Hey guys, I live in a rural area in the USA and I use to get a pretty steady 1-2 bars my house. Recently I started flashing my ROM with some of the ROMs here and I've noticed I can now only get maybe 1 bar by my window. I was wondering if somehow my radio got changed or something else? I'm on T-mobile. Thanks for you help.

What radio version have you got installed?
(in case you don't know, look under 'start>system>settings>device information>software information'.)
Here's a thread with lots of different radio versions for download: http://forum.xda-developers.com/showthread.php?t=549939
Different radio versions are often better suited to different geographic areas/carriers. Take a read and see whether there are any comments about a particular radio version from someone who lives near you/uses the same carrier.
It says:
4.49.25.17
I'm knew here and I understand the concept of ROMs but what is the radio for and does flashing the ROM change it?

You can go here...http://forum.xda-developers.com/showthread.php?t=549939 and read about the different radios. Some roms work better with certain radios. Flash some and see what works best for you..
The radio (not to be confused with the internal FM-radio) is the firmware which controls the device's various antennas (among other hardware). It sits between your device's hardware and Windows Mobile. The radio is a huge factor in your reception in a given area, so changing radio versions may help you. The only problem with radios is that your situation is completely unique, and therefore, nobody can tell you which radio is best for your location. My advice is to simply try the latest ones, and see how those work, and using older and older ones until you find one that works for you. The procedure for flashing ROMs and radios is the same. Just ensure you don't flash a CDMA radio, or you'll brick your device. Visit cr1960's link for all GSM Rhodium radios.

Aluminum foil wrapped around a fork and tied to my phone seems to work for me.
Flashing a cooked ROM won't affect your radio version. But if you flash an official ROM, that usually comes with its own radio version too.
Hi all,
Within the past week or so, I've noticed a fairly large drop in the signal strength from both my wireless lan and 3g signals. With the cell signal, it was even dropping to edge sometimes when I was outside in an area which used to give me full bars. Wireless isn't much better, and it seems to be fluctuating between 4/5 signal and 2/5 signal even though I'm close to my router. Again, I used to have full signal in the same location. Nothing really would have changed.
Yesterday I tried flashing Continuum (2.3.4) instead of running the stock 2.2 that I had before. The 3g signal seems to be *slightly* more consistent, although I'm still not at full bars, whereas I always was before.
Is this a common occurrence? Is it my hardware, and can I fix it myself, or do I need to send it in to Rogers? I've only had the phone for about 6 months now. I wonder if it's under warranty still (assuming I flash back the original ROM and bootloader).
If anyone has any suggestions it would be much appreciated. It's odd, but the wifi signal almost gets boosted when I'm trying to use the internet, but not to full bars even when I'm near the router.
Bump. Is this the wrong place to ask this question?
Cheers
My AT&T Captivate has similar issues. Mine started about a month ago. I haven't put any effort into figuring out the root cause.
Yeah, I'd really like to figure out what's up though. Does the hardware just crap out after a few months of use? Thanks samsung!

This trend happened with my HTC Aria as well. I don't believe its anything related to Samsung hardware crapping out.
So, if it's software, what would be consistent across a ROM and kernel flash?
I recently fixed a network error effecting call quality by flashing a new modem. I know our issues are different, but since you did flash new ROM i dont think it could hurt.

Stumbled across this article on Toms Hardware today and felt like it was a good read for this thread.

Unfortunately it's not just my wifi that has issues, but 3g as well.

Have you tried flashing a different modem? The one that came with your current rom may be different than you had before which would account for your weaker signals. Different modems work better in different areas. Try something else and see if it doesn't help, such as JK4 or JL3.
I haven't yet, but I actually had the problem before I flashed the ROM.
Where are you located. I have absolutely ATROCIOUS reception in Atlanta, and ATT says they have some 50 towers down. Your area might be the same. In my basement where I used to have 3 bars consistently, i know have to run around the basement struggling to get one bar to send a text. ATT needs to get their act together or everyone might start switching to Verizon.
In Toronto, Canada. We usually have good reception. It's only recently that I have had issues.
check with other people such as your family and see if they have bad service too, if so call your service provider, there may be an issue on their end. Other than that all I can suggest would be a full reset to factory and a master clear and then restart from there. While that is annoying, it might be worth it to solve the problem.
Hi guys (and girls),
I'm going slightly mad trying to figure out a stable setup for my O2X. I have been switching between the latest CM7 nightlies, and MoDaCo FR19. In general, CM7 gives me quite frequent black screens, and FR19 seems quite stable. However, there is one issue that is present in both ROMs.
I am unable to get a stable mobile data connection when I switch from WiFi. Sometimes it works, and sometimes it doesn't. To get it to work again, it sometimes works to switch to 2G only (and possibly back again). I have tried several different radios recently: 218, 606, and 622, all with the appropriate RIL. The mobile data connection for 218 drops in and out at random without any clear pattern. For the other two radios switching on or off 2G only seems to achieve stable connection. However, it does not actually seem to affect whether I get a 3G or 2G signal. The display can say H or G, even when 2G only is checked. Bluetooth did not work correctly with 606.
To top everything off, the GPS does not seem to behave consistently for a all the different radio versions.
I guess that people have different experience with different radios, so which radio are the guys in Norway using? Do I really have to slog through every released radio and spend the day checking each one of them? Can I expect to find a radio/from combination that blacks to give me a stable GPS and mobile data connectivity, as well as good WiFi?
I know this has been discussed numerous times before, but people never seem to reach any conclusions. I'm just looking for advice on how to proceed to fix my problem.
I'm on cm7 .77 and i honestly havent had a blackscreen since i flashed it (yesterday morning) + battery is good now. For me this is the most stable nightly so ill stick with it for 2 weeks on my holiday )
Edit: bb .502 ril 218(i think) dont have any problems with network switching btw

