  1. Well, ladies and gentlemen, I return with good news. I have since gotten a good sleep and re-evaluated the situation. I was able to determine that at some point in my perilous evening several pins of one of the RAM chips had broken free of its pad. I corrected those issues, and tested again. The Xbox booted into XBlast and I was able to perform the RAM test with slots 1-3 passing as they had before. I then installed the fourth module and all is well! Fully functional again, with Cerbios reflashed to the mod chip. While I was able to solve the issue myself, I think I should leave the post as is for the next person that comes along and has similar issues. Even if you've completed the job before, mistakes can still happen. Sending everyone that reads this well wishes!
  2. Wow, nice find! Also, thanks for all the content you've been putting out lately. The YouTube stuff is great. Please, keep it up!
  3. Please see link to 10 images of board here https://imgur.com/a/nJotOX1 The machine in question is a v1.0 with fresh electrolytic capacitors installed everywhere a few weeks ago aside from the power supply (Foxlink, with resoldered power leads). It also has an Aladdin mod chip which I was running Cerbios 2.2.0 beta on previously. After successfully upgrading the RAM on a v1.4 machine yesterday I decided to do my primary xbox today. RAM in question is the leaded F-QC50 variant. They appear entirely to be authentic Samsung chips. With XBlast OS flashed to the mod chip, I began with the RAM install. First chip, test, success. Second chip, test, fail. Quick rework and second passes. Then I decide to do the last two together and test afterwards. Test shows 1-3 pass, number 4 fails. This is the one below the CPU and next to the connector from the power supply. Rework number 4 with an iron, not hot air, still fails, rework it again, still fails. Go for a third try and now the Xbox will momentarily boot with solid green LEDs (hard disk spins up, fans spin normal speed, LED on mod chip illuminates) then quickly cuts power. Then will turn itself on again about a second later, usually with no LEDs on the eject button, fans spin normally, LED on mod chip lights, then power cuts out. There is no display. I also swapped in a known good power supply from a different v1.0 and no difference was made. This cycle appears to repeat indefinitely. Sometimes the LEDs on the eject button light up green, sometimes they flash green, other times there is no light at all. I have tried with no disc drive and no hard disk, with just one of those, and with both of them. I removed the fourth RAM chip in an attempt to rule out the chip itself, however the same result ensues. I then removed a factory RAM chip (M-QC50) from a known good console and installed that in the fourth slot, no change. I ended up removing that chip so only ones that passed the test in XBlast are installed. I know it is possible for the chip to be bad, yet still pass. I took the utmost care not to “splash solder” around while installing and/or removing the memory. I taped up the surrounding areas of the board and components with kapton tape before performing any work with hot air or an iron. High quality flux was used and cleaned up. I examined the board thoroughly multiple times and I cannot physically see an issue. Using hot air I carefully reflowed the factory RAM as well as the three that I added. My question mainly is where should I be looking for a solution to this issue? This is not the typical 3 reboots then FRAG problem. Is there a power related component I should be looking at? Any help is greatly appreciated.
  4. Will be trying this on my 1.0’s this weekend. Definitely don’t wanna fork over the cash for a mounting bracket for new fan if I don’t have to. Thanks!
  5. This is quite the fantastic and detailed video! Thank you for being as thorough as you were. I know many people will get help from this and contribute to the members of the OG community.
  6. Wow, I didn't know it could be that simple. Hadn't crossed my mind. Thank you kindly!
  7. Noob here with a soft modded (Rocky5) Xbox. I currently have Unleash as my default, and I would like to run XBMCEmustation as an application. Would anyone be kind enough to write out how I could achieve that? I managed to install XBMCEmustation as my default Dash on top of Unleash, but decided to rename Emustation's .xbe to .bak in order to get back to Unleash. How would I go about changing things to make Emustation as a launch as an app when I want to use emulators instead of Xbox games?
  8. Does anyone happen to know of a program that will perform a similar function that is compatible with Mac?
  9. Holy crap! Thanks for sharing this, this is super exciting to me. Some of these cancelled games are very impressive.
