[LG Optimus 3D] superage:
It may be also related with Kernel. To be honest, am not so sure.

I have open the baseband file and I could understand some information from there and Yes, it is having important information about how the phone react with the cellular network.

Until now, I never experiencing a single ghost call except I force it myself with the method I found and am having my O3D running with stock rom V21A.

You also can do some tests and you can prepare a note.

When you are working in the office. Select Network Mode GSM/3G auto.

Open Dialer and press *#*#4636#*#* then open phone information.

There you can see the cell information, "Location", note the "CID" and check this "CID" every 3 minutes and you can do this test for 30 minutes.

If you have different CID in 30 minutes. Your phone may do cell reselections and this will make our O3D to perform handovers when you are about to receive or make outgoing call.

You also can try to select 2G or 3G only at your office. This will eliminate RAT changes.

Then give it for a week to see the result.

Have you try to follow the method I found to produce a ghost call ?

How about the network mode you set ? Is it GSM/3G auto, or 2G only or 3G only ?

Please keep posted and I hope this ghost call issue resolved with V21E, someone reported ghost call also exist with V21E, but we need him to reconfirm again.

V21E already released for Italy. Can we check if there is V21E for Open Europe ?
[LG Optimus 3D] testina:
I never had trouble GC with original rom, zip, KDZ, but two times with titan kernel 0.4.2 v21d.

Replaced kernel and now go smoothly.

The phone I bought it just came out on the market and with all the changes made ​​this was the only case.

So for me it probably depends a lot from gc kernel.
[LG Optimus 3D] vpamir:
Just for your information, the V20G baseband doesn't work with V20D (the latest official rom released in Turkey). I'm flashing V21E from Italy now...
[LG Optimus 3D] linusmax:
Hi testina, we are in same country. the kernel is for me the direct or indirect cause of the problem, in any case is connected with the solution. With 21E also for me now are 48 hours widthout any gost call, and my phone work, 48 call in only one day and 36 sms in 50km. For me ghost call is END. I have received SMS in real time for all two day, with the previous release I received sms from time to time and I had to reboot the phone three or four times a day to see how many calls I was losing . This 21E is perfect. Now i have ask to LG Italia in Italian Forum if it is possible know where is the gost call problem (in baseband, in kernel or in firmware). Lg Italia turns the question on the internal reply and for all the own comunity. If LG reply, i write in this threed.

---------- Post added at 08:43 PM ---------- Previous post was at 08:32 PM ----------

Ok I can reply to you also now because i have do this test in the first day of ghost call problem.

1) I work in area where 3G is very poor. Only near the doors arrive 3G signal with high db value. Inside the office is dotted with numerous changes from 2G and 3G network and reach different cells.

2) If i switch in 2G mode the problems are reduced but there are always ghost call

3) First of 21E, with 21D i solved with BlueKernel 1.09 (Korean Kernel) no wipe no reinstall any software on my O3D.

Bye
[LG Optimus 3D] dromico:
I'm using Auto mode
[LG Optimus 3D] superage:
Thanks. :) I have a strong feeling, O3D will have a ghost call when failed to follow the complete procedure of RAT changes and cell reselection. If O3D covered with good network quality, it seems to have less or no ghost call and when covered in poor coverage, then Yes, probably will have lot of ghost calls. The fix coming with V20G or V21E will probably eliminate the issue by fixing the RAT changes/cell reselection procedures when O3D covered in poor coverage.

What I do believe, if they do change with the baseband, they may also have to change the firmware. Whatever it is, the new firmware released by LG hopefully will solve it. I think I will upgrade my O3D soon. :)

---------- Post added at 11:10 PM ---------- Previous post was at 11:08 PM ----------

You already have V21E with you, so let us wait and see. :) If you keep auto mode, that would be good for the tests. Let us check again after a week.
[LG Optimus 3D] dromico:
I think there are some trouble in firmware versions...

What I understand is:

Some weeks ago LG released a firmware in germany ( v21d )for the ghostcall issue, but in some case ghost call occure with this firmware too, then few days ago LG put out 2 version, v20g asian rom, and v21e europe rom ( date 19-apr-2012), lg italy says that 21e solve ghost call, there are no change logs on 20g.

