CMD Timeout Error / Warning: CMD Pullup Level (0 mV)

[Reutskiy]

Excuse me, help me anybody please

------------------------------------------------------------
Z3X EasyJtag Software ver. 2.5.0.8

Loading eMMC Addon Firmware... IO: 2800 mV
Box S/N: 05FFD006640A08E5, ,FW Ver.: 01.58
Warning: CMD Pullup Level (0 mV) too low , check cables etc.!
CMD Active Level:0 mV
Box IO Level:2800 mV
CLK Rate:14000 khz

Can't init device, Reason: CMD Timeout Error
Done.
------------------------------------------------------------

Why my CMD Pullup level is 0 mV? I tried connect few emmc directly from the z3x easy jtag, and with moorc adapter.
I can't detect emmc with my box T_T

Is it necessary to disassemble the box? if yes, why it can was happed?

Hi
Please remove any adapter then press "Detect" and post log

[tedcen34]

important Note
in case of connection problems use pull-up resistors 5-200 ohm 0.25W from 1.8 to CMD and DAT0 lines
%100 working

directly from the z3x easy jtag to samsung i9082 board, without any adapters:
And with resistors 100 ohm

with resistors something changed.
it's the same error with any emmc voltag (1,8; 2,8; 3,3)
And from box CMD pin, voltage 1.3 when in programm is 1.8. It's ok? The same pictures with other voltages too.

up :P
anybody help please

[rodnei mayr]

estou com mesmo problema comprei essa caixa e nao funciona.

ajuda

[jmr]

have same problem how solved this, use other box and emmc is fine can connect but easy jtag always same error

[BABAK NURI]

Hi
I think you have short circuit in box pcb or phone or 20 pin of header

anyway,Can you test with emate pro?

[eumore79]

try to double check connection. its better to use microscope. sometimes it is only in connections. bad solder
i encounter this

With new logs
I'm soldered to emmc pinouts on phone board from z3x easy jtag (samsung i9082)

always logs
