Just happy to help... Remember you can also use this command to clean the ME :-)

I just updated the archive to include a newer MacPro5.1 ROM. Can also be used on 2009 Mac Pro to enable High Sierra and APFS support https://drive.google.com/file/d/1smJIFatFgHetb9BUoRnF7hd-1EQmm5AC/view?usp=sharing

Your welcome. Saves a lot of time in the long run :-) Especially in cases like this particular one that only need APFS support activated. I know Duke (and several others in here) knows what to do. But to other people that want to play around with these files - be aware! Use the correct file...

Yup. PCH getting slightly hot. PPVRTC_G3H shorted to ground. Removed all caps on the line. Still 0.002V voltage drop to GND. Thanks... RIP

I spent the time already. Here are 10.13.5 EFI payloads. I am also using these for cleaning ME etc. Just put them on a USB installer and run from Terminal: bless -mount / -firmware "/EFIPayloads/<FILENAME>" --recovery -verbose shutdown -r now...

You can also force flash the EFI update. That way you save a lot of time with installations, updates and backups

Try running Passmark Memtest or equivalent third party memory testing software.

This 3435 came in dead. Upon opening i see a burned hole in the battery. Disconnected battery but still not turning on on AC. Checking PBUS is only 0.9V. Q7560 getting extremely hot. After replacing Q7560 PBUS is 8.6V but still not turning on. Now PP3V3_S4 is missing (along with S4_PWR_EN and...

Depends on what exact model it is. All of them can run 10.4 (Tiger) but only some of them runs 10.5 (Leopard) So download the 10.4 (Tiger) operating system on some torrent site, burn it to CDs (or DVD but only the newer G4’s has DVD drive), boot from cd by pressing “C” on boot up (or use boot...

I think the forced EFI update SMMRepair is talking about is by running the command bless -mount / -firmware <EFIPAYLOAD-FILE.fd> --recovery -verbose I once made a guide on Adv.Reworks-forum (my username over there is "supermac") about how to do it. Basically you copy the EFIPayload file to a...

Thanks. I am thinking about the "blaablabla"-part could tell something about it as it is displaying some memory adresses. But how to apply these adresses to a physical chip I don't know anything about at all. panic(cpu 0 caller 0xffffff802a1e4d90): "Possible memory corruption...

This one makes kernel panic as soon as it starts loading OS. It gives the error: "Possible memory corruption... blaablabla..." ASD EFI fails with ERROR - Data match failed in Memory test 9, 60, 61, 62, 63, 64, 65 and 66 I reflowed the RAM. Same issue. I am not going to replace 32 pcs...

I use the RT 1 when going small. It is 0.2 mm. But you can get a 0.1 mm. It is called RT 1NW which means it is non-wettable and thereby will not take solder. This brochure lists all available tips along with the order number that you can easily use for searching at Mouser or Farnell or other...

Measure if S0 rails go low after putting it to sleep. Check also VCORE while sleeping. Could also be a software issue so be sure to check with a known good OS you know for sure is sleeping correctly.

SMC_LID_LEFT = 3.37 V SMC_LID_LEFT_R = 3.37 V SMC_LID_RIGHT = 3.37 V (only with audio flex cable connected in J6600, otherwise ~10mV) HALL_SENSOR_RIGHT = 3.40 V (only with audio flex cable connected in J6600, otherwise ~10mV) LID_OPEN = 3.37 V LID_OPEN_R = 3.40 V

Yup tell me about it... Pins 44,45 have spike with both the screen connected and disconnected. Both LCD are working for sure because I have another 820-00875 that they work on. I have tested with three displays (two good ones and a cracked one). All three working on good board. None working on...

connector and probe points

Pins 1,3,4,6,44,45 have continuity to the other side of the LCD cable. I measured from nearby probe points as the LCD cable connected is making it impossible to measure on the connector directly

The caps are looking splendid and measuring between 80-100 nF in circuit. I get a spike once while powering on at pin 44 and 45: Pin 44: 3.30V for 600ms Pin 45: 5.12V for 600ms
