I bought a phone (dual sim, double cam, selled ad iphone/galaxy clone) in Bangkok to replace mine. The terminal is marked samsung (model 9230) but it certainly is not (the brand Samsung is nothing but a label on the battery door, already removed).
The seller offered me to replace the proprietary operating system (linux based) with Android but I did not have time to come back to take it the next day. Clearly understand that a statement like this, collected on a stand, is not very believable, but it could be.
So I would try as a hobby, porting Android. I do not care about the telephone.
I like it only for the dual sim and resistive display.
Among other things, in the return trip I lost the usb cable connection.
The interface is mini-USB 20-pin, non-standard pin, used to power (via USB), headphones, and, being always to the seller, for jtag connector.
So my first problem is to find a way to trace the pin. I searched without results for a suitable cable which includes the connection to all 20 pin (I can easily solder a USB connector standard but not on the mini-usb or modify anoter calble pinout).
Second problem is identify the phone, searching the database IMEI number the phone is reported as model K701 "golden age" brand, the board label report a Z618_03_120426_1155 H3_TY8 id.
I do it this way: download via jtag the image of the operating system, to analyze it and determine if it can be ported to android.
Obviously I need to buy a jtag interface (preferably software linux) and would like to make a good investment (so that also allow me to work and unbrick on my samsung corby or other phones or other brand).

I found conflicting information and confusing, prices ranging between 50 and 1000 euro, and I stopped before making unnecessary purchases.
As this is my first post I think it's better to clarify that I am not a rookie of unix / linux (I use linux since its beginnings) but I'm definitely a noob to Android and I not have a great experience with the phones, up today I have limited myself to use them.
I have a samsung i5500 corby but all my work to date has been rooting to remove some "applications"/crap and install others like smb server.
I would like to dedicate myself to full customization but to date I have found no reason to engage in development.
As I searched the forum and have not found satisfactory threads on the topic I opened a new one.
I want discuss (and learn) about cost and resources for hacking; identify the phone and if is reasonable my intent about porting.
Tank you in advice for any useful link or suggestion.

Gents I just wan to collect some ideas or experiences on my issue. since few weeks my keyboard giving me troubles. Some of the keys are less responsive and need more pressure to type correctly. I am not sure whether it is the rubber membrane or the keypad. Anyone has such experience and any idea what can be done to fix it? Obviously I don't wan to spend 250-300 USD to buy complete set of Keyboard for my old Universal
Not That I Know What Causes It But I Too Would Like To.
Since Having My Brand New G4 Replaced With A Nearly New G4 Device, (Due To A Broken USB Port)
I Too Experience This But Only With The Number 6 Key. (Haven't Noticed Any Others Yet)
If Anyone Knows Why And If Its Fixable Please Let It Be Public Knowledge.

Hi, my USB connector pulled out, so I have been searching for parts & accessories sources. This is just one of many I have found: NEW OEM FULL HOUSING CASE + KEYBOARD FOR I-MATE JASJAR $56.00 total http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=160242894972&ssPageName=STRK:MEWA:IT&ih=006
I am a beginner JasJar owner/user, so most of that I read on this web site is greek to me, but interesting copy. Maybe I will learn something, or not? I love my JasJar and I am sure I am using a minimal of its capabilities. I have a 1gb card in use and an 8gb card it does not see, an Spanish Dictionary card it does not see or I cannot access. I am sure it needs to be upgrades from WM5 to WM6, but I am not proficient enought to do myself. After copying the correspondence there appears to be many versions of WM6 with varying drawbacks. I will continue to read ya'alls correspondence and input when I feel I can assist. Hugh
Hi,
I just saw this :http://www.youtube.com/watch?v=bHJ_Eth1zpk&feature=related
and was wondering how can i do it ? do i need a spacial cable ?
That's a dev unit that is used for conventions. It has a HDMI mini port to allow them to show the device off. They were never made commercially available.
There is some discussion here to see if it would be possible to solder a port on to our boards but that would require completely taking apart your device and physically altering it so I think it will be out of reach, skill wise, of most unfortunately.
So i can smell a lawsuit comming that they are misleading the costumers by showing one thing and selling somthing else!
I doubt you would get very far
Welcome to try though. I will back you up if you like*
*back up will be in the form of moral support...
Can't recall but I'm pretty sure someone here posted a link of a car stereo head unit replacement kit that will mirror the Androids UI when connected. I searched but couldn't find it.
As much as I like the bluetooth option, I dislike the fact that I can't control my phone via my car stereo.
If someone can point out that post or knows what I'm talking about could you please provide the link.
Just to make some things clear: The unit I speak of is not a stand alone unit with its own built in android os, it actually mirrors the ui of the android phone connected to it. I believe the kit comes with 5" & 7" displays.

