Problem description
Diagnosis and repair of an iPhone 12 that boot loops and only shows the Apple logo on screen.
Symptoms
- Shows Apple logo for about 5 seconds, then blank, then Apple logo, then blank.
- Sometimes it shows a green flash for a second.
- If you try to flash an update or restore, it fails right away with an Error 4013.
- If you flash on 3U Tools, it fails at 19%.
Solution
Flex Cables:
- Step 1 in this case is always unplug all the flex cables.
- Ideally test the board with known good screen, battery & charging port.
- If it boots, then one of your flexes is the cause.
- 99% of the time, it is the ear speaker flex. The flood illuminator and/or the ALS has liquid damage.
- The ear speaker flex is paired to the logic board for Face ID.
- If you want to keep Face ID, you'll need to repair the flex. If Face ID is not important, then you can just replace the flex.
- To repair the flex, you'll have to desolder the component & clean out all the corrosion, then place them back.
- If the corrosion is too severe & it damaged the flex, then you'll need to swap the flood illuminator and ALS to a new flex, otherwise, you'll lose Face ID.
- In some cases, another flex can cause this issue like a bad charging port.
- In this case, just replace the flex
Please Note: If the phone is stuck in Recovery Mode because it failed at the Error 4013, you have 2 options
- Kick the device out of Recovery Mode using 3U Tools. In the main screen of 3U Tools, you'll see a button that says "Exit Recovery Mode"
- You can attempt another update or restore.
