kahit may power cable na yong jtag adapter

 

[Greed]

Try mo itong pin-out boss.

Pag wala pa-rin use this options:

* Pull-up resistor From 50-200 ohms (Makikita mo sa Z3x jtag yung pinouts sa baba)
* Pull-up VCC to 3.3V
* Solder only DAT0, CMD, CLK and Ground. For VCC and VCCq use usb cable+Power Supply
* Find testpoint

Same na din sa SM-J200GU...

 

[ultimate_jhomar]

update ko bukas kung mag anong status ng unit saya mga unit na hawak ko 6pcs

 

[ultimate_jhomar]

bali yong pinout ng vcc at vccq sa easy jtag yong 2.8v at 1.8v yon yung pinout ng vcc at vccq tama bako

 

[PERRYJUN]

sundan mo lang nasa guide... lagyan mo ng battery tsaka charger

 

[Greed]

2.8=vcc
1.8=vccq

 

[ultimate_jhomar]

sundan mo lang nasa guide... lagyan mo ng battery tsaka charger
