I've made a search, and i didn´t find anything about this:
Anytime we install a new rom the imei changes, I'm i correct?
Anyway to go back to old imei? The imei changes and the programs with serials don't answer anymore. I can't ask for new serials anytime i make some changes. The sellers are already saying i'm crazy!!!
Is that possible to keep the same Imei every time we change rom.
Thank you. Help will be apreciated

I believe that mun_rus rom holds the IMEI
the IMEI does not change, the last 2 digits which indicate the firmware revision change... these are NOT part of the physical IMEI

How do you explain, everytime a change rom, the program tells me it's not registered? I have to ask for new serials to access the program.
What can i do to avoid that?

Are you certain that the programs are using the IMEI as the key for the serial number check?
In my experience most Windows Mobile programs use the device name as the key - as they are usually designed to run on phone and non-phone devices (which don't have a IMEI).
So after you re-install the program try changing the device name to the same as it was previously and then enter your original serial number.

Thank you antzzz. I'll try that
which program?
some programs use the user name or the device ID itself.
The device ID can change according to the ROM.
I have fist hand experience with this in TomTom Traffic - flashing every WM6 ROM except mUn's TE changed the device ID from the original WM5 one.

any chance to avoid that? Or restore the previous ID?
no- the device ID is set by the ROM and some iteraction with the phone.
You have to go back to a ROM with the same ID. For Me mUns TE for WM6 had the same Device ID as WM5 which came with the phone.
All other WM6 ROMs give another device ID (and I heard that some give a new ID randomly after hard reset! Awful bug.
how does one read their device id so i could know if it changed after a flash?

Why do you need to back them up? They don't change with a custom ROM

I didn't know, I've been worried that is like on Galaxy S I9000, if you put a custom ROM is likely that the IMEI to be changed. THX for info.
Oxid0,
Are you serious about the Galaxy changing IMEI ? If so that's scary. Great way to hide though.

WOW.
I thought that the IMEI was "burned" into the phone and not reconfigurable on a whim by software changes.
As I said Scary.. I'll make sure when I get my next Android phone to not be an early adopter on ROM changes just in case....
i am using an HTC HD7 prior to running the mango update i was running everything stock... my phone was chevron unlocked but everything else stock..
After the update i am unable to use the live services..
marketplace / xbox live . i get the error code 800488FB which i believe it means your account has been blocked.. and it does ask me for my username and password right before the error
i get no error but the facebook chat does not appear to work either..
i used the provision.exe method for updating to mango..
yes i am using the correct username and password..
everyone said make sure you save the backup from provision.exe where does it place the backup at? it disnt ask me to save anything and i cant find any trace of a backup?

your problem may have nothing to do with mango. check here. it is a locked account message due to suspicious activity. Follow the instructions in the link and you should get it back. As for the backup, people reported that with the first version of the non-MS tool they ended up with 4kb of a restore point as well, basically losing their backup. I suggest to always make a backup of your WP restore point yourself. the backup the tool created should be on your C-drive called PreMangoState
Hi All,
I had purchased T-Mobile Samsung Galaxy S4 (SGH-M919) with Stock android 4.3 while I was in usa, and want to use it in my home country now as I have left usa. I couldn't found any unlock solution on internet for stock android 4.3, and T-Mobile would not give me the unlock code. I tried third party services to provide unlock code and it did not work either. So I went to a local shop, and he screwed everything up. When I went back to the local shop to receive my phone (hoping it might have been definitely unlocked by them), he told me that he tried to downgrade it to 4.2.2 but it did not work (only after reading through all the forums I realize there is no way to go back to stock 4.2.2 if you are on stock 4.3 because of knox / bootloader issues on 4.3, leads me to think the shopowner did not really do his research before touching my phone, and no, he did not do any EFS backup). In an attempt to unlock my phone, he also flashed Metro PCS stock ROM on my phone, not to mention, my IMEI number is also 'Unknown' now. I managed to get back on T-Mobile stock 4.3 ROM now but still IMEI is unknown. I also tried to go to nearest Samsung center and they said they would not touch international phone models. At this point I have no idea what to do. Any suggestions how to get back my IMEI and or at the least to get the phone working to my country's network?
Thanks.
Try flashing the mk2 modem using odin. That may work but not sure.

The local shop broke it. Tell them to pay for it.
Also, the only reason T Mobile won't give you an unlock code is if the phone isn't paid for in full. If the phone is paid for in full, they HAVE to give you the unlock code.
Are you sure you didn't buy the phone in the US, then leave the country without paying the bill so you could use the phone internationally without paying full price? If not, there is no reason T Mobile wouldn't give you the unlock code. So there's some missing information in this story.
Also, we do not discuss how to change IMEI's on XDA. The only thing permissable on XDA about flashing IMEI's is restoring YOUR OWN IMEI from a backup. That is done by restoring the EFS partition. But you didn't have a back up so you can't do that. That means anyway to fix your IMEI involves what is an illegal hack and that discussion is expressly not permitted on XDA. That information is used for illegal purposes and XDA is not going to be the place where it's shared for legal reasons.

