Sorry, didn't read your previous message, the Macbook wouldn't enter DFU mode

It was pretty fried anyway so maybe the damage has already been done? I don't have a donor board for this model, I may have to write it off as a non fixable.

Can I just run a wire for L8300 or could you suggest an alternative from any board <2017? Have I potentially damaged U8100?

Yes I did, I have no scrap boards available with a similar coil. I farmed L5001 from a 820-00840 3V3_S5 line

This Macbook came in with customer stating they had powering/charging issues with one of the ports, now it won't power from both USB-C. After replacing both CD3217 chips and still getting 5V 0.016A I checked the surrounding caps around them and found CF400/CF500 PP3V3_S2 low at .560V. On further...

I've reflowed everything on that side, still no joy. I'm awaiting new CD3217 but I feel I'm wasting my time on this board now. Would it be worth replacing ALL the CD3217s? I only originally replaced the two on the side where one was faulty/getting hot.

No, wont work with battery now, I had 20V before and after reflashing with the dumps you provided, with the original I now get 5V

I reflashed the 2 TBT ROMs, I get the same error message when attempting DFU restore although 5V 0.270A is now showing.

OK, I attempted DFU restore with original apple charger and Thunderbolt 3 cable, all I get every attempt is: 'Gave up waiting for device to transition from DFU to DFU state [com.apple.MobileDevice.MobileRestore - 0FCA (4042)] . Target Macbook is at 20V 0.066A most of the time. Should I reflash...

Not charging, not booting with battery... I'll speak to the owner with regards to data.

Hi, I reflashed UB090 and U2890 and now I am getting 20V 0.065A on all ports with and without battery connected. The Macbook will not boot at all now.

Changed CB300 with same outcome. I have ordered some USON-8 templates from PCBWay, do you have a dump for U2890/UB090 or know of firmware dump source?

OK I'll try another CD3217 as I have just received another batch. The Macbook works with the battery.

Hi again, sorry for the crappy formatting... UB300 UB400 UB3100 UB3200 PP1V5_UPC_TA_LDO_CORE 1.577V 1.570V 1.576V 1.570V...

Hi all, I'm new (posting) to the forums so please be gentle. This 16" Macbook came in not charging, was running on battery but all but one USB-C port were registering voltage of 20V 0A. UB300 was getting warm and showing 5V/0V on each side of its USB-C connector. I replaced the CD3217B and now...
