Hi!
I have problem with my lenovo p780 4gb Chinese version (after 04.2014)
I am using vibe ui 2.0 (row version from sympty's thread)
I flashed couple Roms to find my favourite and probably messed up with the nvram.
I was having problems with no signal, nvram error in WiFi ect.
I couldn't restore my imei (done with mobile uncle but after reset the problem apeard again).
Decided to recover nvram.img but as I did not have my own backup I used one uploaded by sympty. (Before restoring nvram made a backup of my own messed up nvram, just in case).
After recovering sumptys nvram the problem with imei and nvram error in wifi disappeard . I noticed that I have symptys imei so I overwritten it with my own using moboleincle.
The problem is that I still get the network problem. No signal at all. Tried many modems also the one that have been adviced to me here (the one created by xaep).
Do You know what can cause this?
I noticed that in mobile uncle radio information the signal is not floating. Once it worked it was floating now it is still and shows 0 db 99 and.
What else could I mess up and how can I fix it?
Thank You guys in advance.

So that means that I did not rewrite imie properly?
Also, I noticed that IMEI on the baterry is diffrent than IMEI on the back of the box. My phone have been in service in China, maybe they've made a mistake?

This is strange. At least one of the IMEI'S from the box must be the same with the IMEI from the accumulator. They could switch the box on the service store, i think?

Yes probably You're right.
Soo does it matter wchich imei I will use? The one on the box or the baterry one?
Also I am still facing the problem with network. Tried many modems. And now i eaven get the problem with sim card (mmi error).
I changed the nvram for the one i got from this forum.
Can't really rewrite imei with sn writer but managed to do it with mobile uncle. (It changes, but after factory reset it goes back to the imei i got when changed nvram).
I don't really know what else could that be. Maybe it is the rom?
I really like this phone, but I am starting to think of getting a new one without network problems.

Hi. It does not matter what IMEI you are running. It doe matter to have one .
With network problem it is the same! If you dont have IMEI you cannot acces any GSM network. You can change all the modems, if you dont have IMEI your phone cannot acces network.
And yesss.... MobileUncle Tool is an temporary solved problem.
I did not encounter this proble myself. I have saw this problem to others.
From what i have read i saw that this problem could be solved with an older firmware like s119, s123, s124. Dont know how but some of the users did write the IMEI for good.
You can change only the motherboard, or change all the phone and this one use it like power bank, nice agenda, or other uses.
Good Luck.

Will try to go back to the older firmware like You said.
Basically if it doesn't matter what imei I have, than it is not the imei problem, because I do have imei after factory reset, only it is probably Yours (because i restored nvram uploaded by You ;D).
In such a case, maybe the firmware will help.

Hello,
I have the Samsung Galaxy S II
Flashed with Dark litening rom.
Just today, this problem started. When I start up the phone I have signal for maye 5 minutes. Then I see coverage bars, but it says emergency calls only in the notification menu, and I cannot connect any calls.
I bought two of these off the same guy online about a month ago, the other one works fine so i think (hope) its not imei blocked.
I have googled it to no avail.
I have tried removing battery sim card and resetting.
I have tried a different sim card.
I have tried factory reset.
None of the above worked.
Please help.
Thanks in advance, any and all suggestions are appreciated
I checked the imei here:
http: //www . amta . org.au/?Page=405
And it says unblocked.
So it must be an error with the phone? Please help.
Thanks

Check your IMEI is the correct one that came with the phone and matches up under the battery ..
Probable you damaged EFS folder when flashing a rom .
Restore your backed up EFS folder .

Thanks for the reply, unfortunately I have checked that already and they are matching. Any other suggestions?
same Issue on my side
I try all what i can.
even another modems. No help...

Do a factory reset, wipe data and cache from CWM recovery if you have it, or flash a new rom. (Backup anything you dont want to lose).

