Can someone help me ? I've been using 725 10d since ever and when I went back to an old phone I realized how bad the 2x sounds in voice calls quality! Voices are usually muffled and distorted so I tried different 725s with the same result. THE 1120 and 824 sound perfect instead but the majority of service numbers wont work I cant hear any sound... completely mute even though the call is established. Why? Always using matching RILS
[LG Optimus 2x] tonyp:
Yes that's a known problem with su660bb bbs, nothing (we know of) you can do about it.

Try 521, 327 or 313bb they should have a better sound quality for you, too.
[LG Optimus 2x] -sandro-:
I tried 521 and 313 and they both sound bad :( Basically the only ones that are good for me are the ones that won't let me hear the other party in a call, cool! :(
[LG Optimus 2x] goodmamba:
I hate quoting myself :)

Anyways, to clear the issue, the problem was the touch screen replacement. The touch screen was faulty and I had to re-replace it.

During the process I concluded a lot of things like call quality, stability, usability and many more.

As the result, I flashed the official LG ROM V20c with the corresponding baseband and RIL and I was amaze of the nice call quality. This result made me to upgrade further to the latest baseband and RIL (0521 - V20S). The sound quality was way better than CM7.2.

Being addicted to flashing ROMs, I found a stock ROM with a improved kernel for me to get the best sound quality and general performance with good battery life.

The result was DjangoManouche 1.5 Beta4 [20S] with ext3 HP2 kernel not-clocked. Right now I'm very satisfied with this solution. I enjoy my HDMI output, video calls, and many other things I missed with CM7.

For me, the CM7 experience was nice but the echo heard when using the speakers in a call made me totally unhappy.
[LG Optimus 2x] -sandro-:
I tried that rom with 521 as you said and I hear no difference from cm7. I find it unbelievable that I can't get a good sound quality on a phone (on this phone!) unless I accept to not hear the other party sometimes :S
[LG Optimus 2x] tonyp:
You could probably have "fixed" the echos with a SU660 Basebands. I suffer from a terrible call quality while using CM and P990 Basebands, too.

But as you see from the last posts this "fix" is not a solution for everyone - I guess I'm lucky that I almost never need to call any service numbers, as this just wouldn't work.

As CM7.2 is stable you (or anyone) could submit a bug report to CM including logcat and maybe a recorded soundfile. Ricardo might be able to fix something, I don't know. He could adapt the v20x RIL behaviour LG introduced with GB, but he said before that this would be a hell lot of work - if enough people are having this bug he might reconsider though.
[LG Optimus 2x] -sandro-:
I have the same problem . I wonder who's responsible! :(

Will 20x RILs fix the problem? I tried before with a stock rom and no difference!
[LG Optimus 2x] tonyp:
For me on Stock ROMs the combination of a Gingerbread BB + RIL did fix it, yes. And I know several people with the same experience.

But I don't like the stock feeling, I prefer Cyanogenmod builds.
[LG Optimus 2x] -sandro-:
What is the technical reason CM7 can't handle 20x RILs?
[LG Optimus 2x] tonyp:
Let's please try not to discuss the same question at two different threads:

Added 327 to GetRIL, so make sure to update ;-)
[LG Optimus 2x] mikeszf:
Hey tonyp, can I flash a new baseband from owain´s rom with the driver you posted yesterday or should I use a gingerbread rom? or a gingerbread stock rom?
[LG Optimus 2x] tonyp:
Your post doesn't make sense.

Owains ROM doesn't include a baseband.

The drivers I modded have nothing to do with a baseband installation, they're for adb.
[LG Optimus 2x] mikeszf:
You know what, now that I read what I posted I think you're right. Any way you give me an answer, not the one I expected but solved my doubt, it should not be related at all :p
[LG Optimus 2x] yoritomo.bo:
Worked nice for me. I have installed 1120 and fixed the RIL installed by default with CM7 with GetRIL. After that I could at last talk with my family using my phone!
[LG Optimus 2x] pitbullx:
The battery drops very quickly.

BB:725 and RIL 725 V10d Europe.

how i do improve the battery.

i dont understand any of this.
[LG Optimus 2x] Penetal:
Hey I have 0223 BB and the matching RIL isnt in getRIL so I was wondering if you could help me locate it. I have Nova HD Rebuild 1.1.0 right now (based on CM9) if that means I have to use a special type.
[LG Optimus 2x] mavEEE:
Hi if I flash a new baseband will it cause a fullwipe I read something like that?
[LG Optimus 2x] slebit:
Yes, it will.
[LG Optimus 2x] Psipherious:
You need to do a nandroid backup (which is basically just a regular backup using clockworkmod recovery).

I just flashed my Baseband for the first time a couple days ago, did a backup first, flashed it, restored the backup. Everything working just the same as it was before, phone's been running with no crashes and stable since the Baseband flash.

