[Q] LG d802 recovery hell - G2 Q&A, Help & Troubleshooting

Hi All,
I hoping some kind soul will guide/lend a helping hand here?
Here's my problem, I own an LG G2 d802, running kk4.2.2, rooted via towelroot.
Today I decided to for the first time to delve into the world of custom ROM's and what a mistake it was
Basically I downloaded TWRP for d802(img), gapps(d802 version), and cm Resurrection Remix and then I made the fatal mistake of using Flashify to flash TWRP to my phone and rebooting. After doing this I can no longer enter download mode, recovery mode, and when I try to go to either I get the ERROR: boot certification verify: secure booting error.
When I i plug my phone into my computer (drivers & LG support tool installed) my computer recognizes my device, however it displays around 10 or so removable drives i.e f, g, r etc and lots of messages appear saying i need to format them before they can be used and Support tool doesn't recognize my phone as being connected at all
I have searched lots of threads and now realize that Instead of using Flashify I should have used Autorec(lesson learned), I have also searched for possible solutions and the only
one which looks remotely viable is here:
http://forum.xda-developers.com/showthread.php?t=2582142
My only problem is I have LG G2 d802 32gb model and the files in the above guide/solution are for the LG G2 d802 16gb 10a and even then if they was the correct files I think i would still have a very hard time following/using the files to make my phone live again and also have no knowledge/exp with Linux distro's.
I am a total noob/idiot and don't have a clue how I am going to fix my phone and have pretty much pulled out whats left of my hair in despair!!
Please help me.
Kindest regards, Dark.

I am literally going insane now is there no one here that can even be so kind to say if the above is even the correct way for me to go? or point out a way which may be better or a step by step/link to things I need?
I really don't have the exp/confidence or knowledge to be bale to know if its correct or not and really don't want to make things worse by trying something that may not be right
Can find threads and websites which have similar type situation but all seem to have slightly different to my own as most can seem to have download mode or still be able to boot their OS but i cant do either.
is this below method any use for my situation?

You say in your original post you're running KK 4.2.2. 4.2.2 is Jellybean not KitKat, so which one are you running exactly?
If you didn't use AutoRec your bootloader should still be a Kitkat Bootloader since AutoRec's job is to downgrade your Bootloader to Jellybean.
There are 2 ways to access Recovery Mode on a G2 depending on the current Bootloader.
Method 1 (Jellybean Bootloader)
Turn G2 Off. Hold PWR + VOL DWN, when LG Logo appears let go and hold PWR + VOL DWN.
Method 2 (KitKat Bootloader)
Turn G2 Off. How PWR + VOL DWN, when LG Logo appears, let go and hold VOL UP + VOL DWN.
Do either of those work?

Well since you can't access Recovery Mode, you can't access Download Mode and your receiving a Boot Error, It sounds like your only option here is to follow this tutorial.
As for the files you need, you have a 32GB D802. Download this .7z package and extract it. You'll find all the .img files you need. Now follow the tutorial .

No worries hope everything goes well If you're unsure if any commands just send me a message or post here.
Note: It's nice to hit the "thanks" button under my posts if you are thankful Saying thanks without clicking the thanks button is like a slap in the face .

Quick update just before i commenced with the tutorial , i once again tried the key sequence for Download mode and recovery mode and to my surprise got a different result to yesterday!
I now can do factory reset which wouldn't let me do yesterday , have started it but now worried as its been the little green android man with blue spinning cogs in his chest for about for 15 minutes now and fear i may have made things worse

