I have samsung galaxy S3 duos (SCH I939D) , It is not launched in India. samsung has made it for China & Russia. Mine is fron China. The problen with the phone is that PLAY STORE is not running and phone is not receiving 3G network. And even there is not any option to change network mode to WCDMA. Can rooting or flashing solve my problem ?

And also somethings are in chinese language which cant be removed or deleted by me. As there are not any option to delete those chinese things. Can I delete them also. The OS of my mobile can be changed to English version ?

kindly reply soon

WARNING, remember that you will have ALL THE TIME this two voltage on the connector, so use this 2 pins ONLY and ONLY when dealing with eMMC direct!

Your image shows the different pins of the second image (the official Easyjtag) need to modify or are the same just with different names?

DAT0 = TDI?

CLK = TRST?

CMD = VREF?

internal power of easy-jtag box not enough for stable direct emmc read/write.
Please use external power.
Or build adapter or buy adapter.

Not a solution. Some chips need 1.8V level for cmd and 2.8V for VDD. So the problem is that you can have just 1.8 or just 2.8 on CMD and VSSQ with such solution.

This Thread is so unhelpful for ppl who are new in JTAG/EMMC. How do I find the Pinout on the PCB of the phone? where do i connect the wires on the phone. Pls stop saying it has already been answered because there is not a simple picture or a Turtorial. Every thread about ppl who have succesfully repaired their phones with JTAG/EMMS direct dont show any picture of the connection etc....sometimes i ask my self why ppl are that selfish

Hello Sir,

when we work/repair in another model but not in direct EMMC, is the modified box work ?
or we need to modified again into original state to make it work ?

pls.kindly answer.

oblio · 03-06-2014, 13:34

Until today there is no official application of Easy-Jtag that is using pin 17 or pin 19.
So my box is still modified.
