And yes the "failed to connect to server" error was popping earlier but it was fine as the flashing process starts accordingly at main window. Now when connection error pops main window when reach at 2% show retry option.
[G2 General] diablob:
No, I stay on KK. BT made little drop out once per minutes on LP. Now its fine working phone. I tried only make new pairing with BT car stereo but not working.
[G2 General] hyelton:
Thats most likely due to the rom you are running/was running. You`ll need to do the tot method with the correct model, and then use the kdz method to update.
[G2 General] Bangash737:
What if i flash a stock kk or lp zip and wipe internal memory etc then try?
[G2 General] hyelton:
you can try, I don`t know never had issues
[G2 General] Bangash737:
Actually i got F320L korean version, can TOT method work on it? I feel like in the middle of the ocean :D, my guess in this case is to flash cloudy 2.2 with kk baseband and then try.
[G2 General] revan17:
I can't change the port because I don't see the phone in device manager while in download mode.

Yes, when I go to download mode I see download mode with 5 blue dots. Before, it would pass that and go to firmware update screen. Now it just sits there and nothing is shown in device manager.

I'm pretty sure the drivers are OK. They are the same I always use(from hyelton's site).

I'll try and flash a stock rom from TWRP. I already tried flashing Cloudy G2.2 but it didn't help. I'm now downloading this which should install stock 20H KDZ. It will remove root and TWRP but perhaps it will fix download mode.
[G2 General] revan17:
Nothing. Now it doesn't enter download mode at all, just goes to boot the OS. This is what my OS sees under device manager.

I changed the port to 41 but it's pretty much useless because when I hold vol up, it just boots normally. No download mode at all.
[G2 General] hyelton:
Thats what you want to see is the com port..

So when your phone is completly off your holding Vol up while plugging in a USB cable that is plugged into a USB 2.0 port and not a 3.0 port?
[G2 General] Soufiansky:
Use quick boot app , it needs root , and click on boot to download mode , hope it works.
[G2 General] revan17:
Success! Yeah, when I held the vol up button it just skipped to the LG boot logo. Weird.

I then loaded up the Flash Tool, loaded the dll and tot file and clicked the yellow arrow, without the phone connected, and waited a little. Then I connected the phone while holding the vol up button, it still booted the OS but the Flashtool recognized the phone and restarted it to download mode and went to the Firmware Update screen. After all finished, I flashed the 30D KDZ with the 2014 Flash Tool and I'm good.

Thanks all.
[G2 General] aftabalam8c2:
Its partially....bricked....

Its not in download mode as i told u before.

You have to flash stock flashabpe zip rom then you will get download mode with firmware update
[G2 General] hyelton:
Please read his above post ^^ he already fixed it.

Hey guys new to this thread and Ive searched quite a bit but SO MANY PAGES!!!

I upgraded to OTA Lollipop a few days ago. I just bricked my ATT D800 after installing TWRP which I think was meant for KitKat. I keep bootlooping to the LG "Security error" message...I can get into download mode and I am able to see the phone in the LG Mobile Support Tool except that it already tells me I'm on the latest software, so that tool is useless. I have installed LG Flash tool from the original post. I rooted the phone successfully prior to installing TWRP. Is it possible to re-flash the Lollipop OTA firmware? Possibly in a TOT file? I'm really just trying to preserve some pictures on the phone. Is it even possible?
[G2 General] hyelton:
Lg mobile support tool doesn't support any phone that usages the tot method ex:D800.

You'll need to flash what's in the OP. If lollipop was a available I wouldn't keep it to my self:p. There will prob never be anymore tots for the D800 other than what's available. You can flash what's in the Op and just OTA update.
[G2 General] polishfly:
If I flash whats in the OP do I lose my data? (assuming I dont bootloop and have to wipe)?
[G2 General] hyelton:
Yes. Tot method wipes everything. It's supposed to.
[G2 General] polishfly:
Any possible way to save the data before proceeding? (thank you for your quick responses!)
[G2 General] hyelton:
If you have no recovery or cannot boot into the phone, Its a very small chance and if so its not easy, I know its awful but not much can be done if nothing is backed up.
[G2 General] polishfly:
I have TWRP installed but I cant seem to boot into it...I have no recent backups, maybe from 6-9 months ago =/
[G2 General] hyelton:
You can mount your storage in twrp
[G2 General] polishfly:
Damn, I just wiped =( But either way I wasn't able to boot into TWRP...nothing I tried, and I literally spent about an hour holding the power button + vol down, letting go when the LG logo came up and then pressing again...I never got to the factory reset screen or recovery...I could only get into download mode using the vol up.
[G2 General] Gamersab:
Will I receive ota outside us ? Since I got sprint one.
[G2 General] hyelton:
Sadly no. You'd have to have it on Sprint service.
[G2 General] Gamersab:
Is there anyway to get lp ? Except custom ROM.
[G2 General] hyelton:
No official way. Unless your on Sprint and can OTA.
[G2 General] Andrei_fts:
Latest firmware?

