Xecuter 2.6CE Developing A Problem?


Recommended Posts

I've had a v1.6 Xbox with a pro-fitted Xecuter 2.6CE since 2005 and its been pretty much perfect until recently.

On two or three occasions its refused to boot either via the Power button or the Eject/Close button. I get a green/red flashing LED typically indicating a hardware error. Sometimes it does that once and then shutdown, others times it frags.

However I found that if I shutdown, switch the chip off, boot to Error 5 (unlocked HDD) then switch off and reboot with the chip back on everything is back to normal.

But yesterday I noticed something else weird: the chip has two 512K banks with the originally supplied custom EvoX BIOS on both. The only difference between them is Bank 1 has the EvoX logo and Bank 2 doesn't. I usually have it set to the EvoX logo one but now it has swapped to the non-logo version on boot. It doesn't seem to matter whether I switch banks or not.

You might think a connection problem with the switch array ie. it is stuck on Bank 2 but, here's the weird thing: if I Reboot from my Unleash main dash or IGR the EvoX logo version BIOS appears to be used.

Never heard/read about anything like this - any ideas what is going on?

You could try spraying some contact cleaner or even use isopropyl in the switches and work then back and forward a few times.

Also check the soldering of the LPC rebuild.

Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

I've always thought that the cheap quality switch array might be a source of problems so I've rarely played with it over the years.

I just don't understand how cold booting and rebooting could use different BIOS on the same chip. If the EvoX logo version BIOS was corrupted and it was set up to use the Bank 2 BIOS in such circumstances (is that possible) how come Bank 1 BIOS is apparently being used on reboot etc.

You explained a few months ago here, all new info to me, that the BIOS for the Xecuter 2.6CE is an unusual beast that needs a combined single BIOS file to install two different 512K BIOS. I'm probably showing my ignorance about how these things work but Is it possible that part of the Bank 1 BIOS initial boot commands is corrupted? However the rest is OK and as they are not used on reboot or IGR the Bank 1 BIOS, otherwise working, is still being used.

Just an update: the chip is now back to behaving normally. Boots the bank 1 'logo' Evox BIOS as normal and reboot.

So whatever it is/was is it appears it is not a BIOS corruption issue.

Whilst that is welcome it just adds another level of mystery to the problem.

      This item sold on Ebay on September 5th, 2021, but buyer just messaged me saying he doesn't have the money. Officially by Ebay, I need to wait until September 9th and I can sell wherever.
      I am in Utah, hoping to ship in USA if possible. $300 + $25 shipping. I'm hoping to sell this system first and see how much of a loss I will take and then likely sell my other 3CE system also...
      See photos here:
      Currently loaded with 311 of the best XBOX games, but you should be able to fit EVERY XBOX game ever made for XBOX on this 3TB HDD if you use the HDD READY versions (I can show you how). Everything works correctly, ready to boot and play!

      I am an expert solderer. I’ve done 10,000+ repairing vintage recording consoles, so the soldering on this is expert quality.
      Labor was installing the Xecuter modchip (soldering), removing the clock capacitor and replaced with a capacitor (needed for the revision 1.6) (soldering), replaced 22 capacitors on Motherboard (soldering),removed all the old thermal paste on 2 heat sinks, used fresh Artic Silver thermal paste, clean inside, clean fan, install Ghostcase, install 3TB hard drive, install StarTech adapter, install upgraded 80-way cable, clean inside DVD drive and clean optical, format hard drive, install XBMC4Gamers and the best dashes, load 166 games, test. TruHeXEn 2021 DVD-r included.
      This sale also includes the black cover and old parts including a baggie of the old capacitors.
      Current DVD Drive is a Thomson TGM600 wrorking great. I installed the Ghostcase top so you can see the spinning DVD , but old cover is included.
      Sale includes power cable, HDMI cable, and composite cable. And 2 controllers included.
      All new parts were just bought in August 2021, so this is a fresh build with low hours! I can include documentation and receipts if desired.
      The Blue LED Kit is just tacked in place with hot glue in top center. It can easily be peeled off and moved if desired.
      I currently have 2 different systems for sale, see separate ads 3CE and 2.6CE...

      Hello All,
      I have what seems to be a fully working Xecuter 2.6CE in a Revsion 1.6. XBMC4GAMERS and games are working, but I can't seem to find anywhere in settings where it shows the bios version or that it even recognizes the Xecuter 2.6CE mod chip. If I hold the black or clear button on controller during boot, it just loads normal to XBMC4GAMERS. Same if I hold the power and eject button at same time on startup. I do NOT get a "Xecuter Rox My Box" logo on startup screen, but only "Microsoft". Is the "Rox My Box" only a X3 thing? I get a "Evo X" in top left corner of the same green xbox loading screen. Just curious if my bios could be a better version or if I should just leave it all as is since it is working.
      If I select Bank1 or Bank2 on the switch on front of unit, both load fine and work, but seem identical. Where do I find what bios version I have? Thank you!

      I acquired a few Xbox's cheap recently that were broken one of which was throwing an Error 5 on boot. This Xbox turned out to be modded but the solderless LPC header wasn't installed properly, I removed it and soldered a header directly to the board (and wired D0). Now I'm able to boot to the chip but it halts on startup.


      I Attempted to load Xenium OS 2.1 recovery CD but the menu never comes on the main screen. It did early on but went black and never loaded again. I have tested this drive on my 1.6 Xbox and know that it is functional.

      Also I installed my Aladdin XT modchip and the system will boot fine with that. Is there any way to recover this chip or is it dead?
