Essential Pre Requisites:

  • All the data in your device should be backed up as all the data in your Galaxy ACE S5830 will be wiped off completely. So, to restore the data backup, you need to follow below mentioned steps. Don’t backup the data with the help of KIES as KIES doesn’t support the beta or custom firmwares.

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 70% so as to ensure that device doesn’t get turned Off in the middle of firmware update.
  • Enable the USB Debugging in your Galaxy ACE S5830 from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked as shown in the below screen capture.

If you are on any of the custom ROM firmware, then you will have to wipe the data and clear the cache from the recovery mode. Additionally, go to Advance options in recovery mode and clear the Dalvik cache too.

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.
