My Droid is still running 2.0.1 rooted, with SPS Recovery, just as it was the week the 2.0.1 update was pushed out OTA - I’d already rooted it, disabled OTA updates, and performed a simple procedure to update and keep root.
My one complaint is that - as always happens with a new and cool technology that gets widely adopted - it seems like the Android community is being, well, dumbed down. When I first rooted my Droid, it involved using the adb shell. Now, it’s hard to find instructions that aren’t written exclusively for Windows - or even instructions that actually explain what I’m supposed to be doing or why it works.
I know that I haven’t followed the Android world much lately, but it seems to me that this should be really simple. The update.zip OTA updates are just patches. I already have the device rooted on 2.0.1, have disabled OTA updates, etc. So it seems to me that I should be able to just unzip the update file, change whatever needs to be changed to keep root, re-zip it, and upload it. If it wasn’t already done (the HowTo that I followed to update to rooted 2.0.1 doesn’t seem to be online anymore, and I can’t find the URL), I should be able to just change the update verification keys to accept anything.
Well, I guess it’s time to continue my hours of research and see if I can come up with anything. Everything I’ve already found says that I have to backup all of my apps and data and just flash a new ROM, but that seems stupid. Why can’t I just make use of this wonderful patch-based updating and keep root?
