v2.3.5a

- Some of the Google apps/framework files seem to be broken somehow. Replaced them with older version that seem to work. Update from GooglePlay if you need. Will try to update them in the rom, but for now this should be fine.

————————————-

- Updated Russian, Polish and Hungarian (approx 95%) – new version of IdeaFriend is not translated
- Updated Italian, Spanish, German and Portuguese here and there
- Updated GoogleApps and GravityBox
- Update kernel to S150
- Optimized png files in almost all apps
- Revised scripts and replaced sqlite3 binary with faster one
- Scrolling in lists and animations should be smoother
- Deleted line in build.prop that disables JIT compiler. If anyone need it can always add it again.

- Fix quick boot nad charging when phone is off
- Removed 'Unknown city' text from ideaFriend call log

- Modify autobrightness

- Fix problem with some GPS tracking apps

As always make a full nandroid backup first!

Update script clears dalvik cache, but does not delete user settings.

- Fixed Network modes

- Modified email client startup/new account screen
- Changed default wallpapers
- Attempt to increase sdcard speed
- Updated adblocking hosts (for those who use custom hosts file – backup it manually, because I forgot to make a backup from the script)
- Fixed ideaFriend messages grouping. In order to activate the fix, you need to remove all current message threads, then go to Settings -> Apps -> ideaFriend -> Delete Cache and restart phone. Then you can try to restore the messages from the backup and see if it will still work (not tested with restore).

As always make a full nandroid backup first!

Update script clears dalvik cache, but does not delete user settings.

Due to several request, this flashable CWM zip updates v2.2.1 to v.2.3.1.

User settings and installed aps should stay in tact, but keep in mind there might be some mistakes. I tried to include all changes.

Tested with clean installation 2.2 -> 2.2.1 -> 2.3.1, so there's always possibilty it doesn't work for you with all installed apps.

As always make a full nandroid backup first!

Update from V2.2 to 2.2.1 (Patch)

- Fixed* callerId matching issues, however it's adjusted for Bulgarian GSM numbers, so it might not work in your country. Credits to C3C076 from xda!
- Chinese city names removed from contacts and call logs – not displayed anymore
- Fixed problem with initialization of Sony Clear Audio in config files
- Standard launcher modified, theme is removed. All needed icons/styles are encapsulated in the launcher.
- Added two additional and helpful options in power menu – Reboot and Recovery
- Boot/shutdown animations changed to Lenovo

* You will need to manually remove all contacts and import them again in order to activate the fix. Also remove all message threads. After that new ones will be grouped correctly
 Update script tries to keep all user settings, so your launcher screens and wallpaper should be preserved. However, if you flash the update over a fresh V2.2, you will still need to remove the lotus and missing widgets from launcher screens, then change the background if you want. As always, make a full backup, just in case. Script wipes cache partition and dalvik-cache, so first boot will take time. I will address other issues in future version, but it might take longer time to release it. So far updates were very frequent, but as the ROM gets mature enough, it doesn't require many changes. Please report any problems you encounter, they are taken into account.
