Strange problem with RIL and GB custom ROMs

I have Froyo v10d baseband and after flashing any custom rom when i try to match ril with baseband (with GetRIL) all goes wrong. Well not all but crucial thing. After reboot there`s no more screen with dialpad to enter simcard PIN so I cant get network signal. I`ve tried all 3 Django`s rom, 2 of Gueste and new Thanatos.
Sorry about english, I hope i`ve been clear enough.

Sorry guys I forgot to say that I install v10d ril whit GetRIL. After reboot there is as on attached pics.

Hi,
0823 BB is sometimes very problematic, and not suitable for everybody (cf second image).
I think that if you want to use latest custom roms, and especially v20o, you'd better flash v20m baseband, which has the same numeric name as yours but is clearly not the same. I personnally used v20l baseband without big problem, and I just upgraded to v20m one.
I just read that v20m baseband is not compatible with Cyanogenmod (only Froyo BB must be used), but flashing a BB is just a 5 minutes work.
You have all the BB you want in the Great Temasek shared folder here (in optimus p990 folder): http://www.mediafire.com/temasek
For V20m, you have for .fls files to flash, beginning with biggest file and following with decreasing size.
There is a how to text file in archive.

It's the same issue I had when trying to use GB RIL with CM7 (latest KANG).
I have the same baseband you have, and it works well with RIL 725 v10d.

With CM7 Kangs everything works fine.
So when I flash custom GB ROM can I leave RIL from him as on first attached pic 0725 v20l? Somewhere I read that different RIL cause more battery drain.

Why not simply try and test? can't say it for you, and changing Ril is fast...

I had the same issue.
I currently have v20M flashed through KDZ updater, so I have 725 v20m BB and I'm afraid to have radio problems with CM7.
I tried using V20l RIL and didn't work, but using v10d 725 RIL worked but I reverted to stock rom for now because maybe I'll have some problems.
If you tell me it's ok to use v10d 725 RIL I'll try CM7 again.
Cheers!

Its not just ok to use v10d 725 RIL, it is a must to use it. Why? CM7 isn't compatible with GB RIL. You can use GB BB but not GB RIL. It will cause unknown baseband if u use GB RIL.

No best combo. U have to try out yourself.

Hello, I downloaded the V20M-Baseband.zip but there is no text to explain how to flash it.
Can anyone help?
Thanks

Search in dev section there are threads about this.

[Q]Unstable 3G

Hi,
I have managed to flash CM7 on my optimus 2x.
Much better than the stock rom.
However I have an anoying issue, my 3G connection is very unstable. When I use a speedtest or just surf on the internet, my phone automatically goes back to 2G (Edge). Then after a few seconds the 3G connection is back. This also happens in places where I have full 3G reception. Also I have noticed that the download speeds are much lower than with my old phone. Could this be a problem with the RIL or the baseband. Or maybe should I try tamosek's kang build ?
I have bb 725 with RIL v20l.
Thx for your help

Hi there,
If you have stable CM7 I would rather recommend Temasek's Kang because it is better than the stable version or nightlies. Temasek put new or other things in the rom those are referred as cherry-picks. So a KANG is actually an improved CM stable ROM. I would also recommend Vadonka's kernel ETaNa-REV1 which will increase your battery life a lot and can speed up your phone with ram hacks. With the 3G problem you should try GetRIL and download your recommended RIL combination.
You do not need Temasek's Kang or Vadonka's kernel to fix your 3G problem; it’s just a suggestion
Good Luck

Thanx for your answer, I will certainly give Temasek's Kang or Vadonka's kernel a try Is the combination of Vadonkas kernel and Temaseks rom more stable than CM7 and stock kernel ?
I have already downloaded Getril and made sure that bb and rill match. But it doesn't seem to be solving my problems

I remember that the BB and matching RIL for the CM7 or even Temasek's Kang is 218 and not the one you have mentioned.
Some also use 824 BB
maybe the change of BB would make the difference

