That does not matter for this, If it was missing a driver that was required it wouldnt know that the incorrect software is installed on your phone, it would just still say ready.

Have you tried this?

I can get into download mode no problem. For some reason these methods just hang mid way through, or for TOT it just won't even connect once I get to download mode.
[G2 General] hyelton:
Its all go to do with that rom, If you could get CWM or TWRP we could format system and fix this!

Follow this guide and put recovery on it.

[G2 General] kkevin94:
Hey man, great work and thank you for this. I'll be even more grateful after it actually works. I set everything up according to your specifications for the Tmobile variant. But on the flash tool i get no errors, everything looks good, COM41 shows Ready! in a yellow box, and nothing happens. My phone does nothing. I havent bricked my phone, I'm just trying to get down from official KitKat. Help please?
[G2 General] hyelton:
Phone in download mode? If so restart the phone once again in download mode then plug in and it should start flashing :) Make sure to click the yellow arrow as well

Let me know!
[G2 General] :
If you still have a custom recovery installed just wipe system and everything else then in dl mode it should show up as the correct device. Had that happen to me before and thats how i got through it
[G2 General] hyelton:
Yea, but he doesnt have a custom recovery nor root. , thats what we are trying.
[G2 General] kkevin94:
Ok. Here's a question. Is it supposed to say ready BEFORE clicking the arrow, or AFTER? Because it's in download mode, it says "do not unplug until its complete", but it never moves from 0%.

EDIT: Screenshot. Thats what it looks like after pressing the yellow arow and nothing happens, even after reentering download mode.
[G2 General] :
Isnt there an adb method to wipe system ?
[G2 General] kkevin94:
Thanks for your help. I'm an idiot. I never saved me setting to put it at COM41 in device manaager. Sorry. But thanks for eveything! It worked!
[G2 General] hyelton:
Awesome :) glad to hear!
[G2 General] buenarc:
Wow I think I can do this. thank you for the step by step process.
[G2 General] RobHands:
Kinda going nuts right now, I'm stuck at "upgrade start", instead of "Select Country & language" the software just opens and shows that the phone is up to date (and I'm running cm 11). Why is that?
[G2 General] hyelton:
So you followed the guide entirely? Vbs script and change host file?
[G2 General] RobHands:
Yup, at first ran into some issues with the vbs bc of the anti-virus software.

[G2 General] mackster248:
That guide requires that I'm already rooted in order to do that. :(

I think I'm out of options. :/
[G2 General] masri1987:
and when i try the TOT method the lg flash tool stops responding and windows asks me to close it. any ideas? i literally get to the last stop and boom.
[G2 General] Zulake:
Well, seems this method no longer works for me at least. :confused:

I have done it a lot of times in the past, always worked, and now it suddenly doesn't anymore.

Sometimes it gets past the 'please update' screen, but in that case I will get this:
[G2 General] hyelton:
Make sure you removing it and starting over each time for it to work. What do you mean in the past?,how long ago? The guide changed a month or so ago
[G2 General] just4kix:
I"m in the exact same boat as you. I've tried all these methods and nothing has worked. I didn't flash superSU after flashing CloudyFlex and now I don't have root, no recovery... I get the exact same error [G2] to [D801]... I wish there was a way to just force brick this thing so I can take it back in even though it still says Rooted in download mode...
[G2 General] mackster248:
Damn, sorry to see you're on the same boat as I am. All we need is to get root on and we'd be good to go. I think our last hope is to just PM Cloudyfa and ask him if there's any way we can root it.
[G2 General] buenarc:

[G2 General] rodpgfx:
Hey guys,

I've been doing everything it asks and I know it's right cause I had it work before.

Every time I try to use it now it tells me to update the R&D test tool......

I am running a D803 variant so I'm using the Script method.

I tried the host method and that don't get anywhere....

Any ideas?
[G2 General] hyelton:
You'll have to change your hosts file for this to work.
[G2 General] hyelton:
Why is it not rootable? That's just odd to me.
[G2 General] mackster248:
Thanks man, I'll PM him and report back to you as well if he responds.

