Month àgo my 3g used to be working, sudenly my 3g change to 2g.
I checked my settings and everything was fine.
I putt my sim in another phone and the 3g worked, so its not a sim problem.
My apn setting are good.
I tried everything and nothing solved the problem.
What can it be?
Check Settings - Wireless and Network - Mobile Networks - Network mode, it should NOT be GSM only. Try setting it to WCDMA only.
.
I already tried it. If i putt it on wcdma only i dont get any connection.
Backup data and then factory reset .
jje
How do i do factory reset?
Backup your data and apps using a program like Titanium Backup, then go to Clockwork Recovery and select Factory Reset/Wipe (or something similar).
I did wipe and change my rom few times and its doesnt work.
Dont know what rom you are using but i would try installing stock froyo via Odin .

Make sure that HSPA is activated on your phone by dialing *#301279#

Have you tried flashing a new modem at all???
Sent from my GT-I9000 using XDA Premium App
Not yet. I dont know what kind of modem to flash.
If its your standard Galaxy S I9000 you should be able to flash any of the standard modems. I use JPY because it seems to have the best signal and battery life. If you search the forums a little you should find out how. Darkyys ROM uses it as standard

I have the same problem and I just repartitioned in Odin to JS7 and it still won't automatically go to 3G/HSDPA, I have to force it either through setting it to WCDMA only and then back to auto or through SGStools by setting it to WCDMA 1900 only and then add the others in combination bands. All of the APN settings are correct, my IMEI is still the same, my HSPA revision is set, phone information states WCDMA preferred, I've factory reset, cleared cache, cleared Dalvik cache, and as I mentioned earlier, flashed with repartition, and after all of that... I still have to force HSDPA access.
Hi guys,
So I had this problem before, but the Captivate magically fixed itself. This time... not so much. Or not yet anyway.
Upon boot I get a "No network" symbol. Sometimes it shows the bars on boot, but quickly reverts to the no network status. I just flashed the newest version of Cognition with the accompanying kernal. I have bounced around through various roms and kernals all night, but the problem seems to carry over (even after wiping the data/cache/return to blah blah).
Any ideas?
Try some other modem......

Crispy1805,
Try going to Access Point Names and tap menu then Reset to default. Once it populates at the top of ur screen, tap the dot, it will turn green and u should be good to go.
Menu/ Settings/ Wireless and network/ Mobile networks/ Access point names/ then menu/ "Reset to default" then tap the dot selector. Reboot should not be needed.

Apn are for data right, is this anyway related to connectivity to the network.
Yes, you need to be accessing at&t's access point to connect to it's network...
Hm, tried that, no avail. The problem is that it is not detecting any "bars" at all. I removed the sim, same problem. My Infuse is showing bars in the same location, so its not a network problem.
Did you make a backup of your efs folder you can restore?
Good point, let me check and try that if I can find it.
gah, I cant find it.
Try this http://forum.xda-developers.com/showthread.php?p=15158920 ... Use the 3 file version. It is kf1 stock, but the kf1 came with a seperate CSC .tar file and the kf1 is a full wipe... Worth a shot. But u need to already have the i897 bootloaders.
If this works, then u can move on to kh3 or whatever u r wanting to go to...

I flashed back to stock (enclair---odin 1 click and master clear), but it is still not showing any network /bars. I tried this --
http://forum.xda-developers.com/showthread.php?t=881162
but all of the values were already correct. When I check for an IMEI it says "not registered on the network" --- but it can't SEE the network as far as I can tell, so that makes sense. Perhaps the network card isn't coming on at boot?
Any more ideas?
This had happened to me recently, Some how 1 of my captivate lost the original imei and had the generic one 0000461090000, When u chek under the status it shows the details but no connectivity. I restored the imei and all ok.
Mine has its generic IMEI. It was sim locked for some reason, but I fixed that--- still no signal , just the blue circle with the bar through it. Under status:
Network -- Unknown
Signal Strength -- 0 dBm 0 asu
Mobile network type -- GRPS
Service State -- Out of Service
Roaming -- Not Roaming
Mobile network state -- Disconnected
Again, the Infuse right beside it is picking up signal (2 bars of "4G" i.e. 3.5G)
Update: Flashed to 2.3
Now the signal strength -- -111dBm 1asu
The rest is still the same :-\
Generic imei does not works in India we cannot register without a proper imei but it works in US members here have confirmed this. Check your lock status with *#7465625# what it says.

Just out of curiosity...If I make a backup of my efs folder now while running the FASTY II (KH3 i897 ROM) then flash say, Rom EPIC (JVS I9000 ROM) and end up having no network (This actually happened) will I be able to successfully restore the efs folder without having any problems?
Yes you can restore it.
Do you think its an EFS folder problem? I am clueless at this point.
Code:
You have a generic imei and it is quite possible the problem is coz of that.

No, I do not have a generic IMEI.
Hi!
Resume:
My note has some weird problem with the modems. I'm getting "Unknown" baseband, modem verison, phone number, IMEI etc. with all the modems I tried except one, which shows the correct IMEI and modem version but still not working(I can even see the mobile networks with that one, but I it doesn't connect and gives me "Refresing SIM data" messages).

