    • A thumbnail is all that is needed to remove the microSD card from its housing in the inner case.

    • The simple design of the Mini E10 allows most components to plug directly into the logic board. The only exception is the external microSD card slot.

    The external card slot is microSD not SIM.

    • A single T5 Torx screw and a few plastic clips are all that secure the antenna assembly to the inner case.

    • The antenna assembly uses simple yet effective pressure contacts to make a connection with the logic board. No connectors necessary!

    remember to take out the bottom two screws

    • A couple more T5 Torx screws secure the rear inner case and logic board to the rest of the X10 Mini E10i.

    • Disconnect the battery connector from the logic board with the flat end of a spudger.

    • Rotate the logic board upward out of its cradle and use an iPod opening tool to disconnect the display data ribbon cable.

    • The shields covering the majority of the chips housed on the logic board protect their sensitive circuitry from electromagnetic interference.

    • Big players on the board include:

    • Sensors near the top of the board face outward from the front of the phone near the earphone opening.

    • A proximity sensor turns off the touch screen when the phone is against your face.

    • A light sensor automatically adjusts the LCD brightness for optimal viewing in any lighting condition.

    • Further prying around the perimeter of the front panel assembly allows the LCD assembly to be separated from the front panel.

    • The digitizer is manufactured by Synaptics, with the main touch screen controller labeled as T1021A 1 0942 AC0P876.

    • Interestingly enough, this is similar to the digitizer found in Microsoft's Kin Two.

    • A Samsung LMS255GF02 takes care of the Mini E10i's display needs.

    • And just like that, the dark deed has been done.

    • Thanks, Sony, for keeping it simple.

    How to replace a broken SIM holder

he great take apart, do you need to dissemble the whole phone to replace the power button cap?

Alex - Reply

More or less. It's been a while since I took this apart, but I think you'll have to take the logic board out (work up to step 9). Luckily, this phone is really straightforward to disassemble.

Andrew Bookholt -

so you can't use BST-38 Size: (5.5 x 48 x 40 mm) battery instead that one you have on the picture (or BST-41 some sellers on Ebay say it is compatible) ???

Hi There

This is a fantastic guide, and has enabled me to get the battery out, does anyone know where on earth I can buy one of these, I have searched all the usual channels, google ebay etc, but can only find batteries for other models that look nothing like this.

Any help would be much appreciated

All the best - Trev
