This is most probably your problem (in bold). And I'm wondering why you keep posting that the stock V21E has ghost calls when you have have installed a custom rom with a custom kernel. You've already made three posts in three different threads that V21E has ghost calls which clearly isn't true, at least in your case.

I suggest you could read before posting. Some relevant info here:

The creator of the Promethius, samno, said that "Ghost-calls problem is kernel related has always been. You shouldnt have any with stock kernel but if you flash a custom one you may be at risk until lg release there sources for 21E" (here).

Also another member, that didn't have any ghost calls with V21E, has noticed ghost calls immediately after he flashed the Promethius kernel. After he flashed back the stock kernel, the ghost calls disappeared (his post here)

Of course I'm not saying that at the moment the V21E has fixed 100% the ghost calls issue. My first ghost call with the 21A appeared 3 weeks after I installed it, so I guess we have to wait a couple of weeks. However, based on numerous reports here, people who were constantly experiencing ghost calls with the older GB roms don't have any GC so far with the V21E, so there is highly possible that the 21E completely fixed the issue or made it extremely rare.

Never had ghost call problem.

I have stock v21e installed on my o3d,and it has ghost calls.

I'll upload a screencapture later to show info about my device.

LG-P920H?

What kind of connectivity problems may I expect if I flash V21E on a Brazilian P920H?

I am currently using a downgraded Froyo to avoid Ghost Calls. I just can´t play with ROMs anymore. If I start having Ghost Calls again I may lose my job. If I decide to give a try on this ROM I will surelly do when I get my vacations.
[LG Optimus 3D] fsol:
In that case is better to wait 1-2 weeks.

We will keep in touch everybody abou V21E-i mean users like me which put already these rom.
[LG Optimus 3D] fsol:
Very strange... You can call to LG Italy and ask him about V21E. In some post i read in your country LG have good support about our problems with Ghost Call....
[LG Optimus 3D] botson71:
That's alarming. However:

@kekio84: You've said in the other thread you've started that also your battery drains very fast. This cannot happen especially when you came from Froyo. Any GB rom has much better battery life compared with any Froyo rom. Perhaps the .kdz you downloaded got corrupted? Or you didn't wipe before and after installing the 21E? I wrote a more detailed reply in your thread.

@Claudio67: Did you update with the official LG tools/method or the unofficial offline KDZ method? Also, did you wipe before and after installing the 21E? And did you install any custom rom/kernel above 21E?
[LG Optimus 3D] Claudio67:
I've used this and this. Stock rooted, deodexed and zipaligned with dsixda kitchen. Downgrading now to froyo anyway this is my last LG product.
[LG Optimus 3D] lw_wl:
sorry, i just saw your question. since the ghost call issue was solved, i don't come back here that much.~O(∩o∩)O~

i don't use 1080p recording usually, because 1080p record is too dark on O3D, it can only be use on the outdoor.

to answer that, i just test the 1080p recording, on 2 vid, both 60 seconds. all smooth, no freezing for one second.

and after that, free memory is 166mb.

i'm using sslauncher1.5.7 ,it saves much more memory.
[LG Optimus 3D] deleeros:
I think that LG is using us as beta testers for her new firmware update... That's great...
[LG Optimus 3D] lw_wl:
you'd better wait for a couple more weeks.
[LG Optimus 3D] kekio84:
I ididn't wipe before installing the new rom through kdz method,but i did a factory reset after that. And a day after,i had 1 gc.(maybe even more,but i don't know) and the battery drain was huge. Then,yesterday i went into cwm,and wiped everything,except battery stats. It works better so far. I don't have gc by far and the battery is workin much better. My battery is still around 65% after more than 12 hours. We'll see in a few days. Will keep reporting....
[LG Optimus 3D] botson71:
Correct me if I'm wrong but a stock that is "rooted, deodexed and zipaligned" is not exactly a "stock" anymore, is it?

