Hello, today due to misleading tutorial I erased all partitions on my LG D800 with

(tutorial - step 3. - http://xdaforums.com/lg-g2/general/mega-tut-how-to-fix-bricked-lg-g2-t3055033)

I erase ,but do not flash anything in place, so after reboot, my phone stayed with no sings of life - black screen.

When connected with WIN7, in device manager I can see QHSUSB__BULK with exclamation sign. (windows cannot find and install correct drivers)

I tried [FIX][FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2 ,but Ubuntu do not see my phone "ls /dev/sd*" gives me only my HDD partitions sda and USB LiveCD sdb. When I tried "ls /dev/s**" it finds dev/serial , when phone plugged in, when I run command "ls /dev/s**" without phone connected there are no dev/serial.

So can anyone tell me what I should do to get my phone back to life?

D800 freezing and rebooting

Hi everyone,

I have been trying for two days to reset my phone. I think this might solve my issue or perhaps didn't fix it for others?

My d800 phone has twrp and cyanogenmod 12 but is freezing and rebooting constantly into qhusb bulk mode with yellow mark in windows device manger and nothing in linux. I tried formatting everything using twrp and also tried lgflashtool restore to kk att oem rom. My linux detects the phone when its on only as others pointed out but there is a folder "0" with old oem rom files and others are for cm. I am assuming that twrp only format a small part of the partitions.

Can this fix the freezing and rebooting and why doesn't linux detect my phone when the cell don't boot into cm?

thanks!:confused:
[G2 General] wulsic:
about that yellow mark maybe some driver problem or perhaps another qhusb mode. So you can still boot into twrp or not? If so what you could maybe try is to flash an full D800 stock rom which also flashes the bootloader etc through twrp and then see if stock works properly now. I have no idea why it is rebooting constantly into qhusb but did it worked before fine? What happend that it was going to reboot constantly into qhusb?
[G2 General] aziz07:
I was charging it and the battery jumped from 58% to 100%; cellphone rebooted in qhsusb_bulk mode with a black screen. Something might be shorted inside. I already used lgflashtool to restore completely to stock but freezing and rebooting still occured. I did manage to get in twrp without rebooting. Flashed jb bootloader and kk baseband on top of pa lollipop. Now the phone doesn't power up but is detected as qhsusb_bulk in windows device manager with a yellow mark, where can I find the drivers?

I am using lubuntu linux, I will try with ubuntu live but should be the same.

I found the qhsusb driver online but didn't use it as disk management detected the partitions with the yellow mark in device manager.

btw there is also a way to this in windows with disk management:

edit: Now I can enter download mode but lgflashtool won't recognize the device and only a B72 code is displayed:

[G2 General] aziz07:
Finally fixed! The trick was to fool the lg app with a modded dll found here as I erased every partition on the phone.

Flashed oem tot and now installing twrp and paranoid android+pico 42mb gapps 5.1.1 ;)

No freezing so far! Seems that the short circuit damaged the core boot and id partitions. With lgflashtool, I was able to flash original tot file on a fresh partition which solved the rebooting issue.

Now Its time to fix the digitizer's two broken lines. It was dropped onscreen from more than 2 meters and I was sure it wouldn't boot as it had no case. Never opened an android yet, only iphones lol

Too bad, my lg g3 is on the way and I will prolly gift this g2 to my brother to replace his aging/partially broken iphone 4.

Paranoid android G3 be it ;)

5.5 inch and 1440p should be better for reading medical books. :D

In case anyone need the modded dll to fool the lg flashtool, scroll down to AT&T section, the dll should work for all models:

hxxp://xdaforums.com/showthread.php?t=2432476

If you can't access download mod, follow the partitioning explained in youtube and xda thread to restore it, then follow this. If stuck in fastboot mod: http://xdaforums.com/showthread.php?t=2477595

If everything fails, you have to manually open and disconnect the battery and follow the steps in the xda thread posted in OP here. Otherwise, try your luck with jtag and/or with lg/provider.

thanks xda :cool:

I would have donated for the dll but I am not working and only a med student for now -.-

[G2 General] packyman:
hello

situation1: I have a D802 16GB Germany 20H installed, it runs fine but without able to root (loki_error) and without download or recovery mode....

