A little feedback... I made a bootable USB drive of High Sierra on this machine. I had to: via Internet recovery wasn't possible anymore. Files were damaged on the server was the feedback. Because there're lots of programs not compatible anymore with HighSierra, I updated to Catalina from a...

original board has lots of interrupted ways. Especially in the area of the CD3215 chips. So this wasn't fixable anymore. The previous owner tried to fix this board by himself with no luck and lots of damage. I bought a secondhand defective board in the US (=cheap). This board had the short on...

Laptop works perfect, never crashes, but sometimes when going into sleep modus, this thing reboots and tells about Kernel Panic. It happens both on charger as on battery, but more often when connected on charger. Read some stories about defective Touchbar, but this Touchbar works fine. This...

Good news, this replacement should work. Thanks for the link!

I have this board from a macbook with flexgate (disturbed picture). Customer continued working with it till it gave no picture anymore. EDP_INT_AUX_N 20 ohms to ground with everything disconnected. External display works, so definitely a defective CPU. I have also a donor board from exactly the...

Nobody? At least no one who knows in which chip this Touch ID data is stored?

I finally received a donor board for my A1707 with broken ways on his board. Made one good board out of two, but off course the donorboard has been fixed. It's not possible anymore to setup Touch ID, although the power on/off feature of that button still works. Is it possible to pair this touch...

Good, looking for an SMC now. Ebay & China is great in this case i guess :sneaky:

I think you don't fully understood what I've meant. I asked: when in this board (820-00923) the RAM is defective, does it also beeps three times like an A1286 will do. It's one last "unknown" for me on this A1706 board: what does this when RAM is defective?

Ok, looking for another SMC. Don't have such a scrap board at the moment; have only an 820-00928 Last question before I'm looking for a donor board: on an eg.A1286 with defective ram, computer gives 3 beeps and doesn't do anything. What does this board do in case of defective ram?

Is this the same SMC as from a 820-00928 from an A1707?

Any other thoughts?

The only way I can get the Apple logo, and in verbose the EXITBS message, is with his original Bios file. In the mean time, I tried yours from yesterday. Board tries to boot, I've got backlight, but nothing on the screen. After this, again the reboots. It's exactly the same behavior as I...

While working on my A1707 with defective CD3215 chips (concluded later this board's copper ways are destroyed), I never managed to find out how Apple's original USB-C charger turns on... Does somebody knows this? When the charger has been plugged in, but disconnected from the laptop, or...

With disconnected J9600 I only can get the reboots without picture. In de past, I've got once a blinking question mark for 1 sec and reboot with a disconnected J9600 Connecting an USB with macOS and this J9600 disconnected doesn't lead to any picture. Nor while trying to pushing into recovery or...

isn't it possible to narrow it down? I've plenty of time to find this out. The owner bought already a new laptop. If you enter this "error code" in Google, it's very known in the Hackintosh world. But I can't find any real meaning of this in a real Apple computer. Maybe this could be a "start"...

Thanks, this gave me a clear Apple logo, so this screen should be OK. When I open the screen further as 90°, I can see the flatcables becomes tight. Although it's not happened already, this is still a "flexgate" screen. I will search for a good, or repairable board for the Macbook But is there...

When the board restarts, 0.6V becomes during 1sec 1.1V; 0.5 sec 0.9V and again 0.6V. 7 secs later restarts again. 1 sec 1.1V; 0.5 sec 0.9V and again 0.6V and so on and so on. (As previously mentioned does this board has other behavior with disconnected trackpad. eg Faster reboots.) So, with...

I've a nice case and LCD of a A1707 which contains a completely damaged 820-00928 board (some broken ways and copper pads becomes loose when trying to solder). I like to check if his LCD is still fully functional. When I connect the 820-00923 board of my A1706 (see previous topic) on the LCD of...

Hi, very first post on this nice forum. Read a lot here, but I've never seen something equal to my mystery. Hopefully it has a solution... So, after connecting charger, Apple logo after a while, no progress line. After 5 secs reboot and so on. Switching to VERBOSE mode gives more info (see...