Hi! i experienced this issue with my Samsung Galaxy S2 after flashing ICS rom. It's weird as well that when I transfer the sim to different phone and place it back again to my phone then it works but the moment I reboot my phone then I will get the same issue...
Same problem
Same problem right here about a month in to using CM7
Going round in circles...
I've now tried all sorts.
Wipe caches, factory reset, different kernels, different modems, new SIM card, battery & SIM out, reboot, chec ed if phone is barred, checked if IMEI has changed, all sorts....
Still no luck.
Can anyone help?
I found out what the problem is.
The same thing happened to me.
Emergency calls only, couldn't connect to a network, out of service state, IMEI was fine.
I went to the network operator that sold me the phone, and they scanned my phones barcode and told me the phone is blacklisted.
Go to your network operator and check if this is the case. I'm 99% sure that it will be. You ought to be able to unblacklist the phone

Sadly 99% of those with a problem have not a blacklisted IMEI they just broke the EFS and never bothered to read the fAQS and GUIDES .

IMEI is fine.
How to fix?????
And have you both asked your carrier if the phone is IMEI blocked & absolutely positively 100% ruled out a carrier side problem ? (Given a lot of these problems tend to be carrier side one way or another).

Hi
i was a happy customer with my SII, which i brought from india, everything was fine, until a week back, when suddenly my SII shows no signal, no IMEI and no baseband
i didnt flashed or changed anything ...
1. i tried using different SIM - no use
2. this sim works in other phones
3. factory reset - no use
4. all is done...
**** I DONT HAVE A EFS BACKUP ***********
please give me a detailed fix route for this issue. as i cannot take the phone to INDIA in next 4 months to get is repaired. i have my warranty still. but thought that something can be done from my side to get it fixed. please please lemme know how to fix this! :-(
I had this happen to me. I hadn't taken an efs backup and thought I was screwed, but I found an auto backup on my SD card called EFS_BACKUP. Check if you have this, if you do, use GSII_Repair from the market to restore it.

If your EFS is not total screwed and your nv_data backup is valid its possible GSII_Repair from market will work for you ...
Once you have tried all the guides and still in the same situation, check out this post
http://forum.xda-developers.com/showthread.php?t=1372169
I tried already flashing the Stock ROM once, and hence i dont know whether there is still a backup of EFS is in place....
can anyone take a little bit more time in explaining the steps to solve this,
like does a backup from another gSII will help the purpose... ?
please let me know more details, i will be thankfull like anything.
How come this problem happens, when we do a complete flash does the EFS folder get replaced or the the flash doesnot affect the EFS part at all?
i feel its very strange to see such kinda problem..
buying Z3x isnt a good idea
Z3x-box sa
msung - 169USD
Z3x-box LG - 169USD
Z3x-box 2in1 (sam+lg) - 299USD

what you call its as total screwed??
Will a backup from another Samsung Galaxy SII work ? for me?
EFS is a folder would be having NV_data and some other files. he's asking that the entire EFS got screwed or just some parts.?
I tried complete flash, means baseband,Kernel and system including User data reset.
i really confused about the relationship between the EFS folder and the IMEI,basband, blah blah...
EFS folder is nothing to with your blah blah nor your modem /baseband .
It is essential the details of the phone and its sole identity that is signified by the IMEI number individual to each phone . This IMEI number is used in the initial handshake each time you make a connection .
Lost or stolen phones can have their IMEI blocked once on the block list handshake is denied by the networks = no connection .

GSII_Repair tool from Market, Four steps in that tool, am Done ...........all is well now.
Really really helpful tool. Thanks to all who suggested this TOOL ;-)

