I have a lg g2 d802, i think it is the same phone as in the desciption.

I'm not that familiar with the exact version or number.

where to download the other files for the specific modelnumbers?

maybe flashing of laf.img is needed?

thanks for helping :)

i would definately donate for your hard work.
[G2 General] kiapsita:
I suggest you to think about it.

I followed that procedure, I substituted those files and, in result, I obtained access to TWRP recovery but everything is wrong and don't work.

When it was black at least it was seen by pc (qhusb_bulk)

Actually, I regret I did this. Cause I could've send to LG assistence and they cannot know that it was my modding-fault, so they should have repaired for free.

But now, if you do that procedure with no OTA, you risk to stuck in a permanent useless recovery that;

- doesn't support USB OTG

- doesn't work on ADB Sideload

- can't install .zip new recovery that you could ADB Push inside the memory

My advice: don't run.

G2 keeps connecting and disconnecting

Hi all!!

I spent 1 week trying to save my G2 (Korean model F-320K), but no luck.

I think I can´t flash the partitions, as described in first post here, because my G2 keeps connecting and disconnecting in Ubuntu (the phone screen flashes too).

I can see the phone partitions in Ubuntu one time, after that I cannot, 10 or 15 times, after that can one more time, after that cannot for 15 times...... I have to apply the commands several times to "capture" the exact moment that the phone is connected.

When I catch that moment, the phone partitions shows normally. But If I try the command 1 second after, Ubuntu says the phone is not connected.... totaly crazy!

I tried to flash every partition several times (maybe 100+ times), hoping to capture the ***exact*** moment that the phone is connected (maybe miliseconds).

But... no luck... only screen flashing and phone connecting and disconnecting.

In windows, I can see the phone as QUSB_BULK etc

Any ideas to "stabilize" the connection in Ububtu to flash properly???

Thanks!!
[G2 General] kiapsita:
I had the same problem. But you can use adb push instead of adb sideload.

First, you have to install ADB Universal Driver, connect your device in recovery mode and let ADB Universal Driver find your device -it will probably ask you to install required drivers. Press 'ok' and wait till finished. Once ADB Universal Driver says it can recognize your device (plugged to PC in recovery mode), just do these steps:

1. download twrp 2.8.1.1

2. download SDK manager, then extract "sdk folder" and "SDK Manager.exe" in a new folder in your HDD, I did this -> C:/Android/

3. copy TWRP 2.8.1.1's ZIP in C:/Android/sdk/platform-tools

4. right click + shift on "platform-tools" folder -> "Open command prompt"

5. plug your device in recovery mode (make sure ADB Universal Driver, as I said before, had install the drivers and says it recognizes your device)

6. if you opened the CMD prompt correctly, you should be in this folder:

If you're not, just type:

Then:

It will say "daemon restarted succesfully" after a little bit, then says device is connected as USB

Type:

adb devices

Make sure your device is listed as "recovery" next to a series of numbers and letters. If it is, you can push files inside -just SMALL files!

My TWRP 2.8.1.1 was smaller than 10 MB, and that's okay.

So now let's say that the TWRP ZIP file I wrote to copy in "platform-tools" folder is named "twrp.zip". You need to type:

Press "Enter". Wait some seconds.

If it says something like:

<7929 kb to 7929 kbs> or similar, it means the file as been copied in your memory

7. Go in your device -> recovery. Not reboot, or you'll need to push the zip inside again. From the options, as I said before ("settings", i'm not sure, don't remember very well) flag "Use rm -rf instead of formatting".

Then go to Mount -> select System + Cache

Then go Install-> sdcard

here, select twrp.zip

swipe and let it install! ;)

Hi guys, i've got a BIG problem, two problems really :

1) By using VMware Player : When I try to do "sudo -i" and type the password ==> OK but ... for the 3 others commands, my cell phone disconnect and re-connect continously, that could not permit the replacement of the files...

2 ) By using VirtualBox : When I try to do "sudo -i" and type the password ==> OK but ... The machine only detect "sda", "sda 1", "sda 2", and "sda 5", with cell phone connected to the machine...

Help please, I don't have to much time to repear it ... :(

Installing Ubuntu on HDD beside win 8.1 helped me that the phone was recognized permanently in ubuntu

but also ive followed all the steps i still got no working device

i ve sent it to service center today
[G2 General] jgpi32:
Oh... thanks man, but .. that's strange... I'm like "danielsigma", and I hope my phone is not fully bricked :eek:

Maybe i'll do as you says, but if someone else got an issue...
[G2 General] danielsigma:
Maybe installing Ubuntu in HDD??

Yeah, I tried/status:

- Run Ubuntu from Pendrive: phone connecting/disconnecting, recognized sometimes under "SDC", but no luck in several flashes (I repeated every comand 100+ times trying to "force" to flash and nothing!!)

- Run Ubuntu in Oracle Virtual Box: phone not detected (only SDA 1 ~ 5).

I will try run Ubuntu in VMWare and/or install Ubuntu in HDD to see if this helps "stabilize" connection.

I feel that we have to first fix the connection between phone-pc to flash all the commands properly, otherwise this will not work.

