Guys I'm sorry for this idiotic question. I've just run into nothing but frustration trying to get back to stock. I've followed these threads:

http://xdaforums.com/showthread.php?t=2448960

http://xdaforums.com/showthread.php?t=2471370

With both threads, every time I get into download mode, this happens:

In reading this thread, it seems like you have to hit volume up, down, and power to get into download mode. As far as I know, the Verizon version just requires you to hold volume up and power. DO I actually have to hold down all 3 buttons? Or is this for other variants?

Every time I try the download mode, I see the download mode logo but then it goes right into the Firmware Update screen. I've tried a PC running Windows 7 64bit and a laptop running Windows 7 32bit.

I'm just trying to figure out how to get back to stock in case I run into a problem. Could someone point me in the right direction? I'd seriously appreciate it.

Make sure you have LG drivers installed. Download from here

Then boot into download mode.

Or else, use a different computer, install LG drivers and try again.

HELP!!! - Bad TWRP Flash and Accidental OTA

I'm trying to go back to stock to repair my G2. Here is the problem:

Previously attempted to install TWRP on the AT&T LG G2 and got the boot screen error: Boot Security Certification error, so TWRP Recovery doesn't work. On top of that, I accidentally accepted thee latest OTA (I know...dumb). Now I cannot get the phone to boot into normal state. It keeps going to the boot screen with the LG logo and displaying the "boot certified error".

I can't figure out how to flash back to stock as holding down the volume down doesn't seem to get me into download mode. Any help appreciated as I'm bricked.

Thanks
[G2 General] Elroyy:
Back to stock and unrooted. What I did was find a rom that was based off stock. Luckily, someone posted a Bell, stock rom in zip format. I installed that with TWRP. Once installed, I ran through the OP steps and was able to get the stock Telus kdz installed. The bonus is that the Telus and Bell software are apparently very similar so I didn't even have to factory reset. I'd like to thank everyone in this thread.
[G2 General] rafaelsartori:

If I use one of these methods after flashing custom roms does it mean I`m fully back to stock, no way finding out that I flashed custom roms before, and I`m able to get OTA updates ?

btw [MENTION=2607037]hyelton[/MENTION] I have seen your posts all around the xda..you`re helping people when ever you can.. thanks for that.. its nice to have you with us.
[G2 General] hyelton:
Yes it puts it 100% stock as if you never touched it :)

Your welcome :)
[G2 General] SamsungIsBetterThanApple:
[MENTION=2607037]hyelton[/MENTION] is awesome! Your guide fixed my bricked phone. Thanks so much.
[G2 General] Brontok:
thanks bro.. why do you think my phones says its rooted after installing stock kit kat rom.. ? this happened even the first time, when I bought a brand new g2..i went from stock JB to stock KK using LG Flash Tool and in download mode it said "rooted"..when I install stock LP rom it doesnt say its rooted.
[G2 General] ugslick:
Seems like it's stuck...

I want to revert my LG D803 back to stock so I can put on a kitkat ROM instead of Lollipop (gives battery and heat/performance issues). With the D803 I had to flash a partition patch to get the ROM running, and so I can't simply go back to an older ROM without restoring my partitions. I'm doing CSE flash with the KDZ method as you've guided OP, when running it seems to get stuck here:

Right now it's at about 49 minutes. When it first started it was running the driver download by itself (I'm assuming your flash tool does that automatically), the one you see now I ran the LG mobile drivers tool by myself. Perhaps relevantly/notably it was able to download drivers for two things, but I think it failed for LGE Modem (or something like that). Is that causing an issue? I'm too scared to try unplugging and restarting. What do I do from here? Should I just let it run (it seems like it's stuck, and I can't read anything...) There WAS a dialog that popped up, but I again couldn't read anything. I clicked the box that said ?? ?? and then it continued..... now it's been like this for a long time. Should I click the button in the bottom right corner?
[G2 General] hyelton:
That's because kitkat had a glitch. You could had gotten a brand new phone or referb that Had kitkat and it would say rooted. When it really was not. Downgrading the jellybean fixed that.
[G2 General] hyelton:
If you've waited 49 min it's clearly not flashing. This only takes about 10min max. Just check device manager. If you see Lge modem or lg serial under complication ports of not then it's a driver issue. Or if your running windows 8+ make sure you unhide ports.

We don't know if there's an error because you never set the apps language to English that's why there is all question marks. Also make sure your using a USB 2.0 port and not a 3.0 port.
[G2 General] ugslick:
Your guide did say that the language would automatically be set to English... so I didn't change it manually :P Yeah, I can see the device in manager. It seems to be working/recognizing it fine. Should I be using TOT method? I'm downloading the D803 TOT zip file (contains both stock image and DLL file?) right now... I guess I'll cancel the Mobile support tool and then take my phone off usb connection for now.

