hi guys, just about 2 days ago i rooted my phone. problem is after rooting my phone can't seem to get a 3G signal anymore. only GPRS which is so slow! need help tried reflashing with a stock ICS ROM and still no go.
EDIT: here are the things i did before i noticed the disappearance of 3G
1. downloaded recovery and kernel from tegrak's website.
2. booted into download mode and flashed the recovery.tar file
3. booted to recovery mode and flashed the .zip file
4. installed Tegrak Kernel & Superuser from Play Store
*this is when i noticed that i can only get GPRS/1x signal
what i did after was kept flashing a stock ICS ROM. nothing happened to fix the 3G problem.
searched the forums and none of the method works. tried reflashing stock ROM still a no go.

already did sir, still no 3G signal. i'm 200% sure my area has 3G.. it even reaches 3.5G on my other phones.
okay.. just noticed minutes ago that my other phones are getting up to 4G signals too. and my Galaxy Note can't even get to 4G? its really stuck at GRPS speeds. the root must've messed up something because this is my 3rd reflash of a stock ICS ROM and still stuck with a G signal when data network is turned on.
EDIT: been lurking around xda-developers forums now, even tried other websites... is it possible that a kernel flash could change the radio of the device? reflashing for the 5th time did not do anything for me. after 5 tries (i know, that's too many to figure it out that it doesn't work), i've given up. if anyone has a solution to this problem please message me.
ok guys after a few days of testing. i finally figured it out.
for some very odd reason, this particular sim of mine says "network type: GPRS"
i tried different sim cards of the same carrier (i repeat, the same carriers) and it says "network type: UMTS"
even tried different sim cards from other networks and it says "network type: HSDPA"
so that is very odd. did flashing ruin something on this simcard? i can't really pin point?
anyway for me this problem is solved. i'm getting another sim card hehe. hello again 3G/4G!
EDIT: I FOUND A SOLUTION! its not the simcard, its the band setting! i just switched from GSM to WCDMA and it worked for that sim! there is a secret SKT Telecom menu for the Korean android phones that lets you change the band.ü

Ok so I've been reading around in a few threads about this but haven't quite found a solution in my case and I think I need a second opinion. I've also posted in other on going threads but it just gets lost in the rabble so.... it now gets it's own thread.
Bought a brand new Bell SGS2 from a dude on Kijiji. It was brand new, still in the box with the plastic all on it. I SIM unlocked it (which required rooting it) and dropped my Rogers SIM chip in.
I can send/receive txt's but 3G data drops frequently and usually happens once I initiate a data session. My test case uses SpeedTest. I've only seen it complete a full test cycle twice... most of the time, it will get the ping, start the download test and 10% in, the data connection drops and 3G/H+ icon disappears. It takes about 1-2 mins for the data connection to return. I've tried market access or web browsing and same thing happens once a data session initiates.
I've installed a slew of modem/ROM combinations via Odin from XXKH3 to XXKI4... nothing... same issue. Seemed worse with KI4 too!
I've tried different APN settings, disabling fast dormancy and specifically trying to enable only HSPA bands. Nothing. Same problem.
I've since reverted back to stock BELL firmware and tried a friends Bell SIM chip and noticed THE SAME thing happening! So this would definitely tell me it's a hardware problem. It's been more than 15 days so Bell won't even talk to me as the return period has passed and I'm not a bell user so screw them.
I guess at this point, I should test my luck with Samsung but it's been rooted and even though I've un-rooted the binary counter shows 2 which means.... I'm screwed for warranty right?
U can reset the binary counter after flashing back to it original state by using jig. Google for galaxy s2 jig
Btw, why dont u just flash original samsung I9100XXKI3 rom? Which provide good modem. Check my signature, 'boot loop', theres a link lead u to installation guide with download link provided. All is there.

I personally found XXKI3 Modem to be best for Bell's SGS2 (currently using it on Telus).
Tried all the modems' including KI3... didn't work.
In recovery mode, fix permission, reboot and check the 3g again.
Try another method, flash cm7 nightly latest version #16. If the problem still exist, thats mean its related to phone's hardware.

Well I got it new out of the box but I had to SIM unlock it which required rooting and etc....
I did power-volume up-home... got into recovery mode and... there is no option to fix permissions. Keep in mind this is the stock ROM I put back on.
CM7 is another idea.... not against that.
Well. Maybe some failure occured during rooting your phone before. Install rommanager app from the market, open then select flash recovery mode, then select your phone model.. This will give u recovery v4 which will give u more option on recovery mode. This is the easiest way to get more option cwm. U will have fix permission option when u done.

i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.
Please help, I just installed the latest build Cyanogenmod 9 on my Galaxy S3 I9300. Everything works fine except that i can't get any kind of mobile data. I can make phone calls, send and receive sms but simply there is no 3g/HSDPA connection. Not even edge. I even tried changing my modem firmware and still nothing. As you can see in the image it recognizes the network and the type but it doesn't manage to connect. Am I missing something?
Are your network settings correct ??