Any ideas apreciated! thnx
[G2 General] jgpi32:
I'm with you ! Fix connection is the priority I think .. I've got same results ... I'm following my researchs on the web and on the differents Virtual Machines. If you install Ubuntu, please tell me the progress you see !

Need Help

Hello Guys,

I am from Germany, so don´t mind my English. I bought a G2 801BK in ebay. After unrooting and installing a twrp recovery, the phone made ota-update. I was stucked in the Recovery Mode.

Then after hours of searching in internet i managed to get out of this loop. First i flashed obviously a wrong firmware, so the touchscreen reacted not in the way, it ment to be. I flashed again with flashtool 2014. Then the phone restarted but the flashtool stopped at 90%. I think I am bricked now, cause I cannot get in the download mod (it starts only till the little blue dots, but no recognation in the pc) and when i start it stops at the lg-logo and the led is blinking blue and green. the phone will be recognized as modem and LGE AndroidNet USB Serial Port.

I was able to bring the phone in the Qualcomm HS-USB Diagnostics 9006 Mode and could recognize it with ubuntu (in VM). It recognizes all like in your description, i can make the dd´s, but when i reboot the g2, nothing happens again, its like before. Maybe it´s not writing in the .img-files? But i got no error message. What I´m doing wrong? Maybe you can give me the hint to unbrick it.

Now when I´m in ubuntu the phone gets recognized and it seems to be sdf, but the .img files i need to change are written in white and not in yellow. What is this ment to be now? Please help. Greets

Hello,

I am trying to restore a bricked LS980 that shows as QHSUSB_BULK in Windows, but I cannot get Linux to detect the phone. I have sda and sdb to view with gdisk, but sda is my hard drive and sdb is the USB stick that I am booting ubuntu from. I cannot see the phone partitions. Can anyone help me get past this to be able to flash the files? Thanks!
[G2 General] Begolin:
Hi, I was using this Thread (http://xdaforums.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404), it sounds difficult but its not so. But you need a little bit of patience till it works. The phone will be detected in 9006 diagnostic mode, this is what worked for me. Then it was detected in my ubuntu, but I cannot boot already. Maybe it will work for you. Greets

Hey guys. After this step: "ls /dev/sd*" it only shows about 7 entries up to SDC1.

If i try to go further to this step "gdisk -l /dev/SDC1" it doesnt display any files like in the example. Could this mean that my G2 is just wiped clean with no files in it? Could this be connected that windows tells me when i connect my lg g2 that i have to format it?..

I could really use your help. Dunno where to go from this

Do you have any tips on getting it into the QDLOADER 9008 mode? When I probe the capacitors my QHSUSB_BULK dissappears from the Windows device manager, but then when I release the probes, it returns. I never see anything about the QDLOADER mode.

LG G2 D800 is only been detected as Unknown Device in device manager

Hello, for the past week i been without a phone since for some reason stopped working, i was using iMuscle when all the sudden the screen went black, after trying to boot it back up was stuck on LG logo, i left the phone there since i didnt had the patience to dial with it at that time the phone was rooted with TWRP and Rom CloudyG3 v2.0, after that in the morning i tried to turn on my phone and was only going to download mode and nothing else so i went ahead and flash the .tot file to leave it as factory reset this was completed successfully i rooted and after i tried to install TWRP went to back to a black screen, i flash it once again with .tot file and was completed once again and all good but this time i tried to root and went directly to black screen, after this my devices is no longer going to download mode and the computer at this time only detects the phone as unknown device on device manager, can someone help me since i been reading a lot of information but nothing regards this, hope someone can help me out.
[G2 General] Begolin:
First of all, I hope for you, that you disconnect the battery from the mainboard, when you try this, cause otherwise you can destroy all. Then when you bridge the capacitors you need alot

of patience. Have an eye on the screwholes in the top left and right corner. Because when you are doing right, getting it in the right moment, then there will be something turning on (I think its the backlight from the LCD). Sometimes i needed to try it more than 20 times. When the light turns on, in my situation a lot of windows started flashing for to format hdd´s. do not just close. Then you are in the diagnostic mode and ubuntu is recognizing the g2 in the right mode, where you can use thread. I hope I could help you.
[G2 General] boostedcx:
Do I have to simply touch the capacitors once to get it into the QDLOADER mode, or do I have to hold the bridge on the capacitors on the board for the entire time I am performing the flash in Ubuntu? I am able to get QHSUSB_BULK to disappear and reappear in the device manager, but nothing else comes up. Under which category would I expect to see the QDLOADER in my device manager?
[G2 General] Begolin:
Hi, you need to touch it just one time, till the backlights from the lcd turning on. You need to try it a couple of times, till its working. It will be aappear in serial ports, in my situation it was called

Qualcomm HS-USB Diagnostics 9006. With just Qualcomm HS-USB QDloader 9008 it was not working in ubuntu.
[G2 General] boostedcx:
I have been trying to get this device into QDloader mode for 3 days with no luck. I just installed Ubuntu on my local hard drive to try to help the connectivity problems but the phone is still not detected in Ubuntu. It is QHSUSB_BULK in Windows. What physical metal tool are you using to short the capacitors? I am using a speaker wire. Thank you.
[G2 General] Begolin:
Speaker wire should be okay. I was using just a normal copper wire. maybe this method is not working for all, for me it was.

