Lost imei number and device number

My phone was bricked and I restored it following this tut ( http://forum.xda-developers.com/showpost.php?p=62405939&postcount=138 ). Now the phone is turned on normally, but I have this strange thing:
My phone number
Unknown
IMEI
0
IMEI SV
00
I have also this warning: Current version is not available for user. Can't find matched cust for NT-code mcc/mnc, subset.
How to fix?

Same thing happened to me after I unbricked my device using the exact same tutorial. However, even with IMEI 0 I can still make and receive calls and text messages. But I'm not sure if I should leave my device like this. If someone has any solution to provide I would be very grateful! I hope it doesn't involve flashing any ROM again cause I'm really afraid that I may brick my phone again ...

Hey guys, I had exactly the same problem. I tried different things including flashing various Roms and Bootstack, but nothing seemed to work. Since I’ve been searching for a solution quite a while, I now have the honor to help you out and everyone with an L90, who stumbles upon the same issue.
First of all, I made a backup of my EFS, so that I could restore the state my phone was in (IMEI=0, but working baseband). You can do that easily with TWRP (thx to shoxxy . By the way, this is something which we all should have done beforehand. It would have been much easier to restore our IMEIs.
But don’t worry, if you follow the instructions in this video (https://www.youtube.com/watch?v=nwzgs1Cmr9k) you should be able to get your IMEI working again. For those, who feel more comfortable following written instructions I copied the following procedure using this thread (http://forum.xda-developers.com/showthread.php?t=1960918) as a model and edited them a little to the way it just worked for me.
Do this on your own responsibility! And better double-check with the video our other threads.
Before you start:
Download this package (http://www.mediafire.com/download/figdbxb75j5kyry/package.rar), it belongs to the user who made the video on youtube (PremiumRepair).
Make sure your phone is rooted and USB-Debugging is enabled (http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951)
Procedure :
Install Drivers. Either you use LG Support Tool or download them directly. For me the LGUnitedMobileDriver+3.14.1_ML_WHQL.exe worked just fine. Don’t forget to uninstall old drivers or you could run into problems.
Install QPST v2.7.378. Microsoft Visual C++ 2005 Redistributable is a prerequisite, just confirm it.
Plug your device into your PC (USB port)
Run QPST Configuration from your Windows Start menu. Switch to the second tab ("Ports") and choose "Add new port" (bottom left button). You should see a COM port associated with "USB/QD Diagnostic". Select it, then press Ok. You can close the QPST Configuration window now.
Open Windows Explorer and browse to "C:\Program Files\Qualcomm\QPST\bin" (or wherever you installed QPST) and launch RF_NV_Manager.exe. In RF NV Manager, Go to "Settings / Comport". You should see your COM port in the dropdown box. Select it, then press OK.
Go to "File" and choose "Read from phone". RF NV Manager will read all NV items from the phone. Now if you see item #550, you will be able to alter it (see below). If you can’t find it, go to “File” and choose “Read supported RF NV Items”. If you still can't find it, there is a way to create it. Take a look at the thread I linked to.
Now comes the critical step of altering the IMEI. Select item #550 and you'll see 9 boxes on the right, a "Write NV" button and an "Hex" checkbox. Check the "Hex" checkbox.
Now, you'll have to enter the IMEI in the 9 boxes in a very specific way. The easiest way is to use the IMEI converter (for other method see linked thread). Put your IMEI in, convert it and put the digits in the boxes (two number per box).
Now you can then press "Write NV" to write the IMEI value to your phone.
Once done, unplug the device, and reboot it. Now you IMEI should be changed. If it’s not your number, take a look at the step seven again and check the video.
Please give a feedback, if it worked for you (incl. Details about your device, ROM, etc.) so that other users can profit from it. Thanks
Edit: @ BlackStorm94 - Don't worry about the warning. It will vanish if you install a different ROM.

I'm stuck at step 6. When I click Read From Phone, I get an error which says that my phone is not present. Also, on QPST Configuration, even tho I have set the Port to the one my phone appears, under Phone it says No Phone ... I guess my phone isn't recognized for some reason. Do I need to root it before I do this? I hope not because I don't really want to mess with it after the hard brick

Yes, your phone needs to be rooted. This solution for rooting works great for me: http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951

So, I rooted the phone successfully, but the phone is still not recognized by QPST Configuration or RF NV Manager. My pc recognizes the phone and I can do everything properly, but these programs say that there is No Phone ... I don't know what to do ...

mhh, that sounds like a problem with the drivers. Did you uninstall all the drivers (incl. Qualcomm drivers) from your PC? And have you installed the official LG drivers for our devices (for example from the link in this post: http://forum.xda-developers.com/showpost.php?p=62405939&postcount=138) Try another PC if it still doesn't work

