420 gave me the noise issue. Trying V30a baseband ATM. This far it works flawless. Made 5 calls. Will report back later as it seems the problems doesn't appear directly.

Edit: Still no problems, battery seems fine except for wifi. 5h and counting.

Edit2: This is for sweden, carrier Telia.
[LG Optimus 2x] Raphyo:
Hi everybody,

I just tried :

420 (su660) : no audio while making call (it always did this on my phone with su660 bb).

725 v20l : work, but having battery drains.

521 : work, with probably less battery drains than 725 v20l.

I'll stick with 521 for now.
[LG Optimus 2x] goodmamba:
Hi all!

I had a few hours battle with my O2X and in the end it happened! Superb battery life (better than GB).

1. Install BB 0521-V20s (I live in Europe and this one is the latest European BB. Have tried SU bb and older EU bb and v20s has the best battery life and signal)

2. Instal a fresh CM10 (full wipe)

3. Install Gapps

4. With "Root uninstaller" from Gplay delete Talk, default Browser (install Chrome first) and some wallpapers (I also deleted Trebuchet after installed AWD launcher as I like AWD more)

5. In Settings/Wifi/Advanced uncheck "Network notification"; on "Keep wifi on during sleep" choose "Only when plugged in", Wifi idle timeout: 5min, On "wifi region code" choose the right one.

6. Settings/Display/Brightness choose the lowest value visible and after that install Display brightness (free on Gplay) app by RubberBigPepper in which setup a default 20% brightness. Always avoid "Automatic brightness" as it actually consumes more juice than a Manual setting.

DON'T CHANGE YOUR DEFAULT RIL!

Care to say how;
[LG Optimus 2x] SLS197:
Hi,

have you thought about setting up your phone from the scratch?

I started flashing my phone with the kdz method.

Because I have read in some threads that people are facing problems after using the

smartflash method.

I did the following:

1) flashed stock recovery

2) KDZ flashing method using V20s.kdz. I set the phone manually in download mode.

3) Installed CWM 5.0.2.8

4) Full factory reset. Dalvik Cache wipe. Format /system.

5) Flashed CM10 via CWM

6) Boot and finished first set up.

7) I had the constant vibrating bug and "high" battery drain as well.

Changed Wifi settings--> advanced--> changed to disable in standby.

8) The battery drain, I think is not real, its because the battery is not calibrated.

So I deleted the battery stats with CWM and fixed permissions (suggestion from other user).

Rebooted and just load and unload the battery several times.

9) Still had the "vibration bug". I installed CWM app from market and updated to 6.0.1.5

--> vibration bug is gone, long press power button works!

(suggested from other users)

10) I did not change the RIL. Although Getril doesn't know RIL. Don't care!

So, this worked for me. I have no call audio issues so far.

Location: Germany

Carrier: Vodafone

Maybe this also works for you?
[LG Optimus 2x] mike the mighty viking:
First, thank you for this tutorial, it is sofar the best in humble opinion!

Secondly I can only stress: DONT CHANGE THE DEFAULT RIL!!!!

Thirdly, if none of the non SU660 bb works with your phone, the one I have had great succes with, is in KASHAMALAGAs post in this thread:

http://xdaforums.com/showthread.php?t=1658047&page=34

It is the SU660 V30c and since I installed it, no radio problems, the RIL this wonderful CM10 comes with is developed for the SU660 bb. Also there are no problems with network time.
[LG Optimus 2x] daas88:
The cm10's default baseband and ril looks like it had been made for my region (Venezuela) because network works perfectly for me.

Even better than with the baseband I used in cm7, the 725.

Sent from my LG optimus 2x with cm10 :)
[LG Optimus 2x] Vankata_91:
Which app you used to make CWM to version 6.0.1.5, because i tried rom manager and i didn't succeed?
[LG Optimus 2x] Ajsh:
Why should we not use su660 BBs? You say it in a way that makes it sound negative. Please explain:)
[LG Optimus 2x] mike the mighty viking:
Not negative at all. Previously, there were issues, when using SU660 bb on P990 phones, since SU660 is the O2X model specifically made for the korean market and you had to make fixes for network time and so on. With RCs ROM, that comes native with a RIL belonging to the SU660 setup, it seems for many, or at least me, that a SU660 bb is giving the best result for this nightly build.

I am absolutely positive about the way this ROM and bb is making my phone work, it is in fact like having a new phone!!

hejsan och god kvaell.

