tomahawk Posted February 10, 2023 Report Share Posted February 10, 2023 (edited) Just looked out one of my old original xboxes, It has an Aladdin EX chip like one in picture..The xbox is a 1.6 and only has a 40gb drive and was going to upgrade it to a 250gb drive that I have... So I tried to flash with EvoxM8+ v1.6 BIOS which I ran through evtool to enable LBA48 support. But when I tried to flash it to Aladdin EX it just sticks on erasing as seen in picture. I have tried holding power for 1 second write to chip not enabled,tried 2 seconds same result, tried more than 5 seconds same result...So I take it that chip bios is not writeable. Do I need to flash it with an external device / EEPROM programmer. Or if I take out the SST 49LF002B chip from Aladdin and replace it with SST 49LF020A will I then be able to flash it...

SS_Dave Posted February 11, 2023 Report Share Posted February 11, 2023 Try using Xblast to re-flash it. Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing. Quote Link to comment Share on other sites More sharing options...
tomahawk Posted February 11, 2023 Author Report Share Posted February 11, 2023 Hi SS_Dave, I Tried xblast and when I try to flash xbox just reboots and chip is not flashed...Tried 1 second push of power button,2 second push of power button and more than 5 second push of power button but still can not get chip into flash enabled mode. So I do not think chip is flashable thats why I ask this "Do I need to flash it with an external device / EEPROM programmer. Or if I take out the SST 49LF002B chip from Aladdin and replace it with SST 49LF020A will I then be able to flash it.." cheers Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted February 11, 2023 Report Share Posted February 11, 2023 Try from the power off (Standby) state press and hold the power button for 10 to 15 seconds to power on. Yes you could flash that chip in and external eeprom read/writer or after the Xbox has booted replace the eeprom chip with a 49lf020 then start the flash process. If it was me I would re-flash the onboard bios chip and remove the modchip. Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

tomahawk Posted February 11, 2023 Author Report Share Posted February 11, 2023 I read that the v1.6/1.6b BIOS is a mask-programmed ROM (read-only memory) will give this a try "Try from the power off (Standby) state press and hold the power button for 10 to 15 seconds to power on."

tomahawk Posted February 12, 2023 Author Report Share Posted February 12, 2023 Don't have an external flash programmer to try and flash so probably Just install a 120gb drive in the xbox which the bios on chip should handle and load more games on to it.