This is my last LG product too but since I'm stuck with it at the moment, I'm trying to do the best out of it.

So far, many people have reported no ghost calls with the real stock V21E and only four reported ghost calls. All those four reports were claiming that "V21E has ghost calls" but after we've asked:

-the first has flashed only the 21E besaband, not the complete rom.

-the second has flashed a custom rom/kernel above the 21E.

-the third has reported a worse battery life than Froyo.

-the fourth has deodexed and zipaligned the stock rom.

So actually, none of the above had the stock rom, with the exception of the third report where clearly something went wrong because none of GB roms has worse battery than Froyo.

I'm sorry if I'm a little agitated but we're all in the same boat here. And reports that claim that "the V21E stock has ghost calls" while clearly they are not referring to the stock but a modified rom/kernel, are not really helpful.
[LG Optimus 3D] Claudio67:
Well mate if you want to consider "deodex and zipalign" as the reason of ghost calls no problem for me.
[LG Optimus 3D] kekio84:
I am the thitd one. But my rom is realy stock. Not deodexed,zipalinged,nor custom rom,or kernel or anything. I just didn't wipe my froyo with cwm before installing v21e. After i installed v21e,i did a simple factory reset. A day after,had a gc. When i noticed that,i wiped everithing through cwm(except battery stats) and my phone seems to work now fine. If a get another gc,i'll let you know. Battery is great so far. 48% after almost 15 hours. And the rom seems faster now than after installing it.
[LG Optimus 3D] douglam:
Take it easy man. We are all frustrated about this GC issue but I think there is only so much that one can do to sort out the misleading information. Appreciate your efforts but there is just too many things can go wrong here with so many ROMs and kernels available. On top of that, everyone here has different technical skill levels.

Maybe it will be easier if you start another thread similar to

http://xdaforums.com/showthread.php?t=1655327&page=1

And state your requirements there (post only if fully stock condition)

Besides, we've been living with this GC issue for many months now. I don't see it can get any worse than this. And I believe that you have a feeling the v21e is definitely the best solution at this moment.
[LG Optimus 3D] libertine99:
appearently I had GC too

v21e,

custom rom, based on v21e, but no custom kernel (promethius)

on it for 3 days,

had at least one GC today :(
[LG Optimus 3D] botson71:
I don't want to consider anything. I just asked you if a stock rom which has been rooted, deodexed and zipaligned could be considered as a clean rom or a modified one.

Perhaps the deodexing and zipaligning is not the reason of the ghost calls but can we be 100% sure that it's not?

No problem but perhaps you didn't fully understand my previous message. I was not talking about the "many ROMs and kernels available", but just the one and latest V21E rom which apparently (according to numerous reports here) fixes the ghost calls.

There isn't any need to start another thread because I don't want to weaken this one here. And I don't have any requirements, apart from the obvious: when someone states that the new "V21E has ghost calls" it would be very helpful for the rest of us if he also states if he's referring to a clean V21E firmware, or a modified V21E.

So far, from the four people that have only said "V21E has ghost calls", after the rest of us have asked for a clarification, it was revealed that only one (@kekio84) has a clean V21E. The other three have either installed only the 21E baseband or modified the 21E with custom kernels/roms or by deodexing and zipaligning.

Also, please don't get me wrong. I'm the last person who will say that 21E is 100% ghost-call free. When the 21E was released, a few days later many people have started reporting that it is "100% ghost-call free". I was one of the very few who said that we can't be certain before some weeks pass w/o ghost calls. And still I'm not 100% sure that the V21E solves the issue. I'll have to wait a couple more weeks to say that.