In this sort of soap opera of firmwares it's not easy to survive, and numbers lg use don't help O_o

Then if someone want to try I suggest v21e not 20g
[LG Optimus 3D] vpamir:
only those who can endure the stress and agony of all those rom versions, basebands, kdz flashing tools and **** are worthy of using the mighty Optimus 3D.

We must consider ourselves the chosen ones.

LOL.
[LG Optimus 3D] sandulea:
I tried your method many times but it didn't produce a ghost call on v21e. I also have a deep basement in which I test very poor signal conditions, so bad that it fails to receive at least half of the test calls. 2g, 3g, auto, but no GC. Only the 3d button reboot will cause a ghost call for me now, as far as I can tell.
[LG Optimus 3D] V1P3R_BR4Z1L14N:
It seems you didn't own a motorola milestone, my dear friend ;)
[LG Optimus 3D] ©ZEUS®™:
Wrong alarm. Mine is v20e from Turkey, not v20g. These frakking version numbers confused me. My mistake.
[LG Optimus 3D] dreccon:
I'm freaking out! I called LG Service to tell them how I caused a ghost call using superage's 2G-3G method. They told me theu couldn't file a fault report since I "tricked" the phone into producing the fault!!! So they just told me that this kind of behaviour is (for them) acceptable. They will file a report only if the ghost call happens by itself...
[LG Optimus 3D] linusmax:
I can confirm to you V.21E have solved problem of ghost call. I use 21E from friday, until today all call is perfect and no ghost call. You can upgrade :-)

Now is very very important know as LG have solved......for developer custom release. There is also first custom kernel and firmware that use V.21E release as based, but Kernel is no V21E based and use old Spanish Ghost Call free reduction.

For me is absurd to produce custom kernel, groping in the dark

Bye
[LG Optimus 3D] modecom:
That's nice, but IMHO three days is too short a period of time to prove ghost calls are history; let's wait and see

I keep my fingers crossed as I've been planning to buy LG 3D but this ghost call issue deters me
[LG Optimus 3D] cool_recep:
V20E Italy, so far so good.
[LG Optimus 3D] superage:
Perhaps my post on the other thread did not attract you.

Is there any one can confirm that V21E, free from problem below:

1. Phone reboot when pressing 3D button.

2. Screen freeze for 1-2 seconds while recording video 1080p (in every 10 seconds).

Or just confirm, V21E just okay for everything. :) I would upgrade my O3D soon once you guys confirm it.
[LG Optimus 3D] samno:
@superage everything seems fine for me on 21E phone will only restart on 3d button if you have removed 3d space otherwise its fine ;)
[LG Optimus 3D] sandulea:
It'll only reboot if you uninstalled the 3D Space app. If you still have it then it just launches the app when you longpress the 3d button. It's solvable anyway, you can make it launch any other app. I personally don't know how to do this, and I uninstalled 3D Space, so I'll try not to accidentally press the button too often:p

Oops, just saw samno beat me to it
[LG Optimus 3D] superage:
Thanks, @sandulea @samno.

I will schedule to upgrade my O3D to V21E tomorrow night. :)
[LG Optimus 3D] xstokerx:
so you guys are saying that v21e fixes this cuz i have never had ghosted calls or msgs tell yesterday and today and rogers just told me to do a battery pull witch did fix it for a small amount of time but then it returns ill have to try 21e if this keeps up.
[LG Optimus 3D] dromico:
after some days I found that battery life is good, I use my phone ( now I can call it phone... ) with bluetooth and wifi always on, ghost call never happen in these days, we have to wait and check
[LG Optimus 3D] Optimus3Drocks:
We can finelly say that gc have gone

For.me i bought the o3d before two weeks and iam still working on foryo rooted

And checking here every day finelly i can upgrade

Q >> is the v21e relesed in meddle east

And on my stock rom i cant find ota update >> why ??
[LG Optimus 3D] cool_recep:
Battery life is so far the best. This ROM (V21E Italy) not only fixes ghost call, but also have a very good battery performance.
[LG Optimus 3D] zeljkobo12:
I agree, three days on 21E, no ghost call. I really hope it's gonna stay like that.
[LG Optimus 3D] lw_wl:

48 hours on v21e italy now!

i am loving this phone again!

