HI GUYS...
I UNLOCKED MY SAMSUNG GALAXY INFUSE AS USUAL, AND ITS OK "UNLOCKED"...
BUT WHEN I INSERT MY SIM CARD IT WORKED FOR FEW MINUTES, AFTER THAT IT SAYS NO SERVICE AND THERE IS NO SIGNAL AT ALL... BUT SOMETIME I GOT SIGNALS BUT WITHOUT REGISTERED NETWORK.
NOTE:
MABY THE PROBLEM FROM THE IMEI NUMBER, BECAUSE I GOT IT WRONG , IT IS LIKE IN THE ATTACHMENT.
PLEASE GUYS HELP ME ....
Yep, a borked imei number will not allow you to connect to your cellular network...
I'm guessing that your efs folder wasn't backed up... you can try this...http://forum.xda-developers.com/showthread.php?t=881162
I haven't tried this but good luck.
thank you brassguy...
but does this work for infuse 4G ?
In addition, I read that we can change the IMEI number using the ADB, or is there another way to do this?
Also, what about the GSII_repair app, can I use it for my phone (infuse 4G)?
i had this problem last night where i flashed a rom. i return it to stock and imei showed up.
was having a imei" unknown error" and i backed up now on my computer.
ps ebay sales unlock service for 0.99$ if you didn't buy the code and just hacked it with hex or whatever
mine is already unlocked and it's permanent
i do travel over seas alot
But i returned mine to stock many times but the imei number still like this.
I did no get you in the third line???

THERE ARE 3 Total Lines you will need to edit:
00188008
00188010
00188020
or maby I did something wrong
Please guys someone help me to solve this problem ,because I can not use the phone....
No one have ever faced or seen this problem with someone and solved??
this guide is only for phones who has problems with IMEI number on mtk chipsets....
warning: not for phones with valid imei[undamaged], if tried may permanently remove your IMEI.
MOD Edit: Please do not discuss changing/repairing IMEI numbers. Changing the numbers can be illegal in some places and changing the IMEI number is often used for reselling stolen devices.
HIT THNX IF U LIKE............
Thank you
I am about to try!! thank you for the information!

hy,
I have a problem with a chinese dual sim it's a STAR B97 MTK 6575... AFTER A FACTORY RESET , i got a invalid imei.
The problem that I have with your first solution is that after I type the code for the Engineer Mode, in all of those options I dont have "CDS information"... ergo, I cant do nothing.. What do you advise next? p.s. how do I flash my phone stock firmware?
thx a lot!!!
Will this work for MT6589
Please let me know can I use the above method for Mediatek 6589 newly launched chipsets.

I have the new X920 (butterfly clone) MTK6589, and I have this invalid IMEI issue. I can manually get this fixed through your guide entering the engineer's mode. But everytime I reset to factory settings, the invalid imei error comes up. Is there a way to fix this permanently?

i'm also suffering with the same problem but i did not find any perm sol.
i think
it can be done if you have any previous backups of data partition before the invalid imei problem occured.

it is okey to use other backup with the same phone and restore it in the phone with invalid imei?
Hi guys!
Yesterday my firmware update went terribly wrong and now I have a device that states that imei and baseband are unknown, so I my both sim-cards don't work.
I've tried several types of IMEI restoration, but none of them worked.
Unfortunately I don't have any backup for nvram. So, my guess is that there is a problem with EFS partition on the phone.
In QPST NV RF Manager I see my real IMEI from the box, so I guess it is still present, but my baseband doesn't work. Can you please suggest any help on recovering the baseband? Or if it is possible share with me modem backup or nvram backup without IMEI (I've seen on this forum that one guy with Samsung S3 had a kind of the same problem and he was given a working nvram backup without IMEI (IMEI was 0/00)) I can write my IMEI then, if baseband works again. Will appreciate any help.
Send it back. Only the oem is legally able to mess with the IMEI.

Well... I have managed to make it work again and my original IMEI is back. The only thing I had to do is to restore a working NVRAM backup (from another device) via QPST. So, it wasn't that hard. Much simpler than sending it back to China.

If you restored the file from another device then it won't have the right IMEI.

It HAS right IMEI, I checked it with the original box. No need to put up an argument about it. Both devices (mine and the one which was backupped and restored from) are working fine, bot have ORIGINAL IMEI numbers and no errors considering networks or MI accounts. So, actually I have no idea what you are trying to tell me.