What is the last firmware version i have 5.0.2 V30d on a D802.
[G2 General] hyelton:
That would depend on your country your phone is from.

But currently you have the latest as it gets.
[G2 General] IngMike:
Works like a charm, Thanks!
[G2 General] Gamersab:
What about sideloading update.zip ?
[G2 General] hyelton:
You might can try, if there's one over in the sprint forums. But it doesn't always work. I don't own a Sprint model.
[G2 General] Andrei_fts:
Thanks, i have the international version, do you happen to know if there is any custom rom based on this version?
[G2 General] SamsungIsBetterThanApple:
I own the LG G2 (T-Mobile D801) running KK. I want to upgrade to Lollipop but the OTA says I am up to date. I know for a fact (because I checked software info) I am not. I googled it and it says they have lollipop for this phone. So, I decided I would try a KDZ file. It was about to flash but then it said it couldn't and to try again. What is going on? I got the correct KDZ, I have the drivers installed, and my connection is fine.
[G2 General] hyelton:
What was the error? . If it said network error if you move the box you'll see that it is actually flashing.

Also make sure your putting your phone into download AND it shows up in device manager under ports.
[G2 General] hyelton:
Remember "International" can mean anywhere. What maybe international to you may not be for me. Ex: India would be international to me, while the USA wouldnt. And or vice versa.

Theres plenty of custom roms for the D802
[G2 General] SamsungIsBetterThanApple:
Thanks for the quick reply,

It just says there was an error; and yes, I did check to make sure it was connected.

EDIT: Let me expound on my reply. There was no box, it just said that there was an error and the bar disappeared and, in its place, it said to unplug, remove, battery, and try again.

I used to have the LG Optimus L90 and have used the flash tool many times, this has never happened to me.
[G2 General] cbarry05:
Hey guys its been a while since I have had to do anything regarding my G2 and I am a little rusty. I had to get a replacement from verzion and the replacement had Lollipop 39a baseband on it. I was looking to downgrade to the 26a kitkat baseband and am worried about bricking the phone. I saw a post earlier about just downloading the proper .kdz firmware and use the tool to flash. I just wanted to confirm that it wouldnt brick the phone (sorry for the newb question)
[G2 General] SamsungIsBetterThanApple:
Do a CSE flash and you should be all good. :good:
[G2 General] shezbot25:
Hi guys,

Tried to upgrade my ROM and bootstack and completely screwed up somewhere. Right now I cannot get my computer to detect my phone when plugged in, so no ADB access. The phone gets stuck at the LG Logo. I can't get into recovery (should have TWRP but may it got messed up?). I can get into download mode, where I see 5 blue dots. I think the biggest issue is that I can't get the phone to show up in Device Manager. I have the drivers from OP installed but no dice.

Any hints? Thanks~
[G2 General] hyelton:
So your looking under the ports tab under device manager for it?

Are you running windows 8 ? If so that would be your problem.
[G2 General] shezbot25:
Yes, the phone isn't listed there. I am running Windows 8.1, why would this be the issue? The phone would show up in Device Manager before I decided to upgrade as LG VS980.
[G2 General] hyelton:
Because windows 8 is know to cause all sorts of issues while flashing. I have that in the OP.

