Unfortunately,after I flashed back to official 4.2.2 and rooted my Nexus 4, I lost my IMEI and baseband became unknown.
So now my phone can't take a phone call but wifi function is OK.
How can I get back my IMEI? Someone had the same problem before? Can someone give me the solution or links?
By the way, my phone's boot time is too long. (open 4.2.2)
The battery is used so fast. Even I turned off my phone, 1 night it used about 40%, 95%->59%
Can someone tell me it's a hardware problem or software problem?
There is no way to restore the IMEI yourself. Many people have tried on their own without success. You'll have to contact Google or lg to fix it.
Anybody else can help me?

Try flashing the 4.2.2 baseband/radio
Or go back to KK to see will the IMEI return

even I tried all of other radios, all failed...
Flash KK, and hope it will work
Search around XDA and Google, i think there must have been someone who managed to restore their IMEI

Hello,
I have a sprint Samsung galaxy s4 L720, unrooted on stock 4.3 baseband version L720VPUAMDC, the problem is that now it shows baseband, software version and IMEI as unknown and also it has an X up in the coverage bars so im unable to make or receive calls. I've never tried to root it or to change it's software. also on few occasions the info about IMEI and baseband comes back and I can make calls again but it just goes back to unknown after a while. also I've tried to reinstall the software and made several factory resets. I just don't know what can I do anymore.
help will be appreciated
thanks.

Really an unrooted MDC firmware?!
You haven't been getting update notices for months and months?
How long have you had the phone?
Was/is it flashed to another carrier?
How did you 're-install' the software? PC Odin? What version of Odin?

I had the same problem. To fix it I just reflash the original rom that it has with Odin. Ex.: Mine is NAE 4.4.2, so I flashed that with Odin PC.

*The only update I got was the 4.3 one.
*I have like 4 months with the phone.
*Yeah it is flashed to another carrier, I'm in a foreign country. it worked smoothly the first 2 months and a half.
*it wasn't me who re-installed the software. I had some cellphone repair shop do it.
hope this helps.
Take it back to them to fix it.

The problem is that it had the issue before they reinstalled the software they just couldn't fix it and they didn't even charge me, so I don't believe it's their fault. also I noticed that I have baseband version L720PUAMDC and Build number JSS.15.L720VPUEMK2. shouldn't these 2 be the same?

No they don't have to.
What they probably did is keep the baseband at MDC because that (or MDL) is needed for doing SIM/Carrier unlock and flashing. And they updated the ROM to a MK2 build.
Obviously they screwed the pooch somewhere.
Your best bet is reading through the few SIM unlock posts here in the forum (there are already a few and have dozens if not hundres of posts!). And using google to maybe look into your specific country/region/carrier flashing options.
Uh oh...

If you update everything via MK2 you'll get everything back...except I'm pretty sure you'll lose the unlock, unless you know how to bring your baseband back to MDC...pretty straight forward, just Odin the modem.
So basically:
1) Odin MK2 full
2) Odin MDC modem
You should have your baseband back and thus everything restored.
This will not affect your 0011 menu edits.
In worst case scenario I will do this pro bono...you just take care of the shipping fees, but you should honestly try, at the very least, the above 2 steps.
before you do anything extreme, go to mobile network settings and set your cdma subscription to nv.

Hi, so basically I flashed a Jelly Bean ROM (4.3) over my KitKat ROM (4.4.2) and have since
permanently lost my signal. I've tried flashing a multitude of Modems and ROMs, yet I'm still unable to
obtain signal. My device shows emergency signal bars but that's it. When I go to assign my carrier, it comes up with some of
the major carriers here in the UK (including 3, which is my carrier) but my phone always fails to connect
and register on the network. I'm faced with the same problem when I select 'Select Automatically.'
I've been told that my problem lies with a corrupt EFS folder, but my IMEI still shows as it should (The same one on
the back of my phone.) I've tried using a different sim card but still the problem persists. When I booted up with a
different 3 sim one time, for a split second my carrier on the lock screen had changed from
'Emergency Calls Only' to '3', but changed back to the former immediately after. I'm yet to try and use a sim from a
different carrier. Any suggestions?
You cant downgrade android 4.4.2 to android 4.3 coz they use different bootloaders. You will have to flash again android 4.4.2 for recover the signal and solve ur problems :highfive:
Reflash kitkat 4.4.2 as u can not downgrade from 4.4.2 to 4.3.
Maybe the IMEI Certificate is damaged, and need repair, try *#0011#, if at the end of the list you see IMEI CERTI: FAIL then you have to take your device for repair, if show PASS then try the latest modem

