This Lenovo A5500H firmware flash file (stock ROM) will un-brick and restore your device to its default, factory state. If you previously rooted or modified the system partition in any way, flashing this stock ROM will overwrite all existing modified system files to replace them with factory software.
Make sure to backup all valuable data on the phone, like contacts, messages, app data, etc. This is usually a necessary step before flashing, or resetting your smartphone or tablet. After this process is complete, all data on the device is completely lost.
Again, make sure the phone is charged to at least 30%. So the flashing process is not interrupted by a low battery. Interrupting the firmware installation could result in a dead device.