It's really odd to me too. But I think it's because it's a stock ROM, so ioRoot25 won't work as it only works for factory based ROM's. :(
[G2 General] rodpgfx:
So even though I'm using the Script file, I still have to manually add the lge.mobile.com in the host file?

---------- Post added at 12:55 PM ---------- Previous post was at 12:44 PM ----------

[G2 General] maddog497:
Is this a Canadian phone?

If so I was successful by just using the LG update tool.

I don't have a very fast internet connection so the whole process took over an hour as it had to download the KitKat update from scratch, but it went through without a hicup.

[G2 General] hyelton:
What ROM was your running have a custom recovery?
[G2 General] rodpgfx:
I was running cloudy 2.1 and I had twrp 2.6.3.4 (latest one for Canadian variant)

After installing cloudy 2.1, the phone froze so i done hard boot and twrp was gone......

So now I'm trying everything to restore stock. Kitkat (legit) or original firmware (offline files)

Can't get anything to work for me. Keeps getting same error.
[G2 General] mackster248:
I get that same exact error as well when trying that method. I think when you're on a custom ROM with out custom recovery, this is what happens. :/
[G2 General] rodpgfx:
I've been on lots of custom Rom's before, and easily flashed back to latest stock with lgsupport tool. not working this time.....
[G2 General] mackster248:
Same here, I've used the flashtool numerous times before, that's why I think I'm screwed. If my phone didn't have that weird white line glitch, this never would have been an issue. :(
[G2 General] hyelton:
Seems that the problem your getting is from running Cloudy I`m not sure why not bashing the rom or anything never tried it but seems like everyone that was on it thats tried flashing back to stock has not worked for them. There was serval people yesterday that used the method including my self the other day so the method is working, but it seems people running Cloudy is having an odd issue.
[G2 General] rodpgfx:
Well thats lovely! This will never get resolved.......

I've tried everything, no way will this phone allow any other Rom's/firmware to install.....

Gets to 49% and thats it!

Who the hell made cloudy anyways, they should be looking into this
[G2 General] hyelton:
Of course I was not blaming them, But it could be a possible reason no one knows for sure. Unless we get more coming here. I stayed up pretty late with some possible ways to fix but nothing yet, But I wont give up!

I would give to some advice for people who WANT to flash back to stock if they see this.. If your RUNNING Cloudy or ANY rom for that matter, be sure to FORMAT not wipe FORMAT system in your custom recovery before flashing. I`m 99.9% sure that formatting system in recovery would allow you to get past 49% if you can find a way to get custom recovery on it, Maybe try putting the phone into Fastboot mode to load recovery if thats possible??
[G2 General] rodpgfx:
I'm not even sure i can boot into fastboot mode. I know to install recovery on this phone I have to copy .img file to phone and do script in terminal emulator. So not sure i can install in any other way.

Thanks for working on this, I'm sure more than me will be so happy that you've fixed it.

Thanks again

---------- Post added at 02:09 PM ---------- Previous post was at 02:06 PM ----------

I sent a PM to the guy who created this Rom, and he was very "helpful" in getting me back on track!

This is his "helpful" words to me!

"I have no idea why you have the issue. To make it clear, you must do something else to put yourself into current situation, my ROM doesn't include any partition such as recovery, only system + kernel and its pretty safe."

Service with a smile......:rolleyes:
[G2 General] hyelton:
The person may not have a clue I`m pretty sure they did not mean to cause harm to anything.

Anyway we need to work on getting a Recovery back onto the phones so we can format data.

EDIT: I think you can flash a Custom Recovery via fastboot as you can do adb commands to load up a .img file to the phone. I think I used Fastboot to load recovery on my Nexus 5, But After some googling its possible to do so in fastboot mode./
[G2 General] hyelton:
This:

Try this! and update us!
[G2 General] rodpgfx:
That would be nice.

When i try the vol - and power button, it takes me to the white screen where you double click format phone, which should take you to twrp, but now it takes me to fastboot mode I THINK and says "secure booting error, Cause: boot certification error.

Then it takes me to blank screen and I have to hard boot phone.

