How to restore iPhone?

My iPhone 5 was dead again.  (Yes, yes, I still use iPhone 5.  I plan to do the upgrade before the end of the year.)  The phone went dark and cannot be booted up.  It showed the Apple logo for a while and went dark again.

The trick of pressing home button and power button together did not work.  I had to do the hard restore at the end.

Restore iOS

  1. Make sure the latest iTune is installed on the Mac.
  2. Connect iPhone to the Mac using the cable that came with your device. (This is important.  Third-party cable may not work.)
  3. The message: "There's a problem with the [your device name] that requires it to be updated or restored." will be displayed on the Mac.
  4. Click Update to reset the phone.
I was able to get the phone back in 20 minutes.  Do not click on the Restore button, which will set the phone back to the factory default.

The Bose Soundbar 700 Won't Connect to App

Bose has one of the best speaker sound. I learnt about Bose more than 25 years ago and still a fan.  I bought Soundbar 700 in 2018.  It took me a while to set it up but it has been giving me troubles once a while.  Recently, I was not able to connect Soundbar 700 with my phone.  Done the factory reset on the soundbar, it didn't work. I spent hours reseting everything multiple times and finally I found this article,  https://www.bose.com.au/en_au/support/articles/HC1380/productCodes/bose_soundbar_700/article.html .  Tweaking them all and finally got it to work again. I think the most important setting is to TURN WPS OFF on the router!  Hope it helps.

Brivis Heater - Error Code #69

My Brivis HX23 Heater broke down this week.  H01 Code #69.  This code was not even listed in the User Manual!  Searching around the web and here is what I found: Secret Reset: This is not in the User Manual.  On the networker controller press FUNCTION > 1 > 4 keys and the screen will go blank and come back on after 30 seconds, this has rebooted the main PCB and reset the fault code. Use this with caution as too much gas build up could cause an explosion. Use it only after the unit has enough time to air out the gas build up. What is Code #69 or any other unpublished codes?  The best way to find out is to open up the heater unit.   There is a little LCD on the PCB showing what error exactly is. (Note: Opening up the unit may void your warranty.)
