I have actually used the KDZ method and I am now on the stock Lollipop ROM, but I am having some issues with the GPS and I remember someone saying that the TOT method is preferable instead of the KDZ, to flash after certain custom ROMS...?!

Google Maps keeps saying 'Signal lost' and showing me off course, and I don't remember it doing that before with the stock ROM.. Also, in Feedly, when I open the left drawer and flip through the sources list, it doesn't keep scrolling after lifting my finger off the screen, and this is strange.. I don't remember the stock ROM doing that.. But my previous custom ROM did that, with certain CPU freq/governor settings.. It's really strange..
[G2 General] hyelton:
Flashing a tot won't make a difference. For a D802 you should only need to use the tot method if the KDZ method doesn't work, which in cases where some custom roms KDZ method will fail. But other wise it won't make much of difference besides you'll be flashing an older firmware with the TOT. No clue about apps like Feedly. If it's not a stock app the phone itself has nothing to do with those issues.

Did you perform a CSE flash? And a factory reset?
[G2 General] teomor:
I didn't have the CSE option when I did the KDZ flash.. It just wasn't there, so I did the normal one. But I did do a hard factory reset a few days after flashing, to see if anything changes, and it didn't.. Still have the Maps and Feedly issues..
[G2 General] hyelton:
Your really supposed to do CSE flash to fix any problems. The option is usually not there if you changed the type setting from cdma, your supposed to leave it set on CDMA.
[G2 General] teomor:
Gonna try that again. But I'm pretty sure I left it on CDMA.

OP,

Thank you x 1,000,000!

I was sure I bricked my phone!
[G2 General] Bn Waheed:
i am getting this problem any idea what should i do?
[G2 General] hyelton:
Did you set your LG com port to com41? Also using USB 2.0 and not 3.0 right ?
[G2 General] jim_0068:
I have a verizon G2 rooted/TWRP recovery still on jellybean. I want to flash stock kitkat (not lollipop), what would be the best method to do so? Go back to stock using this method or just straight flash the roms and i think i need to upgrade the baseband to? Not sure.

Thanks,
[G2 General] hyelton:
What do you mean straight flash roms ? Straight flash what? You cannot flash these firmwares without flash tool
[G2 General] jim_0068:
So i can't use TWRP to flash a stock OTA? I need to use this tool to go back to stock and then use the flash tool to flash OTA kk? Just didn't want to do extra steps if they weren't needed. There are so many guides out there it's hard to figure out which one is the right one to use :-\

Thanks for the fast resposne
[G2 General] hyelton:
What do you mean flash OTA? You do OTA on the phone not by flash tool.
[G2 General] jim_0068:
i'm referring to the OTA Rom. Because i'm rooted and have custom recovery an OTA won't install, so i'm trying to figure out the best way to install the factory verizon OTA kk but still want root and custom recovery. So do i have to go back to stock completely, let the OTA download and install then root/install custom recovery? Also isn't the most recent OTA lollipop? I'd prefer to not upgrade to lollipop. Hope that helps & apologies if i'm not explaining myself correctly.
[G2 General] Bn Waheed:
yes i did set the port to com41 and i am using usb 2, it's the first time to flash a LG device and the device i got has no rom on it, just TWRP recovery and it hangs on the LG logo

EDIT: Worked after charging the phone

Sprint - Boot Loop

Can someone help me here.

I'm stuck on the TeamWin Recovery after I stupidly updated the Sprint OTA update.

Trying to use the LG Flash to fix my phone, but can't get the Sprint .tot to flash correctly.

not sure, if I'm going down the right path to fixing it? Suggestions? I have a useless phone at the moment.

thanks!!!!

see my other posting: http://xdaforums.com/showpost.php?p=48302833&postcount=265
[G2 General] rafaelsartori:
did you already had any kind of custom recovery? i dont know if with the original recovery we can do those wipes.

try this, shutdown your phone --> Volume down & Power, when the LG logo appears release and press them again --> then press the Power button three times!

that way you will enter on recovery mode, if is the stock one, it will try to do all by itself, if is a custom one, you will access it and gain access for those wipes that you need.

after all, shutdown and enter on download mode to try again the stock flash.

Hello can someone please help me ? I download the ''FlashTool (R&D Test Tool)'' but when i try to run UpTestEX.exe its close. What i make wrong ?

Traces of previous root?

I'm thinking about rooting my new LG G2 (D802 version). I read about 20 pages of this thread and used the search but I couldn't find a definite statement to what I'm asking myself, so please excuse me if it has been posted before. :angel:

Question: Can root on the D802 completely - I mean: without any trace - be undone using this method? Some people posted that after unroot there's a still a "rooted" line shown on the download mode screen.

