Cerbios UDMA5 TSOP Failed Flash [HELP]

[JaKSLaP]

Hi;

So I tried to flash my tsop xbox 1.1 using the latest 2.02r UDMA5 version on a 3tb WD black. My XBOX was previously running EvoX after it finished flash the xbox led now flashes red and green.

 

Could someone please assist.

Have you tried that BIOS with a modchip before?

Did you use the EvoX dashboard to flash the TSOP or something else?

Are you using an 80 pin IDE cable and the Startech Adaptor?

So my xbox was previously tsoped with EVOX, I used the hexen 2021 disc with no issues. 

Xbox model: 1.1

Generic Sata adapter with 80 pin cable. 

Tool used to flash: Geetox (OG Xbox launcher disc 1.5.4) 

BIOS: 2.02R UDMA5

The UDMA5 version is basicly fpr StarTech adapters only. 

So you have two options, get a StarTech adapter and hope that was the problem or get a modchip. (Option three: Desolder the TSOP and flash it with a external flasher)

And a little quote of the read me ...

Retail UDMA5 & Debug UDMA5  
Use At Own Risk, A few IDE To Sata Adapters Do Not Support Higher Transfer Speeds, This Is Experimental.

DO NOT FLASH UNLESS YOU  HAVE A WAY TO RECOVER, YOU HAVE BEEN WARNED!!!!

I think there's one other option to fix it.  If he used Gentoox Loader to flash CerBIOS's 256KB dot bin file to his 1MB flash, it did not resize / write 4 copies of it to fill the entire 1MBs of the memory chip.  

llamma.com's Coma console fix should do the trick without having to unsolder the chip from the motherboard.  This FIX grounds address lines A19 and A18 of the TSOP which forces access to only the first 256KBs of the flash.   

Really 2 long wires need to be solder to A19 and A18 that can be grounded to boot the console then disconnected from ground to reflash the 1MB TSOP using either Evoxdash or XBlastOS which both write 4 copies consecutively of the BIOS's 256KB dot bin file to fill it.
