Well, I used your method...

...and it worked fine, managed to flash 4.4.2 EU open .kdz on my HK d802 that came with 4.2.2 and all seems good.

I've also just rooted using ioroot25 and that also went well.

Now I'm just wondering which camera mod to use, I would really like the auto focus to be quicker, it takes an aaaage for the picture to be taken using the stock camera...

Thanks for all the help hyelton!
[G2 General] RobHands:
OP maybe you should stickie this.

I did everything manually according to this post (http://xdaforums.com/showpost.php?p=50991830&postcount=25)

The only time it worked flashing a old KDZ!

That is already in the OP.... Under method 2.

download not working

Hey there hyelton, I'm trying to download one of your .kdz (the 80210b 32GB HK) one and it's not quite going... Any ideas.

Actually, scrap that, it's downloading fine.

Is there anything I should think about when going back to 4.2.2 from 4.4.2 I was thinking of using your normal .kdz flashing guide, that should work right?
[G2 General] Xsoldier2000:
trying to TOT back to stock, have the drivers installed and in Download mode, but step 10 is where I'm getting confused. I'm new to WIndows (linux user since XP came out) how do I make sure my port is set to COM 41 in Device manager? Took a screenshot of where I'm at, but right clicking on my LGE Android Phone under Other Devices doesn't allow me a COM choice.

What am I missing?

(Maybe I'm better off going the KDZ route.)
[G2 General] hyelton:
In the screenshot it shows the drivers for the phone are not installed so kdz method or tot won't work til you install drivers. If you installed them try to reinstall them and restart your computer.

After restarting did you change your com port to 41? And unplug the phone and plug it back in?
[G2 General] bhratashri:

Thank for the quick reply.

My port was already set to COM41 in the device manager before the install.

I did unplug and replug after I got ready on the LG Flash tool. I did not unplug and plug after the installation.

TOT Method, changed port to Com41 but not recognizing in LG Flash tool

any thoughts?

I thought there were other settings that needed to be changed in the advanced section of the device manager to get the phone to be recognized in LG Flash
[G2 General] hyelton:
After changing your com port be sure your unplugging your phone and rerebooting back into download mode.
[G2 General] hyelton:
The only thing that needed to be changed is the COM port to 41
[G2 General] JoeProcopio:
does LG Flash show anything in the Com41 window that the device is connected? I get Downloading DLL, then Failed PreviousLoad error...maybe file is corrupt, i'll try a new download

---------- Post added at 12:58 PM ---------- Previous post was at 12:57 PM ----------

reconnected to TOT file, and it seems to be working ATM...I'll post if we're good!
[G2 General] hyelton:
use a download manager when you try to download a again, But a bad download might not cause it to say it cant find the phone though.
[G2 General] JoeProcopio:
thanks...that seems to be the answer, just reconnecting the TOT file, looks like the path was different (even though it is the exact file) anyways, it's reloading now...we'll see what happens....thanks for the guide and help....

BTW, the KDZ method didn't work for me, the B2C app would not install on my laptop. (I'm running bootcamp on a Mac though, Win7 Pro 64...maybe it doesn't like Mac hardware,lol).

So we're booted up, LG Flash says PASS! let's boot it up
[G2 General] hyelton:
Awesome glad it worked!

HELP... Stuck in reboot

I flashed 4.2.2 .kdz from being in 4.4.2 (phone was rooted using iroot25) and my D802 is now stuck in reboot mode... What do I do?

I managed to get the phone into download mode and started the .kdz flash (HK 80210b) again and it is flashing... I just hope it wont go into reboot loop again...

Hmm, flashed the .kdz again, finished ok but same problem, it's stuck in a reboot loop... So now I'm trying to flash the same 4.4.2 .kdz I had before the downgrade

Ok, so I now managed to flash in the 4.4.2 .kdz I had upgraded to and now the phone boots normally... But how do I go back to 4.2.2 which the phone had when I got it? Do I need to unroot first perhaps?

-----------------------------------------------------------------------------------------------------------------------------------------------------------

I finally got my D802 working again (flashing using the .kdz method) after coming back from 4.4.2 -> 4.2.2

I just had to do a reset as phone was stuck in boot loop.

I do have a different problem....

I can't enable 4G, I could when the phone first arrived with 4.2.2 but since upgrading to 4.4.2 that option is gone, I am now back to 4.2.2 HongKong (the original ROM my D802 came with) and I can't enable the 4G option any more...

