[mobifone]

i bought atf 5 in 1 cable need to repair boot i9300 but always get error massage and not connect i read others people who use this cable have same problem and need some modification could someone explain if this cable needed modification and where to do. here is the log

Bro, this adapter have all pinout wrong, only GND is right... i've see the difference in one post but not remember where... you can see RIGHT pinout from RJ45 by X-Shadow here:

RJ-45 PINOUT During EMMC_MODE


1 - NOT USED (VBATT)
2 - Connect to eMMC Vcc and VccQ (Adjustable Power Supply)
3 - NOT USED
4 - Auxilliary CLK (Optional)
5 - CMD
6 - Primary CLK
7 - GND
8 - DATA_0

hope someone can show exactly where i should do modification

mobifone i have bought the atf 5in1 and made the post on the link above.

First you have to cut the line that goes from 5V to CMD, otherwise you risk to burn the emmc. Then you should resolder each RJ45 cable with the correct configuration, and make a bridge from the free wire to CMD.

I have bought from GPG thinking it was a good product, but is a *****

[mobifone]

Thank you so much ,but if you can spare time post picture of modification will be great.

Ok, this afternoon i will post a picture of my modified interface.

It is different from the original, because i have removed the power ic that gives 1.8v to use it on a custom board.

My GPG ATF5in1 now have only the 3.3v power ic, because i needed a second interface to use when i connect directly to the emmc when is on pcb , but i will show you where i have cut the 5V line and where i have bridged CMD.

I have doubts that JTAG and SD will work too with this interface, but i don't need them so i don't guarantee to you that this will work again after the modifications.

Hope gpg industries will comment/clarify on the subject and clearly tell what modification should be done so we can use the cable and all its features .over to you gpg to save your reputaion

Bro, listen me, GPG have very bud support and only want copy/paste other thinghs, like emmc/jtag gpg box, this cable itc... so if you want modific w/o wait more time this bad cable use link in post above, you find also picture of RIGHT pinouts from Atf, (X-Shadow), and WRONG pinout in this gpg cable, just you use only Right pinout and description from @laptopmd and u have working cable

here the picture that mobifone requested, this is how it look my interface now.

the 1.8v power regulator is missing because i needed for another homemade interface, but you can leave it here if you want.

I have cut the track on pcb between 5V and cmd, then i removed the pin connector and made a bridge between tms and cmd

I have desoldered the wires and resoldered on the right scheme, my wires are now :

1 - White
3 - Black
5 - Blue
7 - Brown
8 - Green

I USE ATF NITRO, don't know if this is the same for the big box ATF.

P.s. : if you still have connection problems, you can solder two 100ohm pull-up resistors between 3.3v pin and CMD and DATA0

first Thanks for the photo i have 2 last questions:
1.after i make this modification will i be able to use other featurs e.g jtag,molex
2.must i remove U1?

@mobifone, had answered in post #8 read:
1)

I have doubts that JTAG and SD will work too with this interface, but i don't need them so i don't guarantee to you that this will work again after the modifications.

2) yes U1 you need to remove

@laptopmd, what the wire can i see down the 3V3 point?

2) No no you can leave U1 here, so you have 1.8v pin too. I needed U1 on another board so i have removed it. Leave it here

@allumts : i don't have understood your question...
