Guest jmr144k Posted October 25, 2010 Report Posted October 25, 2010 I was attempting to downgrade from 2.2 v1 to 1.6 build 6601.While following "Guide to Upgrading and Downgrading the Streak" • Downgrade from Stephen Hyde's 2.2 to O2 2.1 (build 8105) & Downgrade from O2 2.1 (build 8105) to O2 1.6 (build 4399) then to AT&T 1.6 (build 6601) with Baseband Downgrade I was having perfect success until I reached the last section: If you just wanted to revert to O2 1.6 (build 4399) then you are done. If you are going to AT&T 1.6 (build 6601) we have to change the system so it will upgrade the the AT&T ROM. 1.Download the official AT&T 1.6 (build 6601) ROM from here. 2.Rename the file to Update.pkg and copy it over the old file in the root of your SD Card. 3.Download this boot.img file from here and place it in your fastboot.exe folder. 4.Download this file and unzip it. Take the three files out and put them on the root of your SD Card. 5.Use Universal Androot (download information seen above) to gain root so you can use Root Explorer to copy files to the phones internal storage in the next step. 6.Use Root Explorer from the market to then mount the /system partition with r/w permissions. The first time you run Root Explorer it will ask for superuser permissions, click Allow and then copy recovery-from-boot.p from /sdcard to /system, copy install-recovery.sh from /sdcard to /system/etc, and copy applypatch from /sdcard to /system/bin 7.Put your Streak into fastboot mode. 8.From command line type: fastboot -i 0x413c flash boot boot.img 9.Then type: fastboot -i 0x413c reboot 10.Once it has booted fully into the Android OS shut it down and go into recovery mode. 11.In recovery select Software upgrade via Update.pkg on SD Card using volume keys and camera button to select. Be patient it will take a while. 12.The Streak will reboot and you are now on AT&T 1.6 (build 6601) with the Stock Baseband. I followed these steps precisely but when I reached step 9, my reboot never got past the "Dell" logo. It is hung and I cannot recover. I have repeated steps 7, 8 and nine but I still get hungup on the "Dell" logo. :P Can anyone help me?
