hi, could u tell me is there any difference. the supplier said its for different laptop models. in the schematic i found only CD3217

SSD0_VR_2V5_EN = 0V is this not a part of the problem? what does the restore/revive needs to work? where does the ..installing the system... installing the system and which system.

yes you are right. ok so I tried that revive and restore is the same result. both have just in the moment when the message comes installing system.. the drawing ampere jumps from 0.200 to 0.400 then after some time end it up with pictures I posted already

no only revive. the client needs the data. restore cleans it up I think?

PPBUS_G3H_SSD0 is 12.22 SSD0_VR_2V5_EN = 0V I measure with the scope the I2C"4" (I2C_PWR_SCL/SDA) but this is only 1.82V seems no try of communication there, in diode mode both have 0.454

no, found some pictures in the internet but there is no resistor. It represents (R4710-4715) the board ID tryed again to solder the soc rom with your datafile, now it shows me the dfu started to revive the machine but same result, stuck on 1/3 and switches from 0200A to 0380 A 5.11V but now its...

I just see on the board there is missing R4710. is this all time so or i blow it away? I dont have another board for check this, in the schematics no advise to find

i tryed that but the same result, 5.15V 0.200A but DFU on the master not to "see"

I flashed your file into a new chip, soldered it on the board. then i had 5V and about 200mA seems to be in DFU mode but in configurater not to "see" so i flashed the backup into a another new chip and soldered this back after that same like yesterday, 0,400 in DFU 0,200 in DFU to "see" but...

thanks. I will report back after that. Is there any other step needful? or only backup the T2 Rom and flash it with your file?

in the repair wiki i found https://repair.wiki/w/A2251_2020_13%22_MacBook_Pro ...PPBUS_G3H ~12.28–12.35 V = T2 communication issue with the ISL9240. The likely cause for this is the device is stuck in DFU mode due to corrupt T2 firmware or a failed CD3217. Proceed to repair steps below for...

ening up with this (reviving)

thanks, i flashed that and soldered back still 5V and 400mA but now i can "see" it in dfu mode already. but reviving device stucks on 1/3 of the way, while 5.11V and 0.375A need realy help

found under U3060 one leg missing because of corrosion i have a programmer and the same part from a a1708 from where i can get the data to flash?

yes, but all i do i dont get into the DFU mode maybe its a DFU mode because i have 5.19V and 0A, after disconnecting the TB-Cable it start to draw 0.400A like before but in the "DFU" mode i dont see the device on the master Mac

foud burned R7900 like in repairwiki described "... If PP3V3_G3H had a short circuit, but the board stays at 5V and PP3V3_G3H is still missing, it can be due to R7900 (0 Ohm Resistor between PP3V3_G3H_RTC and U7800 PMIC, that takes PP3V3_G3H_RTC input and outputs it as PP3V3_G3H). Short...

on all 4 ports the same PPBUS_G3H 12.26V PP3V3_G3H is missing short to GND in PP3V3_G3H via thermal camera and injection of 2V found damaged C7807 i pulled it from the board, the short is also away, in diode mode i get L7660 Pin 1 0.413 was 0,0 board back in the case with accu, no...

no idea... PPDCIN_G3H is 5V, PP3V3_G3H is 3.3V PPBUS_G3H is 12.26V 400mA its still without DZ3300_CXT and DZ3303_CXT

ok, replaced but nothing changed R3109/08 has now on Pin 2 .528

found here a hint https://boards.rossmanngroup.com/threads/a2251-820-01949-a-no-power.63508/ checked R3108/09 and found under R3109 pin2 korosion. will change and report back