CWM update 6.0.1.5

I installed Clockworkmod ROM Manager. I started with the modded CWM here from P990 forum.

I had to install the 5.0.2.X version provided by ROM Manager app. After some time ...reboot,

and refreshing, the app offered me to install 6.0.1.5 for P990 to install.

After installing 6.0.1.5 the vibration bug disappeared :confused:.

Don't ask me why.

Hope this helps you.
[LG Optimus 2x] atg2x:
I've flashed 725, 521 and now I'm on 450 from SU660. I think that this is the best up to this point. I can call without a problen even though 12 hours haven't passed yet. As I was searching for instructions on the basebands main thread I found that phones made in Korea (check the sticker under the battery) may perform better with an SU660 baseband. Maybe thats why my phone works better with 450 baseband. I'm just telling you should consider that. I hope it'll keep running smoothly.
[LG Optimus 2x] umutozcano:
Installed 6.0.1.5 aswell, but didnt work for me. Still it sometimes vibrates. Not a big problem though, if i leave it for 15-20 sec. it stops.
[LG Optimus 2x] Shadowchaz:
For anyone who has missing camera using cwm 6.0.1.5 seems to have fixed the problem :D

Yo también soy de venezuela y tengo la 725, pero yo actualice desde paranoid android. Yo tengo un lg p990H segun me dijeron solo los p990h sufren de esto. Si me puedes decir que pasos seguiste y como funcionaba tu telefono con cm7 (por que yo me pase de paranoid android a cm7 para ver si de cm7 a cm10 funcionaba la red, pero nada) Estando en cm7 no recivia llamadas, pero si mensajes.

Sorry for that i am not so good writting in english. I was speaking with a person who is from my country so i though i could speak spanish and as i said i am bad in english.
[LG Optimus 2x] noahk423:
Well, I know a little bit of Spanish, so I understood what you were saying, but English would help other users because they can read your post too. Your English is not bad at all.

Also, sorry for going off topic everybody!
[LG Optimus 2x] alessandro_rb:
Ok i am agree the next time i will write if it is one who understand my idiom i will writte on both idioms. What i said in that post was that i have 725bb and i cant not use this rom because i have no signal in my phone. I tried cm7(i come from paranoid android) and i cant recieve calls and the power button does not work. Even i tried to do it everythin from a stock rom(GB 725 v20q) and the same issue. I dont not if this could help but my pone its a p990h.

Again sorry for my english.
[LG Optimus 2x] machoman1337:
Possibly a problem with the phone hardware, I'd send it in for warranty after unrooting.

Also quick question guys, does the baseband affect the performance/functionality of the Bluetooth at all? I'm having some weird glitches with my in-car bluetooth handsfree. After about 7 minutes the bluetooth disconnected itself and cut off my call. I had to pull over and redial by hand. Then I tried reconnecting and making a test call to a friend - same result after 4 minutes.

I'll test out the SU660 basebands this weekend once I have time. Anyone know how to back up my Fido V21b baseband just in case?

e: nvm, found out how to get my old baseband from LG. And god damn, this procedure is a little more complex than I was hoping. To change BBs on my HTC Desire Z I just put a flashable zip and booted into bootloader (not recovery) to flash it and all was good. But hey, when is anything ever simple with LG...
[LG Optimus 2x] alessandro_rb:
Well i dont know anything about hardware, but my phone worked good whit the stock rom, also with the paranoid android rom. And yes it has warranty but its not bricked and i can use a normal rom. Even one hour ago cm7 worked good(buttons, calls), when i udgrade to cm10 issues again. Then i tried to go back to cm7 and Buttons calls issues again. It could be a gapps problem? when i installed the cm7 and it works was without gapps, then i tried to install it without gapps again and issues again.
[LG Optimus 2x] sandeeppandey:
flashed su660 420 baseband this morning. All the calls related issues seem to have resolved. Voice clarity has improved considerably as compared to the last 4 basebands I tried in the last couple of days. Battery drain seems to be on the higher side, LGRIL says my ril and BB are matching whereas GETRIL says they don't match.

The only issue is that it looses network connectivity very frequently which is quickly restored by switching on/off airplane mode.

EDIT : Screens also flashes sometimes when the phone is locked.
[LG Optimus 2x] tomce5:
Flashed su660 v30A baseband and when i restored the nandroidbackup... I was asked for a pin, entered it and the phone asked me for a "network unlock pin" ???

