Hi hyelton,

I will explain what I have done so far.

I bought my LG G2 32Gb [Said to be D802] from Ebay running on Kitkat 4.4.2. Every time I try for Check for software update I get error message - "Phone is not registered Yet".

So I wanted to flash Lollipop version manually. I have followed the instructions as specified in the first post of this thread.

I have used India D80230b KDZ file [Not sure if I can install this kdz] and installed the drivers.

I put the mobile in download mode [I saw the message that Download mode on the screen inaddition to Rooted message].

My Laptop [Windows 10] installed some drivers too. Everything is went smooth till 99% and message displayed that LG Flash tool is stopped working.

From then on My phone is bricked. I can only get LG logo and LED light blinking. Not getting switched off too.

Please help me how to proceed from here. When I tried to reset, I get the options to Factory reset [Volume down + Power button] but again going to LG logo even I waited for 30 mins. Now even my laptop is not detecting the download mode.

Additionally when I checked using my IMEI, imei.info says this phone model is D800 G2. :crying: :crying:

But other sites say it is D802. I am now confused a lot and doubt if I can get my phone back to working.. :crying: :crying:

Please suggest me if I can do the following options.

1. Do I need to Flash with D800 kdz / tot method [AT&T]. If yes, Can I use in India GSM 3G [Not CDMA]..?

If yes, Please suggest me how.

2. Is it any way possible to install D802 kdz..? If yes pls help me with instructions.

3. Can I install CM11 / 12 in my mobile which runs in India [GSM,3G not CDMA].

at this situation please help me how to go. I want to go with an option which will work for me without fail.

Thanks alot and save me.. :eek: :eek: :eek: :eek:
[G2 General] hyelton:
First of all when flashing anything after 85% means it's one.

2nd it might most likely be a D800. If it is follow the tot method which is also in the Op and use the D800 tot.

Your only real way of knowing is taking the phone apart.
[G2 General] SamsungIsBetterThanApple:
[MENTION=2607037]hyelton[/MENTION], thanks a bunch! It flashed perfectly, now I will try going to L.
[G2 General] tassos petrou:
Thank you hyelton.

I will try the tot method and will come back with the update.
[G2 General] KillerMOth:
TOT method

Hi, I applied a one click root+twrp. Something went wrong and soft bricked my phone.

It boot loops into twrp but twrp's gui is unresponsive. Have got it to factory reset in twrp get but i get "can't mount /data" in red text.I can get into download mode. TOT method kind of works. It runs through the process very fast and just says it skips all the partitions

Example of text COM41 box:

skip system partition

skip cache partition

and so on for all the partitions

the tot and dll files are fine cuz i used them to flash it earlier when i got stuck

I can't get the KDZ method to work. Does anyone know whats wrong
[G2 General] hyelton:
What's the error in flashtool?
[G2 General] KillerMOth:
It says

Skip aboot Partition

Skip rpm Partition

Skip boot Partition

Skip tz Partition

Skip misc Partition

Skip persist Partition

est... with all the partitions then its says 100% on phone and restarts
[G2 General] hyelton:
I've personally never seen that. That doesn't seem good.

Same problem for this guy
[G2 General] hyelton:
That's odd. Maybe a rom has caused this? It's happened before. Not that error but certain roms have caused issues.

Hi Guys,

I messed my phone twice and now my phone us not accepting fastboot commands, if I erase or flash any file it take ages and after that the errors comes some ting like "to many links open fail to..."

this is my current fastboot status

can any one please help how can i repair my fastboot ?

This is actually what's happening to my phone.

[G2 General] hyelton:
So wait why do you need fastboot? This method here requires download mode, not fastboot.
[G2 General] Jagankota:
I wish to install Lollipop CM11 / 12 in D800 as imagined.

At this situation, Is it possible? if yes, share me the link to the latest version.

I searched but couldn't find the suitable one.

Thanks.
[G2 General] hyelton:
What? This thread is for going back to stock using official firmware and methods. CM is not stock.

Just go to CM mods website. There are several of them in the dev section here as well. You have to root, flash twrp, then cm
[G2 General] Gamersab:
My phone was rooted before and then unrooted to unlock it ( by sprint I guess ) can I tot my phone ?
[G2 General] hyelton:
What do you mean can you tot your phone?

You mean flash back to stock? Yes.
[G2 General] ChazzMatt:
Just wanted to say thanks. Had two new D800 phones off eBay with 4.4.2. Rooted therm, then tried to downgrade bootloader to jelly bean in preparation for flashing a custom Lollipop ROM.

Something went wrong and neither would reboot. However, I could get into download mode.

This thread saved me. One of the phones was not mine. :)

I'm not a newbie. I've owned and flashed many Android phones (starting with LG Optimus M in 2011) as well as those for friends. But this LG G2, with the bootloader quirks has been the hardest. :)

But one D800 phone is now on Validus 5.1.1 and the other soon will be.

Thanks again for this resource.
[G2 General] aftabalam8c2:
Well i have seeen this issue.

Let me know which model?

