I have just ordered an Optimus 2x, and thought I'd get some base knowledge about the phone before it arrives.
I currently have a ZTE Blade, and have used many custom ROMs, so am familiar with android and most of the concepts. One exception to this is flashing / changing baseband and ril settings. I can see lots of threads with downloads and how to guides, but none of them seem to answer the following questions.
1. Why do we need to make these changes at all? What is special about / wrong with LG phones? I've never had to make any such changes to my Blade.
2. As the baseband and ril combination required seems to change by country, does that mean if I take my phone out of the UK I'll need to change the baseband and ril for each country I visit?
Many thanks!
No you don't need to do that, baseband and RIl are different decause in each contry there is not same update and baseband are different,
There is not 1 baseband compatible with one country it's just because update need other baseband than before.
Hello!
The main difference between the basebands are the versions.
The Phone (talking about a p990 for Europe/UK) will most probably come with a 0725-baseband (the Version from 25th of July) the newer basebands (0823 and 0824) are either optimized for a different region (i.e. 0823 seem to be almost the same as 0725 – but came out in Canada) or are for a different model (0824 is for SU660).
Out of the box there is no need to change the baseband, but when you flash a custom rom you might need a different baseband – i.e. Cyanogenmod(CM) 7 and MIUI need a baseband that is compatible and won’t work with the newer basebands that a made for the stock Gingerbread-ROMs from LG.
CM7 by the way comes out of the box always with RIL 0218(that is/was the very first version) – and you need to flash a RIL corresponding too your baseband (i.e. 0725) after flashing a new custom rom – in this case it is a good tip is to install the app "LG RIL Version" from the market.
So that said – now a few words to the versions themselves…
I tried 0725, 0622 and 0823 – 0824 didn’t work. Some people say that BB/RIL 0622 gives best battery life and the German forum www.handy-faq.de recommends it. I personally use now the BB/RIL 0823(Canada) which is similar to the 0725 – but gives me slightly better reception indoors.
…some are always on the hunt for the newest version and use 0824 which is for SU660 (the Korean version of the 2x).
So again the only real need is if you get a phone with preinstalled Gingerbread and you want to install CM7 or MIUI - or the other way around - you get a phone with Froyo and want to install a GB-Custom-Rom based on stock rom (i.e. topogigi oder Modaco).
If the baseband works on you phone/rom-Compo it should work everywhere and there is no real need to change anything except in cases noted above or in hope for a little bit better signal/reception with a newer version or better battery life etc.
Hope that’s helped a little…

Thanks for the great explanation.... so i understand right, BB comes with the individual phone, as part of the hardware and could not be changed? onthe other hand, RIL comes with OS (ROM)?

You actually can change your BB with a tool named Smartflash, but it requires a full wipe of your phone and you need your computer to do it.
RIL comes with the ROM indeed, for example CyanogenMod comes with 218 RIL, and you can change your RIL easily with the GetRIL app.
BaseBand is a piece of the low-level software that handles the "radio" in your phone. Radio in here means components for WiFi, GSM (wherever really GSM, or UMTS, or HSPA, etc.), BlueTooth, etc. This is quite important piece of soft and not easily accessible, at least on LG (as far as I remember on HTC Desire it could have been flashed via recovery). For different countries there could be different BBs. Even for different operators I believe. This is why some of them work better for some particular people and worse for other.
Now, the RIL is a Radio Interface Library - a piece of software which comes with the system (ROM) and it gives you a "bridge" between system (kernel?) and Base Band. For the phone to work in an optimal way you need matching version of the BB and RIL. If you mix one BB with some different RIL your phone may not work (in the sense that you will not be able to make any calls or connect to the WiFi or whatever) or work in a faulty way.
Now, you'll get a phone with some BB already on-board and personally I do not think there is any need for you to change it to any other version - if it works then fine. But if you wish to flash some custom roms then they will come with some RIL and the best thing to do is to change this RIL to the one that matches your BB. There is GetRIL application on the market which makes it a piece of cake. For example: CM7, Temasek Kangs were coming with the 218 RIL which I was always changing to 725 RIL with the help of the aforementioned app as soon as I flashed new Kang. In fact the GetRIL application makes it even easier - if you are on CM7 rom then there is "keep RIL after flashing" option which automatically keeps the RIL in the version you want.
I have my phone with ICS and BB 1035.21_20110606 and i have some problems getting wifi signal when im about 5-7 meters away from the router, (Its because the walls or is my baseband?) if i chance my BB it will give me a bit more signal?

