Hello,
I've been looking around for a solution for this issue.
My friend tried to root him phone, and I have no idea what he did... now his baseband is gone... Baseband version unknown.
I tried to install a new xxpe and then ddlf2 still no connection.
I'll get him to JellyBam A4 same as my phone. is there any file(s) I can copy from my phone to his to make it alive again?
his IMEI from *#06# is blank.
Any ideas?
Thanks in advance
try this method..

since IMEI is blank, i think the only solution there is to go to service center and let them repair it..but, if u have backup the EFS folder which contains the important files then there's a 99% u can use the phone..flashing on different ROM wont make the problem to be solve since IMEI is blank, just like my phone with no IMEI, now it is just like IPOD touch..hehe
Well he didn't back anything up.. lol
What if I took my working EFS file from my phone to his, will that work?
will he get the same IMEI as me?
can I mod the file(s) to his number, which I have from under the battery slot?

you're thinking is good that you want to ask for his EFS but sadly it is not possible coz IMEI is a unique identifier for every phone just like a PRODUCT KEYS to every computer, if that detected that 2 IMEI was using, one will be blocked..that's what i think..
if we can mod IMEI then i think no one will be having problem if in case there's IMEI has been lost..right?

well, I know it is unique, and I do have his original IMEI.
and as far as I read it can be restored in case you already made a EFS backup.
so my phone has a working IMEI files... same phone, only diff numbers.. they have to be encrypted at some level, and we are talking about android here, probably not encrypted.. I Don't know.
guess it is a long shot... but maybe I can alter my numbers to his...
IMEI and product serial number, all the data is written under the battery slot.
I'm no developer just thinking out loud... lol, maybe someone can light up the way for me, if my idea makes any sense on any level.

wrong understanding..hehe i have 1 phone and becoz of my laziness flashing some ROMS my IMEI has been corrupted and never been use for a months, and after how many days, weeks or months searching and reading here at xda for an answer, i found out and tried that we can use fake IMEI which starts at 0049xxxx and flashed it, now i can use my phone now with fake IMEI and i am happy with that eventhough it is not the orignal one..now i am thinking what will be the risk if we use the fake IMEI and asking here at xda..i open new thread, hoping for someone will explain it to me.

care to share how to set up phone with the fake IMEI?
would be grateful..
I was helping a friend to unlock his phone, and I accidentally delete nv_data.bin and dont have a backup. I know the original imei, is therea way to regenerate the imei? If I dont have backup. Please if somebody know i need help
Try one clicking back to stock
ok, i will download in my house, but, i was reading that one clicking dont touch the efs partition, and that file was there
Was the phone on gingerbread or ICS/JB? If it wasn't on gingerbread (Assuming it was a rom not based on CM7) you'll be able to restore the files by using a one click
the rom is in 2.2.1. Thats ok? I download T959VUVKJ6_STOCK-UVKJ6-One-Click.
So, if I use it, this will restore the nv_data.bin? I ask before doing anything because i have fear of make the this worse

Yes it will. Keep in mind that it will also factory reset your phone
I do it and gave me a imei thats only 000000000000000.
I insert the sim and work, But, this will give problems in the future?

No it won't. lol The OP is already on a BML partition structure. That trick only works if you loose it switching over to MTD.
Sorry OP your IMEI is gone and short of some fancy hex editing their is no way to get it back. Your phone will still work with zeros but data might be an issue. If you wanna try the hex edit way look in the dev thread for OLD unlock threads. Good luck.
So, i will have issue with 3g data or something like that?
I see a way that i can input the imei with a z3x box i think, and in my city there is someone with that box, that can work?
i search and only found: ;
REF] How to unlock SGS 4G or Vibrant 4G (IMEI Problems fixed)[Updated 11-19-11]
[Carrier Unlock] SGS4G AROMA Unlocker
I search in the dev forum. Do you remember something more about that post to search? :/
Hey all,
Ive been flashing things since early HTC Hero days and never had this issue before. I flashed a new kernel (Uber nightly if that matters) the other day and the IMEI is now 0, no network signal, cannot connect to services, random reboots, etc. Tried completely clean flash stock rom using guide at beginning of general thread running bat file (by windows), still nothing. The file seems to be corrupt until I can reenter the numbers so device recognizes and can get network. Went completely back to stock yet still have unlocked bootloader. Tried looking over the internet for some solutions, only found Octoplus IMEI repair but do not know if I need the box or not in order for it to work. Any alternatives or if anyone knows if the software works without having to buy the box. Want to avoid sending back to Google or LG. Links and suggestions are appreciated.
EDIT: no previous backup had been made to the file.
Did you backup your imei?

