My device is detected as qhsusb_bulk on windows xp but not on Linux Ubuntu do i need to install some driver? i m using Ubuntu 12.04 LTS on USB stick. do you guys just detect qhsusb_bulk automatically when plug in Ubuntu ? please help
[G2 General] Partager.info:
Are you using ubuntu on virtual machine?

anyway if you use virtual machine just open it in full screen and plug your phone.

If you have installed ubuntu directly on a computer then power off your phone and plug it to your computer. keep doing it untill you get it detected.

You can also try a factory reset by unpluging your phone and turning it off and holding vol up + power bouton, then release it once lg logo appears then hold them again untill you enter into factory reset mode. and foolow instructions in the screen to make a factory reset.

Good luck
[G2 General] yurileung:
no, just used boot able usb stick.do i have to use using ubuntu on virtual machine. some how it cannot detect on ubuntu, before my phone was able to boot only LG logo with secure booting error, then the screen goes black while the phone is still on. but now there are no flashing logo and the screen is not even turn on black, is that mean this is the worst case ? however the phone is detected as qhsusb_bulk on windows xp so why is not in ubuntu ?? i really want to fix this phone if i can. by the way, my phone model is F320L
[G2 General] Partager.info:
Well just open the virtual machine window in full screen mode and plug your phone to your computer. it should be detected as qhsusb_bulk in ubuntu. if you keep virtual machine window opened just like any other window in your win xp, 7 or 8 your phone will be detected in windows not in ubuntu.

don't forget to install "qualcomm hs-usb diagnostics 9006 drivers" for windows. make a search on google.

When you install the drivers restart the virtual machine and follow the guide above.
[G2 General] Dr_Nikiforos:
i did everything of first post and thank you very much.

But my problem now is that i can boot only on twrp recovery.

[G2 General] cccho:
In my case, In ubuntu just open terminal windows and type

ls /dev/sd*

It will show a lot of device connected. Then try follow the guide in p1.

In Windows, when you plug in it will coming up alot of windows ask you to format. Don't press format, just cancel it. Then boot to ubuntu and fix your problem.

Hope its help. Leung, are you HK's ?

How do the instructions differ for a D800 AT&T phone and does it matter if I use VMWARE 9? I am a beginner at doing all of this, I mean that is how I got to this point. If somebody could please help that would be great. I would even be willing to PayPal some cash if I get it fixed. Thanks.
[G2 General] yurileung:
Yes, i m in HK, Today I have been bringing the phone trying to get it fix at sincere house in MK at 1F where the shop they repair mobile phones.

before my phone still can load the logo and with sign of black light, and pop up driver to format. now its just worst. I think that stupid guy must be formatted the drivers. and now my phone does not load the logo and with sign of black light what so ever. I cannot believe it what he had done if he doest know what to do.

now my phone just only shows as qhsusb_bulk on windows xp but not on Linux Ubuntu. therefore i think this is the worst case for me. i really dont kow what to do. does anyone been fixed even just shows as qhsusb_bulk ??

Hello,

Hopefully someone can shed light on my problem.

I had the same problem as described in the first post. This is what I did:

- Follow instructions --- OK

- FIx "security error" --- OK

- Install TWERP recovery & Root --- OK

- Install ROM--- FAIL, tried with twerp, every time protocol error or cashe wipe error. I also could not mount memory, do used adb command sideload & push

- Installed CWR --OK

- Wipe Cashe and factory format -- OK

- Install ROM ( Cloudy, 1.5 gb) -- OK

- After I turn on the Phone, it goes directly to CWR, it does not boot into OS Android.

Any ideas? :cowboy:

Thanks in advance.

You need to turn off the phone completely - press the Vol+ and insert the usb cable. Does it show multiple disks ? if it does .. it is a good thing (this is the QH USB 9006 error)

[G2 General] habeck.colibretto:
You can connect to the phone (cause you can see the structure of sdb) - that's good. But you DON"T HAVE "/desktop" directory. So you have your IMG files (which you need to recover your phone) in other location. Don't ask us where. Just locate them and put proper directory (red bold) here: dd if=/home/med/Desktop/sbl1.img of=/dev/sdb2 and don't forget to put the right name of IMG (because you have downloaded file 2-sbl1.img not sbl1.img).