Good luck to you!
[LG Optimus 2x] presuntinho:
A few days ago i started to have problems again, then i tried the 420 ril. My O2X could not start a call, it shows a menssage saying the call is terminated as soon as i press "call".

Then i had have to back to the 218 ril.
[LG Optimus 2x] aigaming:
Verry nice thread,i have one question though.

I am using 0521 baseband with matched ril and i am tempted to try other baseband and see can i have even better signal and sound.

How can i BACKUP my current baseband and flash 0725 for instance?Thank you
[LG Optimus 2x] tonyp:
You cannot - and there's no need to do so. Just test different bbs and if you want to go back download 521 from the first post.
[LG Optimus 2x] aigaming:
Fast response,tnx
[LG Optimus 2x] csunny95:
I am using 0725v10d baseband. When I use the getril app. I can see the option of"0725(v10d, Europe);0823(v21d, Canada)". So should I use this option? Is this for 0725 or 0823? Should I use this option?
[LG Optimus 2x] tonyp:
It is for both. It just means that the RIL for 725 and 823 hasn't changed and thus has the same md5 hash. So yes, use it :)
[LG Optimus 2x] csunny95:
ok thx

Thank'you for your precise and very well detailed work Tony, we all love it:good:
[LG Optimus 2x] xStagGx:
Hey guys, which baseband you recommend to use with ICS, based on CM9 ROM?

My problems started when i've upgraded via kdz to last official bb&rom (GB). I've tryed to flash several basebands using smartflash (last was 0327-V20d), but everytime i install maching RIL, radio gets disabled (unable to seek for networks), and in GetRIL basebands becomes "unknown" even if im sure, that im installing the only correct RIL. When i do not update RIL, battery gets drained like hell (100%-50% in 20min)

Halp :<
[LG Optimus 2x] tonyp:
If you read the FAQ properly you'll have your answer.

Hint: You cannot use v20x RILs for Cyanogenmod (except SU660 ones).
[LG Optimus 2x] xStagGx:
I've readed everything, but this one i probably missed. Thx man.,
[LG Optimus 2x] mavEEE:
Hi I've got a question! If I make a backup in cwm and I flash a new Baseband and then install the backup would that work? Or wouldn`t it? I'm using the ChuckNorris ROM based on Cyanogenmod. If that information Helps and I'm Using BB 1035.20110218 and RIL V10b! And i want to update to a newer baseband and a Ril that fits!
[LG Optimus 2x] SREEPRAJAY:
it worked for me perfectly...make a CWM backup, flash a new BB and then restore the nandroid backup.just one point to remind you again.....RIL for the CM 7 based ROM only has to be V10 series and not V20 series....just install the GetRIL app and should be fine....

Hope it helps
[LG Optimus 2x] SREEPRAJAY:
tonyp,

hi mate.....looks like a new LG release....not the ICS :P but V20i....time to check this??? LOOK AT THIS POST

Thanks
[LG Optimus 2x] tonyp:
Hey, thanks for the notice, but BB 327 is already in the OP for a while (thanks to Kostja_V, taken from some russian release).

RIL should be the same MD5 as 313 and 521. if not please report it here and to the makers of LG RIL Version and GetRIL.
[LG Optimus 2x] G1ForFun:
Keep the thread clean and on topic. No need to carry over personal matters into the public eye.
[LG Optimus 2x] Notarzt23:
I have got one quick question. Is it possible that my baseband is the reason i can't call one specific number? It is not a Rom or simcard issue because i tried diffrent roms and also another sim card in my phone :( this sucks pretty hard for me because it is the hotline from my work...
[LG Optimus 2x] tonyp:
Yes that's possible. Some people have reported such problems with SU660 Basebands.
[LG Optimus 2x] Notarzt23:
Ok thank you. I am indeed on a su660 baseband right now because my phone is made in korea. Will try a "normal" one tomorrow.

Edit: problem solved after using a non su660 baseband!

Attention: You cannot use a matching RIL while using a Cyanogenmod-ROM for 313 and 512 BB because there doesn't exists a v10x RIL.

Hello there! I live in finland and at the moment i'm using Miui-2.4.20 rom with its own kernel. Baseband is 0512 and it is working here very well.

I haven't changed my Ril after rom flash so i think it's at v10 euro or something.

I also found App from store called "network signal booster" (by Baca Studio) which edit some files from system with root access and it really boosted my mobile network and radio signal to max.

