[SIZE=+1]Q1: How do I root my LG Optimus 2x running a stock ROM? [/SIZE]

1.Using spyrosk’s AIO toolkit (option 3), OR

2.If you are on stock Gingerbread, you can use TyrmHansen’s method here

These methods also install a custom recovery (such as CWM/TWRP on your phone)
​

[SIZE=+1]Q2: How do I enter recovery mode?[/SIZE]

When your phone is powered off, hold volume down and power button together for a few seconds till the recovery mode shows up. Some ROMs also have a "Reboot into recovery" suboption in the "reboot" in the power menu.​

[SIZE=+1]Q3: How do I change my ROM (install a custom ROM)?[/SIZE]

First, check if the ROM is usable on the bootloader you are currently on(check next question), then download the ROM zip file. Check the ROM thread for further instructions and details like what needs to be wiped prior to flashing and then install it in recovery(select install zip from sd card on cwm or "install" button in twrp and select the rom file). If the developer recommends a full wipe prior to installation, format data partition(factory reset) and system partition in recovery first. In many cases, you need to flash Google apps package (gapps) separately. It is recommended to take a nandroid backup before flashing a new rom, to be able to recover a working system quickly, in the case of a problem like non-booting rom or user experience not satisfactory for you etc.​

[SIZE=+1]Q4: What’s with the bootloader thing? What care should I take regarding it?[/SIZE]

There are two bootloaders: old GB one, and new unlocked ICS one, one of which exists on your phone. As a user, all you need to worry about is that you flash a ROM made for the bootloader you are currently on​

[SIZE=+1]Q5: How can I determine which bootloader I am currently on?[/SIZE]

If at the very start of your phone’s boot, you see a black and white LG logo, you are on the old GB bootloader. If you see a color LG logo, you are on the new unlocked ICS bootloader. Look here for images​

[SIZE=+1]Q6: How can I change my bootloader? The ROM I want to use is not available for the bootloader I am currently on[/SIZE]

Use spyrosk’s AIO toolkit’s option 4. Read the toolkit’s guide first, and follow all the instructions carefully​

[SIZE=+1]Q7: Which bootloader would you suggest for me?[/SIZE]

There is no “best” or “worst” bootloader. Although some old bootloader ROMs need a minor workaround for fast charging, there is no major difference in the two bootloaders. Choose either one and flash an appropriate ROM.​

[SIZE=+1]Q8: How do I flash a kernel?[/SIZE]

Flashing a kernel follows a similar procedure as flashing a ROM. First, check if the kernel is usable on the bootloader and with the rom you are currently on, then download the kernel zip file and install in recovery. Check the kernel thread for further instructions and details​

[SIZE=+1]Q9: How do I fix the slow charging on my phone?[/SIZE]

Some old bootloader ROMs suffer from slow charging bug. As a workaround, switch off you phone, plug into charger, wait for battery animation to complete (~15 seconds) and then turn on your phone. It will charge at normal speed.​

[SIZE=+1]Q10: What is ADB?[/SIZE]

Read a useful post on ADB here​

[SIZE=+1]Q11: How can I help developers make a ROM/kernel better?[/SIZE]

Firstly, remember that developers are doing voluntary work, so please do not demand anything from them or keep bugging them about something. Search around in the thread if your query/bug has already been answered/stated by someone. If not, bug reports are best supported with logs, or at least a procedure to reproduce the bug. Without these, it makes it hard(sometimes impossible) for a developer to solve it.​

[SIZE=+1]Q12: How can I provider a developer with useful logs to report my bug or give feedback on a test version?[/SIZE]

Read tonyp’s guide on how to get useful logs​

[SIZE=+1]Q13: My phone has a terrible battery life. How can I improve it?[/SIZE]

Check in your battery settings for the app(s) which is draining your battery. There may be an app which keeps your phone from sleeping and thus decrease battery life. Overclocking also reduces battery life. Also remember that after a long usage period(many months, or years), a phone’s battery usually wears out and its battery life may start decreasing.​

[SIZE=+1]Q14: Where can I find a list of all the latest ROMs, kernels and guides for this phone?[/SIZE]

In this thread​

[SIZE=+1]Q15: I am using a ICS/JB ROM. Network works fine, but my "baseband" or “RIL” is shown as “unknown”. Anything to worry about?[/SIZE]

No. Just leave the default RIL as it is on ICS/JB ROMs, don’t try to play around with it.​

[SIZE=+1]Q16: How do I change my baseband?[/SIZE]

All the info you need is in this thread here by tonyp.​
