I know a lot of the senior members are getting fed up with having to answer the same questions over and over again. This forum is supposed to have a friendly atmosphere but when someone personally answers the same question 30+ times you start to lose your friendly outlook as well as your patience. That's why this is here, maybe it'll even be stickied.

First and foremost, this is a development forum, not Q&A. If you need to ask a question such as "how do i...", "what does...do/mean", etc go there. If you have a question about a specific aspect of a specific ROM, ask in the thread about it. If you have the ROM there will be a thread about it unless you just made it. Now onto the FAQ.

FAQ

Q. What is android?
A. Android is an OS for smartphones, more specifically it's a version of Linux. There are several versions to date and they all have names as well as version codes. The most recent (at the time of this post) are Froyo(2.2), Gingerbread(2.3), and Honeycomb(3.0).

Q. What is root?
A. Short answer: If you don't know, you don't need it. Long answer: root is equivalent in Linux to having administrator privileges in Windows. It allows you to change more system settings as well as run apps that need root access. It also allows you to flash custom ROMs as well as do a lot more. Root is for power users, not your average user. Can the average user benefit from root? yes but power users will benefit more. Root can also screw your phone if you don't know what you're doing.

Q. What is a ROM?
A. A ROM, simply put, is software for your phone. It's the main OS and usually includes other apps, tweaks, settings, and the like you don't normally find in a stock phone.

Q. Where do I get ROMs?
A. Look in the board for your specific phone.

Q. How do I flash a ROM?
A. First you need root. You also need some sort of custom recovery. I prefer clocwork so that's what I'll describe. Other recoveries should be similar. Reboot your phone into recovery, go to "Install zip from sdcard", pick "choose zip from sdcard", then pick the zip file containing your ROM. Allow it to flash, flash any other zips you may need (gapps, kernels, etc), then reboot your phone. Flashing a new ROM resets many aspects of the system so the first boot could take up to 5 minutes. It is also recommended to do a full wipe when flashing a ROM unless you're updating from an older version of the same ROM.

Q. How do I flash the GApps zip?
A. Same way you flash a ROM.

Q. How do I flash a kernel?
A. Same way you flash a ROM.

Q. How do I flash a radio?
A. There are a couple of ways. Some radios come in zip format, you can flash those the same way you flash a ROM. Some come in .img format, you need to flash those from fastboot (S-OFF required)

Q. Where do I get a radio?
A. Check the forum for your phone. MT3GS users look here

Q. What is S-OFF?
A. A security state for the phone. Having S-OFF allows people full root access to the phone, even when in the main OS. With this you can add/remove system apps without the need to boot into recovery or reboot after removal/addition.

Q. Do I need S-OFF?
A. Ask yourself these questions: Do I know what I'm doing? If yes next question. Do I want the latest/greatest thing? If yes next question. Can I recover my phone if I completely destroy my OS? If no then you don't need it. If yes next question. Can I recover my phone from a full brick, not a semi-brick and/or do I develop ROMs. If yes go ahead and get S-OFF.

Q. How do I get S-OFF?
A. Look in the forum for your specific phone. For MT3GS users see here. I suggest you read the last 10 pages or so before attempting so you don't ask a repeat question.

Q. My phone shows a red triangle, what do I do?
A. You're in stock recovery, press volume up+power to get the menu. Ignore the cache error.

Q. How do I get root?
A. See the forum for your specific phone. For MT3GS users see PC Method and the No-PC Method. They use the same exploit so they're very similar.

Q. What is a kernel?
A. A kernel is the core of a Linux OS, it's what all the other software is built around. No core/kernel, no OS. A custom kernel enables features that the stock kernel didn't have such as OCing.

Q. What does OC stand for?
A. Orange County. Just kidding :P OC stands for overclock, taking your phone's processor and making it run faster but work harder. It can cause stability issues and reduce your phone's lifespan so evaluate if you need it or not. Also make sure to test the boundaries your phone can handle. Some can go higher than others without issue.

Q. How do I get into recovery?
A. That's different for each phone. For MT3GS power off the phone, press volume down+power. You should boot into HBOOT, Press volume down to highlight recovery the press power to select. If your phone has Rom Manager with Clockwork installed you can also boot into clockwork directly by choosing "boot into recovery".

Q. (MT3GS Specific) I'm using alpharev's S-OFF and my phone freezes what do I do?
A. When it says to press "any key" press and hold power on your phone, then press any key on your keyboard.

Q. (MT3GS Specific) I can't get alpharev's to boot.
A. You either burned the image improperly, have a bad download, or don't have your BIOS setup to enable booting from removable media. Try the LiveUSB version posted in the thread (one by me and one by another user).

Q. (MT3GS Specific) In the PC method you posted I can't find the files! Help!
A. There are links to the files in the No-PC method. They'll work.

Q. What is "cooking" a ROM?
A. Building a ROM from source is usually referred to as "cooking" a ROM, but sometimes cooking can also mean rebuilding a themed ROM.

Q. Where can I find a good android kitchen?
A. Search XDA, search is your friend.

Q. What is a "kitchen"?
A. The kitchen is the environment that is used to build a ROM.

Q. How do I cook a ROM?
A. That depends on your kitchen, it should come with instructions.

Q. Does this count as development?
A. I think so. It discusses flashing custom ROMs, gaining root, cooking, theming, recovery menus, and the like.

