Hi,
I have a strange problem. I am unable to make calls from my P990. If i try to make calls with UMTS active my phone does nothing. It is unable to call or get called from anybody. SMS do NOT work most of the time.
In GSM mode i can send and receive SMS messages and receive calls. But i can not make a call. It rings but when the called person answers the call my phone just ends it.
I think this problem can not be ROM based, because i switched from multiple CM10 nightlys to the leaked ICS by tonyp and harsh a few days ago and the problem is still there. While i changed the rom i did every wipe i could find, cache, davlic cache, internal sd and factory reset and fixed permissions as well.
Before switching to the leaked ICS rom i tried different (at least five) basebands to overcome the in call audio bug (loud strange noise on the called persons side) which worked for a few days, but then started to develop this problem. With the leaked ICS rom i tried both the P990_V28E_00_CP.fls and P990_V28G_00_CP.fls from tonyp's download site.
Can anyone think of a way to solve this really annoying problem?
If you need more informaion, like log files, build numbers, etc. please let me know what exactly and i will try to provide them to you.
Thank you for your help.

I tried this today, same problem here.
Something i forgot to mention is that when i try to call somebody and it does not connect i have to force quit the connection to the mobile network to end the call attempt from the phone. So i have to either switch in to airplane mode, deactivate the mobile network or switch from gsm to umts or the other way around.
If i do not do this the phone will try to place the call as long as possible with no result.
Do you think i should try and go to stock froyo and see if the problem persists?
u can try to nvflash the stock rom.it'll be clean then.
i-ve had the similar problem with leak ics rom.
my sim was over 10 years old and after changing the card problem was solved.
my telecom gaved me newer one with the same number.

I flashed the stock (2.3.4) rom (kdz version) with AIO-P990-ToolKit_v1.1-fixed which uses the official LG flash tool after making sure to have the gingerbread partition layout.
So now i have an old system V20Q_00.kdz with Baseband version 1035.21_20110725 but i am still unable to make any calls.
I will try to match baseband and ril next, but if this does not work i have no idea what else to try.
Anyone else?
Thanks.
OK, didn't work either.
Next try is the rom and the baseband from here http://forum.xda-developers.com/showthread.php?t=1504280.
ROM: Gueste2X "GoodBye" v2.0R
Baseband: v20l, 1035.21_20110725
Sms work without any problems, but the main problem remains. Calls, last about 3 seconds. Regardless wether the called person answers the call or not.
Calls to me are working perfect. Checked my APN settings and they are find to.
Is there any logfile i should provide to help track this problem down?
Any hints, suggestions ?
Thank you.

Well now it becomes really strange.
I tried a different sim card a few days ago. Same problem. Unable to call anybody. Today i tried it with yet another sim card. Calls worked perfect.
The only difference between the sim cards is the following. My original sim card is from bob (virtual provider from A1) and the first sim which did not work is from A1. So technically they are from the same provider. The one which worked is from a different provider (telering).
What adds to my confusion is the fact, that my sim card works perfectly in another P990 without any problem.
So somehow the combination of my P990 and sim cards from A1 and its virtual provider bob do not work. They send me a new sim card during the next week. If it works i'm happy and can finally make calls again.
If not i will change provider. :crying:

I did have this problem before.
All things are good except my original SIMS.
And solved by resetting the IMEI.

Wow. This worked. Thank you so much.
With smartflash i activated the option to Erase CAL data and reset my IMEI back to my original one.
Now all my call issues are gone. I hope it stays this way.
Thanks again.
I have a Nubia Z9 mini (Indian Version) - nx511j
I have put two SIM cards in my phone and the phone is having 4G/3G/2G mode in one SIM slot and 2G only in the other. (4G mode can be enabled in either of the slots)
My problem is when I enable 4G/3G/2G mode in one SIM slot the other is not connecting to 2G.
2G networks are shown listed but unable to connect
So at a time only one SIM is working in the phone
I have tried changing ROMs but no help

i tried every option in *#*#4636#*#* nothing change

no one can help
After flashing my K50 T3s, first with Cyanogenmod 13 (unofficial). there were no SIMs found and no IMEI.
Then I flashed with S433_StockRom_BySmiLeToLiFe_TurkDevs
This recovered the SIMs along with the orignial IMEI.
But now SIM2 only works on 2G. SIM1 works fine on 4G.
Any ideas?
I found the answer. You have to activate data for Sim 2. Then it works on 4G.
But I didn't have this problem on the earlier system on this phone.
My xperia xz3 (SOV39) doesnt want to be connected to any network, the SIM card is detected but the signal bar is empty (and internet doesnt work too).
I already tried several SIM card by another providers but still doesn't works.
Please help me ???
