Tools Required

Safety First
Power off, discharge below 25%, remove the SIM tray, ESD protection. Never apply hard pressure or metal tools to the inner panel.
Inner Foldable Display Replacement
The inner panel is supplied as a service assembly. The device is split along the hinge, the battery disconnected, hinge and bracket released, and the new foldable assembly fitted and re-laminated. The costliest, most delicate repair.
Cover Display Replacement
The 1.9-inch cover display sits in the upper outer half alongside the cameras — replaced and re-adhered after disconnecting the relevant flex.
Hinge Service
The clamshell hinge can be cleaned, re-lubricated or replaced if it grinds, sticks or fails to hold angles — requiring full disassembly.
Battery Replacement
The single cell sits in the lower half. Disconnect the connector, release the adhesive and fit the replacement.
Charging Port (USB-C) Repair
The USB-C port is on a lower daughterboard. Clean first; replace the sub-board if charging fails.
Water Damage
IPX8 resists water but not dust. On ingress, power off and bring in fast for board cleaning.