Did you make sure the port is not hidden in device manager? Windows 8 likes to hide them.
[G2 General] shezbot25:
Hey you're right! After enabling hidden devices I see something, QHSUSB_BULK. However, when I try to update the driver it doesn't seem to work :( It says that the device is not currently connected.
[G2 General] hyelton:
What do you see under ports?
[G2 General] shezbot25:
I see two entries for Standard Serial over Bluetooth Link (COM3 and COM4).
[G2 General] balajiik:
I bought from ebay as the seller says its a brand new, I tried flashing many D802 firmwares, even the one tracked using IMEI but now i suspect it as refurbished. Can you please let me know the next steps to make by mobile alive. Thanks in advance.
[G2 General] Gamersab:
I found update.zip over here on xda
[G2 General] hyelton:
And that's with your phone in download mode?

You sure it's plugged into a USB 2.0 port?
[G2 General] Mashed_Potatoes:
Nvm....got it to enter TWRP, had to press power 3 times very fast
[G2 General] shezbot25:
That's with my phone in download mode, and when it's stuck at the logo. Yes there are USB 2.0 or 3.0 ports. I only have two ports and I tried them both (my laptop is only a year old).
[G2 General] hyelton:
I don't think you understood eye I meant. USB 3.0 ports don't work at all with this. So no use in trying them. I'd suggest trying my another computer. Preferably a Windows7 machine
[G2 General] shezbot25:
Got it. I'm pretty sure I have one 3.0 and one 2.0 port. Either way, I tried my older XP laptop and it didn't detect the phone either. I tried my Linux machine too and that didn't work either :(
[G2 General] hyelton:
Well it's either a driver issue and or your phone is either a brick or semi brick.
[G2 General] SamsungIsBetterThanApple:
My phone is refurbished. Do you think this maybe why LG Flash Tool doesn't work?

Failed to connect to server

"failed to connect to server" error = Mine SOLVED

So finally i flashed the stock [MENTION=3276944]heyl[/MENTION]ton thanks for the tip. Here is my story :) (I am not a professional though ;) ) and may be you can further elaborate it.

Actually its simple , those who are running custom roms and wants to revert back to stock factory rom but unable to flash it, its because those rom may be build from different variants contains different kernals, bootystacks :p etc which leads to changes/disturbance in the your phone system. When i try flash tools 2014, it was giving me error right at the beginning "failed to connect to server" please retry. Then i try the old flash tools which is same as Flash tools 2014 and can be found on Lgviet.com and when i started flashing with old flashtool at software updater/upgrading screen it was showing me B100 and phone model D802(with its software version) where as mine is F320L, flashing started but when it reaches 49% it failed with an error "unable to find model". Luckily still the phone was working when i restart it. After that i decided to flash a factory rom (ZIP) using twrp and at first login there was no status bar, no navigation buttons :eek: . But phone was on actual build, with no recovery, root etc. Right after that i run again the Flashtool 2014 which show B93 (F320L V30D) and guess what it WERK :D without connection error.

This process is for those whose phones are in working condition.
[G2 General] hyelton:
The old flashtool is no where near recommended anymore. The files are still on my server if anyone wishes to use it but it's not recommended. Please read some of my statements. That error you said you had the network error, if you move that window over you'll see that it's actually really flashing.

But yes it is recommended that if you still have a working twrp and phone (remember not everyone does). But if they do flash a rom that's meant for there model then proceed to flash back to stock.
[G2 General] vpoejfas:
LG Flash Tool says the phone is disconnected.

A little backstory: in april I decided to install stock lollipop. I used LG Flash Tool and everything worked just fine. A few days ago I decided to give Resurrection Remix a shot. It required LP bootstack, so I installed that. I've been not so satisfied with it and decided to go back to stock. The problem my pc doesn't see the phone? When I try to boot into download mode, it doesn't seem to fully boot. I have 5 blue dots (https://cdn-images.xda-developers.com/direct/2/6/7/3/5/2/5/image2.png). LG Mobile Support Tool says the phone is disconnected and stops at 60% of "Analyzing phone setting". I'm not sure what causes this problem. Drivers are installed. In device manager my G2 is detected as Android Sooner Single ADB Interface. I have tried different ports and computers.
[G2 General] revan17:
I had the same issue. See my 2 posts about this.

Not sure if you understood me correctly. I do have download mode, my pc just doesn't see the phone. I'm confused. I don't have LGEModem under ports when I boot the phone into download mode. Although, I installed the drivers. After I clicked the yellow arrow and waited for LG FlashTools to do its stuff nothing happened.

This thread can get messy sometime. Ever I can get overwhelmed and either ask the same thing twice not know I had already asked etc. just so many people here haha.

