[Transformer TF300T Q&A, Help & Troubleshooting] opethfan89:
I'm new to the Android/Rooting community so take everything I say with a grain of salt. I'm still learning, but this is what I've learned in the past month of tinkering with this stuff:

1) A custom ROM is like a custom version of the software you interact with. Android by itself is not configured to each specific device it is installed on. So, the manufacturers (like Acer, Asus, Samsung, etc) take that android compilation and configure it for the devices they sell. Each of these configurations is different and some of them prevent you from having full functionality, whereas others might be bloated/slow/need other tweaks. Enter some awesome guys here on the XDA-forums and other places who took these manufacturer-specific installs and stock installs and customized them to enhance performance, battery life, change the look and feel, and offer various tweaks & fixes.

2. A kernel is the underlying code that runs the operating system. I haven't messed with this stuff yet, I don't know much about it, and if you don't know anything just DON'T mess with it. Breaking the kernel will completely prevent you from using your device (I'm applying my computer knowledge to assume the Linux/android kernel operates on the same principles as computers)

3. CWM recovery stands for clockwork mod recovery. Basically, these stock tablets and devices include a "recovery" module built-in that lets you backup your tablet and hopefully restore it in case things go horribly, horribly wrong. CWM is an after-market/3rd-party recovery that has a TON of functionality and is very well-supported and updated. Most tutorials assume you HAVE CWM recovery installed so its a pretty awesome and pretty important program to have. The CWM recovery wiki has more information depending on your model of device.

I hope this answers your questions, and if I am mistaken in any aspect I encourage another member to correct me.

Thanks,

Opethfan89

as for your other question about bootanimations....you only have to be rooted to install a boot animation. and depending on the original location (some manufacturers put it in system/media orthes in a non-root required location)

find an animation you like, download it, use root explorer or another file explorer and copy it to the system/media folder and change permissions to rw/r/r and reboot and it will play the new animation.

there are also apps on the market (Rom toolbox) that has a TON of tablet specific animations, it will download them, and install them for you....and as long as you are rooted you just have to sit back and relax :)

[Galaxy S III Q&A, Help & Troubleshooting] shadizar1313:
I am an apple convert, go ahead fanboys, flame me all you want. I am a tech geek and I try everything out. I want to learn and I want to play around with the toys that I buy.

I have fiddled with the SDK and the SDE. The company I work for built an Android device for military use, so I know a little about the processes used in hacking and development.

The thing I want to know is WHY is it in just about every thread I read, there is an assumption that everyone automatically KNOWS how to install a rom or kernel or anything else of that nature.

Go to the Aroma installer thread for example. There is a comment from the developer that states "Do not ask how to install Aroma. If you have to ask then you don't know what it's for". Well, bull****. I want to install a custom rom on my phone that utilizes the Aroma installer, but i cannot find any instructions or documentation on how to install Aroma. I can find all sorts of examples on how to use it, but not how to install it.

Now I created a theme way back when for the G1, I previously owned the Thunderbolt and have installed roms on it. But each device is different. Why is it so hard to make a post to help out the new guy?

I am sorry for the rant, and if the devs want to delete this post, then please do so. But I am frustrated to hell with the android community spouting how much better they are than anybody else. It;'s like some damn good ole boys club from redneck USA. Why not help spur on the community and share the knowledge?
[Galaxy S III Q&A, Help & Troubleshooting] slaphead20:
because dear sir there are a lot of android forums out there, but this is a mobile phone and tablet development forum,, with rules that you need to read, and a journey of learning you need to take,, this involves reading and searching and accumulating knowledge, a far cry from having Apple sauce wiped from your chin ;)

And yes,the journey is mentioned in the forum rules. Welcome to the world of free people :D

[Galaxy S III Q&A, Help & Troubleshooting] RomsWell:
First u don't install aroma its a installer. U flash a aroma Rom the same as any other. It just guides you thru the install. Depending on the dev it has options to pick thru durning install. Like auto removing built in apps or installing a theme. It's just a installer.
[Galaxy S III Q&A, Help & Troubleshooting] natefuhr:
Can you please point out where the "banging on about iOS" happened?...
[Galaxy S III Q&A, Help & Troubleshooting] shadizar1313:
I completely understand this part. This is what I am trying to find information on. How do I get the Meta-INF folder onto my Galaxy S3 so that I can utilize it's features and functionality to install the ROM.

In the past, i used clockwork mod to install roms onto other devices. This is where I am stuck and where I am trying to locate information.

Thank you for the reply

I am trying to install the Dragon ICS rom, but it uses Aroma which I have no experience with.

