Phone [ROM] [STOCK] [Nandroid] Alcatel one touch 918a

Hello, thanks for the interest in advance, to the point.. I have a Alcatel one touch 918a, rooted and custom rom from a developer called mark.. Is now in gingerbread 2.3.6 and is running fine, but the cellphone is sim locked and i want to unlock it.. I buy a unlock code from a imei unlock service and they give me the unlock code.. But like all you all ready know, i can't insert the unlock code in a custom rom so i need the nandroid backup files from the original factory rom installed or i need a flasheable zip version of the original stock rom and that's would be great.. Or alternative method for insert the unlock code i don't know maybe in terminal emulator command or something like that.. So i really need unlock this cellphone and i don't have acces to computer for use the alcatel one touch software for install the original rom .. Thank you very much for read and for all yours helps in advance..
