[Q] Newbie Terms - myTouch 4G Q&A, Help & Troubleshooting

I've tried searching but I've had trouble finding specific definitions as to what these terms mean and how to perform these functions.
I was reading a thread about Ice Cream Sandwich because I want to upgrade my myTouch 4G from 2.3.4 to 4.0.1. The thread entitled [ROM]MIUIce Cream Sandwich [Android4.0.1 + MIUI Hybrid][UPDATE 11/12/11] (sorry, I can't post links yet) has instructions that say: "Wipe user Data and /system. Flash ROM. Eat cookie. Play a song of accomplishment and enjoy."
My questions are - does wiping user data basically mean backing up and clearing the phone? What does a "/system" procedure mean? And what is flashing?
Do I need to root my phone before I perform this procedure? I'm sorry for all of these annoying questions. I consider myself rather tech savvy outside of phones, so my ignorance is putting me to shame right now.

1) i would HIGHLY suggest taking some more time and reading before you do anything else. The questions you are asking are extremely basic. like the before the baby learns how to stumble around in a walking motion. Look at my "newbie thread" [link in my signature]
2) Yes your phone needs to be rooted prior to doing anything.
3) wiping the /system means wiping the /system partition section of your phone. YES you need to back this up prior to wiping it, incase you want to come back it.

you need to do some SERIOUS reading and learning before proceeding... not knowing what you're doing to your phone can lead you to HUGE trouble.
it's not hard to learn though

If you're looking for Ice Cream Sandwich, you're looking in the wrong direction. All the ICS changes for MIUI are "under the hood", and it's written in bold letters in the first post of the thread. You won't see any visual sign of ICS, it's just a regular MIUI.

I have an idea i would like to share with everyone.. and in fact this very post is the first action i am taking toward making this idea a reality. I am starting a post for teaching, for helping people understand the basic rules behind the fascinate. IF this works well it can then be applied XDA wide. I need everyone possible to contribute to this post. Your job is to keep returning here and teaching me by answering questions.. My job is to over analyze and repost questions..
the biggest reason i am doing this is because nothing on these forums is linear. by that i mean their is no start and end or set direction to help new people get a general understanding in this community. I myself look for answers to to a question among the vasts posts, and instead of answering my initial question i pose 10 more questions to myself.. i then Google some things.. get lost in tabs.. and post dumb questions that flamers are just waiting to jump on.
i will make this OP a living post.. i will continually edit it adding definitions, generalizations and basic rules i gather from your replies and our discussions.
SO, to start this out. i would like to have people post small things you have noticed that help a large amount of people, things that newbies question the most and things people should know in general to understand some of the language the more adept people use.
ps.. im not talking about the newbies that dont bother to read the beginner sticky
If you want to flash froyo, you should flash jt1134's latest clockwork patch first. CWR is badly broken under froyo, and using fallingup's guide won't give you a useful recovery after DL09.
Most voodoo problems can be resolved by flashing a full odin recovery. Still, don't install voodoo unless you know why you want it. Some good reasons are a lot of file system lag like from massive email syncing etc. and kaos's CM alpha only world under voodoo kernels.
Actually the full recovery images fix most problems you can run into. Because of their usefulness and size, hosting them is burdensome - consider donating to the hoster out at least using a torrent if available.
You can use heimdall instead of odin. NEVER touch the [phone] button in the Odin user interface. If a flash fails, flash again - no point in rebooting a bad flash.
Manually rooting isn't very difficult. Do it at least once.
Learn the definitions of: kernel, modem/baseband/radio, and rom. Learn the difference between CWM and Odin, and how "flashing" works in each. I like to use the word install with zip roms and when using CWR in general to limit confusion, but both are capable of flashing images to your Fascinate's internal memory partitions.
Be comfortable with getting into both recovery and download mode before modifying your phone ib any way. Backup via nandroid and keep a folder of odin images on your computer and keep track of install.zips on your phone.
Watch out for update.zip getting overwritten, this should typically be clockwork recovery which installs temporarily to a RAM disk and then runs.
Be polite when posting, flames always generate a mess of useless posts.
Swyped w/ XDA App. When in doubt, mumble.
Know where to post. If you aren't actively developing something for the Fascinate, don't post a new thread in the development section. Even if you think your post is related to development, it most likely isn't, and belongs in the general section.
Read on voodoo before you actually install it. Like, study how to install, the benefits, how to disable and uninstall, and what to and not to flash with voodoo installed.
Don't feed the trolls, and feel free to ask questions, hopefully in the correct thread and/or section.
DONT FLASH STUFF FROM OTHER PHONES OR YOU WILL BRICK YOUR PHONE!

