Hi all,
Been facing a weird issue ever since I flashed official 4.3 (NB6 with NA8 baseband) with Odin.
I've been able to flash roms back and forth earlier, but ever since the "official" 4.3, I no longer get network signal in KK roms. IMEI is empty and baseband is unknown. WiFi works fine though.
Tried flashing different modems but nothing works. The closest I got to getting a signal was for 1 second and then dropped (keeps getting and dropping). Searched the forums but it seems to be very rare.
Always have to restore to official 4.3 via Odin to get a working phone
Any ideas on this or maybe Sammy doesn't like me anymore ?

PS: I tried sammy's 4.3-based roms and all was ok, but the official update really messed things up bad.

I had seen the thread earlier but it doesn't mention much except cm 10.1 and "some" setting lol.
Firmware is right (UAE) according to sammobile. I will look into CSC though. I used to be able to flash from official 4.1.2 to TW-based and AOKP-based 4.3 and 4.4 as well, but the official 4.3 firmware was bad news (pretty smooth rom though)
I'm guessing that the NB6 fw hampers baseband/radio to prevent KK roms from reaching S3 users. Kind of like a hidden Knox or something.
~ RazorMC
Tried CM 10.1.3 but no signal even with patched modem MG4.
This is really frustrating lol. I got the S3 to play with roms and now it's over?
Any other ideas ppl on what I could do for this?
~ RazorMC
This is rather an EFS problem than CSC.
Read the EFS threads.

One thing I came across was to downgrade efs from v2 to v1 using the rescue firmware. I don't know if that is safe or will it even work.

Install Samsung kies 3 from here
http://www.samsung.com/uk/support/usefulsoftware/KIES/
Run kies then go to Tool > Firmware Upgrade and Installation
Follow the on screen instructions, this should completely reset the phone to a working condition.
MK6 is stable
Try to use MK6 complete suite, then apply MK6 patched modem and kernel not only patched modem. I don't know why people say flash MG4 modem, it will never work alone. You must need patched kernel to make it work or use ariza patch in older releases.

I prefer Odin over Kies any day. It's better for flashing imo.
Point is, I can use stock 4.3 rom without any problems, but my issue is that I can no longer change to non-TW roms, esp KK.

Gonna try this now. I'm aiming for KK roms, so I guess Ariza won't help me here.
PS: I can get stock 4.3 without any problems. The signal problem occurs in non-TW roms only. I wanted signal on a 4.4-based rom.

can you tell me what error is thrown????
(i) you have CWM r8?
(i) download a cwm flashable MG4 Modem, looks like your phone has an EFS issue (had this issue once).

I don't get any signal on KitKat roms. IMEI is empty and baseband is unknown in "About" section. That is my issue.
Stock 4.3 works fine for me
I've tried MG4 and MK6 modem and restoring efs via Philz Recovery 6.07.9 but no luck. I get a network signal that keeps dropping most of the time. This is strange because I haven't come across this problem before. Everytime I have to flash stock via Odin.
I need to find out why this happens so I can help others if they have the same issue.
EFS is ok and not damaged at all. The problem is that the system can't read the EFS, but I can't figure out what I need to do to get it to work.

are custom 4.3's working fine mate tried any????
[SOLVED]
Problem: Upgraded to official 4.3 and since then I have not been able to get network signals on 4.4-based roms. Stock 4.3 works fine.
Solution: Installed stock 4.1.2 (even though people said it doesn't work). Lost my signal and IMEI became 0049. Then I installed the patched MG4 modem and got imei and signal back. Then upgraded to Resurrection Remix rom (without GApps first) and still had signal.

Glad u found a fix
Sent from my GT-I9300 using XDA Free mobile app
Hi,
I'm in the exact same situation, stock 4.3 work's fine but every time i flash some 4.4 rom, i lost imei / baseband (generic imei and unknown baseband) and the phone is just useless.
After i flashed a 4.4 rom and lost signal, i tried to flash every modem / patched modem that i could find on xda but no luck.
Any ideas of a method that would allow me to flash any 4.4 or 5.0 rom without losing imei / baseband ??
Thx
As you found this long dead thread why not try the solution they found?

