Will the device boot up with no error message after replacing it with new battery? Or do you need some programming before or after replacing it?

There is no error when battery is changed.

Just successfully changed my battery without any issue. Booted up normally and able to do everything I was able to do before.

Thank you for the awesome guide :)

The Sony Experia Z5 Compact is water and dust proof. Will heating the back after putting it back on reseal the phone - or is there another step that needs to be added?

You can watch the repair video on youtube: https://www.youtube.com/user/lagaiPhoneS..., but I fixed it here https://lagaiphone.se/shop/sony-z5-compa... they used the adhesive but no water resistant warranty after repair. so far so good!

Pretty annoying, this mentions NOTHING about the battery adhesive strips to order separately, and neither of the “things to buy” come with them. I just replaced my battery, but it’s just flopping around inside at the moment. Where do I order the battery adhesive strips to adhere the battery to the motherboard? Note for others doing this too, you NEED the adhesive strips separately beside the battery and the back adhesive!
