Did you input your carriers correct apn ?
If so maybe it doesn't support the band of your carriers 3G/4G

you need to rewrite qcn from a working phone backup. you will need qpst to restore qcn. if you need a qcn backup. let me know i will attach here.

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???

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??
Hello
Download Here
pardon my ignorance, but quick google search seems to suggest this can be used to unlock AWS (1700mhz) frequency on other phones. Is that what we are looking at?
Yeah, what is this?

Can you give me a solution please let .... Thanks
any solution anyone ?
Have you got D802? Thanks!
Hi. I'm lost. I've bricked my freshly purchased H950 because of being in haste to update the firmware to 5.1.1. I've accidentally installed a H955 KDZ over my stock 5.0.1 AT&T H950 firmware. As expected, the device is bricked (everything works except the cell network). I've tried everything, spent about 8 hours with no result. Can't root it as well.
The IMEI and Baseband status is "Unknown" (lost EFS partitions).
Please, if it;s possible, give me an advice how to restore it to its original ATT firmware. I know that ATT hasn't published the TOT file of their firmware. Maybe I could restore it using someone's backed up files?
I'm outside of the US for the next 7 months so I won't be able to return it
Please help me, this is urgent.

Well the good new is that your cell phone works so it is not brick. Cell network probably doesnt work because H955 use different bands than H950. I dont think you will be able to go back to ATT rom because like you mentioned there is no kdz for it. But on the bright side you can try to use the H950PR KDZ to flash your cell. this is totally compatible with the H950 from ATT. You can always wait for the someone more knowledgeable to answer but I am almost sure that it should work.
http://forum.xda-developers.com/g-flex2/general/kdz-compatible-att-h950-t3180847
I've installed the h950pr and there the cell network is still not working
In case if i find a person who has a similar device with Att firmware, how can i make a backup of it in order to flash my device?
I've managed to root my semi-bricked H950. But the imei and baseband version are still unknown. What should I do?
baseband ok. just the imei has 0 value. help please

follow THIS guide and you should be ok.
Use your own imei embedded in the back of the phone or the original box.

Check your PM.
Does anybody know how to write IMEI on the H950 without octopus box? Can't do it in QPST, DFS, EFS pro because it sn't recognized as a phone / doesn't answer.
Everything works, I can even make calls, just the imei value is 0.
Finally I did it!!!

Yeah. I used QPST. I had to open cmd, enter "adb shell", then " su", then "echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable". After that you can backup Nv via QPST.
Im glad you informed yourself and solved your own issue. ?
Hello and thanks for checking this post!
Ive bought a LG G3 D850 in USA, unlocked. When moved to Argentina I was not able to get 3g/4g signal from my local carrier, only EDGE, as the phone wasnt sold by them they rejected to assist so on my own Ive made the following steps:
Hidden menu fixes - didnt work
Edit build.prop - didnt work
Updated from stock 4.2.2 to Fulmics 5.2 - didnt work
Flashed new .qcn files worked as follows:
.qcn #1: I was able to improve quality signal for voice and data, also fixed 3g and H connections.
.qcn #2: Quality signal decrease, EDGE works, no 3g and no H but 4G works.
What I would like to know:
1- Is it possible to use the .qcn #1 and restore my factory IMEI so I can at least have H?
2- Is it possible to edit the .qcn#1 and include the code portion from .qcn#2 that enables 4g?
That would be the perfect fix for this issue!
ps: Ive the original box with the IMEI labels and also the internal label that confirm phone original IMEI, I know change IMEI is not legal and its not what Im trying to do, Im looking for a fix keeping my IMEI stock.
Thanks for any input!
Hi i have the same problem.
Im also from Argentina and also in FULMICS 5.2
Im still no try change the QCN, because can not understand the procedure very well
Can you help me?
where can i find? and You recommend the QCN N.1 , for me is enought H.
Thanks
I hope you can answer
Hi
How can I achieve your flash qcn #1 solution on my lg magna h500?
Im having the same issue
I had the misfortune of bricking my OP8 a while back and ended up having to use SMT mode on MSMDownloadTools. As we all know, this will cause you to lose your IMEI numbers. They return a value of 0. Has anyone come up with a solution to restore the IMEI numbers without having to mail their phone in for repair?
U fixed?same issue

Again, this is why you don't illegally change your IMEI. Now you're likely stuck with a dead brick of a phone because you can't switch back the IMEI either.