Because I cannot get my imei / baseband back after flashing the modem on top of 4.1.2.
So I was wondering if there's anything else to try in my situation (stock tw 4.3)
Anyway, Thx for your help...

I have an i9300 with a blank efs folder. The phone corrupted and was stuck in a boot loop. This happened when battery run out while file sharing was in progress via bluetooth to another android samsung. I flashed it with 4.22 android jelly bean immediately XXUFME3 but it remained stuck on boot loop, I never backedup efs file. Later found the original ROM although it comes up as custom rom, which is i9300XXEMB5_i9300OXAEMB5 but still no luck as it stuck in boot loop. My sister has the same identical phone both were purchased together in Dubai. I did factory reset etc, no luck still in boot loop.
I later gave it to a mobile shop who flashed it with a rom for free, didn't charge me because it came up as imei null/null and baseband unknown. The phone now boots and has Build number of IMM76D.I9300BUALE6 and is german language I believe. I had read some threads by now and I immediately rooted the phone and backed it up, but my efs folder is blank.
Last night I flashed the phone 2 times with i9300xxemb5 rom and rooted it and it still boot looped even factory reset or cache delete don't solve boot loop, Then I restored the working rom of build i9300BUALE6 from CWM and powered phone on and got a baseband of i9300XXEMB5 and Build of i9300BUALE6 also got an imei of 004999xxxxx0000/01 and the phone found the network and my efs folder which had been blank all this time was full of files. In my haste I realized the sim was not plugged in and removed battery, when I restarted with sim, baseband was gone and imei was null/null. I repeated my steps in hopes I could get this fluke opportunity but nothing yet. Was this a miracles I didn't seize by not backing up the efs folder?
My sister's phone is an identical model bought together with mine is,
AP:i9300xxemb5
CP:i9300xxemb5
CSC:i9300oxaemb5
So my question is I need the original stock rom for my sisters phone that won't get stuck in a boot loop on my phone
My phone is now
AP:i9300buale6
CP:unknown
CSC:i9300vfgale6
Also can this be fixed by backing up my sister's efs folder or backing up her phone and flashing it on my phone. I can't get warranty for this phone now since it has binary counter of 12, don't have proof of purchase and also I am not in Dubai but in Africa. What Rom file should I try to flash. Also because this is a custom rom I am not getting samsung serial port in device manager can't use NV writer. Any help is appreciated.
If you don't have an efs backup then you need a service centre, you cannot repair it. Trying to use another phone's efs folder won't work and is illegal in many countries.
Read the sticky on efs:
http://forum.xda-developers.com/showthread.php?t=2393289
If its a custom rom their is a very small chance that it included backup pf EFS .
Look for EFS tar file on phone .
I say slim chance and judged by the OP probably no chance .
004999xxxxx0000/0 that's just the generic non working IMEI .

Sorry to hijack this thread but I dropped my S3 i9300 on water and have the imei null /null and baseband unknown problem, therefore SIM cards are not recognized. Do you think my problem can be solved by doing something without taking it to samsung service? Meanwhile I ordered a SIM /SD tray replacement but my bet is it won't solve the problem.
Thank you.

hi from what you explained it seems that right now your phone has no baseband. One thing you can do to possibly recover your imei and network settings is to flash a stock rom that uses mg4 or mg2 baseband. use a rom from sammobile and flash with odin make sure you use a rom with an mg2 or mg4 baseband. good luck

A custom kernel has no connection with the lost of IMEI or it's a solution for the recovery of an IMEI. So no, no custom kernels will help you with your problem.
Either try ashraf's suggestion or ultimately bring it to a Samsung service center for repair.

You can try but i doubt that it'll restore your IMEI. If that doesn't work then you have no choice other than to bring it to Samsung for repair.

