Signal problem with I9100XWLS8 (4.1.2) - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
i'm from argentina and i'm having a signal problem with the I9100XWLS8 (4.1.2) rom. previously i was using the 4.1.2.(XLSJ). and when i changed from one to the other, my signal was blocked.
i tried by restoring the EFS folder with the KT tool program.
also i tried to unlock the phone with the Galaxy Sim unlock program.
but nothing seems to work...
any help??
thanks!

Did you try using the modem from LSJ on this rom?

i've just tried, by putting the LSJ modem on the "PHONE" of odin..
and nothing.. problem still occurs.

is it to hard to make a clean install? make a backup and do a full wipe (internal sdcard not necesary)

doesn't work either..

if your imei number is correct in android os, maybe your phone has been reported stolen or lost, changing rom got nothing to do with your signal lost.

Polish I9100 with LPS loosing network

I have the polish unbrended I9100 with the official LPS update, but I am loosing network all the time and lots of calls go straight to my voice mail. I did try to go back to LPQ, but could not find an officiel one. When I loaded one with the LPR modem I had CSC unknowen and again loosing network all the time. I try to change with the band selection but no luck. I am on Rogers in Canada. Any help will be appreciated.

I've got a similar problem with LPS and LP4. The funny thing is that antenna idicator shows full signal strenght.
Full wipe did not helped.
So you know where I can get an official LPQ? It was OK with it.

Same problem here, and I have flash back to LP3 modem. Just extract the modem.bin from LP3 and flash via Odin to phone
Sorry for the stupid question, but how do you do the extraction! Thanks a lot!

It looks like I have two modems now. Is this the case? I will see tomorrow if the receptions is OK and if I will be loosing the network.

if you have the .tar.md5 file, just open it with any zip program like winzip/7zip, then extract the modem.bin.
Sill the sema problem. Now I will try to change the whole rom to LPQ. I really hope it will help.
Now I am on a full LPQ and I still have the network problem. I lose conection to the network and in 10-15 secpnda I get all bars. The problem started when I got the official LPS from the forum. Is it possible the Odin flash to have done fisical domage to the phone? I got it from Expansys USA, but I doubt it they will do something. Any help will be appreciated

I tried only GSM bands and there is no problem, but the moment I add any of the WCDMA bands I start losing the network.
Maybe try full wipe before and after update (usb masstorage, dalvik cache and system) and flash LPQ again.
Or go back to 2.3.x

I did a full wipe, but now I do not have CMW, because I thought it had to do something with the rooting. Is there a way to test if the radio is fiscally damaged? thank you very much for the respnse!!!

I don't know if its possible to check it.
But can't you just flash some GB ROM using Odin? If its still doesn't work correctly with GB ROM than it must be something wrong with the phone.

I rooted the phone, did a factory reset, wipe cache, wipe dalvik, after install a new rom wiht Odin, factory reset and still the same. I bought it with Expansys USA, and they told me it will take 6-8 weeks to have it sent for warranty repair. I guess I will try with a GB rom and see. Thank you.

So far no luck. The last thing I put was the Luxembourg file, but it has the same modem LPS. I was trying to have a different CSC and see if this will help, but it did not.
Now I am giving a last try with UK O2 file, and if no difference I am sending it back to Expansys US for repair. I hope they do not come back and tell me that there is no problem with the phone.
dont want tobe rude but it seems you are not listening to what ppl saying......
before you snd your phone atleast check with Gb ROM.
if i were you i would full wipe the phone including system partition and flashed stock GB ROM using odin. and tested it without doing any thing more.
you want to fix your phone you better start forgeting your stuff and try what has been said here.

Network Not Registered on Stock or other ROMs besides Android Revolution HD

Good day.
I was going back & forth from Stock & SuperNexus 2.0 just fine. Then I tried Android Revolution ROM, and now my problem is everytime I flash Stock or any other ROM, I can't text or call. The signal bar is fine. It's just that I can only make Emergency calls and it says Network Not Registered. But if I flash back Android Revolution, it's fine again. I've tried the clean routine (Factory Reset/Wipe Cash/Wipe Dalvik), still no luck.
Anyone encountered this before or any solution/suggestions?
Thank you.

