wow! just wow! I was having problems with my SU660 on every SU660 baseband I couldn't call numbers on cdma networks and sometimes the other end couldn't hear me. Then I was wondering if I can flash a p990 bb on my su660... didn't find the answer anywhere so I took the train and flashed the v30a leak BB for P990 on my SU660, and now all these issues are gone! I'm soy happy now lol :laugh:

Thanks for these files!
[LG Optimus 2x] tonyp:
Okay, the OP has been updated:

BB's clustered by their type: ICS, SU660 and GB/Froyo

BB recommendations added into the first post (highlighted blue) as most BBs are only listed for completness and there's no reason to use them.

I might remove the links to them later, but for now I'll leave them as I think the blue colors do work quite well.

V30B Baseband added

Direct links & MD5 Hashes for the ICS BBs added

Link to the AIO Toolkit added into the 3rd post

many small updates to the FAQ entries

I added a ROM type to RIL type graphic (see below).

flagged an xda admin to delete the poll (only admins can do that)

replaced the dark green colors with some shiny ones =D

I think the thread is now well prepared for 2013 :D

Any feedback or further suggestions?

Added graphic. It's Christmas, I can't expect you guys to look for it in the OP hehehe
[LG Optimus 2x] massimo69:
Hi tonyp, I noticed that you did not categorize the BB's by regions, my question is, would there be a difference between a V30a Eur BB and V30a BB which was released for the Asian region?
[LG Optimus 2x] Impact7:
Not sure if you already talked about that but v30C, the SU660 BB just gives me GPRS. 420 BB, which is from the SU660, also, let my phone link in EDGE and HSPA. Does somebody know why? P990 basebands kils my battery always in a few hours.
[LG Optimus 2x] tonyp:
I can't tell you why, but I've read a couple reports like that.

That's the reason I recommend the 420 BB (which I'm using myself) instead of the new one in the OP.

It always depends on the phone and carrier with SU660 BBs. Some people don't even get a signal with them - others no 3G or can't call certain telephone numbers.

That's why I wrote in my FAQ that I wouldn't recommend a SU660 BB unless it fixes some problems of yours.

Well, you tell me.

Compare the MD5 hash of both BBs, if they're different I can add the missing one to the op.
[LG Optimus 2x] massimo69:
I have no problem with using V30a europe since it came out, I only asked an empirical question to inform myself and others should they need to since there is no reference to regions in the FAQ. There is got to be something there thought since all the official upgrades come with a region specific BB. Just my thought I might be wrong :)
[LG Optimus 2x] tonyp:
@Impact7 & massimo69:

Sorry lol, I had mixed the answers to your posts accidently :D

The md5 answer was directed at massimo, the other one at Impact7.

Fixed it in my above post. Now it does make way more sense hehe

Lololol, this happens if you're typing on your phone on the go :laugh:
[LG Optimus 2x] crossmission:
I nvflashed v30b BB but I still see 20121130 on baseband any ideas?

running carburano's ics 1.0
[LG Optimus 2x] massimo69:
no worries, If I came across different md5 I'll let you know... :silly:
[LG Optimus 2x] Vippo321:
The V30A or the V30B is the baseband released for europe?
[LG Optimus 2x] bitdomo:
V30a is released in europe and v30b is released in south east asia. I tried both BB. I had a little worse 3G coverage with v30b. The phone often lost 3G even if the signal was strong. But this is my personal experience.
[LG Optimus 2x] salisbury_steak:
Just to verify, we are supposed to use Smartflash for the BB's right?

I downloaded v30b, smartflashed it, encountered an error about the phone timing out (on all 3 tries), then went ahead and rebooted the phone, GetRIL does still say that I'm on v30a (EU). Can people on v30b confirm if GetRIL is able to pull proper info for this BB? (If not, how do we know that we are on v30b already?)

Just in case you guys are wondering, yes, I did check the md5 sum.
[LG Optimus 2x] SREEPRAJAY:
You are right buddy....no nvflashing for the change of BB....only Smartflash or KDZ flash....