I don't know about perseus kernel but I don't think it will help. your imei and efs foder was intact before flashing4.2.2. I understand that the problem began before flashing 4,2,2. but if you ever had a rom that used an mg4 or mg2 modem and then used an older modem your phone would lose its network connection and would probably display a generic imei number. if it says null usually that means it is corrupted or no modem is installed . either way if you send to service center you need to flash a stock rom and reset your flash counter . since some people have recovered their efs and imei by flashing newer modems or firm wares that use them why not try it before sending phone to service center

Thanks but you didn't read my first post. I did not flash any rom (or even root) before the problem, which started from dropping the phone on water...so I have no warranty left This means I can take the phone anyway I want (custom kernel, rooted) to samsung service cause they will charge me anywat.
But I think I will try to flash a rom like the other user sayd because I flashed the Perseus Kernel and the phone is now unstable and reboots randonly...
Cheers
my mistake that post was for the op of this thread
I don't care anymore that my original answer was
deemed not acceptable enough and warranted a second opinion. I am once and for all, going to put this nonsense to bed.
If you lost your imei because you submerged your phone in water it is a hardware issue. It is INCONCEIVABLE that flashing a rom, kernel or baseband will restore the imei. A SOFTWARE solution will NOT repair DAMAGED HARDWARE. This is obvious!
If your Blu ray player cannot read disks because the disk tray fell off, upgrading the laser driver wont help. This is exactly the same.
Depending which hardware failed, replacing the tray may help although given the symptoms, it seems much more likely that your radio stack is damaged. Take it somewhere to get it repaired and stop wasting time pretending software will fix your issue. It's IMPOSSIBLE

I see you're still struggling to understand this.
2) If the ROM is MG (M = 2013, G = July) or Newer, the ROM changes EFS format. This means if you flash one of these ROMs without backing up your EFS, you are restricted to using an MG modem or newer as only Modems from July 2013 can read new EFS format. I'm really not sure how I can make this any simpler to understand.
However, if you flash the modem separately from the ROM, EFS is not changed. So for example, if you are on ME7 ROM, you can flash MG2 modem without affecting EFS.
I hope this is clear now.

Dear rootSU,
you've been very patient with me and i really appreciate your efforts at making me understand and i've understood a lot because of you only,but what puzzles me is that
1)this restriction is for those who've not backed up EFS whereas in my case i had in the very beginning only made an EFS backup.
2)and if i flash ME7 ROM then since am coming from MG5 to ME7 my imei would again be corrupt and i'll have to flash MG2 baseband...right??even if i have an EFS backup(EFS PRO won't restore my imei in this case despite a backup)?
thanks in advance
SOLUTION:
Flashed this patched modem:
Code:
http://forum.xda-developers.com/showpost.php?p=45038238&postcount=466
Now back to network
Also PLEASE BACKUP YOUR EFS!! BACK IT UP!! ASAP!!
I flashed a MG4 rom and after that the imei is changed. I do not have efs backup.
The IMEI has been changed to a new one and the mob is showing emergency calls and not registered on network.
The Serial Number has changed to 00000000000
I cannot make calls or text other than that the mob works ok.
The imei was 353xxxxxx and now it is 3591xxxxxx
Can anybody help?
Also the rom was sammy not a custom rom so i got no backup of EFS.
I tried using MG4 baseband but same error.
Ariza patch simply nulls the imei and hence not working for me.

If your rom comes with a modem, you'll need to reflash the patched one. Otherwise, no action to take.

You flashed?

Yes i flashed the patched modem and the network is back online and up until now the phone seems pretty good and batteryl life is excellent.
Also I am on stock JB firmware for now.
I'm having the same problem. Did you flash modem by downloading and pasting into an sd card and then by using TWRP on your phone?
I've got the same issue, was running on stock 4.3 and flash a different stock rom on it , lost my imei and baseband now am stuck with no network , looked for solutions all round but non is working .. didn't back up my EFS too . Can anyone help with this ?

Depends what you mean by "different stock rom".
If you flashed backwards to 4.1.2 then your efs isn't damaged, it just can't be read because the encryption keys changed at 4.3. You cannot downgrade without an efs backup from 4.1.2. In that case you should be able to flash back to 4.3 and your efs will be ok.
You can also try kies emergency recovery. Depending on your os depends on which kies (2 or 3) to use.

