[LG Optimus 2x] theevilworm:
Thank you tonyp, this is just plain awesome!

I wish I had this guide two weeks ago when I started messing around with BBs and RILs. Could have saved me from a lot of stress. I couldn't find any guide to basebands where all knowledge was collected. Was really hard to gather all the information I needed. Now with your thread new users can easily understand what BBs and RILs are. Great job!

I just hope you will keep this thread up to date.

I use BB313/RIL0128 and owains CM9 build 58 at the moment but have used other BB/RIL combinations like 313/313 (big problems), 405/405 (stock, no problems), 725/725 (extreme battery drain) and 420/1120 (no noticeable difference to current combo).

I still experience fast battery drain: Today morning I surfed the web for about 2 hours and lost 35% battery!

When I unplug my phone from the charger at 100% and leave it in standby during the night I have about 80% left next morning.

Is this normal? What BB would you recommend for better battery life?
[LG Optimus 2x] tonyp:
I don't really think that another BB/RIL combination will help you here. From my experience another BB doesn't make a big difference (expect some odd combinations of BB/RIL/hardware components which will have a huge drain). I tried a lot of Basebands and all of them had a pretty similar battery time (stilll havent tested 0420).

You should look for wakelocks (use BetterBatteryStats from market or free in xda) and other misbehaving apps.

But 3G and screen on will always have a huge battery consumption.
[LG Optimus 2x] Pete Rask:
I'd recommend 420 + ril. In standby it drops around 0,5% per hour on 2G + data (Edge). At least the best I had (Owain 70, Harsh 2205).
[LG Optimus 2x] R0B3RTF1SH3R:
same here.
[LG Optimus 2x] vadonka:
hey tonyp :)

you have a very nice thread here.

just a little correction

this baseband:

0530-V10t-Baseband	MD5: e0a940f155be6cc54cd09f564517410f

its SU660 based too.
[LG Optimus 2x] salisbury_steak:
Great idea on the poll Tonyp. I'm predicting that the 0725 numbers might get bloated though, as I think LG used that name for at least three actual Froyo and GB Baseband packages last year.

In any case, it's still very helpful to look at. Kudos. :)
[LG Optimus 2x] aragorn7:
Couldn't have said it better myself. I agree whole-heartedly!

THANKS TONYP!!!
[LG Optimus 2x] tonyp:
Thank you for the kind words :)

I considered to create different options between the 725 releases but chose not to do so at it might create some confusion and not all people now which particular version they're on.

A couple people I wrote with told me that they didn't notice differences between the 725 BBs they used. I know that LG changed some things, but apperantly not much. Maybe some people who experimented more with the BBs can add their point of view to this.
[LG Optimus 2x] salisbury_steak:
I agree. In a public survey like this, Id rather go for ease of use, rather than confuse the respondents into not taking the survey at all.

And you're welcome. You totally deserve it.

[LG Optimus 2x] R0B3RTF1SH3R:
actualy thats something i would like to know. which 0725 BB to use.

it was default on this fone and now im using froyo from topogigi. i would like to know the best 725 BB to use =D
[LG Optimus 2x] slebit:
I use v10d of 0725. It's the best that I have used. Good battery life and decent signal strength.
[LG Optimus 2x] ermacwins:
Thanks for this. Looks like I will be flashing to 725 BB
[LG Optimus 2x] R0B3RTF1SH3R:
anyone using v10d in new zealand ok? or is that the thing.

if 725 works in my country. technically all 725's rils' should work.

thats strange i flashed one 725 RIL and on reboot, it said 218 and fail!!
[LG Optimus 2x] lipisak:
I'm not sure if I wrote it here, but two weeks ago I flashed 420Bb with 420 ril from getril. I own o2x Made in Korea. Using owain 70 right now And summary:

Much better sound

no data dropouts

No call dropouts

Battery +/- 36h.

Not nad right?

Nice! Which baseband were you on before? 1120?

