is it safe to flash the boot.img using odin? (packaging it as tar.md5)

Pay for a repair, default CWM backup doesn't include efs partition.

Which firmware you are running with?
Check MG4 modem in net, that should solve your problem if you are using Android 4.3

didnt work :/ guess I'l need to get a new phone

Which ROM did you flash exactly that destroyed the IMEI? Happened to me awhile ago, dont remember what i flashed. What i did was, just find a ROM (4.3) which has Aroma with modem selection. I just reinstalled till i found the right one.

No man thru recovery. Search for MG4 modem. There is modem collection in this forum.

Using IMEI of another phone
I have a s5360, which i dont need anymore.. Is it possible to use the IMEI in efs folder of this phone and use it in my i9300, as i have a corrupted/overitten efs?
Thanks!
Malcolm Tanti

download your country firmware from sammobile and flash thru odin.

Hi, what baseband u use before u flash to 4.3 @ 4.4 @ 4.4.2?
U just to flash ur last baseband.. I also had a same problem.. More sadly my sgs3 don't have network coverage. So the solution I take is I flash the last baseband I use & it's work fine

Unfortunately still no Network Coverage. I purchased a nexus 5 now, so I'm not trying to fix it. I will take it to the Samsung retailer and try to get it fixed for selling in the future though

No you don't. Just get the CSC file and flash it. Give it at least a day. If not it could really be the sim fault.

There is a fair chance your efs got scrambled so your imei number is gone. Go to settings -- about phone -- status and check the imei. If it starts with 0049 its fake. You need to restore it then. If you backed up efs just restore it. If not flash stock with csc and should do the trick...

The firmare you need has to have three files
One with code in its name which you put in pda in odin
One with csc in It's name which you put in csc..
one with modem...
It's also recommended you flash with pit in cases like this...
Unfortunately not at the pc right now or would've posted a priper link for ya... will look for it anyways...
You sure you haven't got any efs folder backup?

This is for stock ics lph for i9100 if I'm not mistaken it has the necessary files inside including odin.
Here's a matching cf-root kernel to root after flashing http://download.chainfire.eu/147/CF-Root/SGS2/CF-Root-SGS2_XX_OXA_LPH-v5.2-CWM5.zip
You sound like you haven't got much experience with odin flashing so be sure you read about it before you flash.

What did you do in the first place to mess it up?
I didnt do anything ! Even i havent root my phone either !! M using 2.3.4 Ind version gb.
Can i update it with official ics and have new baseband ?
Everyone thinks that unknown baseband means corrupted efs but not always. First try taking out your battery for 3 min and pit it back. Your baseband may come back. Works for me.

i wouldn´t reccomend to do anything like efs or whatever without having some basic experience
Just update your phone and see what happens. 2.3.4 isn´t the best firmware imo
i think an update is a solution for your problem.

[Q] SGS3-i9300 IMEI new issue IMEI 0049xx

Hi everyone
i swear that i read like 100 diferents threads about imei issues and i can't fix mi problem...
i had a Samsung Galaxy S3 i9300, the normal one, not the verizon, sprint or at&t.
accidentally i deleted or format some files of the phone that are really important by an option that i founded on the "RECOVERY MODE".
Ussually i only format de "DATA/FACTORY RESET" and the "CACHE PARTITION" but i have an other option that i click on it.... even when i was alerted about the risks.
So when i reboot the phone i couldn't get any access to the network and my imei was "004999010640000 / 01"...
i didn't have any backup of mi EFS file and i have another SGS3-i9300 so i back up the EFS folder of the working SGS3 and i rewrite de EFS folder of the bricked one.
Resuming i lost any chance of recover the IMEI from de .nv_data.bak file or any kind of this options....
I need to know if there's any way to fix this issue....
like write the original imei on any file of the EFS folder cause i have al the numbers but i don't know where to write them....
or any another idea...
Thanks any way:good::good::good:
Sending it to Samsung is probably the only option now
Flash a stock rom, and try again. If it doesn't work run the ariza patch.

I'm speaking entirely from ignorance but did you flash the right variant? E.g did you flash 925F firmware on a 925F device? If I were to hazard a guess (and that's all this is, a guess) I'd say your radio firmware seems messed up (with baseband also being unknown).
What happens when you revert to your original firmware?

Did you flash the 5.1.1 version and then the 5.0.2? Flash the 5.1.1 again.
Ok so i flashed official firmware,i now have signal but my imei number isnt right it reads as follows 350000000000006 it ses i am not registered on network. Imei sv is 01

Sent from my SM-G925F using XDA Free mobile app
Only way to flash it back would be if you made a backup of the EFS partition when you first rooted/installed recovery. The EFS partition contains all the IMEI data which is unique to your phone and flashed at the factory. Since you corrupted it, the only way to restore it would be to flash the EFS backup if you made it or send it back to Samsung for service. AFAIK there isn't a way to recover lost IMEI's if the EFS partition has been corrupted/wiped.

Yeah. I suggest sending it back for repairs and when you receive the new one, root and do a backup of the EFS partition after root. There are several guides online on how to do a backup of EFS using adb/terminal emulator. Keep this backup in a safe location and don't lose it.
You can flash what you want now, nothing will help you. Your EFS partition is gone and without this specific backup you cannot restore the IMEI number. Send the phone to Samsung, they can generate the IMEI number and restore the entire phone.
new trwp recovery have a option to backup.. will post the thread here as little warning in the twrp thread..
Yep I always backup my efs/imei folder as soon as I root phone.

Hi.
I did the same stupid thing a while ago with the same result (without efs backup). Forget about reflashing. The phone is now a mediaplayer.
I asked our local Samsung repair shop, but they wanted to exchange the entire motherboard. Thats how they fix these things in Sweden.
BUT there is an easy way to fix it.
If you have been flashing 5.11, then I dont know, but if you havent, then you can contact an IMEI fix website, and they will help you
by remote service. It works perfectly well. You will get a new IMEI and new serial number. Send me a PM for a link. There is not so many
people doing this, and it took me a while to find the right guy, but guess if I was happy when it was fixed
It will cost you some dollars (60 in my case), and you cannot upgrade to 5.11 later (I dont know why), but thats better than brick.
Hope this helps.

Is that actually legal? I'd send it to Sammy and get it properly fixed, rather than putting up with some dubious services. What if you want to sell the phone later? Have fun explaining why updating to 5.1.1 won't work. I wouldn't ever buy a phone if I heard that someone changed the IMEI. Changing the IMEI is usually associated with a stolen device.
I had the same problem (but IMEI dissapeared), when I flashed 5.0.2 didn't work. But Then flashed 5.1.1 and it worked. Try this. You will loose root.
