[K3]+[DXG] Un-demo information

[mcquackers]

Make sure you set the hyperterminal settings correctly via the directions. Make sure you can connect via a com port and you have the baud rate set correctly. I have no idea if you fried it or note, I only used a 1.8v which I knew would work.

Thank You.
But I tried this link.
It's died - that's a reason of my request here.

wanted to thank you guys for your posts on the forum and any guides you made, got my dx up and running after a day of learning the ins and outs of Ubuntu!

I followed Yifan Lu's debricking guide and with a little help from McQuackers My DX is up and running!

For the record I used this Serial Connector : http://www.mouser.com/ProductDetail/...252bb/GLoFR6IZ

Connected from the headphone jack to the left: 4. Black (grnd) 3. Yellow (RXD) 2. Orange (TXD)

Also I would like to note that If I ever find myself doing this again I will invest in a soldering iron.

seems to work fine for me. Here it is as a live link.

Hi progress has been made.My usb adapter was junk.I ordered a real serial adapter with the max 232 chip,Put on a 3v external power,I am reading the characters in the windows terminal.However I cannot send files.in Uboot I tried to send files It says no response from the remote system.Anybody have an idea or a workaround?Thanks

You stand a good chance of junking your Kindle if you don't run the interface at its designed value of 1.8 volts.

Anybody knows where to order a serial adapter with 1.8 volts?

Get a http://www.mobileread.com/forums/sho...7&postcount=68

1.8v remember... check the voltage.

but seriously - I just read back this thread to get these links??? (its only 6 pages)
maybe do a bit of hunting yourself

seek and ye shall find.

You don't need 1.8v adapter for DXG.
I used this method http://www.mobileread.com/forums/showthread.php?t=49942
For power I used 1.5v,3v,5v. Two AA bateries .Worked best with 3v.The adapter in e bay is 2$ .Hyperterminal in windows xp works best.Theoretically you might not even need the adapter.If you have the password you might login from kindle developer menu,and be able to see the 4 partitions in linux I cannot confirm this because I don't want to brick my kindle again.In the end my serial console was acting out but it might have been because I changed the hyperterminal program .

Warning: If you don't really know what you are doing, don't always expect to succeed. In this case: Be prepared to break your DXG. 3 Volts is above the voltage used and may always break the device. I really, really consider this bad advice.

That said, well, it didn't break for you. Of course it worked best with 3 volts. That's due to the operational specifications for your typical MAX232, which are at 5 volts. For 3 Volts there's the MAX3232. For 1.8V, typically a ttl voltage converter is needed. Everything else is a dirty hack, so be prepared to pay the price (a high one in case of a KDX, if you ask me). Purely singular-evidence based advice like this is a bit out of place here, I think. And please, don't follow the suggestion to use no adapter at all. 9 volts differential signals are not what a typical SoC will tolerate. You have been warned.

Also note that RX and TX are two different matters when you go over voltage. If your adapter is tolerant, it might still receive data from the Kindle when it has long fried the receiver on the Kindle by transmitting with too high voltage.

[bluesk]

hawhill is right.I am telling from my experience.The voltage in Tx Rx was 2.8v when I measured and everybody here talks about 1.8v.As I said you might not need the adapter you need an usb cable and the instructions here.http://www.mobileread.com/forums/sho...0&postcount=25

When you hit 3 do it from the developers menu alt+E=3 give password and continue from usb in Linux.Maybe I am wrong as I typed from the hyperterminal in the serial adapter but I think I understand the process now.I followed this instructions and was success.In the end I ended up spending the same money as buying a used one in Craig list buy the fun it was worth it.

can the DXG demo still able to register with amazon.com? I read the image is blacklisted and it can no longer be registered with amazon.com

After you Un-Demo it, yes.
