My i9100 suddenly started showing "No Service" message. What should i do ?
# I'm using P.A.C Rom
# Cleaned cache/delvik and done factory reset. But problem still there
# IMEI is correct but serial number is 'unknown'.
Have you tried restoring a nandroid? I'm also on PAC atm, and haven't had any issues with signal.
Else, try a clean reflash of the ROM.

It worked well before. I don't have any previous backups. Yes i tired re-flash as well. Any other solution ?
Suddenly i noticed network is connected and received a SMS. But when i try to take a call it went back to "No Service".
It could be because of incompatible RIL and baseband. Did you happen to change these recently by any chance?
Don't flash any ril if you're on 4.2. Ril is only ok if you're on stock.
What you can try is to flash the stock ROM for your country /carrier. See if the problem persists .
And just a word of advice, always have a backup ready to go.

Flashed official firmware with Odin. But problem still exists. I noticed strange thing. One of my SIM cards working on it. But 2G network. Sometimes shifts to 3G but can't hold also signal strength is low. When i put other SIM it says Not registered on network (cant manually register even)
Did you definitely flash the firmware released for your carrier & region? Sounds to me like you may have flashed firmware intended for another carrier or region.
Try flashing a few modems. Look at which modems your carrier released for your region, start with those. Then, move onto o re her local carriers etc. If you still don't have any luck, go all our and flash whatever modem you can get your hands on (make sure it's compatible first obviously).
It may sound like a lot of work, but unfortunately there's no quick fix for something like this if flashing stock didn't work.
Oh wait. If you did actually flash a different stock rom, flash the correct one first. If you did get the right one first off, start flashing modems.

Ya. I flashed correct firmware. I'll try some more custom ROMS as well. With this ROM i can get 3G and 2G networks. Data also working. But signal is low. You think its a modem issue ?
Hey there,
I have a factory unlocked Samsung Galaxy SIII, international, GT-I9300, freshly rooted and using CWM-based recovery v5.5.0.4::CF - v1.5.
Today I've flashed 2 custom ROMs, one after the other, by following some guides that I've found (cannot post yet links):
1. Android 4.3 via SuperNexus: URL hidden
and after the SuperNexus this one:
2. Android 4.3 via ParanoidAndroid 3.97 ROM: URL hidden
Managed to flash these two successfully, but with both of them I've faced the same problem during initial device setup: could not connect to my Wi-Fi network. Wi-Fi signal was strange too: strong, then suddenly weak. Could not authenticate and connect. :crying:
So, fortunately, made a backup before these two ROM flashes, so I guess I'm back with my stock Samsung TouchWizzy ROM (Android 4.1.2). That I hate. I want something bloatware free, stock-android feel, something like my Nexus 7 tablet.
Can you suggest me a "Wi-Fi capable" stock-like Android 4.3 custom ROM or am I missing something? Maybe a Radio flash (have no idea what's that) but maybe that what I was missing? And if I do that somehow, is that reversible? Never done it before.
Thank you in advance for any help and suggestion! :good:
love,

(1) did you do a full wipe including manual wipes of /system? If not do so and try again (mega wipe can be of help here)
(2) if this doesn't work, did you play around with custom kernels? (wifi is connected to the kernel and less to the baseband/modem used)
I am running SlimBean 4.3 (beta5) without any WiFi issues, also all other roms before that, no issue.
This must be a modem issue as android 4.3 does not change the modem from the previous samsung rom.
try upgrading to latest samsung 4.1.2 and then install android 4.3.
install 4.3 after doing a mega wipe.
remember to backup everything.
and dont forget to take an efs backup as many ppl are facing major problems after upgrading to latest samsung roms.
Guys, Thank you all, trying to reply to everyone:

1. Thanks, will do a mega-wipe next time, although with CWM did these in the following order: Wipe data/Factory reset, Wipe Cache Partition, Wipe Dalvik Cache several times. Also, with MegaWipe wiping Preload partitions does what exactly? Just don't want to brick my phone/do something irreversible, as I try to understand everything I do to it
2. No, did not played around with custom kernels. Do not know how to change/flash them. Same as flashing a custom rom? Newbie here :laugh:

(1) The best would be to read the mega wipe thread. I use it all the time, it will delete ANYTHING excep the external SD card (also not EFS etc, hence dont worry). Therefore you need a flashable rom on the external sd or via Odin later on. But basically your phone won't start after a mega wipe, just download & recovery will work.
Your wipes are correct I think, whereas /system is missing wich is needed, at least for SlimBean (4.3).
(2) The best would be to read the guides & kernel thread's how-to's first. It is basically the same as flashing a rom, yes.

