I've been using gingerbread for two days and scared by the battery problem, I decided to fall back to froyo. Here's what I did:
1)JSD flash (with PIT/re-partition)
2)Speedmod kernel flash
3)Turned everything I could to ext4 from recovery
After this, I recognized that some apps in the market are missing, such as Fancy Widget, Launcher Pro, Titanium Backup, Watchdog etc. These were some of the applications installed on my phone before. However, some other items installed on my former system were there, such as Battery Status Bar, Digital Rain, Andoku, etc. I'm not talking about "My Apps", I'm talking about searching and not finding. Then;
4)Flashed JPO (with re-partition/PIT)
5)Flashed fugu root
6)Flashed original kernel back
The market situation was the same;
7)"Uninstalled the Updates" and "Cleared the Cache" of the Market from Settings/Application Manager.
8)Cleared cache and did factory reset/clear user data
9)Applied "fix.apk" from jrummy
11)Fugu root/flashed JPH kernel back
Frustratingly, none of this worked. I would very much appreciate your help, thanks in advance.
