I'm oppening this topic because i see that some users has network issues on the gingerbread releases. That's happens since first v20 build.
I had tried all the possible basebands and ril's, but the result is always the same: instable connection.
- Connection die suddenly and just returns after reboot
- Sometimes the signal of network drop and returns again
- At TIM operator cant get the "H" icon on topbar just 3G, with i can VIVO can get it H normally (it's not a feature, believe in me)
I guess that's something related to baseband because for some users everything goes normal.
Tested basebands:
725 for Gingerbread with matching ril
622 for Gingerbread with matching ril
725 for Froyo with matching ril
0622 for Froyo with matching ril
Hope someone can help, i really love the new Gr4 release, but i can't abdicate data connection for sure.
PING TIMEOUT STATISTICS http://dpaste.com/637671/
Problem solved:
1) Disable 'Automatic date/hour settings' on Settings > Date/Hour > Uncheck Automatic
2) Disable or change NTP parameter. In my case, i downloaded the ClockSync app (available at market) and set mannualy the NTP server of my country (in case br.pool.ntp.org)
I really don't know what the relation but until now, i get a stable network connection.
Hm, I tested 823 BB with matching RIL and I have to say that everything is fine
By the way: I have TopoGigis GB Release v1.8 SP1 (didn't want to upgrade since everything's working...^^)

It's good for you. Im seeing thats not a general issue, happens just with some mobile operators.
Unfortunally here i cant get a stable signal, im pretty sad about that.
I have no problem here too with bands, running 622..
if I were you, I'd stick with the baseband that came with your phone, it was intended by your carrier..

I already try that, same results.
Have you tried set dns pro? i dont know if it'd make any difference for you, for me it does.
When opening the app for the first time, it shows the phone is using google dns (8.8.8.8). i changed it with open dns, it went better. Still a bit slow (the ping, maybe), but better.

Already tried that, no sucess.
The slow speed doesnt bother me, the bad thing is the network drop.
I got those signal drop on 725 /614 /622 / 823 Baseband...
Best was 622 but with horrible voice on call !
Since CM 146 the 725BB don't work (many signal drop) so i try Miui with same result...
PS : i use getril to match RIL but sometime the BB is unknown and only restoring backup works..
Sorry for asking, I not so familiar with your problem.
Have you installed any apps in your phone, or the problem exists with untouched= after the rom installation?
622 for Gingerbread with matching ril ? please post link

What is exactly your configuration?
622 baseband for gingerbread or for froyo? The same question for RIL.
Thank you.
@felipemadox
Did you try BB 622 (gb) + standard cm7 RIL 218 + Network set to 'gsm auto prl' (after very reboot!) + No time syncing via android settings (use external app for this)??
This seems to be pretty damn stable! At least for me.

I guess that i cant use RIL 218 because im on Modaco Gr4 2.3.4. I already try the gsm auto prl and no luck with stability.
What means the "time syncing via android", i did not understand. Explain, please.

Disabile ntp server sync and automatic time sync from network.
ntp server sync and clock sync is already disable...
i don't have pin code asked any more so no network...and baseband is unknown !
Also tried with Gr4 based ROM but signal drop is still there...
PS @ Felipemadox : Those options are in the clock options

Hi I cannot enable my bluetooth.
When turnning it on in the configuration menue
it turns from changable to greyed out and cannot be used.
I have installed the stable release of CyanogenMod7 7.1.0.
I run baseband 1035.21_20110725 Kernel: 2.6.32.45-cyanogenmod [email protected] #1
Get RIL shows: RIL 0725 /V10d, Europe Open)
Any idea what might be wrong on my Phone.
With the original ROM bluetooth works, so it cannot be a hardware issue on the phone. I have reinstalled the phone several times but no success to get bluetoth to work.

Hello there, I had the same problem yesterday. I have tried a couple of bluetooth switches and directly from the settings, but none of them worked. I think this is a bug. I had to return to stock to get bluetooth working again. weird.

Bluetooth File Transfer 4.72
this app will solve your issue
For 725 you have to flash all 4 .fls files otherwise you'll get issues like wifi not turning on.
I'm currently using MIUI ROM 2.3.7 (build MIUI-1.12.2)
baseband: 1035.21_20110405
kernel: 2.6.32.45-cyanogenmod ([email protected]#1)
Curently having network breakdown issue. might have a few breakdowns in a day, sometimes don't have. do i need to upgrade baseband or kernel? can anyone help me please. i'm having a lots of appointment daily as i can't have breakdowns so often.
I don't understand what you mean by breakdown? Is it complete loss of signal? If it is then this happened to me in the galnet's latest weekly and ICS build. I don't know about the ones from miuiandroid or miui.us, as I haven't tried them. But if they share a similar base, then theoretically they should share similar problems unless some post-release fixes were added like those of galnet.
To recover, these worked for me most times:
reboot
manualy trigger network registration
I'm back to CM now. It's most stable and usable for me.
ya, totally loss of signal. its bored to keep rebooting all the time. i dont feel like using the basic android layout/UI rom. MIUI is nice but got some issue. sigh.... anyway, thanks for replying. anyone else would like to help me out???
Well I used 218 bb before, jumped over to 823 and matching ril. No more breakdowns.