HELP

Please help, i have D800 which was accidentally flashed to D802, the phone was stuck in fastboot mode, i tried a method with flashing laf.img and some other img files via fastboot and the phone got stuck in qhsusb_bulk mode, so i tried this method with ubuntu, pushed the partitions and a twrp recovery to the phone, and now the phone won't boot to recovery, instead it says something about secure boot and the screen goes black, and is not detected on pc. The phone also boots and displays the LG logo, and restarts after a few seconds. I can enter download mode, and the phone is detected correctly, but lg flashtool won't flash the phone because it cannot read the model at all! I also tried LGUP_8974.dll but no luck. And i also lost the qhsusb_bulk mode, so it seems i'm stuck now?? Please help..

[G2 General] sandys1:
The flashing of IMG files is correct - but you have to flash all the IMG files. Your problem might be that you have some partions of d802.

---------- Post added at 05:10 AM ---------- Previous post was at 05:05 AM ----------

Follow the steps in the first post. Flash all IMG files and then try.

Once you are in download mode,then you can flash again.

tried 3 virtual machines, no luck

I tried with Ubuntu, it gave me about 4-5 /dev/sd* options, but they did not change when i plugged and unplugged my bricked G2.

then tried SLAX, not sure if i installed it correctly, because it only gave me 1 option...

Now i finally tried KNOPPIX, and i got all this:

[IMG="knoppix"]http://pelefix.co.il/misc-useful/knoppix.jpg[/IMG]

but when i plug and unplug the bricked G2, it doesn't show me any other option /dev/sd* options, meaning it doesn't recognize it.

I tried different USB ports, nothing..

i can feel the device is heating up a little bit when it stays connected.

any idea?

Your screenshot did not come up correctly.

Once you connect to Linux, immediately run the command "dmesg" and copy last 10 lines and paste here.

I also recommend unplugging the battery and connecting it to computer

Yet Another Bricked G2

YABG, guys. Sorry for a bad English, not my native language. I'm using my g2 for about half a year and it's certainly The Best phone that I have ever used. So, today I bought another second hand bricked g2 for my girlfriend for a New Year (yeah, I'm absolutely broke right now and I was hoping that I was gonna deal that brick problem). Signs of bricked phone is:

g2 itself is not react at all besides warming on charge (no led or screen flashing, download mode, nothing)

PC is seeing phone memory like a lot of local disks.

add: screen is flashed with black color. Only black color and nothing else, no indication. When I'm holding power button for about 8 seconds it'll completely off. Then again, if I connect phone to PC or charger it flashed with black

add2: and yeah, in Windows it shows like QHSUSB_BULK

So, I'm trying to use ubuntu-method, VMWare and 14.10, and after plugging phone to PC I hear windows connects and disconnects local disks sounds and then if I repeatedly push

ls /dev/sd*

it's coming only sda partitions, but in about 1 try out of 20 (when its connecting-disconnecting) I can get all 36 sdc (in my case) partitions visible, but in next moment it's again only sda and I can't proceed.

What can I do in this hard situation?

If you can help me, guys, I'd be really appreciate. And I'm hoping to fix this beauty till January, since it's should be a present. Thanks in advance and have a good day. Or night.
[G2 General] pvlkrpv:
Plus if I'm repeatedly pressing gdisk -l /dev/sdc now in 1 press from 30 I'm getting this new error. In addition to 1 time out of 20 when I'm getting normal list of 36 partition on my sdc.

add: and while I connecting phone to a ubuntu-driven PC (live usb) it's flashing with black screen and turning off, flashing with black and turning off again and again. And in some times I can get my sdc partitions but most time I can't.

I hope that I described my problem well and also hope that someone already had that problem and deal with it.

[G2 General] danielsigma:
Yes I had the same problem... please search some posts in this forum, I already described it.

My advice again: try OTHER Linux, not Ubuntu.

I fixed my G2 using Linux "knoppix". This Linux can fix the connection between phone and PC. When I used it, I could get sdc partitions all the times.

Search for it - knoppix - in Google, install it and flash the phone, your G2 will revive.

Danielsigma is right. Ubuntu didn't work for me either. Installed Knoppix and now my phone is working again. So, thanks for that Danielsigma

Something happened... but it went worse

Hi Guys. First of all, thank you very much Partager.info for this guide, it helped me a little... but I think situation got worse:

After I've followed every single passage (copied every file inside the lg) I just turned off the phone (unlinking the usb cable) and then turned it on... Lg Logo... And nothing more.

Ok, there's no need to panic, let's try to do a hard reset: Tried, went into the hard reset screen, tapped on the power button a couple of time, resetting... And Stuck for the second time, inside that damn hard resetting screen!

Now I can not interface the smartphone with the pc anymore: every time I try to plug in the usb cable, the lg logo pops up... and nothing else happens, no usb connection, nor some error or sign of life.

Can I do something for my Lg? Or is the situation completely lost? Thank you in advance, fellow gentlemen :D
