NV file needed and method to fix 'no simcard' problem !! - Optimus One, P500, V Q&A, Help & Troubleshooting

Hi,
I recently got my phone in a major problem while installing recovery using LGMDP. Right after that 'no sim card inserted' is flashing constantly flashing on my screen and I am not able to use my 'phone'. i had a backup of my phone's NV file. I tried to restore it using this and this but couldn't for dunno what reason. In frustration I later deleted all my files saved to fix this problem including my backed up NV file. Now before going to LG service centre to fix my phone, I want to make a final try to fix it myself.
Please help I need a NV file and definite method to restore it in my phone.
Thank You.
Please dont be mad at me for posting this 2nd time on different section.

still no solution
i need help from the experts

you have to take the phone to the samsung service center and get it repaired because your efs folder is missing which has the imei number

With a phone root and busybox
Galaxy unlocker > https://play.google.com/store/apps/details?id=com.helroz.galaxysunlock&hl=fr
Trying to see if you can recover EFS

i tried those you've mention but no luck, i wanna try to restore a nandroid backup but i don't know where can i get or is there will be someone to lend me his nandroid back. sorry for my bad english

there is NO IMEI because your efs folder is corrupted or missing/doesnt exist/got deleted,etc..so here are the things you need to follow
* Root your phone first using this link.
http://forum.xda-developers.com/showthread.php?t=1894737
*Flash a custom recovery (ClockworkMod Recovery/CWM)
so now you have a custom recovery so now you can take a backup and you should take a backup(for precautionary measures).
*Install the app "Galaxy_S Unlock" from playstore as LoLaTion said and if you cant download it from playstore then download the apk(installation)file which you will get easily on web.
Also install BusyBox which is available on both playstore and web.
*Now by using the application "Galaxy_S Unlock" try to recover your IMEI.
and if still there is no luck on your phone then you can just go to Samsung Service Centre and hopefully they will solve this problem for you.:angel:

Phone=rooted
flash cwm for backup
installed busy box
tried to repair using galaxy s unlock
but no luck, service centre said they can change board but it cost 70-80% of the brandnew
i can still see my efs folder
.nv_core.bak
.nv_core.bak.md5
.nv_data.bak
.nv_data.bak.md5
was dated 10/12/2012
and my friend said this phone was damage in november
i think there is still a way to fix this rather than go to service centre cause i still don't have budget to buy new board

do you get any error message like
Warning! A problem was detected with your device. Your device IMEI number is invalid. And invalid IMEI number could cause network issues including the inability to call emergency numbers.
then this link might help you http://android.stackexchange.com/questions/28963/how-to-restore-my-imei
however,while browsing our forums I came across this http://forum.xda-developers.com/showthread.php?t=1308546
but you cannot use it because its not for our phone... wish we could had something like that.. and just asking out of curosity does your phone have a IMEI number under the battery?

you said you can see your efs folder... try this http://android.stackexchange.com/questions/28963/how-to-restore-my-imei
since you can see your efs maybe somehow on CM9 or CM10 there is a possibility that your IMEI can be restored.. give it a try
GoodLuck

Strange efs/imei problem, wont flash to stock

so I have a SR I just put a new (used, off ebay but new to me) motherboard in, and it works fine except for no imei/baseband, so obviously no data/voice/etc.
the efs folder seems to be fine...imei folder is in there, keystr file is there...I don't understand what the problem is.
the worst part is, only certain roms will flash...I cannot flash to stock, I've tried with odin and from recovery, a couple different stock versions of GB, ICS, and still no luck. It actually flashes, then does the "android is upgrading" screen, but then bootloops on the optimizing apps part. I've tried to flash to stock probably 20 times now, wiped everything, fixed permissions, etc...without fail it bootloops every time.
the only roms Ive gotten to flash are slim and jedi...no stock rom will flash, nor avatar and a couple others I've tried. but slim and jedi flash and boot right up...just have blank imei/baseband.
I've scoured threads for days trying to figure out what to do here...nobody seems to have my exact problem, and everything I've found about restoring efs/imei/baseband has involved flashing to stock...which I can't do.
anyone have any ideas?

Have you tried flashing different radios (baseband)?

