Upgrade Galaxy Y Pro GT-B5510 to Android 2.3.6 Official Firmware (CELK2)

There’s finally new official firmware to report: CELK2 Android 2.3.6 Gingerbread. The smartphone to use it on: Samsung Galaxy Y Pro GT-B5510.

Here are the requirements: turn USB debugging on, make backups, download the official firmware (Android 2.3.6 Gingerbread B5510CELK2) along with Odin tool, get the appropriate Samsung’s USB drivers on your laptop (they have to be the ones meant for your phone model) and charge the phone’s battery.

The tutorial on how to install this update on the phone is below.

Important instructions

  1. Unzip the firmware archive and wait for .tar (among other files) to appear in the list. Then unzip the content of the Odin archive and wait, again, for Odin3 v3.07.exe to be featured on your comp. Now turn the Galaxy Y Pro GT-B5510 off.Galaxy-Y-Pro-gt-b5510
  2. The handset needs to be booted into Download mode; which is done by simultaneously selecting the keys labelled Home, Volume Down and Power, at the same time, for about five seconds. Once that mode is reached, you will have to run Odin3 tool as Administrator and then plug the phone to the laptop. After you see “ADDED” under the file’s message box, you will be requested to opt for some files; they’re the ones in the B5510CELK2 folder:
    – tap on PDA and choose .tar (it should feature *code* in the name)
    – tap on Phone, then choose the file which contains *modem* in the title
    – click on PIT; find .pit and opt for it.
    Select the following two boxes: F. Reset Time and Auto Reboot (should you use the .pit file, you need to choose a box called Repartition).
  3. The time has come to tap on Start; the flashing of the phone is going to debut and you will be asked to wait for the device to reboot on its own.
  4. As soon as you notice “PASS” with a green sign behind the Odin tool logo, you will need to unplug the phone from the laptop. That marks the end of our guide. You should next go to the handset’s Settings and choose About phone; this will tell you if the update was successful or if you need to redo our tutorial.

If something goes wrong

If you’re a newbie, you may come across problems when installing an update or rooting a gadget. Let’s say that your Y Pro B5510 refuses to work after the booting stage; you can make it all fine again with this guide.

  1. Go to Recovery Mode.
  2. Do a Factory Reset/Wipe Data.
  3. Step three: opt for the system restarting. In the end, your Samsung Galaxy Y Pro GT-B5510 will be updated to the Android 2.3.6 Firmware.

      The Tap / modem / .pit files are available into the B5510CELK2 folder.

    This method would not work!
    This will:
    1. Download the latest firmware for your phone from samfirmware. Find a tool called Odinatrix, this will split the firmware file (made for KIES) in 3 files Odin can use. This will take 1-2 hours, but it will be worth it!!! Surly you need your drivers installed, I assume you have.
    2. to boot the GT-B5510 in download mode first plug in USB, so you see the battery charing. Unplug, with volume up+home (it appears the phone is off). Press power while still holding vol up+home. When phone flashes, release power still holding vol up+home. Quickly before phone flashes again press power again and hold, still holding volume up+home. The phone will boot in download mode.
    3. Now open Odin 1.85 add the 3 files made with Odinatrix, if you got this far the filenames are easy to put to the right box. but put the modem file in the phone box. Rest is self explanatory. Select no options in Odin.
    4. when the phone reboots your firmware is updated and your phone unbricked! If it bootloops you need to enter diagnostic mode. Same as above only use volume down. Wipe cache and user data. Reboot and tada!!
    I have done this many times I own the GT-B5510 for years because I love it, it is so great for sega and nes snes emulators due to the keypad.
    Yeah thank me!

      Number 2 does not work.
      I never get into download mode.
      – Battery charging then unplug, while holding volume up+home: OK
      – While still holding vol up+home pressed, press power and hold it pressed: OK
      – the display shows “Samsung Galaxy TXT” and the keyboard illuminates for 1.5 seconds: release power still holding vol up+home: OK
      – again press power again and hold, still holding volume up+home: OK
      – All goes dark and nothing happens

      – …?