Yesterday I updated my i9300 to android 4.3
Baseband version I9300BUUGMJ3
Build number JSS15J.I9300XXUGMJ9
..and since then I haven't had any reception. My imei number, serial number, and everything else is same and still there, but I just can't get it to get reception again... When I go to my Mobile Networks, it says registered on network, but again, no reception. Then I tried installing the modem BUUGMJ3 with odin which didn't work. What can help? Stock firmware? Please help.
Thanks in advance.
currently experiencing the same issue mate. I can't seem to find a workaround/solution for this -__-
Is that base band supposed to work in your country? Find an modem later than EMGx, without a RIL, for your country and install that to test.

I've probably made a big mistake there, no it's meant for mine country, it's for the county near mine, Croatia, but I read somewhere that this doesn't matter.. :/
And by 'later than EMGx' I'm not sure what you mean, but I've flashed EMG4 modem which didn't seem to work.
Found something about flashing a previous modem and restoring your EFS folder, but I do not have my EFS folder backed up - I forgot to.
A few days ago I paid about $30 for a repair on my phone, I don't really want to send it off for repairs again, I really wonder if there is an fix to this
Follow the guides in general forum, stickies on how to flash back to 4.1.2 stock rom. Make sure it's at least EMG4 base band.

how about your IMEI/Serial numbers? are they still the same before you downgrade and flashed the XEMG4 modem? mine are the same with SN/IMEI so I guess that's why it worked. I just took the risk cause I was really pissed experiencing the lag and the battery drain in 4.3.
Do factory reset from settings option in touch wiz, make sure the imei and serial number match the label under your battery.
If still no good then try another SIM in your phone, final steps would be restore efs backup then repair centre.

Well it's all the same as it used to be. Could it be that the modem I had before EMG4 changed the format of my efs folder?

Do factory reset from settings option in touch wiz, make sure the imei and serial number match the label under your battery.
If still no good then try another SIM in your phone, final steps would be restore efs backup then repair centre.

Did a factory reset, imei, s/n same.
Android 4.1.2 EMG4 modem still no reception.
It seems that MGX modem has change ur IMEI from /efs1 to /efs2. MGX modem seems to support only 4.3 roms (due to some security issue).
It is not recommended,but u could flash an older rom with modem (get from www.sammobile.com) then restore an efs backup (if u did some) from /efs2 to /efs1

Ariza patch only works on older modems (efs v1 modems). So, that wont help.
You said you flashed the zuluman modems but.... did you flash the patched kernels too? You need the patched kernels for the patched modems to work. I don't know why, but that's what zuluman says (according to him, the kernel has a modem signature check and it wont work if the modem was modified).

Here are all the patched modems and kernels made by zuluman.
https://drive.google.com/folderview...&usp=sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8
In my opinion you should flash the latest official firmware and download the appropiate modem and kernel from that google drive.
You can download the latest official firmware from the general section of this forum.
Good luck.
Remember to always have an efs backup!
Great thanks!

Flashing the Modem + Kernal after rooting the Phone works for me. I have flashed it using CWM.
Thanks once again.

After this i had no signal. ...
When i found this thread i was so happy. BUT!!!
i downloaded all the modem and kernel files from the google drive and wanted to flash them (Patched_XXUGMK6_xxx.zip) with cwm recovery (latest version).
whenever i want to do this, i get the following message and the update aborts: "E:Can't copy META-INF/com/google/android/update-binary"

hmm...
can nobody help me? ...
sorry for spamming, but i've got a problem without a phone
greetz,
Carpe.
You said your imei & serial is ok but you cannot register to network. Have you paid your bills?
But if it's corrupted serial number.
Try this guide.
thx for your answer.
Payed my bills? ... uuuuuups!
back to topic: i've flashed my phone back to 4.1.2 for the moment. Network seems to work. ... i'll try some things and give a feedback here. ...
You have to flash an Android 4.3 modem for it to work I think but as your on 4.1.2 now I guess it doesn't matter anymore

