  8. Use a Spudger to slightly lift up the motherboard. Be careful! You need to thread the display flex cable through a gap in the motherboard while lifting it up. It is also connected to the vibration motor, which still sticks to the phone. Take especially care of the two black connectors on the side of the battery. They break off easily during the removal of the motherboard.

  9. Gently pull out both of the black straps with the adhesive tabs underneath the battery. Never pull out the straps upwards but always sideways. It can easily happen that you rupture the adhesive tabs. In this case use a plastic card to pry off the battery carefully,Use a little bit of heat if necessary! Now you can remove the battery from the motherboard easily.

Thank you for repairing your phone and giving it a second chance.

:)

Tobias Isakeit -

Where do I need the Back Cover Adhesive Strips for?

Visser - Ответить

The guide doesn’t mention that one needs new adhesive for the battery (the one I bought isn’t sold with it). It would therefore be wise to mention what kind of adhesive (two-sided, what thckness, etc.)

Double sided tape is enough to keep it in place, as the back cover and midframe holds everything down for extra reinforcement. Sony sure makes their smartphones !&&* to repair, but that’s another rant.

William Nephew -

Nice tutorial, thanks.

CAVE: I broke off one of the connectors to the magnet-charger contacts on the very edge of the mainboard when lifting it off the case. The same seems to have happened to the author (Step 8 and 9 - the lower one of the two black bridges looks rather wonky)

Pitfall: When lifting the vibration motor (Step 7), make sure you check the cable running on the underside of the mainboard afterwards. It is the connector to the on/off switch. If you unplug it accidentially (like I did), you won’t be able to turn your phone back on after the work is done.

Thank you for the precise guide, I’ve followed it with no major problems and no damage done :)

Just a friendly notice to others that will try this, reversing steps order is not enough to reassemble the phone if you’re not careful. Some parts are tricky such as the need to put LCD tape back through motherboard hole or the need to watch out not to destroy jack/sensor tape when pushing motherboard back. Also, you’ll need a double sided tape to glue the battery back to the motherboard - original tapes are destroyed during disassembly. The camera clamp is tricky to remove without bending it. Also, it seems that it’s only kept in place by back plate pressure. Also, remember or take a picture of how the NFC connector is attached - I’ve had problems figuring it out when reassembling.

All in all, great guide and my phone will work for me for months or even years instead of going to a trash can because of a swollen battery. Thanks again!

Took a couple hours but I couldn’t have done it without this guide, thanks! Lets hope the new battery won’t be dying on me by lunchtime every day :)

After replacing the battery and turning on the telephone my Xperia doesn’t see the SIM card.

I did everything very carefully and I don’t know what can be the reason for that.

It’s not like there’s no service, it just can’t read any other SIM card too.

Does anyone have an idea how to fix it?