\(^o^)/

everything is smooth!

no lag!└(^o^)┘

( on sslauncher 1.7)

edit: its v21e,not 20e ╮(╯_╰)╭
[LG Optimus 3D] alexandru.m:
Thank you for the information, one small question, since you are also from Romania : is the update available on the lg updater, or can it only be installed by flashing the KDZ on the phone? I reverted to froyo using the kdz method, but it was a big PITA changing the hosts file, and setting up the server etc..
[LG Optimus 3D] dromico:
21e is released for openmarket phone, then for sure branded phones never "see" the update, kdz is the best way I think
[LG Optimus 3D] johny-b:
so since the release of 21E no gc anymore everything is working pretty smoth, so now the o3D is finally a phone again, after nearly 6 months. To bad that because of the whole gc problems and the waiting for the fix and that not knowing even now that is not sure that is fixed, I ordered a HTC One S, my second phone (first Omnia 7) that i bought because of the gc problem. So thank you LG for that. It only cost me about 800€.
[LG Optimus 3D] alexandru.m:
Mine is not branded , at least not that I'm aware of .. it is an unlocked phone , I purchased it without a contract. I'll wait a few more days , maybe I'll upgrade in the weekend , but I'll try the updater tool first , just in case.

Thanks for the info!
[LG Optimus 3D] dreccon:
I just checked the lg update tool and it says the latest version for Europe open is v21a. Perhaps this v21e is Italy open??
[LG Optimus 3D] carllord1974:
phone fixed - or so i hope.

I too have been suffering with the ghost call issue after upgrading to gb. After a lengthy conversation on the phone with lg technical support, to which i may add that they denied all knowledge of the ghost call issue, i returned my T-MOBILE branded phone for repair.

After 4 days recieved my phone back with a letter advising me that my pcb had been replaced as it was beyond repair. My phone is now an unbranded o3d running gb v20a. As i have only had the phone back for 3 days i havent yet missed any calls and am recieving all my texts so far. I will post if anything changes though. Good luck to anyone who is still suffering from ghost calls. My advice is to send it back.

My Lg optimus 3d is once again a phone and no longer a gimmicky game console.
[LG Optimus 3D] nspn80:
How about video recording? I have freezing on every 10 sec...
[LG Optimus 3D] paulharrison123:
Mines working finally, first full day I have had without the GC issue / reorganising internal ever - finally a decent phone!!! WOOO
[LG Optimus 3D] sandulea:
Alexandru.m: unfortunately I have one of those "not for sale" models. It won't upgrade via LG software or over the air because it's not detected correctly, so I don't know if this version is available for update here. I always flashed manually, and I recommend you do the same. If i remember correctly, a few phones got bricked when updated via official methods when the GB update rolled out. Apparently, with LG life's good if you do it yourself :p .
[LG Optimus 3D] abo_mara7:
New firmware for Middle East:

http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP920/AAREML/V20f_00/V20F_00.kdz
[LG Optimus 3D] botson71:
Yes, it's the Italy open not the Europe open version. The download path is "csmg.lgmobile.com:9002/swdata/WEBSW/LGP920/AITAML/V21e_00/V21E_00.kdz" and the bold letters indicate it's the Italian version.

Another easier way than the LG update tool, to check which version is the current for your O3D is by following the link below (just change the XXXX with your IMEI number):

http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=XXXX
[LG Optimus 3D] JastaPein:
just got my brand new O3D which is still under Froyo 2.2.2 (V10d 7/8/11 Philippines) and im wondering what GB version should i get that doesnt have any GC Issue.. .

Update OTA or Update via PC Suite?
[LG Optimus 3D] botson71:
The only two versions that don't have ghost calls is the V20G (Chinese) and the V21E (Italian).

It's mostly not possible to update OTA, only through a PC. But the official LG update tools will only update to thr GB versions currently available for your phone/country. So if you want to update to the GC-free versions above you need to do it with the unofficial methods (posted on the dev section here).
[LG Optimus 3D] JastaPein:
@botson

is it a BUG FREE versions of ROM'? links for that method would be much appreciated :)
[LG Optimus 3D] dreccon:
My advice is to wait for about a month to verify that v21e is ghost call free and then upgrade to that.

