[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.
