XycloMod: flash the on-board BIOS on v1.6
Prehistoricman replied to Prehistoricman's topic in TSOP Flashing
When you run the script or GUI, does the Xbox stop responding to the power button? It should. -
XycloMod: flash the on-board BIOS on v1.6
Prehistoricman replied to Prehistoricman's topic in TSOP Flashing
Try connecting your ground to the other side of the C7C7 cap (the one that DEBUG is wired to). Can you measure the RX and TX voltage after connecting to the Xbox and plugging it in? 3.6V is unexpected. -

You have a connection problem as the GUI says. The script is less stringent in determining if a connection is made. Check ground connection and voltages of the RX and TX. -

Never tried it but you'd need to hook up the some extra pins to power the chip up -
XycloMod: flash the on-board BIOS on v1.6

I think your cmd isn't at the right folder. Easiest way is to open the folder where xyclops_flasher.py is in file explorer, shift + right click empty space (not on a file), click "open PowerShell window here". Then you can run the python command. -
XycloMod: flash the on-board BIOS on v1.6

It means there was a timeout while trying to program. Not a python installation issue but a setup issue. Check all connections especially your ground connection. See if you get the same error every time you try the script. -

No, that image shows a different arrangement. I really don't recommend the AV port option as stated in the tutorial on xbox-scene. I haven't been able to edit my post here. -
256MB RAM upgrade release and tutorial
Prehistoricman replied to Prehistoricman's topic in Hardware Mods
BIOS patcher updated for v1.6 compatibility! I'm not aware of anyone who's tried out this mod on a 1.6 yet but now it's ready for when they do. -
Have you considered using the test points? All the flash chip's pins are broken out to test points on the back side of the motherboard.

The small (0402) caps are 10nF, medium (0603) ones are 100nF, big (1206) are 10uF.

Check the back side of the board directly under bank 2. If there's something like a short circuit there, then it will still cause bank 2 problems.

Xbox 1.6b Hynix RAM blown. Is This A Common Fault?
Prehistoricman replied to BreadFang's topic in Repair
A while back, I read some Xecuter discussion from when the 1.6b started being seen, and people were getting issues including the Xbox no longer working. It feels incorrect to say but it sounds like RAM can be damaged by a BIOS that doesn't trim it correctly on a 1.6. Yes but more specifically the RAMTESTER version. See the readme https://bitbucket.org/prehistoricman/lpcmod_os/src/master/README.md -

256MB RAM upgrade release and tutorial

New Xblast OS 0.64 available: https://bitbucket.org/prehistoricman/lpcmod_os/downloads/ Fixed the 256MB test freezing when less than 256MB is detected (sorry!) -