Thank you very much, XDA! :good:
[G2 General] ollehhh:
I'm in the same boat too, it just errors out at 49% and I can't do anything.
[G2 General] J.Guido85:
Do we still need to find a key for flashtools? I read in here that as long as you change the date on your pc that you won't need a key is this correct?
[G2 General] J.Guido85:
Ok, So i've pretty much done everything on here and even followed the video on youtube and when i plug my att lg g2 back into download mode and flash tools starts, I get an error saying "Device model is different!" "Check phone or DLL!" "00000000"

I grabbed every file that was specifically for the att model, What should i do here?
[G2 General] J.Guido85:
This is the same problem i am having
[G2 General] J.Guido85:
Anyone have any idea?
[G2 General] SuperSport:
I read that if you flash a Custom ROM based of Stock that you should be able to finish the return to Stock. In other words, if you have an ATT G2, then flash something like CleanROM XE 2.0. This will place the Device Model back to Stock.

I personally have not tried it, I've just read it a couple times.
[G2 General] Demonlinx:
No, sprint uses the .tot file extension
[G2 General] SuperSport:
If you change the date, you still need a key. I've read that if you replace the MegaLock.dll file, you won't need a serial or need to change date. I guess the DLL file is not allowed to be discussed on these forums due to piracy issues, so I cannot go there. I guess you might try google?
[G2 General] DornoDiosMio:
I checked for a serial on google and one of the first links I went to I found an updated version of the flashing program that I used, didn't have to change the date, I found everything I needed there. I just searched for lgflashtools serial as it said to in the AT&T section of the first post.

I should note I'm on a D800 AT&T phone, but, I think the tool works for all LG phones. Check around to see.
[G2 General] SuperSport:
I'm currently using ver 1.8.1.1023, is that the latest?
[G2 General] J.Guido85:
I'll try this. Should I go back to 4.2.2?
[G2 General] TheSapient:
I can't find the Sprint firmware file. It does not appear to be on the Mirror, and the original link is 404.

[G2 General] RXG9:
Hi I'm using a LG G2 D801 (T-Mobile) with a custom recovery (TWRP 2.8.6.0), rooted, and CloudyG2 2.2.

If I use the KDZ method, it will flash to stock recovery (I will lose TWRP) is that correct?
[G2 General] hyelton:
Yes. But your best bet is to flash a stock based rom first, then flash back to stock.
[G2 General] RXG9:
Isin't Cloudy G2 a stock based rom?
[G2 General] hyelton:
Yes, but what I mean is without extra features etc as you may end up having to do the tot method.
[G2 General] scipion_s:
Hi, can someone please help me, is TOTing possible with the TWRP recovery installed, is Download moad still working? Also will TOTing remove the TWRP completely? Just in case I have LS980

[G2 General] cmmccaig:
Lg g2 trying to revert back to stock with kdz. Where do I put the files I have to download? Sd root, computer, also when I open 2nd screen on flash tool the screen is larger than my computer screen. Resolution is as high as it will go. Can't figure out how to fix it. Kdz rom I am downloading is also a text file and does not show up in flash tool as a .kdz file.
[G2 General] hyelton:
Huh? Everything needed and how to is in the OP. You choose the files in flash tool. And what 2nd screen? Its about the size of a 6 inch screen it's not that big unless you have the font on your computer turned way up. Also what text file? There's no text file.
[G2 General] cmmccaig:
When I go to the link to download the kdz file, once I download it, it has a .txt extension. Size is still 2.21GB. I will check font size. Don't think I checked that. 2nd screen...the screen that comes up after clicking cse
[G2 General] hyelton:
Maybe your browser doing it? Happens if you use internet explorer. Just rename it back to .kdz. Also that 2nd screen is about double the size of the 1st on. It's not that big.
[G2 General] ASoTosios:
huge problem at reboot

hello, i have problem on reboot, the phone still rooted and went into twrp mode...stuck here

Maybe your browser doing it? Happens if you use internet explorer. Just rename it back to .kdz. Also that 2nd screen is about double the size of the 1st on. It's not that big.

[G2 General] mathews95:
i was on stock - then flashed blisspop - cm12.1 - coludy 3.3 - now on dirty unicorn - i can't flash stock using kdz - stuck at 2% - is it because of cloudy rom - can i rectify this by installing stock based rom ??

then use kdz method if required
[G2 General] hyelton:
You could try. But if it doesn't work you'll need to do the tot method.
[G2 General] coinneach:
I'm not sure if I'm in the correct thread?

I updated to lollipop from kitkat and I now have the overheating, slow charging and extremely quick battery loss!!!

Also unable to get to the play store, you tube and gmail as well as various other apps.

I have the D802 and hardware version 1.0.

Android version 5.02

Baseband M8974A-AAAANAZM-1.0.190128

Kernel 3.4.0

Build number LRX22G

Software version V30a-AME-XX

I've gone through various threads today and I'm assuming AME in the software version is for the US market? I'm in the UK.

Could this be the reason for the problem?