It was easy to test because i live in area where the signal is poor and i always get slow downloadspeed with any rom/kernel/baseband i have tried but after booster was done signal popped to max and my download speed test was at max as promised by service provider

I hope this will help atleast people living in Finland but also everyone else somehow :P

Sorry my bad english!
[LG Optimus 2x] antec123:
i did remember when the first time i use su660 baseband 0502, it was okay to make phone call but it wasn't okay when i check the ussd code example like *888# to check the balance. that's my experience when flashing su660 baseband.

right now i use 0725 SEA baseband + v10f good combination and never want to flash another baseband or ril :laugh:
[LG Optimus 2x] mas2112:
I'm using CM7 and I've been searching for the right BB RIL combination for quite a while. I found that the SU660 BB 1120 with matching RIL works best for me in Germany (I have a "Made in Korea" phone). The USSD code (*101#) to check my balance works too, although the special German characters don't show up correctly. Otherwise, this is working great for me so far. Battery consumption is ok (1% per hour or more when sleeping), but better than other combinations i have tried.

I have tried 725 BB with matching RIL, but i had a lot of issues with losing network connection.

I have tried 521 BB with RIL 218, which worked well, but it really drained the battery quickly. Other RILs with 521 either didn't work at all, or had network loss problems too.

What works best with CM7 for the rest of you?
[LG Optimus 2x] rexren:
My rom is cm7 nightly 20120722 and baseband is 20120521.

I download a v10R version RIL from Chinese web site and try.

After change the v10R ril and open GetRIL to check its version is 0725(v20d,Asia).

The result is 0725 (v20d,Asia) ril is work on cm7.

We have one more version to chose.:D

Edit: v10r is P993 V10R froyo rom. P993 is like another P990 in China but still update with froyo rom til now.

So P993 ril may be the latest froyo ril for us.

Go ahead and create one ;)

I have no idea about the P999 so no, not from me.
[LG Optimus 2x] DsturbD:
gotcha

where do you get the fls files? are they in the in kdz files? and would it be safe to assume that the same steps here would work on a P999 phone?
[LG Optimus 2x] tonyp:
As I said, I have absolutely no idea about the P999, can't help you there. I think it is similiar, but you have to check and ask that at the G2x forum.

The fls files are mostly from LG, they ship zip files which contain a *.bin and *.fls file. I collected them from all over the forum and brought it here together in one thread.

You can extract a baseband out of kdz files (at least for the P990) with LGExtract. It will generate four different fls files then, but that's not really a problem, you can flash them as well.
[LG Optimus 2x] DsturbD:
sounds easy enough. i will give it a try. ever since i updated the baseband on my g2x i've hated it and can't really find anything that makes it easy to downgrade

thanks for all you do on XDA!
[LG Optimus 2x] thorstenhirsch:
Here's my BB/RIL history:

BB 0405 (that's what my P990 shipped with)

- every RIL I tried worked

- always & everywhere signal

- but low bandwidth, bad quality

BB 0313

- RIL 0313: does not work*

- RIL 1120: perfect for data (high bandwidth), but phone does not work (it seemed as if the microphone was switched off when picking up the phone and switched on when hanging up)

- RIL 0725 (Europe, leak): does not work*

- RIL 0725 V20q: does not work*

- RIL 0405: does not work*

- RIL 0218: data works (not very good), phone works (might be better than 0405/0405)

- RIL 0823: data works better, phone works fine ...I think this combination is pretty good

* = phone did not ask for pin, so it could not access the sim at all (?)

edit: list updated
[LG Optimus 2x] darryd:
which one 0725 you used? did you try 0725 from V20r rom? 4 files baseband...
[LG Optimus 2x] thorstenhirsch:
No, it was one of those with "leak, Europe". So it was V20c, V20e, or V20j. I don't remember.

edit: Now I also tried 0725 V20q, which is said to be more or less the same as V20r, but it does not work.

[LG Optimus 2x] ronniet:
I keep getting 'Incompatible handset' whenever I reboot (no matter which ROM I use). Installed GetRIL and with my baseband (1035.21_20110405) I can match it with a 0405 RIL (Spain/ASIA) and that keeps GetIRL happy. But I still get the 'incompatible handset' message on reboot. Any ideas? :(

Since 0725 is the most popular baseband, I would stick to it. Try other RILs. There are V10 RILs and V20 RILs for 0725 baseband. I would try V10.

You have to test the different basebands for yourself, there's none that works for all.

Everyone has different experiences with different BBs.

I pushed the Basebands to another server to guarantee you an uptime of almost 100%.

Now we got the following three hosts:

battery is ok.

is some rare cases there is no network coverage after restart - happens once in week or so.

there is one problem with bt - bt does not see my se bt headset - this might be also roms/kernels problem, because connection with PC is fine.

so far this looks best option for me, because all other bb have sound quality problems, wifi and 3g problems.

in Europe ....try the latest V20S or V20Q Baseband....if you are usinf the CM based ROM, then your RIL has to be V10 series...check for the good one with GetRIL app.I use the V20C Russian BB/RIL which works great for me

suitable BB/RIL combination will give a good battery performance too