I'm asking to see if I should make the jump too. I have been hesitant because of needing to back up the internal SD card, which seemed like a hassle.
[LG Optimus 2x] Sheppie:
What apps are you using, do you use facebook/whatsapp/google+ etc. a lot?

The 36hrs are still nice thou :)
[LG Optimus 2x] lipisak:
I were on 218 the Basic one from factory.

OK using FB, G+, taptalk, news application, Apollo player, stock browser, taptalk.... thats's the most drainers in my case....

there are also lots of apps and games which i use.

Hope it Will help somehow.

And few more things:

Display bright: auto

3g: half of time on

WiFi: the rest of tíme on

Music: ways to and from work let's say 3h.

GPS used when needed

Synchro on when on WiFi.

Best L.

Wow the voters exploded after I asked in owains and temaseks thread - from ~50 to ~150 :D

Maybe I should ask for voters in other threads as well hehe

I plan to close the poll after some time (in 1-2 weeks) and reopen a new one in a couple month somewhen around August - November. Then we can see how Baseband usage changes over time.

I updated the second post and now recommend v725 v10d. I searched in some threads and it seems that many people are very satisfied with.

And I'll flash 420 BB now - there're a lot of people who tell about a better battery life. Never had any battery improvment and I tried lots of basebands - but maybe LG did finally address some drain issues (3G?).
[LG Optimus 2x] SuperSkill:
Depends on region, but yes, I used 20q in Norway, I think stefan used it in Austria though it was released in Italy. Many used 20S in the end of GB days. I'll upload as soon as i get the time :)

[LG Optimus 2x] tonyp:
I just uploaded 725 v20r BB.

Thanks for the notice nicorb.
[LG Optimus 2x] Ph03nix95:
I am currently running 0725 BB with matching RIL, and I seem to get good reception most of the time, good call reception etc but then sometimes I just have no reception(Although it seems to usually come back in ~5mins or after a reboot). Should I try a change of BB or could this be due to another problem?
[LG Optimus 2x] tomislav177:
I have 420bb with his ril and latest vadonka kernel. Battery after half day is on 75% which is great. So far the best baseband.
[LG Optimus 2x] Infy_AsiX:
I've was on 218 since CM7 originally and its dropped on me once every so often. I used 405 compatible ril which improved it without changing baseband. Most annoying is when it drops and doesn't reconnect. I put tasker to detect a drop and set aeroplane on and off. It helps but sometimes you just have to wait half a minute or so. Definitely annoying and no doubt bad on battery.

A couple of days ago it started happening more often. So I went through almost all the basebands, su660 and the ones with multiple rils to test. I'm on a made in Korea p990.

I found they all generally work the same for dropping. Noticed call improvement getting off 218. All su660 basebands and 313 don't receive calls although having reception and the caller gets a successful dial tone. All the rils seem to work the same so far even the su660.

I wish I could stop the dropping but looks like I'm stuck with it. Phone faulty probably. As long as it doesn't happen too often or in calls i can live.

I find I can replicate the drop easily by being in 2G with full reception and placing it somewhere it loses just one bar, then it drops.

I'm settling with 813 as a later release and v10c as i've read someone document it scales cpu immediately.
[LG Optimus 2x] HerrKuk:
I think it might be a GB bug

I friend had it on his SE Arc stock GB, i had it on CM7 and a few of my coworkers with stock GB. Not much to do i guess, perhaps CM9?
[LG Optimus 2x] tonyp:
Yeah I would try out another ROM, too.

For some people it seems that turning off automatic time helps (use Clocksync from the market instead).

You could try to logcat the signal drop (google for instructions!) - but I'm no expert in reading logcat, we would need someone else to analyze the log. pastime or owain for example.
[LG Optimus 2x] Infy_AsiX:
On temasek cm7. Auto time off. Noticed in the past auto did cause drops and disabling would bring signal immediately. I still use it just to regain time when needed and unset. Clocksync just to detect off time, no net required and no non sync bug I hear.