If you are serious about Android then be prepared to read - that is the one thing which will separate you from the average user.
To get you started you will need to know a few basics before you can start contributing to a community which has dedicated themselves in bringing better Operating Systems (Roms) to our phones. By knowing these basic steps you will be able to help iron out bugs from whatever Rom you have decided to keep on your phone and thus, improving your own user experience.
If you are completely new to this then you should read Glevitan's Starter Guide. It contains everything you need to know and it is a mandatory prerequisite before you can post in this thread seaking help.
Now that you have read and understood some of the terminology and how to recover from possible issues, you can root your phone with the A high-level DHD/Inspire manual S-OFF hack concept for advanced users [NOTE: The AAHK HAS BEEN RETIRED FOR NOOBS. IT IS FOR ADVANCE USERS ONLY. REFER TO THIS STICKY INSTEAD [How to] ROOT without the Hack Kit] Even if you do encounter issues, knowing the terminology, what you did and what went wrong will help communicating your issue so we can find a way to solve it. If you read the starter guide you should know that we don't recommend using HTC dev to unlock your bootloader. However, if you did go this route you can read this helpful guide: [NOOB] Flashing a custom ROM & getting it to boot IF bootloader is htcdev unlocked. And finally, our own resident and esteemed Glevitan is working on a tool to make it easier for you all. [ROOT] [TOOL] Easy Ace Root Tool
After having spent some time in the XDA threads reading a lot more than what you should post, you will have realized that almost any question you could possibly think about has already been asked over a dozen times and why so many emphasize the importance of searching for your answer first. You would also come to realize what are the benefits of setting up ADB. Among one of ADB (Android debug Bridge - [GUIDE] ADB - Usage, Tips, Tricks and More! and [GUIDE]ADB Workshop and Guide for everyone) uses is creating logcats. These logcats help developers finding what is causing a bug and how to fix it. This is a quick [Tutorial] How To Logcat. However, this quick tutorial will only help you get started. Keep in mind that apps like aLogcat or Catlog could shorten important output from the log. Another one: Learn to logcat like a Pro!
To be able to help developers create a better user experience for us, we need to create a bug report. The reason why we first need to search the forum is to avoid confusing the developer by cluttering the thread with repeated reports, of bugs and questions which as mentioned earlier, most likely have already been asked. To have a better understanding of the different instances we can create logs, then have a look at: [TUT]Report a bug I do believe this can not be emphasized enough and thus, what better way than reading it from existz own words.