Well, the only way of checking is probably to flash new BB ... but maybe first you can check how some other equipment behaves, e.g. some notebook or netbook or maybe some other mobile phone (e.g. of your friend)?

More than likely not.
Does your router have several (external) antennae? If yes, point them in 3 different directions, that'll probably solve your reception problems with devices with only one antanna (like the O2x). And of course, how many walls and what kind of material they're made of matters a lot. Sometimes the only solution is to have more access points.
EDIT: Btw, this is a good app for analyzing signal variations etc. in your environment.
Hello together,
maybe someone can give me advice ... I just found out that my baseband is the apparently very old version 218 (the baseband, not the RIL).
I face serious battery drain problems with the latest ICS ROMs, and now I have been told that changing the baseband might actually help the issue. Seeing that this is quite a thing to do, I wonder if it really makes sense.
Can anyone give me a hint?
i am on T-Mobile UK, using an ICS ROM, my current baseband is 218.
As far as I read from different threads, it could be an option to switch to 725 - is there a chance my battery life might improve?
Hi guys, it seems that there is something wrong with the latest getril app as it won't successfully install the matching ril after successful download. Does anybody know how to manually save the RILs? Temasek has the RIL on his mediafire folder so there's no problem with the source.

Hi guys (and girls),
I'm going slightly mad trying to figure out a stable setup for my O2X. I have been switching between the latest CM7 nightlies, and MoDaCo FR19. In general, CM7 gives me quite frequent black screens, and FR19 seems quite stable. However, there is one issue that is present in both ROMs.
I am unable to get a stable mobile data connection when I switch from WiFi. Sometimes it works, and sometimes it doesn't. To get it to work again, it sometimes works to switch to 2G only (and possibly back again). I have tried several different radios recently: 218, 606, and 622, all with the appropriate RIL. The mobile data connection for 218 drops in and out at random without any clear pattern. For the other two radios switching on or off 2G only seems to achieve stable connection. However, it does not actually seem to affect whether I get a 3G or 2G signal. The display can say H or G, even when 2G only is checked. Bluetooth did not work correctly with 606.
To top everything off, the GPS does not seem to behave consistently for a all the different radio versions.
I guess that people have different experience with different radios, so which radio are the guys in Norway using? Do I really have to slog through every released radio and spend the day checking each one of them? Can I expect to find a radio/from combination that blacks to give me a stable GPS and mobile data connectivity, as well as good WiFi?
I know this has been discussed numerous times before, but people never seem to reach any conclusions. I'm just looking for advice on how to proceed to fix my problem.
I'm on cm7 .77 and i honestly havent had a blackscreen since i flashed it (yesterday morning) + battery is good now. For me this is the most stable nightly so ill stick with it for 2 weeks on my holiday )
Edit: bb .502 ril 218(i think) dont have any problems with network switching btw

You probably have to, yes. This sounds more like a problem with the specific coverage in your area and how the phone interacts with the cell-towers than an actual problem with the phone. You may be in an area with weak signals from several stations, you may be in an area suffering from sudden bursts of noise, there could be a lot of reasons for why this is happening.
First thing I'd try is to upgrade to the latest official firmware (10C - 0622 for Norway), just to have a baseline for comparison. In theory this firwmare (and baseband) has recently been validated by the norwegian carriers, and should have the best chance of success.
Then you should probably do a manual scan (in phone settings) for networks, and pick one manually.
Also try using the INFO menu (*#*#4636#*#*) and see if choosing a specific protocol helps.
If you're still unable to maintain a stable connection, I'd say that'd be grounds for returning the phone for a replacement.
Weak advice, I know, sometimes there just aren't any quick solutions.

Sort of. In this thread http://forum.xda-developers.com/showthread.php?t=1035041 you'll find complete ROMs of the previous versions. Install one of those with SmartFlash, then run the LG Mobile Update tool to get the latest.

Okay, I see, downloading now. So it is good enough to use one of the smartflash files, I don't have to use nvflash?

No, you don't have to use NVFlash. The advantage of using the smartflash method is that you get a completely "factory fresh" phone, with all the stock content present (movies, music, pre-installed apps) and you're sure to get a matching baseband and ROM.
Note that you have to flash both files, both the baseband and the ROM. The LG update tool won't update if you have a "new" baseband on an old ROM.
::Trym
So the firmwares from that post do not include the baseband? Anyway, I'm currently running baseband 405, so I guess this is sufficient to get the new update. And the new update will then overwrite everything to the latest official version, both ROM and baseband, correct?

