Xperia E Dual users were waiting For The Release of Jellybean with GSM working For their devices since a long time but now jjm34, a New Member on XDA have started working on it. And now they got an Alpha Release by them. It can be used as a daily driver. You know that CM10 is freaking awesome.., so Flash it and see the Results.

CHANGELOG:

  • Initial Build

BUGS:


  • Video recording doesn't work
  • Video playback uses software decoders, not hardware
  • Magnetometer doesn't seem to be working
  • USB mass storage speed is slow
  • FM radio not included (hardware and driver work, and tuning works as well, but it's going to require quite a few changes to the audio subsystem to actually get sound out of it)
  • Turning off screen in recovery doesn't work (screen timeout disabled by default)
  • Inserting an unmountable SD card (unformatted, or unknown file system) will trigger a notification offering to format it. However, doing so will format the internal SD card
  • CM's SMS tester to simulate incoming SMS (dev tools) doesn't work

REQUIREMENTS:

  • Bootloader Unlocked. If you have not unlocked it, then Follow this Guide by Sony or FXP.

BEFORE WE BEGIN MAKE SURE TO DO THIS:

  • If you don't have stock JB installed (11.3.A.2.1), you need to flash that first because this ROM only works with the baseband firmware that gets flashed with the stock JB ROM. GSM will be unavailable if you're coming from ICS. If you don't know about this, then find it Here.

INSTALLATION INSTRUCTIONS:

  • Download The ROM From Here and Gapps From Here
Optional: Download any supplemental 3rd-party applications packages for the device you wish to use. (You have to install a 3rd-party app to get the Google apps, like Gmail, Play Store, and Youtube.)
  • Extract the boot.img from the zip, you will need this file for fastboot.
  • Put the phone into fastboot mode(Hold vol+ Button and plug usb to boot into fastboot (blue led):
  • Open a terminal on the PC and enter the following:
fastboot -i 0xfce flash boot boot.img
    fastboot -i 0xfce reboot
    • While the device reboots, press the Volume rockers a few times to load recovery.
    • Once the device boots into the ClockworkMod Recovery, use the physical volume buttons to move up and down. On most devices, the power button is used to confirm your selection, although for some devices the power button is used as a "back" button to go up one level, in which case the home button is used to confirm the selection.
    Optional/Recommended: Select backup and restore to create a backup of the current installation on the Xperia E.
    • Select the option to wipe data/factory reset.
    • Select Install zip from sdcard.
    • Select Choose zip from sdcard.
    • Select the CyanogenMod file you placed on the sdcard. You will then need to then confirm that you do wish to flash this file.
    Optional: Install any additional packages you wish using the same method.
    • Once the installation has finished, return back to the main menu, and select the reboot system now option. The Xperia E should now boot into CyanogenMod.

    Multi-SIM operation:

    • Enable/disable SIM cards in Settings / Multi-SIM.
    • Only one SIM card can have 3G enabled, but it's not toggled automatically. To enable 3G on one SIM you have to make sure the other one is set to 2G-only mode first.
    • Some of the dual-SIM features in Sony's ROM, such as auto-toggling SIM cards based on time, different ringtones, or data usage tracking aren't included.
    • SMS are currently always sent from whatever subscription is set as the SMS send subscription. This includes sending an SMS reply from the "incoming call" screen or the "missed call" notification.
    • Note that battery life is shorter when two SIM cards are enabled. The reason for this is that the modem has to keep switching between two networks to remain registered and be able to receive network events, causing higher power consumption, higher latency, and lower throughput. This also causes the data connection to become slower when two SIMs are enabled. This isn't something that can be "fixed" because it's not software-related. Having only one SIM card enabled will improve battery life and data connection speed.

    USB mass storage mode:

    He has enabled the USB mass storage driver to support mounting two storage devices simultaneously, so you can share both the "internal" and "external" SD cards as UMS.

    Recovery will always mount both storage devices, but the Android GUI for USB mass storage will share the external SD card only, because the internal SD card is intended to remain available to the OS. However, you can manually mount the internal SD card from the shell:

    Unmount storage from the OS:
    vdc volume unmount sdcard

    To unmount forcibly:
    vdc volume unmount sdcard force

    Share to USB:
    vdc volume share sdcard ums

    To disconnect from USB and re-mount storage to the OS:
    vdc volume unshare sdcard ums
    vdc volume mount sdcard