u mean is that a nw problem? nothing to do with the phone?
its really p***d off me for fixing that issue..
handshaking happens only after the phone detects the sim card. but here phone doesnot detect the sim at all. so is ur point still valid?
my phone was brought from samsung authorized dealer so how come its possible to happen so?
looks like EFS is the area where full flash no longer having access to it!! if not then a complete flash should have sorted that out.
EFS are reference files containing the imei and phone unique info, when these files gets corrupted, then phone will b helpless.
though u have root access u'll never get RW permission inside the folder.
there should be a automatic recovery, the SW should have had in place if there are corruption. poor implementation.... bah...
Hey everyone!
I have a Samsung Galaxy S6 Edge G925F that will not connect to a cellular network and wont display my IMEI serial number or SIM Status.
I have tried everything:
Flashing Stock ROM with ODIN (Just get a fail)
Flashing multiple modems and AP's
Backing up and restoring my efs
The phone still boots and I have backups of my supposedly corrupted EFS
This happened after flashing a 5.1.1 rom in ODIN
My stock rom is: G925FXXS4DPIB
Nothing works. Please I need help and I dont have access to a Octopus box to re write my efs either, is there a way I can fix it.
When I put my phone into diagnostic phone with qualcomm's tools I just get a "Device has malfunctioned" error, I'm using Windows 10 64bit

Wow that's the most awful thing that can happen to you.. I had the same problem as you on a MTK device.... I don't know about this device. But I tried with a app that let's you rewrite the IMEI number.. but this didn't worked for me.. maybe it will work for you.. wait some other guys here will respond asap .. also check on YT about your problem. I am sure there you will find what are looking for.

The imei app your talking about only masks the imei number and doesn't permanently change it back to what it was. Thanks for trying to helping though
I've messed up my device after flashing using qpst. Now my imei is gone, fortunately i can still use my sim and access 3g network. Problem is i cant use 4g. I suspect its because of the missing imei. How do i solve this problem? Another problem of mine is my device can't recognized by my pc hence i can't use adb to fix. I tried using via adb wifi but i can't still figure it out. Someone please help me!

This confirms you've lost your IMEI
Do you have backup of EFS partition ? you said in your OP that you tried to flash using qpst, did you ever take backup of your EFS? if yes then I can guide you to restore.
if no backup then it's hard to get it. You can use other phones EFS to restore and change IMEI to yours. since it contains IMEI of others, it's most likely that no one shares it.
PS : Not only 4G you cannot connect to ANY network if you've lost your IMEI.

I still have network signal but its only 3G. I can still receive texts. Unfortunately, i don't have a backup because adb dont work in this phone. It used to work but after getting bootloop, it never show the usb option notification and can't be read in pc. There is a tutorial out there to restore imei and my adb on this device dont work so i can't do anything.
Hi All,
I wrongly restored the EFS partition from another Poco F1, overwriting the EFS partition for which I don't have the backup.
I know the IMEI numbers of the new phone, so I need only to change the IMEI numbers contained in the old EFS backup to use the right ones (overwritten by wrong backup).
How can I do this?
Thanks in advance,
BR
Update: I found the way to restore original IMEIs, but I got "Out of service" state for the inserted SIM. I used both QPST and QFIL, and baseband seems to be OK but anyway radio is always turned off.
My scope is to restore original capabilities (rebuilding the original EFS?): I bought this phone few days ago, and I can prove it's not stolen sending purchase proof in PM (to a moderator).
Is it possible to fix this?

Unfortunately I can't help you with your request. But if the phone is functional, you could enable ADB and see if erasing modem partitions helps. (It probably won't, but you could give it a try)
Code:
fastboot erase modemst1
fastboot erase modemst2

Thanks for your reply.
I already tried, also with the code *#*#25327337#*#*, but it's still not working.
I also tried to use the QPST backup from the same model phone, that I've, and replacing the IMEI (to restore the original in the broken one) but I got "NO SIGNAL". It seems that the radio is not able to be turned on anymore.
Any other ideas?

I already tried this way too and I got both IMEIs displayed in the OS, but the radio is still turned off.
Actually I found no way to turn the radio on, so I sent the phone to the service center (to be "repaired").
Thanks anyway for your time
Same problem
Hi, I had the same problem with a motherboard I bought from Aliexpress, accidentally screwed with the EFS and now nothing works, tried flashing a QCN with my old IMEIs but that failed as well and I'm pretty much stuck where you are. I can't send my device back because I don't live where I bought it and I wanted to ask if you fixed it.

Got the same problem, even restoring the persist.img didn't help. ANy ideas? Anyone got this working, can't activate SIM card. This is totally a software ISSUE. someone must have this figured out.
