BIOS Flash failed

Post by tim619 »

Hey guys,

today I wanted to try if my tsop is writeable (it was already a chipped xbox when i bought) and used AID for this. I selected flash tsop (only possibilities where ms bioses)
but than my chip (i think aladdin) got flashed. after turning on no screen signal appears and the drive cannot open. furthermore the led cycles or stays green or orange randomly.
does anyone know how to easily disable the chip (i hope my 500gb hdd is locked correctly to use "softmod")?

greets

e: when i press 2 seconds the power button the non chip bios will be loaded i see this because when i put video cable off its green orange and else just green
but no video and sound and no drive than.
when just press the power button or eject it goes on, off, on, off and than cycling.. also no video and audio but drive works..

Sounds like you've fried the chip, I've never had an Aladdin so i have no idea if it has a second bank that you can use but if you look up the instal diagrams you will find a connection called D0, cut this and your box should boot again as long as your hdd was locked and the ms dash is were it's meant to be

Unless the write points were bridged the tsop wont flash, you also need to unplug the chip once you boot up so you dont re flash the chip which is what happened to you.
Does your chip have a switch to load another bios bank ?

thanks for your answers.
I don't know which chip is in because i've never opened the box and bought it shipped, the seller meant "something like aladdin".
so i hope its an aladdin because there i can put off easily the sst and someone with working aladdin could reflash the sst for me.
I cannot remove d0 atm because i have no torx do open. so i hope it will works with unplugged chip but if the chip is flash corectly it is the same bios
and should be same with no video etc...
but this i think is not normal because the only things which differ from original xbox are a bigger, locked hdd (maybe not locked with stock key), so xbox should boot and show error screen.
no if its aladdin its only one 256k but replaceable sst.
i know this with tsop, but i thought if it tries to flash the tsop nothing could happen but it flashed the chip^^.

Unfortunate lesson, it does help to do lots of reading first before doing anything risky.

I never bother with chips myself ( only ever fitted 4 of them ) I much prefer to just flash the tsop using a softmod to gain access to flashing tools like
a modded evodash or shallax's linux flash tool, it does involve soldering at least 2 points on the board but these can be done
with something like this: http://www.halfords.com/webapp/wcs/stor ... yId_255229 if you don't have a soldering iron or dont trust yourself with one.
