Hello I'm having an issue successfully flashing a split Tsop using the xblast lite modchip. I've albeit believe I've successfully soldered d0, a15 and A19 to the modchip. I can see the split in xblast os, I can boot either split but it currently has a 1mb cerbios 2.02 on there. I can boot either bank from the modchip. My issue is with tsop_m7, I flash this to the 256k bank of the modchip and proceed to boot with hexen inserted that boots off the other bios. I get no display and a solid green lights, eventually the Xbox power cycles back to xblast os. I've also tried setting the front switches to boot the 256k bank on power on same issue but it'll power cycle every minute or 2. I've tried setting xblast os to boot bank 2 with the power button. Same issue The option "force tsop recovery" has been set to both tsop banks - no change I've also tried tsop_m7 on the 512k xblast lite bank - same issue I'm stuck, not sure what to try next with the exception of shortening the a15 wire as I know I gave it too much ( approx 8 - 10 cm) but would rather not mess around with it if it's fine. Thanks for reading, any help is appreciated

Dear, all Xbox fellow I had a spiderchip since 14 years ago for my xbox, which is still working. ABout 2 weeks ago, I wrongly flash 512kb bios into my xbox (1.1) TSOP (1mb), causing it unbootable. I was trying to find a way to recover the TSOP, and one way was to use a modchip with special bios "tsop_m7.bin" for recovery. So I did flash the spiderchip with tsop_m7.bin. But I forgot my DVDROM is not working, so this method is not workable. And eventually the TSOP issue was resolved with "3-wire trick". Now, the spiderchip is left useless without normal bios, and it seems the guaranty way for recovery is to use external programmer, which I don't have and don't know how to use. There are some forums discussed quite good success of using modchip hotswap, and even Softmod to flash modchip (NOT TSOP). So I decided to use most cheapest way - softmod - to recover my spiderchip. But as my Xbox 1.1 mobo is soldered for TSOP flash, I don't want to revert back to stock status. I remember my cousin has a Xbox 1.5 (softmoded) which has not been used for long time. Borrowed from him, still can turn on, BUT ERROR 07, reconnect/changing IDE cable didn't work. Changed to another HDD, Error 06, obviously it should be the HDD issue. My cousin doesn't have eeprom backup in PC, but he is quite sure it was backed up inside the 8G xbox HDD (WDC). So I tried many times to do HDD hotswap connected to my laptop through USB-IDE cable and XboxHDM (Windows version), no luck, the Xbox HDD lock status is alwasy enabled. NOT sure it is because of wrong timing or USB-IDE problem which may trigger the HDD to relock. In actual fact, the easiest way to access locked xbox hdd is to use modchip, but the spiderchip is useless with tsop_m7.bin bios inside. Out of sudden, I was wondering, Can this special bios be used to re-flash the modchip? According to the steps in https://assemblergames.com/threads/1-0-1-5-tsop-recover-bios-tsop_m7-bin.54493/ , A15 & D0 need to be removed in sequence in order to activate TSOP, but I am not aiming at TSOP, so I don't remove the A15 & D0, Should it work to re-flash the spiderchip? Anyway, I have already tried last night, and I am facing the problem to boot to the Orange Xbox logo (tsop_m7) on this Xbox v1.5. Previously i had nearly no issue to get the orange xbox logo on my xbox v1.1. when chip-in with this spiderchip. The v1.5 Xbox remains with black screen for 1-2min, then shutdown and reboot automatically, However, there about 3-4 instances, when I can see the orange logo, ONLY BY slightly lifting the spiderchip off the board (then re-seat?). But that is not always working. Out of this 3-4 instances of seeing orange logo, only one instance could move to a new blue screen saying the xbox hdd need to be formatted, do you want to proceed? Surprisingly, it is not HeXEn DVD main menu, which I am expecting. I understand the spiderchip is solderless, which is not stable in terms of contact with LPC, But I am quite sure that, as long as using my finger to press the chip into the LPC, the spiderchip is working perfectly, But why is so for xbox v1.5 , do I need to shortcircuit or ground some points Peter
