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.
Hello All,
Have just started using this forum and failed to introduce myself previously, my name is Jay; I am 27 from DC but in Afghanistan for a few more months (yea..sucks) new to rooting, flashing and all that but I have recent interest in it and it passes the time better than most thing we are "allowed" to do over here.
I just switched from a HTC Desire to a Galaxy Captivate
So far...I have unlocked it (via cellunlocker.net), upgraded to the leaked 2.3.4 Gingerbread, Rooted using the 10step method posted here, Installed Victory v1.5 Rom, tried flashing Talon kernel but bricked the phone and had to redo the above...
My question is to those more knowledgeable than myself with all this...what is the best Kernel, Rom, Modem...whatever else...that I can have on this device to keep it running smoothly, fast and reliable?
I do all the basic call, txt, surf...play games, watch movies, use apps, etc...not a developer but want my phone to be tweaked as much as possible so it does not seem outdated or lag with new things being added.
My current settings are:
Baseband I897UCKH3
Firmware 2.3.4
Kernel 2.6.35.7-I897UCKH3-CL461307
Build VictoryRom_v1.5
There is nothing wrong with the phone...as I said above, if I could do more to it and have an overall better device and pass some time here I would enjoy that. Victory seems great but all I notice myself is the battery indicator has changed and...thats about it (a lot likely goes unnoticed by me)
I do have one problem with the phone that maybe a different modem can fix? (I hope) for some reason my GPRS will not work out here with my browser...I can use the market and apps that connect to the internet but my browser seems to be WiFi only. I have changed the settings from usa to europe since I am using a sim from over here but no luck...and added the gprs settings to the phone which allowed apps internet access but zero for browser..any ideas?
I really thank anyone who takes the time to reply...I am sure teaching a new person in this is annoying just as showing the new guy here how to clean his weapon...lol...but we were all new at everything once and I thank you all for reading my novel
-Jay
Jay,
Thank you so much for your service and contribution to our freedom, I know it must be hard to be away from the life you once knew. Hang in there It's not for nothing. Hopefully someone will be able to help with your GPRS settings. I am running the same setup on my captivate only I have used Boogs kernel to install clockwork recovery as well. You can flash boogs kernel over the kernel you have now and that will let you flash roms or speedmods later. If I were you I'd keep my eyes peeled for GPRS settings in your area and wait for EXT or speedmod kernel for the 2.3.4 They are saying RFS is pretty quick to begin with though. It may be hard to beat but im sure one of these great Devs will figure out a way to make 2.3.4 smokin fast. Once again thanks for doing what you do. Keep your head down Soldier!

If you like using your mobile providers Net, you might give I9000 ports a try. They allow for better Upload speeds but you will sacrifice Audience chip support (noise suppression processor that only I897 have). Also since I9000 source usually drop first they have all sorts of kernel mods like Voodoo sound, Voodoo color fix, BLN, init.d files tweaks like V6, among many more. Sadly I897 native roms always play catch up with I9000's.
Personally I prefer native rom, because they tend to run smoother for longer periods of time (I9000 tend to slow down over time on my phone, but thats just my experience) and I don't use ATT's network a whole lot (90% of the time I'm around a wifi connection) and I like the audience chip, it is a phone before anything else.
Edit: Also there isn't a "best" rom, kernel or modem. Each rom has their own pros and cons, same as Kernels. And no 2 phones are the exact same so not all of them take well to all the tweaks, mods, etc. And most of the time i9000 kernels wont work with i897 roms, at least in GB.
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.
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
known issues with SU660 BBs (824, 1120, 0420)
automatic time is not working

Fix:
There is a fix from pastime1971 if you're using CM7, you need a CM version with the following fix cherry picked though: "Change Iaaf7f1c4: LGEStarRIL: Apply DST regardless of Infineon fix (PATCH #3)"
In temasek's or owains KANGs this fix is already included.
Head to their threads to download a ROM and get instructions how to enable automatic time.

