The LG K4 is a 2016 Android 5.1.1 smartphone powered by the Mediatek MT6735M - K120E, K130E Qualcomm MSM8909 Snapdragon 210 (28 nm) - K121 with 1GB and 8GB internal storage. It features a 4.5", IPS LCD, 480.0x854.0 display and is available in White, Indigo.

A bootloop on the LG K4 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.

4

5

Select 'Wipe data/factory reset' → confirm (erases all data)
