Reading unlock codes...Done

it was done and imei was normal again, i reboot the phone but the phone wasnt asking for a code and yeet the signal bar was missing, so i flash the phone using fastboot mode using this command
[Spoiler]fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash dsp adspso.bin
fastboot flash bootloader bootloader.img
fastboot flash recovery recovery.img
fastboot flash logo logo.bin

fastboot erase DDR
fastboot erase cache
fastboot erase userdata
fastboot flash oem oem.img
fastboot flash vendor vendor.img
fastboot oem fb_mode_clear

the flashing progress was done but when it boot, it gives error
1. "Motorola Modem Service has stopped x cloase app", then
2. "There's an internal problem your device, and it may be unstable until you factory data reset." and cannot enter menu

i was try flash again using Software Upgrade Assistant
but the problems still remain.

1. do you have solution for this?
2. How do we restore the backup file with .skb extension? and can it restore using fastboot mode? as when the last procedure was writing file on fastboot mode. because i cant enter menu to enable adb and diag to repeat the unlock progress
3. does moto e5 play bootloader can be unlocked?

pardon me it seems that spoiler doesnt work
