thanks, that worked.

Hello, I want to flash an EFI ,clear me, for a 2015 820-00165 (SN C17QL0YFG940) From the serial it is a 7,2 but here https://github.com/gdbinit/firmware_vault/tree/master/EFI/MacBookAir I can find only repos until 7,1 So what is here to do? for a hint i would be thankfull

yes, that was the idea, to have a working board and then take from the patient board, SSD Nands, CPU, T2 and WiFi Modul to the working donor board if all sucessfull should be work?

no, it stucks in almost half way in step 4 PP2V5_NAND_SSD0 is 2.53V stable all the time

i know that apple can save the data over dfu but i dont know anybody to send it there

yes, thats what i thought but now the short is gone. i need this come to work to save the user data if there is no chance can that be sucsessfull to take a working board and to replace the nands, the cpu, the t2 and the wifi modul? but that is riski and a lot of work. thats why i thought to get...

I used like I decribed above external switch method. Now by playing with the on off switch I am able to force DFU mode but the main problem is still the same it stucks in almost half way in step 4 PP2V5_NAND_SSD0 is 2.53V stable all the time

Still the picture with the 2 holes.

i found out that it is only needfull to connect the Accu and then short the SWK003 to force the DFU mode. but until now I allways only got the recovery mode. dont know how to get the DFU again?

Hi, got this device, there was a liquid spill on the Keyboard connector and a short, so I had to remove the connector and scratch 2 holes in to the board until the short was gone Now I have 20V and 0.000A. I found in the net that probably T2 not talking to the PMU correctly. PP3V3_G3H_SOCPMU...

is it possible to upload me one?

i dont can say anything about PM_PWRBTN_L and PM_SLP_S4/3 measuring during press PowerButton because PM_PWRBTN_L

tryed PRAM reset, but not better. it only turns on if i press the power button within 2 seconds 2 times. after 3 seconds the first led turns off and on again

I had the same problem and want to complete this thread PM_PWRBTN_L 3.41V and drops to about 0V by pressing power button PM_SLP_S4 is directly after plug in the power cord 3.41V PM_SLP_S3 is directly after plug in the power cord 3.41V as well all S3 voltages listed in the schematics are present...

still not,
