[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.

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.

[Q] No network after kernel change and/or formating

Hi,
on my xperia X8 i was changing ROM's to test them and i was using GingerDX for a while. It was good, everything was working like a charm. Then my friend poked me with CM9. This one
As noted in that thread i needed nAa 11 kernel that i installed (correct if Install is wrong term). Kernel was installed nicely. CM ROM from that thread was working nicely, as stated camera and wifi don't work. But i also don't have network. My SIM card is locked by provider, i enter passkey and i get standard unlock message. That's OK and it proceed to home screen. Then i notice that i don't have network signal and i got SIM icon on my status bar (as noticed in Pic's).
So firstly, to see what is what:
I guess my phone is bricked, i bricked it lots of times and fixed with SEUS.
CWM is 5.0.1.2 and also xrecovery (i can't remember version)
I put another kernel, something "linux" something...
After "IDK what not" i tried S1tool, SEUS again and again and again and still nothing. I manage to take it back to stock rom with nAa kernel, nothing. Stock ROM with stock kernel, nothing... On stock ROM 2.1 i get to unlock SIM, do that and it just shows status bar, no menu, no widgets, no home screen, not even launcher. On status bar: SIM icon, signal icon (empty), battery ofc.
On that CM9 ROM i can do everything but still no network and WiFi don't work as mentioned and stated in Luke's thread.
So i cant go on nor back...
I'm working on phone while i write this and i have no clue how i made it to work...
It's fixed, on stock rom but network is working.
So, i wanted to ask you how to fix it but now i want to ask:
What did i do to make it not working? and
HOW did i fixed it?
I've been working on it for like 20 hours and i have no idea what did what and when.
If you need some pictures i will be happy to post them for more information on the problem.

I dont have that ROM on my Phone but i saw some ppl fixing it by simply going to Security --> Simlock --> Unlock SIM Card (or something like that).
As far as WIFI is concerned i am sure u know that it needs static IP.

I beleve it was radio. I now installed both GingerDX and that CM. I have network now. And WiFi works with static IP. Thank you for posting

[I9295] Cellular not working

Hey guys,
in the beginning, sorry for my bad english (native german). I have a problem with my I9295 aka S4 Active. Since the update to 4.4.2, my phone gets thrown out of the network. Wlan and Bluetooth is fine. Now I flashed the official Samsung DOB4 firmware. Yes, I've downloaded the file multiple times, and the md5 sum was always right. After I flashed it, I was very happy because my cellular network was working again, I could make some calls, etc. But after 20 minutes, it started again. No network. Well, my IMEI was null, and to fix it I had to root. After rooting, my IMEI is there again (yes, the right one) and everything worked fine and was still working, up to yesterday. IMEI still there, baseband too, everything seems fine, but I can't get network. I have to reboot multiple times to get it working again, after that it's working maximum a day, after that, no network again . Atm, i've flashed CM12, but the error is still occuring. I'm very desperate, I hope somebody can help me.
I have a quite similar problem:
My I9295 loses service randomly. Happens quite often.
When I try to go to Settings/More Networks/Mobile Networks I am told "No SIM ..."
SIM is in and had been active. Phono tells me I have network reception.
After reboot it works for an hour or 20 minutes or whatever it wants to.
Sometimes it reconnects after a while, sometimes not.
When I leave it on during night netx morning reconnect works only via reboot.
SIM reader had been replaced.
Problem persists with genuine 5.0.1, with this one: [ROM][Official Nightly CM12/Unofficial CM12.1][5.0/5.1.1] builds for I9295
and WizCyan ROM.
Any suggestions?
BTW I use a TWRP recovery
Possible reason explained here
http://forum.xda-developers.com/showthread.php?p=56955843
Enjoy
Thanks for the hint.
Not sure if I get this. The problem was also there with the genuine Samsung ROM (lolipop)while the thread talks aout losing modem function after flashing custom ROM.
About previous I am not sure as I bought it used with 4.2.2 on it.
I updated to 4.4 and then 5 OTA, all genuine.
Only because the mobile kept on losing network I switched to custom ROM, but the problem persists.
At the moment I use the Pac-Man ROM 5.1.1 where it seems to be more stable.
Strange!
@augek
The linked thread isn't only about custom roms - you can end up with partly flashed baseband on genuine if you don't power off before download mode and flash using Odin.
Was the replacement job of SIM reader done by a qualified person?
Following your Suggestion i flashed the genuine lollipop with odin. Yes i switched of Prior to flashing.
And Yes the Person Who did the card reader Job is qualified.
Still the Problem persists.
So to me the question is if the Firmware (driver) is the Problem of my sim card. The sim i tried on my s4mini and doesn't cause Problems so far as far as i noticed.
P****es me of somehow.

No SIM signal or wi-fi after update

Hi everyone,
I have a big issue with the xiaomi.eu Miui 12 20.7.2 and other after this...
After install in my phone (Mi 8) I dont have access sim card. Is like that I dont have any sim card. And no wifi to.
I've done first a dirty install and after a clean install but the problem continued.
After I was rollback to the 20.6.18 version where all works fine! if I upgrade again the problem still the same...
What can I do?
Thanks
Same issue
Hi, I have the same issue, in my case that issue started once I installed Miui 12 20.07.16. I tried installing other ROMs without fix this problem, I will wait until they deliver a new version waiting they solve this problem.
Which TWRP did you use to flash the rom?
I don't think it is a software problem if you have the following symptoms, No WiFi but Bluetooth, no service but detect SIM card, random reboots out of nowhere or when trying to turn on WiFi, unknown baseband and it gets hot, apparently it is a processor SoC solder problem
