[G2 General] yahooking:
I had the same exact issue as above. The phone disconnected itself after I pushed sb1. And then I lost it forever. So be careful ONLY push it if the device remains connected in /dev. In my case after I pushed sb1. The device disconnected itself and it is now fully bricked. My only hope is JTAG when and if it eve gets JTAG capabilities. So be careful !
[G2 General] Partager.info:
First of all be sure that you've downloaded the good files for your variant.

Then execute all commands at the same time to push all files in a minimum time, just copy all commands, paste them in terminal then execute them once. This way you will not lose time to copy each command and past it while your phone is disconnecting.

Give it a try.

Good luck.

Mo USB connection with PC in download mode

Hi guys,

could i ask you for some details about LG G2 D802 partitions?

Can you tell me purpose/description of sbl1, aboot, rpm, tz partitions at least please? (I will be glad for description of others too...)

I am trying to understand what i am doing with my LG G2 and how to fix it...

I have currently problem with my LG G2 D802 32GB.

Description:

- Android CM11 works (installed via TWRP)

- TWRP 2.6.3.3 works

But now i am trying to flash stock firmware via downlaod mode (volume up then plug in usb cable, then i got black screen with little rectangle with blue dots) + offline Windows method but when i am in downlaod mode my pc don't recognize USB device (no usb sound in Windows). Something is wrong. I tried to install USB drivers from tutorials to my PC (Win 8.1 64b or Win 7 64b), but no change. :(

Could you advise me please? :crying:

Thank you in advance... I'm desperate
[G2 General] fucon:
Thanks a lot for the solution!

I followed the steps, except that I did not diable the automount.

After dd all the files, I unpluged my phone (without unmount) and try to reboot but it would not even power on.

Tried to plug in again and do it all over. but the ls /dev/sd* only shows a few sdk (* is k in my case) partition, (5,8,6,15) basically just the ones we made change to, exept that there is no 2! Is this normal?

So I was unable to do the dd command to 2 as it does not exist anymore.

Could any one help? My phone is a total brick now and it will not do anything no matter what button I press. no lights on charger either.

Thanks in advance!
[G2 General] Sneaky Elephant:
Stuck on command ls /dev/sd*

Input command ls /dev/sd* which returns /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 none of which are my D800. Attempted to install qualcomm drivers, but device manager says that the drivers match but don't pass the hash check and will not assign drivers to the device. This is a great write up, my phone just isn't cooperating. Please help!

Also, the files noted by the OP:

1- sbl1.img

2- aboot.img

3- rpm.img

4- tz.img

Are these safe to use for my D800 or will i have to find them for my variant?

Thanks all!

It said the first readable sector is 34 Does it mean everything above is corrupted. As directed have replaced the sbl1, aboot, rpm, tz, laf and twrp recovery files. What else can I try? If I can get the first 33 files/images I can replace them in Ubuntu! Thanks.

Update: Fixed. Can't imagine its that simple! I was doing OTA from 10o to 10q when it bricked with symptoms described in this thread. I followed the instructions but still nothing. I also tried TWRP 2.6.3.3 and resulted with boot error. Then I tried the STOCK recovery and rebooted. Phone booted and started to upgrade to 10q which was downloaded before. Hope this helps.

Touch Calibration Issue ! :(

Hello all

I seriously need help from anyone who really can support !

I followed this guide http://xdaforums.com/showthread.php?t=2667714 to flash rooted kitkat on my G2-D802

the phone booted and when I started using it...it was really useless ! The screen's touch is crazily miscalibrated :(

I have no custom recovery now and I am unable to install it and I don't know why :(

I can boot into download mode and I have even struggled to enable USB debugging and finally could do it!

I downloaded jellybean kdz in order to flash it but it failed to flash using the flash tool

After that I took it to LG and they returned it as refused :S because it appeared rooted in the download mode

Now that my phone returned from LG, I feel hopeless :( I tried to connect my phone to Ubuntu

the command ls /dev/sda* gave sda1 sda2 sda3 so it seems like the phone is not recognized or what ?

Please provide me with solutions and I am glad to donate :)

[G2 General] andriodee:
Do you think this method will work for me? Here's my issue:

