Updated for FRG83G. Due to the way the system is currently handling OTA's, there are now a few additional steps, but this will still get you to the most up to date version of stock Android 2.2.2 (FRG83G), in the purest way possible, without having to connect to a computer.
MAKE SURE YOU HAVE AT LEAST A 70% CHARGE ON YOUR BATTERY BEFORE DOING THIS (ESPECIALLY IF YOU WON'T BE CONNECTING TO A COMPUTER AT ALL)
*THIS IS FOR THE ORIGINAL MOTOROLA DROID 1 ONLY*
What's the point of this? I'm posting this as a simpler method to unrooting and reverting back to the latest pure stock Android 2.2.2 build (FRG83G). The benefits of this method:
- if done right, you never have to connect to a computer
- you don't need to use RSD Lite (especially beneficial for Mac/Linux users, or those with 64 bit Win7)
- you simply want an easy/backup method to unroot/revert to stock, all with a couple of files sitting on your SD Card
If, for whatever reason, this does not work, please see this thread: SBF to root and to unroot . That .sbf method will work perfectly, and is an awesome tutorial, but is more time consuming, and has more moving parts to coordinate, so I like to think of it as more of a "last resort" and/or failsafe, if this method doesn't work.
Teddyearp has also put together a much more in depth and thorough description and tutorial on this same subject here - he knows about 1000x more than me on all of this: How to unroot your phone-complete
Christim's instructions (the "SBF to Root and Unroot" linked above) also include a basic set of instructions for this method in Box Option 06.
Those are both awesome, I simply wanted to do my own set of instructions that followed the way my brain works.
Note: If you are already familiar with using custom recoveries and flashing custom ROMs, you likely don't need this tutorial. Just know that the FRG22D Master OTA file can be flashed just like any other custom ROM (in a custom recovery only), and it will replace your custom recovery, ensure you're on the latest bootloader and baseband, and obviously replace your /system with FRG22D's system. Currently (as of 3/19/11) my phone receives both FRG83D and FRG83G automatically via OTA after flashing the FRG22D file, so nothing more really needs to be done besides that. If you're returning the phone, it's probably a good idea to go ahead and wipe data/cache before flashing FRG22D.
If you won't be able to connect to a computer, and will be doing 100% of this on your phone...
- You will need a file manager, such as Astro, off of the Android market.
- When you download any files from this thread, it should go into your /download directory on your SD Card. You'll need to move the from that directory to the root (base directory) of your SD Card.
You will need two files - the FRG22D Master OTA file and FRG83G Patch OTA file
- FRG22D Master OTA: click here
- FRG83G Patch OTA [update: you might not need this... since I updated this thread, my phone is now receiving both FRG83D and FRG83G via OTA, in succession - but still good to have it]: click here
- Once the files are downloaded, place them on the root (base directory) of your SD Card and make sure there are no other files titled "update.zip" on the root of your SD Card. Do NOT rename these files yet - instructions below will specify how/when/why to rename them.
Determine which recovery "program" you have...
There are 4 recovery "programs" that we have available on our Droid 1's: RZRecovery, Clockwork Recovery, SPRecovery, and the stock recovery that comes with the phone. All four have a slightly different set of instructions for installing a .zip file, so I'm going to break it down with those four "programs" in mind.
If for some reason you don't know which recovery "program" you have, here's how you can test...
Power off your phone. Then, hold down the 'x' key on your keyboard and power it back on while holding down the 'x' key the whole time.
If you see a black background with a blue menu on top and white text on the bottom, you have RZRecovery. RZRecovery can have different colors, but this is the base look upon initial install.

If you see a black background with mostly green or light green text, you have Clockwork Recovery. Example (old image - text/version is different, but look is the same):
If you see a black background with a puke-green Android, blue text at the top, and orange text in the middle, you have SPRecovery. Example:

If you see a triangle with an exclamation point in the middle, you have stock recovery. Example:

Once you know which recovery "program" you're using, you can skip to the appropriate set of instructions in the next post.