INDEX
ABSTRACT
The present document pretends to guide the noobs and not so noobs in their flashing / modding / theming way. It covers what the team thought is the basic stuff you should be in knowledge of and may be the most helpful. Any suggestions about the contents or stuff that you think should be included are welcomed, just let us know.
Guide Index
1.Basic Stuff: In this section you will find the common language that is related to Android / HTC Ace devices. This is fundamental for you to understand how things work.
2.Rooting: THIS IS OUT OF SERVICE...CHECK THE UNLOCKING BOOTLOADER TOOL IN PARAGRAPH 4
3.Fixing a messed bootloader: You are not good at listening advices or reading for comprehension. You flashed a froyo RUU or hboot in your GB shipped device? Thank God attn1 was around. This is the Hboot fix for you. All credits go for the Hack Kit Channel devs. I have not done anything but put it here
4.HTCDEV tool: So far, this is the best and only way to do the flashing stuff....
5.Unrooting: In case you need to take your phone to the service centre or lost your mind and want the stock rom back (is there anybody that actually does? :cyclops ) you will find everything you need to know here.
6.Flashing roms: The right steps to flash successfully a custom rom…you can´t miss it. If you do, then you haven´t read carefully.
7.Doing / Restoring a nandroid backup: In case you mess it or you don't like what you get on a new rom, a nand backup is what will save your A**. Follow the path and you will see the light at the end of the tunnel.
8.Radio / RILs: All the radio / RILs related issues, follow this or you will regret it!!
9.Kernels: Everything you always wanted to know about kernels but you didn't dare to ask. Links on line now..:silly:
10.Trouble shooting: I guess this will be the most visited section of the guide. OF COURSE YOU DIDN´T READ THE ABOVE. NOW YOU ARE HERE BUDDY FIX YOURSELF A GOOD READ
11.Customization: For those who would like to start customizing your devices, here you will find a good point of start but THIS IS JUST THE BEGUINNING [/QUOTE]
12.Battery drain issues: I HAVE FLASHED A NEW ROM AND MY BATTERY IS DRAINING WAY TO FASSSSSST!. Well that could be normal, just read and learn before you run out of battery...lol
Find the document here: http://d-h.st/Ii2
FAQ & Notice
FAQ :
What Is the Best Battery,Performance GB/ICS/JB ROM?
There is no best ROM, the opinion of each ROM is different from one person to the other, it is subjective.
Is there a recommended Radio for ROM x?
There isn't a recommended radio for any ROM, since the Radio depends where you live, it is best to test each one for a few days to see which one works best for you.
Can I Flash RIL For AOSP ROM?
No, the RIL is sense based ROM,AOSP RIL is provided in the ROM
How Can I Boot in Recovery/Bootloader if My Volume Rocker is Broken?
You must setup adb and then the command:
adb reboot recovery/bootloader
Why Don't We Have Any OFFICIAL CM9 ROM?
Because the CM team always makes everything work (camera, camcorder, etc) and since we don't have the kernel 3.0 source, there isn't any OFFICIAL CM ROM from them.
Is There Any Official Rooted Sense 3.0 ROM?
Yes, There it is
Notice when Posting On the Dev Thread :
Please Read the First Post, It Usually Stated What's Working and Not Working
Don't Post Any THANKS, just use the thanks button
Don't Even Ask ETA of the ROM, the ROM will update when it's ready
Full Wipe Is Recommended when Updating the ROM, but also can try it without (this is basic,even if it's not stated on 1st post)
ADB is easy, very simple to use. Its the CLI interface that most cannot get used to and are afraid of.
A great XDA guide/overview on ADB here. --> [GUIDE] ADB - Usage, Tips, Tricks and More!
After a full wipe including sd card, to restore a backup mount sd card to pc, create the folder "clockworkmod/backup" place backup there - unmount, flash.
Is there a way to flash a backup using adb? If yes, do the folders need to be created or not and what would the command be? I couldn't find an answer for that.
Edit: Answer is no. Why? I have no clue.

@hdorius - what do you know to do? Didn't you port paranoidandroid? The faq's look good but needs some editing/correction. Where are you from? What's your first language? Do you need help with that?
@Guy - what happened buddy? In the previous page I suggested a few things. Apps? It depends what the others think. I don't see this as a standard.
@miukkuman - where are you?
By the way, where are you from? What do you know to do in the android world or what are you interested in learning?
@everyone - the idea behind this thread is:
- I rather ask each one of you to tell me what you understood which is the idea behind this thread - what you understood. If you didn't understand then I'll need to find a better way to explain myself.

ok, before sending the file via PM, I can answer you...there's no choice of restoring a backup from adb. That is the same as flashing a Custom Rom....those files are packed in a certain way that won't be possible to be flashed in hboot (PD98IMG.zip) way.

Thanks bub, so no can do. I don't believe in 'no can do's
Did you read my question about the hboot interface in the other thread? This, and the above question is simply a language (which I know absolutely nothing about) - there must be a way to get them talking to each other.