Q. Android Rocks!
A. Yes, yes it does.

Q. How do I install a custom boot animation?
A. Move the bootanimation.zip file to /data/local on your android device.

Q. How do I install custom boot sounds?
A. Move the android_audio.mp3 file to /data/local on your android device.

Q. What's the best ROM? (thanks to SefEXE)
A. Short Answer: Check the ROM Bible for your phone. Slide ROM Bible Long Answer: There is no best ROM, only ROMs that are best for you. Look through the different ROMs and see which one fits your needs the best.

Q. My phone isn't seen in recovery in the loop, help!
A. That method is old. That's why I didn't link to it, it no longer works.

Q. My phone is in a boot-loop, what do I do?
A. Give it 5-10 restarts, if it hasn't booted into your OS by then it's probably not going to so you need to reflash your ROM. (expanded on by fermunky) Try removing the SD card to eliminate something on it being the culprit. Next, if this was after trying to install a custom ROM, either try to re-install it, or if all else fails, do a wipe and re-install. This assumes you are able to get into fastboot/hboot/recovery from a boot loop.

Q. Do I need S-OFF to get root?
A. -_- no. You need root to get S-OFF.

Q. Do I need S-OFF for X?
A. You only need S-OFF for changing the /system partition while booted in android, flashing things through fastboot (splash screens,radios, etc), and custom MTD partition sizes.

Q. How do I install flash/does flash work?
A. Flash isn't supported on our phones, it's a hardware limitation. Use the flash lite plugin.

Q. How do I revert to stock after rooting?
A. That depends on your phone, you may be able to just flash a stock ROM it may be a little more involved than that. MT3GS users look here.

Q. I can't find the marketplace after installing a custom ROM.
A. Custom ROMs are not allowed to have the market pre-installed. You must download the latest gapps zip file and flash it.

Q. What is a2sd/app2sd?
A. It is a mod for ROMs that allows installing apps to your sdcard. Some ROMs have this built in by default so check before looking to install it.

Q. What is a2ext?
A. Similar to a2sd it allows you to install apps on your sdcard but uses a Linux ext partition instead of a FAT/FAT32 partition.

Q. How do I find my Radio version?
A. This can normally be found in the HBOOT/FASTBOOT screen of your android device. Getting to this screen depends on your device so the methods vary.

Q. How do I find my Android version?
A. Go into settings, scroll down to "About Phone", then look at "Android version".

Q. Should any ROM work with the newest Radio?
A. Yes, the Radio should offer many improvements over the old one and not cause any stability issues. You will, however, want to flash the latest released radio and unroot before returning your device for servicing. The latest Radio is not always the latest released Radio.

Q. I have a question about CM7.
A. Go here. Some things are repeated from here, others are not.

Question
Please answer in your FAQ:

Q. What is apps2sd? A2sd? Apps2ext? Apps2fat?

(I don't know all the names, use your smarts to create the question and the answer for your FAQ!)

I am a noob and these terms are confusing to me, what is fat and ext, also is a2sd just abbreviation of apps2sd? That type of thing.

Q. How do I find my radio version? How do I find my Android OS version?

Q. Should I be able to flash the newest radio while using any ROM?

Can't think of any more right now for ya to add.

This is supposed to be to answer the questions that drive everyone insane because they have been answered a million times already. The a2sd question fits that but the others don't. You know the saying though, an ounce of prevention... I'll add out of the dozen or so potential questions there the ones I feel are most important. As for FAT/FAT32/EXT/NTFS, that's what google is for. This does assume you have some basic computer knowledge but little to no Linux experience. I'll answer those questions for you in a PM but right now I don't see a reason to add them to the FAQ. If they come up more I'll add them then.

Let's say I was on CyanogenMod 6.1.1 and I wanted to update to CyanogenMod 7 without losing any of my data. Is there any way to update to a newer version of a rom without having to wipe data through Rom Manager or ClockworkMod?

Just don't do a wipe? It could cause issues so it's normally recommended you do a wipe from one rom to another (cm6 and cm7 count as different roms) but not between rom updates (cm7 rc3 and cm7 rc4 would be updates and you wouldn't need to flash). It's not really a question that's asked a lot so I'm not going to add it to the guide but yeah, you can always try without a wipe,but always do a backup just in case.

OK, so this is my 4th Android phone (G1, Cliq, Optimus T, & now mT3GS). I have been around many large dev groups... Im happy to see a couple of them working on multiple phones I have purchased (and not known to me prior), including dated first gen Android phones STILL! However now to the point (and to stay on point), This is one of the best FAQ's I have ever seen... on any forum, phones, computers, blogs.

I want to add my name to the Thanks but I cant find the damn button... lol

So.... Thanks from me, all the noobs, and for all the seasoned android users that think FAQ don't apply to them, but should read... due to the great writing.

You might notice I have been an XDA member since 2008, and this was the most compelling information I felt to make my first post.

I got a request and I hope everyone will help me.

XDA censored htcclay. This isn't about religion, politics, or what you believe/don't believe. This is about how XDA censored a member for a non-offensive signature (he put "Jesus Christ is my Lord and Savior") The signature didn't target anyone, it didn't insult anyone, it just said what he believed and he didn't force it down anyone's throat.

All I ask is for everyone to go to RootzWiki and make an account there. We need to setup a myTouch 3G slide section in the forum and post ROMs.

I hope you guys will join me.
