auto discovery pop ups, I used the images recommended there for my device (again, it seemed to make sense to use the same that the OP was using for my LG G2 D802 16GB in europe... After I rebooted, it was to my horror that the screen didn't even turn on, with no drives being detected via USB.. just the QHSUSB_BULK. This is what made me realise that the culprit was most probably using wrong images rather than improperly executing the instructions.
3. I opened the phone and tried shorting some capacitors where I'm supposed to see the drives again to no avail. I even tried shorting the capacitors ends as described here to no avail. I done a good full hour shorting the hell out of those capacitors (the post says to keep at it till it works cos it can sometimes be a bit tricky) but I saw no change. I would like to try the DL mode described there but I can't figure out what I have to ground from the images shown in the post regarding the "BOOT CONFIG".
This is basically the state the phone is in at the moment. so to recap:
No bootloader,
no recovery,
no fastboot,
no download mode,
no drives when in QHSUSB_BULK mode,
no COM port.
From the multitude of unbricking guides here, I gather that I either need to see that bunch of drives again when via USB or a COM port. I tried installing Qualcomm drivers, thinking that if the pc recognises the device, I might get the pc to identify the COM port, but the driver couldn't be installed for the QHSUSB_BULK device (got some error.. I can update this post later).
I tagged this post as a question.. i'm sure there's a question here somewhere...
HELP?!

You can ask @somboons
he came from deep hard bricked.

When I first tried to enter QHUSB_BULK mode on mine, I took ages. Seriously, ages. It kept not showing the drives. Important thing to remember, in my opinion, is to use Linux (latest Ubuntu in my case). If you keep trying, eventually they will pop up for a split second. I can't remember how I did it, but you have to use a partition tool, I think, to get it to freeze the positions of the drives. Then, once it's 'mounted' them, you can try (and keep trying) to flash to each partition.
Mine was well and truly screwed, so I flashed a blank partition table on, then flashed each image onto that. It took a lot of trial and error, though, because it kept not showing the drives.

Mine was exactly the same I also had a blank partition table.. Anyway just keep trying because It took me a while to get mine working.. I was trying to short the capacitors but it seems to be quite hard sometimes especially if you aren't carefull.. Because you can start to mess with the soldering of the capacitors and it'll be harder after that.. It happened to me..
Anyway here's something I've wanted to ask everyone, after I sucessfully put my phone back to life, it seems like the middle button isn't working, the LED and the volume rockers are fully working, but if I ever press the power button after some time it shutdowns just like if I pressed and hold for a while, has anyone got this problem? It seems like the flex cable or something is damaged but i wanted to be sure it's really damaged or just something I could solve.. thanks and sorry for the off topic..
