after it broken. I try to enter the recovery mode. All below process I have done,but failed.I think it maybe about the battery problem. "Put the phone in "recovery mode": Unplug USB cable. Power off. Remove the battery. Reinstall the battery. While pressing "volume down" button (keep it pressed), press the power key until the jolla logo appears. Release all keys. Phone is now in recovery mode."
The logo cant appear.
