Hi
I`m having a weird issue. After updating my S3 i9300 with the stock rom 4.3 from sammobile, i had the common no service isuue. Never lost imei or serial number. Installed the Patched_BUUGMJ3_modem.zip and Patched_XXUFMJ9_kernel.zip. That solved the problem.
I didn`t like jellybean 4.3 so I tried back 4.1.2 but no service appeared again. So i returned to 4.3 patched again and everything went ok again.
After that i tried sentinel v6 rom. Impressive rom. Nice , fast performance and long battery life. Never lost service
But when i try other modem, from odin or Philz i get "no service".
Imei number and serial number always remained OK.
Can anyone ahelp me?
Thanks
I ve discovered that patched modems works flawlessly. Why ? Anything remains wrong in my phone?

Hi,
In my ignorance I loaded on the i9100 rom from Samfirmware XXLSJ, and it loaded ok. However the modem doesn't work. The symptoms are: connects ok to 3g network, however will not txt/make phone calls, the phone reports "not registered on network"
So, I tried flashing the XXLSJ JB again, this time with another modem, one that is supposed to be for the T variant, I'm in New Zealand by the way and use Telecom. Same deal.
No problem i thought, ill simply go back to an earlier official Telecom version on ICS. However, this now hangs on boot up on the S logo.I went back to an earlier one, that one also hangs. I went back to Gingerbread, that hangs on start up also on the S logo too.
So some questions:
Can i run jellybean and use some new modem?
If not, can i put it back to original 4.0.3 official firmware without it hanging?
I'm using Odin 3.07 to do the flashing.
Thanks in advance, i'll just be happy with a working phone at this stage :silly:

Sorted, ran the old firmware back on from Telecom, went into recovery mode and did a factory reset. all seems better.
I flashed a stock 4.0.4 ics ROM for my s3 but I noticed that the mobile network is not working
When I dial a number it says "mobile network not available"
And of course the mobile data doesn't work
When I tried to upgrade it to the latest 4.1.2 it refused and said that there is a problem with the network
I flashed a 4.1.2 stock ROM but the problem still the same
When I checked IMEI I found that there is an IMEI but it's different from which written on the back of the mobile
I remembered something:
Before I flashed the 4.0.4 ROM i had CWM touch recovery v6.0.1.2 and I played in it with no experience
But of course when I flashed the 4.0.4 ROM it returned to the stock recovery
Any help ??
Please
And sorry for my bad English
addition
I'm now on the 4.0.4 Rom again and the problem still the same
Sounds like you flashed your phone without first understanding the basics and backing up your efs folder.
Return to the latest fully stock rom and send for repair.
Well couple of ways to restore imei if you got backup : http://forum.xda-developers.com/showthread.php?t=2393289
If not , try this as last resort : http://forum.xda-developers.com/showthread.php?t=1264021
If even that doesn't work , reset your flash counter , flash stock firmware and pay a visit to Samsung care.

Hello,
I've been facing this problem for days now, tried almost everything and still no luck, so I'm sorry if it's been asked before, but I'm truly hopeless.
Right now, my SGS3 works only on stock ROMs. Every time I try to install a custom ROM (JB or KK) I have a problem with the signal - either baseband, IMEI and everything is "unknown", or everything is good (IMEI not "0049...", there are full correct APNs) but it still displays the "error while searching for networks" message.
Fortunately (as I realized on other threads),I can always go back to square one, flash a stock 4.3, with no problems with IMEI or anything, but, you know, stock sucks.
I tried installing every modem I ran into, but nothing helped. Is there a secret step from stock to custom on samsung devices I'm skipping (I'm an ex-nexus user...)?