I smart flashed V30b and all I found in my device as well as GetRIL app that I am on v30a....it does not identify it as V30b. Even the RIL and BB recommendation is done as per V30a.

One of the other guys (think it is trocopassu) reported that V30b is identified well as V30b when you are in cm10 and cm10.1 based ROMs.

if you have an issue, there are some short tricks to make the smart flash to work....you can find a few in this thread as well.
[LG Optimus 2x] Morutimeru:
v30a and v30b download links are broken... there was a link with v30a BB + ril before:rolleyes:
[LG Optimus 2x] salisbury_steak:
I just clicked on both links, they're both working. (It only downloads the FLS files though.)

@all: Am I understanding the table in the 2nd post correctly? That after you flash v30a or v30b in ICS, you don't really need to change your RIL anymore? (Cause I just smartflashed v30b, but I also placed a v30a RIL via GetRIL.)
[LG Optimus 2x] -sandro-:
I think I made a "mess". I was trying to flash V30A with Smartflash...I've done it so many times that I just got confused and I used the other method (normal D/L) with multiples files for this that just has one file. Now that I try to use the correct method (ROM copy D/L) once the process reaches "trying to communicate with IFX modem" the phone turns off and restarts with black screen so it goes the flash fails (timeout). Everything else works I can still use the phone. Is it possible I made changes internally so I can't flash new BBs now?
[LG Optimus 2x] -sandro-:
edit: solved by using old drivers
[LG Optimus 2x] tonyp:
New FAQ entry added. As some people might be suffering from this issue for quite some time now I'll post it in here as well:

Maybe this does fix the odd data loss after wifi bug for some people? :fingers-crossed:

Why isn't data coming back after turning off wifi?

That's an issue a couple users have with all ROMs and all Basebands.

It seems that there has been found a possible fix by dcseek.

Apperantly (at least for some users) it's caused by an IMEI loss (see the next question).

Follow the instructions in this post here to read more about the solution.
[LG Optimus 2x] paleee:
Sirs, if you don't mind, I'll would share my experience:

Situation: P990 (obvious) with Pengus' CM10 on new bootloader with SU660 Baseband (v20m).

I had call disconnects so I decided to flash the recent P990 v30b BB with smartflash - and its failed many times! Spent almost all day to fix the problem. Smartflash randomly gave me "Timeout error" near the end and "code download fail" around the middle of the process with a USB disconnect sound. Tried on 3 different machines, both WinXP and Win7, 3 different cables, different driver sets... nothing helped. And of course, my phone wasn't worked with a "half-flashed" baseband, couldn't recognize SIM, no network, battery percentage stucked at 999 %.

Long story short, my final approach was to use ProgMaq's Full Brick Repair, got a "simple" CM10 with this great tool and after that I WAS ABLE TO FLASH THE NEW BASEBAND!!

:)

(I don't know what was the real problem, new bootloader? New layout? Different recovery? tonyp, maybe you know the answer ;) )
[LG Optimus 2x] salisbury_steak:
Hmm... I was getting the exact same error actually. "Code download fail." May I know which baseband you're using now?
[LG Optimus 2x] tetsuo55:
I had the same problem, all i did was flash the brick repair, boot the phone once, and then flash the baseband again and it worked. In my case it was 30a.

We should probably add this to the first page.
[LG Optimus 2x] salisbury_steak:
Hmmm... my issue is... progmaq's full unbrick tool seems to be designed for CM10.1, am I correct? And I would like to flash Django Manouche X.

I'm wondering if I should try to reapply BB v30a on the weekend, or if I should just leave everything as is. I mean, even after my v30b code download error, I can still use the phone right now. :D
[LG Optimus 2x] svein01:
For any new ROMs using the new partition layout (such as Django), use the AIO toolkit by Spyrosk to prepare your phone. That thread is a sticky in the Dev forum.
[LG Optimus 2x] tetsuo55:
you stay on the unbrick version only for the duration of the flash, then you can go to any other rom you want. But if you do take this road and have any problems with wifi/cellular i suggest erasing cal and re-entering your imei.
[LG Optimus 2x] salisbury_steak:
Thanks svein, that's the thing though, I am already on the new partition.