Hi everyone, my question is, can I update i9300 from 4.1.2 (XXELLA) to any 4.3 version or does it have to be for specific country?
I am curently running XXELLA that is for Poland, I was on XXEMC2 that is for Slovenia, and I am from Croatia, also to mention that original is XXEMC2 from my phone.
Also, is it safe for me to download 4.1.2 BTU XXEMG4 (UK) and flash over my current XXELLA, can i brick my efs? (I think it is an additional option to upgrade from btu version to 4.3).
Will i brick my EFS by updating to official stock 4.3 via Odin? I wan't to get to 4.3 version that supports OTA to 4.3 version MK6 (I heard it has many fixes), but I am scared to lose my network signal.
To sum up, what firmware do i need to get the MK6 update, is there any except BTU, and is it safe to update via Odin so my EFS won't brick.
Thanks.
You need to understand the basics before you do anything, sticky guides in general forum will guide you.
If you aren't confident then wait a week or two until MK6 is released in your country.

It's a good option to wait, it isn't even official for download to flash via Odin, I am just curious over what will or will not happen, so I'm just searching for some direct answers, when I read all those stickies and threads I got very confused.
Can i just ask, will anything happen with network signal or efs if i flash XXEMG4 4.1.2 BTU or MJ9 BTU over my XXELLA with Odin? Just to know..

I'm from Croatia too, and i have MJ9 BTU since day one and my phone is functioning perfectly, so no need to worry about network signal etc.
My recommendation is that you flash a MJ9 ROM with some custom kernel wich will remove the well known wake-up lag and battery drain that MJ9 has. Or you can just wait official OTA update for Croatia if you want. Personally, I moved away from official ROM 10 days after I got my S3. But as the boomboomer said before: read all the stickies to be 100% sure what are you doing
Hi, Before flashing anything or attempting to do anything make sure you read this and back up your EFS, If your already know about the risks then carry on but this is very helpfull. Thanks

Ok, I'll try to flash BTU MJ9 over current XXELLA and will see what happens, I already have backed up my efs and also nand backup, but i think i can lose my efs/no network because my IMEI was repaired with z3x box, I heard that if it is repaired with z3x i cannot upgrade nor downgrade anymore, will see what happens, if anything goes wrong i have z3x so no need to worry i think, i'll also try to flash mg4 modem or patch it with Ariza if i will lose my signal..
There is a thread with patched modems for those that previously used ariza patch, which should enable you to connect to your network.

I found only for 4.0 and 4.1.2 but not for 4.3 modems, and they are not patched, for patched i read that ariza patches modem but that it doesn't work with 4.3 android.
Can You please provide me the link to thread of patched modems?
Thanks!
Edit: I saw some patched modems for 4.3 but there is not MJ9 for i9300, also i tried extracting the modem.bin and patch it with zuluman patch and install through odin (put it under Phone section) but it fails, it says in the log something with bootloader, please provide me the patched M9 modem.
Edit2: Succesfully flashed patched MJ9, now IMEI is null/null, i'm getting really tired of this, going to take it to local servicer to update it for me, i think repairing imei with z3x box got it all messed up. And also finnaly i tried flashing the original modem back that gave me my IMEI back and than patch with ARIZA, nope, imei was 0049 etc.
Hi,
After flashing stock s3 rom my sim card is not being detected. i know the sim card works because i tried it on another phone and i have a feeling my efs file has been made corrupt as my imei has been completely changes to 0049xxxx. Also i cannot connect to any wifi network but theyre being found . ive looked everywhere and found no answer. Please help me on how i can fix it.
I'm guessing that you made no efs backup? Do your phone's cellular functions or wi-fi work while running a custom rom? What kind of GS3 do you own (i9300 or i9305?).

You cannot go backwards to 4.1 with out a efs v1 back up. Somewhere in 4.3 samsung updated it to v2.
Without a back up you can only use the latest 4.3 and upwards.
