Doubt with frequencies

Hi,

I am considering in buying a P990, but I have found lots of confusing information. Some sites post baseband frequencies for WCDMA as 850/1900/2100, and other post 900 / 2100. I am a bit confused, I need a phone that works with 850/1900.

I know that HTC phones don't allow frequency changes, some Samsung models can be switched depending on the radio baseband that you install. How is this with this phone? Do the supported WCDMA frequencies depend on the baseband or is it the hardware?

Regards
[LG Optimus 2x] TrymHansen:
Hardware. For WCDMA 850 you need either a P990h or P990hN or a P999 (G2X). Regular P990 does not support the 850 band.
[LG Optimus 2x] LarsPT:
Does that mean my P990 will not work in the united states?
[LG Optimus 2x] svein01:
Your p990 will work in the us. Mine did. The bigger question is: LG is already late on their upgrades and have already announced they are going back on their stated promise to upgrade this device's OS to ICS, and Google is already on the second update to Jelly Bean. This device is dead in official terms, unless you're prepared to rely on unofficial updates. The OS that your phone comes with is 18 months old by now.

Anyone tested if the RIL from the V30a works on CM10? I know we were told not to touch it, but has anyone tried it on CM10?

Hi which Baseband is used by Ricardo Cerqueira for CM7/CM9?

LGP990AT-00-V10b-EUR-XX-MAR-09-2011+0_CP

LGP990AT-00-V10b-NEU-XXX-APR-05-2011+0_CP

LGP990AT-00-V10a-525-01-MAR-08-2011+0_CP

Are there any relevant differences at all?
[LG Optimus 2x] tonyp:
RC uses 218 BB/RIL.

There are differences:

LGP990AT-00-V10b-EUR-XX-MAR-09-2011+0_CP

this is the 218BB from the first post

LGP990AT-00-V10b-NEU-XXX-APR-05-2011+0_CP

this is the 0405BB from the first post

LGP990AT-00-V10a-525-01-MAR-08-2011+0_CP

Don't flash this as ROM Manager will recognize your phone as G2X.

I guess this is 218 G2X BB.
[LG Optimus 2x] gtr-kir:
It's impossible to be for g2x, because it is for LGP990. And it consist 0218 bb
[LG Optimus 2x] tonyp:
Okay, I just found several posts for this bb where the ROM Manager would recognize their device as G2x. But I have no clue about G2x basebands :D
[LG Optimus 2x] tetsuo55:
Is there any way to flash a baseband from CWM?

My phone does not make a usb connection on any OS or system. (not even in download mode or in recovery through mount usb)
[LG Optimus 2x] tonyp:
Unfortunately, no there isn't.

In the third post are two different driver packages linked, you could try if one of them does work for you.

If not you have to stick to your BB (or send it to LG if you still have warranty).
[LG Optimus 2x] sibbor:
tonyp - GREAT POST!

tonyp, I've added 'thanks' to your posts. Great job there! Also made a few changes to the GetRIL database. To my users: hit the update button within GetRIL to get hold on the latest database.

I would also like to notify all my users that I need help with beta testing of an upcoming version of GetRIL, 0.8.3. It looks like a minor version bump, but it's just the tip of the iceberg. I've made a lot of work to the core of the app. Therefore I'd like to see that the stability is good before publishing this version on Google Play Store.

If you'd like to help me out head over to the GetRIL there @ XDA and install the GetRIL 0.8.3 beta APK from the first post. Get back to me with reports in that thread or via PM.

Thank you!

Again tonyp - great thread!
[LG Optimus 2x] R0B3RTF1SH3R:
hi, i found my p990 is a korean one. and i tried your advice. just starting with a su660, ril.

1120 v20j, so far the battery doesnt seem to go down 1% per minute while using it. which is great.

my question is. which BB would you recommend flashing to. with a korean model?

and a strange thing. its better to have it on 3g mode because it maintains a stronger signal. (2g mode) you think would save batt. but its obviously fluctuating alot making the fone try to get a better signal. resulting in what i guess is more battery drain? is that sounding right?

