Purple screen on Mariko V2 with SD card in after changing the Modchip

[ThaRizzah]

So i got my Mariko V2 Switch back in february already modded and working, and back in august i saw the back plate had a bump and got skeptical, so i opened it and saw that the USB-C port from the Picofly RP2040 Zero modchip wasn't removed. I had experience with soldering before and thought it would be an easy fix, until i removed the usb-c port and a resistor broke off accidentaly from the modchip and with that i also broke the Lcd Fpc Connector latch, and because of that the modchip didn't work anymore , so i ordered a new HWFLY RP2040 and a new Lcd Connector both from Aliexpress.
When they arrived i installed the modchip and thought it would work without changing the Lcd connector, turned out it didn't, so i took the switch to my local electronics repair shop.
When the switch was done, i got it and turned it on and saw the "No SD Card" , and i got happy thinking it'll work, turned out it DIDN'T AGAIN because when i inserted the old SD card with the files and everything else i got a weird Purple screen with little black bars that i've never seen before and didn't found ANY information online, so i changed the SD card with another one i had, it didn't work. I checked all connections on the motherboard to see if everything is damaged, everything looks alright. I tried to enter maintanance/safe mode, i get a blue screen. And while i'm finishing this bigass "essay" i'm asking for help from ANYONE who can help me find what and why causes the Purple screen i also added images with the motherboard (where the old points of the picofly rp2040 zero were), the old Picofly RP2040 Zero chip, the V2 connector on the CPU and the HWFLY chip

so it shows the purple screen as soon as it boots up with sd card installed? does it enter hekate at all? try another payload like tegra explorer, lockpick rcm and see if they boot up.

what happens if you boot it without modchip? just conect the emmc module directly to the motherboard? There are some cheaply designed rp2040 chips that will cause interference on emmc data lane and result in black screen/emmc corruption

tried with tegra explorer and lockpick rcm, they restulted into a black screen, but it did say "failed to open payload.bin" before i edited their name into payload.bin but i don't think it helps with anything, and i tried turning on the console without the modchip and with the emmc connected directly to the motherboard and it resulted into a blue screen
does it mean the emmc is corrupted?

oh no not the blue screen, it could be caused by many things, including bad m92t36 charging ic, bad ram chips or even dead soc, unlike purple screen which is always an emmc problem.

since you paid for a shop to do the modding/fixing, just take the switch back to them since they clearly broke something when replacing the lcd connector cause your switch was working before

well if i get the "no sd card" screen with the modchip it means something works, right?
also i got the console already modded, but i'll replace the lcd connector again because the screen is sometimes fuzzy in a way
if no one finds what causes the purple screen i might go to the guy who modded the console to mod it again