The 3845#*802# method only last until a reboot, so does the *#*#4636*#*# method and of course I only have the GSM/WCDMA option in the "Mobile Networks" menu

! have 2 of these G2 units and the other one is completely untouched and that one works fine, 4G is there and all.

I'm worried that something must have happened when I rooted using ioroot25 (EFS is backed up) or when I flashed the .kdz to upgrade to 4.4.2 (OPEN EUROPE) ?

Flashing back to 4.2.2 (HongKong) using .kdz method went fine, the device information say I have exactly the same Android version, Baseband and Build and all as my untouched G2 but still the untouched G2 has 4G option and some Chineese bloatware installed, I did not get these bloatware back when I flashed back the 4.2.2 (HongKong) .kdz

Any ideas?

USB Port Open FAIL

When the install is at the "Waiting for the 120 sec reset", should the phone reboot or not?

If so, should it reboot to download mode or in the setup?

During this reboot, should I disconnect the USB cable?

At the 120sec you mean after it flashed correct? It should reboot on its on to your phone..
[G2 General] bhratashri:

OK. So everything till there works fine. Phone reboots. But after that it just gives this message saying USB port open fail! Is there something I am supposed to do after the reboot?
[G2 General] hyelton:
Once the phone reboots when flashed its done any errors on the computer just mean it lost connection when it restarted.
[G2 General] StreetkillnHD:
could u answer this question

should i be worried?
[G2 General] shingers5:

Why would you use that Method? TOT method is RARELY used. Just use the Method from the First post?

Also that link is the ONLY one out there so just gotta wait on that one if you must have it that way.
[G2 General] daddioj:
if u must know :p im playing around with the AT&T phone. and I prefer the tot method anyways. much more stable
[G2 General] hyelton:
lol, Yes the TOT is more stable. BUT unless the model matches the EXACT Same as the tot you downloaded in the build prop the TOT method wont work. Like the software currently on your phone much match the exact version/model as the TOT or it will fail. KDZ`s on the other hand don`t care, but the TOT`s do.
[G2 General] daddioj:
well I tried converting with KDZ just t see and it fails half way through flashing

[G2 General] cacciucco:
I can only tell you that a G2 with HK software will not have LTE when used in Europe with an European Sim, I had the same problem. It will never work unless you flash an EUR kdz. I bought my phone (unknowingly) from an HK retailer of the Internet and it arrived sealed with HK software without LTE option. I flashed a EUR 4.2.2 kdz and LTE started working. I then received the KK update via LG update tool but that put me back on HK software and lost LTE. I then flashed 4.4.2 EUR kdz and LTE started working again. It should be noted that updates received from LG are based on your IMEI number, LG will always take you back to the software of the region associated with your IMEI number no matter what you may have flashed on your phone.

I have the same problem. I was back on 4.2.2, and the rooted mesage is gone. After updating to 4.4.2 I was rooted again.:confused::confused:

On, 4.4.2 ,just root and then put 2 rct files into Persist folders then set permission power off device and check download mode status, then trn on yor phone, go to superuser app and unroot. Go in download mode again and see yor status.
[G2 General] guvno:
I'm having different results

I got 2 G2 units, both from HK, the one I flashed with a EURO .kdz has lost it's 4G option (It was there before but since I updated to EURO 4.4.2 ROM it's gone)

The other G2 unit is completely untouched, and it's running the original 4.2.2 HK ROM and it has 4G! I have tried the same SIM in both units!

I am now trying to get my 4G option back on the G2 which I updated to EURO 4.4.2 and I simply can't... I have downgraded to the original 4.2.2 HK ROM and according to the "About Device" menu, both units are running EXACTLY the same SW, everything matches, but still there is no 4G option on the G2 unit that I flashed. I'm now going to try and restore my EFS as I did do a backup with ioroot25 and got my 2 .img files, but I need to find out how to restore...
[G2 General] AlexeyOD:
thanks for all! Good wokr.
[G2 General] hyelton:
Restoring EFS won't do anything. Its all software as to why its not there. If it was an EFS problem you wouldn't have service or really bad service. Just because the software version matches doesn't mean its the same. I can have a UK branded D802 and a branded D802 from another country and it will have the same software version but things like the LTE things might be different

Every time I click on normal web upgrade nothing happens, it just opens up the lg support tool or whatever it is and says an upgrade is available... Am I supposed to go to the options menu and do recovery upgrade? I don't want to mess my phone up. The kdz way worked fine before but not it won't do anything. Stock Rooted 4.2.2 d803
[G2 General] guvno:
@ hyelton

Hmm, I was afraid someone might say that... So you thing that the EFS only contains RF parameters, IMEI and stuff like that? No flag or setting towards whether 4G is enabled or not ?