GB signal bugs? First I've heard. I can replicate it quite easily. Placing on bed side table where a large mirror directly blocks the direction to tower. That little disturbance in signal makes it lose out completely.

Trying 622 with with v10c now with better luck, touch wood. I have a feeling v10 might suit cm7 better
[LG Optimus 2x] tonyp:
Just in case vadonkas kernel has a downtime I'd like to set up another mirror.

If there's anyone with a server and willing to do so please contact me :)

I don't need server access, feel free to just copy the files from vadonkas server.
[LG Optimus 2x] Infy_AsiX:
622 with matching v10c has fixed my constant dropping issue. I only get the occasional random drop now. Using no signal alert from the play store to notify when it drops and regains signal is very useful

EDIT: doh I should have read the FAQ more carefully.

As per the info only those certain RILs work on CM7. I think a problem I was getting was using a wrong RIL, screwing the baseband and using plane mode to try and reset it but it seemingly didn't and gave me those issues. I find SU660 basebands dont really work for me, i'll get very low signal on 2G where it's normally full. 823 wouldn't connect for me. 725 matching froyo ril is probably my best bet. Although su660 RILs do work for me so i'm trying 420 with it.
[LG Optimus 2x] vadonka:
seriously.. need to stick this thread.

write a message to the moderators :)
[LG Optimus 2x] tomislav177:

thanks for the excellent tutorial,thread which is a one stop thread of BB related things.

can you please check the V20r? It gives me a bad link.tried it with other browser too. I got the file alternatively.

Thanks
[LG Optimus 2x] tonyp:
Thanks for the notice, I had something missing in the link. That link list is a pain to manage, especially from the phone, but I think I corrected it hehe

The file was already on the server, which you can browse for the Basebands without visiting xda:

Thanks again to vadonka for his hosting.
[LG Optimus 2x] speedme:
I'm not using BB 420 with RIL 218 since 1 day and it really improved in-call quality.

About battery drain I can't tell yet, too soon.

And I have Owain's excellent CM9 ROM installed with default Harsh kernel.
[LG Optimus 2x] aragorn7:
Has anyone tried switching from BB 1120 to BB 0420? If so, have you noticed an improvement in call quality?

Thanks in advance!
[LG Optimus 2x] -SONNY-:
Anybody got a phone which is manufactured in a different country than Korea?

I ask because i never saw one.
[LG Optimus 2x] mironiko:
Anybody from 0824 to 0420? Any differencies? Call and signal quality and battery life are what interests me... :)

Optimus 2X The Lightning
[LG Optimus 2x] tonyp:
Many people posted that their battery life is better with 0420.

I'm currently testing 0420 and cannot confirm that, I'd say it's about the same for me, maybe slightly better.

But call & signal quality are perfect.

I used 1120 before - didn't see any differences to 0824 there. From my current experience I think that 824, 1120 and 0420 are pretty similar - I will stick to 0420, can't harm to use the newest one (and it's already flashed).

Korean build P990 here.
[LG Optimus 2x] SREEPRAJAY:
is your device a korean make?

I would like to try it too...just to confirm

[LG Optimus 2x] Infy_AsiX:

Also furthering my tale of signal questing. su660 ril eventually stopped taking calls like their baseband counterparts.
[LG Optimus 2x] aragorn7:
Ah, never mind. I found an answer here

What do you think about updating the guide based on these posts?
[LG Optimus 2x] tiithe:
Side note.. if you are using BB 0420 with CM9 and you get several network disconnects (No service in notifications) after a call or WLAN to 3G switch, then test to switch automatic time and timezone off.

