I am here today to tell you how to clean a dirty JTAG / RGH HV so it can be used on Xbox Live.


I have made this tutorial to basically show everyone how to clean the new HV whenever a dash update comes out. This tutorial is only useful if 100F0 doesn't ever change and if there is no extra security added in the future.

First you are going to need to get the non live retail HV to see how to do this go to this link:
http://www.se7ensins.com/forums/threads/how-to-obtain-the-latest-kernel-hv.803011/

Then you will need to dump the HV from an RGH (Has to be RGH so the hashes are clean)
Use XeDumpHv that was made by Dwack: http://www.se7ensins.com/forums/threads/xedumphv.768399/


Then you will need to use this tool to reverse the XeBuild patches done to the dirty HV.
http://www.se7ensins.com/forums/threads/release-xebuildptch-reverse-patches-done-to-the-hv.1061767/

Now you will have to null the payload that XeDumpHV.xex stores at 0x32500 (Just reverse it all to 0's)

Now you will have a HV with no XeBuild patches, no XeDumpHV payload, clean 100C0 - 100F0 and clean 10100 - 10120 hashes.

Now the only dirty hash that remains is the infamous 100F0 but this doesn't really matter as Microsoft haven't changed this hash in 5 + dashes now so all you need to do is copy and paste EC CA A3 19 10 95 55 8B 7B 60 73 BC 75 1B A3 A9 in to 0x100F0 using some form of hex editor and save your HV.

You now have a clean HV that can be used to go on live when used with the correct live files and challenge response.

Please note: This is just a basic tutorial and will only apply to every dash if the 100F0 doesn't change and no further security is added. This tutorial works for dash 17150.

Not necessarily, information was all public just now Chr0m3 spoon fed everyone who lacks common sense lol.
I don't see how this tutorial has anything to do with "common sense." Maybe this sort of thing is easy for you or for others, but everyone starts somewhere. There is no need to be condescending and accuse someone of lacking common sense just because they don't understand something about modding that you do.

chrome strikes again to acquire more fame.
Or maybe it's about time this information is public? I mean it's quite clear MS doesn't give a **** anymore about 360.

You can't use 360 Flash Tool for the new kernels.
I tried using jrunner but you cant even extract a kernal file with that, what program can dump a new kernal?

I agree. I think we should tell how to gen 100F0. That might force their hand to change something

Use Kernel Updater that's linked in the OP to update from the base kernel.

Meeeh

Code:
***************************************************************************************
*** Extracting Kernels....
***************************************************************************************

Extracting Base HV & Kernel
Version 1888
Writing File 'C:\Users\Chrishockey55\Desktop\GoGOGOGO\Kernels\xboxkrnl.1888.exe'

Extracting Patch 0 HV & Kernel
Version 17148
Writing File 'C:\Users\Chrishockey55\Desktop\GoGOGOGO\Kernels\xboxkrnl.17148.exe'

*** Done

clean 100C0 - 100F0 and clean 10100 - 10120 hashes.
Are you inserting 0's in these spots like the 0x32500? And is that all the way through 100F0 or just up to it, you did not really explain that well.

0x32500 is the only block you should be nulling out.