You've added this after I posted my message. Actually the only feeling I have about the V21E is that the battery life has been improved and the battery stats are fixed. I'm not sure at all if the ghost-calls are fixed as many others claim. I'll have to wait at least a couple more weeks to be certain about that.
[LG Optimus 3D] kekio84:
Well,as i said before and in the other thread,i wiped everything through cwm yesterday(except battery stats) and everything works fine. And the battery is great so far and no signs of gc so far either....
[LG Optimus 3D] wayno140:
Yeah cause they know half of us already voided our warranty

[LG Optimus 3D] pandaball:
Your warranty isn't voided if you root or flash custom roms... You can always revert it to stock and they would be none the wiser.
[LG Optimus 3D] wayno140:
Yeah I know thought about it after I posted it

sent from my acidhazard thrill
[LG Optimus 3D] douglam:
Yeah, only time will tell if the v21e has solved or at least reduced the GC occurrence. But I was saying that there might still be a lot of misleading feedback of the performance of v21e due to the availability of custom roms and kernels. If there is NO custom rom or kernels available, there will be less "noise" introduced to complicate the issue because we would all have to use the stock v21e as is.

And now we found out that the phone behaves differently if the user did a wipe or not, even if it's all stock. So again, another potential for misleading feedback.

Let's continue to monitor the situation. Take it easy :)
[LG Optimus 3D] cyclonmaster:
I believe any ROM v21E + stock v21E kernel solve the issues. If the mod kernel being used, GC problem will be back again. So better stick with stock kernel atm. I've been using Promethius ROM v21E + stock kernel v21E with no problem. It's been 3 weeks now, so far so good.
[LG Optimus 3D] botson71:
Yes, that's the common experience so far. If you use any other kernel than the v21E you'll have ghost calls no matter if it's a custom kernel or a stock kernel from previous GB versions. When LG will release the V21E kernel sources, then it would be also possible to build custom kernels w/o the ghost-call bug, as samno said.

However, one member has reported ghost calls with the stock v21E rom and kernel that has been rooted, deodexed and zipaligned. Is there any possibility that those procedures could again bring back the ghost-call bug? If there isn't, perhaps the v21E stock rom/kernel is not 100% ghost-call free.
[LG Optimus 3D] superage:
I was planning to upgrade my O3D to V21E but when I checked last week from LG Mobile Support Tools. The latest update for my O3D European Open still V21A.

I may upgrade to V21E Italy using manual method but I will not do it.

As of now, I never experience a single ghost call (except I force it with the method I found).

I have run RRC protocol trace (decode all L3 layer radio messages) on my number and found every procedure was executed well by O3D.

I decided to wait for ICS and wont upgrade my O3D to any newer GB stock if any.

I hope you guys can find a way to make yourself feel better with your O3D, for me, I am very satisfied with my O3D in any aspects.

I am working as radio network consultant and the hidden menu on the LG phone is really helpful for me. My favorite menu: 3845#*920# then select Modem Settings then Engineering Mode. I really love it.

V21A --> V21E and no single ghost call/sms in 10 days.

Damn!! Finally my girlfriend don´t bash me to the lowest hell

coz now I get every sms and calls from her.

Hopefully it stay like this and everything else works well too,

video, 3D, network, bluetooth handsfree....

With V21A I used to have gc/sms something like 2-4 days in week.

but got one internal recognizing something, during that i made a call to the o3d, and didnt got the gc . └(^o^)┘
[LG Optimus 3D] dreccon:
One week on v21e. Yesterday the phone froze while exchanging files over bluetooth. While it was frozen, it got ghost calls. I had to remove the battery to bring it back to life.
[LG Optimus 3D] vicdo1000:
V21e

Been having ghost call issues for several months now....and just got into the habit of dialling the home number every 1 or 2 hours to see if I was still on the network. If the phone connects, then im good, but if the phone hangs up immediately after hitting dial, then i knew the network had dropped off.

Not uncommon to drop out 1 -2 times a day.

Flashed v21e Italy yesterday (kdz) (to get v21e baseband) before flashing CM7 RC2 over it. Had 1 instance of GC today still.

Just downloaded GetRil and realised my RIL was on V21a whilst baseband was v21e.

