The InnJoo Halo Plus, a low-cost 5.5-inch Android smartphone, is known for chronic issues: many owners report battery degradation within months, stuck-on-logo bootloop after update experiments, low RAM causing system lags, poor usable internal storage, and frequent “app has stopped working” errors. Several users also complain about poor camera performance and slow touchscreen feedback. Battery availability and support are major pain points.
Flashing this official firmware (20161219_5.1) brings the device back to factory state, clears severe system bugs, repairs devices stuck at the logo, and fixes Google Play and stopping app errors. It’s also the only way to revive Halo Plus if a failed mod or root bricks it.
