iPhone 8 motherboard repair and replacement: mind Touch ID

On the iPhone 8, a motherboard (board) fault is often repaired on the board; a board replacement is the last option. Because Touch ID in the Home button is paired to the board, it may not work after a board swap. On an older model, weigh the repair price against the phone’s value.

Key points
  • An iPhone 8 board fault is often repaired on the board.
  • Touch ID is paired to the board and may not work after a board swap.
  • If the board is replaced, the old data is not on the new board.
  • Compare the repair price with the phone’s value.
  • The risk of the repair is explained before approval.

01Signs of a board fault on the iPhone 8

  • No response at all when charging.
  • The Apple logo comes and goes and the phone restarts.
  • Sound, network or Wi-Fi suddenly stopped.
  • It heats up when idle and the battery drains fast.

These signs can also come from the battery or charging port; outside causes are ruled out first at diagnosis.

02Repair or replace?

Because Touch ID is paired between the Home button and the board, a board swap on the iPhone 8 should be considered carefully. Swap versus repair is compared in iPhone motherboard replacement cost.

03Weighing the value

The iPhone 8 is an older model. If the board repair price is close to the phone’s current value, a new phone may make more sense. At Cep Market, after diagnosis we explain clearly whether the repair can be done, its risk and price; the decision is yours. For board faults in general, see our motherboard repair page.

FAQ

Frequently asked questions

01

Will Touch ID stop working after an iPhone 8 board swap?

Touch ID is paired to the board, so it may not work after a swap. In a board-level repair the board stays in place.

02

Is an iPhone 8 motherboard repair worth it?

Compare the repair price with the phone’s value. The options are explained clearly after diagnosis.

03

Can I get data off an iPhone 8 that will not turn on?

Reaching the data usually requires the device to start again; a board repair can make that possible.

04

Will a board repair delete my data?

Data is usually preserved during a repair; still, you need to back up your data before the repair starts (backups are the customer’s responsibility).

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
