== Problem description ==
Apple iPad Pro 12.9-inch (A1584) intermittently reboots every 10–15 seconds. When connected to diagnostics tools, the panic log reports consistent watchdog resets caused by SpringBoard failing to check in.

== Symptoms ==

* iPad restarts in a loop every 10–15 seconds.
* Unable to reach the Home Screen long enough to interact.
* Panic log contains repeated lines such as:
** “userspace watchdog timeout: no successful checkins from SpringBoard”
** “SpringBoard last successful checkin: 0 seconds ago”
* System may show additional services not checking in (backboardd, mediaserverd, wifid), which is normal when SpringBoard fails first.
* Unplugging all flexes also doesn't fix the issue.

== Solution ==
== Diagnostic Steps ==

==== 1. Read Panic Log ====
Open the panic log from the iPad or using 3UTools:

Look for:

* userspace watchdog timeout
* no successful checkins from SpringBoard
* last successful checkin: 0 seconds

Interpretation:

This is almost always a software-layer failure, not a hardware issue. SpringBoard isn’t responding, so watchdog forces a reboot.

==== 2. Rule Out Hardware ====
Check:

* No signs of liquid or board short
* Battery level stable
* Device boots and displays Apple logo normally before reboot
* Unplug all flexes which may cause reboots.

If these conditions are normal, hardware is not the cause.

==== 3. Perform Clean Flash ====
Use:

* Apple Configurator / Finder
* 3uTools, etc.

Select Clean Flash in 3UTools and Restore in Finder so system partitions fully rewrite.

=== Repair Steps ===

# Put iPad into DFU Mode
#* Connect to Mac/PC
#* Hold Home + Power
#* Release Power after 10 sec while holding Home
# DOWNLOAD Load IPSW Firmware
#* Choose latest signed IPSW for A1584 FROM [https://ipsw.me/iPad6,7 IPSW.ME]
#* Select Restore on Finder (not Update) & Clean flash on 3UTools
# Erase & Flash
#* Allow full system erase
# Allow Full Boot
#* After restore, device should remain stable without rebooting
# Verify Functionality
#* Let it idle for 5–10 minutes to confirm loop is resolved
