Hello everybody.

I recently got to thinking about the data retention of the flash memory used in the original xbox. I purchased an original xbox not to long ago that was basically a coma console in that it would have a green light, but no audio or video. Turns out the bios was corrupted or something similar and that it would boot with extreme difficulties after pressing the eject button a bunch of times until the drive ejected. Basically these symptoms.

I did manage to flash a custom bios onto the system and that solved the booting issues it was having, but that then leads me to what I have as a discussion today. Looking at the datasheet for the Winbond W49F020 series of flash memory used in my console, I notice that it has a data retention of 20 years. This means that it should hold the data for about 20 years no problem, but it seems like mine started having issues early. By what I can tell, to refresh this data and basically restart the countdown, I need to reflash the bios to the chip rewriting the data. This brings it back to a state where the data is properly stored and is ready to last another 15-20 years. My only concern about the whole thing is that flashing a new bios can go wrong and cause the console not to boot without a mod chip. 

My question to someone more knowledgeable than me in this topic is, are we going to see more and more stock consoles fail to boot due to corrupt bioses in the up and coming years? I know that 1.0 and 1.1 consoles already have some issues with their 1mb flash chips, but will all sorts of version have issues? ie, 1.0 - 1.6? Is this just a limitation of anything using flash memory in a component used to boot up? I know nothing lasts forever, but I do try to make it last as long as I can. 

Thanks for taking the time to read through this and I hope it can spark some good discussion on the topic. Also if anything I have here is incorrect, please let me know as I am still learning about hardware in general, and I try my best to be accurate in my information.

Yes they will fail... and reflashing won't give it another 15-20 years. The chips degrade over time. Modchips are the best solution going forward for the ones that fail.

Thanks for that. It sucks that they degrade so much. I guess replacing the flash chip with a new one (huge risk of messing up) or chipping the consoles are the way to go. Though a modchip would be the way to go unless restoring the console to look stock. Though reflashing the chip will still work for a while wont it?

      So I recently made use of this invaluable resource to download all of the old Halo 2 DLC onto my original Xbox (https://digiex.net/threads/xbox-offline-xbox-live-downloadable-content-dlc-installers.675/). The title update and four map packs were a no-brainer, but I was intrigued to see "official" Bungie multiplayer game-types included in the installer as well, as follows:
      1. Classic CTF Tank
      2. Covie Gulch
      3. Golden Showers
      4. Peacemakers
      5. Swords No Radar
      6. Team GoldShowers
      7. Zombies
      Interested in knowing how a few game-types were elevated to "preserved official DLC", I did some research. It looks like #1-5 were made available on the Official Xbox Magazine April 2005 demo disc (http://xbox.gamespy.com/xbox/official-xbox-magazine-demo-disc-43/), and #7 was from the June 2005 edition (http://xbox.gamespy.com/xbox/official-xbox-magazine-demo-disc-45/). But my question, while quaint, is this: when was #6 ever officially released? All online "Bungie game-type" lists seem to acknowledge it as one of the officially released game-types, but I can't seem to find its origin. Does anyone recall how they got ahold of it back in the old Xbox days? To be clear, I'm talking about the game-type "Team GoldShowers".

      So a day ago I got a 1.6 xbox with x3 (purple) model in it, and decided to flash force480p bios while I am waiting until my 1.4 with xboxhdmi returns from installer. Flashed that bios successfully, but console does not output any video signal. Also, about a year ago I had another 1.6 xbox with x3ce chip, and I do remember that force480p bios worked flawlessly. Anyone knows what the issue could be?
      Things I tried:
      Wiping X3 eeprom (a+b+x+y on bootanim)
      Downloading bios from multiple sources
      Flashing over various methods (http flash; ftp flash; flash from internal hdd)
      Flashing on both 1-4 and 5-8 banks
      Trying with different HD cables (I have component cables and chimeric systems hdmi adapter)
      Trying on 3 different tvs

      So yesterday i decided to flash a new bios to my V1.1 Xbox Modchip Super Aladdin with the SST49LF020 to remove de DVD drive check and used EVtool to edit a EvoX M8+ 256K Bios, but me being stupid i also decided to change the EvoX logo to be sure the Bios was indeed changed, big mistake.
      The flashing completed, the Xbox turned off and now when i press for 1 second to activate the chip i get no signal from the TV, no animation, no sound nothing. I even put Hexen 2018 but nothing, it's dead.
       
      But it boot to the stock dashboard with a quick press. I've been searching for hours, but still have some questions:
      1) If i buy one of those Aladdin XT PLUS2 XT+4032 that come with a SST49LF020A can i just replace that with mine and it will work? I saw that it comes pre-flashed with a EvoX M8 bios?
      2) Do you know were to buy just the SST49LF020 with the Bios?
      I feel very sad about this, because i treasure my consoles and this was my main and first Original Xbox and would like to restore it.