I guess trial and error is not the best way to go with these things. I finally figured out how to get Aroma installed via the Clockwork recovery, and then went on to install Dragon ICS, the kernel failed, not the device will not turn on.... oh well...

Back to the drawing board I guess, Thanks anyway...

To me what matters is people who are smart enough to understand a phone OS usually pick Android, I mean just because Westlife outsell the Beatles does that really make them better? No it just means they more popular because of the image in the same way reality show acts are guaranteed a number 1.
[Galaxy S III Q&A, Help & Troubleshooting] speedyjay:
Its not difficult....just follow the on screen instructions....really quite self explanatory!
[Galaxy S III Q&A, Help & Troubleshooting] natefuhr:
As far as I've seen from the OP, there has been no "talking about apple products"... Just this...

Go troll elsewhere please?
[Galaxy S III Q&A, Help & Troubleshooting] speedyjay:
This threads trolling! Pointless, as mentioned a couple of posts up, probably too lazy to search for the 1000000000000 threads that have already been created on the same subject
[Galaxy S III Q&A, Help & Troubleshooting] AndreiLux:
He's asking for documentation on how to make an Aroma installation not how to use it when installing something you idiots. Half of the replies here didn't even bother to properly read before they replied...

And as far a that's concerned it's a issue of the contributors.
[Galaxy S III Q&A, Help & Troubleshooting] Mister_Mxyzptlk:
The last time I checked, XDA was a DEVELOPMENT forum; not an Android forum. There are plenty of iOS dev threads on XDA. Go troll somewhere else!

As for the OP, AROMA should do all the work for you. Just flash the ROM that uses it, and follow the setup.
[Galaxy S III Q&A, Help & Troubleshooting] natefuhr:
Do you have the time or patience to search through "1000000000000" threads?...

On a serious note, I'm beginning to understand the OP rant on this topic..

He has asked for assistance.. you can either contribute to making another well-rounded Android user or just ignore it all together. Chiming in with useless insults is what has now made yet another thread pointless and has now made 1000000000001 threads on this topic that still offer little to no clear assistance.

So again, I will ask, please go troll elsewhere.
[Galaxy S III Q&A, Help & Troubleshooting] Tectas:
You don't have to do anything except flashing the Rom like usual.

The installer is shipped within the rom.zip.

The only difference is that you get an interface after you accepted to flash the rom, which let's you choose which parts/mods you want to apply.

I guess you modified the rom.zip, because you told "you got it installed", reflash the unmodified Rom and just follow the on screen instructions.

Reread, yes he's asking for documentation, but just to achieve the installation of dragonics, because he thinks there is something which needs to be setup first, which isn't the case, sry if I understand something wrong, but that's how it sounds to me.

I have used the search tool, I have used google to find answers.

The best I have found are vague references to manually copying the files to the phone via root file explorer, yet to use this option, you must know exactly where the files must be installed.

I have spent 7 hours trying to find answers today. I have spent about 15 hours this week searching for more information about what is being installed and understanding how it is installed.

I ranted because I am frustrated, not because I did not search, but because I did and could not find any useful information. If that makes me lazy then I am the laziest person on these forums.

Thank you to those that helped me at least by giving me an idea.... Have wonderful weekend
[Galaxy S III Q&A, Help & Troubleshooting] shadizar1313:
I know that it is next to impossible to "BRICK" an android device, but I think I may have found the exception to the rule. During the DragonICS install, the kernel setup failed. After the device rebooted, it shut down and will not power back on.

At least I figured out how to install the Aroma package, that was the start.

Thank you though
[Galaxy S III Q&A, Help & Troubleshooting] kirE_2o1o:
Apple sucks! (okay, i thought, somebody has to flame to make this thread interesting :P)

How i understood his topic, he wants to know, how to integrate Aroma Installer into his Custom Rom Installation

So may check this thread: http://xdaforums.com/showthread.php?t=1461712

(that took me 1 minute for searching :good: )
[Galaxy S III Q&A, Help & Troubleshooting] Tectas:
Shutdown the device and try to get through download mode using volume up + home + power, if it works flash a new kernel with odin (or maybe a full stock rom).

If it fails (can be because download mode uses the same kernel as the rom AFAIK) do the same with volume down + home + power, this brings you to recovery (should work now matter what, because it uses its own kernel) and restore a backup.

(can be that I mixed volume up and volume down, sry if it is the case).

Hope it works, good luck.

Edit : after shutdown remove the battery for a minute before you try the 3 button combos.

Thanks for the suggestions, I did try these out. I ended up taking the phone back to VZW and they gave me a new phone. This thing just would not power back on at all. Turns out (according to the guy on the VZW helpline). The phone was a DOA...