Anything you like really, it's your show. Porting? There are plenty guides for that. If you know any good ones I can link them in the third post. Can you look through the ones I posted to see which are good and if there are any ones that are repetitive or if there are better ones than the ones I posted? Especially the flashable zip link, since I don't know anything about that, maybe there is a betrer one or a guide or a tool for it?

Greets to all
Greets to all from another noob. Well, not a complete noob but a noob here on XDA given my few posts. My deep thanks for allowing a thread where sometimes there just might not be such a thing as a stupid question but honest ones instead,.... Hoping I can contribute something here as an owner of a softbank DHD here in Kyoto, Japan aka the 001HT. I spend alot of time trying to dig up general info from all over the i'net to help answer questions especially for ACE owners so I hope that might be of some help. Grant Barker's homepage is a great resource, (hope its allowed to mention that~). My first minor contribution------ 64GB MicroSD card usage with the DHD. It may already be well-known but for all us noobs who aren't too sure make no mistake..... I have the SanDisk Class 10 64GB MicroSD card and it works flawlessly in my DHD. Since I like to pack lots of MP3's and several full-length HD movies into my handset (helps keep the kids quiet on long drives ) being able to have that much storage space is a blessing! So, just to reiterate, 64GB microSD card--- no problems!

Thanks for the feedback Blashpemer666, hopefully you manage to refrain yourself in front of the kids.
Absolutely, we were all noobs, still are and probably remain being noobs. There is too much information to cover and too little time to do it in. We here are just trying to return to the community what they have given us by helping the new members whenever they need it and whenever we can, to the best of our knowledge, by pointing them in the right direction. Any and all suggestions are welcome.

[Q] Is Nexus 4 good for development?

I am new to Android development and going to do some system level development, e.g. kernel driver, custom ROM and etc, and looking for a new device to replace my old 2.2 one.
Nexus 4 is good to me since it's cheap and runs Android 4.x. However it does not have an SD card. So in case of system crash or bad ROM, how can I recover it? Furthermore, is it good for normal Java dev?
Thanks in advance.

Dude I don't mean to be rude but if you don't know the answers to these basic questions then maybe development isn't for you. You recover in many ways, by flashing an image file in fastboot or use a custom recovery to restore a nandroid backup if you have one installed. You can store said backups on a pc if your worried about the phones storage being wiped.

*Ahem*
Please excuse the above poster. He meant to welcome you to our community and hope you encounter good fortune during your stay...
Most, if not all, Android phones have a low level recovery utility that is separate from the main storage. In the case of the Nexus 4, you will always be able to reboot by holding down power if the system hangs. In the case of an irreparable system error, you can access the aforementioned recovery utility by holding the Volume down button before and during boot up.
Please, don't let users like this deter you from development. Please use the stickied threads in N4 Development and General to familiarize yourself with Android's idiosyncrasies and xda etiquette.
To Kzoodroid: the guy is new to Android. If he's doing low level work such as kernels, he's clearly more knowledgeable about the development than you are. Knowing how to recover isn't indicative of programming expertise (you definitely don't need the former to have the latter). Recovery is unique to each platform. He's not a UX guy. He's not a skinner or themer. He is the nuts-and-bolts guy.
Thank you guys - both
I'm ok with kzoodroid's message as this is not the worst one I have ever seen - just reminded me what happened to me 13+ years ago in a newsgroup.
It's good to know that I have more choices to recover my device since in the past months I just used SD card to do that on my old ZTE-V9 and thought that's the only way.
Btw: Is there an article or web resource to explain more Android kernel/system level stuff? As many information available are just for user space development with few system diagrams which are not quite useful to me. For example, (data?) partitions, blocks, governor, scheduler and etc. I can get some of them by googling - threads from this forum as well, but still want to get some comprehensive understanding. Or I can look at Embedded Linux to get detailed ideas? Sorry to ask this here since I cannot post anything in the general dev section yet.
Thanks.

