Hi there, I followed the same steps with same results. Finally found that the network not recognizing was due to downgrading from higher android version. So, i downgraded further to android 7 and then used the rescue tool to move to android 8 os, and it worked. Everything else is reverted to stock except the unlocked bootloader warning on the boot screen ( even though the bootloader is locked, but due to the abscence of signed boot img i suppose the message is not going anywhere.After 2 days without phone, I repaired it again with Rescue and Smart Assistant, and the phone turned on in Fastboot mode, but left me without IMEI. So I reinstalled Lineage and was able to get it back. For fear of bricking it, once again, going down to the official ROM, I'll stay in Lineage.
They are 2 local apps from Argentina. I think the incompatibility stems from the local development of the apps, and not from the ROM, which so far works perfectly (except that you can't lock the phone with your fingerprint).
I use Microsoft authenticator, and it works perfect.
Would want to go with the rom , If you guys can help with device certification issue. I was using Havoc 4.19 on Asus zenfone max pro m1 - there the device shows certified how?
The developer took the effort to resurrect this old device, kindly if possible look into this as well. Thanks.
