Do you have the correct network settings and correct modem for your network .
Many roms suggest you have not read the stickied basics yet .

Maybe its your carrier that either does not support 3g, or u simply cant get 3g comnection from where u live in cause the company u use doesnt push 3g all the way to your area(happens if you live in a place where not many other people live, or far away from town centres and stuff).
Remember to check the options in the more info(right below bluwtooth and data usage in stock rom) insinde the phone settings

no one from that, i live in city centre and 3g is working fine in (galaxy ace, galaxy s1, galaxy s2, HTC One X)
in SGS2, i flash ics stock rom then put APN then upgrade to JB without factory reset and 3g worked, but now i try this step and nothing happening.

Have u tried some other roms or flashing a fresh stock one? It is known that upgrading the stock roms often causes stupid troubles...
It might also be a problem with your modem...anyhow 3g is not that necessary the way i see it (unless u need it for browsing the web)

i upgraded with odin , i try format system, data & cache then flash rom ,, same issue.
3g is not Important in all country except syria, u need 3g when electricity turn off, and to use it in any palace not in closed place like WI-Fi

R: [Q] 3G doesn't work in jellyBean
Damn...i heard u guys in syria are having a really bad time, this stuff must be frustrating.
Well there may be a couple of options:
1)in syria there have been some problems and 3g is not getting really well to ur area anymore
2)your rom is unstable or just stupid(in this case i suggest flashing a good custom rom)
3)youflashing processes may have lead you to flash a rom meant for a nother regional residence(either the stock one u flashed through odin, or something else u flashed), in this case the "modem" of your phone(it's the kinda way your phone gets cellular data...kinda like an antenna kernel but i have no idea what it is just that it controls your antenna receiving/sending connections) might be wrong. Different modems exist according to where u live (or what operator u use i think as well). Try going on the web and looking for a modem that works in syria and try putting it back onto ur phone(i dont know how, look for it on google).

look bro, i try all solutions before post the thread, i downloaded all rom from sammobile.com but no one worked
can a kernel solve this problem?? or flash another rom like cyanogenmod???

R: [Q] 3G doesn't work in jellyBean
Have you tried a different modem?
To answer your qustions in order:
Not probably and yes.
Try a new rom and a new kernel, it wont hurt....u gotta try to work your way with the phone man, forget stock...even though im not sure how your problem might have been caused....

yes i tried, but no (H↓↑ or 3G↓↑) show in statusbar
i want flash stock rom, but no problem if i flash another kernel ,, do u have any link for a good kernel?? battery life is important for me (u know why :angel:Syria:angel

R: [Q] 3G doesn't work in jellyBean
Good kernel: http://www.gokhanmoral.com/
If u flash i through odin get the tar version, if not and u flash it thru recovery get cwm package. Be sure to get the one for galaxy s3. About battery usage...im not sure...because i have a 2800 battery i got off ebay and it makes my phone last a whole lot longer, if u have battery problems in syria (like the power being shut down for a couple of hourse at times) u should get yourself a battery like this as well, it doesnt cost much.
Plus getting a custom rom is best, i wouldnt cound on kernel fixing your problems too much, give rootbox or jellybam a try. Or cyanogen if u wish but i dont thinks its very stable yet.
Also it is smart to get the latest version of your clockworkmod recovery, to do so download off the store the official app called "rom manager", u can use ut to update the recovery.

and the english is not a problem im italian myself, i dont speak perfect english either
But abkut the rom: if ure sure cyanogen works with 3g try it...
I dont like it either so even though im still on stock ive been doing some research and ive come to the conclusion the best choiche for me would probably be jellybam. A good rom is foxhound(but it is heavy on features) or rootbox(not sure if fully developed yet...).
give jellybam a try just in case.
I dont have many more ideas to help you with your problem as you seem pretty self-conscient of how to flash stuff...i hope someone else can help you, but if i were u i would try flashing some roms and messing around a bit with the connectikn method for data inside rom preferences. U could also try looking in some syrian forums if this is a known problem with galaxy s3 in syria.....

syrian forums? hahaha if any syrian have this issue he won't solve it, and i see xda is the best fourm in the world
the problem is: the phone is not to me, and his owner doesn't like any rom except stock rom

R: [Q] 3G doesn't work in jellyBean
Aaahhhhh the phone isnt yours...damn that makes it even more difficult to fix the problem, even more so if you know it used to work before, but when u changed rom (or put th same one but with odin) it stopped working. That practically means u HAVE to change rom to make it work.....well try flashing stock rom for rooted devices from somewhere else but its gonna be difficult sorting this out if the owner wont cooperate.
I seriously doubt kernel will make some sort of magical changes...