I don't know about OTA. It doesn't seem to work for me.
[LG Optimus 3D] xstokerx:
just flashed 21e see how it works out
[LG Optimus 3D] vpamir:
god, when will it stop?!?

:confused:
[LG Optimus 3D] cheong12001:
I think the content of the firmware is the same and oringinally from 20g which issued by beijing china but local restricted. I have compare the baseband files with an extension of fls among 20g and 21e, they actually possess the same file size!!!
[LG Optimus 3D] docentore:
comparing file size wont tell you anythng. do md5sum or crc compare
[LG Optimus 3D] ceffisi:
one week with new 20e (Italian) without any issue of ghost call or ghost sms.

Battery's life now is nice!

Since 9 in the morning to midnight with data, WiFi and Bluetooth always on, and normal usage

Hopefully I start to have nice android device, now!

:-)
[LG Optimus 3D] cyclonmaster:
I certainly sure new v21E fix the ghost call issue. I'm using Promethius ROM right now with stock kernel. Smooth and no problem at all. Everything is working fine.
[LG Optimus 3D] alexandru.m:
Just updated to v21E using the oficial updater, my phone is recognized as Germany based, so it seems the update was released in more countries than just Italy. Hope that ghost calls are a thing of the past now.

Edit : I was just trying some test calls while playing some game and after closing the game .. calls went through, but when I went into contacts, I got the USIM loading completed message, I know I read somewhere in this topic that the message is a symptom of ghost calls, but the call went through 2 seconds before that. Should I be worried?
[LG Optimus 3D] ©ZEUS®™:
I'm in Turkey. Should I flash middle eastern V20F or Italian V21E?
[LG Optimus 3D] adixtra:
I think it is the same. But i recomended v21e :). New germany v21e - is the same as italian.

The tool app show me:

Country: Portugal

and

"Start Updating"

Does This means that the new firmware is availble to my country and I can realy update from LG server?

now I have installed GB official rom v. 21a Nov-15-2011
[LG Optimus 3D] dreccon:
v21e is available for Greece open. Going to upgrade later tonight.
[LG Optimus 3D] Bender303:
I would do a factory data reset to make sure, the update keeps all apps and settings but there might still be ghosts in the machine ;)
[LG Optimus 3D] alexandru.m:
I just tested out a theory : if I stop the contacts application (which might have happened to free ram for the game i was running) and call the o3d from another phone, calling works, but the caller name does not appear immediately, and when you go to contacts, you get the USIM loaded message. So it seems it was not in "ghost mode" :D, instead , the USIM loaded message appears when the contacts app is loaded (most of the time it will be already running in the background).
[LG Optimus 3D] dreccon:
I can't upgrade using the upgrade tool even though v21e is available for Greece. I tried the link above with my phone's IMEI and got this result:

"csmg.lgmobile.com:9002/swdata/WEBSW/LGP920/ACSMML/V20A_00/V20A_00.kdz"

This is the latest firmware for the network of COSMOTE. The strange thing is that my mainboard has been replaced twice by LG service, so it is supposed to be an open one and not locked to a certain network!

It looks like they just take ghost mainboards, wipe and reflash them and swap them among unsuspecting users telling them they gave them a new mainboard!!!

Great trick to fool customers and buy time. Way to go LG!
[LG Optimus 3D] pandaball:
Uh, I think you've got it wrong. When they replace mainboards they will replace it with a similar one, ie it will still be under whichever carrier you're using, so the IMEI number will still reflect that you're using Cosmote. Or, you're using the original IMEI given at the factory which is locked to Cosmote.
[LG Optimus 3D] xbsall:
Tried with my IMEI only to check.. works just fine greek v21e.

O3d bought from vodafone greece once upon a time.

Btw since chinese V20G didnt have any ghost calls.

I think its time to try V21E and see what happens although my little Sony NeoV has official ICS..
[LG Optimus 3D] dreccon:
You may have a point, but my original mainboard was Europe Open and they never asked me which network I'm using. Moreover, both times I sent the phone to service I did a full wipe and factory reset, so they couldn't possibly see any data. So, how did they decide to give me a mainboard locked to Cosmote? I think my previous point still stands...
[LG Optimus 3D] carllord1974:
Update!

