____/\_____ MAUI META by MediaTek....
finally managed to permanently fix the erasing problem of imei on flashing new ROM or factory resetting phone ....
mobile uncle tools or... engineering mode temporarily fixes the imei problem by pasting what's known as "Soft Imei" and which tends to get erased on formatting or flashing new ROM .
also in KitKat the security is so optimized that engineering mode doesn't accepts the imei
now this method I'm sharing with you permanently fixes the problem of accidentally formatting NVRAM using sp tools.
Things you need
NVRAM DB FILE MT6582 : http://www.4shared.com/rar/vbnwUC_ab...2_DB_File.html
MTK65xx ADB VCOM Driver :
now follow these steps:
1> install all necessary drivers.
2> install MauiMeta software.
3> turnoff the phone.
4> open Maui software goto option and select " Connect Smart Phone Into A Meta Mode" and hit reconnect
5> connect the phone in off mode.
6> it will detect and then on upper left corner tab select "Write Imei" option a new window will open.
7> click on "Change Nvram Database File" and select BPLGU file from MT6582_DB file.rar after extracting it.
8> Now just write 14 digit imei imprinted on back of your phone and 15th digit will be automatically generated for both Sim's.
9> Press download to Flash.
10> close that tab and hit disconnect.
now flash any ROM or factory reset it imei will be automatically recovered ...
