Hi All,
Firstly... I'm no pro... but im not a n00b either, i found the whole firmware update very easy, lets put it that way. Hope that give an idea of what i can and cant do.
I followed the tutorial from start to finish and completed all of the steps...
I managed to backup th firmware and that stored safely on 4 differant devices (you can never be too sure).
When i backed it up i noticed it got to 100% and started again.. it did this about 5 times, is this normal? i gather that just each bank it was backing up?
I then booted into windows and examined the floppy disk and lone-behold a 256k bios fine sitting on there called ORIG.
I then opened this with win hex... and located offset 4000 and copied all of the text between 4000 and 4200.
I then proceeded to open extreme.bin in win hex... located the above offsets and pasted into them. (Maybe ive got this bit wrong or put code in wrong place).
I then flashed the bios from the dos bootable floppy... it went ok... said each bank was ok and overall 100%fine.
At this point i re-assembled the 360 fully, i should of tested it first.... but halfway through putting it back together... i remembered that id forgot to plug sata back into to xbox dvd drive, so i took it all apart again and attached cable, forgot to check if power was securely connected (should of been i never touched it).
I proceeded to re-assamble the whole unit for the second time... at this point it was very late 3am GMT. and i didnt have the xbox connected to the tv... but anyway i turned xbox on and the green ring comes on as tho everything is ok and after about 5 seconds it was giving one red flashing light. bottom right i think.
I was too tired to persue it any further at that time.
Any suggestions people? bare in mind xbox wasnt connected to pc/tv at this time. - but av cable was plugged into the 360.
One thing i should mention is that when i plugged in sata cable to motherboard i yanked a little too hard and xbox fell off my bed and landed dvd drive down... it fell about 1ft. I cursed about 10 times and then picked it up... it wasnt that much of a bang - could this of caused it? i know it has not helped.
I did also remove the black screws which apparently hold the heat sink on? thios was before the unit fell... is it only these screws that hold the heatsink on? as it seemed pretty secure with these out.
Just need some advice or direction - i can follow any instructions pretty well
thanks for your time all.
its much appreciated - and i mean that!