---------- Post added at 06:17 AM ---------- Previous post was at 06:09 AM ----------

ive notices a problem with getril. when i install a ril using it. if its a (broken ril mismatch) the program reports it being mismatched, then it says it has UNKOWN BASEBAND, when i restart my fone to check if the signal/wifi etc works. if it doesnt i load up getril again and then find that the installed RIL is a different number/name from the one i selected before reboot. (its not doing it all the time) but i noticed it most of the time there was a mismatch.. is this fixed in 0.8.3
[LG Optimus 2x] tonyp:
1.) I'm using 1120 BB/RIL with a korean model myself currently. But as I said in the FAQ, unfortunately every phone is different. And I haven't tested the new 0420, yet.

2.) I don't exactly get your question. "2G only" will save you alot battery because 3G battery consumption is higher. I'm using "Toggle 2G/3G" to automatically change to 2G when screen is off.

3.) Please report your issues with GetRIL in the appropiate thread

@sibbor: Thanks for the kind words :)
[LG Optimus 2x] rototrol:
I actually thought about this some time ago: the only problem with ALL the P990 BBs is the voice quality. I wonder if it is in any way possible to patch a P990 BB to disable the in-call sound boost we all hate; I remember that somewhere in the hidden service menu there's an option about this, but it turns out it isn't possible to modify its value. Unfortunately I can't provide further details 'cause I'm using CM7 and as such I don't have access to the service menu anymore.

Does anyone know which language the BBs are written in? Would it be possible to reverse engineer them? Quite fascinating subject, I say! :)
[LG Optimus 2x] dabl8:
Would it be possible to give more location information in the baseband files? I am trying to fix my sisters phone but she is in UK on T-Mobile so any clues are welcome.
[LG Optimus 2x] dabl8:

thanks for your reply tonyp. im trying the new 420. cause u know. its 420 man!!!!. so far so good. only one ril. so u cant go wrong right.. =D
[LG Optimus 2x] R0B3RTF1SH3R:
now standby and idle screen of time is excellent, 10% in 2 hours. compared to before roughtly 10% in 1 hour.

i guess this is the best combo for me (in new zealand) so far. on korean p990,

havnt tried 1120 or 313

Will smart flash become compatible with ics in the future. It would be a lot more practical not to have to go back to gb to update baseband. I guess the other way would be to make basebands compatible with nv flash. Interested to hear thoughts
[LG Optimus 2x] spyrosk:
Why do you say that smartflash is not compatible with ICS?

I was on Topogigi's 28G ROM and I flashed V30A (bin and fls files) with smartflash just fine, without going back to GB first.

Edit:

I read the OP and now I see why you said that. If I remember correctly, when that update in OP was written, there was another unlocked ICS bootloader (with a white unlocked padlock as logo) which had a problem with smartflash. It didn't let you go in smartflash mode at all. Maybe that's why it says "only works with the old bootloader".

@TonyP: I think that the 3rd post should be updated.
[LG Optimus 2x] ToesNZ:
Thanks for your advice and have read what others have had to say today in Topogigi's ICS thread, have successfully updated two 2x phones from 28g baseband to 30a with no issues. I made a backup before doing the first phone in case i had issues with loosing data but had no issues at all. easy as!
[LG Optimus 2x] mr_dvdj:
I confirm i did it with no issues several times, just nandroid backup, flash by smarflash and restore form CWM. As i worte on the other post the only strange thing i have noticed it is a "time out error" while disconnecting device at the end of flashing procedure than smartflash says it cannot sync something, i can't remember. After this phone boot normally and calls, signal, data and wifi are working greatly!

I wrote this here too cause it can be useful for others, I had to flash several BBs cause i had a problem with WiFi but i discovered it wasn't due to BB, it was (apparently) due to an application (Viber) restore from CM10 made with titanium backup.After uninstalling and re-installing it from google play everything works fine!
[LG Optimus 2x] moraize:
People I need help.

First, sorry if its on the wrong post, if it is, so let me know and I´ll change that.

I live in Brazil and since I bought Optimus 2x( 10 months ago) 3g connection was VERY bad, I generally only conect to dataservices on EDGE, only very few times The fone got a 3g or Hspda conection, i Thought it was operator related not optimus related.

Last Week, I changed the operator and exactly tha same occurs...