HEY! I'm on the d801 as well and I've been where you're at a number of times, unfortunately. But I've always gotten out. Here's the conclusion I've reached. Trying to flash directly back to stock without wiping all the partitions first is what makes the RDTool get stuck. It's like the phone runs out of memory and can't host a full Gig+ of data since your last ROM is in the way. Sorry if I'm wrong but I'm only assuming you didn't wipe everything except the Internal storage. The good thing every time this has happened to me is that your recovery partition should be intact. Mine always is, and we're on the same variant. Another thing, booting back into recovery is not impossible. It's all in the timing it takes from the first time you see the LG logo while holding volume - and the power button, but don't let go. What worked for me was to let the phone cycle between off and boot power states twice until the phone is completely off again. You may even notice the LED indicator flash red. Release your keys if the phone stays off and immediately hold the combo down again until the phone tries to boot again just don't let go of the buttons. Once it powers down again, leave the phone alone for a few minutes. Come back and this time get ready to boot into recovery. The combo button press will initiate boot but don't let go until the next time you see the LG logo flash, then quickly release and depress the vol down power up combo and hold. May take a minute longer than usual but the reset menu should pop up thereafter. Tap power 2 more times and you should back into recovery. It's worked every time for me. Let me know if you're good and whether this helped!
Good Luck,

OK. So tell me, what ROM were you on, which recovery version and name are you using, why were you flashing back to stock, i.e. were you having problems, what kind. Explain as much as you can in detail. Need to retrace your exact steps to best get you fixed up!

K, now if you're only seeing the blue dots when you attach by USB your phone to PC, then you're not fully in DL mode to process the kdz. You should see a white wheel in the center of the screen when you connect and a viewing mirror near the base of your phone with ROOTED in red directly below that. And you're sure your PC is detecting your phone? You've the drivers installed? Because when RDT tells you to run the tool, you'll see some binary code in the viewing window I spoke of, the white wheel will turn and below it will be shown the COM port to which you're connected and a solid thin red bar will begin to fill a space in the viewer showing you the progress.
Also, be sure when attempting the first steps I gave you to boot into recovery that you are not USB connected. It won't work.
And, try to remember if your phone was well enough charged, should have been at least 80% full. It happened to me once that I couldn't boot recovery and my phone would go to fastboot like yours until I left it alone to charge and then I repeated the stepsvi laid out to get back into recovery. This part is paramount!
Please READ CAREFULLY
I used to be in your same situation. I thought I had bricked my phone for good. I finally figured it out. Here is my solution from my Thread.
Esteef said:
Okay, after 12+ hours of trying every method possible on XDA I finally resolved my issue. I will update the first post just incase any others care or fall into the same dilemma I was in.
The LG Mobile Support tool would not download the firmware and it would NOT ask me for my IMEI to download it either.
So my solution....
***
Installed LG Mobile Support Tool then Installed the LG Drivers. (FROM HERE http://forum.xda-developers.com/showthread.php?t=2471370
BEFORE I connected the phone to the computer. I opened the LG Mobile support tool clicked (Options on the top right).
When the dropped down opened, I clicked the (Upgrade Recovery) option. THEN, is when the prompt opened to ask me what my IMEI is.
Before I entered my IMEI, I connected my phone to the computer in download mode, then proceeded to enter my IMEI and hit OK.
This is when the LG Mobile Support tool SUCCESSFULLY downloaded the latest official LG firmware and installed it.
*** BE AWARE, with the phone connected to the PC, the prompt NEVER appeared to enter my IMEI.
*** But with the phone disconnected, the prompt came up every time. This might be the trick for some people.
*** with the IMEI prompt opened, I then connected the phone , entered the IMEI, then hit OK. BOOM HERPES....
Well I'll polish this up more later. I hope this works for every LG G2 Variant and not just the T-Mobile one (D801)

Sounds good. A full charge can make all the difference. I learnt the hard way! One or more of us will be along should you need further help.
I do hope you get this sorted! I've come back from the brink too many times to not believe you won't.

[Q] Hard bricked G2 after flash

Hi everyone
I may have bricked my G2. I use to have a Samsung Galaxy S which I flashed many times so I kinda know when I mess up with instructions. This time though, things look a bit more serious... Anyway, here is what happened:
I flashed the Cloudy G3 rom (1.0) for my G2 D802 32gb. Original rom was stock rooted 4.4.
I followed the instructions :
- Backup rom
- All wipes
- Flash kitkat baseband
- Flash rom zip
- Get through the aroma installer steps
But then, when it asked to reboot, the phone just shut down.
Now it won't turn on. All I have is a quick look at the LG boot logo, and then the screen goes all black (blacklit is still on) again.
All I managed to do so far is maintaining the LG boot logo a bit longer on screen by alternatively pressing volume + or - at random times.
I can't access recovery or download mode anymore.
Plugging the phone will only show the LG boot logo and do all the same.
The phone is no longer recognized by my computer.
When I plug it, I get 13 new windows asking me to format the device and one I can explore.
Inside, there is one folder named "Image", filled with 51,4 Mb of files...
Quite confusing.
I don't know what to do, so any help to get the phone back to work will be appreciated
Thank you in advance.

