Hello,

LG D802 32GB.

What works:

- factory data reset menu,

- hardware key control mode,

What don't works:

- can't access download mode,

- can't access recovery mode,

- Ubuntu (not vm) don't see me phone, it only see /sda/ but it's my hard disk,

- I'm stuck on "Security error", phone is restarting on LG Logo all the time.

Any ideas? Please help.
[G2 General] Asgarth.bg:
Nope.

Had twrp and custom rom, made a mistake when installing another custom rom, had to go back to stock, but could not enter any recovery, not stock or twrp.

I had flashify for instance, and when I used restart to recovery there it'd just hang after the reboot.
[G2 General] soare95:
now, my lg d802 boot system only LG Logo
[G2 General] Dubster93:
Check the screenshots. See the errors (In spanish says something like "Read-only")

In this, show me the sbl1, recovery, etc.

Then, i use the dd command, and show me this error:

What can i do?

My smartphone is Lenovo Vibe Z, but with the Vibe Z's files.
[G2 General] bender_007:
Try flashing sbl1 first, then flash aboot, boot, laf
[G2 General] Dubster93:
I did it, but show me the same error.

I tried it on my D802 and I push all the partitions successfully but when I reboot my phone it shows the LG logo again and then the black screen appears like in the beginning. Please help me, I want my phone working:(
[G2 General] dkoo:
my phone is stuck on LG logo/carrier and just reboots.

no download mode, no recovery mode.

the phone is detected in windows as 'LGE AndroidNet USB Serial Port' not qhsusb_bulk.

im completely stuck, and i only just got the phone.

please any help appreciated, i've also made a thread.
[G2 General] wajahebat:
Turn Off the phone, Make sure it is turned off completely, in any state your phone is (on), press the power button for at least 15 seconds until the screen completely black and no respond, that is off state. Its hard to turn off D802 when it is stuck like in your situation.

If youre sure it is completely OFF, press and keep holding VolumeUP button while connecting your phone to PC/Laptop. See if there is Download Mode came out. Download LG United Mobile Driver before you proceed with this, if the Download Mode came out, its easy to save your phone actually
[G2 General] dkoo:
Unfortunately I tried this, the phone is off. I then hold VolumeUP and insert USB, but then LG logo comes on and it just goes into charging mode.
[G2 General] bender_007:
How did you get into such issues?
[G2 General] wajahebat:
Thats kinda weird. Charge your phone with wallplug first, let it charge for 1.5 Hours, then turn it off (Press+Hold Power 15sec) then try again to enter Download Mode
[G2 General] dkoo:
My phone was rooted on Cyanogen. I wanted to revert to stock.

I used LGMobile Support Tool with stock ROM. When phone restarted it was stuck on loop.

I went into download mode and in LGMobile Support Tool I click 'Upgrade Recovery', now it is stuck on recovery loop again with 'three' carrier, and I can't get into download mode.

Thanks I'll try this, but phone is at 100% atm.
[G2 General] bender_007:
Try wiping through stock recovery mode (hold volume down and power, wait for lg logo then hold volume up and volume down-without power button)
[G2 General] dkoo:
omfg, i love you!!!

i was ready to throw it out the window, now it's up and running. thank you!!
[G2 General] sergy98:
All done, and now?

I've done all the tutorial carefully and everything went OK, nut when I restart the phone the LG logo appear and it says

"Secure booting error!

Cause: boot certification verify"

I can't run the recovery, the download mode or the fastboot mode. I only can enter to the Hardware key control mode, and it doesn't do anything.

I need help, I've searched for a solution for weeks, and this post is the only that could make the LG logo appears, before there was nothing, only a black screen, the same as the one who appears after the LG logo.

Thank you! :)

PD: I've just found that I can enter to the Factory data reset too by pressing POWER + VOL- until LG logo appeared and, quickly VOL+ + VOL-.

PD2: I tried to reset all data and restore it, but it returns me to the same black screen. Nothing to do in this menu.
[G2 General] Alexander738:
My lg d802 boot system only LG Logo too. it was found that hardware was of D800, but D802 written on the cover. I removed the cover, on the phone it was written that this model D800. I took the stock firmware (LGD800AT-01-V10o-310-410-OCT-19-2013+0.tot) from the D800, dll LGUP_8974.dll and flashed through LGFlash Tool. And the phone worked. Sorry my English.
[G2 General] sergy98:
My salvation!!!!

Thank you very much!!!!!!!!!! I could get into fastboot mode flashing the files for D800!!! Now I'll follow this other guide and that's it!

God will pay you with a great woman!

Also, great tuto and better community!!!!
[G2 General] kryptonite:
Wow , lots of folks who have D802 on the cover but the phone is really a D800 or D801.

Instead, by Windows with Minitool Partition, I see like you see in image.

Have I to do something on Ubuntu or by Minipartition Tool to resume my G2 usable again?

thank you very much!!!

LG G3 Secure Booting Error

Will this guide work on LG G3 D855 as TWRP cannot be installed without Bump, so how to boot into TWRP?:confused:
[G2 General] bender_007:
This guide is mostly on fixing the bricked device. So yes, if you're in that mode OP suggest in 1st post you can dd your partitions in order to fix download mode. If you have download mode = your device isn't bricked.
[G2 General] jrrevoltar:
After doing all this, my phone won't turn on :(

My computer detects it as i hear the USB plug in sound from windows but nothing happens.

My phone screen is just black, no LEDS flashing..