Take a look at this thread, it may help. http://forum.xda-developers.com/showthread.php?p=25172599#post25172599

thanks for the replies...
I've flashed UCM1 and UCLL3 radios, they flash fine but no change...still can't flash to stock and no imei/baseband/service.
That fix thread was one of the first I found, but as I still have my keystr file in the efs folder, I didn't think it would apply to me...I suppose I could make an external backup of my efs, delete it and try one of those methods from scratch.

read through the restore to stock sticky http://forum.xda-developers.com/showthread.php?t=1652398 and go through the trouble shooting sections, if that doesn't help u could have bad hw

Hey, Im facing the exact same problem! just that my imei turned to 0 and basband to unknown after i upgraded to cynogenmod 10.1-rc.2.
It was working fine till suddenly one day i lost network. I tried everything like you did. So far ive had no luck fixing my efs!
What you can do is download QTPS and in it there is a RF NV Item manager to rewrite your efs. For that you need to put you phone into DIAG mode unfortuantely i cant get to that on 10.1nightly cynogenmod that im using.
I m stuck. I know for sure flashing roms or radios wont help at all. the same boot loop problem happens when I flash using odin, it use to work perfectly fine earlier.
Some how the nv_data.bin and such files are missing from my efs>imei folder that contain the imei data.
If you find something please lemme know too [email protected]

will do.
also, you may know this already, but just in case, be aware the skyrocket doesn't use nv_data.bin...I thought it did too when I first started searching around about this, and when i couldnt find it I was pretty freaked out...but then i found out the skyrocket actually uses 3 encrypted partitions rather than a nv_data file. so if you have at least some files in your efs/imei folder you may be in a better spot than it seems. of course if its totally empty, you'll likely have a lot more work to do.
I'll update if I have any luck.

Yes I have two files in my imei folder i,e keystr and mps_code.dat!
I tired changing them from root explorer! pasted someones else's efs folder! but still I cant fix my imei is stays 0.
i donno how to get to diag mode with this rom, otherwise i could have tried my luck with QPTS.

Incase you have broken your imei without backing it up, there is another way. And yes it is legal.
Here's the tutorial http://goo.gl/wtW29 and here's the needed tools (software & hardware) http://goo.gl/54mtk.

I actually have octopus box as well as the z3x samsung tool installed, however, they're both server activation based...the software is useless without an $89 (octopus) to $120( (z3x) activation.
I'd rather not spend that kind of money for something I'll likely only need once, so I'm gonna do as much as I can in the way of free solutions, and if I have no luck there I'll probably just send it to mobiletechvideos for their $40 efs/imei repair. I'm guessing they use one or more of these repair box programs themselves anyway, and will do the same job for only $40.
thanks for the suggestion anyway though..

There's this polish guy who probably also has all the same boxes and he takes €10 for imei repair by remote desktop.
http://forum.samdroid.net/f70/repair-imei-s2-5729/
And finally you could try helping the op of this thread to add compatibility for skyrocket, this would be free.

Isn't there any way to fix my imei on my own ?
Mt efs folder also looks good now with all the files it should have but still the imei remains unaffected.
Also i'd like to know that the qualcom nv tool showed my esn as dead and mied as 000....000 does the dead thing mean it isnt repairable ?
I tried using QPTS but this is where I get stuck.. (img attatched)

Obviously there is since some random polack can do it for you on his PC, the problem is the lack of knowledge.
Those who know won't tell you how, because they want € for it :crying:

People want money for it because it's mostly used for making stolen phones work again.
That means real life risks like fines, jail etc.
Of course there are lots of examples when people experiment with this or that and delete their imei accidentally, or want to change the imei for some other reason. But these are more rare.

An update...
I managed to finally get flashed to stock...still null/null imei & baseband unknown. Efs folder is still there with files, keystr file is on...not sure what else I can do myself at this point so, I guess its time for the Polish dude or mobiletechvideos.

unfortunately not for me. I finally got the polish dude to try restoring the imei remotely...he used like 3 or 4 different programs, nothing worked.
so, i just got a broken SR with a cracked lcd off ebay for $50 and used the motherboard from it.

Ohkies.
Did you ask the polish guy about the reason why he was not able to fix your mobile. Coz, I'm just having similar problem like yours. I tried working with all the local samsung service centre guys, nothing worked. One guy said that my mobile IMEI is locked in some database, so it is not picking or detecting my SIM, hence locked. I know that my mobile is unlocked and is valid, I ignored his comments.
I assume you changed your MotherBoard of the mobile with the new cracked SR's, so that it could take new IMEI instilled in new board. Is it so?
Also, please suggest me about any alternatives on how to fix this problem.:crying:

Bricked S6 please help

Hi guys
recently bought a s6 from ebay which was frozen on S6 logo. Basically managed to clear cache and factory reset from recovery but that didn't work, anyway I DL the O2 firmware and odin and put it into download mode I get a fail on odin when trying to install the rom
The phone has knox 1 and also has red writing SW Rev. Check Fail. Device: 3 Binary: 1.
I'm unsure what to do and if theres any chance for me to recover.
Many thanks
Mav

it failed because you flashed an incompatible Firmware.
where did it stopped flashing in odin? In sboot.bin?
If thats the case, you need to download proper firmware/country for your device.
Let me know what country is ur fone made of.

