Procedure to Install Cyanogenmod 9.3 on Sony Xperia Sola MT27i:
Download latest Cyanogenmod 9.3 package from the link mentioned below.
After downloading CM9.3 package, connect your device to PC. Enable mass storage mode on it. Now transfer ROM package & Google Apps to your device’s internal SD card.
Now disconnect the phone from computer. Boot in recovery mode on your phone. To do so, switch off the phone, switch it on again, when phone is restarting (during boot logo & LED turns blue), press Volume up button. Your phone will land in recovery mode.
Take a nandroid backup of your current ROM so that it can be restored back (in case if anything goes wrong). To backup your current ROM, select Backupand Restore option from the recovery mode & on next screen, select backup. Now It will make a nandroid backup of your whole system (excluding SD card). Wait for the backup process to get finished.
Now Select “install zip from sdcard” & then “choose zip from sdcard“. Navigate the ROM file (which you’ve transferred earlier) Select it & press on ‘Yes‘ to continue. ROM installation process will start.
Wait for the ROM to get installed. After ROM gets successfully installed, your phone will land in the recovery mode again.
(Optional) The same procedure you have to do for installation of Google Apps. (Just don’t do the above step i.e, wiping data after installation of Gapps). After you finished installation of Gapps, press back button to go to main menu of CWM.
Select wipe data/factory reset & wipe cache partition to wipe all the data & caches from the phone memory respectively.
Select reboot system now from the recovery mode to Restart the phone. Switch off it again (since the procedure is not completed yet). Just keep the phone aside.
Now download the ADB & fastboot files which we will need to flash the kernel image.
Extract above rar file to a convenient location/folder (Fastboot Folder).
Open Cyanogenmod 9.3 ROM package using WinRAR or 7-zip, extract boot.img file (which is nothing but a kernel) to any convenient location. (It is located in the root directory of the ROM).
Now move the kernel file (boot.img) where ADB & fastboot files are located.
On the phone (while switched off), enter into the fastboot mode. To do so, Connect your phone to the computer. While connecting press Volume up button to trigger fastboot mode.
Open the folder which contains ADB & Fastboot files.
Runcommandprompt.bat file to open command prompt pointing to the ADB & Fastboot folder.
Type the following command in command prompt to flash the kernel file:
fastboot flash boot boot.img
Restart the phone by typing “fastboot reboot” (without quotes) in command prompt.
