A bootloop on the Samsung Galaxy J1 4G occurs when the device repeatedly restarts without fully loading Android.

Factory reset may be needed as a last resort — erases all data.
On your Samsung Galaxy J1 4G: 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 Samsung Smart Switch on a PC to reinstall firmware
