I have my N1 rooted and after I installed BlackRose and change the partitions with password protection I wasn't able to start Android ever again. It show this screen: enter image description here

I can access to the adb shell, and I can see all the private folders. So my question is

What folders/files do I need to backup to restore after the phone is fixed?

I know: /data/data

anything else?

Is there any output to adb logcat while the phone is on that screen? Can you still boot to Recovery or Bootloader? – Chahk Mar 15 '12 at 17:25
Hi I can see the device on the adb list but no logcat nor application is opened.. I can start bootloader and fastboot. But because of the password thing I cannot do anything in there. – SERPRO Mar 16 '12 at 10:03

Here are the locations you can try to back up:

/data/app/         --> location of APKs.
/data/app-private/ --> location of protected APKs.
/data/data/        --> location of app settings.

However, if you are trying to install ICS a complete wipe is most definitely required.

Generally, re-partitioning the internal memory should wipe its contents. I would try manually re-flashing Recovery, wiping the device completely (system, data, cache, and dalvik cache) and re-flashing the ROM. If you do manage to salvage any app data, I would highly recommend not restoring it on the new ROM, as that can lead to problems, especially if you are backing up to FAT/NTFS drive (Linux file permissions are lost.)

Thanks. I'll not install ICS.. I'm going to install again the same ROM I was using.. Thanks for your answer. – SERPRO Mar 16 '12 at 10:04