At least I'm not alone :laugh:
I found this thread but haven't tried yet. Don't know if the problem is similar.
I really hope the phone isn't dead, it's almost brand new
This is exactly what I have . The main problem is we can not see phone partitions. Always the alarm "can not access " or "format" !Waiting for some body to help restaure our LG G2.

Are you still under warranty. If you can't get into download mode that means that LG won't be able to either. You could process a return directly from LG.
Problem solved ...
Somehow I did manage to hard reset (vol - & power, wait for LG logo, release and then press vol - & power again) and then access recovery mode, so I did restore my backup (which had been renamed to ... 1970-05-01 ! lol) and my G2 is now back to life.
Weirdest thing ever... Kinda worried about flashing it again now !
Thing to remember : always have a backup file.
You are lucky man! I've done it but nothing after. I can access to hard reset but when I push power button the screen goes black as before ....
Is it actually in "Download Mode"?

So, if my G2 shows "Download Mode" on the screen with the little white dots, but it's not recognized by Windows 7, Ubuntu, or Knoppix, and is for all intents and purposes, non-responsive, does anyone know if it's actually in "Download Mode"?

[Q] Flashed wrong kernel!!!

i Was trying to get rid of the hissing noise on my
Lg g2 D802
i had TWRP installed
I read in a trhead that flashing the dorimanx kernel should fix that problem.
So i tried flash it, but instead of flashing the D802 i flashed the D800, i know i'm an idiot :/
I had a backup stock kernel but i think that's a wrong one too, again i'm an idiot
Now my phone boots into a black screen within the left top corner:
[2800] Fastboot mode started
[2850] udc_start()
i cannot boot into twrp anymore, it's basically bricked.
Can anyone help me recover my phone? i loved that thing, you will be my hero.
i promise when this is resolved i will never mess around with roms and kernels ever agian, i'm freaking out

So i tried flash it, but instead of flashing the D802 i flashed the D800, i know i'm an idiot :/
I had a backup stock kernel but i think that's a wrong one too, again i'm an idiot
Now my phone boots into a black screen within the left top corner:
[2800] Fastboot mode started
[2850] udc_start()
i cannot boot into twrp anymore, it's basically bricked.
Can anyone help me recover my phone? i loved that thing, you will be my hero.
i promise when this is resolved i will never mess around with roms and kernels ever agian, i'm freaking out

Try to flash back to stock with kdz, as far as I am hearing this you kinda soft bricked it but not hard so it's still recoverable, you could also maybe try to flash your recovery back with fastboot since your in fastboot mode but I never tried that so I suggest you to go back to stock with kdz flashing
ye try enter download mode and follow this (use search) i think its volum up and connect usb to pc

Thank you for your reply, i tried to get into download mode, but failed every time, i can only press the power button for 5 sec and the Lg logo apears, then i get the same screen.
did this way?
Your phone must be turned off before starting the steps from this guide.
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
Now the phone will install some drivers – it should take around 10 minutes to complete; the best will be to let your device install the mentioned drivers.

I did the same thing today by accident. I still can boot into recovery tho, TWRP. Copied the correct kernel file via OTG but it just reboots the recovery and doesn't install the kernel. Have you find any solutions?
EDIT: I actually managed to flash the right kernel and the problem is now fixed. Check everything before flashing something guys, caution

