New versions of firmware for mobile phones are released to correct errors in the operation of devices. Sometimes this software adds additional functionality, but more often the fixes are only technical in nature. When problems arise with the functioning of a mobile phone, it is often possible to remove most of the faults by a simple flashing.
Necessary
- - SETool2 Lite;
- - firmware files
Instructions
Step 1
Remove the SIM card and USB flash drive from the Sony Ericsson K790i. This is necessary in order to avoid data loss. If you leave the flash card in the device, then in the future there may be problems with its recognition in the mobile phone, and the firmware will have to be repeated again.
Step 2
Download the SETool2 Lite program. The program allows not only flashing the phone, but also reading FLASH devices and executing certain scripts for the Sony Ericsson software component. It is advisable to download the latest version of the program from the official website of the developer or from forums of the corresponding topic.
Step 3
Install the program following the instructions of the installer. Run the utility using the icon that appears on the desktop after installation. You select the phone model k790i from the dropdown list.
Step 4
Download the firmware files. For Sony Ericsson, the software has two components - Main and FS. You need to download both files offered for download.
Step 5
In SETool add the downloaded firmware files and press the "flash" button.
Step 6
Turn off your phone. Press and hold the C key of the device and insert the cable into the appropriate port. The application will independently determine the software version on the device and prepare it for flashing.
Step 7
Click the "Clear" button. Download customization files from the Internet and attach them to the MISC Files tab of the program.
Step 8
Press the FLASH key and insert the wire into the phone, holding the C key. After the program window says "READY", you can insert the SIM and USB flash drive into the phone and turn on the computer.