I'm going to try on a new computer tomorrow afternoon and I'll let you know how it went. I uninstalled all drivers associated with my phone on my computer and after reinstalling them I still got no results. I guess I may have confused it So that's why I'll try on a new one. Thanks for your help

Hello, sorry for the late reply. I just wanted you to know that even though I tried with another computer, my phone was still not recognizable. It doesn't really matter tho, cause even with the IMEI 0 I still have service and it works normaly for about a month now. If you have any solution then I would like to try it, but if not then it's okay. Thanks for your time

No worries! You do have USB-Debugging enabled, have you!? I mean you probably needed to do this for rooting. But if you haven't done it yet, that's probably the problem. Enable USB-Debugging like this (Go to Settings > General > About phone > Software information, tap Build number seven times and then go to Settings > Developer options and turn on Usb debugging) (copied from http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951)

Yeah yeah, I had USB Debugging enabled every time I plugged my phone into both of my PCs. But I don't think that's the reason this tutorial isn't working on my phone. When I unbricked the device, I had to use the L90 D405 loader.img in order to reflash the bootloader and recovery. But my phone is the d405n model, and that's the ROM I installed to it. So the phone now thinks that it is the D405 but the ROM I have installed is the one for d405n. I hope you understood this cause I know it's a bit weird I see options to activate NFC but I never use it so I can't tell you if it works. However I can activate it properly. Anyway, about the IMEI, as I told you, it basically works without problems even with 0 because I think that my service provider doesn't block anybody except someone reports the device as stolen. If you have any further solutions then let me know but if not the don't worry, I'm okay!

Ah, that makes sense. Flashing the right bootstack as described here (http://forum.xda-developers.com/lg-l90/development/bootstack-kk-l-l90-t3118632) could maybe help you (I haven't tried the one for D405n myself but it's supposed to stable). On the other hand: You probably installed a .kdz (ROM) with the correct Bootstack for your D405n included. ...So I don't think it'll bring back the IMEI or change anything. I'm running out of ideas, sry!

It's okay I don't want to bother you any further. I'll buy a new phone soon anyways and since I'll give this one to my small brother, I don't think he'll really worry if his IMEI is 0 If at some point this device gets blocked by a service provider then I'll start searching for ways to fix it again. That bootstack page you mentioned seems useful. I'll try that if I do have any problems. Thank you very much for your help

That sounds reasonable! You are really welcome If you still need help just post here again. Although I have no other ideas at the moment someone else might. If you felt supported here I'd really appreciate the thanks! button. Yeah, you are right, the bootstacks supplied by Xemidra are of great value for our LG L90.

Update: I actually fixed it I know I told you that I would leave it as it is for now, but today I had nothing to do, so I decided to try my best and fix it. What I did was, as the post you told me said, I had to install the Kit Kat bootstack and the easiest way to do that is by flashing the Kit Kat rom. So I downgraded to android 4.4.2 using the stock rom I found on another post, and then I used your tutorial on the Kit Kat version. This time I was able to pass step 6 because my phone was getting recognized properly. I also didn't needed root access after all, since the new rom was just installed and it worked. After finishing the tutorial and restarting the phone, my IMEI was back! Then I upgrated my phone to the lollipop version, and when the upgrade finished, my IMEI was still there. So now I'm in lollipop with a working IMEI. I'm so thankful to you now, thank you very much for helping me and providing me these useful tutorials. I really appreciate it

Wow, that's just great!=) congratulations, you can be proud! Happy for you, that was quite an issue. You are welcome=) Well, someone from this forum helped me out, when I seeked for help and I am happy to give something back. Thank you for sharing your solution! That should be helpful for the next one stumbling over this problem. Enjoy your completely restored phone!=)

Need to permanently change mac address

A few months ago I lost my k3 note but found it again recently. In between I bought another exactly the same (from the same source in Hong Kong) so now I have two. I'd like to give the spare phone to my wife but both phones have exactly the same mac address so can't connect to our home router at the same time.
I've tried a few apps which claim to change/spoof the mac address but they don't seem to work and anyway a temporary change is not ideal. Both phones are rooted and have twrp recovery and the same custom rom.
Help and suggestions would be welcome.

try sn writer tool.

Thanks for that help. I had a look at the process and it looks straightforward. The tutorial says "you need to have the database file of the same device on which you are going to flash the IMEI". It does not include any links to the sources of that database. So I am searching for the database but so far nothing I've downloaded has led to success.
Also have tried a different application, 'IMEI&SN Writer' but that too needs database to work.

Thanks that helped a lot. Ive tried several times but this is as far as I get
"Start searching kernel com port and handshake"
Phone switches on and boots as normal
"Enter AP Meta Mode: Meta Result = Default - Fail"
I should have said that the phone is rooted and a custom rom (K3_NOTE_MM_6.0_1611_3.54.1_v17_ROW_D-CUOCO92) is installed. Would that be the cause of failure?

