Miui rom network breakdown!

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.

This is good news. Will try. Where'd you get 823?

I got it from temaseek's media folder

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.

LG OPTIMUS P990h "NO SERVICE"

Good morning my problem is this after flashing a new baseband (the 521) to install the ROM CyanogenMod 7.2 Custom ROM Cyan 3D lg optimus 2x presents me no service and an X in the signal bar, repeat the procedure, flash baseband and reinstall the ROM but the problem persists, the baseband originalmete 725v10d tennis, I have a LG Optimus 2X p990h (Movistar Venezuela)
THE OPERATOR APN are ok, RIL 218 IS COMING WITH ROM
I tried another SIM card from another phone and it does not work, another phone MISIM CARD IF IT WORKS, thanks in advance for the help.

Try a different BB again and also a different RIL. I have this problem sometimes when changing the RIL.

thanks for your reply I tried baseband 725, 313, 521, my team is rooteado, I installed cm7 kang, the team still does not work even with the 218 ril ROM brings the truth that this is not happening, the flashing the baseband successfully and still says I have no service, I'm thinking a hardware problem

Try to flash via nvflash and after that to play around with the RIL and Baseband. It may work

Though I'm not a LG optimus P990h user still I would like to share something about this problem. I'm a Samsung Galaxy S 2 user & just about a month ago I faced same problem. I do all possible things to make it normal(try different sim, hard reset, flash different rom) but no luck. After that I visited upto 3different service center n after a details checking all of them told me the same reason that my motherboard 2 chipset got damaged.
Now how you will know if this is a hardware problem.
Now goto settings > about phone > baseband version - Does it shown unknown.?
Press *#06# is ur 16 digit IMEI no is blank.?
If both answer is yes, then this is definitely a hardware problem.

[POLL] Official CM10 network and RIL discussion

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
After, i've full-wipe and install the last nighlty with gapps.
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...
EDIT: Forget it, already checked the baseband thread in development, gonna flash the matching BB now

Just use the 218 BB and stop worrying about ril.
Sent from my LG-P990 using xda app-developers app

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

Well, two very different opinions... which of them is right? Baseband flash ou 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
BB 0725 V20Q

[Q] On bootloaders and BB

Is there a relationship between bootloaders and basebands? I mean, can I use an old BB (say a v20a or v20g) BB with the new bootloader? Anyone tried it? I'm asking because I've flashed a stock ICS (aka v30a BB, new bootloader) and then moved on to ParanoidAndroid by TonyP. But now I wish to test how my 3G behaves on my original BB, but I don't want to re-install everything. If I can keep the new bootloader, a simple nandroid backup will do for the inevitable wipe caused by the BB flashing.

Install GetRil on your phone (you can find it on Play Store),it'd say you if you BB and you ril are compatible or not.

I'm asking about bootloaders, not RILs. Since I'll keep on using PA, I'll use whatever RIL comes with the ROM. As Tonyp explains in the Basebands thread, you don't mess with RILs in CM10 based ROMs (which PA is one of).

You can use v10 v20 bb with no problems at all. I think the best option for cm10 roms is to use old bbs since with v30 bbs cm10 roms show one hour less than it should be. I meab the time is now 8:30 but on a cm10 rom it would show 7:30

Well, I've never had those time problems. Maybe it's because I don't get time from my network (I try but it seems that they don't send it anyway ).
Since I need some time to do the backup, I'll try flashing the baseband on the weekend and when I have the results I'll post it here.

Newbie needing Baseband help...

Hi all,
I have just flashed CM7.2.0 which I downloaded from the official CM website....the flashing everything went fine but it seems unstable signal wise, high battery useage and also trying to turn on and off Airplane mode it sometimes wont work without a reset of the device. I was thinking possibly a Baseband issue?
The only thing I have no idea what baseband I am meant to be running on Gingerbread CM7....I was on the stock LG ICS rom before flashing. It says my baseband is currently 1035.21_20121130
Can anyone recomend the correct baseband for me?
Is the one above left from when I was running ICS?
Am I correct in thinking when flashing the baseband stays as it is....it doesnt come with the new rom?
I am sorry for all the questions but need big help.
Thanks
Tom

Flashing a custom ROM cannot change your BB. Your BB presently is the ICS BB and ICS BB are always not supportive of the GB systems and communication.Your battery drain signal, drops, maybe because of that too
So, you need to change your BB to a GB BB as the CM7.2 is gingerbread stuff.
Changing the BB is only possible with smart flash or KDZ method. Please check tonyp's Baseband thread in the development section for all the answers for BB.
Hope this helps