[Q] Bought an used phone and don´t know what root.

Hi guys I am kind of new to this forum and really like all the website with so much information !
I am turning to you because because my friend wanted to buy an SGS 2 and bought one from some random guy whom he has no contact with.
The problem is now that the phone seems to be rooted because there is an yellow triangle that follows in the start up. I wonder if anyone knows how to see what kind of room is installed on the phone? I ask this because because the phone has been unlocked with the simunlock app but
the network connection is so bad, I´ve managed to make 1-2 calls to see that the phone works but i get max 1/5 bars in the connection barometer.
This made me think that maybe the root is bad performed by the guy that did flash the device from the begining.
If you guys have any kind of tweaks or ideas what to do I would really appreciate it.
I gathered some information that might help. This is taken from t he status menu in the galaxy S2.
Would it maybe help to restore everything to stock?

Sorry I choose the wrong section for my thread. Thanks to the MOD that moved it to the right one.
Root has no impact on signal strength.
But if you want to revert to stock, just download original firmware from http://sammobile.com/firmware, unpack and flash via Odin in PDA.

The ROM you use has no effect on your signal strength. The modem however, does. So you can try flashing a new modem if you're fine with the ROM besides the signal problems. ie.the UI, features offered, etc. Else you can flash your stock firmware for your region and that would solve your problem

Go to settings-wireless-mobile networks and in network mode check gsm only...if its on wcdma thats probably why u have poor signal
Sent from my GT-I9100 using xda app-developers app
Thanks a lot for the answers ! I´ve already tried to switch to gsm mode, dosn´t get any better. I will try to flash to a different modem but I have a few questions. Does it matter wich modem is current on my phone before i flash to another?
And if someone could point me in the right direction about wich modem I should use for my region, I live in sweden and use a swedish sim card and operator.
Does it matter wich modem is current on my phone before i flash to another?

No.
For Sweden I think it will be I9100XXLQ6.
If you got the phone from a totally unknown person, i would suggest to revert it back to complete stock, and then start making all the changes you want from scratch, just to be 100% safe.
I agree i´ll flash everything back to stock and start from the begining, I think it´s the best way. But 19100XXLQ6 is the modem that my phone says I have, does that mean that I´am on stock baseband?`Otherwise if someone could show me a link or something for a step to step guide of how to restore everything back to stock.
Thanks a lot for your help guys !
Look backup your efs folder before you start pissi g about with stuff.
Then go to that link and get a 4.0.3 stock firmware for your region.
Then come back here and you can be advised about like siyah kernel/nand backups/roms.

As to my experience, most of the problem arises due to uninstallation not done proplery. Because of this old files do not get erased from the memory and causes conflict.
I would advise you to use rom clean script and do a fresh install oof rom

I'm on a galaxy s1 CDMA so yea its about the same procedure right? You flash it in cwm anyway the only thing that effects data on CDMA if your modem I mean your ROM can affect it but it usually isn't the suspect you need to make sure your own the LATEST modem your friend was probably on a piss poor old modem and that's why he lost 3g there's not scripts to fix it unless its specifically for your device.

Xperia u working really slow

Hi all,
I have an xu and I've been wondering.. am I the only one who suffers from a slow working device?
It was actually working great until the new ics build update (6.1.1.B.1.54). I'm really a newbie so i don't think i shud mess up with my phone but i obviously considered wiping it since i hav many apps installed. I failed to root it (after many tries) with the new version so I have extra apps that i cant even delete, some of them working in the background. And that's why, i believe, my phone isnt working as smooth as before.
It's really giving me a hard time doing simple actions such as phone calls or chatting in whatsapp(i entered the "Apps->running" in Settings and it showed that i have 10mb of free ram) ... many things as basic as these take too much time and its kind of annoying. Is there a way to make my device faster w/o wiping my data? is my problem really caused by the firmware?
I hope u can answer my questions, and when u answer please take into account the fact that i don't know much
thx in advance!
(P.S. i bought my phone about 8 months ago - it's not old or something.)
I doubt you use all of the apps. Uninstall those you don't use.