Updated RIL now....will see if the matching RIL and baseband will get rid of GC.

Otherwise, will try stock V21e ROM (be it painfully slow compared to CM7) and see how it goes....
[LG Optimus 3D] kekio84:
Hmmm..... O.o Strange thing is that i downloaded GetRIL and it showed that i have LGP920-v21e-apr-19-2012 baseband. And it says that the recomended one isLGP920AT-00-V21E-apr19-2012. I installed through kdz method.
[LG Optimus 3D] vicdo1000:
V21e baseband and RIL (Radio Interface Layer)

OK, so having updated the RIL to v21e to match baseband, i still had 1 instance of GC today.

Looks as though v21e is on GC proof when:

- Have the stock rom

- Have the stock baseband

- Have the stock Kernel (since my Kernel is based on CM7 RC2 ROM flash)

Going to try Prometheus v1.3 tonight and see if there is any luck with being GC proof...
[LG Optimus 3D] dreccon:
It has been posted several times before. The fix is in the kernel. Any kernel not based on v21e will cause you ghost calls.
[LG Optimus 3D] vicdo1000:
First full day on Promethius v1.3...

No Ghost Calls!

This has been the first time in over 3-4 months where there are no known GC instances :p
[LG Optimus 3D] lw_wl:
ware you using go launcher? i found out it is not much compatible

with bluetooth. it cant be switch on or off after the phone runing for several hours. but the sslauncher woundnt have this problem.

if you dont like sslauncher,

maybe you just leave the bluetooth on, its not much different to the battery life.
[LG Optimus 3D] dreccon:
@ lw _ wl

Thank you but I'm using Nemus launcher. It's easier on memory than Go launcher. I was thinking of Touchwiz 4.5 too but Nemus is enough for me right now.
[LG Optimus 3D] Araltd:
Promethius 1.4/1.4+ = NO GHOST CALLS?????

So are people using Promethius 1.4 and 1.4+ kernel and having NO GHOST CALL issues?
[LG Optimus 3D] yourguitarist:
Yes sir. They're both based off of v21e and its proven to be ghost call free
[LG Optimus 3D] botson71:
I have the V21E for a month now (it was installed on 4th May) and I can most definitely say that the ghost calls issue is over.

Except of the ghost calls fix, LG has probably made additional optimizations on this ROM. The V21E is definitely more fast and snappy, and with better RAM management than the V21A and V21D I had before. This also resulted to a better battery life. :)
[LG Optimus 3D] dreccon:
3rd week on v21e and I must say things are running as expected. It looks like we can forget about ghost calls. I bet we'll be back with new and unexplored issues when the ICS update comes out (in 2020 I estimate)!!!
[LG Optimus 3D] linuxluver:
I have an LG Optimus 3D. I have Gingerbread on it. I have had the ghost call on two telcos (New Zealand): Telecom and Vodafone.

But the third telco works just fine (2Degrees). They use Huawei telco gear while the other two telcos do not.

Summary: My Optimus 3G works perfectly on 2Degrees but I get ghost calls on the other two.

So what did I do? I bought an LG 3D Max. It works perfectly.

I really like the 3D phone...and I'm not going to throw the whole idea away because of what appears to be a mismatch with telco gear. I'll roll the original Optimus 3D back to Froyo. That worked really well.

v21e baseband fixs GC issue
[LG Optimus 3D] damonous:
I'm a little late to this thread, and it's good to see that there appears to be a firmware update which appears to completely solve the problem. However, using the original 2.3 firmware, I've been fine except under the conditions described below. For anyone hesitant to do a firmware upgrade, this may help (I'm thinking there could be other types of BT devices that also 'interfere')....

Check what bluetooth items you have connected to your LG. I've had the P925 (US ATT Thrill) running the 2.3 update via manual flash since about Jan 2012. I've noticed that certain bluetooth watches can demonstrably cause the 'ghost call/text' issue. I've seen it with WimmOne and certain MetaWatch firmwares, but not when using Sony MBW-150 or LG Prada Link.