No, didnt previously make the backup of the file. I know it exists on the phone back and other places Ive seen but I need to inject that number back into system files so the phone recognizes it again. I didnt know of this issue before this but I wont be making this mistake again.
This probably won't help you after the fact, but I'll link this thread right here http://forum.xda-developers.com/google-nexus-5/development/modem-nexus-5-flashable-modems-efs-t2514095 and check the EFS Backup section.
You basically have to figure out a way to manually input the IMEI back into the EFS Somehow, the thread I linked might point you in the right direction.
{Mod edit: Quoted post has been deleted}
Do you know how to get the tool to recognize the device, etc on how to use it. I downloaded demo to look into this yet no luck thus far on how or where device is to write to. I have drivers ,ADB, etc installed.
{Mod edit: Quoted post has been deleted}
Even after reading, still no idea on how the program recognizes the Nexus. Still blank unless you know how

For now I would keep trying re-flashing factory images again, this time using the long method 2.
I have had this issue. It happened to me on November when I got the phone and wiped cahe. I fixed just Reformating cache on twrp and flashing a CM Rom. It returned my IMEI

try flashing a new bootloader for the device. i take no responsibility for what happens to your device after you flashed the new bootloader.
But wasn't changing imei illegal?

It is illegal to change it for another one. but the issue Op has is something about recovering his own withing allowed parameters.

Sadly, no. The imei number file is specific to the phone and to get it "injected" was considered illegal since people who steal the phone could, by theory, inject the new imei to sell a phone as new. There is things out there (sort of) on this yet nothing good can be done. I use TWRP now since the back up allows EFS folder as well, versus CWM that didn't. I haven't had the problem since on nexus 6 or lg g3. The only way I know how to "solve" it was warranty through Google for nexus 5, they sent a new one to me and took the bad one. Only they (the manufacturers LG and Google) can legally inject the phone back to working condition. In all, had to get new one because no real true fix out there (legally) since even recovering it may be an attempt at stealing, the manufacturers cannot distinguish one person from another. Wish I had better news. Hope that helps and you can get it resolved.
There is an app on*******. IT'S ILLEGAL TO CHANGE A PHONES IMEI NUMBER!!
You can't take a number of am old phone and put it on a new, even if you have both. I can't see its wrong to put the original number back though. I've started a thread and asked the powers that be to rule on giving out the apps name, etc.
Sorry if I revived this post...
I know how you feel.
If you message me I will send you a link to a blog I wrote on this subject, I didn't think it was possible to fix but you can.
I know it's illegal. But google supports custom roms and rooting. So they must understand that this can happen.
Uhhh, I think all of you are incorrect. You may want to check your facts or your phones. If you have the manufacturer's firmware, in my case it is a Xiaomi Redmi Note 10 5G, you can use the manufacturer's (or other) method to flash the firmware and the IMEI numbers will be reinstalled. I was required to login to their site, but that's why you should register electronics with the manufacturer when you purchase them. It might not even need a registered product. And, after I was able to recover the lost IMEI numbers, I noticed that I can freely change them if I desire. Soooo, maybe I'm breaking the law? I suppose that would all depend on my location because this phone is mine, I bought it, rooted it, put a custom ROM on it, then did the dumb a$$ move of arbitrarily deleting files that "just didn't look right". One of those was a key component. Keep in mind, possession is 9/10th of the law. I possess this phone so no matter what, they can only charge me with 10% of a crime.
After multiple flashing of ROMs and kernels, suddenly my baseband has gone (Unknown) and IMEI too . After reading multiple forums, I figured out that it might be a corrupted EFS and my phone is not under warranty everything works fine...wifi, bluetooth etc...only no cellular signal...please help guys already flashed factory images (KK and Lollipop) and tried few custom roms....but same problem Was on latest optipop with Code blue r793 :crying:
Thanks in Advance
Fastboot flash stock cache.img usually fixes this. Not seen many EFS issues on nexus 5. Mainly Samsung has this problem

