So i tried to upgrade my 1.1 xbox to 128mb.
I installed the first chip successfully and xblastOS flashed to TSOP said "Success". Then i attempted to install second chip on bottom side, but xbox started fragging. I fixed up some shorts i found, but it still fragged. Then i measured according to datasheet, that power to RAM is shorted to ground. The shorted pins most likely were: 66 and 65. However it's possible, that i used the chip pinout wrongly and i measured short between VDD and VDDQ, which should be fine.
Even after fixing the shorts, it still fragged. After (destructively, but fortunately without ripping any trace) removing the both installed chips, it still does very weird frag. Basically the LED lights up only for short while and then turns off. Xbox's fan runs for a while and then it reboots. This gets repeated indefinitely, but rarely you get normal FRAG and xbox stays on. I measured 2.65V going to the VDDQ pin and the RAM power rail or any of the main power rails are NOT shorted now.
ANyone knows if i can fix it? All my other xboxes are either fragging (i have 1.0 i got fragging, but it might be TSOP issue as there are no signs of tracerot, no leaking caps and apparently TSOP might naturally degrade now, so i ordered modchip and will try to install it) or they are 1.6, which suck

Here is reference image how i installed one of the chips, that worked well (the first one). I guess it was pretty good: Please login or register to see this link. . The residue is either flux or denaturated ethanol i used to clean it up.
I'm a new member of the forum and I have been playing around with the OG XBOx for a couple of years now. I never owned an XBOX before so my knowledge of the history is relatively limited. I do enjoy the versatility of the original XBOX, and I am amazed by the huge community and custom stuff that exists out there.
Some of the machines I acquire (~40%) come with the modchip installed, but still have the original HDD. In the past, I removed the modchip because I could not find any info about it, and proceeded with a softmod, disk upgrade and so on.
However, after I discovered this forum, I am having second thoughts and I am thinking maybe it is better to keep the modchip and follwo a differen approach.
So, the question is, if there's an advanctage of the old modchips (probable Alladin II, I think) versus the more recent softmods.
thank you very much in advance!
