Me estoy informando un poquito sobre estos devkit y se les puede flashear a diferentes versiones de kernel con un dvd recovery.
pego lo que he encontrado y alucinais porque si alguno lo entiende mejor que yo...
Different XeDK Types:
Demo Kit:
Used at trade shows like E3.
The most basic model that will run unsigned code, and access PartnerNet.
Test Kit:
Usually has a sidecar attached, wires coming out of the top don't guarantee that a sidecar can be attached. Wires coming out of the top usually indicate a Stress Test console.
Some will have the PIX port installed but have a piece of plastic covering the port. Take off this port to 'convert' it to full Dev Kit
Only the DVD Emulation port is installed though
Has larger Hard Drive, usually about 100-160GB.
Reviewer Kit:
Usually has a 60GB Hard Drive
Shipped to reviewers at magazines, and websites.
Dev Kit:
Has Kernel Debugging enabled
Has to have a sidecar attached. If it doesn't assume that it's not a Dev Kit, until proven otherwise, and even then it still won't work as a Dev Kit until a sidecar is attached. Unless its a jasper prototype jasper.
Usually has a bigger hard drive (100-160GB).
Extras:
Sidecar - This is the big chunk on top of some XeDKs that you see on the internet. It will have either one or two USB-B ports on the back, if it has one, then you can use the DVD Emulation feature, and play Debug/Work in Progress games directly from a computer's Hard Drive; if the Test/Dev Kit has two Ports one will be the DVD Emulation, the other will be the PIX (Performance Investigator for Xbox) port, which lets you see what the CPU is outputting. The sidecar also allows easier kernel debugging. Pictures of Sidecar are above.
Power Supply - 213W, 5 vac x 3 amp PSU required to power a sidecar equipped console. 1 amp PSU's (i.e Retail PSU) will power everything else.
Benefits:
Play test/dev builds of unreleased/prereleased games
PartnerNet is free
DVD drive is not locked to console
Can be reflashed at anytime to any version
Play games off hard drive
Hard drive not locked to console, can use any size SATA HDD
Can take screenshots or videos of games
Play homebrew built XEXs
Backup games to your PC
Multi-region
Downfalls:
PartnerNet is nowhere near Lives status
Cannot play retail games (unless patched)
There is no warranty, so if you get the three red lights, you have to fix it yourself
Getting the SDK and/or SDK tools is much harder than getting the XeDK
Cost is significantly higher than a brand new retail 360
Not all games that are patched can be played
Questions:
How much should I pay for...?
The best answer to this question is, "How much would you pay for this ____(truck,car,house,monitor,...)?" If you still don't get it, there is no set price, it's all based on numerous factors (condition,what's included,type,...). The best advice I can give is base it on how much the other person is selling it for.
PartnerNet, tell me more...
Yes it's free, but you will find 1/900th the populace of Live on it and it does not interoperate with Live. You cannot download movies or TV shows. However, Live Arcade, updates, add-ons, and unreleased versions of those are available for free. Another downfall to ParnerNet is that not all the same MarketPlace downloads are available, you can only download recently added items.
Where can I get the SDK?
http://xds.xbox.com/Can you send it to me?
No.
How do I get it?
The best answer to this question and overall best advice before buying a XeDK, is to find it before you buy one. If you cannot get your hands on part of the SDK then your box will essentially be a crippled retail 360.
Initial Setup:
If you bought your XeDK from a different region use these codes to switch it to your respective region.
For NTSC-M, left trigger+right trigger+D-pad right (PAL-I 60 Hz (Europe))
For NTSC-J, left trigger+right trigger+D-pad left
For PAL-50, left trigger+right trigger+D-pad up (Not supported in the current release)
For VGA, left trigger+right trigger+D-pad down
If the box you bought is being shipped with an old flash version (2K and below) and you're hooking up to a monitor. You will have to use a standard TV until you update the flash to a more recent revision.
Now that you can see the screen you will have to do the initial setup. It's very simple, give your box a name and setup your user profile.
If you have a hard drive you want to use go ahead and plug it in. You should now bring up '360 Neighborhood' on your PC, connect to your box and backup anything on the HDD (if it was shipped with one).
BE AWARE, IF YOU FLASH WITH YOUR HDD PLUGGED IN, IT WILL BE WIPED.
When recovering with a disc, unless you want the hard drive wiped, you need to remove it. If you have a dev or test kit with a sidecar, then you need to go to the Xbox 360 Launcher, press X, Select System Settings, then disable the hard drive. It will reboot, and nothing will appear on the Launcher except Xbox 360 Dashboard. You now need to insert the disc, then restart the kit. After completing the recovery, follow the steps above to re-enable the hard drive.
Now that you have everything backed up you have three options to flash.
DVD Recovery
Using a recovery DVD just load it in and run the XEX that shows up on the menu. It will run for a couple seconds then ask you if you want to flash to Retail or
K.
1. If you choose Retail (Y button) your box will not boot to the 'XDK Launcher' menu, but instead the retail dashboard. Do not worry, you are not locked to this, at any point you can put the same or another recovery DVD and flash back to
K.
2. If you choose
K it will most likely be to update the flash version you are running. There really is nothing you have to do, it will bring you back to the initial setup screen you have seen already.
Remote Recovery
This is a program that is run from your PC.
3. You will only be able to flash as
K using this option, as above there really is nothing to it beyond that.
Playing Games:
If you have any XEXs already on the drive or your box came with any discs, those will run without patching. If you have neither, then you will have to patch the XEX of whatever game or program you want to run.
Patching XEX of Games:
First you are going to have to dump all the files of a game disc to your computer. There are numerous tutorials on how to do this, available on Xbox-Scene. If you try and play it in the XeDK without patching you will get this prompt.
Now that you've got the directory dump, bring up your patching program. There are a couple programs (easily obtainable) that will do all the work for you. After that simply select the MAIN XEX of the game and the patcher will fix that as well as all the necessary linked files. Just leave all options as their default, if you use this same program.
Enlarge
You should rename your new 'default.xex' into something more meaningful, such as 'GTA_IV.xex'. This will make selection easier from the Launcher menu, but not necessary. Now you are ready to put these files on DL DVD or copy the folder to your XeDK HDD.
Playing off HDD:
Go ahead and transfer the entire dumped, patched game folder (from the above steps) over to the 'Game Development Volume' of your XeDK. You can use the '360 Neighborhood' as in the picture below or connect your HDD directly to the PC and copy it over to the same directory.
The 'Launcher' menu will update on its own (no need to reset) and show you the available XEX, along with its directory. Simply run that XEX and if the patch was successful the game will boot up just fine.