Afraid not mate . Messing with the EFS is illegal in some countries - and there's not much we can do anyway. The only ones who can help you are the guys at LG - keep pestering them until they agree to rewrite your efs.
Why did you not flash your own number. It's on the box and inside the back cover of the phone. To use a friends is stupid and illegal. You can't have two phones with the same number. It's highly illegal.
2G Only
Well, Managed to get back my IMEI as one of the local repair guys injected it...donno how bust maybe using Octoplus Box....But now stuck with 2G only as if I try to switch to 3G/4G, it does not work and phone reboots. Tried multiple roms, LG Flash tool...no resort....any help wud be highly appreciated

Interesting. He just used an IMEI switcher app then? Check and make sure your APNs are correct. That could cause loss of 4g but shouldn't ever cause the phone to reboot.

I checked my APNs and am using the same ones I had earlier. Reboot does not happen if I fix my connection to 2g...anyways, I read on XDA that flashing back my QCN file of any other D821 using QPST might solve this..I also have a file which this person shared. (QCN does not hold IMEI info but only NV backup). Can someone guide me whether this will work and if yes, how do I do it?

You may have to use the tools capable of flashing stuff to swap CDMA carriers to get AA passwords n stuff back. And its illegal to swap ESN/imei in some countries but i don't see harm in repairing what u broke as long as info is original to Device

From here:
http://thomas.loc.gov/cgi-bin/query/z?c112:S.3186.IS:
That bill didn't pass but one like it did. I can't find it right now but you get the idea. FCC regs also allow for REPAIRING of it.
XDA however won't really allow any talk of how to do that because in some countries it is illegal. Plus they gotta cover their arse. So I'll just leave it it that.
No tampering with IMEI here
Thanks for the replies. But I am at all not wanting to tamper with my Imei.. Infact the imei is stable and fixed... I just want my 3g back... Rest of the phone is working perfectly fine
First things first, I'm sorry for opening another thread on this but I feel the other ones weren't headed exactly in the correct direction.
A little background:
I was trying to downgrade my XT1541 to Lollipop since 6.0 was really bad and I got frustrated and used
Code:
fastboot erase all
The result was I erased my IMEI and I haven't been able to connect to a network carrier since. The problem can be solved by re-writing my IMEI but that's the difficult part.
What I gathered so far is I can use QPST, backup QCN, go into HEX and change IMEI there, then restore the QCN back to my device. The problem is I can't locate the IMEI in my QCN since my IMEI is now simply 0.
So in all, could someone make a backup of THEIR QCN and send it to me? I would flash it to my XT1541, locate the IMEI (since now I would know what I'm looking for), then change it back to my own.
Does that sound like something that could work? Can anyone help?
UPDATE1: Noone sent me their QCN however I did try to restore the one I backup up (which still has an IMEI=0). QPST Software Download reports
Received an invalid command from the phone.

So getting another QCN won't help as it seems that I can't write the IMEI (qcn) back to the device...
There are only two possibilities of fixing this... a 50/50 chance that a full factory flash will restore it (don't know how, but it does sometimes). If that doesn't work, then you need to send it to Moto for repair.

Well, unfortunately that leaves option 2... or turn it into a media play and buy a new phone.
Funny how `fastboot erase all` causes such a pain for some and not others... but once your IMEI is gone, there isn't much you can do. Moto kinda screwed the pooch on that one.
