This is not the official release, just a check out from the master branch which is under continous development. Some important things before you jump in - there are no Google apps like Market, Gmail, YouTube etc., camera doesn't work correctly and the system is still few yards away from being ready for everyday use.

Requirements:

1. Dev bootloader.

2. fastboot, if you changed the boot pic, this will be setup already, else read here, also setup ADB as mentioned in the link.

3. Cupcake images (thanks to Disconnect).

4. JFv1.41, make sure you are running this latest release.


Steps:


1. Turn off the phone and go into recovery mode (HOME+POWER) and press ALT+B, this will start the backup process. Necessary because you would want to go back to your normal life after you have had enough of cupcake.

The backup will be stored on the sd card in 'nandroid' folder, so make sure the card is inserted and not full.


2. Turn off the phone, remove the sd card, go into bootloader mode (CAMERA+POWER) and connect to PC, you should see the bugdroid skateboarding, if not, you do not have dev bootloader(sigh!)

Press Back once, the screen should show FASTBOOT.


3. Start command-prompt/terminal on your desktop, cd to the unzipped cupcake images folder 'master-nonopt-..' and enter the following commands,

fastboot erase boot

fastboot erase recovery

fastboot boot kernel ramdisk.img

The phone will reboot after few secs to test the new image, if everything goes fine you should see the Home screen. Keypresses, touches will not work, so take out the battery to turn off the phone.

Go into bootloader mode, press Back so that FASTBOOT comes up and enter...

fastboot flash:raw boot kernel ramdisk.img

Kernel and boot image are done, what remains is system image(/system) and userdata image(/data), so..

fastboot flash system system.img

fastboot flash userdata userdata.img

And finally reboot the phone,

fastboot reboot

Thats it. The phone will take some time while booting, patience!


---------------------------------------------------------------------

Going Back To Your Backup

Time to head back home to Gmail, YouTube and syncing.


Steps:

1. Copy 'nandroid' folder from sd card to desktop, you can do this the usual way by selecting 'Mount' from the USB notification in the status bar or use a card reader.

2. Turn off the phone, remove the sd card from phone and go into bootloader mode. Connect phone to PC, press Back button so that FASTBOOT shows up.

3. Start command-prompt/terminal on your desktop, cd to the nandroid folder and enter following commands,

fastboot erase boot

fastboot erase recovery

fastboot flash system system.img

fastboot flash boot boot.img

fastboot flash userdata data.img

fastboot flash recovery recovery.img

And finally reboot,

fastboot reboot

That does it. Phone will take some time to boot.