Not sure if this helps you.....
[G2 General] hyelton:
Maybe the blank screen is fastboot mode? I know on my G Pro when running anything custom it would ALWAYS say "Secure Booting Error" But was not an issue as it only said that casue it was not stock there really was no error.
[G2 General] rodpgfx:
So you think I should try to flash recovery in fastboot mode?

I forget how though.......fastboot flash recoveryfile.img /sdcard/recoveryfile.img??????

I'm not sure. I remember something like that from the HTC one i had.
[G2 General] hyelton:
Try and Google around about it that's all I can say. I think some people have done it on there G2 but look around Google.
[G2 General] rodpgfx:
I've entered into what we think fastboot mode is, but when i connected to computer, about 10 "local disk" came up and in the device manager it's showing a "QHSUSB__BULK" which needs a driver......

I dont think this is fastboot mode.....
[G2 General] h9s:

[G2 General] masri1987:
So i'm using LG Flashtool, and i reach this... do i just leave it as it is and give it time?
[G2 General] hyelton:
What rom are you coming from ? Stock or something else?

If you have a custom Recovery be sure you FORMAT System before flashing.

Make sure to reboot your phone into download mode and plug it in and if it does nothing make sure your changing the COM port to port41 in device manager.
[G2 General] masri1987:
i'm on flexrom hybrid and i have twrp 2.7 , let me format system and retry,

as you can see in the photo, com41 is ready to go
[G2 General] hyelton:
I was meaning you need to check device manager to make SURE the phone itself is set to COM41
[G2 General] secret.animal:
White line issue has nothing to do with ROM. It is something to do with partitions when either aboot gets downgraded or non stock kernel
[G2 General] masri1987:
Do I check that whole phone is on and connected as mtp? Because in download mode I don't see phone under USB in device manager
[G2 General] babysmoker:
Just wanted to chime in... Cracked the screen on my vs980 (VZW) (rooted with custom recovery) a few weeks ago in such a way that only half of the LCD is touch responsive. Well last night the time finally came to reset & send in for warranty.... No matter WHAT I did I couldn't get .kdz file to flash, it just kept checking for a new version of LG Support Tool or whatever after selecting "Upgrade Start". It might be worth noting that I'm running Windows 8.1, but disabled all anti-virus including Windows Defender & all that crap. After trying & trying I finally threw in the towel for the night & let the TOT method files DL while I was asleep. Woke up this morning, followed every step to a T..... & the TOT method worked FLAWLESSLY! So first off I just want to say THANK YOU THANK YOU THANK YOU to the OP!!!! & [MENTION=2694397]masri1987[/MENTION] - if you haven't done so already, you need to go in to Control Panel/Device Manager ON YOUR PC (NOT IN THE LG FLASH TOOL) scroll down to Ports (COM & LPT), select your Android device (make sure it's plugged in via USB), go in to the advanced settings & change it to COM41 (mine was set at COM05 before I changed it manually). Really hope that helps... best of luck!!!
[G2 General] SuperSport:
Watch my video here. It will help. http://youtu.be/Lg693AYgoTo
[G2 General] hyelton:
It will not show up as mtp. Download mode is something completely. It will show up as a com port and you'll need to change it.

Most of the tot not flashing issues are related to not changing that option
[G2 General] rodpgfx:
Any headway on it yet?

I've checked out a post about going into Ubuntu and installing some files (overwriting) but I can't even get the phone to recognize.

Changing boot.img files that come with the rom file.

http://xdaforums.com/showthread.php?t=2582142

Didn't help me, couldn't get very far
[G2 General] RobHands:
OK tried again today and still no luck.

Here's my procedure step by step.

Downloaded everything, installed LG Mobile support tool and deleted it afterwards from ProgramData and replaced it with LGMOBILEAX. I double checked hosts file, aditional line is there.

1. Start the VBS script

2. Click on Windows Enabler in Taskbar so it's set to on then click ok on the dialog box.

3. R&D test tool opens automatically and I can select kdz and click normal web upgrade test

4. Upgrade start

here's what's very confusing, instead of the dialog box where I can select the country and language, the support tool just opens normally and checks for system updates :eek:

Has this something to do bc I'm running CM and not stock LG rom?

[G2 General] rodpgfx:
So what I'm doing now is making backup of what I got working now, then I'll transfer that to my comp and go back into recovery and format/wipe system, right?