Restored a backup of my wife's K3 note into my own. Pretty bad Idea. Now I have same MACs, same IMEIs, even flashing other ROMs.
Followed your instructions from your post but always got stuck at :

WiFi Problem

Hi everyone.
Yesterday WiFi stopped working on my Mi Mix 18K. When I try to turn WiFi on the switch immediately goes off again. It was working fine and the connection started to slow down. I turned WiFi off to use 4G for a while, thinking it was a problem with the AP or the ISP. A few minutes later I wasn't able to turn WiFi on again.
The MAC Address shown in the config screen is 02:00:00:00:00:00 and any change I try to make on the config is discarded as soon as I close de WiFi config screen.
It looks like the system were not able to communicate with the WiFi module. I tried a factory reset and flashed the original chinese rom (developer and stable) downloaded from miui site using XiaomiFlash tool (in fastboot mode).
Everything goes perfect except WiFi still doesn't want to tunr on. Maybe my wifi module just broke. Mobile data works fine too.
Any advice before my I start lying on the floor, crying in sorrow?
Thanks to everybody.

Same problem and no slolution..
Hello, I have the same problem after flashing custom ROM without saving ESF file of my beloved MI MIX... I been searching for a fix for a while now and as you can see nobody has a good answer for it...

Flashing a custom ROM shouldn't cause anything like that, unless you have incompatible firmware. I mean like which ROM did you flash, what are you on now?

I know but this problem is not new.. other phones have that issue as well and there have been fixes.Nobody can help with MI MIX thou... I can flash any new Rom by Epic Team with no problems but this is not helping with a lack of working MAC address... MAC Address: 02:00:00:00:00:00
No Bluetooth and wifi make this phone a half ass device.
My bet I did not save EFS file during the first flash with a new Rom.

O dear but I have never saved mine in 10 years. So you tried flashing the original chinese rom with miflash, might relock boot loader but as it stands its not really a phone,

I know i made a mistake of erasing everything including ESF file with TWRP before installing a new rom
I did not try flashing the original Chinese rom with miflash.. but must try this eventually.
Of course, re locking bootloader will cause new problems since it was not mine when it was unlocked.

Why do i have to sell it ? Cant, i reopen bootloader after it works? What if it does not work and i will end up with an unusable phone.
Bottom line.. i need to find a way to reload a mac adress into a phone with a right wlan.bin file... maybe somebody can send me in priv such so i can see what is the difference please between mine and working one.

It would be just as usable as it is now, sure I read warnings about using a different efs file, like total brick. If it was that easy I would send you mine, other phones have fixed by flashing the Chinese ROMs, just don't know with the mix. Chinese ROM us very usable if you use English or Chinese language.

I do use the English language so there is no problem .. and since there is no other solution I can think of I will do that... reflash Chinese Rom with MiFlash : )
Thank You in advance i hope it works

Hi James, nothing is easy with Mi Mix , MiFlash is not recognizing my phone so before I will install Chinese rom must solve this problem first... I do have ADB drivers, windows 10 signing drivers off... still Mi Flash is blind Which version would be the best? First Chinese stable Rom ? Returning phone to the original state would be the best but isn't Wlan Mac Address build into a hardware of the device? So how changing Roms helps this issue Just thinking out loud.

Yes I did.. I need this phone for couple of days so in the meantime I will read and educate myself first.. I am reading that lineage rom has fixed similar issues..
I couldn't believe how many people have that same issue without a good write-up or fixes available..
I looks difficult that's why. Even XDA is too short for this one.

Sometimes you just have to use a different pc , if it's recognised by the pc you need to see Qualcomm in device manager then miflash should recognise take a look:

SM-G800F no network, changed IMEI

Hello XDAs,
After reading that Forum with much enthusiasm for a few...well...years, i got my first question.
I hope you can help me with a big problem on my g800f: I can´t register in network.
When I search for network it pops up a few results, but if choose one to register, it says "Can´t register. Try again later."
I did a few hours of research and found out it might have something to do with my IMEI (Note: till that day i did nothing to my phone, except cf-autoroot. But never faced any problems!).
So I checked my IMEI and it wasnt the original, it was changed to 350695200123951. So I googled a bit and realised it might have something to do with the efs-partition. Googled for solutions.
Found out it might help to flash a Stock-Rom, one with three parts, via odin so i did it. Everything worked fine, but my IMEI still was the different one.
I was a bit irritated so i searched for that IMEI. And there are a few threads (some in russian and arabian), also owners of a g800f, which also reported this problem: They did nothing, but sudddenly the IMEI changed to this number. One author tells he received a myserious call from the ukraine after this happened. He didnt answer it. I am quite sure i also received that call- I didnt answer it either.
So i googled even mre: "How to restore a damaged efs-partition, without backup?" I came to one very outdated guide which wanted me to delete the efs (after saving it on externalSD) and do a few mysetrious actions...
Well, i just realised i cant fully delete the efs, its not possible and i also cant apply my backup from external sd. Anyone knowing a solution for this?
But, the most important, how can i bring my g800f back into mobile network?
Or just: How can i get away from that cursed IMEI?
Any Ideas?
P.S. If you got any questions regarding technical details of my phone(CSC, AP, Kernel, Modems), just ask. I´ll answer.
P.P.S I´m excusing for that horrible english. I googled the entire night and i´m german.

