Pre Requisites:

  • All the data present in your phone should be backed up as in the process of applying this update, the data might get either lost or corrupted. With the help of below mentioned steps you can easily backup the same. After updating with this release, the KIES won’t recognize the device as it’s a custom ROM firmware.

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 from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked.

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.

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.

    • all credits to the Developers who develop the ROMS for all the users! They deserve all the credit!

    • No. Pradeep Neela is not developing the ROM. A developer called Macleij(Maclaw) based on Portugal is developing the ROM. Pradeep Neela is just sharing the ROM so that people are aware of the ROM. For any bug reports, please contact Maclaw in XDA only. These people do not develop the ROM.

  18. Followed all steps correctly. (Used many downloads from this website and they worked beautifully)