EDIT: Went back to 725 - V20l-EUR and it doesnt ask for network unlock anymore.
[LG Optimus 2x] naazgulla:
For Indian users. I'm using 20q EUROPE Bb which u can download from Tony P's sticky thread under development forum. I installed su660 1119 ril (30a) and I don't have any problems.
[LG Optimus 2x] Ajsh:
I don't think it should affect bluetooth performance. It's just cellular network. Not wifi either.
[LG Optimus 2x] Andrija231:
I think it afects wifi cause my signal pulsates from 3 to 1 bar, and in places i had solid wifi (2 bars), i can't connect now.
[LG Optimus 2x] sandeeppandey:
can you confirm that your network is absolutely stable without any loss of connectivity. Since when have you been using the 20q baseband and how is the data connectivity and battery drain...???

Sorry for too many questions buddy but I tried 5 different basebands and none of them worked properly, now am back on CM7 :(

Baseband for Singapore m1

Hi

Does anyone know the best baseband to use for Singapore operator m1?

My P990 is a Starhub set but am now using m1. I"ve tried v20s, v20l, v20i, v10b, 420 but all have either freezing issue, dropped signal or phone dead when not in use.

Any ideas?

Thanks.

carrier: croatian TELE2

ril: default rom's ril (v30a/1119)

v20m started to generate noise on other side after a few calls. reboots helped but noise started again.

v20l first call ok, next calls was silence. after reboots other side is hearing noise.

v20s looking ok so far.

battery drain is pretty-much the same as with hackfest builds. everything else (gps, wifi, 3g) works ok.
[LG Optimus 2x] torq1337:
Same carrier and same RIL (Country mate)

And not:

0315-V10b-Baseband	MD5: 9b6f600cfa9f528595e5106305770448

?

In the picture of google+ I cannot find this info...
[LG Optimus 2x] machoman1337:
This *might* be related:

In all the testing I've done so far (still on 10/31 nightly), I only got BSODs when the phone was set to 3G mode. When I check the "Use only 2G networks" option, it has been rock-solid stable. And maybe it's not a coincidence that 3G signal bars fluctuate very rapidly while 2G bars are stable.

Thus, going to flash a new baseband once I get home today.
[LG Optimus 2x] dakoookie:
It's probably coincidence, I just had a BSOD with 2G.
[LG Optimus 2x] remygo:
do a poll for the basebands so we know what works for most
[LG Optimus 2x] sushantp666:
hi i m in india and have p990 made in korea, before i hav bb v20e,and hav outgoing call issue.

now i just flashed v30a su660 bb with v30a su660 ril all call prob solved with much better call quality or say very good call quality .

but hav strange issue with ussd code , when i dial code it show text in non English character so balance checking is a mess for of now.
[LG Optimus 2x] machoman1337:
Good idea, thanks!

edit: How does one add a poll without making a new thread?!

edit: nvm figured out
[LG Optimus 2x] stazz83:
Exactly the same experience on my phone. It seems that the 20s (0521) bb + 1119 ril combination works best for me.

Wifi and GPS both work, 2G and 3G networks too but I'm still charging the battery and for how long will it take to charge and discharge is yet to be seen.
[LG Optimus 2x] mike the mighty viking:
Been on SU660 V30c for almost 24 hours now, everything working perfect, including network time, voice clarity, dildo function in powerbutton(not there!!), very good signal, both wifi and 3/2G.

[LG Optimus 2x] rzlatic:
status update for croatian TELE2:

v20l (725), v20m (725), v20s (521) all acts the same regarding audio noise after a while.

v20q (725) is reported to behave the same by torq1337.

tried v10b (218) which lasts ok for 3-4 calls and then produce only silence, but reboot helps though.

none of su660 basebands doesn't work on that carrier., including v30a.

i guess some of us just have to wait for official ics release for p990 and baseband extracted from it - or - some magic regarding rils. i don't put much hopes on second option, and we all know how much hopes there are regarding official ics release for rest of the world :-/
[LG Optimus 2x] Takkuz:
I've tried many BB but I cannot say anything on Battery Life.

521 and 420 are the ones that give me less trouble on Italian networks. 725 v20l was too much unstable.

However I was unable to bypass a very annoying issue:

when WiFi losts connection sometimes mobile data don't turn on. I can't figure out on how to reproduce it.