I do remember using the AIO tool (nice stuff), as it was part of carburano's instructions.

So this does mean that from my current new layout, using the unbrick tool will bring me back to the old layout. Is that correct?

Hmmm... maybe this is a point in time where "if it ain't broken, don't fix it applies" lol.

The only issue currently have is a higher than usual wifi drain. (Which some other users also encounter.) I might be better off just doing a full system wipe if I get desparate.

Once again though, thanks everyone! :)
[LG Optimus 2x] SREEPRAJAY:
@salisbury steak,

buddy, have you tried flashing the V28G Baseband?

for some, this was working good and even better battery perf.....

Try it ;) you never know in life...lol
[LG Optimus 2x] salisbury_steak:
You know what, no, I actually have never tried that BB. I jumped right into v30a since that was the BB that DMX was based on. I'll give it a shot should my I have time tomorrow. Thanks buddy! :)

[LG Optimus 2x] paleee:
I'm using v30b without any problem :)

It was my first thought, I've just forget to mention it in my post, it would be useful in the OP.
[LG Optimus 2x] tetsuo55:
Wiping call fixed a lot of problems for me but the wifi drain is still the same.
[LG Optimus 2x] mintjustin:
So, I am running on a CM10 ROM with baseband 30b. I should just leave the default RIL alone. No touchy? :p
[LG Optimus 2x] tonyp:
Touch it and I'll touch you. With a chair. In your face. :D
[LG Optimus 2x] x_justin:
I noticed also! When I went from 0725 to 28G it felt like WOW, really fast 3g connection. That feeling was gone when I tried 30a. Strange but I guess it should be true:confused:
[LG Optimus 2x] SREEPRAJAY:
it really depends on region, device, make and a few things more....but V28G was good for sure.

can also be a placebo effect.... :p
[LG Optimus 2x] x_justin:
Yeah I know, it's not easy... I'm quiet satisfied now since I've got my imei back and have the radio calibration wiped with smartflash! Signal strength is the same but I haven't had any signal loss since... Apparantly I've lost my imei more then a year ago when flashing bb failed one time. Since then I still had a working data connection, so I didn't notice my imei was lost (it was not lost it contained almost only zero's).

So when people complain about a baseband... it could also beïng caused by old calibration data or a corrupted imei... When you ever flashed your baseband, there's a chance you've lost it. When you ever changed your baseband, there is a chance that remove cal data will improve your phone dramatically as it was in my, and many other situations.

Definetely this was improved after erasing cal data and had nothing todo with the baseband itself (because I flashed the same baseband back after it):

- No more signal drop outs, only in buildings off course

- More types of data connection (like HSDPA type 3 to 10 instead of unknown or just 10)

- Less battery drain, I saw lots of old half unreadable data passing the screen when monitoring with hyperterminal before erasing. After erasing the screen was blank.

- Stable transition to mobile data after losing wifi connection in stead of toggling to flight mode and back to data.

pop-up "default message"

I keep getting this message that says "default message" on my screen.

BB: V30B

ROM cm-10-20121228-UNOFFICIAL-p990 (pengus77)

What are this messages and how do I get rid of it?
[LG Optimus 2x] Ska1i:
Hi,

I smartflashed the V30A BB, because I'm trying the official ICS and have some issues (hot reboot and call aborts). You wrote, that "Erase call data" while flashing a BB, could fix some issues, right?

All I found about this check box is -> leave it UNCHECKED and no description why :confused:

So here is my question: What does this check box do and what could breake on my phone, when I check it

Of course it could be the lousy ICS release, which causes all my NEW issues :mad:

Regards & thanks
[LG Optimus 2x] x_justin:
Hi! Well, I am not the one who found this sollution, that was dsceek in the 2x development section. He did a good study. There are two reasons NOT to check it:

You will wipe your imei, so your phone looses it's identification number. You also wipe your radio calibration, but apparantly this data is actually defined in the baseband itself so if you dont erase it you kind of mix old cal data with a new baseband (which can give conflicts like sudden signal loose because radio crashes or batterydrain because of sending useless data over the radio). So... the only problem is loosing your imei, but my guide is about how to put your imei back.