You can get it from Temasek's mediafire link. Huge thanks to him..!
But flashing this is little tricky. You need to extract the file, then flash the .fls files begining from the biggest file to the smallest - in this order.
flash R375_SIC.fls
reboot the phone
flash AENEAS_FW.fls
reboot the phone
slb.fls
reboot the phone
psi.fls
reboot the phone.
I use smartflash to flash basebands, that is available in the same link.
Hope this helps.

Lol...great minds and that...!
Thanx Divyan Im at work so its great you give a proper reply
really thanks to u.
No Problem, guys.. Glad that I could be of some help - so little comparing to what we get from XDA.
In the meanwhile, I did test MiUi 1.12.2. too. I used to get this problem of MiUi goes to airplane mode at times.
Then I have flashed Owain's Tweaks. I did make a difference. Phone did not got into airplane mode anymore. Above this I have flashed ironkernel too ( seeking better stability - with undervolt settings of -25 v using pimpcpu).
This combination worked good for me for a couple of days without any issues. Then I jumped back to CM7 Kangs .
You might give this combination, if you feel like.
I'm using 1.11.4 and been having a few issues recently with loss of signal and a reboot was the only thing that fixed the problem. I found that I had a mismatch of baseband and RIL. S I used getril from the market and everything seems ok now. Only had it on for a day so far but it's been fine...
Helllo. I have it the same problems with the network. My phone was losing signal on all roms, cm7, miui, modaco, until i flash the baseband 07 25 and everything works well. Tomorow i will try the miui rom to see what happens.
divyan, i crash my set now. miui did not work on my 2x. tried flashed cm7 and kang. installed but did not boot up after 10 mins each. i downloaded LG RIL and GetRIL.
LG RIL did not mention if my RIL match with the baseband or not. but GetRIL says my baseband does not match with my RIL. i did follow your steps to flash the 823. not working thou.
now in CWM i can backup but i kenot restore. its automatically unmount the /system. darn. i think something wrong with my 2x.
seriously can u teach me how to redo all the stuffs?
i really like miui!

i have the same problem, with EVERY rom.
currently on 0725 baseband, V20L october version, nothing different: i got signal loss once-twice a day.
tried BB 0208, 0315, 0405, 0602 as well.
I 'll have to try 0823 with 4 separate files, as suggested in this thread
My phone always goes into airplane mode (by itself) after a reboot and a few hours of sleep time - im on cm7 with 725. Once that's done I just set the airplane mode off and it stops disconnecting from the network...
currently running on cm7 night #204 with 0823 and 0208 RIL. been good so far but got issue once i flash ironkernel. dunno why.
Initially made this for my hybrid ROM v20M/v20E but don't use it any longer as I replaced whole v20E framework with v20M framework.
But for topogigi / v20E users this could be helpful.
Combined with an actual 0725 Baseband of v20L or v20M and a RIL like the italian v20L 0725 RIL this framework file will fix the flooding with fd_not_activated messages (in 3G mode!!) in logcat for topogigi users. It will be just like on v20L/v20M ROMs.
Recplace your current framework.jar in /system/framework
And backup first!
Anyone tried this? Will it work for Gr5 (20L)?

Omg, why would one want to put a v20E framework file over v20L where the FD_not_activated logging is already fixed (I'm talking about 3G not 2G)??? Also it would cause bootloops... Think people, please think...
Opps... sorry! I though this is a 20m version that can be used on topogigi.. and last I check I still have FD not activated, but yeah, maybe that was in 2G becoz I use toggle 2G to manage my 2g/3g connectivity. Apologies again.

No problem, this is a v20E file, you can use it on topogigi or other v20E ROMs and it will fix the logging flood of "FD_not_activated" in 3G mode!
So you can use this file if you use topogigi!
In 2G you will still receive the Log, as in all other ROMs (v20L/M)..
I have a 0622 baseband and my phone is from Korea, but i live in Brazil, and i'd like to know if i need to change the baseband because im having some issues with my phone network, like sometimes the phone loses the signal and then it nevers come back and when i go to settings/wireless&networks/mobile/set network
it still lists the operators signal.
And if wanted a factory reset for my phone, how should i do it? Is there anyway to check the original baseband of my phone?
I'm using CM 7.2 with the latest etana kernel.
You can simply install the lastest brazilian LG's FW with its baseband using Smartflash or KDZ You can download all you need in the development section

there are a few things to check before you do anything/flashing:
1) try to check a suitable RIL...use GetRIL app or LG RIL Version app from the play store
2)I remember seeing something about the auto time selection in Temasek's Kang thread...try disabling the automatic time sync.maybe that is a solution.
3)tr changing to Temasek's Kang which is surely one among the best ROMs for O2X. HE ROCKS with his tweaks and cherry picks.
4)try using SU-660 Basebands....some of the devices dont respond well with normal BB.check tonyp's thread for a suitable BB and RIL combo.
going through a NVflash or kdz methods might be reserved for the last.
This is my opinion. but, take ur decision mate
Hope this helps

There is no BB/RIL combination at the moment that works with build version #5. All BBs show the same pincode error. Use build #4, that's working really well. Or have a look at a different ROM like Owain's.

