Hey guys, I need help reviving my I9100. I had it rooted and running CM for over a year, always upgrading to the latest nightlies when out of a sudden it started to lose network connection. Now it doesn't get any connection at all, no matter what I do....
Here are a few things I have done (not necessarily in that order):
- searched the forums for similar posts - didn't find one that matches my exact problem
- restaured a few different backups from when everything was working with CWM
- flashed older versions of CM (all the way back to CM7) with CWM
- flashed the original factory ROM with Odin
- flashed a few different modems with CWM
- factory reset, data wipe, cache wipe, fix permissions, etc. with CWM
- used GetRIL to fix RIL (tried a few different ones with each different modem flashed)
- tried my SIM card in other phones and it works
- tried other working SIM cards in my phone and it doesn't work
Not sure what else I can try before assuming it's a hardware error....
Everything else works fine - WiFi, Bluetooth.... basically my phone is now an iPod lol...
TIA
If your SIM works in other phones than the SIM is not the problem.
If your phone doesn't work with other SIMs - that's you clue right there. Is your phone locked to a specific carrier? If so, try other SIMs from same carrier. If the phone is factory-unlocked and doesn't accept other SIMs - it's a hardware issue.
Edit: Please check if *#06# shows your iemi.

My phone is carrier locked but the other SIM I tried was from the same carrier, so it should have worked. I have the unlock code anyways, just never had the need to unlock it. If anyone thinks it might help with the diagnosis I can find another carrier's SIM to unlock the phone and try it out.

Yes it does.
If your SIM worked in other phones from same carrier, but no SIM works in your device, I sense a hardware fault.
Don't rush unlocking it if you plan to have your carrier to repair the phone. It might disable your warrenty or flag your device as "tampered with".
Again, if no SIM seems to work in the device and the iemi is NOT blacklisted (for some reason), it's a hardware fault.

My phone is not under warranty, which is the reason why I really need to try everything possible to fix it. Otherwise I'll have to buy a new one out of my own pocket...
Is there any chance a bad Modem and/or RIL combination might be the problem here? Would flashing through CWM instead of ADB (which I haven't tried yet) make a difference?
Alright, this is what I should do:
- Sim unlock your phone.
- Make sure you do a full wipe.
- Flash a stock rom.
If you still have no reception, then its probably a hardware fault.
Now you could do 2 things from here on. Either you use your phone for listening to music or you open up your phone. Inside your phone there is a white cable. This is your atenna cable, take it off and connect it again. Test your phone now with your simcard. If it still doesnt work, try reversing the cable. Try again if it doesnt work. Try this procedure a few times.
If it works you are lucky, if it doesnt work you have a serious problem.
Opening up your phone is really easy, just search Youtube for instructions.
Hardware issue? Easy now....no need to rush things out.
@OP where did you get the unlock code? From your carrier itself or third party?
You've tried a lot of modems, are you sure you don't wanna try 3 or 4 more?
When you look for a network, does it even see the available ones?

Sure! which ones do you suggest? And how should I do it right? I've always just flashed them with CWM and never had any problems. Initially I only flashed the files codeworkx made available to flash with CM, but once I got this problem and couldn't fix it I flashed a few different ones from here. Does it make a difference if I flash them with ADB instead? I haven't tried that...
gastonw said:

No, doesn't find anything. It even feels like it is not even searching at all. I remember a few times before it would take forever to find all the networks (did it a few times when travelling)... but now it says "searching" for a few seconds and nothing - back to the "available networks" screen without giving me any results.
Sure sounds like a modem thing.
There's a thread filled with modems in the original android section, you could look there.
You've never been to jb leak's land?
It's a good international modem, might work. It's LS6 I think. Feel free to try the whole ROM, can't hurt right?
You can also flash them with odin.
Sent from the little guy
OK, here is something I don't get:
Downloaded the LS6 modem, flashed with CWM, wiped cache/dalvik, reboot. Still no signal. Then, just for curiosity, I opened GetRIL. It showed me a RIL mismatch:
RIL: XXLQ6
Baseband: XXLS6
So I click to download and install the correct RIL (couldn't hurt right?). After download/install I reboot, wipe cache/dalvik, reboot, and still no signal. But now, when I go to to System Settings >> About Phone my Baseband Version is "unknown".... not even GetRIL recognizes it anymore.
Flashed CM nightly again to get things back. Now I have my baseband back (XXLS6) but still no signal.
@gastonw -> I don't pay much attention to leaks since I have been using CM Nightlies. But I'm downloading the I9100XWLSD ROM from the Official Firmwares thread to flash with Odin... let's see what happens...
Edit: Instead of matching the RIL to the baseband I tried the opposite - flashed the XXLQ6 modem. Now GetRIL shows me a perfect match.... and still no signal.
Try stock to see if things fall back to place.
Once it's fixed you can cyanogen mod tha phuck outta the device
Now, I've suggested JB leak (lsj) because of the "International" tag, you are now downloading nordic, so that could cause trouble (I'm in Uruguay and it works just fine tho).