The only way I found to solve it is to change between 2G/3G or turn on and off Air Mode.

Is this appening only to me or it is a common issue? I haven't red it on known bugs.
[LG Optimus 2x] ronalith:
Also if you could add to your first post which ones work okay with fido / P990H it would be great, I had to roll back to 0218 because it's the only one without problems while calling. I don't have fluctuation bars with that one too. Thanks!

[LG Optimus 2x] Soulj4h:
I just want to say the SU-660 baseband works the best for me, in terms of battery usage as well as sound/audio quality. I'm using the latest nightly. I'm in India with Airtel.
[LG Optimus 2x] calvxrr:
I had the same. You have to change RIL to ie. 1119. Then your battefy and cellular network will work fine.

[LG Optimus 2x] makgyver:
I've tried all BB and some of them worked so well first day, later, waterfall problem on calls appeared.

With P990 Korean Version, V30 BB is the best option, call audio is working properly. The only "bug" present with this baseband is that screen wakes up randomly when the device is locked. I thing that this problem might be caused by build version. I'm downgrading to 31st Oct. Due to 2nd and 3rd Nov still ocurring...
[LG Optimus 2x] ermacwins:
Can you link me to that baseband please?

Also does flashing baseband delete anything from the sdcard or is it just phone settings i.e. factory reset?
[LG Optimus 2x] jura55:
As factory reset
[LG Optimus 2x] escapantz:
I had trouble with v20d which was the default on my phone (made in korea, german box. I'm in the UK on O2.)

Static noise on other end of call etc after flashing the Oct31 Nightly. Updated to the new one today (3rd Nov) and problem persists. I just flashed to v30c

I got it from here as directed by Mike on page 10.

So far so good. First test call worked with good sound quality, 3g and wireless fine.

It does *factory reset your phone so make nandroid and restore after flashing, just follow instructions in tonyp's baseband thread page1.

Too early to be sure though but that's my experience so far. Thanks to people in this forum.

Hey man your sig says you are using the matching RIL.

I have seen bad experiences with changing RIL on CM10, is it the default one or did you change it to that?

Basically is it recommended or should I leave mine alone if it is currently working?
[LG Optimus 2x] ermacwins:
OK will flash SU660AT-00-V30c-SK-XX-SEPT-18-2012+0_CP and see how it goes
[LG Optimus 2x] makgyver:
Hi, yes, If you change default RIL on CM10 you'll get a lot of problems. When I say matching RIL i want to mean that V30A/C RIL is the CM10 default RIL (SU660 of course).

Hope I cleared your doubt.

[LG Optimus 2x] R0B3RTF1SH3R:
RIL or BB.

so you put BB v30 on as well as RIL?

i tried that on the nov 2, build. and drain was very fast. how is it for you? on nov 3?
[LG Optimus 2x] machoman1337:
If you look at the screenshots on RC's G+ profile, he used the V10b baseband.

Clever, didn't remember that. Anyway, now using V30c and things seem to be going well. At least is the BB that's going longer without giving any problems.

So I feel like I know the answer, but I feel like it can't hurt to ask: can I flash an SU660 baseband onto the P990? I feel like the answer is no...

Thanks guys!
[LG Optimus 2x] sushantp666:
Most of the tym whn u update ur phone the company update ur bb to best one ,as no official update for our phone we hav to do it manually for getting best from phone

Of course it is risky if bb corrupte whn flashing ,it will brick ur phone.

Ultimately decision is ur own

I just ended up flashing the 512 V20 one and I have radio and phone voice again, so I'm happy.

For the record, I'm on Fido/Rogers in Canada if anyone is also in my same boat!
[LG Optimus 2x] smashman42:
I started with the 725 baseband & had the silent call issue + network time borked, flashed the SU660 420 BB (made in korea P990) & the network time is fixed but random silent call thing remains, though maybe the call quality is a little clearer when it does work (or so my brother thinks on the remote end).

Regardless, on both BB it might work fine for one phone call then fail, might work for six - doesn't seem to be time or data or wifi related or anything (has anyone actually got logs of this yet? I always get it when I need to make/receive a call & just reboot to use the phone as, well, a phone)

Going to try 218 & the SU660 V30 BB when I get the time to do the backup, flash, restore thing - everything has been with the stock CM10 RIL as apparently one shouldn't change it (or so was said in the BB list/how to flash thread)
[LG Optimus 2x] sushantp666:
