[Q] Constant FC over com.android.phone after CM6 or MIUI

Hello,
I need some help with my Milestone ( Cellcom Israel ).
After installing any custom ROM on milestone: CM6 (before the 6.1 & 6.1), MIUI or the FroyoMod whenever the phone stats it will:
FC every 2-5 seconds over com.android.phone (each time changing the signal to an bar + X on top of it ) and have no Signal (no network found).
I cannot go into mobile networks options (as each FC closes it automatically).
G.O.T 2.2.1 is running perfectly fine with no changes after install (installed the Italy Wind Rom).
Tried to change the Band from the OR to both the italy one + cellcom's (ISRAEL, which is my provided) but nothing helped.
I did manage to get it to work once (after removing the SIM, choosing Italy band, restarting and... i think thats it) but after another restart it got broken again.
I found a topic on this, stating that it might be a SIM problem and that replacing it will fix it, but its not much of an option (as there is nothing wrong with it to the provided).
Does anyone has a clue?
Thank you for your help,
Alon

My device has problems just like your MS, I asked this issue throughout the topic, but still do not have the correct answers.
someone said that the error was due to sim, change the sim will solve the problem but I think something was at fault in the development process. eg FroyoModv1. EclairMod, Ho! No! Froyomod, there are not errors. But MIUI, CM6.0, Sense .. phone.apk crash again.
hope someone will find out this error and help us.

try to do a full whipe clear everything and go back to your stock ROM, flash your version/region SBF with RSDlite from http://and-developers.com/sbf
and replace Simcard as stated

Well, i will try replacing the SIM, but im not sure that the provider will just approve of that.
I mean come'on, i can't tell them it doesnt work on CM6
as for the whole wipe, ammm, maybe ill try it later on today, in order to install CM6, i must install the GOT2.2.1 first ?

haha, just tell your provider that your sim has been lost and get another one.
I will do it in spare time .

Well this is weird.
Reinstalled MIUI, same problem
turned on and off airplane mode 10 times (while trying to fix), moved to 2g and other **** in the mobile network options, NADA.
Restarted, reinstalled ITALY BAND.
restart, everything ok.
had my fun with MIUI.
restart, bad again.
repeating the process of installing the italy band doesn't help anymore.
im puzzeled @[email protected]

if you want totry, I'll tell you my experiences.
flash rom and switch on airplane mode, then restart. when the operating system booted, turn off airplane mode and everything is back to normal until you restart it again.

hmmm, that makes sense.
I probably left it on when I was experimenting with the airplane mode I'll give it a try later on ,damn this is annoying!
So this is probably a rom issue... I wonder why the sim card change fixes it.

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.

WIFI ERROR \ Turnning on \ Wifi Goes To Grey

Hello Everybody ... Am a new member to Xda site but i learned alot through reading your posts long time ago...
anyway here is my problem MY GALAXY NOTE GTN7000 Wifi Is not Working....
Details: I Had The phone since febraury 2012 and it was GB 2.3.6
i Updated to I.C.S 4.0.3 Official Rom and rooted it in july 2012
suddenly in august 2012 the problem started to appear ((( Am Writing Dates so To Avoid the Possibility of Hard Brick or anything because the phone was working great till then )))
THE PROBLEM
1-When I Try To Open Wifi It just Lag and stop responding The ICON GOES TO GREY INSTEAD OF GREEN and stays like that till Reboot and some times stays grey after Reboot
2- when opening wifi from settings tab it says "Turning On Wifi " and stays like that Forever
3- the only Way To restore the wifi icon to white is trying to activate WIFI - Direct
4- Rebooting Used to fix the problem but now NOT
5- Removing the battery Used to fix the problem But NOW NOT
Fixes I Tried
1- Restore Factory Setting & Wipe Cache & Wipe Everything
2- Changing the Rom from (I.C.S 4.0.3 )to (GB 2.3.6 ) to (Paranoid Android ) to (I.C.S 4.0.4)
Sometimes after each format or rom flash wifi worked for 2 hours or even 24 hours normally then problem appear
3- Tried removing Wpa Supplicant ( Helped Sometimes Then NOT )
4- Tried Wifix TO change country code even manually did it
5- Adjusted the Nfram_Semacove i dnt remember the name actually from CC To All ( Worked then later Stopped )
6- Used Wifi Rescue (Worked for a while then Stopped )
7- I Flashed Alot of kernels ((Heared that syiah Kernal Fix this problem but nothing out for NOTE YET )
HELP
I know that many will think that its a hardware ISSUE BUT IF Its hardware then why sometimes it work !!!!!
What i really Think is : Its a BUG Changed some files of the system which are not restored by flashing new ROM !!! for example when i Flashed Roms and Kernels i Found WPA Supplicant unchanged with my router Config !!!!
I SENT THE PHONE TO CUSTOMER SERVICE AND THEY SAID WILL CHECK AND REPLY within24 hrs but for sure its hardware and change Board which means 2800 EGP which is the price of new SGs2 soo am sure its a Bug or Software CAN ANY1 Help MEEEEEE

