How To Upgrade LG GT540 running Mur4ik's Gingerbread 2.3.3 Without Loosing Data/Settings/Apps
Using Recovery Method: You need to extract the zip. Then install the extracted zip file from the SD card in recovery mode. (Full credits go to fishears for this method)
Using Fastboot Method: Use the "fastboot flash system system.img" command (without the "). You can do a backup afterwards in recovery mode.
You can extract it with root explorer on your phone. However, if you encounter system errors then, try using suggested backup apps mentioned below.
How To Backup Your LG GT540 running Mur4ik's Gingerbread 2.3.3
For those who prefer to do a clean wipe of their systems first before upgrading (in case of errors) fdespotovski & mircea89fzr have suggested using Titanium & MyBackup (rooted) apps. After upgrade, reinstall your chosen app & run restore to restore all previously backed up data/apps/settings

For all those having battery issues, I have been following all the comments & tips about it on this forum & I have been doing some experimenting over the last few months. And finally I have a working solution which has been working for me (see screenshot of my phone), it's been working now for 53hrs now & still at 45%. And I have been using the wireless at btw 4-6hrs per day & some long calls.
Here's what to do:1. Drain your battery totally, put it on & off until it's totally drained (screen refuses to come on)
2. Charge it over night (a good 4-6 hours). It might also be good to unplug and re-plug a couple of times if it reaches 100% prematurely.
3. Once the specified time has elapsed, without unplugging the phone from charge, go into (clockwork) recovery (from your reboot screen), go to advanced and, wipe your battery stats, then reboot. Once you click reboot, unplug your phone. And that's it!
Things to note: you must have one of the newer versions(versions 3+) of clockwork to go into recovery from full charge. I hope this is helpful & compliments Mur4ik great work & Joost's wonderful thread :)
