Hacking [help] first time modding oled with rp2040 didnt work

[ash_ketchup]

sorry for bothering you guys





here are images of my kit and most of soldering points and video of boot

long story short:

read and watched a lot of videos before doing, i chose 3 as reference (sthetix, darkguy2 and 'fixing modding building' channels) is there any chance of know what is wrong to avoid resoldering ALL points? maybe i missed 1 or 2... this LED pattern of my video means something useful? (looks like purple then yellow on camera, but for me is blue then green)

here my measurements in diode mode of my multimeter (according to sthetix i should have 0.600~0.900v)
- 3.3 755
- D 1326
- C 646
- A 1344
(and this B point should be 0~2.9v)
- B 1321

i think D and A are not good, right? is there any thing to try before removing everything and soldering again? i appreciate some help. pls dont bully me

some additional info:
- im not skilled and never did something like this
- i screwed dat0 adapter but i think i found a workaround
- i didnt have awg36/0.1mm wire i used a thinner one i think
- according to reviews on ali the chip (rp2040 V4 V5 flashable) is pre flashed (but i couldnt recognize on PC to check or update)

Yes D and A have a wrong value. Check solder point or resistor value. A resistor is 4,7k
