Hi everyone,
I just picked up a GS4G and want it to work with my Tmobile web2go account but am having some trouble. Some people simply delete the EFS folder but that doesnt work and I have been able to reset the IMEI to all 0's but that gives me problems too.
I have read some people that have a generic IMEI number (004999010640000) or something like that and was wondering how can I get that on my phone. From what I have seen, it is due to flashing a certain rom or messing with the nv_data file. So which rom can I flash to get a generic IMEI or anything else I can do?
Thanks for any help anyone can offer as I would really like to save a few bucks and keep my data plan as it is. Thanks again
the generic actually doesn't work. It won't give you service.
Ive been playing around with it but after 2 days, I am still able to make calls and connect to tmobiles 4g service with the all zero imei.
For anyone wondering, I first deleted the efs folder (dont recommend unless you have 2 backups), restarted and then it came back with a weird imei of weird characters. I was able to make calls but couldnt connect to 4g which is my primary reason of doing this. So I edited my original bin file with microsoft word and changed a few numbers around, replaced it into my efs folder, then got the all zeroes imei. Then I flashed it back to stock via odin and after this, is connected with my internet plan just fine and could make calls fine as well. I thought about leaving it like this but then flashed it with valhalla black edition and it still connects just fine with an all zero IMEI. I still would like to try it with a bin file that gives an IMEI of 004999010640000 but for now, it works for me just fine.
I pay $5 a month for data from Tmobile (Web2go/Tzones) and didnt want to upgrade and am glad I finally got it to work after a few hours of messing around. If anyone has any questions, let me know. I look forward to poking around the SGS4 threads for awhile until my next phone.
Hi mendezj666,
I just got my SGS4G today and I also have the $5 a month data plan from tmobile. Can you please share where to change on the nv_data.bin to do the trick? I appreciate that.
Thanks

Have you read up on this phone and know how to root and install roms and know how to use odin? (All very easy to do) I just dont want to get blamed if you mess up your phone and want to make sure you have at least two back ups of your nv_data.bin file (preferably on your computer as well as your sd card).
Also, just to make sure, it asks you to upgrade everytime you access the internet on 4g, right?

Thanks for the quick response. I use EFS_Pro_1.4.7 to backup and restore the efs folder. I just upgraded the phone to SMS-KJ6-beta2d_Stock-Rom_with_Bootloaders-One-Click. I do have two backups of EPS folder on my PC and my sd card. I also made a CWM backup.
Correct. It asks me to upgrade my data plan which I want to stick as long as I can. It works great on 3g on my rooted ICS HD2, but I want the 4G speed.

K, just want to make sure. You shouldnt have any concern of bricking your phone since you're just editing one file and can always replace it but as with all flashing, just doublecheck everything. Delete the entire efs folder on your phone (you may have already done this), restart and should have a weird imei number of characters. On one of your backuped efs folders, find the nav bin file and open it with a hex editor. Then I just changed around a few of the numbers in the first lines randomly and saved it. I might have used Microsoft word to edit the bin file but both should work. then i put that nav file in the efs folder on my phone and rebooted it and put it back to stock via odin. Then when it restarted it still had the IMEI of all zeroes but could connect just fine on 4g.
This worked for me and hopefully works for me. If not, I MIGHT be willing to send you my own nav bin file that I personally use (which I wish I had at the start since it would have been much easier from the start) as long as you arent in my city. But thats a big risk since it might make my 4g stop working which would really suck
Thanks mendezj666. Please check your PM. Thanks.

i have a Galaxy Nexus, i have this generic IMEi number for my phone 004999010640000 i changed using a root app called doCOMO or something...i changed it frim my normal one so i could unlock the phone to any network after rooting. Now it has locked me out of every network! Is there anyway way to change it back? i really need help on this im a noob!!! please help me
thanks

This is the galaxy s4g forum. You might post your problem in the nexus forums. I have the bin file for the sgs4 that gives a working imei and works on tzones.
Well, it seems like I have "No service" on my phone, and it says that my IMEI number is 0, and my IMEI/SV is 01. I tried flashing stock rom onto this when it happened. I can't afford a new one and the only way I can keep this phone is if I can fix it - is there any way I can make an IMEI then find the folder to put this back into my phone? I have no backup, but I do have a folder called GSII_repair and it has 2 files, efs_save.tar and efs_save.tar.gz, but I'm not sure it is of any use. I just recognized the efs as the efs folder. I can't find where my IMEI is at the moment, either, so I don't know whether it is completely deleted or just corrupted. I also have a Moto G 3rd gen, I may be able to get an IMEI file from that, and then change the hexadecimals to fit my phone's original IMEI which is on my box. So please tell me, am I completely runined, and my phone is destroyed, or is there a chance that I can fix it? Thanks for any replies. Guys please help me though, I need it!

