Firstly this post should really of gone in the ...
"All other and alternative modchips and cheapmods" (Sorry
)section. OK so both xbox's are V1.6 and you have 2 aladdin xt modchips well the aladdin xt chips are very good for older xbox's but they are not the best for V1.6. Did you connect 2 wires to resistors near the front of the motherboard and connect these to the chip L1 and BT ?(YES I DID
) if so then a quick press on power should start the xbox in normal MS BIOS and it should work ok for originals.
You probly did not need to flash the chips at all since it booted ok before you flashed it. The main reason for flashing is to flash a bios thats compatible with a V1.6 and since it worked anyway it allready was. The problem with the first xbox is well known and its a problem with the aladdin xt modchip and the new evox m8 plus V1.6 bios and there is not much you can do about it. If you have a V1.6 and not V1.6b then Evox M8 V1.6 (not plus) might work more stable for you. But if you have a V1.6b then you will need another modchip like the Duox2 for it to work 100%. It will work as you have described but it can take many times for it to boot. Try flashing the original one with the Evox M8 V1.6 bios and see how it goes.
The second xbox you did must of got erased but then the power went out so it never got programmed. The only way to fix this is to reprogram the SST chip. One way is to use an external programmer but if you don't have one then just remove the SST from the socket and remove the SST chip from the other aladdin xt from the first xbox. Now put the good SST chip from the first xbox into the socket on the chip in the second xbox and it boot it up with the lid off and the dvdrom drive connected but turned around the wrong way. Now while the power is on remove the sst chip using a toothpick or something else ( not metal ) and replace it with the dead one. Now simply flash the SST chip again i would suggest the Evox M8 V1.6 (not plus). (THANKS, THE PROP IS THE BOX WON'T START AFTER THE POWER LOSS
I REMOVED THE CHIP AND ALL WIRES BUT STILL WILL NOT START)
You see the latest Evox M8 Plus V1.6 bios is excellent for both V1.6 and V1.6b xboxes but it is not compatible with the aladdin xt modchip so allways use the Evox M8 V1.6 bios with the aladdin xt modchip also if your ram chips on the motherboard are samsung then you have a V1.6 and if they are Hynix then you have a V1.6b
