A bootloop on the Sony Xperia M Ultra occurs when the device repeatedly restarts without fully loading Android. This is commonly caused by a failed software update, corrupted system files, or an incompatible app. Most bootloops can be resolved without losing data by clearing the cache partition first before attempting a factory reset.
Factory reset may be needed as a last resort — erases all data.
On your Sony Xperia M Ultra: force restart: hold Power for 15–30 seconds
If still looping: enter Recovery Mode
Navigate to 'Wipe cache partition' → confirm → reboot
If still looping: return to Recovery
Select 'Wipe data/factory reset' → confirm (erases all data)
Last resort: use your manufacturer's PC tool to reinstall firmware