I am also facing the same problem for last one month and tried almost all the options tried by you but no relief. Wifi just works some time and other times it stays greyed. Can any one suggest any other solution as i also think it's software problem.

jesus christ, we are not BLIND!
anyway, i have same issues on sgs2

Same issue
@MOHPHR : I am facing the same issue as you.
I tried several ROMs from Original stock ICS to Paranoid to Crisleko's ROM.
Going into the airplane mode and then turning wifi on used to work, not anymore.
3G Data works just fine, not being able to use wifi is frustrating because when I leave it alone, it connects by itself randomly when I am at home for example.
I have done some extensive research and found an article that mentions wifi hardware problems resulting from ICS update on a galaxy S2. (Google: Samsung Galaxy S2 WiFi Issue BY Shaiful Borhan )
I did use the *#*#526#*#* and got the status: "NotSet Driver loaded [NG]".
Anyone can help please ?

Hi, I have been looking for days now for a forum that will be discussing this exact problem. I ve had this issue fora month or so now. I have restored to factory settings but it has not solved the problem. My galaxy note n7000 is not rooted nor does it have any special rom. I wouldnt even know how to install them. Where you able to find a fix? I am so tired of this problem, Im even contemplating the possibility of getting a note 2 and selling my n7000. I believe as well that it is most likely a software problem and im wondering if the soon to come jellly bean update could fix this issue.
Ps: after the wifi problem started, ive also noticed freezes and restars/ reboots.
Thanks for your help guys.:good:

@fedetipito I am still considering the hardware issue, although it seems a compatibility issue with the region/country as @fearkillerr mentioned in this post (http://forum.xda-developers.com/showthread.php?t=1436683)
I tried his solutions, none worked. The script one worked, but only once, then the problem kept repeating.
I upgraded to JB 4.2 then downgraded to stock GB 2.3 still the same issue. I am from the North Africa/Middle-East region, although when I was in Sweden in holidays and using a Swedish sim-card didn't have this issue. Any thoughts ? This problem is really really upsetting as we cannot use the WiFi properly. I am seriously considering simply abandoning my Galaxy Note N7000 and go for an iPhone 5, simply because I cannot even sell it (since no one would like a smartphone that doesn't have a proper wifi working).

I am having almost same problem with WiFi after I installed Custom ROM.
I tried only one method and it worked like a charm.
Go to WiFi connections and tell your phone to forget the network you are connected to, then re log. This problem did not happen after that 3 days now. Good Luck.

@Valium10 we initially cannot connect to any WiFi network, so we can't "forget" them. I don't think it is a "wifi network" problem.

" although when I was in Sweden in holidays and using a Swedish sim-card didn't have this issue"
And if you take SIM card out and power-on phone?Will wifi work?

Sometimes no, sometimes yes. It's kind of a malicious bug.

I am also facing the same problem and it seems it is hardware problem. May some dust or something else on the hardware or else we have dropped our phone some problem is there. When I gave to service center they asked that the motherboard needs to be replaced. But they refused to check it without that. I told that first try without replacing any parts and just check whats wrong in this if some repair can be done, but the service center people are so busy 50-60 peoples were waiting in line behind me to give there phones for service. They do not listen anything. They have tried by installing latest ROM and nothing else, that we can easily do it and for that also they have taken service charges.
Please someone tell me where exactly the wifi module is there, so we can open and check the problem ourself.

Galaxy S advance signal loss problem

Hey I would like to ask you guys using ddulp8 jellybean indian firmware a question.
On gingerbread, this phone had a problem which caused it to lose signal randomly which was fixed by putting network in gsm mode only. this meant that i cannot use 3g.
Now on jellybean indian rom, do you still have that issue? when network is on auto mode, do you have problem with device losing signal or errors like "device not registered on network"?

Nope. Everything works just fine with ddulp8. Btw that firmware is not for my country region but still it works just fine. Make sure you do factory reset after upgrading. If such problem persists, then it's a problem with your provider in my opinion.

the reception issue is quite known for the device, it looses signals in calls and otherwise too often, there might not be any issue with the provider........

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!

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..