Well your phone isn't compatible to 824BB - you should install 725 or 218 instead.
As it's not compatible you shouldn't suffer from the "Made in Korea"-Noise issue anyway.
So this is the dial-up-esque noise that pre-warns of any impending text messages/phone calls?
plz tonydl i wana try 824 BB and RIL , i'm on cm7 7.2 the latest kang , but can you tell how to change it ?? (a mini guide plz)

No - it's a quite disturbing noise on the other end which won't stop. If you're not suffering (better: the people whom you're calling) I wouldn't advise this baseband.

For getting the matching RIL I use sibbors "GetRIL" app: https://market.android.com/details?id=com.sibbor.getril
i flashed 824 yesterday and i have a couple of problems with it.
every reboot i have to set 2G only again, seems to reset/ignore the GSM only option and the timezone is 1hour behind...
so far i have not noticed any noise like i had with 725 but havent used it a lot so i will continue to listen and ask if its better than before

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.

Head over to this post for a KANG which included it and gives a description: http://forum.xda-developers.com/showpost.php?p=20595849&postcount=12065

Another small issue: the call initiation is a bit longer - if I'm too quick with saying "hello" then the other end won't get it (and vice versa).
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…
I'm having this weird issue with my galaxy s. The weird part is that over the last couple of weeks, reception has been zero in a period of time that's been steadily increasing. I've been able to restart the phone to fix it, until yesterday when I couldn't get any reception at all.
But wait, there's more! My sim card works in my girlfriends gs2, her sim card works fine in mine. So, it's only the combination of my sim card and my phone that gives me no reception at all. Also, what could be causing reception to steadily degrade to the point of none at all?
I'm running the team icsgs rc 4.2 with semaphore kernel, but I couldn't post in that thread because of my low post count. So, what I'm thinking is that I should try another modem before I try to wipe and perhaps install another rom. My question is, do I have to use Odin to flash a new modem, or can I just use cwm? Anybody have a suggestion for a particular modem?
So, Ive flashed the KF1 nexus modem, no change at all..
The only thing I haven't tried now is going back to stock rom... Anyone?
I have problems with Nexus S modems (that are so popular last weeks). For me the best modem is original JVU (the CM version). Try with that modem (if not with it already).
Try with the original build, because that reminds me for a hardware problem. You can debug the problem with experiments. Try everything before going to service.
No EDGE/GPRS signal
Hi!
Because I cannot post in development section, I'm putting this here...
Last week I've tried 9 ROMs and different modems and the problem was always the same...
When I'm on UMTS/HSDPA signal, everything works great, but when I'm on EDGE/GPRS signal, I cannot even make a call, or send a message.
This problem is happening to me for the last two weeks... :-(
ROMs tried: teamhacksung's CM9 ALPHA for Galaxy S (BUILD 17, 16), Team ICSSGS RC4.2, AOKP Milestone 4, Build 28 (now using), Dark Knight 3, 4, Elite V9.0
Kernels: Semaphore ICS 0.9.5b, Devil Skorpion Kernel, Midnight ICS 0.9.0-2-HUGERAM (now using), and the ones which comes with ROMs
Modems: XXJVU, XXJVT, XXKF1, XXKD1, XXKB3, AUCKF1, XXJVK, XXJVO and now I'm using XXJW4
When I flash DarkyROM JVU-RE with Odin everything works fine. :-S
So.... I think the problem could be in the ICS ROMs or kernels
If anyone knows how to solve this problem with 2G networks, I would be very grateful.
p.s.
Also, I find my SGS very often bootloop without possibility to enter CWM when I'm flashing new ROM.
And I found a solution for those bootloops, because I'm tired of flashing with ODIN a new GB ROM constantly... after bootloop, I use FixRecovery and flash it with Odin, then enter CWM and install Team ISCSGS RC 4.2 which only starts and make boot image and flash new CWM, so I can flash other ICS ROMs...
Why I'm telling this? - only because the devs could see if they can make other ROMs to start with flashing like Team ICSSGS RC4.2.
Sorry for my bad English. :-$
Edit: @adytum
I have also thought that my SIM card was a problem, so I've exchanged it. Didn't help....
At first the problem was like yours...
Will attempt to install the original stock firmware today (boooo, downgrading from ICS ), but I have my doubts. My service provider have started technical problemshooting at their end, but I have my doubts there too.
To add to the confusion, I discovered that 3g and data traffic works fine, wireless works fine, but calling doesnt work at all. As mentioned, if I put my sim in an other phone, or another sim in my phone, it always works.
I just managed to make it work. In test settings, INFO part (*#*#4636#*#*), after 5 times setting WCDMA only, my phone works only on 3G networks and now I can communicate because it doesn't switch to 2G...
But, I would appreciate if anyone find out solution for problem with 2G.
I hope that this isn't problem with my phone.
As far as your problem, I would try to reinstal the modem, because after trying a lot of new ones, sometimes it just doesn't recognise which one is instaled. JW4 seems the best for me...