Then I should be able to flash stock firmware with support tool.....
[G2 General] hyelton:
Yes you should be able to. Now there's then normal wipe you do when flashing ROMs. But you'll want format system which is usually under advanced or something it removes the entire ROM making the phone in clean slate. I'd put a flashable ROM on your storage just in case for safety.

[G2 General] hyelton:
Not sure what you mean
[G2 General] rodpgfx:
I thought the OP was for people who wanted to flash recovery to g2. If I can install stock firmware and root, then flash recovery we wouldn't have to downgrade stock firmware first.

I don't mean any disrespect or anything, just saying this new "aurorec" file will do recovery for us right from stock firmware.:good:

Yeah, so advanced wipe, then click boot, data, system.....
[G2 General] hyelton:
No this entire guide is to go back to stock completely lol. The OP is to return to 100% stock. Unroot , stock recovery , stock firmwares from the factory. Or if a person bricked there phone
[G2 General] rodpgfx:
Oh lol. Sorry bud. There's more to the OP than I realized.
[G2 General] hyelton:
That's why we should all read:D. Ive miss read things as well :) it happens haha. Yea the meaning of this guide is to go back to stock everything.
[G2 General] rodpgfx:
hyelton, I just booted up the support tool and the software showing is still cloudy.

I'm not taking any chances, I'm gonna install this OptimusRs Rom I have first to overwrite anything to do with cloud Rom, then I'll do flash.....

I'm making sure it works this time lol

P.S. - I can't thank you anymore lol. It's saying I'm only allowed to thank 8 times a day :silly:
[G2 General] hyelton:
Haha. Your welcome :). If you formated data it shouldnt show your on anything at all. Just be careful when under advanced there's other options that can be damaging.

LG_KDZ_FW-Update_Offline.zip is malware??

Hi all happy G2 owners.

I'm trying to flash a stock 4.4.2 ROM using .kdz

So if I understand this right, one of the tools I need is the "LG_KDZ_FW-Update_Offline" but everywhere I try to download this from, my Chrome browser says it's malware, and my Chrome browser blocks it...

Anyone else seen this? Where can I get this from, or is there a simpler way to flash .kdz?
[G2 General] hyelton:
This is the only way to flash a kdz. Yes it happens. You need to Google how to disable that problem in chrome or use another browser to download it. Its the file itself. Chrome things its malware cause it has a web server in it
[G2 General] guvno:
But it is a safe tool to use, right?

---------- Post added at 07:16 PM ---------- Previous post was at 07:02 PM ----------

[G2 General] guvno:
Hmm, well I do have a LGP920.dll file in folder "lg-kdz-fw-update-offlinefix\KDZ_FW_UPD_EN" after unzipping. Could someone have "hacked" your guide/zip package? Is there a safe place to get it from?
[G2 General] hyelton:
.... No thats not possible... If you read the guide, ALL FILES ARE HOSTED on my server.. The file is safe. At first it seemed like you where getting files somewhere else for another phone. Look how many pages this guide is if there was something wrong/hacked/broken/virus It would had been shut down by now.

This guide is working and safe I understand your trying to be safe and everything but you can take my word and everyone will agree the file is safe. :cowboy:

That's a very odd way of doing it. Its still the SAME method. You still have to go through flashtool..
[G2 General] 6ril1:
You can think that you want about this method but, please, stop to says there is not another method for flashing kdz than OP, it's false...

This method you find odd is 100x more easy than editing host, emulate web server, trying to launch vbs with admin right etc...

It uses only LG Mobile Support Tool and doesn't need to be offline. No need flashtool either, just LG Mobile Support Tool...
[G2 General] hyelton:
When I say theres no "method" it pretty much means there NO simple way of doing anything.

Also no it does not work as easy as it sounds, If your running another rom thats not meant as in your phone is running a rom meant for a D803 But you have a D801 flashtool wont do that method.

Also the TOT method here is the ONLY way to Flash AT&T & Sprint theres NO other way, The TOT is also recommended for the D801 T-Mobile and Verizon version as well over the kdz

Yay KDZ method worked! I used a Kit Kat KDZ, many thanks.