When I click the little button in the bottom right it gives me a bar, goes to 2% and then returns to the regular interface. I have been reading a bit in the thread, and it seems like CloudyG2 3.3 is the issue?

Thanks again man.
[G2 General] hyelton:
Yes if your running a custom rom like cloudy that can be your problem. And you'll need to do the tot method. Make sure you rereboot your phone in download mode before retrying each time or it might not work at all.
[G2 General] ugslick:
I didn't initially see the TOT files for D803 so I didn't try it (it's one zip file among the 7 or 8 kdz files), but after watching the video I saw that 'supports D803'. Currently downloading files, and then I'll go ahead with that. My phone booted normally, so I'll reinitiate d/l mode once the files download. Thanks again, and sorry for the bother :)

Hallo. I've downloaded the first and third files in this link "//Xda/LG G2/Stock/D802 tot/" on different pcs but on extracting am getting the corrupt file error. Am frustrated because that's data wasted. Anyone assist me with a link to the tot file itself for my 16GB D802 instead of the .exe? I need to get my G2 working again as it's currently playing dead.

Kindly help.
[G2 General] hyelton:
Are you using a download manager? If not do that. The links work fine and have been used thousands of times. If it was corrupt id remove it.
[G2 General] scipion_s:
Hi, would like to ask for some help :)

I've got an LS980, did a root and permanent unlock, then I started the OTA update and it stuck into the boot logo/updating process. Hard reset does nothing so as I understand I need to flash it back to stock but can't understand which exact Sprint ROM I will need and how I can check it. Or is there something I'm completely missing and should do the other way? Sorry for the noobish questions since I'm new to this :o and any help highly appreciated :)
[G2 General] hyelton:
You can flash any of the sprint ones. Just depends what version of android you want.
[G2 General] scipion_s:
Great, big thx for help, just one more question, which is what version? :)
[G2 General] rabbit19:
Hi. I've been trying to download the tot file for LS980 the whole day but haven't got any luck...

Any new link?
[G2 General] hyelton:
In the OP. Link works just fine Downloads in under 3 min for me. If your having problems or have a slower ISP always make sure you use a download manager.
[G2 General] hyelton:
Don't keep up with Sprint's versions (There confusing at times) Sorry. Which ever has the highest number/letter would be the latest that I have.
[G2 General] rabbit19:
Thanks a lot. will do that. I woke in the midnight just to try if I can already download it, but still ain't going anywhere. Will now try IDM.
[G2 General] hyelton:
Something like that id blame your ISP for. That's strange.
[G2 General] rabbit19:
I think so. I was able to download the dll files from the Sprint folder, but no luck with the ROM. Now after installing IDM, still ain't working, so I used Hotspot Shield and it's downloading now. Thanks for the help. Hoping to have it restored later. I bricked my LS980 when I installed DormanX to have faster charging. Unlucky because the stock rom was deleted due to erratic or ghost touches a day ago. Mine was already on G3 ROM, but the DormanX should be installed on stock ROM only.
[G2 General] hyelton:
Yeah if it's working after using hotspot shield for some reason your internet provider is acting strange.
[G2 General] rabbit19:
Hmmmm... I guess it has something to do with the Net Capping. My ISP only allows around 800mb download per day. What a shame hahaha.
[G2 General] hyelton:
Ouch :/. Doing game re downloads on 3computers in two days I did 200GB
[G2 General] kahush:
Yes. I used IDM in both instances yet I ended up having corrupt files, my connection is always stable and fast. Let me ask this, does the operating system I download on matter?
[G2 General] hyelton:
How do you know it's courpt? When extracting? No it doesn't matter what OS as long as your not using a phone or tablet to download it.