USB Debugging is active, despite, I'm not able to adb sideload oder push anything because I get the "error: closed" or have no permission. If I install and start recovery I'm not able to mount /sdcard. In Windows 8 its connected as "AndroidNet Sooner Single ADB Interface".

For this reason I searched another way to get a working recovery or downloadmode.

situation2: I do the hardware mod for GHUSB 9006 and copied the *.img to the phone incl open twrp.

Now I had a bootstack but was able to reach the recovery (still unable to mount anything) and download mode, but I can't connect to download mode,..... its dead.

Now I tried to unpack another kdz (30b) and merged the system.bin files to one together. The File size reached now 3,2GB. The system partition is only 2,7GB big.

WHAT NOW?! How can I get another rom into the phone. I know I could copy the old 20H files to the phone but then I were in state 1 (working rom, without downloadmode or recovery).

Who can help?
[G2 General] aftabalam8c2:

It'll boot into rom but after being running for about 1 min it says invalid battery and shuts down .

I can manage to get it into download mode , but it seems the computer doesn't recognize it .

I tried Ubuntu , but I can't get the os to run any sense .

I think I flashed a European Rom somehow . Not sure how to fix this now. I hate to throw office away , it has to be able to be fixed .....

Anybody know what I can do ?
[G2 General] wulsic:
Your download mode might be bad, so it's also not recognized in device manager? Can you root your phone perhaps without download mode? Which version are you now at? I assume it's not the battery and if we can't root and can't get download mode to work then I might have another method for you but that's only if everything else failes.

No need to throw it away, I can assure you you will have your phone soon booting properly. I can help you with that. If you want instant communication then you could contact me on hangouts, skype, or facebook(my android fb acc) or via private message from xda but I might not respond to that immediately.
[G2 General] rodpgfx:
Thanks alot Wulsic. I can contact you on hangouts. What's your ID? I won't be around till this evening. (5 hrs) working right now.

I believe the rom was for 4.4

Hi, thank you for this tutorial. It was helpful. I did everything you said. Now the phone boots with the LG logo. However, I can't get into TWRP. When I try to, it asks me if I want to factory reset. When I say "yes," it says it's factory resetting and the screen goes black. It's like the TWRP file I uploaded via ubuntu isn't working. Any suggestions? Thank you for your time and assistance. I appreciate it.
[G2 General] wulsic:
Hmm odd. Perhaps not the proper files for your phone? So you don't have any other way to get into download mode or fastboot mode? If you can't enter these 3 then I have to refer you to the hardbrick fix guide in general which requires opening your phone. It isn't that hard but you must try to avoid carpets and static elektricity so I suggest to touch something metal before you start with it. When you need help just contact me I can help you with that as I also done it before.
[G2 General] halebopper:
Ok. I followed the instructions here (http://xdaforums.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404), but I'm still not having any luck. Here's the history. I have a D800 AT&T model. I was updating the phone from D80010d up to D80020c, update by update. When I got to 20c I ran TWRP installer to install it, but when I rebooted, I got a black screen with no logo, no recovery, and no downloader.

Then, I followed the directions in this post and was able to get the phone to at least display the logo on boot, but I couldn't get past that. When I tried to get into recovery, I was faced with factory reset. However, after agreeing to factory reset, it went to a black screen and hung there.

I've tried opening up the phone and using Ubuntu on VMware to push img files to the various partitions, as well as different versions of TWRP. However, I haven't been able to get past where I left off. I've been at this for about 15 hours and am giving up. I need help. Any insight you can share with me would be much appreciated.

Thank you in advance for your time and assistance. I appreciate it.

I'm having trouble finding a way to fix this:

I have the same problem as this guy

http://xdaforums.com/show....php?t=2704519

I applied a one click root+twrp. Something went wrong and soft bricked my phone.

It boot loops into twrp but twrp's gui is unresponsive. Have got it to factory reset in twrp get but i get "can't mount /data" in red text. I can get into download mode. TOT flash to stock method kind of works. It runs through the process very fast and flash tool returns:

skip system partition

Skip aboot Partition

Skip rpm Partition

Skip boot Partition

Skip tz Partition

Skip misc Partition

Skip persist Partition

skip cache partition

est... for rest of partitions

Finishes the process and phone reboots back into boot loop to broken twrp

the tot and dll files are fine cuz i used them to flash it earlier when i got stuck

I can't get the KDZ method to work. Does anyone know what's wrong

Is there a another way to replace the partitions manually? maybe a linux way? I'm still very noob, hitting a very hard learning curve

Can't get into TWRP

[MENTION=5084584]Partager.info[/MENTION]

Thank you for dedicating in a lot of effort to this.

