Was fixed after replacing power button and entering dfu mode by normal way. Not force dfu... Problem was while power button was pressed(because of power button of 16" was installed) installing Mac OS... So there was no hardware issue only de firmware or boot partition was trashed. Everything...

Any help?!?

To bad, DFU restore did nothing! I looked like everything went well. Untill I Saw the Apple logo. In one sec it restarted again and after 3 restart again the support.com/applestore logo... Any other suggestions???

Was looking how to force dfu? As the power button cable is broke? Which pad do I have to short to force DFU manually on the logic board? Never mind, found it already! SV100, short pin 1&2 or 3&4...

After connecting the cable the wrong way I reinstalled osx. All the way to last restart then when it restarted it went to startup options (because power button is continu been pressed) when I was choosing the startup disk it couldn't select and I had to put the power off then I disconnected the...

Yeah it starts when I connect the power but problem is that it shows apple logo and in 1 sec it shuts down and does that 5 times before apple support logo. So I can't boot... Or anything?!

Also, now when the logicboard is out of the enclosure and only connected to the amp meter. It looks like it's booting but after 15 sec turns off and restarts this proces.

Hi, got this a2442 with a broken screen. Was working well only screen cracked and power button not functioning. The previous repair shop already opened it and cut the flex cable of the power/touchID button. I wanted to test with a powerbutton of a 16" a2485, looked like the same in the...

By some miraculous reason it works now. Al this time I was testing it out of the casing only with a screen connected. I removed RP842 and forgot the put it back. When I put The logic board back in the casing it worked?! Only some times de screen stays black until the login screen comes. then...

Hard to find these kind of scrap boards... Thxs anyways

Was afraid of that... Is there a way I can get a u8100 anywhere? Rossmangroup store?!?!

Back at it again! Was on a holiday. Got my small LCD cable but still no luck. Now im thinking this was the problem all along... But while I was looking somewhere else I destroyed something! I noticed that RP842 pin 1 has a diode mode reading 0.019 and 0v which was 0.187 and 0.8v. But should...

Let me order one, was thinking every flexible is the same but now I have my doubts....

Could not see anything extraordinary on UD050... Figured out something else! On the small lcd flexcable pin 24 is broken. On the connector on the logicboard I get a good diode measurement (0.507) but when I connect the small lcd flex cable I get a O/L on the other side... So the LCD doesn't get...

Tried but no luck! What I noticed is that “RP851 starts with 5.1v as soon as image apears goes to 4.8v” this is not 4.8v it stays 5.1v. but the scl line still starts with 5.1v and goes to 4.8v. So as I understand there is no good communication… What can I look at more?!?
