How to Fix Bootloop — BLU C4
The BLU C4 is a 2018 Android 8.1 Oreo smartphone with 512MB and 8GB internal storage. It features a 4.0", IPS LCD, 480.0x800.0 display and is available in Black, Gold, Blue.

A bootloop on the BLU C4 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 BLU C4: 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