I know what I Was doing wrong now, the ROM just needed to be loaded through the recovery. Aroma was already modded into the ROM. I just have to load it from the SD card.

I did learn how to load a few items on here today, so now I am that much wiser going forward.

Thank you to all who helped, and than you to all who flamed.
[Galaxy S III Q&A, Help & Troubleshooting] Mopral:
VZW as Verizon?

If yes, do you know that you are in the "international S3" section and that all roms from here will probably brick your phone?
[Galaxy S III Q&A, Help & Troubleshooting] CreekDirt:
Yeah what a bummer. Is Dragon available for the Verizon version?

I agree with the OP about vague instructions. How difficult is it to post a detailed set of instructions?
[Galaxy S III Q&A, Help & Troubleshooting] chrisd1a1:
Ok, firstly i think the op is entitled to his view. Also he raises a few valid points about how some threads make the assumption people know how to do things. Android is like every other operating system. It has to be learned. There is a lot of info on the web so people can learn, particuarly in xda.

Search is a good thing. Questioning is also good.

Secondly. Ive closed the thread as it isnt forum specific. Please dont assume i agree or disagree
[Nexus 7 Accessories] peterpressure:
So similar to what was found on the Samsung Galaxy Nexus, does anyone know where the source file exists that explains what the 4 POGO pins on the left side of the Nexus 7 are for? I cannot figure them out with my multimeter or oscilloscope.

Samsung Galaxy POGO thread: http://xdaforums.com/showthread.php?t=1614287

File on Samsung Galaxy Nexus was board-tuna-pogo.c but that is obviously not on the Nexus 7 because it is made by Asus and I assume they had a different file.

Close up of the POGO insternals from ifixit.com:
[Nexus 7 Accessories] kpjimmy:
My assumption is that there will be a dock of some sort that will be using those contacts.

I make this assumption from my old Nexus One where they also had contacts similar for charging. :confused:
[Nexus 7 Accessories] OriginalFire:
I'm not entirely sure, but one of the pins could be for charging and another for ground. And possibly the other two are for audio out.

Just a guess lol
[Nexus 7 Accessories] tomascivinod:
Since there are 4 pins, I get the feeling it could be USB? 2 for data + 2 for power and since now Android has support for USB audio it wouldn't matter? I just wonder how you could do power and stereo audio since you would need a ground + 2 for audio and 2 for power...
[Nexus 7 Accessories] khaytsus:
Nope, ground is ground. Could use the negative terminal for ground, so could be + l r -
[Nexus 7 Accessories] rmm200:
One thing for sure, unlike the title of this topic, they are not GPIO pins.

My vote is for stereo audio, ground, and charging. Buy a dock from Asus and see.
[Nexus 7 Accessories] peterpressure:
If Asus had one available I would buy it!

That said, here is what I found so far...

Top Pin (1): Ground

2: ???

3: ???

4: Data (minus) ???

Tried hot glueing wires into the pogo ports to conduct more tests, but quickly realized it was easier to just pop the back off and wire them directly to the board itself.
[Nexus 7 Accessories] pokey9000:
Protip: apply 5V between your pin 1 and 4 and watch dmesg.

[Nexus 7 Accessories] peterpressure:
Well, I am hellbent on beating Asus to the punch!

Thank you for this tip! Great help.

I apply GND to pin 1 (top pin) and 5V to pin 4, dmesg (cat /proc/kmsg in Terminal Emulator) says the following upon +5volt insertion.

<4>[ 232.369780] INOK=L

When I remove +5volts it outputs the following:

[Nexus 7 Accessories] peterpressure:
Please do not clutter this thread with anything other than real findings related to the software or hardware involved with the POGO pins.

Ok, small update!

Turn the tablet off, and apply GND to Pin 1 (top pin) and +5Volts to Pin 4 (Bottom pin) and Voila!

IT IS CHARGING via the POGO pins! (but only when turned off)

When I turn the tablet on, it stops charging.

tinkering rox!

Anticipation! I hope you find out the details and are able to make something nice out of it.

My suggestion would be to make something small/slender, that could be adapted to any standard folio type case for the N7 which would allow it to "dock" without taking it out of the casing and use what ever features are available via the POGO.

GL!

Is it possible to see if the pins is routed anywhere on PCB?

What kind of hardware (text on chip etc) can be found close to pins?

Is there any direct connection to usb from the pins?

If possible, ohm measure would be interesting.
[Nexus 7 Accessories] pokey9000:
The two middle pins don't have any of the voltages you'd need for USB host handshake. In fact they're high impedance at DC. I'm pretty sure they're AC coupled audio out.

