IMEI Changed after upgrade

I've upgraded the software to wm6. As it is mentioned before it changes imei. Not a big problem normally.
BUT
Im living in Turkey and here, to use a phone you bought from another country, you have to register the imei of the phone. Upgade process added 2 digits (25) at the end of the imei. And since imei is a standard code they wont accept this code for the registration process. Since i dont have a serial cable i cannot use xda imei changer. is there a way to revert this back? maybe by using another rom or phone-based application?
Thanks in advance

No panic. The IMEI didn't change.
What you see is IMEISV, an extended IMEI with software version number. It has 17 decimal digits(14 digits plus 1 check digit plus 2 SVN digit). 14 most significant digits of the IMEISV without the SVN is the originial IMEI. The last 2 digit identifying the revision of the software installed on the phone.
For example, the IMEISV code 35703600-CCCCC-D-EE
35703600 identifies that it is HTC prophet model
CCCCC is the serial sequence of the model, uniquely identifying a unit of this model
D the Luhn check digit of the previous 14 digit IMEI
EE the 'software version number'
The SVN allows the manufacturer to identify different software versions of a given type approved mobile. The SVN is a separate field from the IMEI, although it is associated with the IMEI, and when the network requests the IMEI from the mobile, the SVN (if present) is also sent towards the network.

any free solution for IMEI change?

Hi , any free solution for change imei in magican ?
is my own used for work with other sim card ,not stolen, need to change, to avoid register same imei number with my private sim card in operator base.
no. the imei is hard wired.
it is also illegal to change it. the imei no is am international id number for that particular hand set.
in australia if phone is reported stolen, the imei no is blocked and the phone is rendered useless.

Need A gurue apperently

This phone is locked and can not be unlocked.. I bought a phone on ebay plugged my Sim card in booted up and was prompted for an unlock code. I then called my service provider and he said he could not help with that but if I entered the wrong code in 10 times the phone would then ask for a puk Code. Well we completed this but it never asked for the PUK code. Instead, it gives me the message "This phone is locked and can not be unlocked"..
I have called the original service provider and the maker of the phone. reputedly. I still have a locked network and only emergency calls only. I found a website that gave me instructions to get to the screen where you can unlock the network by pressing2945#*850# in the dialer which gives you 5 options;
Network unlock - where I get the same message again
Service provider unlock - your phone is not personalized
Network SubSet- your phone is not personalized
Corporate- your phone is not personalized
SIM/USIM-your phone is not personalized
I really need help LG G# 850
Ps. when I called the original service provider and gave them the IMEI number she said the phone is clean and not blacklisted or any thing. Just FYI

nexus 5 ,recognize sim recognize carrier but no service

its begun all of a sudden
i have try to replace sim . i have checked anntena connections inside the phone.
also i have flushed older version of stock android.
nothing helps
anybody have any idea?
Is it possible the phone has been blacklisted?
it was purchaced in usa and i do not live in usa
I understand but if the carrier subscribes to the blacklist database, that may be a possible explanation.
i do not know how to check if its blacklisted
Open the dialler, type *#06# and enter the imei here: https://swappa.com/esn