So I observed My wife´s phone( sony Erycsson Neo V), and for my surprise it ALWAYS gives me a HDSPDA connection, at the SAME place...

When I conect on H, On both phones I get about 3Mb/s on speedtest app.

On my phone when I´m on Edge, I get onle 40Kb/s.

My question is could it be BB/RIL related ??

or a malfuncion on my optimus ?

And more, I get many "no signal conections" and at this moment My wife´s phone is full of signal for my complete angry !!

So, any idea to help me guys ?

Thanks .
[LG Optimus 2x] optimusG:
These radio problems could be caused by wrong combination of BB and RIL. Could you please tell us which BB, RIL and ROM version does your phone have...?
[LG Optimus 2x] moraize:
OK. Now at this moment I´m using Gueste Goodbye 2.0R( based on Stock rom ) from Stefan Gündhör.

I´m using the BB/Ril combination recomended By him : BB: 0725 20L; RIL : 0725 20J.

But, I´ve lready tryed 0218/0218 ; 0725 20R/0725 V20R, and the SAME happens...

Before this rom I was with Gueste 3.8 ( hybrid version). So installed STOCK LG ROM 2.3.4( 20R).

But ALWAY the same. The majority of time I have E on display not H. If I change to WCDMA only I get no signal( sony erycsson all the time besides it on H, same operator).

The picture shows the great difference when I connect on H and E, E gives me a VERY slow speed, and H is much faster.

I Just wanted to be sure if its a MAlfuncion on MY phone or if Optimus really has problems with that, and If could be done something to solve that ...

This way its impossible to keep this phone...

Thanks.
[LG Optimus 2x] LarsPT:
I would try some other basebands before giving up if I were you. Try some more recent, like 0521, and before restoring your backup use your phone a little (browse some pages or download some apps) with a fresh wipe to see how it behaves.
[LG Optimus 2x] moraize:
0725 is older than 0524 ?

So, Yes I´ll try, but I´ve already tryed a lot of BB/Ril and can´t see any change. I Always try data connections before reinstaling apps with titanium backup. The problem is always there on the very first use...

A friend of mine has optimus and today he was using Django manouche ICS rom, and he told me he has the same problema of Poor signal on Optimus, and before he had a Milestone and it was AMazing the signal intensity on that model...After he changed to optimus he had this problem either, so I suspect that at least with some units, we have this problema and it seems to be hardware related.

I say again, My wife´s Sony erycsson Neo V , besides my phone has ALWAYS a H connection and VERY FAST...we had already swapped the operator chips and her´s keep on H and mine on E...
[LG Optimus 2x] LarsPT:
Yes, 0521 is from 2012 and 0725 is from 2011 :)

My phone also came with 0725 (I think it's the most common) and my reception got a lot better when I flashed 0521. Now I'm on P990 v30a and it's also very good (I don't think it's better than 0521, but at least it's not worse).

So, before giving up, definitely give 0521 a try!
[LG Optimus 2x] moraize:
Ok, I´ll Try, BUT, only today I tested :

TO put the original rom( 20a) = same problem

I put 30A + ICS ROM + RIL 30A = same problem...

but, ok, I´ll Try 0521 :)

thanks...
[LG Optimus 2x] mr_dvdj:
I know with new ICS roms "made in korea" problem should be solved, but with mine phone i've got much better call quality and signal with Su660 derived basebands in stead of the one indicated by Topo and Stephan. You could try with those.
[LG Optimus 2x] moraize:
Ok, I'll Try SU660, I used them when testing CM10, but at that time I wan't concerned to internet connection...

0521 = installed and the SAME problem... Almost all the time I only connect on GSM network :(

and I i'm having lot's of "No signal" at all...(with all BB tested)

And it's related to optimus, signal is great...

It's very strange, because when I'm able to connect on Hspda the speed is VERY good...

Thanks
[LG Optimus 2x] LarsPT:
Maybe you have a defective unit after all :(
[LG Optimus 2x] rockyy:
well i installed BB V30A and the RIL but my signal seems to be bad 1-2 Bars and not EDGE sometimes... I wanted to check with GetRIL if everything is okay and GetRIL tells me my device is not supported oO [P990]

i live in germany and im using o2 if here is someone and can tell me a good ril and bb.. i came from 1035

V30A = 1035.21_20123011 ? right?
[LG Optimus 2x] vkk178:
Get RIL doesn't work yet for Jb& ICS. Use default ril and do not install RIL using getril. As far as baseband goes u need to try . I'm am on 521 and works fine for me.