Since 2 days i can't phone with my S3.
When i call someone, my s3 sounds nothing and i can't hear someone and someone can't hear me. If someone is calling me, there is the same problem.
Please provide more details of you firmware so others may try of understand the nature and cause of your problem. Knowing the cause will most like lead to the solution
ie. Any changes made since the problem
1. Rooted?
2. Firmware version including baseband
3. Custom or stock?
4. Any mods, flashing, setting changes since working?
5. Apps installed since?
6. Have you Factory reset?
7. Any other info that would be useful sincethe problem started..........
1. Rooted?
2. Firmware version including baseband
3. Custom or stock?
4. Any mods, flashing, setting changes since working?
5. Apps installed since?
6. Have you Factory reset?
7. Any other info that would be useful sincethe problem started..........
1. NO ROOTING
2. FLASHED TO ORIGINAL Firmware with no Apps or Games. I installed nothing and with Factory Reset.
AP: I9300XXALE8
CP: I9300XXLE8
DBT: I9300DBTALE5
Before the problem started it was rooted.
but i can do and try what i want.
my simcard works with other phones.
my galaxy s1 has no problem.
only my s3 has a problem with calling.
i can't hear someone and someone can't hear me.
when i will call someone there is no dial-tone.
1. Try switching and test between GSM and WCDMA
2. Flash back to your origninal firmware or try another firmware or modem
[Guide+ROMS]Odin Flash+Root Guide & Stock Firmwares LE4/6/8/9/F/D, LF1/2
++ Do you still have original IMEI number?
Try switching and test between GSM and WCDMA
I have tried it, but there is no reaction.
yes i have original imei.
If you have exhausted all the previous suggestions, can't imagine it being any fault of the firmware. More likely hardware.
I'd erase all evidence of rooting and make sure sure you flash counter in Download mode is Zero and Settings > Status > Device Status does not read modified >> return for warranty repair or replacement
Sorry, can't think of anything else yet
yes i think its a hardware error.
all other functions internet, etc are working correctly.
I'm having the same problem.
i also had a problem with calling. i think antenna is faulty since the phone loses signal. just replace it.
I also have the same problem. I want to find a new modem firmware. but cant find it anywhere.

Why bother with repairing anything when that will void warranty. Exchange for new if possible, or official Samsung service centre.

i had the same. you can try to reset your phone via settings
I doubt that this a hardware error.
Reason 1: speaker and microphone are working.
Reason 2: mobile data sending and receiving is working.
(if this is an error with the antenna i think i can't receive and send mobile data)
Reason 3: i have always a good signal.
i have only a problem with calling. and this with 3 other tested simcards.
after the ending of a call it comes for 2-5 seconds the message that i have currently no signal.
Hi there...
I'm having a problem with my S2, so here's my questions in case you can guide and help me.
I'm went on a trip to Germany and I took my S2 with me. I had the phone on Airplane Mode 99% of the time. I turned off Airplane Mode once or twice, and the phone got Reception (signal), but immediately I turned Airplane Mode on again. I didn't need calling or messaging. Then I bought a prepaid chip from T-Mobile, turned off cell phone, installed the chip, turned on phone but phone didn't "recognize the sim".
So, I turned it off again, insert my original sim (the one I use in Costa Rica), turned on the phone, but again, the phone didn't "recognize the sim". I tried those 2 Sims on another phone in the "T-Mobile Store" and both sims worked perfectly. My S2 also showed a "blank IMEI" fater dialing *#06#.
Now I'm in Costa Rica, and the phone still "don't recognize my SIM" and the "blank IMEI" still shows.
Someone knows what can I do? Im completely lost. I found this tool and this guide. Do yo think I can solve this problem with any of those? Or, what do you recommend me?
My phone is completely stock, no root, no custom roms or anything like that. And it's not on guarantee. I'm pretty much a noob, hope you can help me or guide me...
Thanks a lot in advance!
It seems like your baseband has lost, you can check your baseband in settings-about phone, if the baseband is unknown try to reflash another modem,if you are a newbie, ask for experienced one to help.
The links you provide are not recommended for newbie, and efs backup is no use for this situation that you have no any backups, you can try reflash baseband, that's safer.

