Hispano Posted February 17, 2023 Report Share Posted February 17, 2023 Hello everyone! I will tell you about my problem: I have an Xbox 1.0 with TSOP and 128Mb of RAM (I bought it pre-modified), I have tried to install an Aladdin Xblast by soldering the pinheaders to the LPC port and soldering point D0 of the motherboard to D0 of the chip (I have also tried soldering D0 from motherboard to ground on motherboard) and got FRAG. I have followed Barnito's Lpc Diagnostics (V0.1) guide (https://www.ogxbox.com/forums/index.php?/topic/239-lpc-diagnostics-v01/#comment-945) to verify voltages and continuity. With respect to continuity everything is correct except pin 2 and with respect to voltages everything is correct (+-10% of the correct voltage) except pin 1 0V and pin 5 1.7V. If I disconnect the D0 cable from the chip or ground, or if I disconnect the Aladdin chip, the console boots correctly with the Cerbios bios that I flashed in the TSOP and boots my Xbmc4gamers. What could be the problem? (if photos are necessary, I'll take them later when I get home from work) Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted February 17, 2023 Report Share Posted February 17, 2023 It sounds like a soldering issue and pictures of you work will help. You do know you can also run Xblast as an app/program from the HDD or as a live app on the OGXbox installer DVD v1.5.4 from here https://1fichier.com/dir/mX1kipIz Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing. 1 Quote Link to comment Share on other sites More sharing options...

Hello again! Here you have the photos of the solderings that I have done, I have reviewed pin 1 and pin 5 a bit but I have not achieved anything productive. I hope it helps to find a solution Quote Link to comment Share on other sites More sharing options...

Here you can see my Xbox booting fine with TSOP (Aladdin disconected) Here you can see too the voltages booting with and without modchip coneected: PIN BOOTING WITH ALADDIN (FRAG) BOOTING WITHOUT ALADDIN CONNECTED (BOOT TSOP BIOS – CERBIOS) 1 0 1,63 2 0 0 3 3,28 3,25 4 - 5 0,15 0,33 6 5,05 4,98 7 3,25 3,22 8 3,27 3,21 9 3,28 3,26 10 3,25 3,23 11 3,25 3,23 12 0 0 By the way, on pin 5 before applying my soldering iron again to it, it gave +-3.3V... Now it gives very low voltages both with and without the chip Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted February 17, 2023 Report Share Posted February 17, 2023 Some of the soldering doesn't look that good in particular the ones in red that look like a cold solder joint. Apply about 50% less solder and set your iron a bit hotter.

I have soldered again the pins that you have indicated and some more that I thought had a lot of soldering (seeing now the pictures, i think that pin 10 is bad soldered ), I keep getting FRAG with the Aladdin chip connected and booting without the chip connected. I show you images of how the pins have been soldered now (by the way now it gives the correct voltages if I measure them booting without the chip connected): Quote Link to comment Share on other sites More sharing options...

What happens if you just disconnect the D0 wire ( Your red wire ) from the mod-chip but leave the chip still plugged to the MB? Can you post a pic of the mod-chip component side? I would still like to see about 50% less solder on each joint ( use some de-solder braid ) and then it should look better.

With the D0 wire disconnected the chip shows a red light and my Xbox boots normal from TSOP flashed with Cerbios 2.2.1b.... Do you have any idea what might be going wrong? By the way, tomorrow I'll try to remove some solder (+-50%) with a desoldering braid (I hope I don't remove all the solder, I'm pretty bad at using it ) 11 hours ago, SS_Dave said: Can you post a pic of the mod-chip component side?

Maybe if you have another chipped Xbox, you could test it in that, or if you own another modchip you could throw that in and see if it works.

Check the voltages while the chip is connected to the main board and powered up as per this pic Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

This indicates that there is a disconnect between the Aladdin and the LPC header. Check continuity from pin 1 to that corner hole that read 0.02V. Also check continuity of LRESET (pin 5) to the hole that reads 0.21V. Quote Link to comment Share on other sites More sharing options...

SS_Dave Posted February 21, 2023 Report Share Posted February 21, 2023 Can you do a resistance test between the mod chip pin 1 ( the point that's reading 0.02volt) and pin 1 on the MB (the pin that was reading 1.7 volt) You will need access to both sides of the board. And if you can test all the other pins as well Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.
