我的8668，按键发黄，固件过旧，哪位大神可以帮我翻新一下，实属感激不敬

自己动手，换外壳换按键，更新固件

自己动手换个壳子就行了

旋钮时间长了开裂，有替换的么

Does anyone know a teacher who can refurbish a P8668i?

My 8668, the buttons are turning yellow and the firmware is outdated. Could someone please help me restore it? I would be very grateful.

DIY: Replace the case and keys, update the firmware.

Just replace the case yourself.

The firmware won't be complete.

解决了各位老师，90在海鲜市场买的壳子和固件，翻新成功力（完全胜利）

The knob has become cracked over time; is there a replacement available?