Hi skipjacks, thanks for responding. Nothing is pending with t-mobile, I was on prepaid account. I bought the phone like 10 days before leaving usa (due to emergency). T-mobile says my number on this new device should have being working for at least 45 days or so with refill balance. My cycle ended after 15 days of purchase and I really didnt see any reason to refill it as I was no more in usa. And no, I dont want to CHANGE my IMEI, only want to restore my own IMEI only. I am not sure if my EFS partition is corrupted, because I rooted my phone tried to backup EFS folder now (I know its too late but still), deleted it and rebooted (as a few threads suggested it would regenerate nv data files), but neither did I see any nv files when I did a back up now, nor after I rebooted. When I rebooted, the EFS folder did regenerate but there were no nv files in there. Also, after deleting EFS and regeneration the serial number was corrupted, but when I restored my backup, the serial number showed up correctly again. Also my current backup contains the imei folder with mps.code_bat file. I noticed that even imei folder was not regenerated on deletion of EFS and reboot. I somehow have the feeling that this is still indicating that my original EFS folder is still present (though I may be wrong, because I dont know). But my concern is the nv data files, which I dont see anywhere. I did come across several threads about imei corruption and restoration, but the only one I didnt come across was T-mobile SGH-M919 with stock android 4.3. I am wondering if this has some different file storage structure for imei (which again I dont know). At this point I am concerned about getting back my imei, I can get the unlock code from some reputed paid service again. I understand that open discussion about imei involving anything CHANGING IMEI is not allowed here. If anyone could just help me out restoring my original imei, even by pm, I would really appreciate it. I just dont want to throw away the phone and lose my money because of the error done by repair shop.

First off....the enter key is your friend. Hit it every so often when typing giant blocks of text like that. :laugh:
Second, since your IMEI has been deleted, you now have to change it, even if you just want to change it back to what it was before. The process to fix it now is what can't be discussed here.
IF you had backed up your EFS partition, then it would be as simple as restoring it in recovery. That's all well and good. But your IMEI is now 0, so you have to change it to what it was.
But all that aside, you went to a store and they broke it. Take it back there and raise holy hell until they fix it for you or buy you a new one. I know consumer protections are stronger in some countries than others, but wherever you are, yelling and screaming is a universal language.

Can someone at least tell me what file in T-Mobile Galaxy S4 SGH-M919 Stock Android 4.3 contains imei number, so at least I know if I even have that file or not or whether it is missing? Thanks.

Whether your file is missing, modified, or corrupted, you need your /efs folder to restore it. You do not have have a nandroid backup or the /efs folder. I am sorry but the simplest we can put it without sounding harsh, you're screwed. You need to request the local shop give you a replacement phone or credit to get a new one.
Update: I went back to the shop and told them "You broke it, you fix it, I don't know how and I don't care, you gotta fix it". They managed to fix the imei number somehow. Regarding unlock, the shop ended buying the unlock code themselves. They mentioned that no one is able to unlock T-Mobile S4 with Stock 4.3 as of now without unlock code, unless they have some device like Z3x box. The phone is finally unlocked and working fine on my network. (YES, A HUGE HUGE RELIEF).
Everything is fine, except for 2 issues.
1. I want to backup my EFS folder so that I don't enter into trouble with IMEI again. I tried EFS Pro, but its not working. All I see is "'Initializing ADB server..." (the phone is rooted, usb debugging mode enabled, and supersu permission granted when prompted). I also tried to backup using Andromizer, but it says "Notification: File not found in /storage/emulated/0/Amdromizer/efs/efs.img". What is my best option as of now to backup and store my imei safely somewhere?
2. I am having issues with Wi-Fi. Before the shop flashed my phone, it was all good, but now it doesn't auto-connect to my home Wi-Fi anymore. Everytime I reboot or get out of range, I have to manually select my home network everytime and also enter the password everytime. Nothing has changed on my router. The other Samsung device that I have still auto-connects to my home Wi-Fi as usual. How can I fix this?
Thanks.

For the efs you can back it up using recovery. Just boot to recovery and its one of the options in the backup menu. The resulting file will be like a few KB. Its supposed to be small. Dont worry

I am new in this Forum and i had flash a costum rom and i didn't backup my EFS FOLDER (I KNOW THAT AFTER MONTHS !)
IS THERE A WAY TO RECOVER IT
Flash back to the stock rom you were using before he custom rom. The imei may have disappeared because the bootloader and modem on your are too old for the custom rom you installed.
thanks for help but...
Thanks a lot for help i read a lots of threads and i didn't find a solution for this when i tap *06# my imei is correct it is the same in the back of the phone but when i try to check my balance i can't and the phone show ''unable to process request'' or '' invalid mmi code'' and i can't do any operaion with *----# i could only check my imei with *06# so what to do ???
Can you check your balance on the stock rom?
i didn't try it
I didnt try it till now i didn't back to stock
Since you have the imei back, is there a problem other than checking your balance?
yes i can't do any operation starting with * end by # i can't even execute any of secret code like *#1234#...
Same thing happens on a stock rom? These operations may need a stock dialler.
i don't know i will try it thanks any way
Any luck correcting the problem?