In my situation, the above was repeatable: I could connect the devices in question listed above and experience the 'ghost' problem; then disconnect them and have my P925 run just fine.
[LG Optimus 3D] Stinger2U:
I've been using the Prometheus rom with v21e kernel, and after a couple of weeks the ghost call problem appeared again. Damn you LG.

Hello guys, the V20B version have ghost calls ? it is the latest official rom from Cosmote (Greece)

so far i didnt had any problem...

and it is sure tha all P920's owner had ghost calls with Gingerbread ?

thanks.....
[LG Optimus 3D] dreccon:
The version you just mentioned is supposed to have ghost calls but not every single device will suffer. Still, if you run into trouble, you can take your phone to LG service and ask them to upgrade it to v21e. This way you will not void your warranty. That's what I did. :)
[LG Optimus 3D] Unabomber1:
Unfortunately i have lost the proof of purchase so i cant go to LG service to upgrade my p920..... :(
[LG Optimus 3D] dreccon:
Well, then you can leave it as it is since you said you didn't have ghost calls, or you can upgrade it yourself. You will find instructions on page 9 (if I remember well) of this thread.
[LG Optimus 3D] Unabomber1:
with 21e do you have any ghost calls ?

i might try to update it my own.....
[LG Optimus 3D] dreccon:
No ghost calls with v21e. The problem is fixed.
[LG Optimus 3D] Unabomber1:
finally i updated to 21e...................... :)

after i update it need to get a full wipe or not ?
[LG Optimus 3D] dreccon:
If you MUST preserve your previous setup, the full wipe is not obligatory. Still, you'll be on the safer side if you do it and you must definitely do it if you feel things are not working the way they should.
[LG Optimus 3D] Unabomber1:
Thanks...... i fully wiped because i have little lags with my wifi..... and now it is super..... :good:
[LG Optimus 3D] dreccon:
Hopefully this thread will soon be rendered obsolete. The deadline for the ICS update has passed and there is word on LG Singapore facebook page about it ( https://www.facebook.com/LGMobileSingapore/posts/10151098010297707 ). My only hope is that we won't have ghosts of any kind this time.
[LG Optimus 3D] sol-invictus:
after reading the hole thread and using CyanogenMod 7.2 stable with baseband V21e for some weeks now i still get ghostcalls with bad battery life if the baseband crashed...

is there any solution in using CM7.2 and a stock kernel? if yes, how to do this? :)
[LG Optimus 3D] dreccon:
I suggest you use your CM7 on a Froyo baseband and wait for ICS to be released (hopefully before the end of the year). With official ICS ready, CM9 won't be far.

Read on: http://sevencolourgossips.wordpress...um-coming-it-will-be-much-more-than-only-ics/
[LG Optimus 3D] sol-invictus:
thank you for your answer, but i was comming from a Frodo baseband, when i first installed CM7 - resulting in having no network connection at all... after some searching i found this:

wiki. cyanogenmod. com /wiki /User:Porcoesphino

so it is mandatory for cm7 to work that you have installed a gingerbread baseband v20a or above!
[LG Optimus 3D] dreccon:
Oops! Sorry! I guess I had previous versions of CM in mind that (as far as I heard) worked with both basebands. Well, then you're right, you need to use a kernel based on v21e which is compatible with your ROM, but I can't help you here. I want my 3D functions, so I'm using stock v21e. Good luck! Please post your results if you find a solution for everyone to know. Thank you for bringing this up!
[LG Optimus 3D] sol-invictus:
I think the first version the P920 was supported is CM7.2.0-RC1 according to the cyanogenmod wiki - maybe the dependency for a v2xx baseband was introduced afterwards...

ok, i will keep you updated on that issue! when in 2g mode the GC issue happens not that often...