If someone does have an answer could it be explained in extremely simple terms as I don't understand a lot of the terminology!!!

Many thanks.

Hey i need help, i've started flashing and get out from pc (at 60%) and now its 2% and lg mobile support tool showing me "upgrade stopped due to an error" Can i unplug phone? i think it get 100% and revert to 2 but i'm not sure :c help pls :c Ty
[G2 General] hyelton:
I'm assuming kdz method? If it finished then yeah unplug it. But if it didn't finish you may need to refash. You didn't really give any details of your model or if a custom rom or not.

LG G Flex Firmware Change

hello,

I have LG G Flex(Moden no.-LGF340L) and Firmware Version is Android 4.4.2. I want to change Firmware to Indian Version from Korean (F340L20g). Can i update firmware with Indian D8210C_00.KDZ ?

I am also confused about using LG Flash Tool - CDMA option ? As my phone is a GSM one. GSM is not listed in Flash Tool. Please help me.

Regards

[G2 General] C4SCA:
Always use cdma. About change the country version of ur rom, u have green flag to go do it. Just be sure the model number is the same.

For example i have a g2 d802, i can glash any firmware for d802 for UK as i well can flash european version for example
[G2 General] hyelton:
So are you sure you never changed your build prop , or running custom rom? Cause that error your getting reflects that.
[G2 General] hyelton:
First of all, no you cannot. Well you can but you'll be risking your device. No many people if any have tried unless there's a thread about it don't do it. Korean and Indian are two different model numbers. You almost most always want to stick to the same model.

Yes you keep it as cdma.. It has nothing to do with the cellular part of your phone.
[G2 General] hyelton:
Please Reread there post, there wanting to flash a different model and not the same. They have a Korean model which is a different model # than the Indian model.

[G2 General] hyelton:
There is your problem... Cloudy is not based on An LS980. It's based on a different model that's why your getting that error. You'll need flash a stock based rom meant for your model then flash back to stock OR use a hex editor and Edit the tot file.
[G2 General] makifaslan:
thanks

but how can ı do cloudy what based model

ı used hex editor edit tot file but I'm what write to hex

becouse cross if write to faile d801 to ls980 I edit to tot file d801

Do you now what based
[G2 General] hyelton:
I cannot flash it so I don't know. Probably based on D802. Why not flash a custom stock rom based on your model??
[G2 General] MaluNoPeleke:
What should I do if there is no connection to the PC in download mode?
[G2 General] hyelton:
What do you mean? How do you know there's no connection? Are you checking under com ports in device manager?
[G2 General] MaluNoPeleke:
No connection in the LG Flash Tool
[G2 General] hyelton:
As in? Are you getting network error? That's normal. You need to check your com ports in device manager to make sure it's there.
[G2 General] MaluNoPeleke:
I have tried different cables, driver versions and USB ports but every time I am in the download mode nothing is recognized at all, not even an unknown device or whatever and the LG tool cannot find a device. As soon as I am in the recovery or Android system the phone gets recognized by the pc correctly.

How to fix it? Thanks
[G2 General] hyelton:
But are you checking under commutation ports in device manager.??
[G2 General] MaluNoPeleke:
Yes, but it wasn't listed there while in download mode

Got ur problem..

Ur device is partially bricked so that some of the partition get corrupted.

First you have to fix ur partition by forcing it into 9006 or 9008 mode by shorting test point.

Then u have to use stock zvc or any version img or mbn file..after u will get download mode...and u will not get that unknown cross dll...

U are getting this error becaus you have erased or cirruoted your phone info...

Thats why its not recognizing..

I am a lg unbricker.......and it's a very common thing..

So dont ask me...how do you kniw??

Viaero D801

Hey,

I just bought a used like new D801 G2, and when it showed up it wasn't running stock T-mobile like I'd been expecting, but firmware from another carrier called Viaero. What I'm hoping to be able to do is flash it to a T-mobile stock rom but I don't know if that's a wise choice given that some earlier research turned up that some carrier's G2s (I think it was Claro) react very poorly to being flashed to T-mobile. Also, if I'm able to flash to T-mobile, can I just flash to whatever version of the ROM (That's T-Mobile and 32GB) or is there a specific one I should be using?

The case shows it's LG-D801, the hardware info in the About Phone section also shows LG-D801.

Android version is 4.2.2

Baseband version is M8974A-AAAANAZM-1.0.190034

Kernel version is 3.4.0

Build number is JDQ39B-D801-4.2.2-VIA-111113-1.7.0

Software version is D80110c

Thanks so much!

Edit: I gave up on waiting for an answer and just went for it. If anyone else comes across this with the same question, yes, you can just flash the latest (or at least 5.0.2 at the time I'm writing this) T-mobile ROM onto a Viaero 4.2.2 D801 with no problems. The LG Flash Tool (2014 version in my case) is very simple to use and it's near impossible to screw up if you follow diretions.
