The original post says using the Linux solution is the only fix but that is not true. I had the same problem and fixed it in Windows doing this:

- Power off G2

- Plug G2 into computer

- Press and hold vol up + power button until it turns off

- Release power button BUT still hold Vol up until G2 enter to download mode

From there I was able to flash using the TOT method and a generic dll. I hope this helps someone.

You have to extract KDZ into DZ, Then from DZ you can extract these files.

They are in .bin format. You have to manually change it to .img

Phone went "Unknown Device"

Hi,

I tried the procedure of the original post here and managed to push the files to the phone but I made a mistake at the end which I'm not sure if damaged the phone.

I downloaded the required sbl1, aboot, rpm, tz and recovery for my version (d800) but the recovery was a zip file and I copied that instead of the .img file to the phone. After that is not recognized by linux at all and when I plug it to windows is being recognized as a "Unknown Device" in the device manager (see attached image). Also the phone is completely dead as I haven't been able to turn it on using all hardware keys that I've seen.

Anyone knows what can I do? Is there a way to run the process again or get linux to at least recognize it ? What kind of brick is this?

Please help
[G2 General] amper20:
what about that??
[G2 General] emoxaph:
i only see /dev/sda /dev/sda1 /dev/sda2 /dev/sda5

how do i fix this issue?

I also can not see my phone in ubuntu. although when i try to add a USB in VM main screen it shown my phone as QHUSB
[G2 General] bitdomo:
do this command when the phone is connected: lsusb

post the output here
[G2 General] emoxaph:
Here you go
[G2 General] bitdomo:
Phone showes up as Qualcomm diagnostic 9006 mode. Can you do an: ls -latr /dev/* command? And post an output of the last few lines?
[G2 General] emoxaph:
these are the last few lines under /dev/char:

that arabic part says "april"
[G2 General] bitdomo:
Something ia wrong, why it is the /dev/char folder?

Go type this: cd /dev

Then ls -ltr

Post screenshot.
[G2 General] emoxaph:
this is what it gives.

would it help if i told you why my phone got hard bricked?
[G2 General] bitdomo:
It would clear up some things.

Disconnect the phone from virtual box and connect it to the host PC what new device you see in device manager and is there any new disk showing up in disk management.
[G2 General] emoxaph:
i rooted my phone using IORoot. then i installed TWRP using TWRP manager. it said that it will now reboot. but it never did. i cant get into download mode or fastboot mode. nothing. just the screen lights up as a blank screen when i connect it.

also when i connect it, around 15 disks show up on my windows asking me to format it. and in the device manager it shows up as "unknown device"
[G2 General] bitdomo:
Then those disks should show up in ubuntu too. Maybe it is just the incompatibilty of virtualbox ( I always used vmware) or some driver issues of your windows.

Here get the drivers https://mega.co.nz/#!K0pV2BTC!joq09epSiDWWu6s1lVjTcnNfB1da0YS6p5VjFNZ9US8

Before instaling them make sure you turn off the driver signature enforcement and the phone is connected to the HOST os and not to virtualbox.
[G2 General] emoxaph:
i'll try that. if it still doesnt work i will give it to the shop to fix it. thanks a lot for your help.

Please help me???
[G2 General] SnekTheTenk:
Rom works normally only can not get into recovery and download because I tried to flash TWRP 6.0.3.3 with flashify.

Will it work when flash a recovery for kitkat (when one comes out)?
[G2 General] HighlanderZA:
I'm hoping so - but from my reading, it looks like the phone will have to be restored to JB stock with the LG tools and then updated with specially prepared KK ROMS and a special KK recovery. I might be wrong, but that is my understanding of what I've been reading.:eek:

My personal advice right now - stay on JB stock if that is where you are - ROOT maybe, but DO NOT install a custom recovery.

Wait for your SP to provide KK via OTA

------------------------------- OR -------------------------

Wait for the KK magic to come from the devs on the LG forum.

I think patience will prevent a lot of heartache and panic. :eek:

As an aside - I have KK on my Nexus and it is a very non exciting wow and not the WOW I was expecting.:rolleyes:

Just my personal opinion of course - not to be taken too seriously. :o:angel:

[G2 General] Absinthena:
Basic Question

I have a stupid question - I tried to scan all the pages and I just end up more confused sometimes. I do not want this mess happening to me.

I have a Sprint G2, rooted after ZVA over the air update. I haven't installed a custom recovery or anything else because I don't feel like I've read enough yet to proceed comfortably.

With this KitKat business coming out... Does it force it onto your phone? And am I going to run into a problem, in my current situation, if that happens? I saw someone mention that if your phone is rooted to NOT install a custom recovery if you're anticipating an update. Is this true?

