ISAK.M Posted December 30, 2022 Report Share Posted December 30, 2022 I have a 1.4 with wrong BIOS flashed to the TSOP so I got a china clone Aladdin XT Plus 2 and so far it just has not worked. Turns out its bcs pin 5 only gives 0.17V. Can I solve this or am I screwed? Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted December 31, 2022 Report Share Posted December 31, 2022 Are you sure you are measuring the correct pin of the LPC Debug port? 5Vdc is on pin 6, not pin 5. LPC Debug Port - xboxdevwiki Pin 1 has the square pad. LPC Debug Port - Pin Layout Name Pin Pin Name SERIRQ (v1.0) 16 15 3.3V SDA 14 13 SCL GND 12 11 LAD0 LAD1 10 9 3.3V LAD2 8 7 LAD3 5V 6 5 LRESET# PWR (v1.6) 4 3 LFRAME# GND 2 1 LCLK Quote Link to comment Share on other sites More sharing options...

KaosEngineer Posted December 31, 2022 Report Share Posted December 31, 2022 Ok, what does your Xbox do when powering it on? Edit: Disconnect the ground pad connection end of the D0 wire. Does the console boot without it connected? Quote Link to comment Share on other sites More sharing options...

The solder is balled up on top of the pin header pins not making a good connection to the LPC Debug port signals. Edit: The solder and pad were both not hot enough for the solder to flow into the plated through hole and around the pin header pin to make a good connection. Reheat / reflow them. No more solder is needed. Quote Link to comment Share on other sites More sharing options...

The console does not boot without it connected as I flashed the wrong BIOS. I flashed a BIOS for a 1.1 while I have a 1.4. It does not boot with it connected either bcs of this 0.17V on pin 5 Quote Link to comment Share on other sites More sharing options...
ISAK.M Posted December 31, 2022 Author Report Share Posted December 31, 2022 I should add that even the via that is connected to pin 5 also shows 0.17V Like there is a bigger issue other then my soldering here Quote Link to comment Share on other sites More sharing options...

The BIOSes you should use are MULTI_VERSION that run on v1.0-1.4 consoles and some of them have a separate v1.6 specific release too (e.g.,EvolutionX's M8plus_16.bin and Team Xecuter's, x2_5035_v16plus_512k.bin).

Does pin 5 stay at 0.17V? Quote Link to comment Share on other sites More sharing options...

ISAK.M Posted January 2, 2023 Author Report Share Posted January 2, 2023 Well yeah its 0.17V no matter what, except not always. I measured what it is during those 2 first boots before it reboots a 3rd time and then just sits there. 1st boot: 2.2V 2nd boot: 3.3V 3rd boot: 0.17V So something just makes it instantly dip down to 0.17 but idk what it is Quote Link to comment Share on other sites More sharing options...

ISAK.M Posted January 2, 2023 Author Report Share Posted January 2, 2023 https://imgur.com/a/3NAcfiH I found a random blob of solder that I dont remember putting there that was shorting 2 points so I managed to sort of melt and scrape it off so thats not shorting anymore. I did also find that R7D10 also shows 0.17V. This part has solder points aswell and I dont remember what I was doing here its so random. Its not connecting tho so something else is forcing R7D10 to be 0.17V Quote Link to comment Share on other sites More sharing options...
ISAK.M Posted January 2, 2023 Author Report Share Posted January 2, 2023 Nvm R7D10 is for write access to the TSOP I forgot that Quote Link to comment Share on other sites More sharing options...
ISAK.M Posted January 2, 2023 Author Report Share Posted January 2, 2023 R7D9 shows 0.17V so I guess I need a new 10K ohm SMD resistor? Quote Link to comment Share on other sites More sharing options...

One side is grounded and the other side shows 0.17V The resistance is 9.85K ohm so basically 10K Quote Link to comment Share on other sites More sharing options...