Yes, it does. Each firmware pack comes with TWO files, the baseband and the ROM. To make sure you avoid any trouble, just flash them both, though, as you say, you can probably stay on the one you have, as yes, the LG Mobile Update tool will overwrite both the baseband and the ROM with the new versions.

Flashing of old firmware, with subsequent upgrade to latest release for Norway is complete.
I got version V10c, with baseband 1035.21_20110622, kernel 2.6.32.9. My mobile data seems to be enabled as soon as I get mobile coverage (which admittedly is poor right where I live). Even though it pains me, I guess I should leave it as stock for a day or so to see how it behaves.
I guess rooting it shouldn't affect performance in any way?
My initial experience is that it is much more snappy than the stock firmware that the phone came with, but time will show

Not to my knowledge, but I'd still advise you to wait a few days while sorting out the connection issue. Not that I think rooting it would affect that one way or another, but if you can't get it work as it is, you can return the phone in the state it is now, factory fresh.

It certainly is. It also *stays* snappy over time, which can't be said for the 10a/b versions.

The first test drive with the new firmware has been completed. On the way out it switched to mobile data flawlessly, but a longer drive it started falling out and reappearing for only short periods. When we stopped at the destination seemed to stabilise with a 3G connection again.
For the return trip I selected use only 2G network. The network connection remained stable for the entire journey.
I will have to test more, but the conclusion seems to be that it has trouble switching between the 2G and 3G networks when moving. I will try the same trip with a Telenor SIM card, and with different combinations of enabling 2G and 3G modes.
By the way, what is the difference between forcing 2G in the regular settings menu and in the special information menu?

The 2G only setting in the phone menu equals the "GSM only" setting in the INFO-menu. I'm far from an expert in these matters, this thread has an overview: http://forum.xda-developers.com/showthread.php?t=675136& of what the different modes do.
::Trym
More testing seems to indicate that as long as i leave "use 2G only" check, my mobile data connection seems to be pretty stable. It even switches between 2G and 3G, although apparently a bit more conservatively.
I guess I get to keep my phone anyway
Now for some rooting...
Just an update on the results from my testing. The second time I went out my mobile connection never appeared. This was with only 2G checked in the settings menu. In the Info menu, this corresponded to GSM only.
I then changed it to GSM auto (PRL), and then I got my intermittent mobile data again. I then change it to WCDMA preferred, and my data connection seems to be stable for now. This apparently requires much more testing...
F another chapter in the connectivity saga. Having WCDMA preferred selected in the Info menu, things mostly work, although the data connection drops sometimes.
Another problem I'm noticing with the stock ROM is that it usually is unable to reconnect to my home WiFi network when it comes within range. I have the money was selected to reconnect. Sometimes I even find it disabled in the list.
Hello, long time lurker.. small time poster.
I'm sure this has been asked a million times before.. I've tried searching to no avail though.
I recently bought the O2X after deciding my Hero is a bit old and it appears to have come with baseband 1035.21_20110622 (i understand that the only way to update the baseband manually and cannot be done via ROM flashing)
I've been using CM7 nightlies for a week and then discovered about this RIL/BB matching thing. I've downloaded "LG GetRIL" and it tells me my RIL is currently 0218 (V10B, Europe). Is it a requirement change this to 0622? What advantages do I have over matching RIL/BB and what might happen if I don't match the RIL/BB?
Are any particular basebands better than another?
Using LG GetRIL:
I've tried 0622 (V10C, Europe Open) but it doesn't seem to want to distinguish between GSM/HSPA ("G" logo in statusbar and "Settings -> About phone -> Status" reports "unknown" however it seems to accurately report signal strength for a HSPA connection)
0622 (V10E, Vodafone) seems to work fine however i'd like to know if i'm missing anything underlying that i might not notice at first. Anything I should know? Are RILs based on what frequencies my network uses or anything like that?
FYI Provider: 2degrees (New Zealand)
900/1800 MHz (GSM/GPRS) and 2100 MHz (WCDMA) frequencies
Well as I understand it non matching BB's and RILs can affect performance and mostly battery life. So as you have now a 622 RIL it should be better when making calls / using data etc.
Though I'm not hugely experienced I think thats the jist

