Hi 2informaticos, No worries at all. I am actually very sorry to hear that you are in the hospital. I hope you are fine. Thank you for doing it.

Hi, If you are back and can help with it, please do. I am getting lost with these new ME/PMC stuff and Piernov's video is obsolete with the newer chipsets. I've followed the guide on WinRaid for CSME v12 and had an cse_image_fwu_base.bin but I don't know what to do with it. I understand you...

The iMac model is iMac19,1 but I can't find it in https://github.com/gdbinit/firmware_vault/tree/master/EFI/iMac Any idea where I could get a clean ME region for this iMac model please?

Well enjoy your holidays then! ;-) The shop said they have put back the original Bios dump. If you are busy and can't do it, maybe you can point me a link which explains how to do it?

Ok I will get my customer to call them and ask, then report back. What if I can't get that information or at least know the truth?! I understand you don't want to reuse the Bios from a machine that is currently being used and I'll make sure the SN matches the one under the case if that makes...

Hi, I have a customer that came in with an iMac that is restarting in a loop. The iMac was previously repaired by another shop and I can see the Bios has been reworked somehow. The customer has reported that the loop happened after he tried to install an SSD in place of the HDD. Since then the...

You mentioned here (https://boards.rossmanngroup.com/threads/820-00928-stuck-on-5v.61038/post-74409) that if I can get 20V when battery is connected, the USB-C circuitry should ne working, therefore I should be focusing on U7000. Does that still apply?

I did replace the resistor and the signal is still pulled down. It did not make any difference in terms of voltage on the SMC_USBC_INT_L side. Those 4 resistors are measuring as they should. I am getting around .53V drop on both SMBUS_SMC_4 SCL and SDA signals. Measuring .63V on known good...

I went ahead and replaced one more time the SMC with a good known SMC and same behavior. So my guess is that it is CD3215C00 related now since that signal only from the SMC to those ICs?!

Unfortunately it didn't make any difference doing the SMC bypass I've checked with the thermal cam and nothing seems to be warming up. The only area on this board that looks pretty corroded is the right wing (underneath) where the T1 controller is. I've removed every corroded capacitor and...

P_IN 5.14V AUX_DET 1.27V SMC_RST_IN 3.4V TBA_VDDA 5V TBA_ VDDP 5V SMC_RST 3.4V IRQ 3.4V AUX_OK 3.4V AMON 0V BMON 0V

I went ahead and replaced one more time the ISL from a donor this time. No change. The resistor connecting SMC_USBC_INT_L to 3.3V is measuring fine. (I've checked other thread talking about a blown resistor)

I am getting the 3.3V at the coil. The SMC_USBC_INT_L is quickly jumping at 3.4V then right back down at 0.08V then 0.04V and stays there.

Yes it is the original 87W charger. Tried both the customer charger and mine, same thing.

820-00281 Not charging, 5V 0.02A on charger only (battery unplugged), 20V 0A with battery plugged, shows sign of battery flat. Should be a simple problem to fix but... Each USB-C port shows 5V with 0.02-3A consumption. No port power cycles. When checking rails around the USB-C chip, I'm getting...

I believe I do. I've checked around U7600 and the only coils that don't have voltage are L7821 and L7822 which are for PPVCCPRIMCORE_PRIM_REG I've tried again to get the machine to DFU and all I can see is the amperage going from 0.3A to 0.08A but machine does not get detected. I've tried using...

Hi, I have that 16" 2019 board which won't turn on. It's stuck at 5V 0.3A on any of the 4 ports. I am the 2nd tech working on that board. Visual signs: board is clean, no liquid damage that I can see. CD3217 have been reworked (reflowed or replaced) by the previous tech. With battery...

yes it was reporting percentage. I've tried with a new battery and it's working. Wondering how come those dies like that, in a such period of time?! My battery was working 3-4 months ago, board was dead (shorted NAND), customer didn't want to replace the board, sold me the Mac for parts. In...

Hi, I've got that MacBook Pro 16" that came dead. Wouldn't wake up from sleep. After first inspection, board would not start, was getting 20V but stuck at .04A floating. Tried reviving/restoring but got Error 6. After further inspection, I did find some signs of liquid on one edge of the...
