Aladdin pinout questions

Alright folks,

Of the numerous aladdin chips i've installed into 1.6 xboxes, i have installed the pin header with pin 4 removed, rebuilt lpc, connected bt->gnd on chip, cut the lframe trace at the xyclops chip and ignored installing the d0->gnd wire. This has always worked fine for me.

Recently i have seen different and conflicting instructions on de-pinning the header. it was suggested to also remove pin 3 (lframe), 6 (5v) and 12 (gnd).

I'm wondering what the benefit is and whether i need to start doing it this way?

I'm presuming pin 6 has been left out so standby power isn't lighting the led, and pin 3 to disable lframe without cutting the trace? why remove the second gnd (pin 12) though?

Just wondering what the consensus was on this, is this a better way to do it, is my usual way now incorrect??

Figured it was time to ask the experts!

Cheers

This I how I handle the Version 1.6 boards.

I use the Aladdin chip on all the version 1.6 board and I rebuild the LPC with wire links. On the Aladdin chip I link the BT to ground and I also change the LED power on the chip to run from the 3.3 volt that way the led is switched. As for the D0 wire I don't connect it and  I cut the LFrame trace.

The only reason to connect the BT and the D0 was for Xbox Live, and the only reason I switch the LED is a lot of customers liked it.

Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

Hi, thanks for the reply.

So just continue what im doing then and just remove pin 4 from the header, leave the rest? I take it all the 5v pin does these days on the chip is light the led, hence your bypass mod?

That right the 5 volt is just for the LED.

      I made a post a few weeks back about getting a 1.6 with a HDD that immediately died after booting. Couldn’t get eeprom in time. Looks like someone was trying to tinker around and really screwed some things up. Without the wires and chip, the Xbox will boot into HDD failure error which I’m fully aware of. I tried getting two Aladdin chips fitted and neither one of them will boot. They both flash green light for a second and then power off. One chip shows red light and the other shows yellow. I’ve reflowed solder points countless times and still the same result. I’ve tried D0 grounded to board and the chip and other various places I’ve seen and read about, but nothing works. As you can see from the board, there have been several trace lifts, but from what I’ve seen I have everything linked up properly accordingly to the lifted traces. Any help would be greatly appreciated. 
       
      I do not want to keep the chip inside so I have not cut the L-Frame. I just want to pull the eeprom and build a replacement drive. These Aladdin chips on 1.6 are proving to be a real pain in the ass.

      I just picked up an EMS Topgun II. Is anyone here familiar with it and able to give pointers?   I’ve figured out how to work it and calibrate it.  My biggest questions are how to do general navigation on Xbox and in CoinOps.  
       
      Id also like suggestions on good light gun games in both. I know about House of the Dead 3 and Silent Scope. I also have the Chihiro Virtua Cop and Ghost Squad

      Hi all,
      I've been out of the scene for ages, but recently saved a few xboxen from clock cap death and bought some aladdin chips to mod them with.
      Also got some SATA to PATA converters, which I haven't gotten working: proper 2 cap version with the master / slave jumper and an 80-pin cable, seems to cause a conflict with the DVD drive in every config I can think of - OGXBOX DVD shows "linux" and then DVD keep seeking back and forth forever. I thought I'd update the bios to see if that helped.
      I've gone through as many threads related to this topic as I can e.g. https://www.ogxbox.com/forums/index.php?/topic/3866-aladdin-flash-not-writable/ and tried the suggested solutions, but I am unable to flash a new bios to my modchip.
      I' going to try and provide as much information as possible as well as the things I've tried, in the hope that someone can assist.
      Top side of the board (this is one I haven't installed, installed one is identical with BT and D0 connected correctly, chip boots fine):

      Bottom side of the board:

      Stuck on erasing (and bios ID):

      Bios hashes:

       
      I'm using OGXBOX Installer 2021 DVD.
      Xbox is reported as 1.4.
      So I've tried the following:
      xflash for sst49fl020: seems to be able to dump the flash, but fails on flash with an "Flash check id failed, are you sure you have flash enabled?" XBlast 0.56: select evoxm8_67. when I press both triggers, start and white, the xbox reboots (wtf?) OGXBOX menu flash: gets stuck on erase as per the image above Tried the short and long power button presses, doesn't seem to change anything. "Chip: Protected" appears on the OGXBOX screen Any suggestions? I do have a minipro programmer somewhere with (I think) the correct adapter so could try that as last resort.
      Thanks
