[Q] Unable to roll back to 1.6 ROM on UK/O2 Streak (21) - is it possible?

---

Has anybody with a UK/O2 Streak (21) been able to roll back from the stock 2.1 (installed successfully) update to stock 1.6?

I have searched xda and modaco for days and have tried everything but I always get stuck at the same spot.

I am able to flash stock recovery but when I use option 2 to apply update.pkg from my sd card, it gets stuck about 1/4 of the way and says "Software is up to date. System will reboot in 30 seconds." And then when it reboots, it's still at 2.1.

I have also tried using clockworkmod recovery (several versions), which only seems to work immediately after I flash it (sometimes clockwork menu won't show up and it reverts back to stock recovery - are they being flashed to different partitions or something?). Using clockwork, I tried to apply update.pkg and when that didn't work I tried update.zip. Both get stuck on black screen.

I have tried using ROM Manager too, but that never works. It says it will reboot into recovery but ends up just rebooting normally back into 2.1.

I tried stock and custom 1.6 ROMs with no success.

Is there a way to force the system to apply the update.pkg even if it thinks it is already up to date?

Any help would be greatly appreciated. I have been pulling my hair out over this for days. Thanks in advance.

I am having the same exact issue as described above. "Software is up to date."

And then the device just reboots into 2.1 and starts the cycle of endless reboots.

Anyone got a solution for this?

Please help.

The guides in the stickeys do work I have gone from 21 back to 16 and back to 21 about 6 times

Sent from my Dell Streak using XDA App

Yeah but all the methods in the stickies need the use of a PC. I am on a Mac. Is there a way to use fastboot on a mac? Or a way where I can just copy the update.pkg on my sd card and use that directly?

When I use the SD card method, 1.6 refuses to install saying that the "Software is up to date."

Thats what I need help with.

It lists mac commands to load the recovery image to your phone.


MAC - Open a terminal window to the directory containing the files, and type 'chmod +x install-recovery-mac.sh' followed by './install-recovery-mac.sh'

Yeah I tried those commands but I get a "No such file or directory" message in Terminal. I have read a lot of threads here and over at Modaco but can not make head or tail of the issue or what to do.

I have a O2 Streak that I had put 2.1 from O2's official release using the Recovery mode and putting update.pkg on SD card. After that I have been having a ton of issues with constant reboots and sometimes getting stuck on Dell logo.

I wanted to go back to stock 1.6 and have been unable to do so. What are my options right now and how can I fix this? I would prefer to keep 2.1 but don't mind going back to 1.6 if that will be more stable.

Sorry if i am incorrect about this.

As far as i can tell you want to stay with offical roms due to warranty.

I have heard that if you go back to 1.6 even though official, dell wont cover the warranty.

If you are not worried about try :-

The leaked 2.1 rom. I hear it is more stable than 02's 2.1 rom.

Or even go for stephen Hydes brilliant 2.2 roms.

I don't care about official or unofficial. I'll try loading one of the other roms. MY issues have been with getting the rom on the device though. Lets see.