Well its been over a week now and still no sign of the ghost call issue. I finally have a phone that works. Phone seems to respond well, battery lasting all day and no sign of the "re-organising internal processes" before a call.

:D
[LG Optimus 3D] sak500:
Havn't had GC in over a month on V20G germany ;)

[LG Optimus 3D] brightboy:
There is gc on v21e:(. I just have this.
[LG Optimus 3D] botson71:
Of course your point stands. You've purchased a Greece Open phone, that's why when you brought it to service they installed the V21A which the correct ROM for a Greece Open phone. If you had a Cosmote phone they would have installed the V20A instead.

The first time you've updated your phone by yourself from Froyo to GB, did you get the V21A or the V20A? If you got the V21A, then they've certainly messed up at the LG service and I suggest you contact them to sort it out.

Could you give more details? Did you upgrade to the full V21E or just the baseband? Are you using now the stock V21E with the stock kernel or you've upgraded to custom ones? And did you update to V21E with the official LG Tools/methods or you flashed it with the unofficial methods? If you flashed with the second method did you wipe everything before?
[LG Optimus 3D] dromico:
Same experience for me, no problem until now with 21e ( installed from kdz because my phone is vodafone italy , and the latest VF ROM has Ghost call problem ).

Use of the phone is better then 2.2 Rom in my opinion ( latest rom Acura 2.2 ), in the last days happen to me two types of problem, one a crash of the phone during a call, phone in call but can't switch on the screen, after one minute or two I can see the screen, with the call active, then I switch off and on the phone, and all goes right, the other one is while calling, I selected the number then touch the call button, the screen show the call function but immediately became red and close ( maybe is only a strange reaction to line busy, but I can't see the busy message ).

never happen "reorganize etc" message, and no feedback of ghost call .

I don't know if the two problem are related to ghost call and the actual rom can manage these error without crash or other type of error related to a particular condition of the network.
[LG Optimus 3D] dreccon:
Actually, my phone was EURO-OPEN, not GREECE. The first time I upgraded, it went to v21a (naturally). I would understand if the Greek service gave me a GREECE-OPEN as they might not have a supply of EURO-OPEN mainboards, but to give me a COSMOTE mainboard with v21a installed is beyond my comprehension.

Anyway, I have contacted LG Customer Support and they are going to take my phone in (for the third time) via their own courier to unlock and upgrade it. I hope I'll have it back by the end of the week.

One thing is beyond any doubt in my mind: My next phone will be either a Samsung or a Sony!!!

V21E

Hello guys, from 4 days i have isntaled clear V21E and i don't have ghost call!

I put a lot of programs (viber,skype etc..) and they works perfect.

Also i don't have already masaage"please wait,phone reorganizise internel process" (something like that i thing i read on my phone with previous version)

I thing we have already worked 2.3.5 version for our phones;)
[LG Optimus 3D] paulharrison123:
Phone has been flawless since flashing 21e - no ghost calls for over a week, battery life massively improved, I finally have a phone!!!!!
[LG Optimus 3D] dreccon:
This is all very encouraging but let's not rush into conclusions. I've had my mainboard twice replaced. The first time it took a month to have the first ghost call and the second time it took three weeks. Both times the firmware was v21a which is considered to be the worst in terms of ghost behaviour. I won't be sure about v21e before I have tested it for a full month.

Brightboy has reported a few posts back that he had a ghost call with v21e. I guess we're all waiting to hear a few more details from him.

@brightboy

As botson71 asked:

1) Did you flash the baseband only or the full kdz?

2) Did you use official or unofficial flashing method?

3) Did you root?

4) Are you using the stock or a custom ROM?

5) Are you using a custom kernel?

6) Did you do a full wipe after flashing v21e?
[LG Optimus 3D] douglam:
Yes, at this point in time, it's still too early to tell. But based on limited feedback and personal tests, I think the v21e is the best among all the previous versions.

BTW, using custom ROMs using non v21e kernels may potentially cause GC problems too.
[LG Optimus 3D] brightboy:
1) Did you flash the baseband only or the full kdz? FULL KDZ

2) Did you use official or unofficial flashing method? kdz_fw_upd_en