I'm not making an argument. I'm trying to figure out how a number which is supposed to be hard coded into the file is then restored by restoring the files from a different device.
As these devices are not sold in the states learning as much as possible is a good thing.
Glad you got it working.

Okay, sorry. I will try to make it a bit clearer=) This device is not sold in Russia either (officially at least), so the only way to get it is to buy from aliexpress or ebay or anything else. In that case the buyer doesn't get any guarantee or official support. So if the device is broken and can't be restored it turns into a garbage. I believe that in the US the situation with that kind of devices is almost the same.
Now, if You are not familiar with QPST it is a software package for qualcomm based devices which can make backup/restore of some non-firmware software from the device (like IMEI, ESN, Baseband, LTE Channels etc). As for IMEI number, basically, as You've said it is hard coded into device so it is pretty hard to get it changed or fully deleted. Here we come to my case of unknown Baseband and IMEI. Though via phone settings I could see: "Unknown", my IMEI didn't change and was stored in the device. The "error" or smth like that happened after the factory reset and my guess is that the file structure of NVRAM was changed. So, backup of NVRAM taken from the working device didn't actually have IMEI or ESN in it, but it has the right file structure without any errors. That is what happened, the file structure was restored without changing any factory numbers.
If you have any questions, feel free to ask

It is almost the same with a few exceptions. One being that their devices are banned from all people that work for the government, sometimes they get stopped at customs due to copyright issues and with the latest news about them coming loaded with malware, most won't buy them.
That makes sense in a way. Not sure why a factory reset would mess up that part of the device as it shouldn't touch it.
Thanks for the info.

I don't know either, but it was an unforgettable experience and a lesson to do backups of everything.
Hi @landslider, what's up friend? I have the same problem but I have no backup hidden partitions. Could you help me fix my device?

Hi! Have you tried flashing China developer rom with Miflash?
Second option: Connect to your PC and run QPST according to one of the manuals (in order for your phone to show up as a COM), run RF NV Manager and look up your line 550 NV_IMEI if it is filled with numbers that are the same as on your box (check HEX above them and numbers should resemble yours from box but written in opposite direction, eg: on the box it is XXXX69XXXXX in the QPST it will be 96). So, if your IMEI is at its place than all you need is a working device from someone to make a backup. Backup must be made in newer versions of QPST in *.xqcn format and than restored to your phone with checked box "allow ESN mismatch"

http:/ en.miui.com thread-315233-1-1.html (replace whitespaces with slash)
There is a thread in official forum where one guy shares qcn backup. There is also an instruction to restore IMEI and baseband. But It doesn't help for me. Network still unavailable.
Can someone give me a general idea of how to restore a lost Sprint baseband? I have a working phone the same model as the broken one, with root access, DIAG and MSL. I have tried modifying and restoring the QCL, and copying the partitions of the working phone, but nothing works. I can restore the IMEI and MEID numbers, but it won't recognize the SIM card and DFS
shows much missing information. I tried copying the NV files but that doesn't work either.
The phone is an unusual model. I have seen guides to restoring specific phones but I need something more general.
Please help
so, the problem is that you have lost it.
you can use z3x without box version to recover imei { your original } and patch certificate to get baseband and sim working.
if you need video tutorial search on youtube. thanks.

Thanks, dude. But as far as I can tell, z3x without box is only for Samsung devices.
can you please tell me your phone model and processor.
because if it it MTK then fix is very easy through engineering mode.
if it is qualcomm then fix might be complicated
if its samsung or lg then fix is z3x without box.
i am also learning, so pardon me if i asked any silly things,

It's a Sonim with a Qualcomm 8909 chip. But listen, I'm not exactly a newbie. Please don't give me simplistic answers. I believe what I've been working on is generally the way to go, I just need to figure out which part to do in what order
Greetings!
I have the phone and after flashing IMEI dropped to some random one (111111111111119 on both IMEI1 and IMEI2). I wrote the proper ones using MOBILETESTER but the phone still shows no signal. What can I do? Can it be IMEI SV or SN problem, as IDK what originally was there and no backup of course.
OK, so I edited the SN number, now it shows the proper one in *#06#, however, it cannot still see the SIM. Now I don't know what to do. Could anyone help me?
BUMP. One more and I'm sadly done with this with no solution…