So you say I have to use nonmatching RIL and BB ? I'd rather not change the baseband since sound quality during calls is fine

u have to use the matching BB and RIL for sure....but , the combo of BB and RIL makes the communication perfect....wifi,voice calls,sound quality, 3G and so on

you may update your BB and ril
e.g. v20q BB& v10d ril is good for my phone
however, the best combination just depend on where you live
besides, I suggest you change the rom. some roms that are overclocked may also lead to connection problem

[Q] RIL and BB for Philippines

Mabuhay,
It's just recently that I'm having problems getting a GPS lock, signal loss, and poor voice quality with A.R. 2.0 which is still based on Temasek's kang 67. Get RIL app says that my RIL (0218 V10b, Europe) and BB (1035.21_20110725) doesn't match.
Can anyone recommend a RIL that will match my BB with the best battery life here in PH or Vice-versa? I don't mind changing BB if it's really necessary.

Try HK rils or any Asian RIL

Just go with v20l bb. Look for it in development threads.
Basebands work internationally.

@dhogthag
What BB/RIL combination are you using?
I just flashed to CM7.2 but can't get 3G signal and data connection anymore in Globe ph network

First thing would be to use a matching RIL as there exists one for your 725BB.
This would be the 725 v10d RIL in GetRIL.
Second: read the FAQ here: LG P990 Complete Baseband Overview Thread

upgrading baseband

Hi,
was just about to upgrade the baseband on my 2x, but for some reason it's not working.
My old baseband was 725 and wanted to try BASEBAND 1120 - P990 ( SU660 Porting )
I downloaded SmartFlashTool_P990.exe + drivers and installed the 4 files in order from biggest to smallest.
When the LG logo started to flash (after each SW FLASH install), i removed and reattached to cable+"volume down" to install next file.
R375_SIC.fls
AENEAS_FW.fls
slb.fls
psi.fls
When I was done with the baseband flash, I installed lasted RC of [CM9][ROM][MAR07] Nova HD Plus.
Checked "about phone" and it still say I got baseband version 725
what went wrong?

If you read the first post carefully, you will find that the author describes that he has compiled with his old archive....but that has to be 823 normally. Anyway, if your communications and other radio related stuff is working alright....why think about the information in the BB column.

thanks, didn't notice that.
Still don't know why I was not able to upgrade to 823

This is not true, I think. It just states this for the update script in clockworkmod. The about phone should state something like 20111120

?
What does baseband do?

by changing your baseband you can possibly get better signal, better incall voice sound, but if you don;t suffer from any of those problems than don;t change it

bb
IF your BB and RIL mach, then you might get better batterylife.
Check your stock BB and ril. it must work best

And to match you RIL, there's a great app called GetRil .

Baseband and ROMs
Hi,
I have 725 baseband. Can I flash CM ROM or MIUI ROM?
Should I have a specific baseband before I flash a different ROM?

725 seems to be the best for cm 9 (at least for me ) , so i would keep it

No you don't, in some case the author of ROM specify the better BB, also you can use Get Ril to match ril and bb, this is usefull for battery life and best signal too

[Q] About Baseband and RIL

Hi
i have the 0725 baseband on my phone. As i understand, to archieve the best batterylife is to match the RIL with the baseband. I just checked my battery consumption and the signal is almost never green. To compare with phones from within the household, a wildfire S, Arc S and Ray all have a green bar.
So, i tried to change the RIL to the recommended 0725 (V10D Europe). My 2X grants permission, reboots, but the RIL is still the CM7 stock 0218.
What should i do? What am i doing wrong? Is it not possible to change the RIL?
Btw, Temasek Kang with vadonka kernel. I live in Denmark (Europe )

I think you are experiencing the /system r/w bug that's being discussed in the thread of the etana kernel, check it out.
Cheers

So thats it! Thank !
Is there any other way to change the RIL?

You can put another kernel for cm7 in there (like a older one) use getril then reflash the latest kernel or wait for a fix.
Cheers

Makes sense.
Thanks for the help