Was reading thru some threads when I came across some newcomers crying out for help stuck in bootloops while flashing custom roms.
Since I was free.Thought maybe write my own experiences down and what I did to get out of trouble.
Hope this not so short essay help someone new to XDA.
Let me begin with ClockWorkMod recovery.
I for one,have installed two types of Recovery to be on the safe side.
Anyways having the two does not in anyway hinder either.
Therefore it is only and added advantage.
If that wasn't enough there are kernels which come with preinstalled CWM of their own.
At the moment I've got 3.
I switch roms very often.Many a times in the beggining I often made mistakes and always had to redo the whole procedure all over again.
That means from scratch.Flashing custom roms,rooting and then delve in CWM -
X-Parts by pvyPARTS
which I had to keep downloading again and again from market.
Real pain in the ass!
Now where did I stop in the procedure,yes,after CWM installation,fastboot flash the kernel and now use the CWM to flash the roms and the other zips.
Then came across another recovery tool.
RecoverX by LEDelete.
Awesome tool.Does the same more or less as X-Parts except you need to run this on your PC and bind it to your device.
Color is bright neon blue.Very nice visually.
So now what are my choices.Do I retain one and let go of the other.
Made some enquiries about having 2 recoveries.Feedback,no problems. Sweeeeet. I'll take both!
Then came the kernels with their own recoveries i. e -
mechmetal for FusioN kernels
Did the dancing act at the beginning and very stable versions now.
Thank you.
I'll have that too.The more the better since it was not corrupting my device in any ways.
Presently,very few mistakes in flashing roms. So less frequent flashing stock roms. Mind you,it does require me,at times,to do complete clean installs once in awhile.
For that I have learnt a few tricks.
Flashing stock roms-the usual flashtool.
Since I have the bootloader unlocked,rooting takes less than 2 seconds. Simply a marvellous tool.Thanks to:
AutoRoot by bazoocase
Can't escape downloading from Google play store though OR is there a way?
There is!
Am learning that now but I'm actually trying to get only my most needed apps such as Titanium backup,Astro File Manager, and one or two more apps with its contents and data.
Jesus H Christ,this is only the beggining.There's a whole lot more to learn.But I'm liking it!
So newcomers,this might help you in your stay here at XDA.If via this lengthly passage I am able to help A newcomer I am satisfied.
Note:This are pointers for newcomers who have problems during flashing custom roms and start CRYing when stuck in bootloops.
PS: All the above are true facts.
I learnt by making mistakes here and there.
I did a lot of reading,searching,sending out PM's not getting replies and reading,searching and putting forward questions all over sometimes in wrong threads too.
For that I had been abused and bombarded collectively.But hey,that made me be extra careful.
These would happen to you but don't give up.Practice makes perfect.Don't shy off from making decisions.
You are already here.People can teach your everything but at the end of the day you are the one who is going to press that execute button.
It will for work for some cos they did exactly what was needed to be done.It might not work for some cos they didn't.

LreadyIt is good to see a senior member-op putting up a thread like this without being a know it all, smartass twat! I'm sure all the noobies will appreciate it! I personally worked it all out with a full month of reading. I have a bad temper and did not feel like getting abused and tyrated for asking perfectly legitimate questions! I say the same to all who are having probs and are new, keep reading,asking questions and don't give up! Six months ago I couldn't even navigate these forums properly, now I test Roms and kernels for devs! My biggest tip is find a kernel with CWM preinstalled and prerooted custom Roms! Remember one thing too, Titanium Backup is your best friend and is worth paying for the pro version! I don't like anything that isn't free but TB is worth the money!
To the OP here I think it would be good to insert a nit more detail on how to do these things and use these apps in your thread for those not in the know, maybe even some links! It's alot of work but I think noobies will be grateful! If you want some help to complete a noob friendly thread for flashing/rooting etc. PM me and I will help you write it up! We will prob get berated by others because of similar threads, but I have found them not noob friendly or incorrect! The only reason I still a junior member is because I have not bothered to make posts as have not had anything useful to say till recently!

