Note: I don't know if this will work for you but it did work for me. Please refer to what happened to my phone why it stuck at black screen after the cherry mobile animation flash screen when I rebooted it.
2. After download, save the file into the root of your SD Card (save it just outside most of your SD card not in folders). Then turn off the phone. Please make sure your phone is charged as least 15% to avoid the phone from shutting down while installing the software.
3. Press and hold the power + volume up button together for a few seconds and a green screen will shows but DO NOT release the buttons yet until the red screen shows up.
4. After releasing the buttons, an animation would appear then a few selections. Select "apply update from external storage" and select the file you have downloaded. Use the volume keys to select and the power key to confirm.
5. The software will install. After the installation, just select 'reboot system now'.
Yan lang po yung instructions. After po magreboot nyan, good as new yung phone nyo po. Balik sa dati yung phone nyo. With instructions pa on first use. Hehehe. Pag gumana po sa inyo, comment lang po kayo sa baba para malaman din ng iba kung working ba sa inyo at kung kanino naman hindi.
Thank you :)