I understand that some phone units can have the same SW but then still have different features like LTE, that's why I would have thought there are parameters controlling this which I would have hoped would be in the EFS? Otherwise usually there is a "customization SW" that differs units apart but again, that would then be visible in the "About Device" menu, some of the information there would be different.

I have 2 LG G2 units, both bought at the same time, both from HK, both hare now running JB 4.2.2 ROM (HongKong version) both are flashed with the .kdz file (Hong Kong 32GB D80210B_00.kdz) that you host.

And yet, the G2 unit that I played around with by updating it to 4.4.2 (EURO) has now lost it's 4G setting, also, there are other differences between them I have now noticed, even though I have done a full factory reset, several times. The unit that was not upgraded is playing the "life is good" tune upon start-up, the other one is not, one has some Chinese bloatware, the other one has not...

I can only imagine that the G2 unit I played around with by upgrading it to 4.4.2 somehow got messed up and going back to 4.2.2 is not helping. That's why I think it must be some parameters or something...
[G2 General] guvno:
Well, looks like restoring EFS did not help anything...

...just as you said...

I just don't get it then... I am back on the same 4.2.2 HongKong ROM that I had before, and yet my 4G option is gone...

The other G2, running exactly the same 4.2.2 HongKong ROM does have the 4G option... As mentioned, there are other differences

as well, it play the "life is good" tune every time it starts, also it has all those Chinese bloatware, but the G2 that I flashed with 4.4.2 EURO ROM and now back to 4.2.2 HongKong ROM is not the same... I guess there must be some customization software as well which has disappeared from this G2 unit...

There's not one. Only the 16GB version is available in the Netherlands
[G2 General] ayup:
Hey guys, I'm a lurker for a long time and what not but I have two questions:

1. Is it necessary to go all the way back to 4.2.2 if you "screw up"? Can you just flash the KitKat tot and have everything be unrooted?

2. If you are using the lgflashtool and you are on AT&T and you are in download mode, all set up, everything in place and it's stuck at ready and don't know what to do, the thing that I kind of figured out is if you unplug the usb and plug it back in when it says "ready" starts up. Don't ask me why, and I'm sure that's probably not the safest thing to do, but I've had to do this twice now because I thought I was really screwed with this phone and reflashing to stock.

YMMV but that's what I did and it's worked twice (going on three times now -_-)
[G2 General] :
Ok so I cant use the TOT method because i cant put the phone on debugging mode.My only option is KDZ but no matter what I do I get the vbs script host error.I ve tried several things but they just dont work...I am on windows 8.Any ideas on that?Any solutions?:confused:

[G2 General] db4z:
I'm getting the same error from LG Flash tool using the tot method "failed previous load()". I'm also not getting the expected milky way error and I never see a "ready" message I think should be appearing. It seems like lg flash tools is not detecting my phone, despite it showing up correctly in device manager and set to COM41.

I've also tried the KDZ method several times and it acts like it does something and completes with no errors, but my phone never does anything on the download mode (firmware update) screen while it is supposedly being updated. The progresss bar never goes above 0%, so I'm guessing it's not really doing anything.

I've spent hours starting over and going step by step through both methods but nothing ever seems to get transfered to the phone. I am on verizon, rooted with stock pre-OTA rom with no major issues, and just want to unroot so I can apply the OTA upgrade to stock kitkat. I also have all anti-virus software disable and performed a factor reset on my phone.

Appreciate any help. Thanks.
[G2 General] hyelton:
When you say you never see the ready thing. Did you click the yellow arrow??
[G2 General] db4z:
Yes, then it runs through some processes and about 30 seconds later i just get a popup error with "failed previousload()". After hitting ok nothing happens.
[G2 General] hyelton:
Did you download the tot file via a download manager or try uninstalling and reinstalling everything? Right now this error is computer based seems like

Never mind, got it to work. Maybe I'm just tired but for some reason it wasn't clear to me I had to start in usb debug mode and then reboot into download mode from the guide. I was in download mode the entire time. Thanks for the replies.