---------- Post added at 12:56 PM ---------- Previous post was at 12:51 PM ----------

So the dock charging is implemented in the bootloader but not in the kernel. Expect an OS update around the time the dock is released.

BTW Bluetooth V2.0+EDR Audio Communications Module... Sounds fun
[Nexus 7 Accessories] ryhamster:
i got the same thing on the pogo pins only if its turned off but doesnt charge for long
[Nexus 7 Accessories] peterpressure:
Exactly!

So this tablet is very easy to open. I kept looking inside but it is a multilayer PCB, so without further disassembly it would be hard to see.

I think we can figure it out via other means.

How can I test this with a sound device?

I hope this is not the case! Seems ridiculous to require the user update the OS to use the dock, but who knows.

I charged all the way from 0% to 100% via the pogo pins today (with the tablet off). Worked like a charm for me!
[Nexus 7 Accessories] LouZiffer:
The simplest test, assuming there is no detection going on to enable those pins (they're always enabled): Take any amplifier with a set of speakers, turn its volume all the way down, and turn it off. Run a wire from one of those supposed audio pins to a right or left input on the amp. Run another wire from the output/ground on that terminal to ground. Turn the amp on. Play sound on the tablet and gradually turn the volume up.

If the sound is reproduced by the amp, they're enabled and functional. If not, the tablet may need to be fully docked and receiving power before it enables the audio pins.
[Nexus 7 Accessories] elegos:
Thanks from me too, that image is as perfect as clear :) I was scared to fry somehow the battery ^_^

Now... may you tell us please the diameter of your POGO pins? I think the top is 0.9 mm, what about the maximum diameter of the pin?

Thanks.
[Nexus 7 Accessories] Flowyk:
the pins are 3mm from center to center ... you should use pins that have lower than 3mm dia also watch top of pins that must be lower than 2mm (to pass into tablet)
[Nexus 7 Accessories] fierrogt:
Aftermarket option

I'll keep this short in this reply, but I'm considering production of an aftermarket dock that uses the POGO pins. It would sell for $30, but I would need to use Kickstarter it to afford the capital. If your interested there are more details here: http://xdaforums.com/showthread.php?t=2016526

Here's the concept:

[Nexus 7 Accessories] elegos:
Rather than jack audio, why don't you implement two mini speakers?

---------- Post added at 05:02 PM ---------- Previous post was at 04:58 PM ----------

Aren't the tablet POGO pin heads 0.9mm diameter? BTW I can't find any reseller of these pins in europe but digi-keys which seems to sell larger pins.

So will charging the nexus 7 using the pins and connecting a game controller via the microusb on the device work with the official dock?
[Nexus 7 Accessories] Flowyk:
Someone stated that usb host dont work when in dock or dock dont charge
[Nexus 7 Accessories] SINTORMAN:
After reading through the whole thread I have two questions.

1. Will it be possible to charge via the pogo pins and use the otg in the future (ie software restriction) or never ( ie hardware restriction)?

2. What is the difference between the headphone jack and the audio out from the pogo pins besides no volume control? Any difference in quality?

Thanks
[Nexus 7 Accessories] elegos:
1. Being cabled the power pins to the USB one, I doubt you'll ever be able to use USB host when charging.

2. Why should it ever be worse or better?
[Nexus 7 Accessories] Flowyk:
1) its mostly on hardware but of course if there is support then we need software too ... Maybe find a developer that will make kernel for this

2) (experience from sgs2) the signal from CPU goes to sound card and there is modified and amplified for jack but if u use USB port for sound then the signal don't goes through sound card so u get raw signal from CPU that needs to be amplified for use
[Nexus 7 Accessories] MetalMan2:
1) I would think yes - but you could probably do it right now. I can't verify this (since I'm still on 4.1.2... waiting for Team EOS :) ) but any kernel which enables OTG + charging should work. Currently I know of 2 such kernels:

faux123 kernel, but is not specifically supporting 4.2.x yet

and Timur's kernel:

http://rootzwiki.com/topic/30615-can-you-charge-usb-host-mode-simultaneously/ I would suggest going through this whole thread if you have time. He has a functioning kernel for 4.2.x, but I'm still using his kernel for 4.2.1.

2) This also interests me greatly... if the sound quality here is good enough I'll ditch my USB DAC and have a much simpler car audio setup.
[Nexus 7 Accessories] 808HD2:
1) haven't tried it since I don't have an otg cable yet.

2) I have tried the pogo pins with speaker and it would need an amped speaker to actually hear anything. You can hook a speaker up to the pins but its just to silent. With the amped speaker it is pretty good quality, also you would need a volume controller attached since it is on full blast through the pins.