I've tried flashing 4.4.2 ROMs through recovery but no progress. I've tried flashing the
official 4.4.2 ROM through Odin but still it doesn't work. Also, in Service Mode,
IMEI Certi shows as NA :/ does that mean I'd have to get it repaired?
Yep, take the phone to a repair shop, is the only way out, i say because i fix that a lot on my shop

Damn didn't want to have to get it fixed :/ do you (or anyone else for that matter) happen to know how much a repair would cost?
well on my repair shop, the cost to the client is 50$ for EFS v1 and 60$ for EFS v2, and now you have EFS v2, the cost in different country is not the same as you know, so ask for the repair prices

I "killed my phone for more than 4 hours a couple of nights ago. Long story short I was trying to do the same thing, "downgrade fro kitkat for personal reasons. The phone wouldn't boot up, and couldn't get it to go to download mode. Afternseveral tries it finally got into doenload mode and I was able to reflash with original/official kitkat, and it works just fine, the onky thing is that I keep seeing that imei certi : na status on the service mode screen and can't navigate to other screens within service mode. Im trying to sim unlock it using that method. I'm not sure that I did anything special, just try to reflash again with official kitkat and hopefully it will stick...
Wen i dial *#06# my imei is fine but Wen i dail *#0011* i also get imei /na my phone doesn't have any signal also I don't know what caused the problem cause i got the phone second hand also on 4.4 2 stock, could this be the problem y I can't get any signal at all? I also tried flashing custom roms and stock kk ROM but still no signal help please
Hi everyone, I have a huge problem in my hands and wanted some guidance from you guys.
Recently I bought the GT-I9505 in the US and then I moved back to Brazil, once I got here I got an update OTA from 4.2.2 to 4.
After this update my network signal was gone , then after some research I found out that my IMEI number is lost. When I dia *#06# it appears that the IMEI is Null. My question is , is there any way of fixing it or is my phone gone forever? If I send it to mobile phone service is it possible that they fix it?
Thanks in advance guys... This forum is incredibly helpful

Before giving an answer we're going to need a little more information. What steps did he do prior to losing his IMEI, did he flash a custom rom, custom radio, or did it just magically vanish?

so i got baseband and IMEI null too (i read that is normal when you lost EFS)
i was using it without make calls but it is boring because i have to use another phone to calls. and it's boring. i forgoten it in the bag and when i see battery has gone
recently until my mac adress on rr nougat change to another (i read that it's normal but i don't know)

hi, sorry my bad english too... I had 2 z6, one with this problem and another works normally, i get this when update from ota (not unlocked yet), in the middle of process of update my phone reboot and get a much time to appear the first screen, when finnaly shows my networks is gone. I made everything and i discovery something in my research. When they (Asus) release the first and official unlock method of bootloader, in the package comes the all softwares to access direcly and update the modem and backup the keys (from baseband). i made everything right in my 1st zf6 but my HD failed and i lost everything, and the method of unlocked has changed so i think the only solution is contact direcly Asus or buy a new board. I sent for repair directly in Asusbr and they said to buy a new board and simply trow me back without answer if is possible rewrite the baseband. :crying:
This method of repair modem exist ! but only for zf5 and i try and not work maybe for you work

One time I installed a custom rom which deleted my IMEI. So all I did was to flash a zip from another custom rom that I know worked from TWRP and it got back.
If you want an alternative to installing another rom, find your IMEI from the zenfone 5 box ( if you still have it) and paste it on an IMEI changer app <--- look for it on play store. But I don't have any ideia if this method will work as I have never tried it.
