Can I to flash Blu D790l whit D790 flash?

Hello friends, I have a Blu D790l says invalid IMEI by pressing * # 06 #, ofcourse not catch network. I tried to repair it with NCK, but does not worked. I think has damaged flash. My question is if I can flash this model with a flash of D790 without the L at the end. It’s the one I could get. I also intend to flash whit SP_Flash_Too . If someone has a manual that can facilitate me, I appreciate it. Thank you very much in advance.
