Shouldn't the nand be clearly flashed under 2141?I saw a video of how they put 2nands on 6nands 2141. Do you just need to put one on one wing and turn off the other? But I only have nands flashed on 1990 4x128 and 1932 2x128. Without nand, should the t2 be in the dfyu correctly? And mine is 20v 0.04a without nand. I thought that the t2 simply can't wake up without all the nand -
I can bga reboll. I have a stable 20v. but only 0.04a stable when there is no nands. PPBUS_G3H stabil 12.6Leave a comment:

I put 4x128 from a1990 (u86 on u86, u87 on u91, u88 on u92, u89 on u93), but the situation did not change - first a jump to 0.23a and then a stable 0.05a+-. I thought that the reason was in the configuration with tsb4227 and 4228 because 2141 does not have tsb4228. removed (.
I put 2x128 from a1932 (u86 on u86 and u87 on u91) the result is the same 0.05a (0.04a-0.09a) but cyclically every 15s the amperage seems to be rebooting and the standby voltages disappear 1.8v and 2.5v. I read that this happens with a faulty SSD bank.
Unfortunately I don't have the original 5x128 for 2141, but...Leave a comment:

for some reason they don't like to help beginners here, or there's just no one here. I have a similar problem - 20v 0.04a. I think something along the lines of t2 - because it seems like all the voltages are like yours. but there's no PM_RSMRST_L. Do you have 5v on the board? because if you don't then you have the same problem as me. 5v on cd3217 -PP5V_S4_X_USBC_S4_X_USBCLeave a comment:

Don't have 5v on both sides maiboard (cd3217 does not do 5v).Leave a comment:

macbook pro a2141 20v 0.04A
Hi. Help!!! I'm at a dead end. I removed the faulty SSD,
removed the U9580,
removed all the coils that power the SSD,
removed the U9500,
replaced others the cd3217,
reflashed other the U2980
and still on the board 20V 0.04A.
There is no DFU!!!
here are the measurements on the board:
-P1V8_SLPS2R = 1.8V
-PP1V1_SLPS2R = 1.1V
-PP0V8_SLPS2R = 0.8V
-LDO_RTC = 1.5V
-PMU_SYS_ALIVE = 1.78V
-PPVBUS_USBC_XA (B105 U3100) = 19–20V
-PP3V3_G3H_RTC_X (near U3100) = 3.3V
-USBC_XA_USB_TOP_P = 2.3V
-USBC_XA_USB_TOP_N... -
Macbook screen does not display an image
Hello. I encountered such a problem - the MacBook screen lights up but does not display an image. Almost like a flexjgate in reverse). Maybe someone has encountered such a breakdown. The problem is in the cables or maybe in the t-con? -
What made me think of this was that they are the same price for models of the same generation. The only difference is the price of the T2 chip for 1 terabyte.Leave a comment:

Macbook pro T2 chip change
Hello. I'm interested in this topic)) - will the T2 chip from the MacBook Pro 13 fit the MacBook Pro 16 of the same year, the same SSD size? Maybe someone has tried it? -

I did flash it with dfu. On the main one there was monterey and on the broken one catalina. Then the internet recovery started. everything is ok)))
and I understand that on all MacBooks T2 after erasing it is necessary to restore only via the Internet, because by default the USB boot function is blocked...Leave a comment:

Macbook pro a2251 short ssd line
hello. I'm at a dead end. So, when flashing through dfu, I got an ssd error. I removed all the nand chips and u9000 u9080. As a result, I got 5 volts of consumption and everything is shorting - that is, it seems that all the contacts on the nand chips and yu9000 yu9080 are shorting to each other. Maybe there are a couple of units somewhere that don't short. and I don't know where to look next.
help -
It seems something came out of the DFU - now it is. The Alt key works, but the MacBook refuses to boot from USB. it still transfers the recovery to the Internet.Leave a comment:

MacBook Pro a2141 not installing macOS
hello. I have 2141 on which I can't restore macOS. When loading, no buttons are active, it immediately wants to restore the Internet. But then I see an error 2100f. It doesn't boot from an external USB.
I can't flash it through dfu because I don't know the version of macOS that was on it. Help
By the way, for some reason it heats up inadequately and the coolers are at maximum -
