Hacking OLED V6 Chip Black screen

[Hassal]

I didn't reflow the eMMC. I didn't think it was necessary anymore. When installing the small orange dat0 connector I slightly tinned the point and slid it under the eMMC and anchored it. Tested it and was a little over 0.400v from memory. I'll test it again when I pull apart the NS today.

Its kind of weird that your CLK would break under eMMC since you haven't reflowed. Most of the time its done by people wrong.

I reflowed my emmc with my heat gun raising the temperature every 1 min and used the following temperatures:
>160°C 1 minute
>250°C 1 minute
>360°C 1 minute
>400°C 1 minute

When my OLED was alive again. I noticed that the space in the emmc was almost full and I don't have anything installed on it, days later it died again with a black screen. Probably my nand was corrupt, but there is no problem since I have a copy of the emmc and if it doesn't work I plan to follow the guide of sthetix "DO A SYSTEM RESTORE: UNLOCK THE NSW"

Its always better to reball if you have issues since you won't be exposing the chip to the same high temperatures each time.

I suggest you make a copy of your emmc and prod.keys using hekate and lockpick in case it fails again in the future.

Where do you suggest I go to read up on how to do that? I find there is a LOT of info on the internet, but some is old and incomplete. A definitive guide would be useful.
