Root Your Android G1 with RC30 firmware!

It has been prophesized for weeks now, but it is finally here. A rollback method for RC30 users who want root. This method is a full device flash that will roll you back to RC29 which still has the root bug. After doing this you can then follow the instructions on Rooting Android and then Keeping Root to get yourself up to RC30 modified version that lets you keep root.


You will need the .nbh file to perform this. It can be downloaded here: (download on your pc) or DREAIMG.nbh (download on your G1)

MD5 Checksum: 53840b90a0fe1bfab19fab8ef8fb9724 DREAIMG.nbh


Please use a mirror first if you can (users downloading on the G1 should use the above links).

Mirrors for the .zip file: Megaupload or koushikduttas site or RapidShare

  4. Hold Camera button, and press Power button to entry Boot loader mode
  5. Press Power button to start upgrade procedure
  6. After finish, perform the soft reset to reboot.

When you are done, do not forget to follow the steps Rooting Android and then Keeping Root


  1. Just tried this and the update failed. Now I'm trying to get my G1 working again, as it won't boot. Also, I found a thread on the xda-developers forum that shows people having this same problem. Somebody got the update properly flashed, but others didn't. Either way, the website is giving some error now so the only way to see it is through google cache or something similar.

    If anybody has ideas about reflashing to a different working firmware, let me know. BTW, I can still get in to the flashing mode (holding the camera button). It comes up automaticly now.

  2. I would think that if you are going to copy the EXACT contents of my wiki page you would at least link back to the wiki you obtained your information from.

    I do not mind reposting information on other sites, but when I do it I try a: to rephrase it, b: to give the original author credit and c: link back to the original source.
