I need help unbricking my Nokia Wi2B AP with the ubi error

I look forward to your help. My situation is that I mistakenly uploaded 1 firmware for Nokia wi2b (ipq4019) which resulted in bricking the device.
I then plugged in the UART to read the log. Looks like it has a ubi error. I then tried to backup the ubi from another similar device and loaded it through but it didn't work.
Next I tried to backup rootfs partition and write NAND with memory address 0x0 to 3000000 it started fine, but after I rebooted overlayfs entry was pushed to tmp/overlay.
