Hello guys,I know theres many threads about lost imei/sn/efs after this efs v2 came out,but I was trying hard whole day to get my i9300 back,read like 100threads and nothing helped.
Situation :
I had custom rom (s4 revoultion 4.3 touchwiz) and everything was working well, In meanwhile I got my s4 so I decided to unroot/flash stock rom from sammobile with odin,but I forgot about that efs v1/v2 thing. I flashed rom,everything was working except phone says that there is no SIM card. My phone was factory simfree,so no problems there. I tried flashing all kind of roms(aosp,aokp,cm,tw 4.1.2;4.3;4.2.2), My IMEI and SN are there,and are valid/same as on the box of phone,so I didn't lost my imei/sn. Thanks for your help.
Try your sim in another phone, try another sim in your phone. If your phone won't read the other sim then your card reader is broken.

Hello Everybody,
After rooting and flashing my galaxy S3 GT-I9300 I got some problems. I can't connect to the network and my IMEI has changed. I tried changing the IMEI following the instructions in this guide.
That didn't work. I figured that my phone might be t'mobile branded but i'm still not sure. So i installed a t-mobile ROM. This gave me more problems. The phone didn't start at all. Even charging was not possible.
At the store they flashed the stock rom for me. It does start but still weird IMEI and doesn't connect to the network. I also have these signs on screen (See print screen).
Can anybody help me please? Thank you!:good:
(sorry for my bad English)
Please ask this question in the relevant IMEI thread.

Hello all,
I live in The Netherlands and I had bought the Samsung Galaxy SIII from a telephone provider in the Netherlands.
I had an official ROM for the Samsung Galaxy SIII and everything worked ok.
It was working on Android 4.1.2. and I wanted to flash it to Android 4.3. with Odin. It was the first time I ever flashed something in my life so I was very happy that it seems to turn out well.
But I discovered that I have a big problem on my hands know because my IMEI is completly gone, my phone number has become unknown and my network is gone too!
I still can use WI-FI on my phone but that's it!
Does anyone has any idea how this can be solved?
I am aware that there are simulair posts here with this subject but it didn't help me so for that reason I desided to post a new one for this issue.
Thanks in advance!
Follow these guides if they can't help sounds like a service job..

Well what modem are you using. Please ensure you are using XXEMG4 or above modem.
Read the efs 'know this stuff' thread, it may not fix your problem if you didn't back up your efs folder first -but it contains the reason for your problem and the only answers.

Already a sticky about this, please dont post duplicate threads.
Hi guys, I know this has been discussed a lot but I have no idea what to do next, here's what happened:
So one of my friends bought a used galaxy S3. The next day, he noticed that the IMEI inside the phone was actually different than the one shown inside Android Settings, so I just assumed maybe the motherboard has been changed or something like that. Anyway, I proceeded to install CM10, but after trying it out for a couple of days he complained the device had been crashing a lot and that he wanted to go back to the stock ROM. So this morning I downloaded the right 4.1.2. ROM and flashed via Odin, after which I had noticed I wasn't able to make any calls whatsoever. After reading up on this I checked the SN, which was now 00000000000, bun even after rooting / trying the ariza patch, the phone is not working anymore. I have no EFS backup, and was thinking about trying to flash the modem next to this http://forum.xda-developers.com/showthread.php?p=43946365#post43946365 , is this the right fix? If not, can I actually do anything about it now? Thanks.
Faqs and guides its all posted we don't need identical threads .
Sorry, I know there are a lot of other threads like this one being opened all the time, but even after reading my ass off today I couldn't figure it out, which is why I decided to post here, I would really appreciate a link to a relevant topic, if a full answer is too much to ask. Thank you.

I couldn't find any thread about my situation, so decided to make one and wish to find help for this little problem:
So i forgot to backup my EFS folder, flashed custom ROM and phone got into bootloop. I fixed that but lost my imei during progress.
I sent my phone to repair because I don't have any required tools to rewrite IMEI but now I'm facing a new problem; repairing store has samsung anyway jig but no skills to repair IMEI and they are asking me to help them, so how does repairing IMEI work with samsung anyway jig? I have no experience about that. For the record, i know it is illegal to change your IMEI but my goal is to get the original one back. Would send stats about my phone but it's at repair so all i can say it's I9300 (INTERNATIONAL!!!! NEE) 4.3JB with stock ROM and IMEI is now 0049...
the only thing I can think of is the sticker with your imei is damaged and unreadable therefore the only other place it is written down is on the factory shipped box. Apart from that any further discussions regarding changing or modifying imei are forbidden on these boards

You just need the 4.1.2 MG4 firmware from BTU region . I recovered my imei on i9300 after using this firmware.
here's the link: http://rapidgator.net/file/7a1606232...9e7efe8d0e1cdb
Do a backup of your efs after flashing
Send it for Jtag...
They can fix any imei or bricked device issues..

Questions go in the q&a forum, report your own post and ask a moderator to move it.
We can't help you with imei restoring, take it to a reputable repairer instead.