Also malware or a virus can cause zipped files to be corrupt upon download.
[G2 General] kahush:
Yes. When extracting the file I get a crc error.
[G2 General] hyelton:
Try and do it on another computer. at this point I'd blame the computer for that issue.
[G2 General] G-diddy:
I just followed the .kdz option for my vs980 39a and was hoping to see the "Sofware Status" returned to "unmodified" but mine still says "modified." I need to return the phone and don't want to get denied because it was rooted. When I purchased the phone it was still on KK and I OTA'd to Lollipop. I had tried several Lollipop ROMs using xdabbebb's 39a bootstack. I was running LP pac-rom when I kdz'd . I noticed on the download mode screen that it listed the boot as 27a. Was that an issue? Can I .kdz to KitKat? Would that fix the software status "modified" problem? Please help.
[G2 General] hyelton:
It depends. The G2 had a glitch with kitkat. Even factory phones showed modified or rooted while in download mode even when they wernt. You can downgrade to JellyBean and that should fix it.
[G2 General] G-diddy:
Thanks for the tip. I'll give it a try. 24a download is uber slow right now. Probably just a high net traffic time of day here on the west coast. Hope it works. I bought a refurbed g2 off of amazon and a dead spot showed up on the screen just out of the 30 day return window. Crossing my fingers that the seller will still let me return it. Any tips for dealing with dead spots. I've replaced a screen on a different phone with success, but I'm really good at breaking stuff and would rather not poke around inside too much. I did try resetting the ribbon cables, but I still have the dead spot. Anyway, I really appreciate all your help. You are very knowledgable. Thanks.
[G2 General] hyelton:
Use a download manager. It helps download speeds :). Well with LG its honesty a pain. The phone store ive helped out don't like touching them for screen repairs. I can do a iPhone 6 screens all day long. But the G2 I wouldn't even want to try lol
[G2 General] naxsandbew:
is this lolipop ? D80230B

can i flash this :confused:

i'm on rooted kitkat TWRP
[G2 General] hyelton:
Yes assuming that you have a D802 32GB. There's multiple models.
[G2 General] G-diddy:
Just an update on the "software status." I tried flashing 24a but didn't realize that I didn't have the full download so it failed. I flashed the 39a again and checked the software status and it now says "Official." Thanks for your help.
[G2 General] renatotec:
I'm getting "CrossDL [] to [D805]" and can't flash... Even with .dll supplied. First method with LGFlashTool2014 can't be done too due to "stop on 49% error"...

:(
[G2 General] hyelton:
That would be because what's on your phone currently was not meant for your model or is based on a different model. If you still have twrp flash a rom that's specifically built on your model. If not you need to do a hex edit on the tot file.
[G2 General] renatotec:
Don't have twrp anymore, only download mode....
[G2 General] hyelton:
Then you'll need to do the hex editor method.

secure boot error on D800

I have a d800 that was happily running cm11, then cm12, and then I botched the update to cm12.1. I installed what I thought was required ("bootstack-d800-LP_30d-loki-signed") and was stuck in a boot loop. Then I installed "bootstack-d800-LP_30d-Bump-signed" and now get a secure boot error.

I've read all instructions in OP and downloaded all files. My intention is not really to get back to stock, but just back to functional. Is there a practical way to repair the bootloader/kernel, or should I go back to stock first, then repair from my cwm backup?
[G2 General] hyelton:
The best way is just to go back to stock at that point. Unless your able to flash a different rom via recovery.
[G2 General] Jeik:
Hey! Me again! :silly:

So I dared to change my filesystem to f2fs,while using the TWRP Bumped with F2FS support.

First I flashed CM12.1,and got a secure boot error(I had a feeling CM didnt support f2fs,but I tried anyways :P),and then flashed SlimSaber,which booted.

It was all fine and peachy,but the recovery was acting nuts.

If I were to try accessing it with the "Quick Boot" app,it would show the TWRP logo,and then immediately forcefully restart the phone.

On the other hand,if I tried to access it with the key combination,it would "boot". But if I tried to wipe anything,and sliding the confirmation slider,the phone would vibrate and forcefully reboot. Same thing when trying to flash anything.

So I guess the F2FS supporting TWRP actually doesnt support F2FS?

Now I have to go back to stock to have my partition back to EXT4,right?

EDIT

Oh,and by the way... Is there any way to determine if I have a 16GB variant or the 32 GB variant?

I got the phone pretty much blindly,but it was 16 GB when I got it.

I dont have the box,but is there any specific thing,IMEI or codename on the back,that tells me what I exactly have?

EDIT # 2

My phone is detected as "LGE AndroidNet USB Serial Port",while the screenshot in the OP shows that the proper one is "LGE Mobile USB Serial Port".

Okay,the KDZ method worked. The phone is alive again.

Is "LGE AndroidNet USB Serial Port" good too?

I know I am a bother,but I forgot the procedure...
[G2 General] UserofAndroid1813:
Hi. ZZTrying the KDZ method, the LG Flash Tool gives an error, but doesnt explain it. Is there common errors I can fix
[G2 General] hyelton:
Lge serial or Lge modem same thing. It just depends on the current software version and or driver one or the other it's the same :)
[G2 General] hyelton:
First of all explain a little :p. Model? What are you flashing? Made sure Lge modem or lg serial shows up under com port ? Flashtool set to English? As in what's the error your getting? If it's the cannot connect to server that's normal and just move the window. If it's something else it could be related if your running a custom rom and in which you would need to do the tot method first.

