Problems after unbricking a Zenfone 3 Max

Hello I have Zenfone 3 Max ZC520TL. Recently, I bricked the Zenfone. Luckily I figure out how to unbrick it and it worked successfully. The inconvenient that I have right now is no network signal due to unrestored NVRAM and NVDATA. So what's the problem here? It's impossible to root (I tried a lot of methods and nothing), I cannot open the bootloader (open the bootloader to install the TWRP and restore) due to null Serial Number (I guess). So I need to restore those Nv's (I have those Nv's saved, backuped) to put on work my network signal and data
So, if someone knows how to solve this, please help me

Thank you!
