in my case after unlock invalid sim what should i do next?

@asadnow2k
Hello
If after unlock still invalid sim most possible you have latest firmware which not supported yet in GCPro.

for now
 

no solution for this

i have ZV5 firmware read from a phone in which you can unlock succesfully, if anyone need it let me know to upload it so you can test (downgrade at your own risk)

Hi, downgrade will damage security on phone and will brick devices, so please DO NOT DOWNGRADE DEVICES, wait until team add solution for new firmware and security patch