Yeah, this is what I had gathered. Just really wanted someone to back me up on this. I'd really just like to know what the RIL/BB does. My understanding is that the BB is the layer which reads what comes from the radio interface(s) and passes that information onto the RIL "module" to interpret.. Not sure what the versions "mean" though and why there are different releases of the same version (eg. 0622 V10C/V10D/V10E).
I mean.. i'd expect the different versions (eg. 0622 or 0614) to be optimisations in terms of handling of data.. I'm just not sure how matching RIL/etc comes into play with this.
Baseband is the (low-level) firmware for the Radio (GSM etc.) module.
tl;dr:
A SU660 BB (824, 1120, 0420) will fix the weird static noise and bad call quality issue on "made in Korea" devices!
You'll find more information on this issue in this post and more information (including known issues and fixes) on BB 824/1120/0420 in the second one.
Original Post:
-------------------
I just want to share this with all of you who might have missed it within the CM7 Nightlies and Baseband discussion threads - and want to gather all information about this into one thread.
This was found out originally by vadonka here.
I found many others who confirmed that people on the other end of your call complain about static noise (like the noise when you're holding 2 phones together or standing next to a speaker).
We were not able to track down why some p990 users suffered from it and others don't. Some could fix it with the 502BB - some with 725BB and the Gingerbread leaked ROM - but not with CM7.
It appears that there are different (hardware?) versions out there.
If your device is "Made in Korea" (you'll find that info on a sticker under your battery) you might suffer from this noise issue - but not all Korea-made devices do.
For "Made in Korea" ones this noise is almost gone with SU660 BB and a matching RIL (824, 1120, 0420)!
These basebands are for the SU660 (the korean version of the P990), but work for us, too.
I'd almost given up on this issue - was using the leaked ROM (which sucks if you wanna use CM7) and intended to sell it soon. I tried nearly every possible combination of BB/RILs with CM7 some time ago - and never got rid of this problem. My poor girlfriend had to answer maaaaaaany test calls hehe.
This weekend I thought to give CM7 one more try, lurked into the CM7 nightly thread and found this Baseband which seems to fix my issue.
It's confirmed to work for the "Made in Korea" 2x's of vadonka, Sckank, TrymHansen, pastime1971 and temasek.
You'll find more infos on known issues in the 2nd thread.
So - why are Basebands which are made for the SU660 working best with our "Made in Korea" P990's? This could explain many of the "hard to track down" issues some people have - because their phones differ even if it's the same model.
You can get 824/1120/0420 BB and RIL here: P990 Complete Baseband Overview Thread
There you'll find BB and RIL install instructions, too.
positive comments
pretty similar to 725BB - if you don't have problems with 725 BB stick to it, as it might have less issues!
good call quality on both ends
good battery life (neither better nor worse than e.g. 218 or 725 BB)
good network speed & connectivity
no wifi problems

Yep, it's not perfect. As I said before, you need to disable automatic time for the moment - which is probably due to the "fix" I mentioned above.
I can confirm that 2G makes some trouble - maybe Toggle 2G/3G will help you?

well it no serious problem once its set manually and since i never use 3g i just have to think about enabling the 2g option when i reboot. maybe i could try if green power can handle the 2g only option... lets see
edit: nope doesnt look like it since green power works with the device settings which are messed up. however, as far as i experienced it might be a problem with cm7, i think i have some strange behavior with every bb except 208 if i remember correctly.

Beware of imei getting hosed when you install Korean baseband. There is a way to recover and keep it handy. I used putty on windows to fix it when I messed up a while ago.
This also explains why I my phone keeps rebooting and showing BSODS when installing Spica's HP kernel. I always thought that it was strange that there where different versions of the phone.
FYI, I tried different BB and also the 824 with MIUI but the battery drain was awful. LG just released V20M for the Netherlands so i got stuck with the 725 BB.
I don't complain about the quality and I didn't try the 824 with this version. Maybe later when i'm sick of this one .
I have a "made in korea" device with 725 BB (from v20c I think) and 218 RIL. My rom is CM7 204. I have asked a lot of my friends and family and no complains for the quality.

That's interesting.
Then there're even some more differences than "made in korea".
LG has somehow managed to fix the static sound for their v20x builds with 725 BB, but CM7 hasn't.
Does anyone have an idea how to track this down to help the devs to build a workaround? I am pretty happy with 824 BB right now, but I would prefer to have a choice.
I have a P990 assembled in Korea and it had awful call quality with every BaseBand except 0502 and 0824.
i have tried 502 and it was also pretty good but the battery drain was a lot higher:O
so im back to 824. anyone know if there is a fix for the automatic time beeing off by an hour? i remember that this was present in earlier nigjtlies and got fixed somehow, so maybe the same fix can be used on this case.

