Hello! Currently having this issue:

just drop it in the rp2040

I used the "2.5 + unlock new.uf2" file. I just dropped it in and installed it.
Should I solder the usb again and reboot it?

if u dont have one i would suggest u get this one

UNI-T UT658​

u dont need to pay someone to teach u youtube is ur friend

Thanks. Found it. Will order now. Assuming that it does get power. Can we shift our attention to the NAND? Since all the work was done on it. Any idea what could happen to a NAND that would prevent it from booting? I reflowed it but no luck.

Whenever I add something to the RP2040, the computer stops recognizing it. How can I flash the 2.5 and then unlock?

That is normal behavior
Push boot button plug rp in
Flash 2.5nw
Redo above and flash unlock

After each flash u should get a red led light if its green u need to set rgb mode

Should the 2.5nw file stay inside after plugging the usb for the first time? I added the 2.5nw and then did as you said but there were only the index and info files. Is it also normal behavior?

Which is safer, stick to 2.5, go with 2.6 or 2.61? OR wait for 2.7?(not yet installed since flex cable is still beig delivered)

Yes, that is normal behavior, after you flash it the window will disappear and you will never see the file there.