Get your network settings manually from your provider

Hello guys,
I have a severe problem with my SGS2.
I was using it as always when suddenly my signal strenght dropped down to 1 bar and since then it's changing between 1 bar and "no service".
I have been running on CM10 Nightly 20120910, thus I thought I'd try another modem. Flashed XXLQ6, nothing changed.
Then I flashed the 20120908 nightly - no change
flashed CM9.1 with XXLX/XXLW modem - no change
reflashed CWM Kernel - no change
I tried using another Sim-Card which operates in another network - no change, still only 4% signal strenght (looked up using Network Signal Info)
The I tried using my current Sim-Card in another mobile phone, and there it worked flawlessly.
WLAN is still working, but no GSM/UMTS. Even if I have 2 connection bars for some seconds, I still have no internet connection via UMTS during that time.
Anybody got an idea?

I'm facing the same issue. Did you solve it?
If it happened suddenly and the problem persists in other phones, than it's your network operator cell.

The problem doesn't persist in other phone. I've tried the SIM in two other phones and it works perfectly.
Also tried another SIM(which works on some other phone) but don't work on mine.

Hi!
Since you are new here, it may be the best time for you to read the forum rules not that you've done something wrong but just to inform you about it
Here's the list of modem that you can flash http://forum.xda-developers.com/showthread.php?t=1131950, it comes along with a guide..
Since everything you mentioned failed, i suggest you flash back to stock firmware and do a factory reset it might just do the job..
i hope this helped you, cheers!

update:
Upon your insistence, I flashed the official stock again, did a factory reset. Still facing the issue. Flashed two different modems again. Still no luck.
Restored by original EFS, no luck. Fixed RW of EFS folder. No luck. Still the same issue.
Please help.

Sorry I didn't read
If you've already full wipe'd your phone and then installed a stock firmware and the issue doesn't solve yet, it may be a hardware-related problem, also because you said that another SIM, working on other phones, doesn't work on your S2.
Try another full wipe and install a different firmware, and if still not, I don't know...

My friend asked me to look at this phone that was softbricked and kept going to CWM recovery everytime it was booted. I updated the CWM to the latest touch version via ODIN then formatted the phone clean. :good: Then I flashed 4.3.1 stable AOKP ROM and the GApps. It was fine, everything else was working. I connected the wi-fi, used bluetooth, signed into google account everything was normal and stable.:highfive: But then I tried calling and it said "no mobile network". Tried sending a text, could not. I went in and searched for network signals then registered to the correct(I AM SURE!) one.:silly: Still no luck. Then I let it choose automatically. Nothing. Then I thought maybe installing another ROM will somehow fix it and flashed CyanogenMod 10.2 stable. Still no luck. I searched around for a flashable radio but could not decide if that would fix it because as far as I am aware if the radio wasn't working no wireless connectivity should've been either.
The phone is Samsung Galaxy S III GTI9300 white 16GB (unlocked) and has been here in Nepal with Nepal Telecom Sim since it was bought. I have no Idea how the soft brick happened but I think this guy tried to manually update the phone with a stock firmware during which some **** must've happened.
Can you guys please let me know if this could be fixed?
Any help would be highly appreciated.:fingers-crossed::fingers-crossed:
There are hundreds of identical threads, search and read about efs and imei issues.

Good day guys.
I have a problem that I think is very common, however I haven't found a solution yet. I recently update my S6 edge (925I - latam) via odin to Nougat, everything was cool but I can't do or receive both calls or sms. I have cellular signal, however there is not registered with the network carrier.
I already flash modem.bin from older firmwares and do not work. Sometimes I loose cellular connection or stay the same, with signal but not registered. I tried other possible solutions like airplane mode and reboot, flashing roms, connect only via 2G or 3G, nothing have worked. My sim is not corrupted and the imei is just fine, without report or related.
I hope you can help me. Thank you very much.

Same issue for me.
Tried:
OTA update
Odin update - installing new stock firmware (with different software version)
Factory reset
Installing TWRP + LinageOS beta
Replacing the sim slot in a service
Nothing worked. Anybody?
Look in settings > status
Do you guys have an IMEI?
This happend to me 2-3 times last 30 days... sometimes I have signal but not registred on network, sometimes there's even no signal, etc...
I also tried several things to resolve the problem...flashing modem, reset dialer, changing network mode, enabling airpalne mode, another SIM card, etc... For the 1st time, flashing modem helped... but 2 days ago when this happened again flashing modem did not help...then I tried changing network mode and I got signal again... last night it also lost signal and today I changed network mode to 4g/3g/2g auto and it got signal again, then switched back to 2g and it's fine till now...
Hope this will not repeat....if does, coulb be very annoying thing...

Bro, download some older firmware from the one you have from sammobile and exctract it...there you'll find modem.bin
At last, I couldn't fix my s6...so I sold it...then the guy who bought it needed to write some chip to motherboard and he got it working again...