Well if u r a newbie. Read all the guides available here. Dont proceed further without doing that. You will learn how to backup efs and all.
U can install any latest custom samsung rom. Again.. Read the guides/warnings before proceeding.
Misleading title .
#There have been a number of identical posts and some have fixed by copying older WiFi files over . But you need to search and read and no i don't know where they are . .
Its not a custom rom problem but a non Samsung custom rom problem on 4.3 .

Yes, reading the guides, so first of all decided to backup my EFS (coz that sounds reassuring before doing more ROM flashes) with EFS Professional from this thread: http://forum.xda-developers.com/showthread.php?t=1308546
Installed BusyBox on my phone, and I'm stuck because of a missing applet: http://cl.ly/image/1a1J1A0I3V0H.
I think I'm going deeper than what I can handle
BTW, Enea307, tried CM 10.2 (4.3) this morming, and same wi-fi problem. So it's most likely not a custom rom issue, as most of you suggested.
The only logical; way to rule out firmware is by wiping the phone and flashing stock rom .

Not installed KIES yet, as I read that that's a big brother or something to Odin, and that his little brother is much better at flashing. Should I give KIES a go? Anyways, trying to redownload the firmware.

Some roms, mostly PA (paranoid android) just happen to have wifi probs.
I used to have pacman rom earlier and as it was a combination of cyanogen mod, paranoid android, and AOSP roms. It had a part of all three in it, so the wifi bug persisted. Went back to stock rom later.
Usually stock roms are the best and most stable for your phone, No matter how much the hype is, features are, or however big Nd bold letters STABLE is written in. Just delete the bloatware given by samsung to get ur phone clean and ram light. You can delete system apps by using titanium backup.

Thing is, that I am rooted, done with Odin, by following this guide: http://www.androidrooting.com/how-to-root-samsung-galaxy-s3-gt-i9300-or-gt-i9300t-cwm-recovery/
So I have CWM, and with I tried Android 4.3 via SuperNexus, Android 4.3 via ParanoidAndroid 3.97 ROM, then, lastly CM 10.2 (4.3). With none of them did I managed to get the Wifi going.
Here is my current "About device": https://www.dropbox.com/sc/8hp04dn5o5flytd/LpoJCgZ7sK
Is this stock samsung firmware? Coz I can't tell. It seems stock, but maybe it changed with the rooting procedure.
So I repeat, only with this setup/build does the wifi work. With no other custom rom does...
I did backup and recovery to my current working wifi rom. That's how I recovered after trying these custom roms mentioned before.
Guys, help me pls, with at least flashing to the stock samsung rom with Odin or Kies (Odin failed, scroll up see my recent posts with screenshots)
Note that on my last try, Odin just froze yet again: http://cl.ly/image/0o0o0k2L3J3m
If not with Odin, then how do I restore it to stock samsung rom with KIES?
thx!
You dont do it with kies. Kies is such bull**** software. Dont use it at all. You wanna backup, use TI(titanium backup) or nandroid backup. Take a system backup from CWM. As you said in your post, u want to go back to stock, dl the stock rom, do the same procedure u did to root your phone via odin (pda, etc etc), just this time instead of the root zip file, just put the stock rom zip file.
It should take some time, and aftet its done, your phone will be as good as new. To restore the backup via TI, dont select system apps. Only the apps which are in green font or downloaded apps. Other wise u will have force closes.
Also, when u flash the stock rom via odin from your pc, you will not have root. Just a note.
You can simply remove bloatware like live wallpapers, samsung "never gonna use" features like Svoice via TI by just uninstalling them, but note, if fiddling with system apps, them make sure u take a backup.
I have written it all in simple language so that you understand every essential part and have fun with your rooted phone.
Happy to help
As always last resort restore original firmware with Kies and probably a better method than some others posted.

Hello everyone,
First of all i want to thank you for all this guides that i was trying to use here
So here's my story.
I got Samsung Galaxy S3 I9300 with bootloop issue so i decide to fix this by myself.
I was trying to install fimware using KIES but i doesn't fix my issue.
Then i was trying to search for right rom on several websites.
The right one and only working one was 4.0.4 with orange brand logo.
So i was excited that its finally working
Then i realize that my imei is null and my sim card is not working.
So i was trying to restore EFS using several tools and methods.
Finally i got it default IMEI 0049 but it was still not working.
My phone is not qualcomm based model so i cannot use nv item reader writer as it's required to edit IMEI
Even after applying phonutil patch my device is not being recognize as Qualcomm one.(because it's not)
So i was still looking for another way to change my imei manually as i have my original one on the box and under battery.
Finally I realized that i cannot make even Emergency calls it comes with message Out of service area.
So i was trying to apply few modem and radio updates to my phone but none of them are helping.
Anyone have similiar issue?
I have another Galaxy S3 that is working can i copy imei or whole system to my not working phone?
I know that after that i cannot use other device, but thats ok if its possible.

