Firmware Finder to rolling back into EVA-L09C02 (Vodafone)

[D4rk_W0lf]

Hi, I rolled back from Android nougat EVA-L09C02B346 if i recall correctly to MM because i wanted to see if my battery last longer (i thought it but the drain is near the same..) and to test performance. I used the double "update" method from huawei and now i'm stuck into EVA-L09C900 and i get no updates to go back into Nougat.. In Firmware Finder if i use the old code i had from my Huawei, (the L09C02) in the update B346 with the imei check i got a message saying that i can install that update but i don't want to take any innecesary risks.. I can use FF to update right into that version or i have to do something more difficult? thank you and sorry for my bad english
