Essential Pre Requisites:

  • All the data present in your Samsung Galaxy Gio handset should be backed up only with the help of below mentioned options. Don’t make use of KIES to back up the data as KIES won’t support the custom ROM firmwares. In the process of the firmware update, there is a possibility that the data may get lost or corrupted.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log - Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Minimum charge left in the device should be at least 60% so as to ensure that device doesn’t get turned Off in the middle of firmware update.
  • Disable all the antivirus suites in your computer and uninstall the same in your device as these tools generally tend to interrupt the process of firmware update.
  • Enable the USB Debugging in Galaxy GIO from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked as shown in the below screen capture.

USB Debugging

  • Just in case of you are on the custom ROM firmware, you need to ensure that you have disabled the Lag fixes if any installed from the recovery mode. You also need to ensure that the Dalvik Cache in your phone too is wiped off so as to ensure that just in case if any data cache is there that too is wiped off completely. Its very important for you to root your device as this will only work on the rooted phones and not on the unrooted phones.

So, assuming that you have followed all the instructions you can now proceed to the next page where we have mentioned the detailed instructions on how to apply this firmware.
