I think you’re the only youtuber who reply comments that I’ve seen 👍👍 Can you please explain how you write the data on the nand ? Dont you have to read data first from the old nand?
good evening, nice video! I have a 820-01814-01 A1990 T2 the restoration cannot be done and the CPU heats up quickly cutting off the display at one point. need help please
I replaced all 4 NANDs as per the JC Programmer and put them at the correct places. All 4 are 00 of 0/1/2/4th Order. Power Rails are stable for more than 30 seconds. Pp2v5 Ppbus (12.3V) Machine detects in recovery mode. I did a bare board restore and got error 1. Connected the trackpad and everything else. Now i get USB Host Error 9. Where could i have gone wrong ??
Yep :). I’ll tell you in F. Though don’t take it as a guide since each equipment is different. To cut glue I used 460F and small nozzle cut under 45deg. For nand removal I used 760F on my hakko station with air at 4 and 10mm nozzle cut under 45deg. angle. Cleaning I did with 650F. Reball with 560F and air at 2. And resolder with 660F first with air on 2 and after it set moved air to 4 to make sure they soldered nicely
Thank you so much for your reply, I meant the FILES (I noticed you have a row on the left of JC program bellow iPHONE and IPAD ---- > MacBook PRO files. Do you download them? or does it come with the JC P13 software?@@applepietech
Nice video.. Im shocked on last minutes 😵💫
Yes, it was pretty scary, not sure how that happened but I intentionally did not cut that part out. No damage whatsoever, it landed flat :)
tremendous job Vlad. Keep it up!
Nice job mate 🙏🏻🙏🏻

JCIDRepair program has nand configuration files for some models so you can just write those to the nands.
@@applepietech thanks for the info. brother ❤️
Great job! 👌👍

Make sure you have charged battery plugged in. And make sure no damage anywhere else on the board
@@applepietech Thanks. Its done. AC2 was the issue!
❤️❤️❤️
all 8 NANDS position are fixed or can be soldered at any position ?
Hi
thanks for insights
How do you validate the nand you've bought from aliexpress is good enough ?
Nands used in this video were taken from a donor board. You can do couple read/writes on your nands and see how they perform.
where can we buy new ssd nand for a1990 2019 MacBook Pro 15.4 ?
Aliexpress, donor MacBook board or iPhone board
@@applepietech Are those nands compatible with 2018 Mac Mini?
Ouch 😂that was lucky. What temps in °C for the NAND desoldering/ resoldering and for cleaning up the new chips please?
Yep :). I’ll tell you in F. Though don’t take it as a guide since each equipment is different. To cut glue I used 460F and small nozzle cut under 45deg.

@@applepietech thanks Vlad great result
that could have been a very expensive mistake BB... ) well done Vlad brother
Yes, indeed.
good job! is it possible to replace only the defective ones from the same model donor board? it will work?
Thanks! No possible. You need to move all nand chips. Also nand chips from A1990 are also compatible with A1989
@@applepietech also backwards? by that you mean that is possible to use a1989 chips on a1990 without reprogramming?
@@luckduck84 Yes, if I am not mistaken. Same goes for A2251 model.
@@applepietech Thanks for the tips... again, nice job! keep making great content...
Hey, thanks for the video. Does the JC P13 come with MacBook Pro NAND files as well? How do I get them?
No, nand chips you can get from a donor board or buy on aliexpress
Thank you so much for your reply, I meant the FILES (I noticed you have a row on the left of JC program bellow iPHONE and IPAD ---- > MacBook PRO files. Do you download them? or does it come with the JC P13 software?@@applepietech
Files are located in software
amazing. Thanks so much for replying!@@applepietech