Here is link where you can get JW4 modem. Flash it through CWM, reboot and check if that will help.

If I could hug you, I would! This modem seems to have solved all my issues! So, yes, our problems are probably related to eachother and to ICS. Never got around to try stock or darkys rom, but I'm guessing that would have fixed my signal issues too.
A million thanks to you! (Now I'm just crossing my fingers for stability and that this is not a fluke!)
Well, I'm glad to see that it works...
For me, JW4 have the best signal, and is very stable. And, you know, I've tried almost all other modems, and they were all pretty much the same.
I wouldn't tell you about that modem if I haven't seen that I have HSDPA reception (-95dBm) in the places where I had very poor 2G signal (-103dBm) , and no 3G signal (-111dBm) at all before.

Have you tried if other sim cards work in your phone, or your sim card works in other phones? If so, I'm thinking that these issues have something to do with the service providers not being up to date regarding newer android versions. That's really the only logical conclusion I can draw.
I did call my service provider earlier today, they were as stumped as I am, but did suggest to try connecting with 2g and 3g enabled respectively.
By the way, your english is just fine
Well, I was working as tech support at my provider (until last month), so everything is fine with network and signal.
Also, first thing I did was to check SIM card and it is OK. I even exchange my SIM because it was 5 years old -just in case...
Everything works great in other phones, but in my phone only 2G network reception doesn't- even with other SIM cards...
That is very weird, but, I finally managed to set only 3G so, everything works now, but with very poor signal in places where I had EDGE coverage before.
I even thought that could be a problem with my device, but when I flash GB ROM, everything works, so I'm thinking that it only could be a bug in kernel or ROM.
I didn't see much people complaining about this, maybe only because they are constantly on 3G...
I don't know...

And...
Btw, service providers have nothing to update or upgrade with signal, because it is only frequencies they have to maintain and base cell as root. That's why we use SIM card which help our phones decode signal.
Only thing that is up to providers is maintaining the level of signal and its communication with central station, along with base overload in urban areas.
Sadly,
In 98% of problems, it is up to SIM card, device or software on it.
When the problem is up to service provider, everyone in that region- on the same base cells, have it. :-(
So, obviously it can only be ROM/kernel problem or device(hardware) problem. :-(((

Obviously the main difference here is that the only thing that ruined reception for me was the combination of my sim card and my phone, every other sim and phone combination worked.
You probably have more extensive knowledge about this than I do, and you're probably right inducing that it is a rom or kernel bug.
In that case, there are two options;
Maybe SIM card didn't set well, or SIM card is damaged.
You can try to see if it is damaged or has something on it and clean it. Otherwise, if it is damaged or just won't work, go and exchange it. It takes just a 5 min. And if you tell that SIM stopped working, they won't charge you anything. And, after that, you'll be sure that SIM works.
It also happened to me in the begining, and I was wondering why my SIM won't work only in my phone. Then, I place it in my old Nokia and after 2 days, I couldn't talk with people and the signal was OK. Then I exchanged it, and everything was OK.
Now, obviously I have a problem with a phone. :-(
Maybe it is a message to me to buy a new one... Note, maybe... ;-)
Anyway, I hope that I've helped you.

Seems I was a little too quick. Problems started again today, but I've managed to fix it for now..
I installed jvu from odin as per the first post in the elite, ICS beta 8 thread. Found that everything worked fine in jvu, and now it also works fine in ICS.
