Hello,
My problem is very big.
I flashed my S3 back to CM10.1, and now i have not signal.
My IMEI is the IMEI from the first day.
I Have not signal on Stock or other Roms, what is the problem?
I have a ktool EFS backup.
Have you the correct modem and CSC for your network ???
Did you configure your network settings .
No signal suggests wrong IMEI .
Damaged EFS folder = restore your EFS backup
Or a hardware problem return to service .

All are correct, i would return it..

Bearing in mind that you have no warranty with root custom rom and rom counter above zero.

I don't know, whatever the latest firmware is. Make sure the csc is correct and try different modems
Where i get the modems for that version, it is the 4.1.2 JB i had it before flashing CM10.1.
in the modems thread in General

Service centre or try reading all the identical no IMEI/EFS posts .
But first factory reset and flash a stock rom .

How can I do that?
Read the basics before you flash any rom or mod .
http://forum.xda-developers.com/showthread.php?t=1927113
Your IMEI should match under the battery if you have wrong then restore your backed up EFS folder . If you failed then its a samsung job .
If you did not flash firmware for your region then the modem and or CSC may not be compatible .
Suggest you restore your original saved firmware .

Hello,
I own a samsung galaxy s3 gt i9300. I rooted my phone and stuck to stock modem for a while. I then flashed paranoid android 3.15 on it which still used the stock modem. Then i flashed omega rom on it which changed the modem I guess and now I cannot connect to my local number. My IMEI number is there so my EFS is secure ( I have backups of it too). I tried flashing XXELLA modem first since that came stock with the phone when it came. I tried multiple other modems like XXEMB6 and XXEMC2. But it wont connect to my mobile number. I live in Pakistan and bought it factory unlocked from samsung.
Can someone please guide me as to which modem to flash? This is a modem problem right? Because that means I can never flash custom software with different modems. Or is it a CSC problem?
This is the thread i used for flashing/downloading modems! http://forum.xda-developers.com/showthread.php?t=2076857
First attachment is the stock configuration the phone came with
Second is the new ROM i put in which is omega rom.
I even restored my nandroid backup of the stock working official samsung ROM. But still no connectivity. Someone help please!?

Multiple modems suggests you have not entered the correct network APN settings for your network .
Or Sim is faulty .

Called up the network. Everything is fine on their end. And I was told APN settings is just for Mobile Internet (GPRS/Edge yeah I know Pak doesnt have 3G yet lol). It happened right after flashing the new modem. Any other solutions?

I checked the IMEI. Still there.
Sim works properly on another phone.
CSC settings I tried of many regions (through CSC changer app) from EUR to PAK to even MID (middle east)
As for modem, I flashed stock firmware from sammobile for Pakistan, the latest one, and it still refuses to connect. APN is fine according to network.
P.S. I dont know if this holds importance or not, but I did experience SDS. And my local repair shop (owing to the abysmal samsung warranty policy in pakistan) repaired it. But they did not change the motherboard. They changed the 'chipset' only and upgraded it to 4.1.2 firmware with the sds patch fix. Might be a stupid question, but could it be that the new chip hardware they put in is from a different region, so they had to flash a different regions firmware, and the answer to all my problems could be flashing the one they flashed after i ask them!?
Thank you!
anyone?
Read the rules, do not bump before 24 hours has passed. I will report it next time.

IMEI as under the battery .
A guess is that service centre broke something .

Try (Ariza Pach ) from xda, it solved my network problem. Push Thanks Button if I Helped :thumbup:
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.
No.

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

by highlighting i want to emphasise these points (do let me know have i understood correctly)
1) i'm on stock XXEMG5 and yours is MH1 which means yours is ahead of mine and how's it better or it's just region specific???
2)you are on MG2 baseband/modem does that means you also have to be restricted to MG2 baseband/modem only when flashing roms????
thanks in advance.....

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
Hi guys , so i was having some problems with calls on my gs3 , (i was sending sms and atuff normally, but from yesterday till today i could make calls in the morning, i tried my moms phone and the carrier signas and status seems ok. so i tough it was a modem problem, i flashed "I9300UBEMH2_I9300UBEMH1_I9300UWHEMH1_HOME.tar.md5" from panama and the signal was OK . so i tried to reflash another modem and i got the "no sim card" error. tried a bunch of modems and none of them worked.
So now im flashing the stock one, but as far as i know it wont read my imei because of the panama was MG4 or MH1 it changed the efs format. But i will flash a mg4 modem with the stuck UBELL1 from movistar southamerica and see if it works .
My problem here is , can i flash an mg4 rom make a back up of the efs with ktools and restore the efs backup on a previous not mg4 rom? and it will read my emai ? (this is happening because i didn't made a back up of my original efs)
Also i was wondering, what will happen when i want to install a 4.2.2 again in the future? or a 4.3? i won't be able to do it since i need to use a mg4 modem to have signal? or can i back up a working efs with a mg4 rom and restore the efs back up on a stock not mg4?
#BTW my sg3 is still attached to movistar (is not unlocked)

This is already answered in the thread you said you read.
today i had some idea. But not im not sure about it . So here it is. I am wondering if its completely necesary to use mg4 modems forever on my device to get my imei readen. So is there any kind of method to take the v2 imei readen only for mg4 modems . and make it readable for another basebands modems? like ubell1 ? . i tried installing a 4.2.2 rom, then flashing the mg4 modem. once the imei got readen i made a efs backup with HCk tool , then i change rom and restore the mg4 efs backup . But i got nothing . the imei is not being read.
do you know if what im trying to do is possible? or maybe (as i said before) i will have to forever use mg4 modems on my device? .
with mg4 modems im not having problems is just that , it's a pain in the ass being changing of basebands everytime i want to flash a new rom.
You can only use mg2, mg4 or mh1. Basically any modem released since July. Stop living in the past
