Thanks for your reply, do you have some informations about secondary power supply ? I work on windows laptop, mac is a bit different ^^ Thanks

Hi, Successfully reball U8100 and U7700. There was not oxydation under these chips Nothing more, still pulse

Hi, sorry for late, need to do some other stuff for customers. // means that this is not on the boardview, and not connected in schematic So PPBUS_AON is 12.291V Stable For U7700 LDOs : Input LDOs PP1V2_S2_SPMU connected to PP1V2_S2 : 1.2V PULSE PP3V8_AON_SPMU_LDO1 : 3.8V STABLE...

Hi, On this motherboard there was liquid damage. Pin 6 of UR200 was not connected Remplace RF242 too. Now I have 5V 0.02A on the USB C meter with USB C port (cause magsafe charger no light). Amps goes to 0.16 when pulse. Voltage I have : LDO of CD3217B12 PP1V5_UPC0_LDO_CORE 1.5V...

No history for this mac I will edit, yes I have all SSD Yes recognized in DFU. I did the short of SE032, tried to restore, it goes to step 4, approx 33% and stay. After 30 min I canceled the procedure

Hi, Have a A2289 who doesn't start. From USB C, switch from 5V to 20V and stay at 20V, but with 0.1A. Voltage I have : GENERAL PPBUS_G3H 12V PP3V3_G3H 3.3V PP5V_G3S 5V AWAKE PP3V3_AWAKE 3.3V PP1V2_AWAKE 1.2V PPVDDCPU_AWAKE 0.75V PP1V8_AWAKE 1.8V PPVDDCPUSRAM_AWAKE 0.8V SLP2R PP1V1_SLPS2R...

You problem can be here. You have 128G nand, or your configuration is 6, so you need 192G NAND.

Did you have tutorial for this tool ? Because I checked the software JCID Repair, and there is only 2 options for my mac. No option for the 2,4,8 TB for exemple. Did you already used it ?

Thanks for you reply, I can order other capacity so ? 4TB for exemple ? Ok, will check it so ! For you, is it important to have P13 in your tool ? I edited my posts

What is 01700 SSD ? And where did you find this reference on my chip ? I would like to decode the number written on my SSD to know the name of the chip, etc . If you have any idea?

Will check video later thanks :) Pre-programmed NANDs that's mean I don't have to buy P13? My board is a 1TB so 6 NAND. I have 4 dead NAND :ROFLMAO: Here is my NAND TSB42280W3197TWNA12006 Just checked the video, this is incredible ! Did you used P13 to do something like this ?

Many thanks for your reply ! In my donor, it seems I don't have these capacity. I checked with the capacity written on the box and after with the BOM. Do you have any advice to check capacity of the NAND ? I'll try to buy new one, do you have advice too ? I will buy P13 too :)

Hi all, I have one SSD side of the motherboard (U9100, U9200, U9300, U9400) which is dead. In fact, the 1v8 SSD and 2.5 SDD was short with the NAND Is this possible to replace these NAND ? I heard about encrypted NAND with the T2 It's seems to not boot even if these is no remaining short on the...
