Help - Weird Oled issue after chip installation

[QuiTim]

I am having a weird problem after hwfly (oled) installation.
When i try to create emummc screen goes partially green (see attached) and then after a while it freezes.
Everything seems to be ok, checked all the values on solder points and everything else I can think of.
Changed the dat0 adapter 2 times.
I'm using 36awg wire.
OFW works great.
Any ideas?

Problem is your LCD cable.

Problem is your LCD cable.

That's the first thing I thought as well, but it works great in all other situations, I can play games, smash it around or do whatever I can imagine and no problem whatsoever. The moment I try to create emummc it starts ok, goes to 4% or 20%max and this starts to happen, then after 10-20seconds it freezes.

You tested the SD card?

So just for the archive...
I ended up desoldering the flex cable and rewired everything manualy.
Used 36awg for 3.3v, GND and RST; 38awg for dat0, end enamel magnet wire for CLK and CMD.
I also noticed quite some flux under the flex cable (which i removed with alot of difficulty) so this might have been the issue.
Anyway, everything works fine now.
I would still love to know is anyone faced same situation/problem and did they manage to pinpoint the exact cause.
Cheers.
