Nop, high, 11v8 and of course the QP800 stay close

in diode mode : .460 on I2C_BKLT_SCL/SDA screen plug .473 with screen unplug traces good on RP850/1/2/3 continuity ok on DP800 to RP831 and RP831 to chip.

hello, 820-02020 liquid damage on few spot, i have image. -FP800 ok -QP800 ok -PP5V_SW_LCD ok -PP3V3_SW_LCD ok -VIN ok on UP800 -BKLT_EN_R present (1.8v) -All trace ok on UP800 -Diode mode ok on motherboard pad UP800 -All resistances tested near UP800 and QP800 -2 good screen tested -Change...

So, i have to let it work alone ? Do you have an idea of time to wait ? Thanks

same problem with restore :( it start,on host mac, but nothing on target mac, black screen

Hello, I have a MacBook pro a2141 820-01700-a that doesn't boot, it goes to 20v, and charges. I tried to put it in DFU, it accepts. When I try to restore or revive it, it passes on this lock. Not being acclimatized to the t2 yet, I have a hard time figuring out what this means :/ thanks in...

sorry for the late reply, unfortunately the customer wanted to get the mac back and I didn't have time to test, but in my opinion it won't work, the programmers I have are all designed for iPhone partitions :/

I'd have tried xD thanks for your answer :)

Hello everyone, I just had an interesting breakdown (820-00239) The 4 CD3215C00's burned out, all had a burn hole on them. I changed the 4, one side worked ( loop on 5v ) the other side was blocked at 5v. On the side that didn't work, no LDO 1v1. After several tests, I changed the TBT ROM chip...

Thanks a lot for all your time, I go try next week or this week if i have time at work to remove NANDS and look if I have new results :)

Can i try to change it or this shit are serialized ? I have same NAND from iphone 8/X and programmer, maybe... or not ?

SSD1_VR_P2V5_EN present when i remove U9000, but when resoldering it, 0.00V ?

I already try this this morning, change u9000/80, clean and resolder all this area, check all resistor in this area too, same problem :/ If I understood correctly, I should normally have voltage on the nand, and from what I saw on the schematics, u9000 communicates by SCL/SDA with T2, so I...

Hello, So, after try revive and restore, error 4005, no voltage on any nand.

So sorry, i just have retry DFU mode, and its recognized ( this system is so creepy...) i try revive and tell you

Ok i go look for heating tuesday cause my IR cam is at work, meanwhile i go test voltages of SSD. thanks a lot for your time and see you on tuesday :) EDIT: no voltages at all on L9020/30/80

Thanks for help :) LDO rails : PP3V3 0.480/0.500 3.38v on all chips PP1V5 0.480/0.500 1.59v on all chips L9020 0.363 30 0.358 80 0.118 ( low i think :/ ) also i found that P3V3MAIN_PGOOD not present I go try dfu mode EDIT : impossible to go on DFU

Hello everyone ! First post here :p so i have a 820-01700-05 with cd3217, water damage near JB500, U9080, U9000, UB300, UB400 and around all this composants. Change UB300/400 with cd3217 from aliexpress... When i plug the charger, 5v 0.249a on all usb-c ports without battery plug, and 20v 0.00a...
