Dear Devs,
I was facing a problem related to Airplane Bug on Miui/CM7 roms, so i googled related to this but couldnot find anything of help. So thought of asking for your help..
1) Whenever i flash a stock or custom froyo/eclair/GB rom, it detects my network which is BSNL india without any problem
2) But when i flash any CM7 or ICS rom, my phone doesnot come out of Airplane mode at all..
3) So, i tried everything, but of no use.. IMEI is good ... nothing is corrupted
4) Yesterday, when i changed SIM card to other operators present in india, the airplane bug is gone
5) so i feel that problem is either with BSNL operator or may be with sim card as every other operators sim cards gets registered and there is no airplane bug there.. ( i tried Airtel/Docomo/Vodafone/Idea networks)
Is it do with RIL..
Kindly help me as this is same problem faced by so many people around globe with their operators..

Okay!!! So i'm not alone in this. I thought it was some other issue.
It's there with BSNL Network [ India ] . The radio doesn't turn on at all!. i flashed the JVT Modem as well ( Which works with samsung ROMs in the same network). The issue has been there since ICS Build 6/7 and MIUI also now. No networks showing. The radio is not turning on.
thank god!
I always thought it was my phone.
So it is an issue with BSNL.
please post a solution if there is any.
Thank you.
i had this problem with my phone a few times, i am living in turkey and i am with turkcell right now. i managed to solve it with a few steps:
1. turn on airplane mode from the settings page (not from the power menu). make sure you see the airplane logo in the status bar.
2. reboot to recovery and wipe cache only
3.when the phone boots up from recovery, turn off airplane mode from settings, and go to mobile networks page. select network operators. it will search for a while, go grab yourself a cup of coffee. after 5 minutes or so, wake up the phone and you will see the signal bars and phone is functional again!
u r not only who facing this problem ...
Hi .. i have same problem in BSNL .. while using CM/MIUI or CM based any rom ex: insanity rom .... even i m not able to solve airplane bug ... i searched a lot regarding this n read a lot .. there isnt any proper solution .. when i restart my phone sometimes No Service shows .. n that airplane mode still on ... i complained to Dev abt this ... and even about support for third party call recording software .. there is no solution yet .. ...
plz dev do something for issues ... we are huge fan of your rom ... and dont want to switch over any other rom ...
thanks ....
re-flashing same modem number of times do work some time..
pl you people and i also do trial and error to find best suited MIUI CM7 modem for India-BSNL
i was partially successful with jp5 here... Phone once detects network ... but on next boot... Network is gone again...
so...
flash different modems from recovery.. and if lucky enough.. can get network in 2nd or 3rd flash... ( you may also clear the cache)
please try different modems...
from this link... http://forum.xda-developers.com/showthread.php?t=1158783
lets post our findings here.. and find out best modem for INDIA
@all .... i m using MIUI ROM 1.11.25 has no problems from last month ... i got problem while i updated it .. then after there is no "No Service" problem ... try out guys ... it works like a charm .. i m using BSNL .. n dnt have problem ..
Are you subscribed to 3G services? It seems like the Samsung RIL implementation toggles to 2G mode quicker than Hacked RIL implementations that are on CM7 and MIUI which don't work so perfectly.
If you are not subscribed to 3G services, the phone would try to register on the 3G network upon Network Toggle or Airplane Toggle quite a while before actually switching to 2G. At this stage, you get the No Service bug which lasts quite long on CM7 or MIUI before getting back to 2G and getting a Network lock.
Have you tried using the 2G only mode and see if it gets better?
Unfortunately, RIL Implementations are properitary to Samsung and we won't be able to use them on AOSP based roms due to lack of source code.

Hi guys,
I already have some experience in changing ROM, and so on.
Recently, I gave up the experimental ROMs that have always worked well for back to cyanogem stable 7.2.
The first week was very good, but in one afternoon, for no apparent reason, my signal disappeared. The smartphone settings showed me that my number was +0000000000, the imei was shown correctly, but for some reason imei_sv was unknown. Put other roms, but the problem persisted. So I decided to go back to the stock ROM, I lost my root and CWM. Surprisingly, at first, I could make a call and receive another. But after the excitement, the same problem again.
Sometimes, the settings show my number correctly, others turn to show +000000000 ...
Nevertheless, the display shows me a good sign, and the phone recognizes messages in my mailbox.
* Detail: I can not in any way put CWM. I spent the whole day trying, and absolutely all the methods that the internet gives me do not work.
UPDATE: Finally now I have CWM, but the problems are present.
Rom: European stock v30a - Android 4.0.4
Baseband version: 1035.21_20121130
If someone can help me, would be very grateful!