[Q] Half-Bricked G2

Hey Guys!
As I finally gave up looking through hundreds of comments and several different threads I will try it this way...
I am not new into flashing, as I messed around a lot with my Galaxy S2 and especially with my HTC HD2 (loved that thing!)
Now I wanted to flash my G2 too (after 2 years with stock rom), but something went wrong. I can neither enter download- nor recoverymode. But it works as usual, even after resetting it to factory state.
It just showed me the boot security error then I was able to force restart it by holding Power + VolUP and it was reset to the state where I bought it.
I rooted with ioroot, then I tried to put CWM on it (CWM-Official- TOUCH-6.0.4.4(D802)), which I already figured out that it wasn't the best idea, since everybody seems to use TWRP on his G2. But I didn't know a thing about TWRP and I was used to use CWM for flashing, so I tried it.
Then I read that there is a problem with stock ROMS and ADB root, because the CMD showed me an error saying that "adb cannot run as root in production builds". By doing some research on the Internet I figured out that something went incredibly wrong. ( I also forgot about the bootloader.. it was a long time since I flashed a phone )
My Phone is a open LG G2 D802, KOT49I.D80220g, 32 GB.
I have already messed around with this for some time, but it wasn't successful since the device wasn't shown in the ls command, I assume it's because it's still recognized by Ubuntu as an MTP? (I read to page
http://forum.xda-developers.com/showthread.php?t=2582142
But every other solution I have found requires download mode, which I'm not able to enter (Not by pressing Power + VolUP (or Vol down) until LG Logo, then release and press again, nor by holding volUP while plugging in the USB cable (of course the device was powered off))
Does anybody have some advices?
I hope I gave all information you need.
Kind Regards
Lukas
Is your device rooted?
Yes it is.
I think you might have to short the chip to force it in qhsusb mode and flash laf.img,aboot.img and boot.img

LG G2 Might be bricked, not sure.

Hello, cutting to the chase
Model: LG G2 D802
Story time: I tried to install ressurection remix rom through the sideload, after fully wiping my phone ( Wiped system, data, yada yada ) it showed some kind of an error about SU not installing properly, I thought well if I'll reboot TWRP will automaticly install SU for me, so when I tried to reboot it showed that No OS is installed, I thought it's a simple bug so I'll reboot to recovery again to check and bam. Nothing works.
+ Can't boot into recovery ( Tried volume down + power button ) LG Logo shows up and goes blank again ( Note that the screen doesn't turn off, just stays black, after holding it for a couple of seconds I can see screen going off completely but can't turn it on)
+ Can't turn it on normally.
+ Can't boot into download mode.
+After plugging it into an USB it mounts a D lettered drive with 63MB stuff in a folder called image with *.mdt files, modem files( I can screen it if it's important )
I'm clueless, never happened to me even though I flashed a lot of roms, I think I bricked it. Help?
UPDATE: I managed to quickly release Volume Down And Power buttons when LG appeared for half a second and hold it again, succesfully booted into TWRP. I haven't bricked it I think. Will tell how it goes <3
Hey man, how'd it go?
I'm in exactly the same situation as yours, can boot into twrp but nothing else works, i fear of the qhsusb_bulk brick but these people don't even seem to have recovery.
Any suggestions? Go back to stock? How?

How did it go!? I'm in a similar situation (but can boot into download-mode). Would love to get back to twrp, since I want to give it a try to flash another cm (stable). Thanks for sharing your experience...
If its picking up bulk mode normally its hard bricked there is a guide for restore nearly all g2s from hard brick having done it myself included 1st time took me a week to get back up but. Now i prob take about 45 min just cause i aint had one in a while

Hey there, can you specify what you did exactly or where to find!? Do you mean something like this? (can't post outside links, in XDA-forum, title is "LG G2 is UNBRICKABLE NOW! [FIX REAL HARD BRICK]") Thanks for help...
Yes thats it. Lol i still got the files on my pc for my g2 i keep the whe setup cause im on the g3 now i just check in the g2 forums cause i had mine for 2 years and modded the crap outa it but yea i keep all the files on hand so if anything ever happens i can fix it almost on the fly now
Well so what happened to me that I managed to get inside the TWRP. When it lighed it up for a second I quickly released and held again that got me inside magically. So then I just transfered new rom and tried to install again. Sadly I didin't see that the ROM Im trying to install requires bump TWRP and I bricked my phone again. Though I entered download mode and flashed the stock rom through LG G2 flasher.
heres a video i made, how to go into recovery. for those that cant get in to twrp.