And which stock rom version you r flashing?..

This happen when dues to many reason.

Like direct flashing of lollopop on jb....

Kindly let me know tge version u flashinh
[G2 General] Gamersab:
Okay thanks. Is there any easy way to unlock ZVE or ZVG ?
[G2 General] Gamersab:
And hey I got into download mode, I didn't flash tot file because it was written there at the bottom with red ' ROOTED ' what should I do ?

I checked via different methods all are saying that phone isn't rooted
[G2 General] getbacktoyourroots:
Which firmware?

Hey, I have a couple questions. Appreciate any advice.

So I'm on 4.2.2. stock VS980 with a custom recovery and I'm trying to flash a stock recovery to unroot and update to stock lollipop with a clean slate. Problem is, I'm on baseband VS98012B and the only firmwares for on here are 11A and 10B. Can I use one of these or are they actually totally different versions?

Also, I know you can't do an OTA with a custom recovery but can I flash the stock rom that I'm on with a custom recovery, or do I have to extract the recovery and flash that? If so is there any guides on that? Last thing is, will the TWRP version I'm on effect anything in the process? I'm still on 2.7.0.0 and was going to update it, but I'm not sure if it will effect my backup or flashing anything.
[G2 General] aftabalam8c2:
After returning to stock it still says rooted but its not.

Its normal.

If u want to change it to unrooted then flash jb and then flash kk

U will get rid of thie rooted red
[G2 General] Gamersab:
I'm Running zvd, can I flash tot over it ?

Will my phone remain unlocked ? If no, is there any way to unlock zvg ?
[G2 General] hyelton:
Rooted or not has nothing to do with this flashing process. Just because your not rooted now doesn't mean it wasn't before.

This guide wipes the rooted badge.
[G2 General] hyelton:
Wait what? You must use the method in the OP to go back to stock. You cannot flash them in recovery. Using the method in the OP brings everything back to stock.
[G2 General] aftabalam8c2:
Simply..

First root and unlock on zvc and then update through ota..

Hence u will not lose unlock
[G2 General] hyelton:
Yes you can, but what do you mean unlock? Like using the SIM card slot? Most likely whatever was done to use it would need to be done again. As it would probably "lock" that back.
[G2 General] Gamersab:
Yes Sim unlock but couldn't find any guide or tutorial for Lp ZvG :-/

---------- Post added at 02:20 PM ---------- Previous post was at 02:19 PM ----------

What if I unlock zve then take ota to zvg?
[G2 General] getbacktoyourroots:
Oh ok, from what I had read (possibly about just the OTA updates) I assumed you had to have a stock recovery before you could flash any kind of firmware. So I can just follow this guide and it will restore my stock 4.2.2 with custom recovery to everything stock? And how do you tell which firmware version to download for 4.2.2? I'm on 12B, but there's no download link for that one. Sorry, I'm so confused. Been searching all morning for this and cant figure it out.
[G2 General] hyelton:
You don't have to have stock recovery.. Everything you need to know is in the guide. Users actually use this to get back to stock recovery.

Not all firmwares can be available. I haven't kept up with the Verizon or Sprint model firmwares. It really doesn't matter what firmware you flash unless you want a specific one as you can always OTA update.
[G2 General] getbacktoyourroots:
I see, yeah I figured I was over complicating things, it's just so hard to find solid answers for this stuff with so many variables involved you know.. Just being extra careful to not brick it since I never flashed a rom. So thanks for clarifying! And I appreciate the tutorial!
[G2 General] hyelton:
Your welcome, and understood phones are not cheap :p

I'l try to get the kdz method working next week, have to study for engineering test for monday ;), would using tot vs kdz make a difference? .. Dont know what im doing wrong. but Ill mention you if I'm struggling again
[G2 General] Gamersab:
I flashed tot file for my phone and right now im on zve, problem is that my phone is locked again. I wanna take update too. Root unlock unroot then take ota or what ?
[G2 General] hyelton:
You can't take OTA while rooted, or well you shouldn't be able to.
[G2 General] Gamersab:
I asked some other people in other thread they said yes, what if I unroot afterwards? Then take ota.

Because I wanna taste lp so bad.

---------- Post added at 07:53 PM ---------- Previous post was at 07:35 PM ----------

Or take ota then root and unlock it ?
[G2 General] Soufiansky:
Sometimes it is possible but not recommended. I had a brick one time while i installed LP ota on my rooted G2. So flash it then root.
[G2 General] Gamersab:
Take ota then root ?