I always have been using custom roms(only TW) and updating my note to the latest version and I never had a problem.
One day, some months after the last rom update, started to lose the phone network conection and I was getting pop-ups with "Refreshing SIM data"(was very annoying because that was turning on the phone screen every few minutes). Sometimes I had phone network and sometimes I hadn't. The disconnections became more frequently. The phone also started to eat up the free space for apps, so I had to remove several apps to install or update even a small one.
So I decided to change to a different ROM to see if that fixes both problems, but I got the actual problem.
I was in AllianceRom v3 JB when that happened.
I flashed this AryaMod 5.5 JB following their instructions and I got this weird problem. In the "About phone" says that the Baseband version, IMEI, IMEI SV, Network and My phone number are "Unknown". I can't even search for mobile networks because it says "Insert SIM card" when I try to open the Mobile networks menu. Tehre are no signal bars, only a "denied" icon on the status bar.
I tested all JB modems and some from ICS from the "all modems" thread, but I was getting the same "Unknown" things in each one, except the XXLSO, where the Baseband version, IMEI and IMEI SV were okey. I could also find mobile networks with this modem, and the "Refreshing SIM data" thing returned, but it was not possible to connect to a network. With this one, there aresignal bars, but they are empty.
I flashed the AllianceRom and even the old ICS rom I had before, but the problem persisted, even with the modems they came with.
Now I'm on the latest Samsung rom(LT4), unmodified and flashed with odin and the problem persist.
I found this old thread. His initial problem is very similar to mine, but they don't know what caused it nor how to fix it.
I have also found something about corruped IMEIs that you can fix doing something with the ADB and restoring EFS folder, but I think that is not my case because I can see my original IMEI with the XXLSO modem (and I my EFS folder looks OK, anyway I have no backup of that).
I don't expect to get a step-by-step tutorial about how to fix this, but I hope somebody can put me in the right direction. I will post the solution if I find one!
What are the first 4 digits of your imei

Thanks for reading, the four first digits are 3595.
Maybe this is a stupid question, but have you tried re-seating your Sim card, or even a different Sim?
Sent from my Nexus 5 using Tapatalk
I tried both. Also I have been using the SIM with another phone for weeks and works fine. Tried to take out the battery and wait few minutes and other "stupid" things like re-flash a ROM, re-wipe all, etc..
Maybe it's the programed obsolescence, you can use the Note as PDA but if you want a phone, go and buy another...
@ThaiDai or @nokiamodeln91 I believe knows of a way to fix this if its an EFS issue...but you don't have a developer imei
Did you have an old efs backup from when u first rooted your phone?

If it was a corrupted IMEI issue then it should not come back when the xxlso modem is flashed.. And also not sure why it goes to unknown when any other modem is used.. Could there be any physical damage to the sim tray? Dropped the phone?
I have no backup of efs... I had one "nandroid" but deleted it after everything was okey...
I could delete the efs folder, so this unknown problem will turn a known one :victory:
I dropped the phone a very few times, maybe in one of those something broke a little and has increased more with the usage? (the disconnections from the network became spontaneus and progressively).
I found this other thread, I could try the same but I can't find the original GB firmware, every link I find is in hotfile.
Check in Samsung-updates.com firmware section. There are 2 GB roms there..
I found a efs backup from may 2012, probably auto-created when first installed ICS.
I flashed the stock GB rom and restored it following this tutorial for my .tar.gz file, but didn't work, so the device may be lost. I only have 3 more backups: boot.img, data.ext4.tar and system.ext4.tar. I guess they are useless to fix this...
Thay you for you support!
I have a HTC J ONE HTL22 and a few days ago I lost my network signal completely. Contacted my network provider everything was good,bought a new sim tried that and still no network. The day I lost it I went into the service menu #*#*4636*#*# and into Phone Information and was just trying some different network settings. I clicked select radio band...and I saw Euro Band,Japan Band,US Band ,AUS Band ,AUS2 Band. I tried US Band to see the result and than i lost that menu ,now I only see Automatic, Cellular(800-MHz Band) and PCS(1900-MHz Band). When I try Automatic it says Unsuccessful. The other 2 successfully work but don't give me my network back? I've done a factory reset and still nothing changes. When I manually search for a network,it comes up blank. before it showed Bell,Telus,Rogers etc. So it's defiantly something with my radio.
My cell is UNLOCKED, S-OFF, CID-11111111, HBOOT-1.54.0000, RADIO-1.23.11.0829 and CWM installed,running stock 4.2.2. So I'm wondering is there a way to reset my radio or any help on flashing a new radio? Thanks

Thanks for the link. Today I tried to install a new radio through CWM. I pick the zip to install and after a few seconds it says complete...I reboot and my radio never changes. I've tried it through CWM and Rom manager. Am I doing something wrong?

This might be of a bit more value. It seems the prior link was for a different HTC One model. Above link is for M7. Check it out if you still need a radio/baseband.
I also realized your phone is a Japanese variant...I dont know if that makes a difference or not in compatibility, but I wanted to mention you could try using ADB to flash the radio/baseband instead of using recovery. I think you could also upgrade your firmware,which usually includes the baseband. Good luck...
Thanks for reply
Nothing help
flash radio through fasboot and TWRP does not matter
Same here...still no luck yet. Still have no network. Makes no sense why the radio bands cant be restored!?
many service centers, many ROMs nothing help
I am a proud owner of a mi3w and for the last 3 months I have no 3G reception. My phone works flawlessly if I change to 2G only, but when I switch to 3G only I lose reception completely. The problem started a little while after updating to the MIUI 7.0.5.0 stable international. Can it be a harware or a software problem?
I already tried reflashing ROM (through the selection of "return to factory settings"), clearing cache, updating to 7.1.1.0 and my sim works in a different phone receiving 3G and 4G. Any help would be highly appreciated.
Have you tried to search network manually?

Yes I tried both 3G preferred and only 3G. Moreover I tried to connect ot the 3G network but the problem remains. Can it be a hardware problem since the antenna works with 2G?

IDK. Also I don't know if Baseband has to do something with reception. If it does, you should flash MIUI MM. It updates Baseband version from 3 to 4.
use "fastboot flash modem" and then filename.ext