Can anyone confirm?
hmm now that you mention this i remember that i was talking over the headset with a friend and when i unplugged it he couldnt hear me anymore. i had to enable the speaker so he couos hear me again, after switching it off again everything was fine.
its like the mic didnt switch from headset to phone when i unplugged it:/

I cannot reproduce that. Which ROM are you using and which BB/RIL?
Hello!
Mine is also made in Korea.
I tested 0622, 0725 and 0823 - 0824 didn't work.
Voice quality was always acceptable didn't notice any problems there.
But overall signal reception(especially indoors) is by far better using 0823 - but this might be a special because my provider is known for bad reception indoors…
Hi everybody!
I see here a lot of people from Europe but I'm in Canada and hope for some help.
I just got LG o2x and trying to use it with cheap data plan in Ontario through 7/11 Speakout.
First problem - they filter traffic so I have to use proxy. And even then phone is really slow and sometimes even market has to be reloaded couple times... My connection drops sometimes inside the factory I work in and then doesn't pick up... I guess you know.
I've read about people saying that this phone has great hardware but poor software
I already rooted my phone (to get autoproxy running).
Now I need to put custom ROM and kernel...
That's where it gets confusing. I have Barnes&Nobles Nook Color with CM7.1 on it. And I like it. Also I have Acer A500 with stock HC3.2. But I'm still dummy in Android
From what I understand I can put CM7.1 (Thanatos2x v5.1 or Temasek's Kang), MoDaCo. Right? Any other suggestions? But then there is tonns of kernels... How to choose? I just need basic features to surf net and create hot spot for my kids tablets
And another question is BASEBANDS. What are they and should I change it or not? I'm in Canada but getRIL says I have:
RIL 0725 (V20I, Italy)
Baseband 1035.21_20110725.
Thanks for any suggestions or pointing to right direction!

You can flash CM7 temasek's KANG on your phone (link in sig)
A kernel I would recommend you to use is vadonkas ETaNa Kernel. (link in sig) It's a great kernel with good performance and battery life.
You don't necessarily have to change your baseband. Only when you really have problems with signal or call quality. A baseband is more or less a driver which regulates signal etc. Changing your BB requires a full wipe, therefore I wouldn't recommend it. If you do have bad signal, you can mostly solve this problem by installing a matching RIL with your BB. GetRIL app will tell you which ones match and which one don't. If this doesn't help, then you should change your BB.
Or, you can read a bit and not spam the fora..
Hi, I recently updated my phone's baseband to 1035.21_201111120, with RIL 1120(V20I), and ever since that I noticed I can no longer connect to my 3G network.I tried downgrading my baseband to 0823 but I still cannot connect.
Does anybody know what is the best baseband and/or RIL for the Optimus 2x?
I'm in Mexico and the phone's with the carrier Telcel.
Any help would be appreciated!
Thanks.
Update
I've since downgraded my baseband to 1035.21_20110606 with matching RIL 0606, and I still cannot connect to 3G networks or have a data connection in my phone, I will give 0823 a try now.
Strange that you cant connect to 3g.
I changed a lot of bb, and for now am using 0218 because i heard somewhere that the guy that is making cm7 for our phone is using the same bb.
And i have no such trouble as you do, in fact i have a better signal and better battery usage.
Sorry for my spelling hope you understood me.

Guys,
CM7 ROMs recommend 218 BB. Try changing your BB to 725V20Q or BB V20L/M. It works very well...if you are on CM7 or CM9ICS, then the BB are recommended by the Developers in their posts...search and read that.
No 3G is normally the cause of unsuited BB and RIL combo....also install the GetRIL app from market and check for the suited/recommended RIL for your BB.
I'm currently running baseband 0823 with RIL 0823 V21b, and everything works well except for 3G, but I just found out it's my carrier who's blocking data connections on my line, a quick visit to the customer support center should fix that!
All this time thinking it was a baseband/RIL problem!
At least I found out before doing something more drastic.

Sorry had to reply, its rare to see Telcel + Optimus 2X in these forums... I tried BB0824 and doesn't work with 3G, I didn't tried BB0823 because I though it was from China or Singapore (SU660)... I'm right now in BB0725 and 3G works really fast, it only lags when you don't use it for hours then use it again it takes like 5 seconds to "wake up"... but I guess that's a power saving feature.

I think my battery lasted a bit more on 0823. Maybe it was just my imagination
I've found 3G works fine on 0823, didn't test it on 0725 tough, maybe I'll get to that one of this days.
Thanks!

My phone didn't see my wifi router's ssid until I changed the wifi channel in the router settings from 14 to something else. At least channels 3 and 6 work for me. Of course I'm not sure your problem is also wifi channel related...
