1/ Download the relevant
ROM from either of these locations:
How to check for the December update:
To check if you already have the December Update - turn the device off, then turn if on with 'volume down' and 'end call' held. If the build date is Nov 26 2009 or newer, you have the December update applied.
If not... the December Update is a requirement for this
ROM - use the instructions below to update.
Download the update file
Unzip the downloaded file to a location of your choice on your computer
Copy the “dload” folder and all its contents to the
root directory of your microSD card
Insert the microSD card back into your device
On your device select Settings -> SD card -> Phone Storage -> Upgrade
The upgrade process will give you several warnings which you need to confirm to continue - then press the Upgrade option to begin the update
As the update progresses you will see several screens along with a progress bar
Once complete you will see a confirmation screen, and your Pulse will automatically restart
Pulse WITHOUT December update:
ROM FOR PULSE THAT HAS NOT HAD DECEMBER UPDATE APPLIED
OR...
Pulse WITH December update:
ROM FOR PULSE THAT *HAS* HAD DECEMBER UPDATE APPLIED
... and save the ZIP (do NOT extract it!) to the
root of your SD card
2/ Download the
recovery image pack from: (
recovery IMAGE PACK) and then extract it to a known location...
3/ === SEE BELOW ===
Put your device in
bootloader mode - turn if off, then tap the powerbutton while holding the 'Volume Down' and 'End (Red)' keys
Connect the Pulse to your computer with the USB cable, and then:
- WINDOWS - double click 'install-
recovery-windows.bat'
- MAC - Open a terminal window and navigate to the directory containing the files, and type 'chmod +x install-
recovery-mac.sh' [PRESS RETURN]
...followed by './install-
recovery-mac.sh' [PRESS RETURN] (don't include quotes!)
- LINUX - Open a terminal window and navigate to the directory containing the files, and type 'chmod +x install-
recovery-linux.sh' [PRESS RETURN]
...followed by './install-
recovery-linux.sh' [PRESS RETURN] (don't include quotes!)
The phone should confirm that the
bootloader was copied over, with white text and the number of bytes copied.
4/ Power off the phone - the way I did this, was to remove the battery.
5/ Whilst holding down [MENU] button & [RED] button (bottom right of the front of the phone) *INSERT THE BATTERY*, and quickly press the power button, and then let go of ONLY the power button!.
6/ Wait until you see the
bootloader screen (it has a red flower/peacock-like logo in the background) and select: "Flash zip from
sdcard" - acknowledge this selecttion, by pressing the trackball firmly in.
7/ Your
custom firmware will now flash, and once finished, select "Reboot system now" and press the trackball again, to select this.