Similar to the existing stickys, which are highly under utilized by new members, and as shown on a few occasions, by senior members too. Read Read Read, practice practice practice, is the only way anyone is going to learn, and I know because it's what I had to do for similar reasons to you when I knew absolutely nothing when I first joined, and if you're serious about learning how to tweak and mod Android then you need to be prepared to spend an hour or two sat at your computer, as you're not going to learn everything over night, in a week or even a month, and 3 years later you may still be learning, as I continue to.

Hello everyone
I am new to the forum so I am not sure if I am in the right place. I have rotted my xperia arc and I cannot install the CWM. I have tried through Xparts and through the RecoverX (RecoverX seems not to be able to download the recovery). I have done the same thing in the past without havin any probelems. This is the first time that I cannot install it. Any ideas?
Thanks for helping

Q&A

This a noob friendly thread to help people with some common questions. If the mods don't like this I apologize just trying to contribute.
Q... What is the first step in flashing a rom.
A... Backup of your boot.img or everything so you can safely return if a problem occurs.
Q... How do you flash a ROM?
A... ROM>gapps>kernel>root or alternatively if issues occur ROM>gapps>root>kernel
Q... Is a kernel/root necessary?
A... No on both I know one ROM that requires a kernel most don't reading the first page you will know. Root is only required if the ROM has force encryption and you don't want it or need root.
Q... How to unlock bootloader?
A... I'll link I'm a second post to motos website it has a detailed guide to do it through a few simple command promos.
Q... Where do I find all the features a ROM/kernel has?
A... The front page typically where the download button is at.
Q... How do I report a bug or problem?
A... Depends on the problem downloading a logcat app from the play store and sending the xml (text) is a good start. If more the bug isn't found there the dev is more then likely willing to help direct you to the files he needs.
Q... What tweaks do you use to get great battery life?
A... Honestly the phone has plenty but if you need that extra little juice the safest option would be using ex kernels power saving mode to dial down the core frequencies.
Q... Is the key n/a normal?
A... At first I thought I did something wrong but no need to fear a simple warning saying there is something custom ie twrp.
Q... My phones encrypted help!
A... A backup could save the phone if put on an SD card. You'll need to format and lose all data stored on the phone other then SD card so be warned.
Q... What's the best ROM?
A... Only you can answer this each ROM is unique and has custom featured tailored to different people. Need bare bones los has it need more aokp among many others have it. You get the point honestly just try it and see backups help here too.
Q... Was this phone a good purchase?
A... Thanks to the devs yes it is. Moto has skimped on updates lately but we still have 7.1.X because of them.
Q... Why is this X ROM unstable?
A... The devs are working hard some phones need to have six months to get los to even work so patience none of these roms are really unstable. The htc 10 didn't have BT for months and on los the dialer didn't even work but now fully functioning. So rest assured every darn bug will be squashed in time.
Q... Is the above mention stuff risky?
A... If it voids warranty yes then it is. Android has come a long way and it is however much safer now then every before to flash and root phones if there's a problem there is typically a fix. I do recommend new users to read as much as possible on risks and how tos first this is only a brief guide to the world of customs.
Q... Where do I find an answer to a problem I have?
A... While I'll support as many questions as I can in here I'd like you to do something's first. Search a thread that has some relative info say a twrp issue search the twrp thread. If that doesn't help google it and see then. Spend just five or so minutes and if no luck then come ask away in here.
Q... Why research when I can ask a question?
A... This is mainly because the people helping don't want to repeat too many times. However a response from someone can take time and it may not even be the answer you need so to save you time a little research ahead of asking the question could speed up fixing the problem.
Q... If I flash a kernel will it mess with twrp or firmware?
A... Twrp has its own kernel it runs on so kernel shouldn't mess it up. However it does mess with boot imagines so it could potentially do that rho highly unlikely. Firmware nope nothing you do really messes with that
This is by no means a complete list of things. This is tailored to our device so please keep it on such so I can help with device specific questions. If more needs to be added pm and I'll add it including suggestions and request for frequently asked questions I may have missed. Good luck on your journey cheers.
