How are you powering the chip ?
I had this problem for hours upon hours until some kind folk in irc pointed me too this

"Solder the 3,3V pad to the J2C1. 8 point of the motherboard"

Worked first time for me try it and see.

Yeah and that is with the entire KV.
Also xenon only.
Hex editing a kv lol is never going to get you back on live.

Last i remember there were 2 types of KV one hashed and one not.
Also changing the serial will never get you back on live lol.

Well for what its worth i have had a console on live without dvd drive connected for well over a year and its still going strong

Well there is one way.
Xexloader xmas edition press  LB+X and you get a little jingle which also flashes the rol either green orange and red.
Now if you press the same buttons again it will stop this jingle and the rol will stay on either colour.

You can launch your games or go to dashborad and rol will stay whatever colour till console is switched off  

Have you even used XeXLoader yet?
Has nothing to do with the flash simply burn iso to disc or put live file on hdd

yes

Im not sure how your running your full game ie dvd drive hdd install or usb hdd but from my tests with gta iv my DLC will only work with the game running from dvd.
Have not tested m$ hdd install would assume that works too.

Well im using Xenon 1921 xbr and also get freezes although if i press the guide button and wait a few minutes it seems to unfreeze
Will do for now as i cant complain about the great work put into xbr

Did you just post your nand dump with your key vault    not cool

just tried gta off usb stick and works fine even loads faster 

That is sick been waiting for something like this for a few years now.
If only i could get my hands on some dam resistors right now

OK a while back i thought i saw a post from tmbinc saying there is a method to flash the nand via Xell Linux.
I have tried to look for this post again but I'm beginning to wonder if i just imagined it.

Am i correct in thinking there is a method to flash in Xell Linux ?
If so can anyone point me in the right direction ive searched everywhere for info in regards to this.

well i got a 360 refurb back from repairs about a month ago with a benq and 2.0.2858.0 kernel.
this is in the uk.

well my dash was updated to 5766 too.
pal machine but was previously banned.