I did not do this procedure. But I turned it into a brick, and formated all partitions and redid them with a fantastic tool here forum, All-In-One Toolkit -> http://forum.xda-developers.com/showthread.php? t = 2020737. This procedure can, by itself, restore a corrupted imei or delete data cal?
If not, how could I do this? And because it is corrupt without any procedure? I was at home and no apparent reason the phone lost signal. At 13:00 he had signal, and at 14:00 had no more.
I considered another possibility: virus in sim card.
This test will only be able to do tomorrow, using a sim card that is not "infected", if that would be the problem.
UPDATE: Today I bought a new sim card and tested it with the stock rom newly formatted. I had the same problem, but strangely, the first few minutes of use, everything works. After a few minutes of use, the signal sim no longer works, and after a few hours, the smartphone connects on a rece wifi, but the signal does not stabilize: connects but does not have internet access.
REALLY DO NOT IDEA HOW TO SOLVE THIS!
I really need help!

You really should try Erase CAL data. http://forum.xda-developers.com/showthread.php?t=2087215&highlight=wifi the first Post what you need. If you having problems with restoring your imei then use putty instead of hyperterminal
I did not do this procedure, but deleted all the partitions and redid them, and I believe it made the signal back. Thank you all for the help!
UPDATE: The problem is present again! I restored Imei, erased CAL data, change billions of basebands and no sucess. If I search for networks, it´s fix, but only any minuts, and the problem returns again. I have sucess for any days, but the sms were frequently lost, and after, my signal losts completly. It´s a possible hardware problem?
I really need professional help of my friends of XDA.
You are tried to erase cal data again by smartflash using 30B Rom and Baseband 30B?you o2x is from china or korea?

I have a problem with this phone. I got it locked to a network so i rooted it and changed bootloader to new bootloader and instaled kowalski kernel ((alpha) now I'm on M1 and the problems are still here)), after that I tried many different ROMs but I get the same problem all the time. First problem is that my phone finds a network and I can recieve calls and messages but no data connection and I can't save an APN (I fill in everything and when I click save it just brings me to APN settings without the APN iI tried to create. Second is the random reboots, it just happens when I do stuff (doesn't matter what). And the last is bootloop which happens and then I leave it just to turn it on later without problems.
Could you please help me and tell me what kernel, ROM, bootloader, baseband and everything to install to make it work. I don't care about the data that will get erased. I just want it to work (even on stock ROM and kernel which I can't find) THANK YOU IN ADVANCE GUYS

You can try and flash another ROM to see if it's the roms problem, or do another clean (by wiping system,dalvik-cache,cache and data ofcourse) install of your current ROM. :good:

It could be the problem of your Sim network provider. Have you tested it out with other sim providers and see if you can place calls!?
Well in my case it somewhat worked with
*#*#4636#*#*
and then i select the GSM (PRL) and of the radio signal
now its working fine
now i want to know by switching of that radio signal will there be any other problem?
Hello guys im new here and i tried lot of things to repair my wfi problem.
So its my mom phone and one day she called me about selfrestart phone in night and there was image of bootloader and startup failed.
So after classic factory reset and etc my wifi still not working. The problem is i cant connect to any wifi. I can scan it but wont connect just say disabled or saved but not connection.
After this i tried flash stockroom succesfully after 2 days of hard work So i flash stock room but the problem is still there so im not sure what can i do anymore. If i can try flash some newer rom or custom rom or its just hardware failure? has anyone have problem like this? All others things work normal like data connections etc. Sorry for my english
1. update so i flashed another lineage room just in case and still not working.
2. i notice in system information that wifi mac adress is 0d:00:00:00:00:00 so can be hardware failure probably.
3. Hotspot wifi is working so i can connect from another mobile to the broken wifi mobile
