help me with failed oled modding
i modded my switch with kamikazi method first i accidently cut the dat0 trace the console didn't boot at all just black screen i manage to put small solder blob to bridge the cut trace and checked in diode mode to make sure its not shorted the console boots i soldered i wire to the ball and confirm it still boots i put solder mask and rechecked it still boots then i installed a picofly first it booted to hekate but when i checked emmc info it gives error emmc running in slow mode 0mb/s this might means a hardware issue then failed to int storage
when i try to take back up it gives failed to inti storage
no boot from hekate when i disconnect both ribbon cables off the Pico fly board "still connected to to cpu" it gives me purple screen
checked the resistor close to kamikaze point in resistance mode it gives 4.5 or 4.7k as i remember
i also went to pro cell phones repair technician to check the trace he did it and repair the trace but same issue boots to hekate with failed to int emmc
any suggestion what to check ? did my emmc dead ? i don't have a back up
plz any suggestion may help

update 1: i rechecked the resistor it's blowen i don't remeber if last time i checked was before or after i soldered the ribbon cable now i dont have a 4.7k resistor to test but i found 4.6k on old borad i dont know if i should put it or i will risk fry somthing did anyone put a lower value resistor and it worked ?

update 2 : i fixed it. it was just the resistor, somehow i though i have measured it after i install the ribbon to the A point but i didn't i measured it before the ribbon
ty everyone i will leave the topic in case someone faces the same issue
you need to replace the cmd resistor near on the A point the value is 4.7K ohms size 0201 it doesn't matter the size if it's slightly bigger just solder one leg side way and run a jumper wire to the other point that's what i did

i checked emmc info it gives error emmc running in slow mode

If you damaged one or more data lines to the emmc, you will get this error.
But you should be able to boot into Hekate and check if it is running in 1-bit mode (slow mode).

Another issue might be that you need to add some extra resistor.
That depends on which brand of emmc is used in your Switch.
Just post all your details in the Picofly thread :

I Checked the 4.7k resistor and it wan blowen i hope that is the issue and my emmc is still fine i dont have a resistor to relace for now i found 4.6k on a doner switch v1 bord i dont know if it fine to solder it shorting 100ohm or not i dont wanna risk fry the emmc if it is still ok
what do you think ?
