Friday night i got home excited to try a ram upgrade have a perfect V1.1 in a crystal case, what could be better soft modded, unlocked the TSOP, flashed x25035 using hexen, swapped in a big sata drive/80wire ide/ installed XBMC as dash, smooth sailing... So i had purchased a set of chips from utsource about 4 weeks ago and when they got here i only had 3 chips... checked my invoice and realized i had ordered and paid for 3 chips... bummer So in haste i ordered 5 more from an ebay seller in the states... i had ordered K4D623238F-QC50 Got all 5 I installed 4 of them after the TSOP (in the same night) not realizing this is a 512K chip and the XBOX needs the 1M all the way up to the 4th i was getting orange and red flashing.... good sign, diligent with continuity tester on the 4th it was clear something was wrong... i went to bed frustrated with a few unknowns. Got back at it and installed the 3 utsource chips in place of the 512's, when i had all 3 in with 4 still being installed i realized at flashing orange and red the eject button would boot the X2 bios??? what sorcery is this. The ram wasnt being recognized but it prompted me to consider XBLAST (which i was vaguely aware of) seeing as i had access to HDD/FTP from dash https://bitbucket.org/psyko_chewbacca/lpcmod_os/downloads/ Found the xbe version, booted from XBMC and actually had a success on 1/4.. now im feeling ok. Re-flow the other 3 (XBLAST has a diagram entailing which chip is which so you can refrence their test screen) now i've got 3/4 testing positive. very excitedly I open up another xbox i use and harvest a chip (hell i can replace it another time!!!!) Well, the removal goes spotty at best and by the time ive lined up the pins and got the soldering done one of the corner pins breaks off while im trying to make a small adjustment.... angry i take it off the board.... lift a pad.... now you've ruined a wonderful console, and have 3 chips to remove and not enough supplies to outfit anything with an upgrade. remove yourself from the situation, breathe deep and take a nap. luck is funny. http://pdf.datasheetcatalog.com/datasheet/SamsungElectronic/mXxqxqv.pdf After examining the pinout of the chip i realized the center pins of the right and left side are named N.C..... what could that be? is it possible thats pin for the pad that lifted?? Ii find another datasheet that explains the definition of N.C as "reserved for future revisions" otherwise: This pin doesnt get used right now... WHAT!!?!?!?! Sure enough the lifted pad is N.C on the pinout diagram Just yonder a warm optimism drags me back into the basement. Now focused, rested, and caffeinated i go to work at harvesting another IC from the 1.4. a fantastic removal, straight pins and all. Get the chip down with no hiccups and wearily stare at that grey pin on a brown backdrop (lifted pad) all back together XBLAST reports 4 success' victory is sweet XBMC sees it, Virtual Cop 3 boots.... YES!!! Despite so many stupid mistakes it worked! But its not all roses i wasted 30 bucks on 5 ic's i will never use and also the fact my 1.4 is now in limbo. so i can either replace the 2 and call it a day..... or...... order 6 and spend another 12 hours hunched over a 17 year old game console..... i think i'll take the latter.