Hi,
I have a note 3 neo, 7505 and i updated the firmware. It was all working good for a week then i was listening to soundcloud to sleep and the phone restarted, since then the phone doesn't have an imei and says to insert sim card, and of course unknown modem..
Anyway, i created a backup of the efs using twrp, i have tried gazillion ways to restore the backup and gazillion manual ways too. Going to stock recovery... trying to copy manually the nvdata and all but it doesnt resolve. The files are placed there, i can see it in the shell but the thing just wont work!
i don't know how to proceed to this, i don't know if its a hardware fault, had it been that, shouldnt have i gotten the efs corrupted or some issue? could it be that the hardware itself is damaged all of a sudden? i dont think so, i pretty much think its the efs and yet i cant restore it?
should i attach my efs folder if someone can look through hex editor or logs to suggest a possible solution?
Thanks a lot and also i have search through and proceeded with many solutions and after that created a thread. hope someone can help.
P.S. I just noticed the serial number can be seen in phone status, so apparently its reading NVdata? or is it getting it from elsewhere? how to test if its a hardware fault?

The point is that TWRP creates faulty EFS backups on many devices which can't be restored properly.
There are different backup solutions (e.g. EFS Pro) confirmed working which may help you prevent future issues. I prefer the manual backup using adb shell or terminal emulator:
dd if=/dev/block/mmcblk0pXX of=/storage/SdCard/efs.img bs=4096
(XX needs to be replaced with the model specific partition number as they use different partition tables)
Restore:
dd if=/storage/SdCard/efs.img of=/dev/block/mmcblk0pXX bs=4096
thanks LS.xd, but i guess i have a pretty solid backup as i did create backup various ways, some were corrupt, but one that i working with has nvdata and every other file along with imei pretty intact....
i can open it up with winrar, and open the nvdata with hexeditor, i was wondering if i could confirm some way that the back up is actually 100% solid?
wondering if the partition's aren't aligned. I don't know for sure if EFS folder in the root directory is the same as being pointed by /mmcblkp03/platform/by-name/EFS ?
i mean they should be the same thing, its just a redirection right?
what should i be doing now? the baseband is unknown and the imei wont just work, waste the phone? or it could be done via some boxes or some other process?
there must be a starting point? isn't there some way i could use a generic imei and just any modem? then i could replace nvdata may be? right now, i'm installing various versions of stock firmware and repeatedly placing old efs data in various ways and i kind of turning hopeless. first i lost a nexus then i bought a g4 last month, gave me a bootloop just a week after, gone dead. then i bought the n3n and now this..... i mean 3 phones in a row..... i really hope this could work..

So you got some non TWRP made EFS backup, too? You can list your partitions using shell:
[email protected]:/ # cat /proc/emmc
You can use the dd command once you know the layout. Backups not generated manually may only be restored with the specific app/version and are probably not compatible using other restore methods. For my OnePlus 3 EFS backup can generated fine using TWRP but restoring it screws up the partition. Manually created image works fine. As I don't have a Note 3 Neo I don't know how it behaves for your device.
any idea how would i go on about inspecting the nvdata.bin? i'm in hex editor trying to see something resembling imei but its just so much garbage except a few lines.
i can't be sure whether its corrupt or not...
in efs -> imei -> a file called mps_code.dat i open it up in hex editor, and it has only 3 characters.....
is it possible i could initially use a generic imei and modem and later on populate it with actual somehow or just keep using generic one for now until i find a better solution, using hex editor or something...?
there are some tutorials on qualcom.. none for exynos but it should happen the same way, somewhere in nvdata, you place the imei ... and it would be generic method for most exynos devices...
i wish someone could guide me to that...
also can it be restored via "boxes"?