Hi thanks for your reply.
I managed to get it working by installing root and unikernel, it boots into O2 the firmwarw is 5.1.1
Only problem now is imei is 3500000000006
And it wont make calls dont know if imei is corrupt ir they sold me a stolen or lost phone?
I may install tw recovery and custom rom and see if that works.
Any suggestions?

Hi
Ive managed to sort out and get it to work infact typing on it now. Its currently rooted custom rom and twrp. I e managed also to restore original imei number so overall im quite pleased with myslef lol.
Anyway one last problem i have is ive tried all sims but none work i know ita picking up signal as the bar shows top right. Also chexk my settings.
Ive tried automatically and manually going to register networks but it says unable to connect try again later. I know uts not my area as my wifes s6 works perfectly. Sim also def works. The phone also picks up when a new sim has been inserted so i dont think its sim slot.
Any ideas guys

OK new update if anyone can help I'd really appreciate.
Installed new vador rom Imei reverted back and serial number is all zeros
Is this something to do with baseband if so how can I fix read somewhere about ariza patch but that was s3 4 etc.
Thanks
Mav

1. Your EFS is corrupted. The IMEI you see is a generic one, phone will be useless for network provider only wifi will work.
2. The one thing that caused this is by flashing an old bootloader to your phone. Thats why youve encountered Check Fail error on Download mode.
Happened to me also but got it fixed in the end.

OK thanks for the info how do I fix? I do have my wife's s6 but that's not rooted and don't want to root can I restore the efs
Many thanks

I think I know one thread that has a firmware downloader with ultra fast download speed you may try searching it.
I dont know if it will help, but you may be able to successfully flash the firmware but many of those who have problems were unable to boot the phone due to corrupted efs data.
Here's my way of fixing it (if you still have intact efs). http://forum.xda-developers.com/showpost.php?p=63693480&postcount=28
But if its already wiped, there's no way you can retrieve it unless bringing it to samsung or any repair shop.
Anyways, mine was fixed (IMEI) using Octopus box repair tool. Since I cant do anything to recover my generic imei.

As far as i know if your EFS partition is corrupt and you do not have a back up of the EFS partition to restore which you probably dont as you bought this as broken then sim capability is dead, im not sure of any other way to fix this unless you have the intact efs partition

Hi
How can I tell if the efs is corrupt it shows a baseband it now shows the correct ime I
It just won't connect to network it says try again.
I can post a screen print of efs folder on es Explorer if anyone knows what it should look like

Here are screen prints but I think I'm speaking to myself lol

Hi there i spent months on fixing issues like this (i now have a tool that takes care of all this) , best thing you can do is flash to a rom where the original imei came back do a backup of the efs, flash to a orginal rom ( latest rom) make sure its the right one for your device, connect to kies, install the rom again root and restore the efs failing that the imei is blocked use checkmend.com the uk version if your from the uk, message me if you need help

Your rom, recovery and kernel doesnt have to do with corrupted efs.
Only way is to bring it to repair service using box tools to re enter/validate your imei so that you can connect to your network provider. There is no other way around other than retrieving your efs and installing it or thru repair service.
You may now relax yourself at finding ways to connect, I assure it wont help trying to flash and flash and flash stuff to your phone.

Uhm can you send sms or make calls? It seems you have a valid Imei

Ok ive tried all stock roms including o2 and a uk btu one but no luck they all do the same thing get frozen on Samsung logo then I flash unikernel and it boots.
When checking my efs folder I can see no modem file I'm now wondering could that be the fault? so I downloaded modem and BL for 5.02 and 5.11 both will not flash via odin I get a fail message and on device check fail device: 3 binary: 1 messgage in red?????.
So I'm a little lost, I was wondering if I managed to root my wifes s6 which is virtually new could I back up her efs folder then copy it into mine and just amend the imei to my original would that work? also is there a way of rooting my wifes phone without triggering knox?
Any other suggestions guys I really don't know what bootloader was on it to start with or rom is there any way for me to find this out?, also another weird thing when the o2 uk roms install they install german apps?
Thanks guys

Ive repaired EFS Partitions with scripts downloaded from links at xda.
For example i trashed my EFS partition on my note 3 so it caused hard reboots after android booted up and it couldnt be fixed with anything else than the EFS partition repair scripts.
Edit: friend repaired his Note 4 also.

