Hi All,
I seem to have an issue with an OLED right now..
The system boots to OFW without issue but the error code I'm getting on the picofly is =*==
(eMMC test failure - read failed)
My DAT0 point went perfectly. Reballed so no adapter. I'm getting a diode reading of 700 on the DAT0.
Full list of diode values are:
RST .000
CMD .701
CPU .270
3.3v .729
DAT0 .702
CLK .714
GND .000
Does anyone have any ideas?
Edit:
I'm wondering if I need to add 100ohm resistors instead of 47ohm but I believe that's advised for solving slow glitch times rather than the issue I have.
Otherwise, I'm thinking that maybe I need to reball the eMMC again..
Ok so I'm a bit lost with this one so I removed the chip and all wiring.
I've just checked the tiny caps on the APU and the almost the entire row is showing continuity accross the caps.
I've turned the board over and found that many of the big caps on the other side of the APU appear to be shorted too.
I'm confident that all my solder work went according to plan while installing the mod so I'm a bit lost as to how this could've happened.
Is this a dead APU? If it is then I can't understand how that could happen during a straight forward install and I'm hoping someone can point me in the direction of a fix.
I haven't tried re-assembling yet but using a USB-C power tester on the board it shows approximately 15v and 0.00A.
