Before I got started on hacking the Poco (e.g. custom splash graphics, maybe repartition for dualboot, who knows what else) I wanted to port-over my Low-level Backup/Restore kit from Mi A1.

To my disappointment I have discovered that the EDL mode on the Poco is protected by some proprietary Xiaomi authorization.

This is the same problem encountered as those many who have bricked over anti-rollback protection in other devices - they cannot get authorization.

So, in summary - EDL flashing is not possible as Xiaomi have locked it to authorized machines only. Avoid messing around with non-standard-Android partitions at all costs.

I guess we can bring this up to Jai Mani since he insists that this phone would be custom development friendly.

Off-topic: Glad to see you here since I also owned Mi A1 and saw your great work in that device