When you install a custom rom, based on samsung 4.3, do you have emergency calls only/no network?
If yes, install Boeffla kernel 5.3/or beta 5.4 because Boeffla is a patched kernel i.e. it can read patched modems, and then install a patched modem .
From the on you will have your network (no emergency calls/no network problem) and signal should be good.
But first backup your EFS and store it on a very safe location, you have ann app for that, k-Tool on Playstore (requires root).
Hi guys, I must have read a hundred posts about this issue to no avail.
I recently rooted an old S3 GT I9300 using CF-Auto-Root and Odin. I was sure I backed up the EFS folder, but it would appear I didnt. Now I am runnning the Paranoid Android 3.0 ROM on the device with absolutley no mobile network/signal and although i have the IMEI written down the S/N seems to have changed to a generic 15 digit number as opposed to the original RCF**** or whatever it should be.
Ive tried Kies and re-installing a stock ROM which is both hard to get hold of and doesnt seem to want to unzip from CWM Recovery even after cl;earing the Caches and doing a factory reset. I've also tried re-writting the bin file using a hex code app and terminal with no luck, and EFS Pro only seems to make me think ive restored the EFS by backing up the already corrupt one and restoring that....
It is possible to rectify my EFS issue (nv_data.bin file I assume) with only a written down IMEI and no serial?? if so please advise... as Im seriously stuck and although ive considered using a friends efs folder im sure this is probably illegal...
HELP, Thankyou
oh..and...
It occurs to me that the guy to talk to is spocky12, yet i have yet to pm him pending your advice.... thankyou for any help i may receive..
Hi im also in the same position ive tried loads of stock roms for the UK as thats where i am... to no avail ive tried the original 4.0.1 rom all the way up to the latest 4.4.2 rom and each time the imei number is 0000999......... ive tried modem patches most of which are from looking through the xda site but nothing seems to work.... i could never back the efs up as when i had the phone it was in a constant loop so never knew which software/modem/firm it actually had on it as i could not get past the samsung logo. but since i have flashed latest android for the phone it will boot in fine just wont connect to a network and imei number is wrong ive been days trying to figure this out :crying::crying: Please Help!