[G2 General] hyelton:
The server error is Normal and doesn't cause any issues.
[G2 General] UserofAndroid1813:
I am not getting just a server error. Here is a photo of the error. TOT method doesn't work either for my LG G2.

Device

-Running VS98039A Lolipop Stock everything

-Verizon LG G2 32GB Model

Computer

-Has all Drivers

-Runs Windows 10 64bit
[G2 General] hyelton:
If your running stock then why are you trying to flash it?? Also why doesn't tot method work? You changed the com port to com41 right?
[G2 General] UserofAndroid1813:
I wanted to downgrade to KitKat from Lolipop. The code was about a wrong model. And yes changed the COM

If KDZ can be fixed, Thad be a lot easier
[G2 General] hyelton:
If its saying wrong model that means your either trying to flash a wrong model. Or whats currently only your phone is not stock.
[G2 General] UserofAndroid1813:
Well I guess I will try downloading the TOT again. I am absolutely sure I am running stock Lolipop. So if this don't work I will try factory reset (I guess) and then try to downgrade again.
[G2 General] hyelton:
Factory reset won't change anything if your not running stock. Let me know what model it shows you are in flashtool when it gives the error.

LG G2 touch screen problem

I update my phone software from kitkat (D80220b) to lollipop (D80230A) everything was successful but after the phone get updated my touch screen was not functioning properly.

whenever I try to touch the screen, phone detect the touch at a inch away from where I touched.

then I reinstalled the stoke ROM which was previously installed on the phone but touch screen is still not working.

please help me to solve the issue
[G2 General] Jeik:
Hey,I bricked my g2 yet again,and I was wondering. The KDZ magically doesnt work anymore(it did yesterday,on the exact same PC and ports),the same error as UserofAndroid1813 ,so I decided to try the TOT method.

I have a 16Gb variant(I think,since the storage was 16 gb,but the device couldve been 32 GB before,which I do not know),and I downloaded the 32GB variant TOT file. Is it safe to flash,or do I have to downlaod the 16GB variant TOT?
[G2 General] trinityftl:
Device bricked need to find a fix or a way to fix

I have a AT&T LGV410 G Pad™ 7.0 LTE-V410, I also have access to another LGV410 G Pad™ 7.0 LTE-V410 that isn't rooted or bricked.

State of my bricked device is as such, I am able to boot to cyanogen recovery and even sideload a ROM without any results. On a sideload it went to 47% then just ended. I am not able to access fastboot menu, when I try I get a LG Security Error screen which then goes to a battery charging screen. I am able to access the reset to factory default screen, but when I attempt to actually do it, it just reboots to recovery. When I try to go into download mode, a screen pops up saying hold the volume up until download mode is reached, it then reboots and comes back to the same screen.

From recovery I can only access side load thru ADB, any other state says device is off-line.

I know the laf img was deleted then replace with an incorrect img, this is where the LG Security Error screen comes from and the I could get into the fastboot before the laf was replaced.

Do I neeed to send it back to LG or is there a way to fix this? I can do my repairs in either Windows or Linux so a step by step repair or step by step root and copy the working LGV410 over to the bricked LGv410 would be greatly appreciated.

After I originally rooted the device, I left it on and came back and the device was stuck in Fastboot (bootloader) which was locked, I was able to unlock and install the cyanogen recovery without any issues.

UPDATE: After much more searching and testing I have discovered that when the device is powered off and I plug it into my computer I get this for the device Unknown USB Device (Configuration Descriptor Request Failed)

I have deleted the drivers, uninstalled every USB controller, tried forcing it to use different drivers and I am having no luck.

Also I can attempt to start download mode, it gives a first screen that says keep holding volume up until you see the download scree. The LG Security Error screen, I can keep holding volume up and it loops between the 2 screens. Also while attempting to go into download mode, there is no usb connection attempts being made to my PC. I have tried this on a windows 10 and windows 8 machine with similar results. Any help would be appreciated, I have contacted LG for service.
[G2 General] hyelton:
Are you sure you have a D802? And did you perform a factory reset? Touch screen issues like that are usually due to flashing wrong model.
[G2 General] rabbit19:
HI Again. I was able to flash to kitkat, but was upgraded to LP. It was simlocked so I tried to edit build.prop, it all got messed up, and not it's bricked again. I tried to redo your procedure but I can't flash it anymore using kitkat, it's only up to "waiting for connection". I can still go to download and recovery mode. PC also recognized the G2, and I placed to LS980VE rom to root directory. Should I proceed with restore using the zip file? thanks