My phone is LG G2 D802 32GB; I found 32GB-related files from somewhere in the XDA and successfully pushed them into the device as you suggested. As for the TWRP, I used the one you linked and pushed it into the recovery partition. However, for the life of me, I just cannot boot into TWRP. I hold down the power button for a long time and it switches off eventually (right after flashing up LG icon). Then, I hold down the volume down and power buttons but it just switches on and resumes to the black screen. I've read it somewhere in this thread that plugging in the phone to charge all night and then trying it again in the morning could work, but it doesn't for me.

Is there anyway to force the phone into the TWRP?

In case anybody wants to know, my download mode doesn't work. I just shows the initial icons and wouldn't proceed any further (hence why I had to resort to this process). Thank you in advanced for any suggestions and advices. I apologise if this was already asked and answered, I just couldn't find it. So, here goes my very first post.

EDIT:

I've managed to fix this now. Learnt the right way to get into the recovery from here http://xdaforums.com/showthread.php?t=2534981 However, my download mode was still broken so I did some digging around, and found out that I could push the laf.img to fix it. So, adapting the syntax that OP used, I did the following and it worked like a charm, though I don't know if that's the right thing to do.

dd if=/home/<user>/Desktop/laf.img of=/dev/sdb23

how can I deal with this? thanks.
[G2 General] Godspell:
I'm quite sure this is because Linux isn't detecting your mobile. Are you running it within the Virtual Box by any chance? I had the same issue, Ubuntu won't detect it within the VM when Windows (the host OS) did but couldn't comprehend it. At the end, I ended up installing Ubuntu side-by-side with Windows. The device was detected by then.
[G2 General] 2anyone:
thanks for your reply, Im running it in solid installed Ubuntu.

tried: ls /dev/

it shows lots of devices, comparing the devices between Plugin and Pullout, I found, when plugin, there are 2 device added:

serial

ttyUSB0

tried: gdisk -l /dev/ttyUSB0

shows me:

The specified path is a character device!

:(

Plugin this phone to Windows, it shows "QHSUSB_BULK" in Devices Manager.

Any advise could let Ubuntu detect this phone? thanks.
[G2 General] :
I have just recovered after a catastrophic near heart attack using a variation of this method. - The warnings on this page scared the pants off me as they said "You must use the img files that correspond to the ROM you have installed before getting the problem to avoid breaking your phone" for two reasons:

1. I was previously running CM12

2. I had .bin files

But I was determined!

So I had a handy laptop and Ubuntu Live USB so booted those up

Firstly, plugging the phone into the laptop in this state was a nightmare for popups, but I managed to fix that with "gsettings set org.gnome.desktop.media-handling automount false" - NOTE: NOT sudo - to stop the devices automounting continuously

Successfully running gdisk gave me the list of devices - about 30!

Then I started following the original instructions and having no luck (using a deconstruction of the 20d ROM) - Deconstructed via: http://xdaforums.com/showthread.php?t=2600575

I decided to download the 10d ROM and extract that to try again. This time there was also no luck on the reboot either. So accepting my fate of new phone I took a "What the hell" tactic;

-- Go through the list of extracted parts (excpet system) and flash ALL OF THEM --

I'm talking aboot, boot, cust, dbi, laf, modem, persist, recovery - not the openrecovery!, rpm, sbl and tz!

Flashing each one to it's corresponding /dev/sdc##

This reboot lead to being faced with the Firmware Upgrade screen

*Queue elation*

From here, I used the standard LG Flash Tool 2014 and the 20d KDZ File to install stock LG Software

I hope if anyone else is having troubles with the method this might be something useful.

Massive thanks to OP though for getting me 80% of the way! I never could have got this without you!
[G2 General] Godspell:
The QHSUB_BULK was showing up in the Windows Device Manager for me as well, along with a bunch of msg prompts (suggesting me to format the partitions). Hence why, I went onto Ubuntu (first VM and then, on proper install).

Anyway, I'm afraid I don't know what to suggest...maybe you should also post this on Ubuntu forums?? Can't help to ask, right?
