> order), I just wanted to share my "not so awful" experience with the
> 1.1 firmware update.

> Basically I wanted to backup my 1.0 system and my user data before
> doing anything with the 1.1 firmware.

> I found this very good entry from Anton Melser (merci bien Anton, JF
> and the people from xda-developer that have released Nandroid, you
> just rock): http://antonmelser.org/open-source/backup-install-restore-adp1.html

> You will in Anton's page anything you need to backup your ADP firmware
> before doing any update (yep this is quite important isn't it?).

> As I am on a Mac I had to find "fastboot" (http://
> android.git.kernel.org/?p=platform/system/
> core.git;a=tree;f=fastboot;h=e652b9698f7d2ed17b3c086ee69c911793bc9fdc;hb=HE AD)
> but I didnt have time to do the complete git checkout so a quick
> search and voila:

> - more infos about "fastboot": http://android-dls.com/wiki/index.php?title=Fastboot
> and also on http://www.gotontheinter.net/content/fastboot-cheat-sheet

> - download precompiled "fatsboot" on Mac/Windaube/Lin:

> Then after doing your backup as Anton described it, you just need to
> get the famous 1.1 firmware. Ahhh, I was forgetting that there is no
> official one for ADP. But hopefully the "Holiday 1.1 firmware with no
> check" (what a freaking naming...) works perfectly on ADP so I grab it
> at http://andblogs.net/images/

> Just download the one named "ADP 1.1 Official Update.Zip (No Device
> Checks!)": http://andblogs.net/downloads/signed-holiday_nochecks_devphone-ota-13...

> Rename it to "update.zip" and put it at the root of your micro sd card
> and then poweroff your phone. Power it on with the usual Home+Power
> sequence so that the update is just took at boot and then ALT-I/ALT-S
> (eventually ATL-W for a wipe then reboot and redo the ALT-I/ALT-S) to
> install the new firmware.

> I do recommend to have your phone battery fully charged or to have
> your phone connected to your computer thru USB.

> The firmware update will proceed (you will see a progress bar) and
> then you will have several reboots (2 or 3, sorry I dont remember -
> the one that scared me what about updating the radio firmware).

> After that, you have a new ADP with 1.1. The good news is that you
> dont have to mess up with activation anymore even if you dont have any
> SIM card plugged. This new firmware just allows you to skip the
> registration process so you can then go to the settings and activate
> Wifi and then do the registration when you want (for gmail /gtalk or
> accessing Market).

> You can just verify the firmware version from "Settings/About phone".
> Mine are:

> Model number: Android Dev Phone 1
> Firmware version: 1.1
> Baseband version: 62.33.20.08H_1.22.14.11
> Kernel Version: 2.6.25-01845-g85d4f0d android-build@apa27 #27
> Build number: holiday_devphone-userdebug 1.1 UNLOCKED 130444 test-keys

> Then if you want to see the "paid" apps into Market, you really need
> to have a SIM card plugged into ADP. Without it I could not see any
> paid apps (very weird isn't it? Probably a nice bug in Market). I
> recommend to plug your SIM card then to go to Market sections
> "Applications" and "Games" and then you can get rid of your SIM card
> and you will be able to see the "paid" apps.

> Ahhh just one last thing: what about my user data from 1.0 firmware.
> Sure, simple as using 'fastboot" only on the userdata partition with
> the data.img you got from the backup. Grab the nandroid backup from
> the sdcard (and save it very carefully!) as it contains everything
> from your phone state before the update. Then just use fastboot:

> # fastboot flash userdata "your data img"
> # fastboot reboot

> Voila, you will have an ADP with 1.1 firmware, paid apps and your
> previous user data (apps and all your crap...)

> Enjoy and feel free to comment and share your experience.

> PS: it would be really great of Google was releasing SOON an official

> PS2: yes during this process the radio firmware has been updated from
> "1.22.12.29" to "1.22.14.11". If anyone knows what this update is
