KA: Dev. CM7 / MIUI Airplane bug ...

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.

no signal on 4.4.2 KitKat. what to do?

There is absolute no signal... On original ROM it says "turn off airplane mode" when I dial some number, but it's not in airplane mode.. Tried custom ROM, but there is no signs at all.
Before that I downgraded phone to 4.2.2 ( A1 and 10b version) and I got signal, but phone was not usable. It was crashing, it was freezing and so...
So any suggestions? Maybe there is some radio problem or what?
Thanks

Have you tried a new SIM from Verizon? If so and you're still under warranty, revert to stock and send that bad boy in for a replacement!
Sent from my VS980 4G using XDA Premium 4 mobile app

i'm not on verizon . i use it on different carrier (outside of usa) , but it was same on verizon . and it's not sim problem , because by downgrading phone to 4.2.2. it works , i can make calls,ect , but it was freezing and unstable . but when i update it to 4.4.2 there is no signal att all , the radio is disabled ..

I'm getting this error "to make a call turn off airplane mode" when i try to call
but it's not in airplane mode..
i read that not only me or not only verizon phones has this problem , it seems the problem is in kitkat , because i saw this problem on other devices too , samsung note 3, htc one or ect...
so , is there any solution about this?
once again , i've downgraded phone and it got signal , but soft was freezing , i think it's kernel problem or something like that . seems like it's not possibly to downgrade 100% to stock

i've flashed this
https://www.google.com/url?q=https:...sntz=1&usg=AFQjCNHKZ4NT8iAxIZJyc9bW7jjJv7sQkw
and now everything works
thanks to developer !!!
still same problem appeared . WTH?!
fixing permission in recovery and several restart (2-3 times at least) fixes problem , but it's not permanent fix , working until next restart (i think)

Hi everybody (and sorry in advance for my poor english) !
I am having exactly the same problem as the OP. To explain the situation in a nutshell:
I have the SM-G800F, for about a month. It worked fine, until I moved to the other end of France (it probably has nothing to do, though). Passing on the highway, "Emergency calls only" showed up while I was looking at my emails. The problem is that things never got back to normal.
The situation :
As I said, the same as the OP. When I turn on my phone or I go out of airplane mode, my phone tries to connect to 2G, then 4G / H+. The process takes a few seconds, then any indicator (left of network "bars") disappears, and I can't issue or receive calls, nor use data.
But if I force "2G only", everything works just fine.
I was using a rooted 5.1.1.. In the meantime, I tried several suggestions found here or elsewhere:
-Turn off the phone and on again : Nothing
-Enable / Disable flight mode: Nothing
-Remove / Replace the SIM card: Nothing
-Putting the sim in another phone: everything works just fine, so the problem may not be a faulty sim card
-Wipe Data / Cache Data then use Odin to reinstall a stock 5.1.1 rom (I'm really a noob to find the right words, sorry in advance, but my phone says, under the "version number" field , LMY47X .G800FXXU1BPC4 and the ROM I used is named : -G800FXXU1AOG2_G800FOXX1AOG1_G800FXXU1AOG2_HOME.tar.md5 filename
Manual carrier selection : Nothing
-Turn on Data Roaming : Nothing
-Checker my APN : Everything seems just fine
I can't tell for sure but I do not think it is related to my home. My problem began on the road and took the rest of the trip (2h/3h), and even around in the city, it remains. Moreover, my backup phone and the other people on the same network as me (Orange) don't encounter this problem.
So, I'm a little bit confused and a bit worried because of Knox (0x1: /). If you have opinions, advice, guidance, thank you very much in advance!

No, I really don't know what the problem is I think it's something in the phone itself

I've got the same problem too
Did you find the cause of this issue in the end?

Hi !
Not yet ... I have another phone now but i still try now and then to fix my S5 mini.
So far, nothing worked. Some tech guy told me it was a common issue with that phone's antenna. Also read that from several forums.
Still, i read that some users were able to fix similar looking issues by flashing the modem file with Odin. I'm a bit n00b but i guess i'll give it a try.
Any success on your side ?

You can try searching for your carrier manually and choosing it.

Thanks, but i already tried that many many times. My S5 Mini just displays "Network XXX unavailable" (or its nearest equivalent in French)
Did any of you manage to fix that by flashing your modem file with Odin ?
I've tried additional stuff but nothing seems to work. Back to stock Marshmallow. Still loosing radio signal whenever I enable 3/4G.
Maybe the bottomline is "hardware failure" but who knows...
Thx everyone!

Have you tried a deep reset? If it does not works, try a custom ROM...

Hi !
Thanks for your reply,
I did try "Factory Reset" and "Wipe Cache" while in the Recovery Menu (Home+Power+Vol Up if I remember well). Is that what you were refering to ?
But I think I didn't try flashing a custom rom. Could you recommend one ?

Yes I was meaning this. For a custom ROM i can recommend One of the latest with NOUGAT like Lineage OS 14.1

Hi,
I installed Lineage OS 14.1, it's great but the same problem keeps happening. Everything works just fine in 2G, but whenever I enable 3G or 4G, my phone looses radio siglal and switches to "Emergency calls only" after a few seconds.
Any other thoughts ?
Thx !

As a side question, would you think of any way to rule out/confirm the possibility of HW failure ?
Thanks again !

Did anyone found solution for this?

Hi,
I've got the same problem. Tried to flash with Lineage 13.0, then 14.1 and still the same problem.
Anyone help?

Flash the last modem/baseband, did yoy try *#*#4636#*#* ? You can manually select wcdma only(3g) or lte only(4g) (sorry for my bad english)

still not working

When I choose 3G/2G auto connect from 1 line ti go to 4 signal.. so no LTE /4G for now..

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?

A few questions...
1. What model/carrier?
2. Oreo or Pie?
3. Are you rooted?
4. If so what mods have you tried to use?

Hmmm...well this is normally where I would suggest flashing a KDZ but that I'm aware of that's still not possible....but what you could try is switching from Slot A to B or from B to A depending on which you currently have active....its possible that your modem for corrupted for some reason....and it may be fully functional on the other slot....but it's just a guess

Same result...I took the sim card out completely, still having wifi issues now

I'm having the same issues. Mine is from T-Mobile and it all started when I upgraded to Android Pie.
