Hi, having some Problems with this mid 09 board. It was at a different shop before as the backlight didn't work and they told the customer they couldn't fix it. I actually had a talk with that other place and they said they used freeze spray to find the issue causing the backlight issue and and...

Hi, having some major issues with a 6s I am working on. Basically the phone came in with greyed out wifi and non functional bluetooth. I started by just recalling the WiFi Chip which did actually bring back wifi. But it got very hot and threw a temp warning every minute or so. So I removed the...

No seems to work fine. The only thing I found weird (could also be an OS Bug though) is that it goes to sleep while playing YouTube.... Yes original charger, though this reboot was on a genuine battery

Yup, maybe should get one soon. Also now found out what is the reason for the crashes according to macOS as I finally got a log... Is that of any use? Will try the new EFI file you sent today. Will report back on what happens. BTW as Long as the Machine is on all the Time and never goes to...

Oof gonna try tomorrow always a huge pain removing the chip soldering wired to the chip... Will report on how it goes.

Thanks for cleaning the Me Region, but it still does the same thing :(

We’re you actually able to see anything “wrong” with the old ME region? I’ll try flashing later...

Anyone able to help me clean the ME Region of that dump?

Only get about 1.7V...

Wouldn't swapping the SPI Flash from a donor do the same job?

Do I need an external Programmer for this?

Hi, after a bit of a break from board repair due to personal reasons im back at it again! I bought this A1502 13" late 2013 retina which has a super weird issue! It works just fine for a while but after like 30 minutes it cuts out and sometimes won't power up until you let it sit for a while. I...

Back to this old thread after over a month. Got a replacement U1950 in, made no difference. Also tested the original one on a known booting board and it worked. Any other ideas on what I can try?

Used a genuine 85w charger for these measurements

Yup, identical board. SMC_RESET_L is 3.38V PM_BATLOW_L is 0V SMC_PM_G2_EN is also 0V

Hi, have this 820-3462A A1425 2012 13" Retina Board that used to have a shorted SMC. Well I finally tracked one down an replaced it. Board still won't work though. It does have the orange light (so 3V42 definitely working) and PPBUS_G3H is normal. Any suggesting? Which rails should I post?

Hi, have a question. Is there anything theoretically possible to fix a1534 MacBook 12" Units with failed SSDs. I mean you can fix failed iPhone NANDs by replacing them and reprogramming the new one. Something similar possible here?

Okay, I think problem solved! Turns out U6900 had corrosion on it. Replaced it and it appears to charge again and the light works again