Brain waved from my O2x using XDA app
[LG Optimus 2x] moraize:
Man, its very strange. Today I went to a confraternization from my job, and I met a friend of mine who has the same model, So I told him, let´s show you that when I select "WCDMA ONLY" I get no signal at all, I did that and ...A beatifull H on display, and it didn´t disapeared in all event, 6 hours after when I was going back home, I lost the signal. And it didn´t came back until I changed to " WCDMA/GSM" But it came as Edge...

strange, it is as if the Hspda signal were unavailable, but it´s not...

Yes, I really wanted to have the H connetion all the time :):)

thanks for the help...

I'm running on "Unknown Baseband"...Should it be a problem??
[LG Optimus 2x] bujcri:
I was on "unknown baseband" for a week and did not have problems, except maybe wlan reconnect after deep sleep (TG P990 V30A). I'm still not sure if wlan is working now ok, but I flashed today v30A BB, so I can confirm that smartflash is working with new ICS partition layout, despite what it says on the first post of this thread.
[LG Optimus 2x] tonyp:
Updated ;)

SmartFlash not compatible with ICS layout removed, that was back in the old days before the new cwm.

Sometimes I just need a second reminder in the thread - I saw the first question about that, decided to update the OP later and forgot about it :angel:

Oh and the Unknown Baseband FAQ entry got expanded.
[LG Optimus 2x] spyrosk:
Thanks friend.

HeHe, I'll keep that in mind!!:) ( the second reminder I mean )
[LG Optimus 2x] bujcri:
Anyone found suitable LG drivers for Win 8? I couldn't flash BB with drivers from first post, OS would crash. It did not work even on virtual XP or Win 7 installed on WMWare. Each time Windows 8 crashed.
[LG Optimus 2x] Ferrum Master:
What? I've used Win8 since first previews... no problems with smartflash. For nvflash you have to disable driver signature during win boot. I've just flashed 30A bb using Win8.
[LG Optimus 2x] bujcri:
Thanks, it worked :) I installed APX driver disabling driver signature. Should work I guess also for the LG driver for SmartFlash, cannot check now.
[LG Optimus 2x] mas2112:
I have the same problem. Windows 8 would crash every time I plug I in my phone in upgrade mode (holding volume down while plugging in usb). I tried the latest lg driver, and the one version before.
[LG Optimus 2x] Ferrum Master:
Either you got ****ty PC. (YES, most probable reason why!! Your BIOS vendor hired LG's monkeys to write it :D, I've got so much pain and funny moments using AMD integrated USB etc the most stable ones seems VIA external PCI USB for me(2$ on jewbay), I dunno why, it shouldn't be like that(In ancient times I owned some VIA stuff, gosh, it was a nightmare), but it has proven to be so in 8 years repairing thousands of mobile phones (my repair count already is over 30K units so I might have some experience)

Use modified USB cable using around 910K resistor to USB ID pin... (I've tried from 830K to 940K phone enters smartflash).

Update your motherboard drivers!! Intel inf!! Then don't use USB3 (update those nasty Renesas drivers also, they are famous causing BSOD, DPC latency spikes etc... I disable the in bios anyway, no use of that USB3 either way)
[LG Optimus 2x] mas2112:
I have an hp envy laptop, which only had usb3 ports. Maybe the lg drivers don't work with usb3? To work around this problem, I just used my old laptop with Windows 7.
[LG Optimus 2x] Ferrum Master:
My condolences. Currently there is no phone that is normally and safe flashable with USB3. You've successfully bought an over hyped PR crap.

USB has broken compatibility with countless devices ranging from, mices, keyboards, audio devices (including professional) and custom devices as our phones. It simply isn't 100% backwards compatible with 2.0, as it breaks UART mode and has additional interrupts and handshakes etc. Even the chips are buggy and not laid out.