Any help?
[G2 General] xlnzee:
OK, I will install Virtualbox and then Ubuntu on it and try to get at least download mode working, then I can use the TOT or KDZ method. so aboot, boot and laf.img should be enough?
[G2 General] bender_007:
Install vmware instead.
[G2 General] nicklefloss:
so I tried this and now I don't have any touch on screen, for the bottom have of the screen because of twrp, I am also can't type in terminal. what should I do??
[G2 General] xlnzee:
When I give the command "ls /dev/sd*" I only get the below and nothing more. QHSUSB_BULK shows mounted in Ubuntu in vmware.

/dev/sda /dev/sda1 /dev/sda2 /dev/sda5

What else can I try to get all the drives?
[G2 General] bender_007:
Yes, you flashed verizon wireless twrp on d802. Nice.
[G2 General] xlnzee:
So this is what happens. even though ubuntu shows the device is connected, its not showing all the partitions.

Please see the second screenshot where G3 is detected as "QDL mode". any help would be great. thanks!
[G2 General] nicklefloss:
Hey don't be discouraged thats a good thing... Do this on

-boot ubuntu

-get that black screen up

-if ubuntu pops up a bunch of drives... Then take note of the sd* you have. Mines was sdd... The directions said hid was sdb...

-then follow all the instructions on op... Dont restart... Follow the instructions on other thread @ the end of op

And yours should boot... I had an issue with the twrp img my bottom half of the screen didnt work... I wished i continued to the second set of instructions... Goodluck
[G2 General] jrrevoltar:
But Ubuntu doesn't even pick up the device anymore on There. I can hear the sound on Windows. I have tried holding the power down for more then 15-20 seconds but no go.. I completed the steps as mentioned in the op, installed the imgs but after disconnecting and attempted reboot of phone.. Nothing..
[G2 General] rasenshuriken090593:
So, I'm a newbie in these stuffs. They say that lollipop is coming to the G2 next year and I was wondering whether or not this could happen on my device? I got it rooted only to install the camera mod but I didn't install any custom recovery or made any changes besides that. I fear that this will happen and i don't have any experience doing this stuff.
[G2 General] bender_007:
If you had recovery and just take ota it would happen but in a mild way. Easy fixable if you don't panic and flash random.
[G2 General] xlnzee:
Hi Bender, please tell me how I can get the phone partitions detected in ubuntu, its only showing the pc partitions and not of the G3 i have. please help!

Hello, I have a strange problem,my device is still connecting to and disconnecting from the system

Here is my dmesg: http://pastebin.com/LxZB11ut (there are some strange lines with "Buffer I/O error")

DD tells me that "is ok" but, it is not ok even there is no device connected so i think that I cannot write new image with dd because of connecting/disconnecting device.

Does anyone have that kind of problems?

I have bricked my LG G3 and i try to follow this tut for unbrick my phone. I can't acess to download mode or whatever, i just can access to the factory reset mode.

Windows recognize my phone only when i use the combinaison Vol up and connect usb cable. It doesn't show download mode but it is recognized. (in Devices : : qualcomm HS-USB).

I have a pc with Ubuntu.

But in Ubuntu my phone isn't recognized in everything mode i have tested. I don't have any /sdb

I have to plug my phone when is off ? With any combinaison ?

I have try every method.

Someone can help me please ?

Edit: I have installed a VM of Ubuntu and now i have this message error : the connection for the usb device qualcomm qhsusb_bulk was unsuccessful

Any idea ?
[G2 General] Xperia Neo:
when you got that error, unplug your phone and plug it again.

it should connect directly to virtual machine without any error.

but sadly Ubuntu recognize the phone as "Qualcomm, Inc. Gobi Wireless Modem (QDL mode)" and "ls /dev/sd*" command not gonna work :(
[G2 General] toxxiam:

Before you plug it again, did you have power off your g3 ?
[G2 General] Xperia Neo:
yes, i pulled out the battery.

for waking up my phone i have to press vol up and plug it in, then screen will ON and led start blinking, then i will press vol up and plug it again to connect to pc! for waking up it again i have to pull out the battery. is it the same for you?

Got the same problem, stated before.

I understand other people might have difficulties following the tutorial, but there is a few of us that have the exact same issue - done the tutorial correctly, but lost recognition in Ubuntu and now we are stuck in twrp.

Other than download mode what other ways are there to put files on the device?

I believe that ubuntu is not recognizing the phone, because we have "wiped/f**d up our internal storage.

Mine shows as 0 mb. I have tried two different OTG adapters with no luck. (Is there a trick to using an OTG in recovery? I am at older version of twrp as per OP instructions, I think it was 2.6.3.3. or sth.)

Any help if possible?

Thanks!!

After the application "Flashify" I tried to flash the recovery TWRP (version 2.8.0.1), after removing it I flashed the recovery, and I clicked Reboot Now.

After that the device will restart and with the logo Lg there are written:

"Boot certification verity

secure booting error

CAUSES: Boot certification verity. "

In an attempt to restore the original firmware of my Lg G2 I found that my device does not go into Download Mode.

My question:

I have done the tutorial,Ubuntu says everything went well.But when i restart my phone nothing changes?I have done it with 11a,24 and 26a-partitions but i didnt work.A few day ago,my phone went after restart into fastboot mode,in that time i did fastboot-erase,flash I idiot flashed the false partitions,and i think i erased to many files.After that my phone didnt boot into fastboot,only LgLogo.I think everything what i did after that fail was pointless,because somehow it doesnt work.....

It must be said however that the smartphone works, however, does not make me go in download mode.

When I flashed the recovery TWRP and I started the reboot as written previously gave me the error when it became the symbol LG, after a while the screen is turned black and I had to restart the smartphone while pressing volume up, power and volume down for about ten seconds.
