Images of the G1's motherboard in HQ?

Hey everyone,
I have a strong backing in electronics, and I have a G1. I don't dare open it because it's my only phone and I'm a college student, however, I want to study the circuit board to see how we can exploit the device.
My first idea I want to investigate is just building a chip flasher to flash the ROM. There's no way they could block that. I see the threads on working with the JTAG, however, I'm not familiar in that area. Wouldn't it make more sense to build a solderless chip flasher?
Regardless, does anybody have some high-res images of the board, front and back?

Wrong section, and I don't think many users will hold the high res pictures you are looking for...I could be wrong =)

I wasn't sure whether to put this in Q&A or not, as I wanted to discuss development of the chips once identified.

Does this help any? It has complete disassembly/assemby instructions, and lots of pictures

I looked through it, unfortunately, it did not detail the main board. I really would like to just study the traces on the board. Does anybody have a front and back picture of the main board?

That'll probably help him all the way down to the bottom.

That should help you ;]

Look in the debricking JTAG testpoint thread in development. First post has some good pictures of the top (side that faces the inside part, toward the screen side) part of the board. I had mine open the other day but I didn't take any pics, sorry

[Q] Headphone EMU soldering

Hi i have an origanal headphone/mic for the G1 and it has becoume a bit tatterd over the years, i was wondering if anyone new where the solderpoints on the usb board bit are (well the colours to what solder points.
I have treid searching xda and goodle to no help at all
was hoping someone who had ether the knowledge or the picstures to show me which colour goes to which solderpoint lol..
Thnak you.

Anyone got a busted phone?

I'm looking for a busted captivate for research. I belive we may be able to boot from a micro SD card.
I have to remove the processor and reverse engineer the board in order to find the power supply to the line called XOM5 in the processor manual. Once this line is found, it may be as simple as shorting, slicing the line, or popping a resistor off the board.
Repairing the phone afterwards would be beyond my capabilities.. I can't perform ball soldering. That takes some highly specialized tools. You would be doing a great service to everyone with a GalaxyS phone.
The phone does not need to work, and can be in horrible condition. It can be water damaged or physically broken. The only thing I need is the main board inside the phone.

bump......

Sorry man only got my every day phone. Ill keep an eye out in the island see if i can help with your project.

hey i have a 1008 phone. screen busted. possibly stuck in bootloop. its in a couple peices.

can i just send you the main board?

Yes! that's all I need. I'll send you a PM.

I would like to learn more how a CB works and how to trace certain things on a board as well as other parts. Any books or reference guides besides schematics that could help me? PM me if you will. Infact anyone that knows anything could help me, please PM. Thanks.

A better place for a newbie to start would be circuit bending... hopping electricity from one point on a circuit board to another to alter the operating state. This would be a great place to start... http://hackaday.com/2011/01/11/intro-to-circuit-bending/
Once you get familiar with how things work on a circuit board, start examining the individual components in greater detail. There's some datasheets in here http://forum.xda-developers.com/showthread.php?t=1111866 which you could use to understand how a couple of the major players on our phone works. Speciffically, the USB controller (FSA9480) and the Processor (S5PC110). It really takes some additional education to start reading processor manuals....
You could always start with something simpler like Arduino platform. The Arduino platform allows you to create a basic program which runs on a microprocessor and take inputs and outputs from it. I like the Arduino because it's so darn quick to pick up.
here's some of the stuff I programmed on the Arduino

This one would be a great first project. http://www.hyundaiaftermarket.org/forum/blog/3/entry-26-arduino-ef-meter/
If you really want to understand how a circuit board works, the best way is to go to school, or start playing with one... You could get started pretty cheap http://www.google.com/search?client...gc.r_pw.&fp=d4257c808144b93c&biw=1333&bih=651 or you can get a better one like in the Android Open Acessory Kit (it's actually an Arduino Mega with additional sensors) http://www.google.com/search?client...gc.r_pw.&fp=d4257c808144b93c&biw=1333&bih=651
So yeah... Learning electronics is reading, playing and doing.

Hey, thanks a lot. I'm sure I'll be able to get something out of it. Hopefully this will help with my job some too!

Hey , when and If your able to boot from micro sd...will this method be like the nook color?

Basically. that's the idea. perform a slight hardware modification, then boot from SDCard from then on. Of course, first, I'll be focusing on just recovering a bricked phone by providing the phone a PBL/SBL/SBL2 on a MMC card.

Any progress?

Which units to buy MTCB or MTCD?

Hey guys, I have one friend, want a unit for his car, and now looking all the stuffs, I have a questions, what it is recommendable right now to buy MTCB or MTCD? When we will gift one MTCD unit to Malaysk? xD
The car is Toyota Land Cruiser/Prado 150 ¿Any suggest?
best regards.

Just another post in the wrong forum section...
Please read this forum section description, standard Android head units are not Android Auto devices!
If you don't know what is the Android Auto system, just have a look:

MTCD

I did not know where to post this same question so I would like to piggyback on this one.
looks like there is a lot of development work here for MTCB and that the MTCD is starting. I have a newsmy and I am thinking of switching to a different unit with more support and activity. I am looking at 2 units, both Joying, JY-UQ130 and JY-UL135. one is MTCB and one is MTCD, I know by reading the forums I can update the UQ130 to 5.1.1 So wich would you do and Why?
I see one prior post that says MTCD, but no real reason.. THANKS

[CLOSED] Identify Seicane H6032N android 10.0 headunit?

Hi guys, is anyone able to identify the type of MCU this Seicane Android 10 head unit is (pictures attached) and if its possible to root and install any custom rom? I have only recently made this purchase and I am yet to receive the head unit so unable to give any further info. It was purchased from aliexpress and the info in the specs is a bit vague. Any help in identifying this unit would be appreciated.

Not android auto, Cross post, OP given advice in that post, ignored and doesn't know what the actual hardware is.
