This guide is awesome!! thanks so much for making it homeiss! I just upgraded last night from stock Donut to O2 Donut to Dell's Froyo! and I'm loving it! to anyone having problems with Root Explorer, I had to buy the full version ($4, small price to pay for froyo goodness) in order to get the read/write functionality and then I just copied the individual files in each of the folders from homeiss' zip to their respective folders on the phone's memory. worked like a charm!

Now, I'm on O2 2.1 with baseband 21. I try to start upgrade to 2.2 by didn't back to 1.6.

I start at step 10, but I can't copy files to /etc and /system directory. I continued till step 14 and reboot. After reboot I stuck on dell logo.

I try to go to FastBoot mode but stuck on "Wait for USB FastBoot detect..."

How I can get my OS back? Please help

This guide will assume you're running O2 1.6 (build 4399). If you're not, then go to my other guide here and follow it to either go from AT&T 1.6 (build 6601) to O2 1.6 (build 4399), or to downgrade from DJ_Steve's ROM or from O2 2.1 (build 8105) to O2 1.6 (build 4399).

To get the Dell Official upgrade.pkg to install you must be running the 00 Baseband.

• Download this zip file which contains a recovery for downgrading here.
  
• Move the recovery.img file to wherever your fastboot.exe is.
  
• Put your Streak into fastboot mode.
  
• Open up command line type: fastboot -i 0x413c flash recovery recovery.stock.new.img
  
• Once it says it's done writing type: fastboot -i 0x413c reboot in command line.
  
• Root your Streak using Universal Androot found here (you will ptobably have to click "Go Root" twice to get it to work).
  
• Now download RootExplorer from the Market.
  
• Download Official 1.6 (6267 Build) from here.
  
• Rename the file to Update.pkg and copy it to the root of your SD Card.
  
• Dowload this file and put it on the root of your SD Card.
  
• Download this file and unzip it to your SD Card.
  
• In RootExplorer click the Mount r/w button at the top. Then copy the files you unzipped to the same place on the Streak (etc to /etc, system to /system).
  
• Now download a Terminal Emulator app and type: su
  
• This will give you superuser abilities and then type: flash_image boot /sdcard/boot.img
  
• Reboot your Streak and let it boot back into Android.
  
• Reboot your Streak While holding the volume keys down and then apply the update from sdcard.
  
• It will take a while to install and boot.
  
• Download the newest build of the "Official Dell 2.2" from here.
  
• Rename the file to Update.pkg and copy it to the root of your SD Card.
  
• Reboot your Streak While holding the volume keys down and then apply the update from sdcard.
  
• Again, it will take a while to install and reboot, but when it does you should be running Dell's 2.2 (11548 Build) with the 00 Baseband.

Thanks a lot for the tips. I am searching for something just like this. However, I have a slightly different experience.

I upgraded my dell streak to Honeycomb but found it has power management problem, which makes it undesirable. Then I downgraded it to Froyo following the instruction given below, and found that this is a T-mobile version.

Actually, all I want is to restore it to dell's official version (my streak is independent from mobile companies). Would I be able to do that following your instruction?  

I'll be grateful if you can help me with this question. Thanks in advance.