You probably have to, yes. This sounds more like a problem with the specific coverage in your area and how the phone interacts with the cell-towers than an actual problem with the phone. You may be in an area with weak signals from several stations, you may be in an area suffering from sudden bursts of noise, there could be a lot of reasons for why this is happening.
First thing I'd try is to upgrade to the latest official firmware (10C - 0622 for Norway), just to have a baseline for comparison. In theory this firwmare (and baseband) has recently been validated by the norwegian carriers, and should have the best chance of success.
Then you should probably do a manual scan (in phone settings) for networks, and pick one manually.
Also try using the INFO menu (*#*#4636#*#*) and see if choosing a specific protocol helps.
If you're still unable to maintain a stable connection, I'd say that'd be grounds for returning the phone for a replacement.
Weak advice, I know, sometimes there just aren't any quick solutions.

Sort of. In this thread http://forum.xda-developers.com/showthread.php?t=1035041 you'll find complete ROMs of the previous versions. Install one of those with SmartFlash, then run the LG Mobile Update tool to get the latest.
::Trym
Okay, I see, downloading now. So it is good enough to use one of the smartflash files, I don't have to use nvflash?

No, you don't have to use NVFlash. The advantage of using the smartflash method is that you get a completely "factory fresh" phone, with all the stock content present (movies, music, pre-installed apps) and you're sure to get a matching baseband and ROM.
Note that you have to flash both files, both the baseband and the ROM. The LG update tool won't update if you have a "new" baseband on an old ROM.
::Trym
So the firmwares from that post do not include the baseband? Anyway, I'm currently running baseband 405, so I guess this is sufficient to get the new update. And the new update will then overwrite everything to the latest official version, both ROM and baseband, correct?

Yes, it does. Each firmware pack comes with TWO files, the baseband and the ROM. To make sure you avoid any trouble, just flash them both, though, as you say, you can probably stay on the one you have, as yes, the LG Mobile Update tool will overwrite both the baseband and the ROM with the new versions.

Flashing of old firmware, with subsequent upgrade to latest release for Norway is complete.
I got version V10c, with baseband 1035.21_20110622, kernel 2.6.32.9. My mobile data seems to be enabled as soon as I get mobile coverage (which admittedly is poor right where I live). Even though it pains me, I guess I should leave it as stock for a day or so to see how it behaves.
I guess rooting it shouldn't affect performance in any way?
My initial experience is that it is much more snappy than the stock firmware that the phone came with, but time will show

Yeah, you probably should, as your mission right now is to find out whether you can get a stable mobile data connection or not.

Not to my knowledge, but I'd still advise you to wait a few days while sorting out the connection issue. Not that I think rooting it would affect that one way or another, but if you can't get it work as it is, you can return the phone in the state it is now, factory fresh.

It certainly is. It also *stays* snappy over time, which can't be said for the 10a/b versions.

The first test drive with the new firmware has been completed. On the way out it switched to mobile data flawlessly, but a longer drive it started falling out and reappearing for only short periods. When we stopped at the destination seemed to stabilise with a 3G connection again.
For the return trip I selected use only 2G network. The network connection remained stable for the entire journey.
I will have to test more, but the conclusion seems to be that it has trouble switching between the 2G and 3G networks when moving. I will try the same trip with a Telenor SIM card, and with different combinations of enabling 2G and 3G modes.
By the way, what is the difference between forcing 2G in the regular settings menu and in the special information menu?

The 2G only setting in the phone menu equals the "GSM only" setting in the INFO-menu. I'm far from an expert in these matters, this thread has an overview: http://forum.xda-developers.com/showthread.php?t=675136& of what the different modes do.
::Trym
More testing seems to indicate that as long as i leave "use 2G only" check, my mobile data connection seems to be pretty stable. It even switches between 2G and 3G, although apparently a bit more conservatively.
I guess I get to keep my phone anyway
Now for some rooting...
Just an update on the results from my testing. The second time I went out my mobile connection never appeared. This was with only 2G checked in the settings menu. In the Info menu, this corresponded to GSM only.
I then changed it to GSM auto (PRL), and then I got my intermittent mobile data again. I then change it to WCDMA preferred, and my data connection seems to be stable for now. This apparently requires much more testing...
F another chapter in the connectivity saga. Having WCDMA preferred selected in the Info menu, things mostly work, although the data connection drops sometimes.
Another problem I'm noticing with the stock ROM is that it usually is unable to reconnect to my home WiFi network when it comes within range. I have the money was selected to reconnect. Sometimes I even find it disabled in the list.
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.
I am currently using viper 7.0.1 and i get pretty consistent signal everywhere i go. I've been toying with some of the aosp roms and it seems like i loose signal more often is it the difference in the roms?

There is a well known fact that OEM base roms do not show the proper signal strength. It was even found that they removed the one bar image and just used one with 2 bars so you thought you had more signal then you did.
AOSP based roms show the true signal level.
