Assembled in the chassis, same error message. With both all connected as well as only tpad and battery The operation couldn’t be completed. (AMRestoreErrorDomain error 6 - Failed to handle message type StatusMsg (Operation failed)) [AMRestoreErrorDomain – 0x6 (6)] Error logs doesnt seems to...

Jumpered it to GND and did revive with bare board on desk, it fails with code 6 and just shows as Apple Controller - in Restore mode after it fails. Any ideas?

Do we know the power sequence of Apple silicon ? I cant find it on the schematics anymore. Unsure which ones are the secondary lines. With plain board on the desk - 20V / 0.07A - - connected to top left port PPVCC_S0_CPU - 0V PP1V2_S3 - 0V PP1V2_S0SW - 0V PP0V6_S0_DDRVTT - 0V PP2V5_S3 - 0V...

Data Recovery case, so cannot use DFU Restore No liquid damage, usual oxidation around C9081 from fluff and humidity. Inspected the board inch by inch no other oxidation or liquid. Only option i see is DFu Revive, but fails with code 6 when waiting to transition to Restore. Any suggestions?

I can confirm that this model does turn on with some/all AMP ICs removed Also 1V8_AWAKE should be in the 10-20Kohm range

Thanks, I think my only choice is to keep pulling amps out one by one until I that low resistance goes away. Isnt it? I tried to measure measure and compare resistance on C600/30/60 and C700/30/60. Its all hovering around 90Ohm. So Ill just roll the dice and keep pulling them out.

What is the best way to reball these ics? I am struggling with these glass based ones. hard to source these ics, yet alone a complete board. bravo

This Macbook came with organic matter damage, dead bug excitements around both side amp ics. After cleaning it turned on and worked for a bit, but when I tested the audio it shut down and didnt turn on anymore. When I start measuring I detected shorted UR630. Replaced UR630, no more shorts in...

C5250 voltage 12.50V with removed Fuse and no ticking. Where to next?

Extensive liquid around U630, short on RR631/2. Removed them as well as UR630/00, still clicking Can measure voltage fluctuations on the coil, swinging alot and on same tact. Replaced U5200 thinking it failed. Still same. Lift up L5230 to see if something afterwards is pulling but can see low...

Thanks, I've managed to source replacement board. Missing the days when we could just shove the SSD into a replacement board. Instead of dealing with Apple silicon/T2 crap

Reflowed, reballed and replaced the SMC. Still getting that small jump to 0.14 and sits at 0.01A with only heat signature around U7100 Cant see anymore corroded traces need to repair.

PPVRTC_G3H = 3.4V - with slight pulse of 0.2V PP5V_S5 - 5V pulsing to 3.8 for a sec and restores back to 5V PP5V_S4RS3 - 0V - pulses to 3.9V Lots of oxidation marks after being repaired previously Repaired corroded traces around U5110 Some work done around Y5110 as SMC silicone is removed...

Swapped UB090 from working board, still not transitioning to 20 without battery. Stuck at 5V 0.27A and cycles to 0A on the right ports every 10s Replaced UB300 again, also replaced QB300 as seems like there was sticky corrosion underneath.

OK I managed to charge the battery with donor board and now it turned on. This with original ROm However it is not charging on any ports. USBcs are working however as i can transfer the data. With battery connected left USBcs stays at 5V 0.24A Top Right USBs - 5V 0A Bottom right USBc - no...
