Submitted by DenRaf on Sun, 02/14/2010 - 16:17
This is a short howto for installing an Android 2.1 rom (e.g. OpenEclair) on the HTC G1/ADP1/Dream.
First of all you the Amon Ra recovery tool.
A howto on installing this can be found here
Notice: To be able to continue this howto you need at least amon ra 1.3.2.
I used the recovery-RA-dream-v1.5.2.img. You can find more information on the xda-forum
Then you need to format your SD card. ( Backup your SD card to your computer as you will format your SD! )
A video howto can be found here
But here you have the written one:
- Boot in to recovery mode ( HOME + END )
- Select "Partition SDcard"
- Select "Partition SD"
- It will ask you to confirm by pressing HOME. ( So hit HOME )
- Then you will be able to select the swap-size. Use the trackball to change.
Select the preferred value ( I selected 128MB ) and hit HOME. - Then you will be able to select the ext2-size. Use the trackball to change.
Select the preferred value ( I selected 640MB ) and hit HOME. - It will ask you to confirm by pressing HOME. ( So hit HOME )
Now the formatting starts and will show you some progress - dots. - Select "SD: ext2 to ext3"
- It will ask you to confirm by pressing HOME. ( So hit HOME )
Now the convertion starts and will show you some progress - dots. - Select "SD: ext3 to ext4"
- It will ask you to confirm by pressing HOME. ( So hit HOME )
Now the convertion starts and will show you some progress - dots. - Hit BACK
- Select "Go to console"
- Hit Enter
- Type "reboot recovery" and hit Enter
This will reboot your device directly in recovery mode.
Now you can start the installation of your new Android 2.1 rom. Here I will use the OpenEclair 1.2.1.

Thanks much for providing these detailed instructions. I was able to upgrade my generic G1 1.6 to 2.1 based on open eclair mod.

Good luck everyone. Go OpenEclair!
16. Danger SPL will bring ADP1
I have an ADP1. I found your page trying to find a way to put OpenEclair on my phone. Unfortunately, they say that putting Danger SPL on an ADP1 (at least one that says DVT in the bootloader instead of PVT) will brick it. Since OpenEclair requires Danger SPL, I haven't found a way to put it on there. If anyone has any suggestions for using OpenEclair without Danger SPL or a way to put it on without bricking, I'd love to hear about it :-)
Note: I also have a normal G1 phone as well. It went on there just as you described but without all of the SD card partitioning and Amon Ra recovery tool. I had already rooted and cyanogenmod'ed my phone using the normal cyanogen instructions. I then did just as you did with the radio, then Danger SPL, then OpenEclair.
17. Try looking for open eclair
Try looking for open eclair version 1.2.2, diet eclair. I remember seeing some where that it did not need the dangerSPL.
18. I have an ADP1 myself, and I
I have an ADP1 myself, and I did install the DangerSPL on it and don't have any problems with it.
19. You don't need 2 because
You don't need 2 because danger-spl is a modded version of the adp1 unlocked bootloader for dream.
20. Hi DenRaf, one question pls,
Hi DenRaf, one question pls, I'm developing on adp1 using 1.6 sdk, I wonder if I can continue develop on 2.1 sdk if I do the updating, and most of all, if I have issue in my development, can I safly downgrade to my 1.6 adp1 again? thanks for tips.
21. I use ADP1. hope my practice
I use ADP1. hope my practice might help a bit. I did the flash and it works, all fit in my expectation, great work DanRaf!!!
Apart from what is writeen in this tutorial, might be interesting to note some extra steps for ADP1.
1.install flash_image took me some time, but finally use "adb shell flash_image recovery /sdcard/recovery-RA-dream-v1.6.2.img" works fine.
2.I use recovery mode function to do the sdcard partition, swap, ext2-ext3-ext4, I did not do wipe at that moment, so I boot normaly to copy the 3 zip and done, when trying to boot into recovery mode, it in fact goes back to original adp1 recovery mode ui (a triangle with !), what I do then is do my step 1 one more time and gets into recovery mode, now I dont need to do any partition etc and have all zip on sdcard, the rest is just wipe and flash for each one, it's fast but its hard to be relaxed.
3. when Openeclair1.3.0.1 flashed end, it bring into a animation of flying android robots like leaves from the tree.... instead of the tap sign as youtube tutorial... I was panic at that moment, but I simply need to wait :-)
The best thing is: my old 1.6 dev project start to work with 2.1 sdk with little effort to change, so far all my need works such as sensors and camera preview, video is coming later in OE2.0 so we simply need to be patient. The only annoying part is ddms to catch screenshot crash everytime. adb works all fine. So far I dont have plan to go back to 1.6 but expect OE2.0! bye bye 1.6.

23. nice
yeah so.... i want to run 2.1 on my u.s. G1 but don't have the guts to do this on my own -- anyone have a "2.1 for dummies guide" ?
ha
24. I've installed it on my
I've installed it on my android development phone (ADP) , upgrading from 1.6
to 2.1 and it works fine.
The recovery image was 1.7 I've used
Note that in the linked page on my phone the reboot fast mode is the camera-key + power on key, and not the home key
One remark, the openeclair image sais T mobile, while my phone is the original google dev phone and not the G1 branded by t-mobile (same hardware however)
