[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] LG Optimus Black internet problem

Well recently i bought a LG Optimus Black, at the begining internet and all worked just fine, and now suddenly i cant connect to internet.
I am able to connect to a wifi network, but 3g wont work, how can i fix this?
Every opptions are right.
I tried the same sim card in Samsung GalaxyS2 and some other phone, it works fine. So it has nothing to do with the SIM.

try to configure your 3g network, look for it on the internet.
i only had this problem when i install NOVA ROM, but it was easy to solve the problem.

I have tried but not helping.

Is it running on Stock ROM or NOVA?
Just like lucasmalaguti said, this problem happens only on custom ROMS.
Anyway, just check your settings.
Settings > Wireless & Network > Mobile Network > Access Point Names
Search on the internet or ask your provider for the setting configuration.
Also, if you have a few Access points, Eg. MobileInternet1 & MobileInternet2, make sure the right one is checked.
Download APN Backup & Restore app from market to delete and re-add Access Point.
Once edited/add, reboot phone for changes to take effect.

Check your APN settings
Sent from my LG-P970

I'm running a stock V10E ROM
My APN settings are OK (sent from my provider)
Tried to manually add it, but nothing helps

Today i called LG Service support.
They say that i am not the only one with this problem.
The problem seems to be caused by automatic software update (V10A => V10E).
Only solution is to reflash ROM.
So i did that and now everything works fine.
Thank you all for trying to help!

I have same problem, how do i re-flash to the old fw
Hi, I got same problem please tell me how can i re-flash my previos fw? thanks.

Hello! I'm newbie
I have the same problem. Please help! What is this ROM? How can I do this? Can this really fix my internet problem? thank you

Had same issue, thought it was the carrier but it could be the phone, hope this helps
1. turn off your OB and take the sim off
2. test the sim's 3g on some other phone
If it's working
3. put it back in your OB = problem solved
It it's not working
3. call your service provider

Fix for many Data issues!!!

I wanted to follow up with a solution to a problem I've had for a long time that I finally resolved, in case others run into a similar issue.
Original symptoms:
- Roaming would transfer no data.
- Forcing to native CDMA 3G mode would not transfer data.
- 4G WOULD work just fine.
- Phone calls worked fine in all modes.
- Signal Check would never display the band like its advertised to do (originally thought it was fault of Signal Check, but its not)
- The Mobile Data screen only had 3 options listed, 4G Settings, Network Mode & Automatic Connections. It didn't list any options regarding roaming, domestic data, International Voice, etc.
- Hands-Free Activation would never work, nor would Update Profile or Update PRL
- Phone would rarely go off of band 25 (1900mhz) to one of the other Sprint bands (26 & 41)
- Popping the sim card in and out while in 3G mode WOULD temporarily fix the 3G data problem, but if I switched to automatic (4G) and back to CDMA (3G) it would stop data transfer on 3G again.
I had wiped, re-wiped, restored from RUU, restored from stock backup several times. Also tried updating radio firmware and PRL using ADB and MSL codes. All to no avail.
Then I did the following... I'm not entirely sure which of these steps actually made the difference, but the following process resolved all the problems above:
0) Did a Titanium Backup of all my apps, and booted into Recovery and did a Nandroid Backup.
1) Booted into Bootloader and ran Factory Reset from HBOOT (Bootloader). Since I have a custom recovery all this did was launch my custom recovery (TWRP), but perhaps it makes a difference going through the Bootloader rather than booting directly into Recovery?
2) Under wipe, ran Factory Reset.
3) After this ran, I went to advanced and wiped Cache and Dalvik again, even though this is already done once from point 2.
4) My backup of my stock image is actually in two parts. So I ran the first restore, then AGAIN cleared Cache and Dalvik.
5) Then I ran part 2 of my Stock backup, and AGAIN cleared Cache and Dalvik.
6) Reboot
7) This time, for the first time ever, when the phone booted the first time it ran hands free activation and was successful, as well as PRL update. Had the phone for several months and this is the first time since the original out of the box activation that it was successful.
At this stage I noticed all the new options under Mobile Data, and tested 3G and it worked! Woo hoo. unfortunately I run a custom ROM so I wanted to put that back on. So I went back from step 1 and did all the steps again but instead of restoring stock I restored my ViperOneM8 ROM. The results were still successful, so I then updated my PRL and Firmware to the latest stuff, forced roam, tested it, forced native 3G, tested it, everything works great. Also now Signal Check correctly displays the band I'm on, which it never did before. Also, my home tower always had me on band 25 before when I looked in the Engineering screen, but after fixing this I'm now on band 26 (800mhz), which is great.
SOOO.. I think from all the things I've tried in the past, the new things that might be making the difference is either:
- Factory Reset initiated from Bootloader
- Cache & Dalvik wipe before and after any Restore.
I've installed ROMS, firmware, used ADB, used my MSL in with various resets, etc. So I figured I always knew what I was doing, but I think one of the very simple things above makes an important difference. Just not sure which step it is, but apparently the little things count.
A couple other related things that users with similar issues should try if this doesn't help:
- Make sure to Update Profile and reboot
- Start a web-chat or phone call with Sprint and ask them to force a Profile Update from their end. I've had success with issues with them initiating a profile update.
Hope this helps others!

I am very happy for you and will try the same today, what new settings did you see under mobile data?

Data roaming sound, roaming guards, roaming, domestic voice, domestic data, international voice, international data and 3 grayd out ones: allow GSM data, access point names, and available GSM networks. Probably disabled because I'm on Sprint (CDMA not GSM)

How do you get to the engineering screen?

I use signal check, and there is a shortcut in that app that launches it.

Sorry for necroposting and being a noob, but this required rooting, right? Could you walk me through it in a little more detail? How to boot into recovery, bootloader, etc.

depends on the phone. I'm only familiar with the M8

First things first, the information in this thread is NOT required to root or unlock the bootloader. There are threads with that information in the general as well as Q&A threads and even the development thread. Also, if you search the internet for HTC DEV you will find their website and they give instructions on unlocking the bootloader.
With the M8, the first step is unlocking the bootloader, then you install recovery and from there you can gain root privileges.
You can also use Sunshine to unlock the bootloader and obtain s-off which is not required to flash custom ROMs, but other firmwares and radios.
Please be aware that unlocking from the HTC dev website will wipe everything. Including pictures (and anything for that matter) stored on internal storage. Sunshine does not.

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..

LTE and 3G stopped working?

Hi guys.
So a week ago my Mi5 only want to connect to edge, the LTE and 3G simply wont work.
I tryed everything, forcing it to only use LTE = No connection - same goes for 3G
I have also tryed to reset APN settings and nothing. I contacted my carrier, and they told me everything was fine.
I just tested it in my old Meizu and the LTE works fine. Anyone know what could cause it?
Please help, cause as for now the connection is so slow that without Wifi it might aswell be a flipphone...

Update: I also tryed to install a stable rom using this method: http://en.miui.com/a-232.html
But i cant, i get the "Your allowe to flash the newest stable rom from develop version ONLY"

Try this:
1. In Settings/About phone/ press several times on Internal memory
2. Press Phone information 1 or 2
3. Scroll down and Set Preffered network type as you see on image or chose LTE Ony .
4. Wait few seconds till change has effect.
