Where are the battery installation and reassembly instructions?
Just go back in reverse order, Einstein
I replaced the battery on my Huawei Honor 8 and after power up it doesn’t see the SIM card. There’s no way to install the sim card tray backwards or put the SIM card in wrong. Any ideas?
Never mind. I figured it out. The metal SIM card cage got distorted and the tray was sliding in behind it, not into it. I gently bent the cage back into shape and all is well.
Do I need to apply new adhesive ? or re-use what is already on the device?