Hi Dejay, its good to know im not the only one. have you tried using the Kies program to reinstall stock firmware, did that change anything? Also not sure if you tried this http://www.youtube.com/watch?v=JqLK_2I-SBM method but it didnt work for me, the HEx lines he refers to dont exist in my nv-data.bin.
Coincidentally, thats exactly how i acquired this issue, it stopped booting so i factory reset deviced, then backedup and rooted, then installed custom ROM and somehow lost backed up /efs .Im now showing an 000049 IMEI and tried modem patches, stock roms etc. and no luck. my serials all messed up too and i cant connect to any form of mobile network.
I just changed ROM again as i couldnt get the right Gapps to flash with Paranoid Android Rom 3.0 - now flashing Dirty Unicorns v3.8 from here and all working beautifully except no signal, wrong IMEI and S/N - I am by no means a PRO at all this and so im rather stuck like yourself..
Hopefully we'll be saved?!
I have a I9300 that is not getting any network, the IMEI is 0049... and the serial number is a string of zeros. It was previously running stock 4.1.2 but I wanted to upgrade to at least the latest official ROM - 4.3 and thats how I ended up in this situation.
I've been a Linux user forever and I've owned and flashed a few Android phones in the past but this is my first Samsung Android handset and so the first time I've been bitten by efs. I did lots of reading before attempting the upgrade so I knew to backup the efs partition before doing any flashing. I did this with ktool but restoring my efs backup to various ROMs hasn't restored my network connectivity.
I'm on the 3 network in the UK so when I've been using Odin to restore stock ROMs (I've tried restoring both 4.3 and 4.1.2) I've been using the BTU versions ie
I9300XXUGMK6_I9300OXAGMK6_BTU
I9300XXEMG4_I9300OXAEMG4_BTU
I have now spent four full days reading and trying various solutions suggested in an array of threads on this forum, I've read all the stickies in http://forum.xda-developers.com/galaxy-s3/general/samsung-galaxy-s3-sticky-roll-thread-t2344125 plus many more threads and now I've just about given up. I've tried flashing various unofficial ROMs too like CM 10.2, 11 and RevolutionS5 but they all have no network.
My phone is not in factory mode and I've tried zuluman's patched kernel/modem with 4.3 without any luck. I've tried factory resets, deleting /efs, changing the permissions of and editing nv_data.bin with a hex editor amongst other tricks. No go.
So it seems my only remaining option is to take / send my phone to be repaired or fork out for one of these hardware devices that claim to be able to repair IMEI issues. Problem is then I'm back to square one, I've not learned what I wanted to about my phone (how to safely reflash/upgrade it) and I'll be stuck on whatever the repair shop leave me with.
I'd much, much rather fix this myself as then that opens the doors to experimentation, it will prolong the (so far all too brief) life of my phone and be much more satisfying. Until now I thought the SGS3 was (is?) a class phone and I think its much better than the Nexus 4 I had previously, despite inferior specs in many respects.
I'm sure its possible to recover from this without buying dedicated hardware or at least it should be..
I bought my phone 2nd hand less than three months ago but its no longer under any warranty. Another thing that could be an issue is that I was sold it without a box and there is no IMEI printed under or on the battery.
Thanks for your help!
It would seem from my experimentation that reflashing stock ROMs with Odin on the I9300 doesn't affect the efs partition, or at least the stock ROMs I've been flashing don't repair/recreate efs.
I'd be perfectly happy using the Samsung generic IMEI if it will let me connect to my phone network. If anyone knows how might enable that, please speak up!
Same problem encountered before until now...
This are when the problem starts.
My GS3 International had CynagenMod stable build.
1. I've noticed one morning that my GS3 is stuck in a bootloop.
2. Tried reflashing the stable CM ROM, but still stuck n the bootloop.
3. Tried flashing my stock rooted firmware from my TWRP backup.
- after this, I've noticed that only emergency calls and not registered on network always appears.
- my IMEI becomes now generic with 0049...00 but with serial number.
4. Tried sending it for repair in our local cellphone repair shop. Network signal is fixed now but it always ask for permission for the radio. So battery drain is massive.
5. I didn't send it back. Tried to fix it myself. Installed the stock firmware 4.3 using jellybean. To my surprise, the IMEI and serial number comes back. But still no network signal (emergency calls only).
Lastly, still looking for a fix. If anyone had a fix for this one this will be a great help. Also tried restoring/updating through Kies. All the process I took had failed.
Not sure if the problem was the EFS/IMEI or the modem or radio install from the firmware I just installed.
For now, I'm using the stock 4.3 firmware. The only problem now is the network signal. Any suggestions or fix is a great help. TIA!
I have read of people fixing the no network by flashing a known good efs image but I suppose it would have to contain a working generic IMEI. Please PM me if you have such an image for a i9300. I'll have to find such a thread again and get PM'ing.
I've been disappointed by a few things in trying to upgrade my SGS3.
* There is no well documented fix for this EFS/IMEI/no network issue
* This issue seems to be very common for SGS3 owners who have attempted an upgrade to 4.3 or flashing alternate ROMs yet there is no mention of any of this on
http://wiki.cyanogenmod.org/w/Known_Issues_page_for_i9300
and
http://wiki.cyanogenmod.org/w/SGS3FAQ
There needs to be.
* It doesn't seem Heimdall is able to flash a tar.md5 in one hit like Odin can which is a shame for us Linux and OSX users
Great phone but not for hackers and tweakers it seems.
Sounds like the efs was already corrupt before you tried the upgrade, probably a previous botched repair which only worked on 4.1
Take it to a repair centre and pay for them to recode it for you, there is no other fix. Make sure it connects on 4.3 before you pay.
Suggestion: flash a firmware older than MG4 and let it update OTA or by KIES. Generating the efs-v2-data may solve.
the battle rages on...
rp158:
That sounded like a good suggestion to me so I used Odin to install I9300XXELL4_I9300OXAELL4_BTU, which predates MG4. Because the aim was to try an OTA update, I did not root or flash a custom recovery as I know they don't like that.
Like all the ROMs I've tried since my prob, it installed fine but I get no network. After connecting to wifi I first tried OTA via Settings -> About Device -> Software update -> Update but it just says "Failed to update firmware due to network or server problem". I can browse the internet fine so could this be a problem with Three (my telco)? I've heard of some providers blocking OTA.
So next I tried Kies (not Kies 3) under Windows 8. I went to Tools -> Firmware Upgrade and Initialisation but I just get the error 'GT-I9300 does not support initialising'. Fail, fail and fail!
I've yet to run 'Triangle away' and so I have several flash count points listed on the download screen. Could this stop OTA from working? Is there a limit to the number of flashes you can perform before something nasty happens? I presume its just something retailers check before they refund or repair phones.
Something else I noticed while fighting my phone today was that recovery says the CSC code is now KOR. Could that stop OTA working?
Likes me a good idea to run 'Triangle away': I think there is no max. count for flashes, but perhaps counter>0 and status=custom block the update-procedure. So try after unroot both methods again. (CSC-code I down't know.)
Whilst still running I9300XXELL4_I9300OXAELL4_BTU, I rooted it then successfully ran Triangle Away to clear the flash counter before running csc changer to change my CSC to BTU (from KOR). I would've changed it to XEU but that wasn't an option. I checked that worked fine, which it did, and running CSC changer also (conveniently, in my case) un-roots your phone.
After that I tried updating via both Kies and 'About Device' software update but both just gave me the same errors as before so scratch another idea off my very long list then.
Then go to #5