Is there a up-to-date site on dates for Sprint OTA G2 updates? :confused:

[G2 General] bitdomo:
When you shorting testpoint it goes to qualcomm qdloader 9008 which is good so you could use boarddiag tool. Get a tot file for your device and go to this thread. Open the OLD OP section and follow the instructions. It for Nexus 5 but the stepps arent different for G2, you just have to use a tot file for your device and select G2 as AP chipset.

Btw when you done that disconnecting connecting thing you dont get qualcom diagnostics 9006 mode to see the partitions on the emmc as I see from the logs. You get probably get LGE AndroidNET or something similar device.
[G2 General] aceperry:
Thanks for the reply bitdomo!

I'll try your suggestions tomorrow when I'm less tired, not really a windows fan, and will need all of my attention to work with it. Not sure what you meant by "Open the OLD OP section", but I looked at the page you linked. It's similar to a procedure that I tried earlier without results. (I didn't use the same boarddiag tool, and some things were a little different)

The "LGE AndroidNET" device is what I see under windows. I guess that's supposed to be normal, something that I hadn't read or seen mentioned in these forums. Maybe I haven't looked enough (?, there is so much stuff about this issue)

Quick question about the procedure. Everything I see about shorting the test point requires the battery to be disconnected. After successfully setting the phone into qhsusb mode, you have to reconnect the battery. After reconnecting the battery, you're supposed to disconnect the USB cable and then reconnect it. Then you're supposed to do the flashing. Most instructions imply that you do this with the button disconnected, so when you reconnect the USB cable, you can't really put the phone into download mode. Does any of this look like it's correct?

Again, thanks for your time and help.
[G2 General] bitdomo:
By OLD OP I meant that go to the bottom of my post and click on the show content button under the text "Old OP", because there are the instructions how to extract tot and etc, and I was not sure how familiar are you with boarddiag.

[IMG="http://kepfeltoltes.hu/150406/1371014494Untitled_www.kepfeltoltes.hu_.png"]http://kepfeltoltes.hu/150406/1371014494Untitled_www.kepfeltoltes.hu_.png[/IMG]

Just do the shortcircuiting without battery then check if the phone got into qualcomm qdloader 9008 mode. Connect the battery then use the boarddiag tool I linked. That is known to be working. After boarddiag finished assemble your phone and go to download mode then flash the tot file with lg flashtool, or a kdz with lgflashtool2014.

Which files to flash?

Device was on stock 4.2. I rooted and flashed from recovery a stock 4.4 ROM, and then a 5.1 CM-based ROM ( http://xdaforums.com/lg-g2/development/romkernel-sabersunset-1-2-t3028536 ), with Kitkat baseband. I tried to flash the LG D802 30a firmware ( http://xdaforums.com/lg-g2/development-d802/rom-stock-30d-flashable-zip-t3070383 ) from recovery. The Aroma Installer was stuck for several minutes at "Extracting files.. 10%", so I restarted the phone, and now get the LG boot certification verify error. Tried to get into recovery and it showed the stock recovery and asked to format device, but that does not do anything.

I'm not sure which ROM to extract the img files from. I read the instructions which say we have to use the files from the ROM that was installed before the issue happened, so that means the CM-based 5.1 ROM, right?

It looks like that ALMOST worked. Except for a serial port failure which I'm not sure what that means.

This is the Device Manager window:

LG Driver:

That's all that I can think of that would be relevant. Otherwise, I'm hoping it's a straightforward tweak to get it done. Thx.
[G2 General] aceperry:
OK, I figured out that the driver should be running, but it wasn't due to an unsigned driver. So I GOOGLED it and found a webpage describing how to get around the unsigned driver (temporarily)

https://www.raymond.cc/blog/loading-unsigned-drivers-in-windows-7-and-vista-64-bit-x64/

So I finally got the bootimage downloaded to my phone, thanks to bitdomo by following his very nicely documented and explained instructions.

Next step is to reassemble the phone and flash the image back in. I'll report how that goes when I attempt it tomorrow. Hope this helps others. And thanks again to bitdomo.

Finally got my phone back to normal, thanks to all of the helpful people here. It took a long time because I was hesitant to take my phone apart, which was critical to getting it in a state to be able to flash a new bootloader and rom. Anyone who can't get ubuntu/linux to recognize the phone's partitions should seriously consider the "short circuiting the testpoint" method as illustrated in this thread:

http://xdaforums.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404

At least for my phone D801 (T-Mobile), once you get it into qhsusb_bulk mode (either 9006 or 9008), you can then follow the other guides for unbricking your phone. Until then, it didn't work for me.

I tried flashing with the LG Flashtool 2014 and a kdz file. This didn't work for me. Next used the tot method which worked.

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

It booted up with the original rom that the phone came with, then I used the software update mechanism to update to the latest available firmware. Now the phone works great.

8- Screen is blinking in black light while connected to PC using USB in Ubuntu
