Q1: How do I root/unlock this phone?
There is a guide in the 'General" subforum. Recoveries can be found in the 'Development' subforum.Q2: What is the best ROM?
Note: There is an " Everything" thread stickied in the 'General' subforum where you will find many of the goods for this device.
Please refrain from asking questions about the 'best' ROM, kernel, launcher or anything else as the answer is subjective at best. Here is a reply from a Moderator Best/Fastest RomQ3: Do I need to do anything besides root/unlock before flashing a ROM?
Make a backup of your current ROM.Q4: After flashing a ROM I am stuck on splash/boot screen- what do I do?
Try wiping data, cache,and dalvik as well as under mounts and storage format system then reflash. If you still have the issue go to the ROM specific thread and search there for an answer. If you have searched and the answer is not there then post the question, preferably in 'Q&A' subforum rather than the development thread.Q5: I changed to a different recovery- where is my backup?
It can not be seen by a different recovery - either revert back to the recovery where your backup is located or make a new backup with the recovery you are now using.Q6: How do I return to stock?
LGNPST. There is a guide in the 'General' subforum.Q7: Why is my 'XYZ' app not working on this new ROM?
This is most likely not because it is a new rom. Best solution is to uninstall the app and do a fresh install, meaning not from a backup.Q8: Why is battery life not so good on my phone?
We all use our phones a little to a lot different than someone else therefore there is not a 'one fix' answer. Try using a couple of apps such as CPU Spy and Better Battery Stats to help you identify the problem areas.Q9: After flashing a rom, I get a pop-up saying ' Unfortunately the process Android.process.media has stopped. How can I clear that message?
Clear Data in media storage is usually all it takes. You may also re-flash the rom- when re-installing apps do not restore data.Q10: MTP connection for my phone is on. Why doesn't my pc/laptop recognize it?
Try a different USB port and / or cable- try rebooting the computer (up to 3 times). Try USB port that is 2.0 rather than 3.0.Some Win 8 users report issues, consult Win 8 support. Uninstall and then re-install the LG drivers from Here