I was able to get my device into Qualcomm HS-USB QDLoader 9008 (COM10) mode by installing a driver to the QHSUSB_BULK in my Windows device manager. However, this did not change anything - the device is still not found in Ubuntu. Any tips?
[G2 General] Guereman:

[G2 General] danielsigma:
Only connect - disconnect

Hi, thank you!

But no luck here.

When I run gdisk -l /dev/sdc (my G2 is dettected under sdc), sometimes I get this

Problem opening /dev/sdc for reading. Error is 2

The specified file does not exist!

And sometimes (maybe 1 time each 15 commands) I get the list of phone partitions.

Phone keeps connecting and disconnecting, screen flashing, and the communication between phone and PC is erratic, and I think I flash is not working beacuse this....

sooooo frustrating... Any ideas to get the phone permanently recognized in Linux?

Thnx a lot
[G2 General] Gabriel51:
Sadly it looks like JTAG time:crying:

I bought one with the same problem, if it shows the logo with none of the fastboot writing on the upper left corner or it says something like "security boot failed" it's hard bricked.

So I bought a G2 with a damaged screen so I can rob the logic board out of it. (it's not here yet)

Also:

MobileTechVideos could not fix this problem, they wanted to sell me a new chip? They said they have the JTAG equipment but I doubt they do because they could just rewrite the boot sector, seems to me?:confused:

Look around and find another board for it or find a real JTAG service and post your results here...

Good luck...

Ubuntu problems.. help please..

Hi guys, I've installed ubuntu 14.04 and them, my Lg G2 is not detected by the OS, when I type " ls /dev/sd*" after my LG connected, I only can see "dev/sda", "dev/sda", "dev/sda1", "dev/sda3"....

Could somebody helps me to find a solution to see the others sd* and to continue the unbrick please..
[G2 General] Gabriel51:
If you see the same thing("dev/sda", "dev/sda", "dev/sda1", "dev/sda3") with your device unplugged then Ubuntu is not seeing your device...
[G2 General] jgpi32:
Yes i think so.... Any idea to fix this ?
[G2 General] danielsigma:
Guys, another question

Is there any difference between flash .img files and/or .bin files??

.bin need to be converted to .img? Simply renamed?

I'm confused on this...

Thnx a lot
[G2 General] Gabriel51:
If your computer can not "see" your device then you cannot do anything to it.

Look back through this thread to discover different methods to get your device discovered.

If all of those methods fail then your device is hard bricked and JTAG is your only hope...
[G2 General] danielsigma:
Yeah!!

After 15 days, finnaly, I got it!!

G2 back to life!!

Thanks A LOT and all the credits to the user popaclaudiualin!!!

To the guys that, like me, are having connection issues on Ubuntu (phone restarting or dont recognized), here is the trick:

DON'T USE UBUNTU!

I used Linux "knoppix" (Google for it), running from a pendrive, and voila!

G2 recognized without problems and flashed like a charm. Download mode again!

Thnx a lot to all :)
[G2 General] 6ril1:
With dd cmd you can simply rename, ext is not important.
[G2 General] supar2000:
what is your symptoms?? Does it like only LG Logo on boot, no recovery, no fastboot, no download mode ??
[G2 General] danielsigma:
Hi, all of them.

Phone was looping on LG logo, no recovery, no download and no fastboot.

Tried the tutorial on 1st post, using Ubuntu, flashed all commands several times with no success.

Phone was not 100% recognized in Ubuntu, the screen was flashing and G2 kept connecting and disconnecting all the time. I was capable to see it sometimes (the partitions), but Ubuntu, in my case, was not capable to flash the phone.

Tried a lot of times running Ubuntu in pendrive, CD and HDD and nothing.

Then I changed Linux OS to knoppix distribution. Followed the tutorial again and G2 was recognized with no problems and was successfuly flashed.

It made a difference. Knoppix worked 100%

My advice is to try flash the G2 in Knoppix, not Ubuntu.

I ran the knoppix in a pendrive, no need to install.

Thnx and good luck
[G2 General] Gabriel51:
Where do you find the "terminal" in knoppix?:confused:

Well I've gone ended up buggering up my beloved G2 I've followed this perfectly and pushed all the files but I'm still at the same point where the back light is on with a black image and this is all I'm getting and nothing more anyone give me any direction what I can try? whilst I spend a few moments having a cuppa' and calming down a little :(
[G2 General] Gabriel51:
slax works a lot better than ubuntu.

However this did not solve the problem. I had to find the right combination to find the files and you can see where I was trying different inputs to get it to take it, and I did find it but I noticed the recovery file was for an 802 and I have an d800.

I wonder are any of the other downloaded files strictly for a 802?

Or is it that I loaded an D802 recovery on my d800?

Pictures are crappy because they were so small in Slax, I may start over shortly with the correct recovery.

Also it's not easy to get my phone recognized, I have to keep trying to boot it because It was only when I saw the logo briefly that I was able to connect to it...

At least it saw it once!
