PART 2: HOW TO FIX LOCK-UPS ON KINDLE FIRE DEVICES
I have tried various means to unlock my KF1G, by holding the on-off switch for 15-25 seconds until the device turns off. I wait for a few minutes and turn it back on again. Most of the time it begins to boot up, but locks up again when the arrow appears. I simply leave it turned on, connect it to the power cord to recharge, and hope if I leave it long enough it will eventually boot up. So far that has worked for me; however, someone else suggested that once your KF boots up and you are eventually able to access your files, open your SETTINGS, click MORE, then click DEVICE, then click RESET TO FACTORY DEFAULTS. This will wipe out all the things you have stored on your KF, but those items are still available in the Cloud files at Amazon.Com, and you can reload them after you reboot the KF. Although games are fun to play, I would advise staying away from freebies with ads or trial games. Like I said, I cannot prove these are the culprits for locking up your KF, but I have not had any further problems with my KF1G since I reset to factory defaults and reload with only those programs I feel comfortable using. Although KF acts like a computer, I am not aware whether you can install any anti-virus programs to protect your files or not. I don't think you can, so have to rely on Amazon to do that job for you. I hope this is a help to those of you who are frustrated with lock-ups.
