Hardware Hardmod o3ds xl - help me

[Ps3nucleous]

Hello everyone.

I was doing hard-mod to the old 3DS xl, I soldered the 4 points correctly and everything went well (I plugged the SD to PC, they left 2 blue screens and i make a copy nand ok. Then place another copy to patch). I checked the offset 100 that went right with the letters NCSD and proceeded to write the patched nand.
When process ended, i turned off the 3DS. When i turn the problem occurred. The bottom screen can not see anything, has the reflection shine as if issued video and touch works, but is not visible at all. But i move by the applications menu as well if I displace the menu on the lower screen appear.

I tried to rewrite the original nand that I found that was correct and the fault remains the same, black screen at the bottom ... I have reviewed each flex and does not seem to be loose ... Also i change motherboard with other 3ds that all its ok and problem repeats.
What do you think can be mistake of writing? Are copies of the original Nand corrupt?

I add that the error appeared to me on blue screen it was:
BOOTROM 8046
ERRCODE: 00F800FF
0F0FFFFF FFFFFFFF
00000020 00000000

Greetings and thanks.
PS: sorry for my bad English

Its ribbon related. Check your ribbons.

I'll check it. What error code should appear? Should I return to make a copy of the nand, patch it and write it again? I am now something lost sincerely
Thanks

If nand was bad, you would have blue screens without the adapter hooked to pc in most cases.

You evidently damaged a ribbon. Not sure how as on that model the mb dont need to be removed.

When I turn on the 3DS, appears 3DS menu but the bottom black screen. I can enter settings and all good and I can even enter hombrew launcher with oothax and downgrade to 2.1. But the image of the bottom screen can not see anything...
Can i solve it writing patch nand again after checking all ribbons?

Its not nand related. Look for solder splash.