So, a few days ago, I was running CM11 for the Sprint LG 2 (LS980) and decided I wanted to revert back to stock and OTA to KitKat now that it became available to us Sprint users. I used the dll and tot files and LG Flashtool'd back to stock 4.2.2 ZV7, then took the OTAs until I got to KitKat. After I was stock and rooted, I did some browsing on here and came across a forum that had a temporary fix for those who wanted TWRP. You had to downgrade your aboot (which would, of course, break download mode) by flashing it through the terminal on Android. Then you had to install TWRP and install this zip that made ZVC bootable with the downgraded aboot. He also gave us a zip file that we were to use in case we ever needed to get download mode working. Anyway -- I downloaded all the necessary files and proceeded to downgrade my boot. After I downgraded, however, someone on here talked me into not bothering with going through all that, and told me I should just wait until a simpler less problematic solution was available to us. After a while of going back and forth, I decided he was right, all the while forgetting I downgraded my aboot. So, I edited the IME lines in the Build Prompt to enable Trace Input on the stock LG keyboard and proceeded to reboot for the changes to take effect when it hit me: I HAD ALREADY DOWNGRADED MY BOOT AND DIDN'T FLASH THE REQUIRED FILES TO MAKE IT BOOTABLE WITH KITKAT, NOR DID I HAVE A RECOVERY TO BOOT INTO. Now, when I turn the phone on, the LG logo appears and just stays there. When I try to boot into recovery mode, it says "Recovery Mode loading..." and stays there. When I boot into download mode, it just hangs there, as well. My computer recognizes my phone, but as a High Definition audio driver instead of COM device in the Device Manager, so I can't tot back to KitKat fresh.

And to make matters worse, my G2 was also my internet connection, as I was tethering my LTE since I have no wifi here at home (?). Now I just don't know what to do. I managed to use my mom's phone to download the files mentioned on here to use with my Lubuntu terminal, but the gdisk command has to be installed with internet! Coincidentally, her Verizon data plan has reached its limit, so I can't use PDANet with her phone. The iPhone 4 I have as a temporary phone until I fix my G2 or get a new one especially can't tether nor download any files onto it, so I'm just completely screwed.

What I'm going to do, though, is go to the library tomorrow and try to do the "sudo apt-get update" or "install" command to get gdisk so I can try this method. I just wanted to know if you knew if it would work or just make matters worse.

P.S. Sorry for the shipload of text to read through. Just wanted to tell you how I messed up so I can tell you if this works (IF I get a chance to).

Stucked at lg logo

after 4 hours, i finally managed to do what was written. i followed everything but now my phone stucked at LG screen. any ideas? please help.
[G2 General] andriodee:
So, if I don't have a ROM to flash, I'm basically still screwed? Is there no way to just get download mode working again so I can just flash the ZVC (KitKat) .tot file? Or do I have to have a ROM to flash in recovery? Also, I have a backup of my stock LS980 ROM, but it's a PhilZ Custom CWM backup. Is that TWRP compatible?

No sdb?

When I type the ls command, it only returns /dev/sda1,2, and 5. I'm running ubuntu on a Virtual Machine and my phone is plugged in. What do I do!?
[G2 General] andriodee:
No one is responding to me and I really need some help! I'm running the latest (stable version) of Lubuntu and I'm able to use the terminal, but when I plug my phone in and run the ls /dev/sd* command from the terminal, only /dev/sda, sda1, sda2, sda5, sda6, and sda7 pop up. I've listed those disks, and the first 3 are Linux-related, and the last 3 present me with this:

"Partition table scan:

MBR: not present

BSD: not present

APM: not present

GPT: not present

Creating new GPT entries.

Disk /dev/sda7: 16181248 sectors, 7.7 GiB

Logical sector size: 512 bytes

Disk identifier (GUID): 961F0DED-EFE6-4DC0-91CA-8C73FC0F1A87

Partition table holds up to 128 entries

First usable sector is 34, last usable sector is 16181214

Partitions will be aligned on 2048-sector boundaries

Total free space is 16181181 sectors (7.7 GiB)

Number Start (sector) End (sector) Size Code Name"

It's blank underneath each set. No list like the table the OP presented. I have an LG G2 LS980 that has no download mode, no recovery, stuck at the LG Logo, and isn't recognized properly by the Device Manager in Windows. Will someone PLEASE help me!?

I'm having a similar issue. No one is responding to me. Either they're arrogant or they simply don't know how to help us. Which LG model do you have? I have an LS980.

I have that same variant of the G2 and I also downgraded my aboot, but I forgot to flash the recovery after I did it, so my phone is stuck at the LG boot logo with no recovery and a broken download mode. You think you can help me? The Device Manager in Windows recognizes my device as a HD Audio Bus (whatever that means), and when using the terminal on Linux, it doesn't show at all.

Please help! I followed the tutorial to the T and was able to push all noted files to my D800, but my phone will not boot into recovery. It starts up, lg logo appears, then goes to gray screen with only backlight on. I have no idea how to get it into twrp now
[G2 General] secret.animal:
I'm not sure if the button combination is different between models.

But if you still have a recovery TWRP, then you may be able to side load the zvc radio to get download mode back.

Button combination for recovery is usually power phone off completely. Means good power until screen shuts off. Lg comes back up and then disappears all while power is held.

Then volume down with power.

If that doesn't work try. Volume up with power.
