I have had my Optimus 2x since May and there have always been some problems, that's a well-known fact.
This week, I used the KDZ Flash method to update to the official (stock) v20L release from LG.
It seems a bit faster, the front cam works, but I'm (still) experiencing the following issues:
- GPS issues (new in 20L, not in 10D)
When using GPS, the GPS icon flashes until it has a fix. However, often the GPS icon then disappears completely.
I have to reboot the device to get it working again. This problem is random, it can also occur after a fresh boot.
This is a major issue for me.
- Performance issues (present since 10B, better in 20L but still present)
After the phone's been on for a day or so, mainly video/audio and games start to stutter and have micro-freezes. Youtube seems to be the worst.
- 3G disconnects (new in 20L)
When the phone is standby for several hours, 3G seems to get disconnected. When I turn on the screen, the network signal bar is white, indication no 3G. After a few seconds, 3G reconnects itself. Then the battery drains itself real-time: you can see the percentage running back. About 1% per 30-40 seconds.
You have to reboot quickly then to stop this and still have some battery left. Also, the fact that 3G is disabled is annoying since you don't get a lot of notifications from programs.
I have several questions now:
Are any of these issues fixed in the GR5 version Paul is going to release next week, or are any other fixes known for these issues?
How can I 'upgrade' from the stock 20L to the GR5 release? I have been looking and searching everywhere, but I can only seem to find bits and pieces of info.
I guess I need to root the device first (is this already possible on stock 20L? If not, can I KDZ-flash back to 10D), then install some version of Clockwork and then somehow flash the GR5? Any more information or pointers would be greatly appreciated. I do have expert PC/tech knowledge but the whole phone-flashing is new to me.
I am of course more than willing to upgrade to a paid account if any of these issues will be resolved and/or flashing this rom over stock 20L is at all possible.
Thanks for any help and also thanks to Paul and people like him for trying to give us a usable P990.