So don't ever flash any phone using USB3. Especially Samsung ones, I haven't tried connection with a USB2 hub and then using a forced legacy mode, even though I have an access to JTAG tools to recover boot, but I am not a masochist to try.
[LG Optimus 2x] Robin2:
True. My pc gives me a blue screen when I connect my phone in apx mode to usb3. (Windows 8)
[LG Optimus 2x] tonyp:
In my opinion this thread has became a huge success.

I started it as I became more and more annoyed by all these baseband-related questions. Those of you who are hanging out here for a while will remember - pretty much the same questions on every page of every thread.

I think the situation improved a lot after this thread has settled.

Recently with the introduction of CM10 new questions about RILs/BBs raised.

While I did update the OP here and there, I don't think the new CM10 & Stock ICS situation is addressed properly, yet.

Thus I'm planning to update this thread over the holidays.

I'd like to take that chance to update/improve the whole OP. I will go through the posts and see which sections could use some updates.

Please give some feedback about that, as I need your help to identify which parts need some overhauling.

Anything particular you'd like to get added? Any section that should get re-phrased or expanded? Any links missing to other threads or tools?

So please give feedback about every aspect of this thread. Positive and negative.

Every kind of suggestion is welcome, the more detailed the better.
[LG Optimus 2x] Patrick Morgan:
i think this post is pretty damn well done,

i wonder if a link to the AIO tool kit would hurt? it has the option to flash BB now, in regards to the layout and information. i believe in the saying.

if its not broken don't fix it. you have done a awesomely great service helping us here at XDA.
[LG Optimus 2x] LarsPT:
I also think you've done a great job and there's nothing that needs much overhauling, like you said.

When I decided to change my BB I just followed the OP and didn't have any trouble at all!

Thanks again tonyp.
[LG Optimus 2x] aaaadrian:
I would remove the poll, as it gives a distorted image (without 521 and ICS basebands) and it appears on top of every page.

I would add a link for V30A final (not leaked) in post 1 direct downloads - or change the link name - many people insist/think there are differencies between v30a leaked and the final official ROM/BB.

Also in post 2 there are at least 2 mentions of a 512BB. Is there such a version or is it 521?

I would consider a clearer distinction for which BB for which ROM type (GB, CM7, CM10, ICS)

These are suggestions for minor things, but could help a first time reader.

Otherwise very, very good thread.
[LG Optimus 2x] ronalith:
It's not a huge deal but the names on the baseband files are somehow different, it would be cool to have the same naming pattern for all of them. I assume they all came from different sources but once you have a few downloaded on a folder you get confused and have to come back to the thread to check which file are you actually looking for. It all has trimmed a bit with the few basebands that came with ICS but still, some people might find it helpful. Something like the old DEVICE-VERSION-DATE.fls but keeping it for all the files. Thanks. This thread rocks indeed.
[LG Optimus 2x] sibbor:
If baseband versions ever get updated I'll make sure to update GetRIL too.
[LG Optimus 2x] benhotw:

[LG Optimus 2x] salisbury_steak:
I'm sorry, I only used the leaked v30A in the OP, so... there's a final one?
[LG Optimus 2x] tonyp:
The v30a leak and the final v30a ROM are exactly the same (they got the same md5 hash), so no, there's not a difference at all.
[LG Optimus 2x] SuperSkill:
By trying again lol, try another port, another baseband before, I was always fighting against 20c Russia, always timeout, I usually made it after 10 attempts, I wish I'd knew the reason as some succeed every time and some don't....
[LG Optimus 2x] sturmtruppler:
I'm going to install ubuntu on my pc, is there a way to run smartflash on linux, maybe with wine?

Googled for it, but never found an answer...
[LG Optimus 2x] salisbury_steak:
Thanks buddy. Phew, I thought I need to flash again.

Btw, I've been really busy the past few weeks and I wasn't able to follow O2X development recently. But, thanks to your thread, I was easily able to get up to speed about the latest BB (& RIL too).

Thanks alot for all the work you're pouring here and all the other threads mate.

I actually got a timeout error at the end too (Was flashing the v30a BB). However, it was at the part where Smartflash was just trying to reboot my phone or something. So I simply disconnected, turned it on, and bam, v30a is recognized as the BB in my DMX 1.1 ROM. :)