I did see that one earlier unfortunately, the company is still working on an Android version. The one I did see was around $200+, this one is over $500.
Found it: http://www.customgadz.com/store/product.php?id_product=16
It's only in pre-order status as of now but if you do in fact pre-order then they'll throw in free of charge a choice of the following:
1) 6.5" or 7" or 8" touch screen
2) OEM switcher add-on type A or type B (*not to sure what those are or what they do*)
The price is listed as AU $169.95 which is USD $178.61
@ryandoubleu: Your post was correct this is in fact the Mimics system.
Android car device
There is an Android 2.2 800Mhz 256MB 8GB 6,2" TFT CAR DVD on sale (800 USD to door in Russia) that I have bought recently and after some software installations it does deliver what I have wanted to have in the car.
Nevertheless there are a few major complaints to its performance: http://www.youtube.com/watch?v=cx53a6N7_ws
As well there are several other minor things that would be great to change if possible.
If there is someone interested and able to cook a custom ROM for this device - I can send this device for free as a gift and for experiments. We really want a good ROM for this CA-Fi Car Stereo and the guy's in China don't seem caring enough.
I will check this thread once in a while and provide contact details for anyone interested in developing this device. It is very close to being a great thing for a CAR!
I have updated my email in the XDA profile so you can as well use this option to contact me.
PS
I Have a ROM update file (192MB) that came from the device vendor (dealer). I can send it out for revision.
The way to install this rom on the car stereo is to extract files to the root of a microSD card, insert it, switch off the device, then, while holding the screen tapped, power on – the device starts an install mode. When finished it asks for screen calibration and restarts with a new rom as after a hard reset (erases everything).
Hi
I have a project I am working on which I would need a way of making my phone (SGS3) send a sort of signal to an NFC receiver by just touching the receiver, this will trigger a number of processes on the PIC. My question is whether an NFC receiver is ready to buy and whether there are any datasheets. Also I would like for the phone to only need to touch, no other operation needed.
If you could point me in the right direction I would really appreciate it. Also since I am doing this for school there really is no budget but if the price is too high I may use something else. So yeah if you know any GOOD manufacturers of NFC receivers that would be great.
Thanks
Well, you might need a complete reader chip that can handle peer-to-peer mode. Might be hard to get one. I guess what your doing is building a microcontroller (PIC?). And youd have to build the chip into your controller and write some sort of driver for it. If that should be a small school project, I'd say rather do something else (if school = university and you actually have a lot of time, may try it). Though I haven't seen a company that sells them in low numbers.
Maybe its more suitable to add a complete nfc capable reader to it? Check libnfc for some example readers that are not to expensive.

Yeah so i want to have nfc receiver as a peripheral device for a dev board. Its high school. Also my teacher told me to use bluetooth but i feel it will be difficult to write a program to interface with it. So basically this device will feel the presence of my phone by nfc and send signal to pic. So it only needs it be like a switch action. You see the phone does not need to send any data. So simply this device has nfc receiver coil on it and when phone comes it will be either 0=no phone and 1=phone present which will trigger the pic to carry out other proccesses. Can you tell me what component i would need?
Adafruit.com has everything you need for that project. I have my s3 working with a ras pi and nfc breakout board. They even write a lot of there own drivers, but they have examples of libnfc code working with there controllers.

The microphone on my Nexus 7 LTE 2013 edition doesn't work at all, so I've been attempting to find the replacement part.
Working with ASUS support to get this information has been a frustrating challenge. It seems their support reps are fond of telling you what they can't do instead of actually helping customers.
Does anyone know how to get information on replacement parts for the Nexus 7 2013 edition?
I found this site:
http://www.asusparts.eu/en/partfinder/Asus/Pad/Nexus/ME571KL (Nexus 7)
But the description of many of the parts isn't too helpful. The support reps for that site (Zand Parts) didn't know which part I would need to replace to fix the microphone.
Go to some local store that has an in house repair dept and sells the n7 and start asking a repair tech how they get parts and if they will order parts for you. Some examples would be micro center/best buy/etc.

Thanks. I've been talking to the manager of a local shop, and he said he'd need to take the device apart to see which part is the correct replacement. I just followed up with him via email to see if he'd tell me who his parts suppliers are.
I also talked to ASUS technical support again, and he didn't seem to know whether the microphone is separately replaceable. He said the microphone is attached to the main board, and that my not be possible to detach it and replace it with a separate part.
Either way, I think it would be helpful if people in this Nexus 7 2013 forum could establish a base of tips and knowledge on how to get parts and repairs and deal with Asus. I'll share what I find out, which, so far, has been very little.
A quick update on my quest to get information on replacing the microphone.
I've talked to two Asus technical support reps and gotten different answers.
The first rep told me the microphone is attached to the main board and cannot be replaced separately. He claimed I had to replace the entire main board, which would cost over $200.
The second rep, Emma Zhang, estimated the cost of the microphone to be $10, implying that it's possible to replace it independently of the main board. She refused to divulge the part number or any other specifics about the part. When I informed her that another rep said the microphone wasn't independently replaceable, she said I would have to send in my device.
I've replied to Emma, letting her know that I find her claim perplexing and unacceptable that Asus can't definitely tell me whether the part is replaceable independently of the main board.
Meanwhile, my latest emails to the local mobile repair shop have gone unanswered.
There is a nexus 7 dissambling video on youtube, just watch it to see if its replaceable or not, simple. Don't email for such a subject, go and talk to them, they need to get annoyed from you to help you.

Yeah, I've also talked to them over the phone, with the same results.
I've seen a few Nexus 7 disassembly guides, but not one that answered the question about whether the microphone is replaceable independently of the main board, much less what the part number would be.
Okay, after over a month of evasion from Asus, I finally spoke with a representative who was both knowledgeable and straightforward about replacing the microphone on a Nexus 7 2013 edition. Here's the scoop:
There is an audio input component replaceable independently of the motherboard.
In some cases, it is necessary to replace the entire motherboard to fix problems with audio input.
Even in some cases where it's sufficient to replace just the audio input component, the engineers may choose to replace the entire motherboard anyway.
I didn't ask what the part name or description is for the audio input component.

For anyone seeking to merely replace the mic, this (old) thread is a bit misleading.
The procedure is VERY simple (and obvious once the device is opened by removing the back). The tiny mic is an integral part of the power/volume cable assembly which is relatively cheap and readily available, including from the ASUS part source previously mentioned (look under "cable").
Unfortunately, the proper part - the full cable assembly- does not generally become apparent when searching solely for "microphone."
