820-00244 turns on but screen shows noise looking colors and freezes

[No-Clean]

Clean Mac no water or drop damage, starts up but after a few seconds it freezes and the screen looks like an old TV set.

Dead CPU like every other 12? lol. It?s unfortunate but true

Man what a luck, all I got today was 2 dead boards, sad...

 

[No-Clean]

Any suggestions on how to recover data on this machines? Transfer NAND to a good working board? Is there a NAND reader that connects to USB or something like that?

 

[2informaticos]

You should swap NAND, controller and also SSD ROM.
Not worth the job for less than 500?.
Think that you can end with 2 (two) dead boards...

 

[JohnB8812]

You can try as 2informaticos suggested or try reflowing/reballing the CPU. This will only be for data not long term use, but some have had success

I know people who revived such boards using IR oven.
But nobody confirmed how much time last these boards.
Should be good enough to recover data.
I would NOT give warranty for entire board after such process...

 

[No-Clean]

I figure out that only if the board got hot it shut down, so I came up with a cooling idea and got all data out.

Thanks for all the help.

In fact, these boards die because of "no fan" Apple design!
