Hi everyone !
So i have this i9300 rooted on custom rom revolutionary (and i wonder if that itself is the problem) and 3G just won't work. I don't get the "H" nor "E" nor "3G" icon when enabling data, it's just frustrating. I have tried all tips i found on the net : resetting apn, turning airplane mode on and off, taking off battery etc ... i even put dad's card with which he uses 3G without problems, configured apn and enabled data and roaming, but nothing, not even a sign of 3G. How can i make it work ? I can give whatever infos you ask but please give instructions as i'm a noob :laugh:
any help would be welcome ! thank youuu

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.
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.ΓΌ
Hi there!
I know I'm new to here, but not new to android, flashing, etc...
So I recently bought a Galaxy S3 international version (GT-I9300).
I tried to update it's software with KIES, and it stopped on 61%.
KIES tried to flash the newest 4.0.4 (UK) firmware (I9300XXBLG8).
I got the .tar.md5 file out of temporary directory and flashed it manually from ODIN. It booted normally, but i had (have) no network signal. When I turned it on it requested my PIN but when I entered it, the phone doesn't connected to my carrieer's network. My phone is unlocked (checked it with galaxsim), and my IMEI number doesn't changed or corrupted. (Checked under the battery). I live in Hungary and my carrieer is T-Mobile. Tried hard reset, wipe.
Can anybody please help me to solve this problem?
Thank you very much in advance.
Tom
Hi Tom ,
it happened that I had a bit of a similar problem before ( not with my Current International S3 but with my older Xperia neo v ) , after flashing a new ROM something went wrong and I had lost network , tried everything possible but it wouldn't do anything.
my solution was flashing back to my previous ROM , so I highly recommend to you to flash back using your NANDROID backup ( I hope you made one before Flashing... ) or you can try another ROM / or even RE-flash your current ROM but pay more attention this time and make sure nothing goes wrong , and also make sure you do a factory reset , Cache wipe and Dalvik cache Wipe before you flash it just to make sure everything is clean.
I hope this helps , and if I helped you by any way possible don't hesitate and press the Thanks button on your LEFT :good:
Cheers

OT I don't have thanks buttons, maybe you should qualify with an IF statement?
Bad news, I don't really know what my original firmware was, so I can just try Kangburra's tip... I have 25 min waiting time on hotfile.com, I will the download the latest 4.1.1 unbranded firmware, which has PDA I9300XXDLIH and CSC I9300PHEDLI1. I will write about the results ASAP.
edit: I'm too tired, I thoght your signature was a suggestion for me

It seems you misunderstood me... I have absolutely no network signal from my carrier :/
Update: Okay the last 4.1.1 mentioned before is not working. Now it sees my network just doesn't register on it. Will try I9300XXALE8_I9300OXFALE5_XEH now.
Found something: All of ROMs installed I'm seem to be reachable. My friend ringed me from his mobile and IT WAS RINGING. If I turned off my mobile, it was not ringing of course. So what the hell is this?
Hay everyone .
I recently flashed salmanrom v 4.2 and everything went fine until I was unable to use network data my carrier gives me. However, I could still connect to wifi.
I can still send messages and calls but I can't connect to the internet because I'm unable to to use my network data. I tested the the sim on another phone and everything worked perfectly even the network data.
I'm really frustrated someone help me please
Known issue with that ROM?
If not, flash a new modem.
If you are getting your network you should be able to use data tho.

Check and make sure your APNs are set properly for your carrier on the phone you do not get mobile data on.

Maybe could help a full wipe and re-flash the same rom...

That is excessive if fixing APNs might solve his problem. Plus, re-flashing the same ROM may not auto populate his APNs anyways.
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...