And which guide should I use to unlock ls980 for gsm ?
[G2 General] Soufiansky:
For unlock i don't know but i have seen a very easy way to do that on youtube. Just search for it you will find it quickly.
[G2 General] hyelton:
Well unlocking the sprint version is not simple as a normal gsm unlock. Id never recommend using a phone made for CDMA for use on GSM full time.
[G2 General] Gamersab:
So I took ota and rooted my phone successfully, now looking for reliable guide to unlock it :-p

Thanks for the help OP

LG G2 issue

Hello everybody.Today i bought lg g2 32gb from a guy who had rooted it and probably had installed wrong firmware and now i have only 16 gb.But that is not the issue i need help to.I tried countless times to root it with every possible option but nothing happened, i go to recovery ,adb..... but i have no root.I thought it might be the wrong firmware that guy flashed but when i try to change back to stock, then is where the issues begin.The guide of the 1st post gives me a message that servers are down and doesnt work.An other guide. With TOT isnt suitable for me as far. As i think because i have europian d802 with ONLY .kzd. if someone could give me a hand i would b3 gratefull.Im already at 7-10 hours and still nothing happeneds
[G2 General] hyelton:
The first method does work servers are not down, as there's no server for it to connect to lol, if you move that window you'll see it's actually flashing you ignore that message.

I'm getting the same error (Also on a Sprint LS980).

EDIT: It seems that restoring a stock rom backup fixed the issue. But what happens if you can't do that?

OR if you don't have a stock ROM back up like me! i'm going to try and do a factory reset and see what happens.

Hi guys,

I need your help.

I found two different files of the same FW version "D80210A_00".

File no.1. --> 1.22gb htt p://storagecow.eu/index.php?dir=Xda%2FLG+G2%2FStock%2FItaly+D802%2F

File no.2 ---> 1.92gb htt p://lg-phone-firmware.com/index.php?mod=Lg+G2&paese=ITA%2FITALY&id_mod=36

Which is the difference between the two files? The difference in tems of dimension is a lot... 1.92gb vs 1.22gb..!!! :confused:

Uninstall all previous LG drivers/ software etc.

Install the latest drivers

Facing hell lot of issues now and want to go back to stock with a clean flash. I downloaded the KDZ file for my model and tried to flash it using LG flash tool 2014 multiple times. Error pops up every time. Its either "upgrade stopped due to an error" or "connection to server failed". How do I resolve this? In addition to these problems, my navigation buttons are gone from an issue in my rom and cant use the phone now :crying:
[G2 General] hyelton:
The connect to server is not an issue, just move the window over and it's actually flashing.
[G2 General] hyelton:
That's still not the right one. You'll need to enable hidden ports in windows 8 to see the port.

Also don't even try USB 3.0 as it's not going to work at all.
[G2 General] hyelton:
What fails? At 2% if so you'll need to do the tot method then kdz method.
[G2 General] bigbadracer:
But its not.. I already read in a couple of places that it does but its not doing in mine :\

Thank you for the super quick reply
[G2 General] hyelton:
Then it's most likely due to the rom that was running before, you'll need to use the tot method then use kdz method to update.

Can anyone here help me with unlocking Zvg for gsm ?

Sorry I know it's off topic.
[G2 General] th3ant:
I know it's not the right one, that's why I posted! xD Still nothing even on USB2..

By Enabling hidden ports do you mean clicking "View" -> "Show Hidden Devices" in Windows Device Manager or do you mean something else?
[G2 General] hyelton:
Yeah that. It should show up a ports tab. Then you should see it as long as the phone is in download mode. If you still don't try a windows 7 computer. So many times people who have windows 8 cannot do this. Then they try it on 7 and it works without issue.
[G2 General] th3ant:
Awesome.. I'll have to locate myself a Win7 computer.. Will update if it's still not working.

Guys great post!. I live in Cyprus but I am not sure which rom to download. There are many Europe KDZs here http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/

[G2 General] hyelton:
You don't need adb to use this guide.
[G2 General] :
Technically no but the flashing fails at 2% with the WPARAM error.
[G2 General] hyelton:
Did you make sure C++ is updated and installed?

And made sure the com port is found under device manager?
[G2 General] :
While I have a vague idea how those are supposed to be done, everything is further complicated by the fact that I'm on windows 8, I should find a more technically inclined person and windows 7 PC. Many thanks for the prompt replies though.
[G2 General] oktheoriginal:
I quoted you to tell you about a error that occurs at 2% of the software upgrade. It only occurs in rooted devices. To fix you need to flash STOCK software using TOT method NOT KDZ!!!
[G2 General] hyelton:
Please don't quote the entire OP, You are sort of incorrect... Also I've already brought up to use the tot method in case of the error already. It's not new.

It occurs when your running a certain custom rom and or custom newer lollipop rom. I don't have a G2 at the moment to test this. But it has nothing to do with root, I have tested that. Just did one the other day it was rooted and running an older custom rom.
[G2 General] aftabalam8c2:
Oh dear.

You are a kid before hylton and me.

We have already mentioned the solution and troublshouting for this problem....

And kdz method can also be made to work instead this error.

Before posting such comment that reflects that you know more than the op....

Please go through all the comments.

I m not making taunt on you........

I have Lg G2 with CloudyG3 1.1 and I want to return to stock rom and unroot for OTA update. If I unroot with supersu it is ok? or what I make for unroot?. I bought this phone with root and now I want to update with OTA.
[G2 General] hyelton:
You'd need to go back to stock. Just uprooting won't allow you to ota. As you'll still have a custom recovery.