P.S. If you got any questions regarding technical details of my phone(CSC, AP, Kernel, Modems), just ask. I´ll answer.
P.P.S I´m excusing for that horrible english. I googled the entire night and i´m german.

I´ve just seen this problem being reported i a different thread. Guess the problem will be discussed there?

Hi All,
Did any one actually get a fix for this issue as I have exactly the same problem, my SM-G800F IMEI now also shows as - IMEI 350695200123951-01 which is for a blacklisted NOKIA 6310. If anyone can supply an absolute beginners guide for me as to how I can get my original Imei back that would be fantastic.
I am just a user of an android phone and have zilch experience of tinkering with them.
I have seen reference to things like Odin and flashing firmware and am quite happy to give it a go myself and learn
I will post this on a few other threads that list the same issue as I am desperate to get this fixed now as is a waste of a perfectly good phone !!
Cheers.

SM-G800F, can't register in network
Hello,
I have exactly the same problem. Since some month I got the message "can´t register in network". After checking all, I found that my SM-G800F IMEI has changed to a NOKIA 6300 IMEI.
If anyone knows a fix for this issue (set back to the orignal IMEI) , it would be great. All apps which I could find didn't work (XPOSED IMEI Changer Pro , Mobile Uncle Tools App, MTK Technikmodus... ), are not supporting S5mini.
I don't have a backup of the original system EFS file.
Would be great when one could help.
Regards
Chris

@S5miniChris somewhere in XDA I read that restoring the original stock (multiple part) firmware might or did help.
Gotta do it in Odin (recommended to use an older version like 3.09).

Thanks for your reply.
I have installed the original stock firmware. But it did not change the IMEI. Available for my model is only the single file " G800FXXU1CRG3_G800FDBT1CRE1_G800FXXU1CRG3_HOME.tar.md5"
Multible file firmware I couldn't find.
A manual modification of the IMEI should be possible with " Best smart Tolls " e.g. : BSTPRO 4.03 . But for the software a dongle is requiered. To purchase this is for one time use too expensive for me

Where from did you get the stock?
Samfirm_reborn tool already tried?
https://github.com/ivanmeler/SamFirm_Reborn/releases
Checking "binary nature" or "factory mode" downloads a multiple part rom.
Edit:
Checked tool and it's working.

I flashed now also with " binary nature " firmware downloaded with SamFim. The IMEI is still the same, it hasn't changed to the orginal IMEI.
I really can't believe that a firmware update will flash the E2PROM where the IMEI is stored. Therfor the orginal IMEI must be stocked some where
in the phone and by flashing transfered to the E2PROM.

Lancelot IMEI issue

Hello there.
I've got another problem with my lancelot. I've managed to rooted it successfully and install waveos, however, I still got an issue with no gsm data. I've found out, that my imei is missing - after typing *#06# phone shows you only hex serial number. It also does not show anything in system page in options.
I've read something about and tried to put back original imei back from the sticker. However, hydratool cannot open mtk module - it opens and before it is even able to load itself fully, it forceclose with no errors in log (it is the only module that it cannot open, rest works fine XDn't) and rest of the "tools" are simply crap.
What can I do? I did not have imei even when rolled back to miui 12 (I though it might be the issue, but it is not).

Here is a nice full guide that searching it certainly took less than writing this post ==> done by VD171
Make sure to thank him if you successfully solve the issue.
On a side note: Learn how to search stuff, it will save a lot of time for you and others.

You are definitelly right. I simply spend whole day on this and got actually tired of looking stuff, that leads to paid solution. I've even though of manual editing corrupted parts of rom (nvram etc), have working nvram from other phone as a correct matrix to do so.
Hope it works, I'll try it tommorow.

To edit nvram partition you need to flash engineering ROM first.
Hydra tool works, but it only works on engineering ROM, like I just said. And it's actually one of the main tools to fix IMEI.
Also Hydra tool isn't paid, what are you talking about?

Hydra ain't paid? That's good to know. I've got problem starting it though, mtk exe forced close itself before it loaded itself with no errors in logs, so I gave it up. I'll not have time today to do anything here, but I'll try in the following days.
I just assumed that changing imei is paid, just like getting rid of simlock years away.