It seems to me that the most common problem people are reporting with CM10 is related to the network, caused by the new RIL in the ROM. For those of us who actually use our phones as phones, this is not good! Also, any attempts to change the RIL via the GetRIL app, regardless of network or region, seem to cause a complete network loss.
So I thought I'd start a thread to consolidate everyone's accounts of their network experience with the new CM10 nightlies. Please post your region, carrier, and baseband, as well as a brief summary of any problems you have (if any). Getting all this info together in one clean list would be very helpful in assisting RC when he debugs.
I'll start here.
Region: Ontario, Canada
Carrier: Fido (subsidiary of Rogers Wireless)
Baseband: V21b (stock Fido baseband, never changed)
Problems: Signal bars fluctuate rapidly compared to CM7, on 3G. EDGE is less of a problem. Call quality is not affected so far. Able to make and receive calls and SMS.
Edit: Unsure if this is baseband/RIL related, but when I am calling through my in-car bluetooth handsfree, the bluetooth tends to disconnect itself and cut off my call.
Edit: List of basebands can be found on Tonyp's thread: http://forum.xda-developers.com/showthread.php?t=1658047
The same thread shows instructions on how to flash new basebands, along with download links.
I have also added a poll. Users can select multiple options if they find more than one baseband works.
Edit: OMFG, I forgot to add the V30 SU660 option in the poll and I can't figure out how to edit the poll... can a mod help me out?
From TrymHansen : http://forum.xda-developers.com/showpost.php?p=33504944&postcount=408
I've installed the BB From TonyP Thread >http://forum.xda-developers.com/showthread.php?t=1658047 Named 0420-V20m_SU660-Baseband

Now, Date Hours is OK, battery look good.
ps: I don't know how to do a "strike" ------ but battery drain with that
What's the matching BB to the RIL that comes with CM10? I'd rather go that way than changing the RIL...

I flashed many roms (stock Froyo/GB, CM, MIUI) using every time the updated baseband for Italy and I always forgot about ril and everything was fine; only once, following all the technical suggestions, I used getril to match bb/ril and had bootloop.
Now I have 20S bb and flashed CM10 nightly: wifi, phone voice/data and gps work fine.
EDIT: suggestion, download the bb of your country and forget ril

I had 725 BB in the beginning... which was ok... then I flashed the most recent BB (non SU660) and I was very happy with it, better battery, better reception stability... so for me, the more recent the better, that's why I'll start by trying flashing the most recent BB instead of going back in RIL.
EDIT: Even if it's the toughest way to start!
I previously had the stock V20S (flashed the KDZ). With V20S BB, no problems with JB. No call issues, SMS issues, nothing. Stable signal. Local operator: Claro.
I have a very strange bug...I knew when I was in the unofficial builds that I had 0725 V10d BB, now the system shows that o have LGP990AT-00-V20Q-262-XX-JAN-24-2012+0...is it a bug or something? I recall that ROMs don't change basebands...Is anyone else having this bug?(I have wiped everything and I had also installed the new nightly and nothing changed)

Your system says that you have 20Q bb and the system doesn't lie.
BTW, do you have some connection problems with CM10 or is it just a cultural problem?

I also have the same BB from V20s. Here are the issues that I saw in CM10, without changing RIL:
1. My phone number is shown as Unknown (in "About Phone").
2. Unable to see any contacts on my SIM card.
3. Unable to read a carrier's voicemail setup from my SIM card (need to configure access number manually).
4. Auto time is way off (need to set the time manually).
No problems with the actual functionality (signal strength, call audio quality, SMS, USSD codes). My location is Canada, Pacific time zone.

Flashing CM10 from CWM definitely didn't change your BB. Something else must have been done on your phone...

It has to be the RIL. Basebands are not affected by flashing the ROM, except for maybe the stock ROM. But custom ROMs like CM don't do anything to the baseband at all.
E.g. I've flashed CM7.1, CM7.2, and CM10 on my phone and the baseband has remained exactly the same as it was on stock froyo.
Region: Kerala, India
Carrier: BSNL
Baseband: v20i
Problems: unable to hear calls. everything else is fine it think
I can confirm that all issues with 0521 BB (no audio in call, bad time, etc) are solved with 0420 BB and default CM10 RIL.
Carrier: Orange
Region: Spain
Baseband: 0521 (v20s)
Problems: No audio in calls, bad time zone, random data drops...
Everything solved changing BB to 0420 SU660.
After install CM10 i lost the signal and battery status, please help me
