[Q]error while searching for networks

Hi.
My HTC magic doesn't find any network (while in 2G mode), this happened out of nothing.
I tried everything, updated my ROM, my radio, my spl (now I have android 2.3.4).
Nothing worked and I really don't understand why.
I also tried puting the new libril.so and librilswitch.so, and didn't even asked me for the sim pin anymore.
I even tried the gfree method explained here http://pheide.com/go/blog/computors...arching-for-networks"-on-unlocked-t|mobile-g2
I also tried a new sim card.. still not working. Please give me a solution, someone, a developer or anyone. thank you
PS... When travelling a dont often have 3G network, so I can't use the phone, even if other people have a full service.

The error is the one in the title, and sometimes I get, cannot connect to this network at this time.

so nobody's helping me?
i've updated the radio from 2.22.19.261 to 2.22.27.08 and the issue is the same as i said, can't find network in 2G mode. (for example in the country side)
I really need it to work also in 2G and 3G mode, some help?

what is your radio set to in
*#*#INFO#*#*
...
i had this problem when i tried a different kernel
my solution:
full wipe in recovery
reset to recovery
full wipe in recovery
flashed last nandroid that worked properly
let the the system boot and see if that fixes it

thank you svpb for your reply. In *#*#INFO#*#* I tried everything, wcdma only, wcdma preffered, gsm (auto), nothing worked since it always chooses 3G, but when there was no 3G network, i was out of signal.
So, I decided to put back the original radio, the 2.22.19.26I (always tought that the last 'I' whas a '1'). So, I downloaded it from http://code.google.com/p/superatmel/downloads/detail?name=ota-radio-2_22_19_26I.zip&can=2&q=
And yuppy, it worked, no signal problems anymore.
I tought about what you said, and i tried a lot of kernels with different android roms 2.1, 2.2, 2.3, but I thing the radio software was broken or something.
LE: I am still wondering why it didn't work with 2.22.27.08 radio, but I'm glad it's good now.

Ok, it seems like it didn't work. The 2G network is not working again.
As I said in the first post, the error started out of the blue, I didn't change anything that day. Could it be hardware wise?
Other thoughts?

rom with GSM radio , the phone worked fine when on 3G but when it couldent get 3G the phone would fall back to GSM 2G , and of course the phones 2g radio was cdma so they got no reception.
i am on rogers gsm and i always have my phone set to (GSM PRL) and find it gets good signal.
hsdpa and wcdma is a designation for 3g
also WCDMA and CDMA are completely different
(someone correct me if im wrong)
i would also look at setting it back to factory and see if you can get a warenty repair (if you qualify)

I no longer have warranty.
could you recommend me a radio? working radio, that is compatible with 2.2.1 (currently I have kernel 2.6.34.5-cyanogenmod, build no FRG83)

Mobile network not available

Hey, last night I managed to install cyanogenmod 7.1 on my GT-I9000M. The purpose of this was to root the phone, so that I could SIM unlock it. I ran the free unlocker app by helroz, and it didn't make any complaints, so assume it worked.
As you'd know, the GT-I9000M variant is from Canada, but I live in Australia (Bought it off a friend). I tried putting my SIM card into it, and it does tell me my carrier (Telstra), but the reception bars remain greyed out, with a little x up the top.
When I try make voice calls, it says "Mobile network not available".
Does this mean the phone is still SIM locked, or could I be doing something else wrong? Is there a way to check if it's still SIM locked?
I have taken a few screenshots that may help:

You need to flash KG3 modem.
Here's the link to the post by [Ramad] with modem for i9000m.

Hi, thanks for the reply
I'm trying to do that now, through Odin. I put the .tar.md5 file into Phone, and went to flash it, but it failed. It seems odd that the file has 2 extensions, is there something i need to do to it first? (Most modem files I've seen have been .bin files?)
EDIT: Nevermind, managed to get it to flash. However, now the phone won't pick up my carrier at all, and baseband version is Unknown?
Regards,
Dan

Maybe try to flash it in recovery mode?
Here's one for CWM.
View attachment Modem_KG3.zip

*ignore this post*

Bell i9000m by default is 850 or 1900mhz , try to change it to 900 or 1800.
Dial *#2263# and in GSM menu choose either of em.

Dialing *#2263# doesn't seem to do anything
I've installed the new modem you linked me, it still says "Telstra", however still no reception apparently (I know I do get reception in this room, and the baseband version seems to be the same)
Regards,
Dan

Same thing happened to me I had used the wrong version of cwm to install the rom. All I did is reinstall with the cwm that the rom had installed itself and everything worked fine .

I just tried reinstalling cyanogenmod from it's own CWM, but still have the same issue.
Just looking at the phone now, it seems the signal strength is always on -111dBm and 1asu, doesn't change.

Dan

Sorry the sane fix didnt work for you .I moved to darkysrom myself because of so many missing features in cyanogennod like the tv out feature.
Sent from my GT-I9000 using XDA Premium App

Yea, I'm wondering whether the radio hardware itself might be broken. It always shows no service with this SIM, no matter which modem version I use, which firmware etc. Signal strength always shows -111dBm 1asu and that's about it.

