How to Fix Bootloop — BLU G40
The BLU G40 is a 2022 Android 11 smartphone with 3GB and 32GB internal storage. It features a 6.0", IPS LCD, 720.0x1440.0 display and is available in Black, Blue, Green, Cyan, Teal, White.

A bootloop on the BLU G40 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 G40: 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