Thanks for your answer. You are right, my Baseband is Unknown. So, in order to reflash the baseband I need to reflash the Modem? Will you recommend me to reflash the original Modem or another one?

No, I don't have a Custom Rom... I don't know how or why the Baseband changed to Unknown. Ok,I'll try with the original modem. The only way I know how to flash things it's using CWM... it's that ok or should I do it with a different method?
And another question, someone told me that with a Hard Reset, the problem should be solved... do you agree or disagree?

There is no harm in trying hard reset, backup whatever you can and try hard reset. If it fails :
for CWM you need to root your device and install CF root kernel first. You should try flashing baseband through Odin. You can find the baseband/modem files and tutorial here
http://forum.xda-developers.com/showthread.php?t=1075278
Its far easier than going through CWM, install samsung drivers on pc and you are ready to flash. Do read carefully every step. Good luck.
Ok, thanks a lot. I appreciate your help. I'll try all the above and let you know how it goes.
Hey guys, I'm in desperate need of some assistance here.
I have an international Galaxy S3 i9300, rooted and with CWM.
I flashed Criskelos XXDLH8 ROM yesterday, and I followed the instructions to the dot.
The flash seemed to be problem free.
However, once the phone booted and i was on the new ROM, i tried to make a call, but I kept getting an error message saying "not registered on network".
I instantly freaked out, and wiped my phone+cache, and flashed stock Samsung ICS (XAALE8) via Odin.
The phone booted normally into the stock ICS. But instead of seeing signal bars on the status bar, all I can see now is just a circle with a line through it . :crying:
I did some research on the net, and didn't really find anything to help me, which is why I'm here, seeking ANY help from you guys.
I'm freaked out guys! Any assistance would be SO appreciated! thank you!
don't panic
go settings >wireless and networks more settings > access point names
make sure you have something in there

look up apn for your area.
otherwise you can try flashing a different modem for your region or even try another region from here

Are you sure the firmware is suitable for your model for your phone's factory? There are at least three regions of producing Galaxy S3 International version. Some final product made in Vietnam and Korea has a lot of problems and need to be changed to the board made in China due to software problem. You should try using the "Firmware Upgrade And Initialization" in the "Tools" in the Samsung KIES 2.5 because it will download the latest official firmware according to your model and serial number and it will wipe your phone at the same time.

It sounds very much like a locked phone that was unlocked in a suboptimal way
Unless you have the original EFS (on which you might try to do a cleaner unlock) you will be "condemned" to always need a patched modem.
The short story is that network locking is done in a protected/checksumed database in the EFS partition and some older unlocks were not even attempting to keep the database "clean" - they were forcing a flag there but since there was some other check at a later time you need a special "patch" in the GSM modem code - that is located in a different partition and might be a little different from one country/carrier to another. Unfortunately the modem is (usually) updated with major ROM updates, so you have now lost that patch - but you can take a look below for a fix:
http://forum.xda-developers.com/showthread.php?t=1918601
The bottom line is that (unless you restore original EFS and do a very clean unlock) you will always have to re-apply the modem after you program a new full ROM!
I just repair my i9100 which had the emmc bug with a used emmc chip.
I manage to backup b4 it hardbrick.
Will restoring my old nandroid write my /efs???

When i type *#197328640# to read imei it show Imei : Not Supported
No, restoring a nandroid backup will not touch/restore/overwrite your EFS, unless your EFS isn't borked in the first place & it's only 'temporarily' disappeared, and even then it's more likely simply rebooting rather than restoring the backup fixed the problem.
Edit - That problem you're describing is either a simple connectivity issue (which could be carrier side or could be solved by trying different modems), or perhaps something was damaged when the phone was repaired. If it was an IMEI issue, you'd have no connectivity full stop.