Flash a GB firmware with pit and repartition, I think that you need to do that when flashing back from CM firmwares, then see if the device functions properly.
Check if the IMEI-number is not changed, if it's not changed and the device still can't detect the SIM-card then try executing on Terminal Manager (from Market) or using ADB (su and busybox must be installed on your device):
su
busybox chown 1001:1001 /efs/nv_data.bin
reboot

If the device detects the SIM-card but the device gets no reception then flash a modem that supports a different band, UGKG3 for I9000M supports 850MHz and the modems for I9000 supports 900MHz out of the box.
The idea is to try to narrow the problem down to 1 point, you need to know which modem you need and you also need to know that your device is not defect, doing that using CM is not the proper way, use stock firmware to avoid possible bugs in CM, and you don't need to flash to Froyo in order to flash CM, you can do it from GB by flashing a Kernel with CWM support and you are good to go.
Good luck

Hi, thanks for the detailed reply.
I've just flashed back to the stock GB 2.3.3 firmware, however I'm having trouble figuring out how to install su?
With the stock firmware, it doesn't even tell me my carrier anymore, and just says "No service".

Dan

software unlock

I did the software unlock via the dial code & UMTS menu, I can make phone calls with a different carrier sim, but I cannot get the data to connect. I have been searching xda and google for months trying to get this to work. I have a Canadian Bell mobilty i337m. Stock rom (mdj) and its rooted. I have tried factory reset several times but it doesnt fix it. I also tried flashing back to stock with odin. Does anyone have any other ideas?
When I try a telus (or other provider) sim, it give me voice service only and in the about > status menu the mobile network state either says disconnected or connecting. I have the data toggle on also.

Those unlocks don't work that well with the Canadian variants. They're designed for the i337 not the i337m.

Have you made sure the apn is set up right for the carrier?

Maybe this will help
Code:
http://apn-settings.com/canada/apn-settings-bell-mobility/

I will say the reason that cause the problem is that this is an ATT phone with At stock ROM. So it doesn't have the APN setting for other carries. You should set that by yourself.

Not true. I successfully unlocked my first S4 I337M on Bell following this tutorial. I sold that one because I was able to make a profit once I unlocked and flashed the AWS mod to make it compatible with WIND and Mobilicity.

Try reflashing the original 4.2.2 firmware from here and then immediately follow this tutorial before rooting (do not install any system updates!). Then you can root, install custom recovery, reset the flash count, etc.

You did exactly what I am in the process of doing. I will try what you suggested now. Thanks!
Also, ive manually inputed apns for telus and eastlink and neither seem to work. I can always make voice calls, but the data will not connect.

oddly enough, when I put a telus sim in it and waited for a while (in hopes it would eventually connect to data) and the apn settings for telus were in the phone. I know I didnt put them there because the apn settings for koodo were also present along with a third apn that I cant remember.

For future reference, try not to double post. Just edit your current post.

It's actually not an odd thing to happen. Once an activated SIM is inserted and the phone is unlocked, the phone searches for the best APN settings from all compatible carrier bundles. Some phones do this more accurately than others. However, it may not do this well enough if a custom ROM is installed. I know this to be true because this happened with my older Galaxy S3 when I tried selling it to someone (it was a T-Mobile unlocked running CM 10.0 at the time). However, setting the APN manually (assuming all settings are correct and that nothing else is wrong with the phone) should resolve your issues.
If you're still having problems, I suggest doing these things:
1. Try going into your network operators and let the phone search for carriers nearby. Once the list shows up, tap on Telus and wait until that screen closes on its own.
2. If you can't get data going yet, try disabling it, re-enabling, and reboot.
3. If this still doesn't work, try going into the network mode screen and select GSM/LTE and reboot.
4. If it's still derping on you, then it must either be your SIM not connecting to Telus's data network, or your account has a data block. That's all I can really think of.
Good luck.

Ok, reflashed stock 4.2.2 (the first one) and manually entered TELUS apn settings from the telus website, got data to connect finally. As a note, there was a typo in the apn settings that it auto aquired for telus. Going to try a eastlink sim tomorrow and hopefully AWS is working.
Edit: all seems to work. thanks everyone!!

I need help, strange problem

Hi.
I commented that I have a strange problem with my S7 Edge G935A, I have inserted 2 different SIMs, one uses the 900 band and the other uses 1900, the first only increases 2G and according to the characteristics of the G935A it says that it has the 900 band in 3G and 2G but I do not know why he only grabs 2G. And the other one only uses data, I can not make calls or send messages, I only use data and I surf the Internet, I attach the capture.
Hope someone can help me.
Note: I am stuck on the Android 6.0.1 version with the Security check May 1, 2016, Baseband: G935AUCS2APE1. And I never received the notification to update Nougat.

So you're asking why you can't update your phone? At least that's what I got from this. If that's the case why not just manually update with smartswitch, or odin the files onto your phone?

I need to update and fix why doesn't work this bands 900 and 1900. Maybe updating fix this, right?

possibly, download smartswitch hook your phone up and see if smartswitch can find an update for your phone, otherwise you need to download the firmware manually from one of the forum posts here and then odin flash it to your device (make sure to back up your phone as it will delete everything)

That isn't the problem.
But I have news, I installed update for 935U in 935A, and unlock the band 900 in 3G, but still not working bands 1900 for calls and messages only work for data.

Try removing your sim card... Boot the device... And see if the mobile radio can turn on with no card installed...

Did this happen after you updated to 9.0 Pie? Because My phone (Sprint model, flashed firmware to unlock) didn't recognize mi SIM after I took the update.
Where did you buy the phone? Are you absolutely it sure it was not a Sprint phone?
Anyways, I had to flash back to an old firmware, flash a couple of modem files, and now my SIM is recognized again.
I did what this gentleman did...

sprint lock shows "invalid sim" if i'm not wrong , mine is unlocked version and i did ask sprint "i will attach their reply"

had issues calling only certain people and as someone metioned i tured off the " enhanced 4G" and it works fine now, my carrier supports it but it seems buggy...maybe need a we need "official carrier" for it tot work right.
im personally on Tmobile and everything works fine now. I guess its called HD or advanced calling that i had to disable. i attached screenshots. hope it helps someone
