Hi everyone,
I'm seeking help with a CECHC Fat (COK-002 mainboard) that I'm trying to bring back to life. The console originally had a YLOD, and the previous owner had tried to dump data from it but ended up ripping off the pads.
Using a microscope and an X-Acto knife, I exposed alternative points and successfully dumped the data, edited the checksum, and even accessed the error log. So far, so good.

After this, I decided to perform a reflow. Using a heat gun (410°C / 770°F), soldering flux, and solder paste, I got to work. After partially assembling the console in the lower shell, it booted up perfectly. I restarted it multiple times, and everything worked as it should.
Bootup worked:

Then I proceeded with the full reassembly. But when I tried to insert a disc, the console suddenly shut down. Now, I'm left with only a red light – no YLOD, just a steady red light.
Video to the failure:

Here's what I've done so far:
Thanks in advance for your help and sorry for the "links". I guess my profile is too new to provide real links thats why i changed them because i think is important.
Best regards,

Here's what I've done so far:
- Power Supply: Tested four different PSUs – same result every time.
- 12V Line: Measured with a multimeter – 12V is output as expected.
- Cable Check: Measured resistance from the socket to the cable – all fine.
- Second Reflow: Tried again – no change, same issue persists.
- Heating up the Tokins for more trial and error didnt helped
- CRX AUTH: Authentication works, and I get Auth successful.
- EEP GET 3961 01: Output is 00000000 00.
- CXRF Commands: Whenever I try any CXRF command, I get the error: scopen response invalid, even when repeating AUTH.
- Swapped TX and RX multiple times.
- Verified all connections and re-soldered everything several times.
- Double-checked every wiring configuration I could think of.