Try to flash few modems n 2 custom rom but still the same..
I check the coaxial cable n is fine...
Replace the charging port and speaker(antenna) but still the same...
Tried other sim/carrier but still the same...
The most confused part is why it only happen in buildings?
Put it this way, you opened the phone up & replaced stuff. You sometimes have connectivity & sometimes don't. If it were an EFS/IMEI problem, you'd notice you have no IMEI & you'd have no connectivity all of the time. So thinking logically, the finger points & something not right with hardware. As to why it's happening in buildings, that sounds like an issue of the radio not operating the way it should.
Having said that, there are dozens of modems, you've only tried a few. Before you start investigating the hardware side again, if you haven't done a clean install of stock recently, do one. Then look for modems bundled with stock roms released by your carrier. Try those. Then try modems bundles with stock roms released by other carriers in your country. Try those. Then if you're still not having any luck, try every modem from every carrier/country you can get your hands on.
If you've done that & you're still having the issue, it's either something carrier-side or a hardware issue.
Um...restoring a 4.0.4 nandroid.....probably best NOT to do that....even as a last resort......
And check under settings...about device...status to find your imei number....if it's there (even when you have no connectivity), then it points to a hardware or modem issue.....

Indian ROMs tend to be sneaky when it comes to modem.

What you mean they "failed"?
You can't flash them or you don't get any signal?

If you've tried everything else, I suggest you take it to Service Centre near you. Looks like that fall is to be blamed.
P.S. Please post device related issues in their specific forums. That way you will get faster and better answers! :good:

Thanks for quick reply and sorry for the wrong post,i will take it to service center though i live in island where there is no good service center i need to travel by sea to get to good service center by nextweek thanks once again Regard:good:
I think you've lost your IMEI! here is a guide for recovering it. If you didn't root your phone to void your warranty, it's better to take it to a service center then.

im out of warranty and i took it to service center but they tried without success Due to baseband and imei unknown problem,the guy told me that it is software he flashed it several times but it didn't work,so i have to take it back,i will try the link and give u feed back,thanks for your help
i tried that link but unfortunately it didnt work may be is because i didnt have backup of esf files i missed some of the files like .nv_data i only have nv_data.bak,
So, your SIM card lost contact when the phone hit the floor and then instead of trying to remove the SIM card and put it back in you went and flashed the phone to solve the problem and that resulted in loosing IMEI number?
The Custom Rom you installed didn't make backup of your EFS folder?

yes exactly when the phone hit the floor and then instead of trying to remove the SIM card and put it back in i went and flashed the phone to solve the problem and that resulted in loosing IMEI number, but before i flashed it i made a backup of my rom using twrp but after this crash i restore my rom using the same twrp but my phone hang on booting,i was using ApoloJb_4.8_Extremev2_twrp kernel
the phone is acting very strength now,i found out even when i installed stock rom, my files are still on the phone,i used odin flashed it,please can any one provide link for me on how to fresh install stock rom and clear everything on the phone
How to install stock rom ? Search. This has been covered here thousands of times over the past two years, I'm not about to regurgitate it because you can't be bothered searching. Get a stock rom for your carrier/country from Samfirmware, then read the guides/tutorials stickied near the top of the General section.
If you want this fixed it's going to take a bit off effort on your part, we can't do everything for you.
Have you
1) Try another SIM card?
2) Look at the mobile network setting? Look for any abnormal setting? can search the mobile provider etc?
3) Try to flash another modem driver?

Hi, to add on, maybe you should tried again flashing with different modem/radio. The different ROM that you flashed may be using the same modem/radio and they may not work on your phone.
http://forum.xda-developers.com/showthread.php?t=1131950
This link seems to have mentioned various modem/radio for S2. You may want to try it. You may want to refer to another working S2 and check out what is the working modem/radio working well in your area. Then you flash in the same radio/modem.
If this still does work, it may be really the dropping of your phone has kill some physical part of your phone?

still don't work? strange!
just now i experienced the similar issue like yours, no signal bar. this happen after my phone become no respond to any key press. i have to hard power up through long press. when it power up i then see that there is no signal.
so i quickly go to recovery and flash a Modem/radio that i downloaded earlier.
after flash and it booted with good signal.
but my cause of issue i believe is kernel related as i just flash a dorimanx kernel yesterday.