is your imei intact? does it match what is under your battery? how about serial number? did you flash a rom with an mg4 or mg2 baseband? do you have a backup of your efs folder? read these before flashing anything further http://forum.xda-developers.com/showthread.php?t=2393289 http://forum.xda-developers.com/showthread.php?t=2377731
good luck!
Thank you for the reply. Im guessing that's what happened. But I will try to determine if my IMEI changed, so is my efs.
I hope there's a workaround and its reversible.
Thank you again.
Sent from my GT-I9300 using xda app-developers app
if you did not back up your efs folder and if your imei has changed than most likely you flashed a newer baseband from mg4 mg5 or mg6 roms . and then reverted to an older baseband which can no longer read your efs folder. some people have been able to fix the problem by flashing once again an mg4 or mg5 or mg6 rom. perhaps doing this will allow you to regain your network connection and efs folder.
I checked. My IMEI and SERIAL Numbers are still the same with what's written on the back of my phone.
I've also confirmed on the Android Revolution HD 29 thread that it doesn't change the efs.
Any other ideas guys?
Thank you.
Sent from my GT-I9300 using xda app-developers app
android revolution 29 modifies the efs folder so that it cant be used by older modems. it uses the mg4 baseband. since your imei is intact i am guessing that you are either back on android revolution or a rom that uses either mg4 or mg2 baseband as those are the only basebands that will work with the modified efs folder. if you still have no network but imei abd serial number are intact then check your apn settings to see if they are correct and compatible with your carrier

Android Revolution HD 29.0
--- release date: 31 July 2013 ---
•Based on latest official Samsung 9300XXEMG4 firmware
•Other minor changes and fixes
•Included and updated custom components:
I see. Yes, I am on AR29 right now since it's the only ROM I have that's has a working cellular network.
I made a recovery (cwm) backup when I was on SuperNexus, which I had no network problem with.
1) Can I extract my efs from there & flash that? Or...
2) Can I try and restore that backup without any major problems?
My ultimate goal really is to go back to my Stock ROM.
Btw, thank you so much for your patience Sir.
Sent from my GT-I9300 using xda app-developers app
cwm does not backup efs . for efs backup use hc-ktool from play market and efs pro. make backups and leave them on your ext sd card as well as your computer. you can flash any stock firmware from sammobile.com as long as the rom is in the "G" series. for example mg4 or mg5 or mg6. any rom from a-f will not read the efs as they all use older basebands. basically you cannot go backwards.there are many roms now that use mg basebands if you cant find one that matches the csc for your country than try any other firmware as long as it is a G rom or higher.
Very educational Sir.
Thank you again for your help.
It's much appreciated.

I too use supernexus and stock. Also had this issue. You can still use any rom , you just have to flash a mg4 onwards baseband. For example, you can be on the supernexus ROM with mg4 baseband and you can make calls as usual.

flash a stock f/w XXEMG4 or later via odin and then root it. then flash any custom rom via recovery(CWM touch or PHILZ). the custom rom(any AOSP rom)continues to use the same modem you have on the stock f/w.

EFS Pro

Hi,
I've got an Galaxy GT-I9300 and recently I flashed some custom roms, with no problems. But at the last time, my IMEI has changed to a generic and I received the 'Emergency Only'. Fortunately I had a backup of my original efs folder, made by KTool. So I restored it using some tutorials from xda and other forums and my original IMEI is back.
But it's frequently losing signal, then the signal returns with 'emergency', then gets normal, then lose signal again and etc.
My question is, can I restore an efs.img or *.tar.gz made by KTool using the EFS Pro? So I could wipe the efs folder and restore the backup, clean...
I'm now with WanamLite XXUFME7.
Sorry for my bad english :/
Thank you all!

I was using the UBEMH2, Omega Rom 4.1.2. When I flashed the Wanam XXUFME7 (4.2.2) it broken IMEI and got 0049..
Now it seems good, I haven't noticed no one or very few conection losses.
One more question, my counter is 1 and I have a custom recovery + custom rom. When I used Triangle Away to reset counter, even with stock recovery, the counter didn't get 0.
What do I need to do?

AFAIK this will happen unless you are running both a stock kernel AND recovery.
And how do I know if I'm with a stock kernel? Or by using a custom rom, the kernel is automaticaly custom too?

I had the same problem a few days ago when i was flashing cm10. Just restore back to stock firmware, root it and back up efs folder. then try to flash any rom and just restore the efs back up you did with stock firmware. it should be fine. if it is not working still, try to flash mg4 modem.
Thanks for your explanation!
Since yesterday it seems be fine, no more connection losses or 'emergency calls'. Maybe it was caused by a problem with my carrier. I'll keep it this way and if the issue appear again, I do what you said.
Can somebody help me with my last question, please?

Do you know if your s3 ever had imei issues, got unlocked through means other than imei code, or did you ever used patched modem (or ariza)?
If yes, stay on 4.1.2, or do as adviced and get a patched modem and kernel for 4.3.
Your efs might be damaged, to stay on the safe side, backup everything before attempting to upgrade or patch stuff.
Ok thanks so do you mean by downloading another modem for my 4.3

Flashing a 4.1 firmware should not corrupt efs, but only if you use EMG4 or later firmware. Anything earlier will not work.
Flash the full firmware with Odin, then factory reset. Backup your efs first.