Anyway for tot method to work you MUST. Change your lgemodem or LGE serial com port to com41 no matter what for it to work. No way around that. You didn't give much info, are you running windows 8 ? If so your com ports are hidden you will need to unhide them. Another reason I don't like windows 8.

Give that a go.
[G2 General] hyelton:
Did you not read the post fully? There flashtool is not working because they're computer either doesn't detect the phone OR it's just because they didn't change the com port because it's hidden. Either or they have to change that come port before the method there using would work. And in windows 8 (if there running it) they are hidden and the user has to unhide them to see them.

Also you did the kdz method. This person is using the tot method.

Now tried to install Lollipop Which bricked my mobile with LG logo and only LED blinking.

Please help me.

I'm running windows 8. My phone wasn't shown under ports when it was in download mode (not fully booted, with those 5 blue dots). When I turned it on it was shown as LGE AndroidNet USB Serial Port. I set it to com41.

Again, if I boot to this "semi-download mode" my pc won't see the phone. If I keep the phone on it'll give me an error USB Port Open FAIL.

Since I installed cloudy g2.2 I use another dll you provided. If that changes anything.

OH MY FLIP! I figured it out... sorta. My phone is not under the COM Ports. That is so weird. I thought it said it did but I was looking at my other phone... Darn.

I tried installing the drivers but to no avail. It says the drivers are already installed. So, I have no idea why my computer doesn't see my device in the COM Ports. I have it in Download Mode and my computer even makes a sound when it is plugged in.

Edit: Reboot fixed it. It sees my phone, but flash still doesn't work.

Hello all.

I am following the 1st method but i cannot complete the process. Please see the attachment.

I am doing what the message instructs but no luck... My G2 doesn't have a removable back so i tried with the volume down and power button instead. Maybe this is why?

I have soft bricked my phone (cannot boot to recovery) and i want to restore to stock (Europe_OPEN_D80220H_00.kdz). :crying:

I cannot solve it out and i would be gratefull if you could give me some advices... Thank you in advance.
[G2 General] hyelton:
So are you having problems getting into download mode? Or having problems flashing? You didn't really say., it seems you have flashtool already up, but you shouldn't do that til phone is in download mode.

Your phone should be in download mode for continuing on to flash/using flashtool..

If your having problems with getting download mode are you making sure the phone is completely off or (if you can't) using the reboot combo to restart it then using the download mode combo? (You can't expect it to go into download mode if your stuck at LG logo without rebooting)

Also make sure your using the cable that came with the phone and a USB 2 port and not a USB 3 port. USB 3.0 don't work and will cause the phone to not go into download mode.
[G2 General] hyelton:
Where you making sure you was using a USB 2.0 port? As USB 3.0 won't work with download mode. And will cause the phone to not go into download mode as well.

What's the full error? That seems like the phone was running something that was a different model than what your trying to flash.

Well first off all you need to be running windows 7 to fully not have issues with this. Windows 10 is not making things better..

Your post is confusing your not fully explaining what's going on, put the phone into download mode and follow the OP, everything in the OP are direct instructions.
[G2 General] hyelton:
What do you mean by flash still doesn't work? It can be anywhere from its actually flashing you just need to move the error to see, or an error somewhere else. Tot or kdz? I've seen your name before it's just today is a busy day of lots of posts.
[G2 General] hyelton:
I would had said do a factory reset. Maybe re flash? That firmware works fine no other complaints from others.
[G2 General] SamsungIsBetterThanApple:
KDZ, and yes, it is not flashing the KDZ. It stops and says there was an error and the flashing bar stops and the window gives me a set of instructions to try again.

I am able to go in download mode and this is the first step i do.

Then i am starting the flash tool and doing the steps as described in Method 1. The flashing seems to start but it stops with the message in the image i attached before. So the problem is on flashing...

My USB port is version 2. I am on Win XP SP3.

Any other idea?

No. Only kdz.

Follow the tot method by flashing what matches your model then do the kdz method to the file that matches country and etc.
[G2 General] tassos petrou:
I don't see a tot file that matching my model (D80220H-EUR-XX)... I checked in the link you provided in the TOT method, step 1.1 under the folder "D802 tot". Does this mean i cannot use the TOT method?

There's a few D802 tots.. Just choose the one that matches your size. 20h is the software version not the model.
