  1. So I picked up a broken xbox. Pulled it apart. Leaking caps everywhere. Cleaned it all up board looks ok. Got it to boot to error screen and decided why not try modox with prometheos to see better see what's up. Boots into prometheos but hard drive is toast. Can I pull the eeprom with prometheos tools without a Hdd?
  2. Hello everyone, Yesterday, I bought a Xbox (10€) at a flea market that stopped working after an EEPROM change. The console displays no image and flashes red. When I opened the console, one of the legs of EEPROM 24wc02j is replaced by a wire soldered directly to the motherboard, as the pad is no longer present. If I solder a modchip or a Pi Pico, will I be able to operate the Xbox? Have you a solution to bypass internal EEPROM ? Thanks in advance for your help.
  3. Hello, I have been trying to diagnose a no video scenario with one of my xbox that I originally thought was being caused strictly by a bad bios flash. I original posted some questions about it in flashing and bios forums, troubleshooting has lead me to believe that my main problem is now related to eeprom issue so I figured post should be here, as it is no longer relevant to those forums if that is incorrect and I should of just continued posting in one of those previous thread I apologize... This xbox originally had a dead hard drive so I tried to read the eeprom with ch341a and a test clip. Being 1.0 xbox there was not much room to fit the test clip and after many failed attempts I gave up with the clip. At this point I unsoldered the eeprom and read it directly on the reader, I obtained good read with no issues then resoldered the eeprom. I continued to flash the tsop with xblast and upgrade the ram to 128mb. ram test passed with no issues after many heat cycles. I proceeded to flash a new bios to the tsop, except I bumped the power at the end of the procedure got an incomplete flash with frag. I was able to test some of the other sections of the tsop with recommended 3 wire trick and the xbox would boot but with flashing green and no video. I tried bypassing tsop with Aladdin but again no video and flashing green. Thinking I corrupted the eeprom I desoldered the eeprom and verified contents match the backup, and resoldered the eprom. The last modchip I tried was xblast modded Aladdin and to my surprise the xbox boots with video like normal, I believe this bios is working because it is Cromwell/Gentoox based and is ignoring the eeprom. In looking at the eeprom, I can read and write the chip no problem off board but I cannot read/write it in circuit through lpc header.... when I hook up programmer through lpc I get a red light on the programmer indicating incorrect pin or short. I now think I must of shorted something out when fighting with the test clip originally. Anyone have any idea on what I might of fried or what area I should start looking? is there any motherboard schematics floating around? I'm not ready to banish this poor box to the parts bin yet if I can help it lol. again thank to all that have helped me.
  4. Hello, Wondering is there any bios that will boot and function without working eeprom? Thanks
  5. I successfully unlocked a hard drive with 500GB worth of xbox games and emulators on it. Now I want to lock it using the eeprom from my xbox so I can install it. I unlocked it using HDM V1.9 - I also have a second console if I need to use chimp. Any help greatly appreciated. Thanks