After 3 years I had to retire my HTC One S. I flashed roms and firmwares up to 3-4 times a week without having any issues. One sunny day some update bricked then nvdata. I spent a bunch of hours trying to restore it in different ways, extracted data from stock firmware as well as using dumps from other user's phones, as some users reported this error fixed doing so. Even when the files was identical it just did not work for me. Changing the mainboard was the only possible solution so I decided to get a new device.
All I want to say is try to restore a valid backup in a way confirmed working. If you don't have a usable backup ask in your device's forum for somebody may upload it. Or spend 100 hours messing around with hex editors until you reach then point where you realize its cheaper to switch the device as wasting a year's holidays browsing the internet for some solution.
Hey everyone!
I have a Teclast M30 (MTK6797) tablet.
I updated it to the latest firmware with the flashing tool, and lost my IMEI and SIM card capabilities.
No baseband, IMEIs are null.
Things I tried:
- Restore NVRAM, NVCFG and NVDATA with the flashing tool, after editing the scatter file to make them downloadable.
- Used TONS of tools, like various versions of MauiMETA, ModemMETA, SN Write Tool, R&W tool, and others.
- Use MDDB & APDB files from other/older FW versions.
- Relocking the bootloader, just for kicks.
- Generating MP0B_001 file and placing it into the directory mentioned in a post here.
- Obviously, different SIM cards, to eliminate the possibility.
- Using the technician code in the dialer. The relevant option is not listed in the Communications tab.
Any suggestion is welcomed. I really have no idea what to do at this point, especially considering that the tablet is being used constantly due to the quarantine, and ordered a SIM card to allow family members to communicate via video where there's no WiFi.
Thank you and best health!

Flash the stock firmware that you previously had on the device before you updated. It might restore your IMEI.
Other than that, as stated in the XDA forum rules, we can't help you retore your IMEI unless you made an IMEI backup before the issue started. You obviously didn't create an IMEI backup so we can't help you with restoring it.

Hey, thanks for replying.
The action I took was the update of the official firmware.
No, unfortunately I haven't backed up my IMEI partitions, not that even at this point - I know which partitions are these.
As I said, I have the number printed out on the box the device shipped in, therefore essentially I'm looking for help in restoring this partition.
I made several restores to the official firmware, new and old, but IMEI isn't being restored. Hoping there's an actual solution to this - we need this SIM for WhatsApp communication, keeping in touch with family at very restrictive times.

I understand your situation perfectly....
But...
That doesn't change anything about my reply.
As stated, the XDA rules only allow us to help with restoring from an IMEI backup. The reason for this is because anything that involves using a flashtool or other methods to rewrite your IMEI can be used, by others that might see it, for nefarious purposes, such as using the instructions that we might give as a means to change the IMEI on a stolen device or a blacklisted device in order to activate the device, which is illegal in a lot of places. Therefore, those kinds of discussions are not allowed here, regardless of your reason or your needs. This rule is in place to protect a potential user's privacy and device security.
Sorry, can't help you at all. Keep searching on your own in other places other than XDA.

I understand, obviously it's not the case here, but I wouldn't want to break any rules.
I haven't found a solution in days, before arriving here to ask. So, if someone sees it and has an idea, I would appreciate help, even with PMs.
The main purpose of utilizing a SIM card at all is whatsapp, it's not like we're going out in the near future.
Contacted Teclast's support, which explained that the IMEI partition was wiped, and the tablet has to be shipped back for a reflashing.
This is impossible as we're in quarantine, and we use the tablet daily. So... if there aren't any suggestions - guess we'll stay on WiFi, w/o WhatsApp.

It's in the GPRS settings.
Use the third (oldest) is best into
But as you said, it's on the box, so it's no biggie.
Set, reboot.
Anyone left with some humanity is requested to PLEASE HELP ME if you have a Redmi 6a device or know a guy with redmi 6a device.
I actually bricked my device unintentionally and did found a way to get out using SP Flash Tool, However the thing I am stuck in right now is worse than bricking a phone.
Both SIM Cards are not working. I did a lot of research and found that I need two files:
[nvdata.img] [nvram.bin]
Unfortunately I don't have any backup for this. Now what I am looking for is some kind hearted person who can take a backup of their [nvdata] [nvram] partition and give it to me and I'll replace all their data like IMEI numbers etc with my own. I have my IMEI numbers ready to be feeded. I did a lot of try using those engineering ROMS and Tools. NOTHING WORKS!
I regret my decision of jumping in something I don't know about. I want you to please have pity on me so that I don't have to live without my phone.

I tried it but it still shows imei unknown. What device is your fixed mobile phone? xiaomi or some other?
IMEI gets added to mobile device when it's built. It's stored in device's /EFS and/or /NVRAM partition. If you haven't backed up this partition before you flashed a new ROM then you have lost unless the IMEI is printed on the box in which device has been delivered.