Before i had No service after any second or third call .. now after automatic time off is all working flawless.
[LG Optimus 2x] aragorn7:
This did it for me!! After struggling with this for a week, you helped me find the solution!! Thanks so much TIITHE!!!!! :)

Because of it all, I at least got to learn a lot about BB/RIL in the process, thanks to the many good folks here at XDA. hehe :D
[LG Optimus 2x] SREEPRAJAY:
I remember seeing this instruction on Temasek's thread about a few BBs....it was for CM7, well it must be the same for CM9....

Thank you, knowing that the signal&call quality are solid makes me eager enough to change from 0824, even 'though battery life seems the same - I am happy with it even now, being on temasek's ROM and OC kernel.

Will post my findings, after I flash the 0420 BB... ;)

Optimus 2X The Lightning
[LG Optimus 2x] el_charlie:
I'd like to ask a question:

What about the 3G frequency bands when using a SU660 Baseband???

I have flashed 824 and now 420 and I get signal but only EDGE, no HSDPA or UMTS.

My operator uses 900 MHz for both 2G and 3G but when using a SU660 Baseband I only get EDGE. Almost all other P990 baseband gives me HSDPA.

My phone is a Made in Korea P990. Can anyone comment on that??

Cheers!
[LG Optimus 2x] tonyp:
It does work for me, I guess you just can't use su660 basebands then :/
[LG Optimus 2x] el_charlie:
I guess that's not a proper answer, but thanks anyway.

Which are your carrier's frequency bands for 2G and 3G???? Is your phone made in Korea??

Cheers!
[LG Optimus 2x] tonyp:
Sorry for my short (and maybe not "proper") answer, I was on the run and replied from the phone.

Here it is 900/2100 I think. Could be a reason.

I got a Korean P990.

What I meant with "you can't use it": When I wrote the thread about fixing static noise issues with 824 I got many replies and PMs from people who wanted to try 824 and it just didn't work for them, with no apparent similarities. It seems like the devices differ that much that some can't use SU660 BBs at all (which we can't complain about - they aren't made for us). Even Korean ones.

Carriers and frequencies could be a reason, too.
[LG Optimus 2x] el_charlie:
Yes, the frequencies are the important part.

With 824 and now 420, I could get full 2G (EDGE) signal. But the phone never tried to get HSDPA. My carrier does use 900MHz for both 2G and 3G.

Maybe the SU660 basebands are for 1900/2100 3G.

Back in the days I had a Motorola Milestone (International version of the Droid) I remember I had to set a correct RIL for my carrier because otherwise the phone would only work in 2G. That's because most ROMs I flashed were for the European model and I had the Latin American model which used 850/1900 (I had a different carrier then).

I'd like to suggest to every user tell their experiences and specify the bands of their carriers. If they don't know, a simple wikipedia lookup would tell that.

Cheers!
[LG Optimus 2x] Infy_AsiX:
Indeed it varies. In my case it's the 2G band on the su660 baseband that suffers. My carrier uses 900 1800 2G and 900 2100 3G
[LG Optimus 2x] -SONNY-:

Will I go back to stock LG rom by doing this installation? ??will I need to root again ?????
[LG Optimus 2x] SREEPRAJAY:
just check V20H (same as V20Q as indicated by some)which is the latest BB for India. You have to just flash the BB seperately and use a custom ROM whichever you want...no need to root again...just backup your apps and data...

Use this excellent tutorial in the opening post and posts by tonyp..

I would suggest you to flash V20Q or V20C russian BB...I am using V20C and have no issues mate

wanted to tell you....my phone has the Made in Korea label under the battery but when i tried to flash the 420BB i had terrible results...so i changed to V20C. Just to keep you informed about BB 420...

In a lighter note: In India, 420 means a cheat...as the law no 420 deals with the cheats, robbers and unlawful elements...:D:p
[LG Optimus 2x] tonyp:
Thank you. I just wanted to give something usefull back to this great community and I figured a "complete" baseband thread is missing as people generally have had many questions related to basebands.

I do have software engineering skills and would love to help with the "real" development, but I just don't have the time. This is the next best thing which came in mind.

And I do appreciate these kinds of reports.