Good luck!

In radio logcat i found a Entry:

What does this mean?
[LG Optimus 2x] AnishTS:
To flash baseband is it mandatory to have a nandroid backup. ie, after flashing baseband whether I can go to recovery menu and flash rom from sdcard ?
[LG Optimus 2x] SREEPRAJAY:
not required mate....

but it is an advantage to flash a BB with a nandroid backup of the ROM you want.....which means you can restore all the apps and user data by restoring the nandroid backup after the BB flash.... otherwise flashing a BB will wipe all the user data

Hope it helps
[LG Optimus 2x] lekker_gcp:
Well, for a long time I had bad network signal and sometimes had to reboot to get signal back, this happened in Froyo, then GB, then I replaced the sim card and it got better but kept happening sometimes on ICS too. Tried many BB, and only now I read carefully the SU660 BB part and realised that my P990 says "made in Korea" so I tried the last SU660 BB (v30c) et voilá!!! Now I have a good ROM (DM 1.2.1) with a always on signal!!! at last!

...But there was a battery drain problem... so I tried v28G which worked good for a week, good battery, good signal, until I started to loose network when turning data on/off... So now I'm on 30a and the battery is going fast too... and the network signal sometimes goes off and I need to reboot it...

Is there any BB suitable for this??? I guess next I'll try Su660 v20m... :/
[LG Optimus 2x] dorwoo:
When i try to connect in smartflash mode it remains one message:Installing driver software-Unidentified Device and because of that i cant use smartflash.I tried unninstalling driver but still the same.Any ideas?

[LG Optimus 2x] Garfields 2X:
hey guys im on the latest rom by pengus and his latest kowalski kernel (11p4) - new and unlocked bootlader..

so the thing is i wanted to change my current baseband (v20m) an su660 basebend - because i have a p990 made in korea , to the new v30a baseband and matching ril.

i used smartflash to do so but after the install, im not getting the "successfull" message, im getting: flashtool is diconneting target - and a few seconds later an error but when i check info, it says that i have the new baseband- but and this is curios, there is no full wipe- which should happen with a fresh install of a baseband?

so anybody with the same experience? btw i checked diffrent cables and usb-slots...

thanks for ur help
[LG Optimus 2x] R0B3RTF1SH3R:
you have to do it before you change to new bootloader
[LG Optimus 2x] Garfields 2X:
thats not true, i was able to change bb with the new bootloader without any problems.. until now..
[LG Optimus 2x] Justray:
I just flashed the latest BB V30A and weird stuff happened, it says

complete sync error!

But after turning on my phone I was amazed to see it booted my CM10.1, then I though :) the flashing failed... because its supposed to erase everything uh, and for my surprise there it is, latest BB, signal and 3G works so... :eek: im bafled, I manually erased my dual boot setup and re partitioned, re flashed bootloader, then reflashed BB, same error :rolleyes: any thoughts?
[LG Optimus 2x] R0B3RTF1SH3R:
how did u get to s/w upgrade mode? the only way i have tried, which resulted in the ABOVE POST which i needed promaq cm10 unbrick, was to after flashing new bootloader /nvflash rom. while it still shows S/W mode. just initiate a Smartflash BB change.
[LG Optimus 2x] AnishTS:
I am trying to update to v30B baseband . But I am getting time out error. Is there any other way to fix this issue other than full brick repair ?

once booted its showing unknown base band.

[LG Optimus 2x] Chris4evernoob:
Does anyone know where i can get the 0725 v10b matching RIL? (Or just any 0725 for that matter) GetRil and LG RIL Version don't seem to work with ICS/JB.
[LG Optimus 2x] SREEPRAJAY:
likely in tonyp's upload folder or Temasek's folder.....check for it....

but just for your information.....GetRIL (pro)but should be free version too.....works very well for me.

