Greetings everyone! What a first post, huh? Got a tough nut on my hands that I need some help cracking. Hopefully someone of you have experienced this at some point. Slim Trinity tested with Slim proto v2, CR3 lite and Matrix Glitcher v2 revc. I had a look at the 'Common JTAG/RGH Errors and Causes/Fixes' , but my issue only takes place when the outer plastic shell is attached. There's no issues when everything is mounted up and secured in the metal cage. Temperatures are fine, 55C without the fan putting much effort into keeping it there. With stock nand reflashed I could not get the issue to appear, this is with the chip totally removed. The freeze happens on boot or a brief moment after. As mentioned above the console works great when mounted in the metal cage and the issue is only present when outer case shell is attached. Which I think is weird as that should not add any noticable pressure to the cpu/cpu. The bolts aren't too tight either. It all points to an gpu issue, but why would it only be present when the last parts are attached? Nand has been reflashed, soldering checked several times and wires exhanged several times as well to rule out any mistake there. I'm using Kynar 30awg wire for everything but ground and vcc. I've also tried shielded cable on cpu reset and with/without post QSB. No difference. The console itself was rather new and rarely used without said problems. I recall getting a checkerboard freeze pretty early after tagging it, but didn't encounter it for a long time after that. I'm also confident that the IHS has not been lifted as the heatsink has been carefully removed. Thermal paste under IHS shouldn't be an issue already I believe. It's also worth mentioning that I've only had this issue with this console out of several tag/glitch hacks on other consoles. I'm lost, could it be an gpu issue already and would that really be present only when the outer chassis is in place? If you need more information let me know what. Thanks in advance and sorry for any grammatical errors!