Please explain a little further .... you tried rooting the b.54 firmware directly using Flashtool ? If so , it's not gonna work ..... you need to flash the stock b.10 kernel first , Root your phone with that kernel , let it boot up,then reflash the stock .54 kernel =) .... give it a try and post the results ...
@ Toon and Bhargva
I really aprreciate ur ideas and ill consider doing them but wiping my data is my last resort. And i think that if i'll flash anything it'll be the 2.3.7 GB and it will (hopefully) be much smoother.
However, I think that the repair thing might rly help so perhaps ill give it a shot and see if it gets better.
Thx again for giving me these ideas I believe they will suffice if there isn't a way to repair my phone without wiping my data.
More ideas are welcome

[Q] HELP!!using international galaxy s2 i9100 screen on sgh i777

hello ,
i bought a factory unlocked galaxy s2 sgh-i777 and i m using it in india but recently i broke it's display/screen and now i got it repaired by samsung india ...they replaced my old screen with the screen of i9100...because of which only theback and the setting capacitive buttons are working and the home button is not working...so can i install official jellybean of i9100 on my sgh-i777 in order to make the home button to work?
i am currently using the button savior app but i m trying to sell the phn anf it would be difficult to sell it because of it's home button nt functioning...
please help...
thanks..
mrinal
Hey Mrinal. Well even I stay in India and I have been using an unlocked SGH-I777. My display has been cracked but ts still working as perfect as it was before.
Well about your issue, I can say is even if you flash a I9000 ROM, you may get the home button to work, but you will have to use the default kernel which comes inside the ROM itself. But as it is meant for the I9i000 you may face certain problems(software related) if you use it on SGH-I777.
So all I can say is if you are okay with the issues that may be faced, go ahead and give it a try.
And please let me know how much did they charge you to replace the display.

hey bro , thanks for answering my question... as per ur ques. about how much money it costs to get it repaired. i gave my phone to a local repairman who inturn got it repaired for me for 7500rs...
btw, u said that i may face some software related problems by using the i9100 rom, but as per i know both the mobiles are quite identical in terms of hardware....
i am quite scared to flash i9100 rom because it could possibly brick my phone and i may have to shell out more money to again get it repaired....
i need to be fully sure then only i will think of flashing i9100 rom...

If you can somehow get root and install cyanogenmod, there is a fix I can think of. Can you do this? I am asking you before I tell you so I don't waste your time.

I have already rooted my phone and also installed Busy box but i'm using original firmware that is UCMD8 which i had flashed through odin. If i can cyanogenmod without modding my kernel then i will possibly is install cyanogenmod. By the way i had already mistakenly bricked my old galaxy SL and damaged its emmc chip, so i'm kinda scared. But if it doesn't involve flashing custom rom or installing modded kernel then i will surely install cyanogenmod.
Mrinal both the phones have different GPU's and there are one or two more differences between both the phones. So the I9i000 kernel will be specially designed to be functional for that specifications. So this may cause you problems. Please just google the "difference between I9100 and SGH-I777" u'll get to know what m talkin bout.
You need to modify the keylayout file, take it from i9100. Hopefully that'll be it. All the rest can be left from i777.
Search for the exact file you need, it's some think like /system/etc/*something*.kl. Google is your friend.
The reason I asked is because there is a mod that gets you nexus software keys, but idk it works with stock rom.

Make sure it is ported to the i777; otherwise yes, you risk bricking it.

No chances of bricking if you flash an I777 kernel after flashing the I9100 ROM. And i dont think you have to use an app for onscreen buttons. I mean if u r on a stock ROM you'll have to else if u r using a custom AOSP ROM then the navigation is already present in the settings..jus have to enable it.

brother, are u sure that with this method i won't brick my phone because one member told me that if i'll flash stock i9100 firmware then i will surely brick my phone...he also said that i should flash a rom that is ported from i9100 to sgh-i777 but a ported rom has been modded to work with sgh-i777 that means it will still have the working capacitive buttons...so i m not able to think what should i do now....
are u 100% sure that by ur method of flashing stock i9100 rom and i777kernel my phone will work..cause i don't think both these firmware and kernel of different phones will work together...

Look. If you are gonna flash a stock I9100 ROM den you sure will brick it. And by stock I mean pure stock straight from Samsung. And if you flash a CUSTOM stock ROM you wont get a brick as far as you have ported it to SGH-I777..to my knowledge. I have done this.
And I would suggest you to flash an AOSP ROM.
And porting the ROM is nothing like "specially mod the rom". You just have to replace a few 'modules' which are in the system/etc/modules folder(M not sure if it is in etc or usr folder) and flash it off. You dont have to change any keylayout file as u want the buttons to work same as on I9100. Please google "How to port an I9100 ROM to SGH-I777". Its pretty simple process.
And make sure you flash a SGH-I777 kernel after u flash the I9100 ROM.