Regarding patch:
4.0.4-I9300BVALE4 firmware is the only one working on my Samsung
Patched modem and kernel that i found and try it are XXUGMK6.
Maybe they are different one or dedicated to my firmware

The reason you can't make calls is because at some point your phone software was on 4.3 this means your efs as changed to efs v2. Now because your current firmware is at 4.0.4 then your efs can't read this because 4.0.4 is efs v1. So you need to get a 4.3 stock rom onto your phone (I know you said only 4.0.4 works) but what are you using install firmware are you using Odin? If so what errors are you getting installing with Odin.
The patched modems and kernels are for 4.3 so they won't work on 4.0.4 or any other apart from 4.3
I was trying so many of them but its always ends with samsung logo loop it doesn' matter if i'm
do things like wipe cache, factory settings etc everytime its not working.
Even on 4.0.4 only this one rom is working.
Im always using ODIN, with KIES its always ends with samsung logo loop.

Ok a couple of things you could try (if you haven't already) I presume you have a custom recovery? Try flashing a custom stock 4.3 with recovery I suggest this >> http://forum.xda-developers.com/galaxy-s3/general/rom-sammys-stock-deodexed-rooted-t2585670 << This is as close to stock as possible but can be flashed with a custom recovery like Cwm,PhilZ,Twrp etc. You will also need to flash a 4.3 modem for this which is included in the thread. If the modem in the thread does not give you a signal (presuming the rom boots ) then keep the same custom rom but flash a patched modem and kernel on top with your custom recovery.
Don't forget to factory reset after flashing!
If none of that works you can always try the rescue firmware here >> http://forum.xda-developers.com/showpost.php?p=30087735&postcount=6 << obviously flash the 4.3 one. Hope that helps
Thank you very much for your help i will try this and let know here if it's working

So it's me again.
I have good news and bad news.
So i was able to install both of firmware with success.
After applying patched modem everything was still working.
But when im calling 112 for example im still having "out of service area" and my imei is still 004999...
So issue is still exist.
I can discover any network when i choose network its even says"registred on network" but then if im trying to choose some number im having error message that im not registred or if emergency call "out of service area".
Any ideas what still can i try ?
hey guys!
I have samsung galaxy s2 gt-I9100. Whenever I install a custom rom, everythings works fine but i am not able to use mobile network and i received "Error while searching for networks" when I go to settings>>Mobile networks>>network operators. The IMIE number is fine.
I have tried many roms including:
--cm-10.1.3-i9100
--cm-11-20140804-SNAPSHOT-M9-i9100
--pa_i9100-4.42-20140708
--pa_i9100-4.45-20140729
--Slim-i9100-4.4.4.build.9.0-OFFICIAL-8301
The last rom which worked fine was RootBox-JB-i9100-V4.0. All roms released after this rom have this issue.
I have searched for issue on google and tried various solutions but so far no success.
Please Help!
And can you guys suggest me any rom which is not based on CM?
Go to settings-->about phone and look for "Baseband version"
If it says "unknown" or similar you may need to reflash the modem before you flash the rom.
Or even worse you might need to do a reboot (it actually worked once).
Also do emergency calls work? If yes then it might be a problem with your sim card or you contract (or just bad luck).

The Baseband version is visible and a valid one. Also my sim works on stock rom or any other phone.
SInce I have no idea what the cause could be, here are some random things to try out, of which one might work:
-make sure you're not in airplane mode
-do a full complete wipe
-try a different sim (and see if it works)
-make sure the sim is not upside down
-fully shutdown the phone (e.g remove battery for a day [maybe not that long])
-clean contacts between sim and phone (how? no idea)
-try (even-) more roms (if there are any left)
-test a few kernels
-maybe look through the logcat (if it actaully outputs something worthwhile)
As you can see none of these "soloutions" are based on.....uhmm....anything(?). But at least....if none of them work, you know what not to do.

Perhaps you could flash back to stock rom then flash custom rom again, that way all modem files and network related files can be fixed/re-installed. By any chance have you tried changing modems? It might not help you but it's a suggestion.
