As soon as you are done with these necessary requirements, we need you to look below and follow the steps you will see there.

  1. First of all, you have to download the two most important files that your Galaxy Chat B5330L requires for an update: Odin3 v3.07 tool from this page and the new Jelly Bean B5330LUBUBMD1 stock firmware. The version for Paraguay devices is available , the Argentinian version is and the version for Panama devices is . Once they are both downloaded and saved on you laptop or comp, you can officially begin our guide.
  2. So, for starters, make sure to use an unzipping tool on the two files. Their content should then appear on your laptop’s desktop, then turn the smartphone off.
  3. After this step, you need to enter the Galaxy Chat into Download Mode, which means that you have to do this: press and hold, at the same time, Volume Down, Home and Power, then press only Power as soon as you spot the Android logo on the display.
  4. Once your phone is in the Download Mode, you should continue by plugging the handset to your laptop. As soon as the Odin recognizes your device, you will spot an “Added!!” message and a yellow-colored ID:COM box.
  5. When neither is present on the screen, you need to use another USB port or make sure you flash the USB drivers once again. But if the plugging did go as planned, then simply move on the next task.
  6. [sc name=”banner-jos”]Here it is: tap PDA, choose a file with CODE in the name, click on Phone, opt for a file that has MODEM in the name, tap CSC, choose the file which comes with CSC in the name, click on PIT and be sure to select a file with .pit as its extension.
  7. You will now have to do this: select those boxes which are called Re-partition (if you opted for the .pit file), F. Reset Time and Auto Reboot. Be sure to start the flashing of the update file by looking for “Start” and tapping it.