Thanks but where can I find these scripts as I've looked everywhere and if I did find how do I go about doing it. At the moment when I try to flash modem and bootloader it fails.

Radio off, QCN Backup?, Modem corrupt? - Help me please

Hi guys,
I have no signal, and my radio is off. I figure my QCN or Modem was corrupted during a factory reset, as it happened after a factory reset. I am on the indian ROM ZUI 2.0.111 ST.
So either my modem is corrupt or my QCN is corrupt or both, could someone backup theirs and give me a copy QCN so i can fix mine and flash it to my phone. and or provide me with a modem file and instructions to flash it only.
Instructions for backing up your QCN are in my thread on ZukFans.eu here this is a good idea even if you don't feel like helping me out.
I have already tried flashing stock roms
2.1.059ST_root_xposed flashing with TWRP
ZUI_2.0.069_ST with QPST & MiFlash
ZUI_2.0.093_ST with QPST & MiFlash
But none of that helped so either my modem is fine or those ROMs do not contain a modem, i'm not sure how to tell.
If you can help at all, if i am doing the wrong things to fix it or could try something else please tell me, I've been trying for days to fix this and i really need to get my radio working again so i can call and what not.

Note 5 from hell! Nothing brings back the signal / IMEI / Baseband

i tried to unlock the note 5 i have using nv_data.bin without making a backup of my efs. got all the way through installing twrp, custom darkstar rom, and more. When i went to finally put a working sim card in it.... NO SIGNAL/BASEBAND UNKNOWN/IMEI UNKNOWN! i tried everything, from using smart switch, to odin.... Whole firmware flashing, to just modem.bin & sboot.bin (and others individually) for a while seperately it wouldn't work with a full firmware restore (using odin or z3x it would stop at cm.bin) but eventually i got it flashed and back to stock with odin & z3x on N920TUVU4DPK6 latest firmware, even used smart switch to flash to stock, but NOTHING brings back the imei or baseband. even tried to use xposed to change imei with app when it was showing up missing. efs backup pro didnt work as it couldnt read pit for some reason but odin could read pit just fine. z3x wont reset efs, wont repair, wont repair certificate, wont unlock. even the efs backup pro apk wont fix the problem.
Im all out of options... i am very knowledgeable about technology in general, and i have been rooting/flashing/tinkering with android phones for 4-5 years now (working with computers and tech for 15 years). Im stumped on this one... anyone who has some extensive knowledge in this department willing to connect with a team viewer session and try to help me out or at least post somethings to try.
I really need help BAD and am lost without guidance... i also can't afford to buy a new phone so im hoping this can work again soon. before i did anything it was working fine, only locked to t-mobile so i dont think its a hardware issue.
anyone out there got a heart (and brain lol) to help! :crying:

Do you have efs backup ? If you have made efs backup i can help you. If you don't have efs backup then i suggest you go to any repair center cuz odin or custom recovery not gonna do the job.
To restore efs/imei you will require a dongle box to write new cert files in efs partition.

i have z3x and have been trying to re-werite a cert i found online but it didnt seem to do the job, and i dont have a backup, the backup i do have was after it stopped working :/

Kies or Samsung switch
Have you tried using the restore on either Kies or Samsung

Hey happened to me with the note 4. There is a guy on ebay I used and he repaired/restored imei remotely. Cost was 60 or 70 bucks. Took all of 10 mins. And phone was even unlocked afterwards. Might be with a shot.

I have the EXACT SAME problem that you have. I'm on the latest firmware N920TTMB4DPH2, I can't rollback to prior firmware. z3x couldn't detect my phone's modem, I've been looking for a solution too. In my case, someone told me (even z3x log said the same thing) that I have to downgrade the phone's modem, but I still couldn't find a way to do this. I think in my case, I have to wait for Samsung tool Pro to finally support the modem or find a way to downgrade the modem. (Can't even find any modem out there). I just tried Samsung tool Pro 27.4 today, still doesn't work. I think you might have seen this post? This might help?

what! add me on the list, i was searching the same problem, and i found this thread. i guess no one can help in this community with no backup efs file. my device is sm-n920t note 5. i can downgrade to lollipop by, from stock nougat i will root and flash custom firmware, then on the custom firmware i flash it to any stock rom. this doesn't solve the problem.

Haha same issue here... A year later... And still no solutions... Mine is SM-N920P. I accidentally rebuilt the nv_data.bin file and my unlocked phone is showing me that my SIM card is invalid. I'm busting my nuts to find a solution.
