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 Flood illuminator & 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.

Assuming you fixed the root cause of the bootlooping issue, the above 2 options should get you a working phone.

If it still fails at 4013 or still bootloops, then you haven't solve the issue.