Sorry, too short. Post 5 = repair by Samsung.
So, if I choose to get my phone fixed, has this proven that I will be unable to flash any alternate ROMs on it without losing my network/IMEI/serial again?
Maybe I should've backed up my EFS with philz recovery or dd insteal of ktool, then I might not have ended up in this situation?
Maybe the US/Qualcomm models of the S3 are safe to flash with alternate ROMS whilst the Exynos-based models aren't?
Can anyone recommend a good repair service in the UK if my local repair shops can't help?
Thanks for your suggestions rp158!

No, that's unnormal. But read before flashing, what users say (some beta's or nightlies are buggy).

Probably. I suggest Philz, TWRP or by TerminalEmulator.

Official Samsung repair-service.
I thought Philz was the only recovery that gave you the option of backing up EFS? I didn't think TWR supported EFS backup/restore? CWM doesn't.
TWRP can, of course.
A corrupted efs can also effect the stability and use of wifi as mac address etc is also stored there.
Check if there is a backup of your efs. Some roms make a backup of it also - neatrom for example. Try flashing xxemg4 or later baseband to see if it fixes it because after having the later bb you also have efs v2
FIXED
Thanks to everyone who made suggestions in trying to get my phones connection back. Its working again now. My 0049 IMEI has gone, my real IMEI come back and my serial number has returned so I can make and receive calls again!
The thing that was preventing my connection and leaving me to suffer the dreaded 'Emergency Calls Only' and 'Not registered on network' errors was nothing to do with EFS but because I had an incorrect CSC. I had flashed stock BTU roms instead of H3G, which is what I should've used being on Three. As soon as I flashed a rom with the correct CSC, my IMEI and serial numbers both returned and this allowed the zuluman patched modem / kernel combo to work. I'm now happily running 4.3 whereas I was previously on a rooted stock 4.1.2.
There are literally 100's of threads on the S3 forums here with S3 owners ending up with a generic IMEI and no serial after attempting a 4.3 upgrade and the standard response is nearly always 'your EFS is probably corrupt' or 'your EFS in the wrong format'. That will be the case sometimes but I'd bet that more often than not the EFS is fine (if updated) and users have flashed a CSC for the wrong region for their telephone network.
Key tools in getting this prob fixed that hardly get any mention are the csc changer app (downloadable via Play but requires root and also factory resets/unroots when run) and A.S_id's rescue firmware
http://forum.xda-developers.com/galaxy-s3/general/odinfirmware-sgsiii-i9300-prerooted-t1825272/
I'd recommend I9300 users flash A.S._id's ROM if they can't find a firmware with the correct CSC for their network and/or csc changer doesn't restore their IMEI and serial.
Lets fix these forums by getting this info into the FAQs in both the general and QA stickies because I know it to be missing hence the endless invalid IMEI / no network postings.
I'll be back shortly wth more details and suggested additions to the S3 FAQs / stickies.
Thanks all!
I've ended up running A.S._id's 4.3 deodexed 'stock' ROM w/ Boeffla 5.3 kernel and zuluman's patched XXUGMK6 modem.
When I used zuluman's patched XXUGMK6 kernel, I would experience small but frequent glitches in 3G streamed audio. I don't have this problem with Boeffla 5.3.
I'd also highly recommend stock TW users turn off smart screen to massively increase your battery life very easily.