BTW, are you using the latest version from play store?

EDIT:look at the attachment...I am on ICS Stock based ROM too. :)
[LG Optimus 2x] Chris4evernoob:
In tonyp's hopto.org, there are the basebands but only the .fls BB files. In his goo.im folder, there is "P990-Stuff>>Basebands>>RIL" but there are only v28g and v30a files. Temasek's hopto doesnt have anything related to BB or RIL.

In GetRIL, i can select RILs but the "Download & Install RIL" button stays greyed out. It also says i have 0823 RIL but LG RIL Version says "CM10 1106".
[LG Optimus 2x] SREEPRAJAY:
I have checked before....LG RIL Version is not updated with the ICS ROMs. If you are in CM ROMs then there seems to be a mis-match with GetRIL too but....just refresh once (top right corner i think) and it should normally work if you are in the ICS ROMs.

I will check if I have the RIL and upload it if I find it.you can then add it manually

I think this is it.....check it my friend....I dont own any responibility for any damage :p....maybe you can use the GetRIL to check it
[LG Optimus 2x] SREEPRAJAY:
there is another way around for getting a RIL....mostly all CM7 ROMs were with 218 RIL....so you can extract the RIL form the ROM zip file....system/lib and you should find it there....without any big issue...

Hope this helps you
[LG Optimus 2x] Chris4evernoob:
The attachement is libril.so but i thought the ril was lge-ril.so. In system/lib there are both files.

I guess i can get 0218 RIL but i thought there would be a specific on for 0725
[LG Optimus 2x] tonyp:
the ril won't work on ics anyways so i don't see why you want it.

your posts show that you don't really know what you're doing, so I'd suggest you stop it or you'll end up without signal ;)
[LG Optimus 2x] Chris4evernoob:
OK. I'll just reflash my original BB then. Don't want to risk screwing up any further.:o
[LG Optimus 2x] flat__line:
First time BB only flasher question ...

When I flash a new BB, the phone will directly boot to recovery at power on with battery reinserted or shall I have to access CWM otherwise?

Thanks, _r
[LG Optimus 2x] SREEPRAJAY:
First, when you smartflash a BB, you do it without the battery. Once the BB is flashed, re-inserting the battery will, only power ON with the power button pressed. Recovery does not come on with normal smart flashing. For smart flashing, you just need to hold the volume down button only while plugging it to the PC...so it cant enter recovery even with the battery re-inserted immediately after the BB flashing.

Accessing the CWM is only when the volume down and power button pressed simultaneously or by some app (quickboot etc)when the device is working.

Hope this will help you

[LG Optimus 2x] mas2112:
Anyone experiencing bad battery drain with V30A? I'm running kk kernel with temasek cm10.1, and the battery drain is sometimes really big. I suspect it's the bb, since the battery drain is really low when airplane mode is enabled. Anyone know if V30B is better, and works in Europe?

Btw, I'm often in the situation when my cell signal is bad. When the signal is good, it seems the battery drain is lower.
[LG Optimus 2x] SREEPRAJAY:
just a small input my friend....

you can also use the older GB Basebands with ICS....only thing in the info"about phone", you will find unknown baseband shown....but if the comm and other related stuff works who cares.....
[LG Optimus 2x] mas2112:
For some reason I was under the impression that the ICS basebands work better with cm10... I guess I'll try the v20s, see if that makes things better.
[LG Optimus 2x] black_mamba99:
Someone plz help me out....

My phone is having standby battery drain.rest all is working fine.

in battery stats...it says cell radio and phone idle consuming the most battery when phone is sparingly used during the day.

I am getting about 2%/hr battery drain with wifi off,data off.

using cm10 pengus latest rom and latest kowalski kernel 116.

tried PA,switching to ICS ROM,did a factory reset and installed apps on a clean partition...still I am getting the same battery drain problem.

tried all recommended basebands of p990 and SU660 since the latter gives me a better call quality (made in korea battery).still I am getting the same battery drain problem.

what should I do?
